Abstract

The Artificial intelligence revolution is happening and is going to drastically re-shape legal research in both the private sector and academia. AI research tools present several advantages over traditional research methods. They allow for the analysis and review of large datasets (‘Big Data’) and can identify patterns that are imperceptible to human researchers. However, the wonders of AI legal research are not without perils. Because of their complexity, AI systems can escape the control and understanding of their operators and programmers. Therefore, especially when run by researchers with insufficient IT background, computational AI research may skew analyses or result in flawed research. Premised thus, the main goals of this paper, written by Ronald Yu and Gabriele Spina Alì, are to analyse some of the factors that can jeopardize the reliability of AI-assisted legal research and to review some of the solutions to mitigate this situation.

INTRODUCTION: THE A1 REVOLUTION HAS BEGUN

Artificial Intelligence (AI), i.e. the ability of computers to exhibit human-like cognitive abilities, is already changing the transportation, financial and medical businesses.Footnote 1 According to some forecasts, computers will replace humans in one-third of traditional jobs by 2025.Footnote 2 The legal business will be no exception in this revolution and the legal profession has already begun to adopt AI technology over the past several years.Footnote 3, Footnote 4 Factors driving the adoption of AI include the challenge lawyers face to act more strategically and make better use of technology, especially when confronted with a sluggish growth in the demand of legal services and steep declines in productivity. This scenario drives firms to adopt AI as part of a “more for less” cost-saving solution.Footnote 5

A number of legal AI systems have been introduced recently. These can be loosely grouped into three macro areas:

  • • Unstructured data analysis and due diligence: Where AI tools are employed to uncover background information and have so far had the most impact on the field. This includes contract analysis, document review and electronic discovery. In the field of contract review, some of these systems claim time and cost reductions up to 90% when compared to manual review.Footnote 6,  Footnote 7 JP Morgan's Contract Intelligence (or COIN) is even said to need only a few minutes to perform tasks that would take thousands of hours of human work.Footnote 8

  • • Legal research & analytics: For instance, CaseMine provides more accurate legal researches and even allows unravelling covert legal relationships by mapping linkages between different cases.Footnote 9 Other applications analyse past case law, win/loss rates and a judge's history for trends and patterns. For example, there is ongoing work to apply AI to analyse the rulings of both judicial bodies (the U.S. Supreme Court)Footnote 10 and quasi-judicial bodies (the U.S. Patent Trial and Appeal Board).Footnote 11 China's Supreme People's Court started using an AI-enabled tool to search for precedents and identify analogous decisions to guide judges.Footnote 12 Some companies already offer similar systems to private law firms,Footnote 13 while other focused on prediction technology that tries to anticipate litigation outcomes and opposing arguments.Footnote 14 In the field of intellectual property, some AI tools help lawyers navigating large IP portfolios, warning of existing legal conflicts with prior IP and identifying potential brand name threats.Footnote 15

  • • Practice management applications: Including electronic billingFootnote 16 and document automation, i.e., programs helping lawyers in the drafting and redaction of legal documents and briefings.Footnote 17 Other applications are meant helping companies with regulatory compliance in specific jurisdictions, e.g. China.Footnote 18

THE PRESENT IMPACT OF A1 IN THE LEGAL PROFESSION AND ITS IMPLICATIONS

The legal profession has only begun realizing the benefits of AI.Footnote 19 Legal teams are finally embracing AI and some firms have even started their own in-house big data analysis/AI teams,Footnote 20 or even introduced AI-based products.Footnote 21 However, we are still far from a generalized diffusion of AI technology among firms and researchers. Evidence from the US shows that both private practice and in-house lawyers have so far been reluctant to accept AI and that there has even been a low rate of adoption of new technology in general.Footnote 22,  Footnote 23

