Abstract

The invention discloses a text search method and system based on fuzzy language approximation concept lattice, which can obtain several evaluation language values ​​in the field of renting houses; build fuzzy language data sets in the field of house renting according to houses, house attributes and the relationship between the two; generate house renting Domain fuzzy language approximation concept; generate rental domain fuzzy language approximation concept lattice; get completed rental domain fuzzy language approximation concept; according to the completed rental domain fuzzy language approximation concept and rental domain fuzzy language approximation concept lattice, get completion The final fuzzy language approximation concept lattice in the rental domain; obtain the housing attributes in the rental domain to be searched, input the housing attributes to be searched into the completed fuzzy language approximation concept lattice in the rental domain, and output the search results. Using the completed fuzzy language approximation concept lattice can solve the problem of incomplete evaluation information in the field of renting houses, deal with the incomplete evaluation information, and narrow the search range.

Description

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