Knowledge base fusion method for encyclopedia websites

Abstract

The invention provides a knowledge base fusion method for encyclopedia websites. The knowledge base fusion method is used for fusing knowledge cards (intebox) of Baidu encyclopedia, interactive encyclopedia and Chinese Wikipedia with the largest influence at present. The method comprises the following steps: step 1, acquiring a query result of an encyclopedia website about the same entity and preprocessing the query result; step 2, establishing a mapping relationship for entities in the encyclopedia website by integrating concept similarity, attribute similarity and context similarity characteristics; step 3, performing attribute alignment on the knowledge cards of the entities with the established mapping relationship by means of an external dictionary; step 4, designing a single truth value discovery scheme and a multi-truth value discovery scheme for attributes with conflict attribute values according to whether the attribute values are single-value type and multi-value type; and step 5, outputting the fused attribute-attribute value pair. And finally redundant high-reliability entity-related attribute-attribute value pairs of the three encyclopedia knowledge cards are obtained.

Description

technical field [0001] The invention relates to knowledge base fusion, in particular to a knowledge base fusion method for encyclopedia websites. Background technique [0002] The era of big data in which data is king has arrived, and data management and knowledge engineering are also playing an increasingly important role. The knowledge base plays an important supporting role in applications such as search, machine translation, and intelligent question answering. In order to efficiently manage and acquire the required knowledge, many scholars at home and abroad have invested in the research of knowledge base construction, such as foreign YAGO, DBpedia, Freebase, Nell , Knowledge Vault, domestic CN-DBpedia, Zhishi.me, XLORE, etc. [0003] At present, the construction of knowledge bases has achieved fruitful results, but most of these completed knowledge bases are scattered and independent, and their respective knowledge architectures and descriptions are different. For exa...