As for the next future, over half of in-house counsels believe the impact of automation will be “significant” or “very significant”, while only 3% believe automation will have no impact at all.Footnote 24 U.S. consulting group McKinsey estimated that 22% of a lawyer's job and 35% of a law clerk's job can be automated.Footnote 25 Similarly, 49% of the 386 US firms participating in Altman Weil's 2017 Law Firms in Transition reported to have created special projects and experiments to test innovative ideas or methods, and that they were using technology to replace human resources with the aim of improving efficiencies.Footnote 26

The greater adoption and accessibility of legal AI could bring numerous benefits to many areas of law and to the society in general. For example, a study of hundreds of summary judgment briefs in employment discrimination found that the vast majority of plaintiffs’ briefs omit available case law rebutting key defence arguments. Many of these briefs fell far below basic professional standards with incoherent writing or no meaningful research.Footnote 27

There are many ways in which AI can remedy the problem of sub-standard lawyering. AI allows for the analysis and review of large datasets (commonly referred to as “Big Data”) and is able to identify patterns that would be inevitably overlooked by a human observer. For instance, legal analytics software applications are able to process millions of court documents and can offer lawyers insights on potential litigation strategies and even simulate how a specific judge may respond to a given motion.Footnote 28 AI can also improve access to legal information. It can enable lay users to pose sophisticated legal inquiries and get plain answers from cheap and easily accessible AI systems. In this way, AI legal applications overcome past problems of accessing and mastering costly online services that were both incomplete in coverage and cumbersome even for experts to use, resulting in better justice for more people.Footnote 29

AI-SPECIFIC PROBLEMS

However, as more lawyers, law students and legal researchers embrace AI, they need also be aware of the potential dangers of placing blind faith in the impartiality, reliability and infallibility of legal AI.Footnote 30 As already noted in a 1970 Stanford Law Review paper: “Lawyers might rely too heavily on a restricted, and thus somewhat incompetent, system with a resulting decline in the quality of legal services”.Footnote 31 Following are some of the features that undermine the reliability and accuracy of AI in the legal profession and academia.

The myth of impartiality

AI systems are programmed using a set of algorithms,Footnote 32 and ‘learn’ by studying data to identify patterns.Footnote 33 They are thus subject to both biases inherent in the algorithms employed - as different sets of engineers bring very different biases and assumptions to the creation of algorithms - and the data sets used. Different legal AI systems operate with different algorithms and, in many cases, on different datasets. Thus, despite claims of comprehensive and all-encompassing coverage, it is not surprising that different legal AI systems can produce different results.

This observation was reinforced by researchers who compared the results of the same legal search entered into the same jurisdictional case databases of Casetext, Fastcase, Google Scholar, Lexis Advance, Ravel, and Westlaw. The databases returned widely divergent results: an average of 40% of the cases was unique to one database, and only about 7% of the (same) cases were returned by all six databases.Footnote 34

Even law-makers are starting to acknowledge the implications of AI biases. For instance, the 2016 EU General Data Protection Regulation (GDPR) is among the first laws to recognize the effects of algorithmic decision-making on the “fundamental rights and freedom of natural persons”Footnote 35 and to address the issue of potential AI abuses.Footnote 36 Recital 71 of the Regulation even speaks of the implementation of “technical and organizational measures” that “prevent, inter alia, discriminatory effects on natural persons on the basis of racial or ethnic origin, political opinion, religion or beliefs, trade union membership, genetic or health status or sexual orientation, or that result in measures having such an effect”.Footnote 37 Under this perspective, the EU Data Protection Regulation seems to prohibit processing data on the basis of membership to special categories. Accordingly, companies operating in the EU will have to utilise algorithms that do not take into account characteristics such as gender, race or religion.Footnote 38

Algorithmic bias

As alluded to earlier, algorithms codify human choices about how decisions should be made and thus are not immune from the human values of their creators.Footnote 39 They can reinforce human prejudices as they are written and maintained by people and because machine learning algorithms adjust what they do based on people's behaviour.Footnote 40

