A major challenge of criminal intelligence analysis is to process large amount of semi-structured or unstructured data such as textual documents and videos and to extract useful information out of the data to support semantic search, sense-making and decision making. In VALCI, a computational framework is developed that incorporates concept extraction, ontology use and evolution, associative search, and image/video analysis for semantic search and knowledge discovery. In this white paper we introduce the key concepts have been applied and their corresponding technologies that have been developed to tackle the challenge.
