Thesaurus-based Retrieval of Case Law

Michel CA Klein, W. van Steenbergen, E.M. Uijttenbroek, A.R. Lodder, and F. van Harmelen, In JURIX Proceedings. IOS Press, 2006.

In the context of intelligent disclosure of case law, we report on our findings

on methods for retrieving relevant case law within the domain of tort law from

a repository of 68.000 court verdicts. We apply a thesaurus-based technique to find

specific legal situations. It appears that statistical measures of term relevance are

insufficient, but that explicit knowledge about specific formulations used in law

and case law are required to distinguish relevant case law from irrelevant. In addition,

we found out that retrieving legal concepts with an “interpretive” character

requires a different method than retrieving concepts that do not require additional

interpretation.