Problems of algorithmic bias were highlighted in two famous cases concerning image recognition AIs. It was revealed that Hewlett-Packard's implementation of a feature-based face localization algorithm did not detect Black people as having a face.Footnote 41 The algorithm measured the difference in intensity of contrast between the eyes and the upper cheek and nose of a human face and because of the choice of these parameters it did not work properly on darker faces in certain light conditions.Footnote 42 Similarly, Google Photo's image recognition algorithm started tagging black people as gorillas. In the short term, Google was unable to fix the algorithm and solved the problem by removing words relating to monkeys from Google Photo's search engine.Footnote 43

Data bias

In addition to algorithmic biases, poor or flawed datasets used by AI systems are also a cause of concern. AI based on neural networks identifies recurring patterns on existing datasets and makes future predictions based on these patterns. However, there is a strong risk that AI may reiterate and even amplify the biases and flaws in datasets, even when these are unknown to humans.Footnote 44 In this sense, AI has a self-reinforcing nature, due to the fact that the machine's outputs will be used as data for future algorithmic operations.Footnote 45

In a well-known experiment, researchers found that employers were 50% more prone to shortlist job applicants with white-sounding names rather than those with African sounding ones.Footnote 46 The fear that AI recruiters would start amplifying human hidden biases became reality an AI used by Amazon to shortlist job applicants started discriminating women candidates.Footnote 47 Similarly, there is a widespread concern that AI-powered banking software might start applying higher interest rates on racial grounds.Footnote 48 Also, researchers at the University of Virginia, who tested two large collections of labelled photos used to “train” image-recognition software, not only discovered that the images displayed a predictable gender bias in their depiction of activities such as cooking and sports (e.g. images of shopping and washing were linked to women while coaching and shooting were tied to men) but that machine learning software trained on the datasets amplified those biases.Footnote 49 Considered the foregoing, it should not surprise that experts have been warning that outsourcing decisions to AI may reinforce human prejudices rather than lead to more impartial, fair or transparent decisions.Footnote 50

The EU GDPR tries to solve the issue of data bias through the means of “data sanitization”, i.e. by preventing the inclusion of variables relating to categories such as race, gender or sexual preferences.Footnote 51 The data sanitization requirement can be interpreted as relating to explicitly discriminatory variables (e.g., skin colour) or to variables that have an implicit or statistical discriminatory incidence (e.g., height as a proxy to distinguish between men and women).Footnote 52

Nevertheless, data sanitization is a difficult application to AI systems. Under the first reading of the GDPR, sanitization implies cleansing an algorithm from explicit discriminatory instructions.Footnote 53 This is rarely the case for AI systems, which take decisions based on recurring patterns in large databases, rather than because of explicit variables embed in their initial algorithm. By contrast, cleansing the data from all variables having even a potential discriminatory impact is infeasible because it would mean depriving the AI of the necessary operating information and impair its ability to reach accurate or altogether meaningful conclusions.Footnote 54

There are also issues of statistical bias in the management of data,Footnote 55 translating into outdated data, selection bias,Footnote 56 sampling bias, or misleading statistics.Footnote 57 Finally, there are collection or modelling errors. For instance, the problem of collection errors was highlighted in the 2016 American presidential election, when pollsters incorrectly predicted the results just days before the election, due to, inter alia, improper sampling, limitations in data collection or an electorate too complex to poll with any accuracy.Footnote 58 Institutional bias can also become a problem. For example crime reports, which are assumed to be random and representative, show significant geographical biases, i.e. if the police concentrate their patrols in certain areas there will be more data generated in those neighbourhoods.Footnote 59

Bad data practice could be caused by honest statistical or computing error (which may range from spreadsheet formulae, overflow or format conversion errors), misunderstanding of data and its applicability to the task on hand, misapplication of methods or failures to normalize data.Footnote 60 Finally, there is also the issue of malicious manipulation or corruption of data caused by cybercriminal or malicious hacking activity. For example, some speculated that data tampering was behind the problems Microsoft Tay experienced as the Tay had been subjected to “a coordinated attack by a subset of people” who “repeatedly had the bot riff on racist terms, horrific catchphrases, etc”.Footnote 61 Similarly, researchers at the University of Southern California found that nearly 20% of the conversations surrounding the 2016 US presidential election on Twitter may have actually been created by bots that they speculate had been created by parties seeking to manipulate election results.Footnote 62

