We present a dialogue system that enables the access in natural language to a web legal information retrieval system. The documents in the IR system are composed by the set of documents produced by the Portuguese Attorney General. These documents were analyzed and an ontology describing their structure was defined. Then, they were automatically parsed and a(More)
A logic programming framework for the definition of cooperative multi-agent legal web information retrieval systems is proposed. Cooperation is achieved through the use of dialogue processing techniques, namely, the inference of the user intentions and the existence of a pro-active system behaviour, which tries to help users in their searches. The proposed(More)
We propose a framework for a collaborative legal information retrieval system based on dynamic logic programming. In order to be collaborative our system keeps the context of the interaction and tries to infer the user intentions. Each event is represented by logic programming facts which are used to dynamically update the previous user model. User(More)
The approach followed by the University ofÉvora team in order to build a system able to participate in the QA-CLEF task is described. The system is based in two steps: for each question, a first information retrieval task selects a set of potentially relevant documents; then, each of these documents is analysed trying to obtain their semantic representation(More)
