Description of conference:
One of the largest problems faced by criminal investigators, litigators, paralegals, triers of fact, and others interested in disputes about factual questions in legal settings is the sheer mass of evidence available. It is often difficult to remember, retrieve, and interpret voluminous evidential information, and important relationships and inconsistencies may go unnoticed as a result. Tools that support the storage, retrieval, and interpretation of large masses of evidence would therefore be of great use.
Psychological studies have shown that people's ability to remember, retrieve, and interpret information is greatly enhanced when they organize it in a way that is meaningful to them. Scholars of the law of evidence have long suggested that graphical representations of evidential arguments and inferences could help people make sense of masses of evidence. As early as 1913, John Henry Wigmore claimed that his charting method promotes rational thinking about legal evidence. Wigmore had only pencil and paper to draw his cumbersome graphs. Today computer software may make it possible for almost anyone to construct useful graphical representations of arguments and inferences related to large collections of evidence. If such software were combined with with existing database, document management, and search technology, documentary evidence could be stored and retrieved in accordance with the user's view of a case. This would facilitate the transfer of a case file from one person to another because it would make it easier for recipients of files to grasp the signficance of the evidentiary details of a case. Software for graphical representation of evidential argument is currently being investigated for use in various domains. Argument visualization software has been designed, for instance, to support the teaching of scientific reasoning and critical thinking skills (e.g., Belvedere, Reasonable, Araucaria, Convince Me), to support intelligence analysis, and to facilitate individual or collaborative problem solving (e.g., Questmap, SEAS). Moreover, current artificial intelligence research offers precise accounts of evidential reasoning and thus provides a clear semantics of graphical notations as well as computationall methods.
In the legal domain, fact investigators and litigators increasingly use software that supports the storage and retrieval of information in terms of conceptual and relational networks (e.g., Holmes 2, Analyst's Notebook). As yet, however, such tools offer little or no support for structuring thinking about information: existing software allows users to store evidentiary data in terms of events, objects, actors, and the relations among these things, but it does not allow users to represent how such data support or undermine factual hypotheses.
This interdisciplinary conference brings together scholars and practitioners from fields such as law, philosophy, computer science, artificial intelligence, cognitive psychology, and linguistics. The following topics and issues will be addressed:
- New and current graphical means for visualization of factual inference and proof.
- Semantics of graphical notations: what are the underlying theories of evidential reasoning, including jurisprudential, philosophical, psychological, rhetorical, logical, and mathematical theories?
- Software tools that are currently available or under development for graphical representation of factual inference and proof.
- Potential contexts for the use of such software (e.g., criminal investigation, intelligence analysis, trials, and law teaching).
- Can graphical representation of evidential argument support automatic evaluation of hypotheses?
- How can current insights into human-computer interactuions be exploited to increase the usefulness of such software; e.g., how can visual complexity generated by large masses of evidence be managed?
- Are there pertinent empirical studies and findings about real-world use of evidence-charting methods in legal and other contexts?