Inference and prediction

Algorithms are very poor at distinguishing between causation and correlation, and thus there is always a risk of conclusions based on wrong inferences. For example, the purchase of a hang-gliding magazine could be correlated with a risky lifestyle when the purchaser's true motive is an interest in photography.Footnote 63  Analysis models might also be flawed by incorrect assumptions, proxies, or presumptions of causal relationships where none actually exist (this is the problem of p-hacking).Footnote 64 Users may also attribute greater predictive capability to AI systems than is justified. Illusions of predictability may be caused partly by users’ lack of understanding of the technology and the systems themselves.

AI-powered predictive analytics and language translation systems commonly use statistical methods for dealing with unknowns and data limitations,Footnote 65 but these methods are not always followed by investigative processes that resolve the related unknowns and validate the system assumptions.Footnote 66 Users need not only to understand both that probabilities presented are not outright forecasts and that past historic behaviour does not necessarily predict future outcomes but that the models used may have limitations. For instance, a model attempting to ‘predict’ the voting behaviour of American Supreme Court Justices by examining overall past results will not provide a complete or accurate picture if it does not also consider long-term trends, e.g. that Supreme Court Justices have, on the whole, become more ‘liberal’ over time.Footnote 67

Input and output limitations

Legal AI systems must also be able to correctly interpret users’ inputs. Though AI systems have made significant progress in understanding human language,Footnote 68 there are still significant morphological and semantic challenges to be overcome – especially where non-English languages are involved.

With respect to morphological challenges – a system needs to correctly understand what the query is. Where a foreign language is involved, the system must not only provide correct translations of individual words but also distinguish the meaning of compound words. For example, a legal AI may need to know that the Chinese word for ‘Canada” is a combination of the characters for “to add”, “to hold” and “big” (加拿大) that, when read sequentially, phonetically approximates the English word CanadaFootnote 69 and that the specific grouping of 加拿大 needs to be translated as ‘Canada’ rather than as individual component characters.

The system must also be able to correctly perceive the relationship between words, as this is key to understanding the entire meaning of a law or regulation. For instance, while the Chinese sentence 網下和網上投資者獲得配售後, 應當按時足額繳付認購資金Footnote 70- can be translated as: “After offline and online investors receive the placement, they should pay the subscribed-to funds on time and in full”, a semantic mistake made by a machine could confuse dependency of the clauses and translate this as requiring the funds to pay the investors once placement has been completed.Footnote 71

Unpredictability

AI systems are capable of surprising behaviours, sometimes due to external inputs, sometimes because of their own internal structure. Complex AI neural networks consist of several layers of electronic synapsis, which process and convert a given input into an output.Footnote 72 They learn by themselves via a trial-and-error process, similarly to what happens in biological brains.Footnote 73 Nowadays, AI can teach themselves how to perform complex tasks that only a couple of years ago were thought to require the unique intelligence - or deceptive capabilities - of humans.Footnote 74

Part of the problem is that developers do not really know how the algorithms used by such systems operate. Deep learning machines can self-reprogram to the point that even their programmers are unable to understand the internal logic behind AI decisions. In this context, it is difficult to detect hidden biases and to ascertain whether they are caused by a fault in the computer algorithm or by flawed datasets.Footnote 75 For this reason, neural networks are commonly depicted as a black box: closed systems that receive an input, produce an output and offer no clue why.Footnote 76

To provide an example, a research group at Mount Sinai Hospital in New York applied deep learning to the hospital's database of patient records, creating a program named Deep Patient. When tested on new records, Deep Patient proved proficient at predicting diseases. Without any expert instruction, it discovered patterns hidden in the hospital data that seemed to indicate when people were on the way to a wide range of ailments, including liver cancer and even schizophrenia. Its developers, however, had no idea how Deep Patient learned to do this.Footnote 77

