Computer Aided Legal Support System: An initial framework for retrieving legal cases by case base reasoning approach

Law is largely about cases, it is particularly an interesting domain for CBR researchers. The paper explains about how lawyers retrieve information in the process of legal research and reasoning. CALLS (computer aided legal support system), is a reasoning method for determining similar cases by executing a case-similarity calculation step and utilizing a distribution of values of fields for calculation of reasoning results of cases having high similarities. In this paper we provide an overview of our case base reasoning approach in legal domain and outlined the initial frame work of analyzing and retrieving the cases. We discuss the key components of CALLS, in general and the correspondence of those elements in CALLS. The domain for investigation through out the paper is the law of negligence. Finally we concluded the paper with worked through example.
