Abstract
The present disclosure includes a device for constructing an intelligent knowledge base. The device comprises: a preset knowledge subject obtaining unit to obtain from a subject domain database preset knowledge subjects each comprising a standard question and an extended question; a receiving unit to receive an initial request message; a calculation unit to perform a semantic similarity calculation on the initial request message and the preset knowledge subjects to obtain a plurality of semantic similarity calculation results; a determination unit to determine whether a largest semantic similarity calculation result is greater than a similarity threshold value; and a storing unit to: when the largest semantic similarity calculation result is greater than the similarity threshold value, store into the intelligent knowledge base the initial request message, and a standard question and an extended question of a preset knowledge subject corresponding to the largest semantic similarity calculation result.