For all these reasons, when systems capable of self-learning are exposed to external inputs the results can be unpredictable and even whimsical. In October 2014, a bot tasked to buy random items from the web bought 10 pills of ecstasy from the dark web. Interestingly enough, the Swiss police arrested the robot while releasing the programmers from any wrongdoing.Footnote 78

Microsoft's TAY chatbot had to be shut down soon after its release because it began tweeting offensive comments.Footnote 79 The chatbot behaviour was later ascribed to the widespread diffusion of racist comments online. Some even suggested that TAY's experience validated the Internet adage that as an online conversation increases in length, the greater the likelihood a comparison to Hitler will materialize.Footnote 80 Others simply raised the possibility of hacking.Footnote 81

Google DeepMind's AlphaGo achieved historic success when it became the first computer program to defeat a world champion at the ancient game of GO.Footnote 82 AlphaGo playstyle had initially been described by some as ‘creative and intriguing’Footnote 83 causing evident unsettlement to his human opponent.Footnote 84 Yet that version of AlphaGo was subsequently defeated by a more advanced version (AlphaGo Zero) that learned to play Go without the constraint of human knowledge.Footnote 85 As a result, Go players worldwide started to re-evaluate centuries of inherited knowledge.Footnote 86 Some perceived AlphaGo's success as the definitive evidence of the creative capabilities of AI, especially considering that its playstyle was not anticipated by its developers.Footnote 87

Finally, there are also spill-overs risks to consider. AI systems may be employed proactively: for example to review data as cases come up and send cases, laws and regulations directly to a lawyer interested in a particular area; or be integrated with other systems or databases for, e.g., policy decision making.Footnote 88 Thus there is a risk that the consequences resulting from improper information from a legal AI system will cascade to other areas.

POTENTIAL SOLUTIONS

Fears of AI systems as black boxes, as well as concerns regarding potential implementations of AI technology in automatized weaponry and cyber attacks have sparked calls to ensure greater reliability, transparency and ethical alignment of AI.Footnote 89 There are several potential solutions to the challenges posed by AI to legal researchers. These are not mutually exclusive. The first four solutions proposed below operate upstream, i.e., they require institutional intervention from ruling bodies, universities or corporations. Conversely, the last set of solutions tries to empower researchers and practitioners with an array of best practices to remedy to the unpredictability, randomness and unaccountability of AI-driven legal research.

Education

Law schools have recognized the trend towards the use of AI and have begun creating new programs to teach the next generation of lawyers how to use these platforms and speak intelligently to the people building them. For example, the Harvard and MIT law schools nowadays jointly offer a course entitled ‘The ethics and governance of artificial intelligence’. The course covers, among the others, topics such as algorithmic bias, risk assessment and predictive policies.Footnote 90 In 2016, The Georgetown University Law Centre in Washington even pioneered the elective course “Programming for lawyers” where student teams, under the supervision of legal services organizations, are asked to build an application to facilitate access to justice.Footnote 91 Several Australian universities have followed this lead.Footnote 92 For instance, in 2017, The University of New South Wales launched “Designing technology solutions for access to justice”, an elective meant to teach law students with no IT background how to design legal information systems.Footnote 93

Courses of this kind are still at a pioneering stage and are offered by only a handful of universities worldwide. They also rarely cover AI-powered legal technology, focusing either on the implications of AI technology in the legal systems (e.g. liability and IP) or on traditional programming. In the future, it will be important to educate law students about the functioning and limitations of legal AI systems; with IT/AI law courses covering topics such as a taxonomy of the different types of legal AI/Big data systems, AI inference and predictive errors and input and output limitations.

