CONTEXTUALIZED SENTIMENT TEXT ANALYSIS VOCABULARY GENERATION

摘要

In techniques for contextualized sentiment text analysis vocabulary generation, a contextual analysis application is implemented to receive input data derived from rated product or service reviews. Each of the domain-specific reviews across multiple categories include a rating that is associated with expressed sentiments about a subject within a rated review. The contextual analysis application determines categories of the subjects of the rated reviews, and then generates a sentiment score for a term that is an expressed sentiment in a rated review. The sentiment score is generated based in part on a context of the term as it pertains to the category and rating of the rated review. The contextual analysis application is implemented to then determine a polarity of a term-category pair based on the sentiment score, and generate a contextualized sentiment vocabulary for all of the term-category pairs of the expressed sentiments about the subjects of the rated reviews.
