Abstract:
The present invention relates to a system and method for semantic level sentiment analysis. The system (100) comprises of a graph generator component (10), a semantic sentiment analyser component (20), a sentiment processor component (30), a sentiment dictionary (40), a sentiment taxonomy (50), a semantic sentiment patterns repository (60) and a propagation rules repository (70). The system (100) accepts text data as input and analyses sentiment in the text. The method enables semantically valid sentiment in terms of the entire text as well as the individual entities in the text.
Abstract:
The present invention provides a system for extracting concept and named-entities from a text-containing document. An entity recognition eagine (102) is provided to process an entity with a Rule-based Named-Entity Recognition (NER) (122), a Natural-Language-Processing (NLP) based NER (124), and a knowledge-based NER (126). The NERs are further scored and weighted, wherein the highest weighted score will be taken. A method thereof is also provided.
