Semantic Signatures® are a new way of representing and analyzing semantic information (meaning) in text. Semantic Signatures, produced by TextWise’s Trainable Semantic Vectors (TSV) technology, provide a rich semantic representation of the multiple concepts and topics contained in a body of text. Semantic Signatures can be constructed for a wide range of texts including individual words, phrases, word lists (e.g. metadata), short passages (such as text advertisements or image labels), web pages, or full text documents (e.g. technical articles).
