发明名称 SIGNAL PROCESSING APPROACH TO SENTIMENT ANALYSIS FOR ENTITIES IN DOCUMENTS
摘要 A document can be processed to provide sentiment values for phrases in the document. The sequence of sentiment values associated with the sequence of phrases in a document can be handled as if they were a sampled discrete time signal. For phrases which have been identified as entities, a filtering operation can be applied to the sequence of sentiment values around each entity to determine a sentiment value for the entity.
