CA 2624865

To facilitate legal research, companies, such as Thomson West provide subscription-based online information-retrieval systems. Seeking to improve these and/or related systems, the present inventors devised, among other things, an exemplary legal research system that performs a conventional search to identify a set of starter documents and then leverages the metadata associated with these starter documents to identify another larger set of relevant documents. Documents in this alternate set are then scored using, for example, a learning machine and feature vectors that account for metadata relationships between the starter documents and alternate documents.

L'invention concerne des systèmes de récupération d'informations en ligne basés sur des souscriptions, proposés par des sociétés telles que Thomson West, et destinés à faciliter les recherches juridiques. Afin d'améliorer ces systèmes et/ou les systèmes associés, la présente invention propose, entre autres, un système de recherche juridique exécutant une recherche classique pour identifier un ensemble de documents de recherche afin d'identifier un ensemble de documents de base, puis utilisant les métadonnées associées à ces documents de base pour identifier un autre ensemble de documents d'intérêt à plus grande échelle. Les documents de cet autre ensemble sont alors évalués au moyen, par exemple, d'une machine d'apprentissage et de vecteurs de caractéristiques représentant des relations de métadonnées entre les documents de base et les autres documents.
