SYSTEM AND METHOD FOR PROVIDING RECOMMENDATIONS BASED ON INFORMATION EXTRACTED FROM REVIEWERS' COMMENTS

摘要

A recommendation method includes receiving a user's review of an item that includes a textual comment. Deficient features of the reviewed item are identified from the text by applying a set of extraction patterns. Each pattern is satisfied when a term in the text, which is associated in a structured terminology with one of a predefined set of features, is in a syntactic relation with another term in the text, such as a polar adjective or expression of a wish or a lack. When such a pattern is satisfied, the corresponding feature is considered a deficient feature. Feature attributes of the reviewed item are compared with corresponding feature attributes of a set of items to identify any improved items whose attribute for the deficient feature is better than that for the reviewed item. The improved item or items can be recommended to the user or to others reading the review.