Audit/ rating services

Experts have proposed the idea of an audit rating service to validate and certify the quality and accuracy of AI systems.Footnote 94 Audits have already been successfully applied to fields such as automated online advertisement, interest rates and pricing.Footnote 95 As noted earlier, use of statistical and other methods for dealing with unknowns and data limitations commonly employed in AI systems should be followed by investigative processes that resolve the related unknowns and validate the system assumptions, and should perhaps extend to the data and the models used.Footnote 96 In the field of personal data protection, the EU GDPR takes a step towards the diffusion and implementation of third-parties audits. The regulation favours the establishment of mechanisms such as certifications, seals and trademarks as long as they are granted through a process that is both transparent and subject to periodic review.Footnote 97

Establishing a certification system will not be an easy task, due also to the potential resistance of traders. Commercial providers could be reluctant to share information on their models or have their systems openly compared to their competitors. For instance, relevant litigation in the United States has shown that website terms of service prohibit most of the activities needed to conduct strict auditing to unveil discriminations on the Internet.Footnote 98 Also, as it will be shown later, it remains an open question whether there should be a legal requirement in any jurisdiction to disclose AI proprietary information to facilitate third-party reviews.

There are also pragmatic problems related to funding, insofar as there could be limited demand for such an auditing service. Corporations might also be updating their models so frequently as to make operating such a rating service impractical or too expensive. There will also be difficulties related to setting appropriate review standards, finding qualified reviewers and operating the scheme. These could prove a significant challenge given that they would require expertise in both legal and technical fields. A last problematic factor would be keeping the review criteria secret, with a view of preventing vendors or other parties from manipulating the results.

Algorithmic transparency

There also have been calls for greater algorithmic transparency, i.e., to oblige companies to release some mandatory information on their AI algorithms, in order to detect potential bias.Footnote 99 In the US, these claims are usually confronted with the observation that algorithms have proprietary nature and are protected under trade secret law.Footnote 100 In the European Union, a first step towards transparency has been taken with the aforementioned General Data Protection Regulation. This instrument provides European citizens with a right of explanation, i.e., to be informed about the reasons behind any algorithmic decision affecting them.Footnote 101 Again, this measure aims at avoiding automated decisions based on discriminatory parameters, such as race, gender or religion.Footnote 102

Others emphasize that transparency alone is inadequate to solve the problem of AI discrimination. Indeed, both the complexity of neural networks and the size of the datasets on which they are trained make AI internal logic inaccessible to human scrutiny.Footnote 103 Moreover, greater transparency neither solves the problems of data bias nor of the quality of the overall results returned by a legal AI.

Self Explanatory AI

As explained earlier, because AI learns from the surrounding environment and past mistakes, even programmers struggle to understand intelligent machines’ internal logic and decision-making. Against this background, calls for greater understanding of AI inner procedures are ubiquitous.

At the institutional level, the US Department of Defence is currently working on what is defined as ‘Explainable Artificial Intelligence’ (XAI), running a project that aims to create a suite of machine learning techniques that: a) Produce more explainable models, while maintaining a high level of learning performance (prediction accuracy); and b) Enable human users to understand, appropriately trust, and effectively manage artificial intelligence outputs.Footnote 104

XAI would help AI meeting the requirements set by the EU GDPR, which, as anticipated, entitles data subjects with a right to explanation, i.e., the right to obtain meaningful information about the logic involved in automated decision making.Footnote 105 XAI would be especially useful considering that the GDPR prescribes that the relevant information has to be provided in a concise, transparent, intelligible and accessible manner.Footnote 106,  Footnote 107

Private firms and research institutes are also working on teaching AI systems how to make themselves more understandable. For instance, a team at Microsoft is trying to teach AI to show how it weighted every single variable in evaluating mortality risk factors.Footnote 108 Similarly, a team at Rutgers University is working on a deep neural network that provides users with examples that demonstrates why it took a specific algorithmic decision.Footnote 109 Another project at the University of Berkeley involves lashing two neural networks together, tasking one to describe the inner procedures running inside the other.Footnote 110 Finally, an international team consisting, among the others, of researchers from Facebook, Berkeley and the University of Amsterdam has taught an image recognition software to show the evidence he relied upon to reach its decisions.Footnote 111

Scholars and experts have already emphasized how we cannot blindly outsource moral decisions to machines. Under this perspective, understanding AI internal logic is a first step towards ensuring full accountability for computational legal research and automated legal decisions.

