Loge-Expert*: Strategies to Integrate Legal Knowledge Modelization, Non- Expert User Interface, and Textual Data Base into the Developpement of an Expert System in Law

Our paper will present three problems we have been exploring for the last two years. The first concerns modelization and formalization of legal knowledge. The second one refers to the communication between the user and the machine, since we have chosen to develop an expert system in Housing law oriented towards the general population. The third problem relates to the textual data base we have built in order to document the knowledge base of Loge-expert. At the moment, it contains some of the textual legal sources traditionally used by lawyers. From this two-year experiment with Loge-expert, we have learned that the development of an expert system in law is an iterative operation which includes simultaneous exploration of different dimensions such as the conceptualization of the specific legal field as well as the conceptualization of the communication devices between that legal expertise and the user or the conceptualization of the linguistic and textual dimensions of that legal expertise.
