| Abstract: | Mining the customer reviews accurately in commercial websites has significant meaning in effective recommendation for trade company. A kind of novel algorithm—Customer Review Extraction (CRE) was put forward in this paper. CRE iteratively segments page and calculate the information entropy to automatically discover and extract the reviews. The experimental result has proved that the algorithm has higher recall and precision. |
