The traditional evidence retrieval method is not able to identify the word semantic in forensics user question, only make the mechanical matching, in order to improve the efficiency of evidence retrieval, get satisfactory retrieval results, this paper proposes an ontology-based evidence retrieval method, through the concept extraction from forensics data and query, concept interconnection graph construction, to realize the semantic expansion.The experimental results demonstrate that this method is superior to the traditional keyword-based retrieval method and able to perform evidence retrieval on a conceptual level.
