Abstract: A method and an apparatus for aggregating similar terms are provided by the embodiments of the present disclosure. The method includes extracting a plurality of candidate terms having a same term property from historical labeled data of network items; separately extracting associated terms that are adjacent to the candidate terms and have term properties associated therewith from the historical labeled data; and aggregating the plurality of candidate terms based on similarity degrees of the associated terms, and labeling thereof as synonyms. Based on the embodiments of the present disclosure, similar relationships among candidate terms can be mined, and classification of synonyms can be effectively performed for unstructured and non-standardized review terms related to electronic commerce.
