Abstract

A method of multi-dimensional query based extraction of polarity-aware content from a plurality of documents. An input query tuple comprising: at least one keyword, polarity, and quantification of polarity corresponding to a polarity score is received from a user via an interface. A search of metadata of indexed documents based on the input query tuple is conducted to identify documents which satisfy at least some of the input query tuple. For each document which satisfies at least some of the input query tuple from the user, keywords, polarity associated with the keywords, and excerpts of each of the documents including the keywords and text containing polarity context associated with the keywords are extracted and for each document which satisfies at least some of the input of the input query tuple, the query results to the user via the user interface are outputted.
