Search, retrieval, and management of multimedia contents are challenging tasks for users and researchers alike. The aim of ESentencias Project is to develop a software-hardware system for the global management of the multimedia contents produced by the Spanish Civil Courts. We apply technologies such as the Semantic Web, ontologies, NLP techniques, audio-video segmentation and IR. The ultimate goal is to obtain an automatic classification of images and segments of the audiovisual records that, coupled with textual semantics, allows an efficient navigation and retrieval of judicial documents and additional legal sources
