Access to legal documents has been hampered by the lack of attention for specific user groups accessing such documents. In this article, we focus on one of these user groups (legal professionals), who can benefit from specific types of cross-lingual information retrieval for, e.g., comparative law research. We propose to use legal definitions as anchor points in legal documents. Through the body of EU legislation, these anchor points can support a network of concepts between different jurisdictions. A model is presented containing the different entity types and relations types for building such a network, which can be implemented in the WordNet architecture.
