Abstract

The invention discloses an intelligent question and answer method and device, a knowledge base optimizing method and device and an intelligent knowledge base. The intelligent question and answer method comprises the steps that a knowledge base is provided, wherein the knowledge base comprises a plurality of knowledge points, each knowledge point comprises an answer and one or more questions, semantic expressions are adopted for at least part of the questions, and the semantic expressions comprise parts of speeches; input information of a user is obtained; semantic similarity calculation is carried out on the input information and the questions in the knowledge points, and when the maximum semantic similarity value obtained through calculation is larger than a preset threshold value, the answer in the knowledge point corresponding to the maximum semantic similarity value is sent to the user, wherein the knowledge base comprises fuzzy knowledge points, in the calculation process of semantic similarity, the semantic similarity of the fuzzy knowledge points and the input information is calculated only when the maximum semantic similarity value of the knowledge points except the fuzzy knowledge points and the input information is smaller than the preset threshold value, and answers in the fuzzy knowledge points are sent to the user when the semantic similarity of the fuzzy knowledge points and the input information is larger than the preset threshold value.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an intelligent question answering method and device, a knowledge base optimization method and device, and an intelligent knowledge base. Background technique [0002] In the question answering system, the knowledge base plays a crucial role. The knowledge base includes multiple knowledge points, and each knowledge point includes an answer, a standard question and / or multiple extended questions corresponding to the standard question. Standard questions and extended questions can be in the form of ordinary questions or semantic expressions, which are distinguished according to whether they include parts of speech. Semantic expressions include parts of speech. Parts of speech are divided according to the semantics of words. A group of related words are organized together to form a tree-structured part-of-speech library. Any non-leaf node in this tree-like structure is is called a...
