Abstract: In techniques for contextual sentiment text analysis, a sentiment analysis application is implemented to receive sentences as text data, and each of the sentences can include one or more sentiments about a subject of the sentence. The text data can be received as part-of-speech information that includes noun expressions, verb expressions, and tagged parts-of-speech of the sentences. The sentiment analysis application is implemented to analyze the text data to identify the sentiment about the subject of a sentence, and determine a context of the sentiment as the sentiment pertains to a topic category of the subject in the sentence, where the topic category of the subject is determined based on text categorization of the text data. The sentiment analysis application can also determine whether the sentiment is positive about the subject or negative about the subject based on the context of the sentiment within the topic category of the subject.
