The invention relates to a traveling domain knowledge map construction method and system, and belongs to the field of Web mining and intelligent information processing. Travelling domain knowledge map construction tasks include an entity attribute knowledge expansion subtask and an entity attribute value fusion subtask. By adopting a mixed entity attribute knowledge expansion method, an entity attribute knowledge expansion algorithm based on a lexical field, supervised learning, pattern matching and search engine questions and answers is integrated. For the entity attribute knowledge expansion subtask, a multi-value attribute value fusion method based on source credibility, a fixed pattern single-value attribute value fusion method based on content credibility and a non-fixed pattern attribute value fusion method based on learning ranking are adopted. The structured travelling domain entity knowledge base is constructed, traveling domain entity attribute and attribute value knowledge is accurately expressed, the traveling domain knowledge obtaining efficiency is improved, and the wide application prospect is achieved.