Best practices for legal researchers

Finally, as for more traditional research methods, there are some best practices that legal researchers should observe to avoid skewed or flawed results. These may be of particular importance while AI systems get more transparent and easier to understand by legal researchers.

Utilize multiple AI systems

As mentioned earlier, different legal databases are likely to return different results for the same query. Randomness may easily escalate in the field of AI. Indeed, neural networks learn from past failures, are able to self-modify their internal algorithm and are potentially trained on different datasets, and therefore each AI shows unique traits. Given that, legal researchers might need to compare outputs from different programs to detect flaws in the AI utilized and increase research accuracy.

Trying different inputs

AI systems are able to analyse and formulate replies to more complex questions than traditional systems based on Boolean logic. For instance, instead of returning an array of documents containing the words searched for, legal AI systems may be able to come up with precise and definite answers to questions such as what are the statutory exceptions to copyright infringement in a given jurisdiction.Footnote 112 Applications of this kind are often structured as natural language processing software, i.e. systems that work by calculating the probability that words may be found close to one other based on statistical inferences.Footnote 113

For instance, the word “parody” is to be found close to words such as “exception” or “limitation” across EU copyright statutes and case law.Footnote 114 Therefore, modern AI research software may be able to provide a list of results when asked in which European countries parody is an exception to copyright infringement. However, natural processing systems may fail in jurisdictions where the statistical dependency between the words “exception” and “parody” is weaker. For instance, the Italian copyright statute does not include parody among the potential exceptions to copyright infringement. Nevertheless, courts have recognized that parodies have to be protected as fully independent creations on the basis of some of the guiding principles of the Italian Constitution, such as freedom of speech and of artistic expression.Footnote 115

Once again, the circumstance that legal researchers are unaware of the internal logic of AI systems requires that they exercise extra-care before trusting AI outputs. Like traditional research methods, running multiple queries using different keywords, relaxing time constraints or rephrasing the question asked to the software can help to detect biased, inaccurate or flawed research results.Footnote 116

Human monitoring

As advocated by some scholars, ex-post human monitoring might be a tool to detect and correct cases of algorithmic discrimination.Footnote 117 In the world of online video games, gamers have spontaneously established committees to adjudicate, correct and sanction game violations.Footnote 118 Combined with greater algorithmic transparency, crowd-level human monitoring might constitute a potential remedy to tackle skewed results and provide feedback to software engineers.Footnote 119

In fields such as legal analytics and prediction technology, human intervention is also essential to avoid outsourcing moral responsibilities to machines.Footnote 120 Similarly, legal researchers cannot over-trust computers. Even though human's ability for empirical analysis is greatly surpassed by machines’ computational ability, researchers should crosscheck computer's outputs with results obtained through traditional research methods on smaller data samples. This might be a way to ensure that AI research aligns with human values and to try to spot data or algorithmic biases.

CONCLUSIONS: THE ROAD TO THE FUTURE

The present paper is meant as a warning against over-trusting AI outputs and has provided an overview of the problems affecting AI computational research and reasoning in the legal field. As AI becomes progressively more accepted among legal practitioners and academics, the duty falls upon researchers to keep up with the diffusion of AI to ensure that algorithmic decisions align to human values and that AI-driven research conforms to appropriate qualitative and ethical standards.

As anticipated, this is a first step in the exploration of the challenges posed by legal AI. Future research should analyse more narrowly-scoped problems and look for more in-depth insights, for which the close collaboration of legal professionals and IT experts will be necessary. Only through their joint efforts, will it be possible to implement new techniques and strategies to remedy AI biases, as well as to explore new ways of introducing greater AI transparency without compromising the intellectual property of AI vendors.

In the era of crypto currencies, self-executing contracts and robots showing superhuman intelligence, there is a widespread fear that computers might one day replace humans in the legal industry and in the management of the legal system as a whole.Footnote 121 It is too early to know whether this day will eventually come, but what is certain is that until then it is up to humans to fix both the legal system and artificial intelligence.
