Example Embodiment

[0043] For the convenience of description, we use examples to describe how to answer who or who or

[0044] Questions guided by when (when) or where (where), answer the questions guided by what (what) through the information graph, answer the questions guided by how (how) through the knowledge graph, answer the why (why) through the wisdom graph The problem of booting.

[0045] The specific implementation plan is:

[0046] (1) Build a library of problem patterns. The present invention categorizes the questions into four modes after word segmentation and part-of-speech tagging, which are respectively the questions guided by who, when, or where, and by what. The question, the question guided by how and the question guided by why;

[0047] (2) Calculate the semantic similarity between the question words in the question and the question words in the question word list, and determine the mode of the question;

[0048] (3) Choose which map to traverse according to the problem mode:

[0049]...

Abstract

The invention discloses a classified question-answering system design method based on an associated framework of a data atlas, an information atlas, a knowledge atlas and an intelligent atlas, aims to answer a text question which is put forward by a user in a natural language through atlas query and traversal, and belongs to the technical cross field of distributed calculation and software engineering science. The problems which are put forward by the user can be classified according to different question words, questions guided by question words including who, when, where and the like can traverse and search answers on the data atlas, the questions guided by what can search answers on an information atlas, the questions guided by how search answers on the knowledge atlas, and questions guided by why can search questions on the intelligent atlas. In addition, 5W questions are subjected to overlapping and migration on an aspect of semantic expression, and problems can be correspondingly converted.

Description

technical field [0001] The present invention is a design method of classification question answering system based on data map, information map, knowledge map and wisdom map correlation architecture, mainly used to answer text questions raised by users using natural language by querying and traversing maps, and belongs to distributed computing and software Interdisciplinary fields of engineering and technology. Background technique [0002] The knowledge map was officially proposed by Google on May 17, 2012. Its original intention was to improve the capabilities of search engines and enhance users' search quality and search experience. At present, with the continuous development of intelligent information service applications, knowledge graphs have been widely used in intelligent search, intelligent question and answer, personalized recommendation and other fields. Especially in intelligent search, the user's search request is no longer limited to simple keyword matching, an...
