Abstract

The invention discloses a text search method and system based on a fuzzy language approximate concept lattice. The method comprises the following steps: acquiring a plurality of evaluation language values in a house renting field; according to the houses, the house attributes and the relationship between the houses and the house attributes, constructing a house renting field fuzzy language data set; generating a house renting field fuzzy language approximate concept; generating a house renting field fuzzy language approximate concept lattice; obtaining a complemented house renting field fuzzy language approximation concept; according to the complemented house renting field fuzzy language approximate concept and the house renting field fuzzy language approximate concept lattice, obtaining the complemented house renting field fuzzy language approximate concept lattice; and obtaining a to-be-searched house attribute in the house renting field, inputting the to-be-searched house attribute into the complemented fuzzy language approximate concept lattice in the house renting field, and outputting a search result. By means of the complemented fuzzy language approximate concept lattice, the problem that part of evaluation information in the house renting field is incomplete can be solved, the incomplete evaluation information is processed, and the search range is narrowed.

Description

technical field [0001] The invention relates to the technical fields of data mining and intelligent information processing, in particular to a text search method and system based on a fuzzy language approximate concept lattice. Background technique [0002] The statements in this section merely mention the background technology related to the present invention, and do not necessarily constitute the prior art. [0003] At present, concept lattice, as an effective data analysis tool, has been widely used in information retrieval, software engineering, recommendation system, knowledge discovery and other fields. The concept lattice can be used to discover hidden concepts and the relationship between concepts, and the concept lattice can formalize the concept and represent all concepts through symbols. However, due to the completeness and accuracy of the classical concept lattice, there will be certain limitations in practical applications. In order to represent incomplete info...
