Embodiment Construction

[0043] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0044] Such as figure 1 The shown data search system based on semantic analysis includes a sentence receiving unit, a semantic analysis unit and a search unit. The statement receiving unit receives the query statement input by the user, and transmits the query statement to the semantic analysis unit; the semantic analysis unit analyzes the query statement, determines the geographical scope of the search and the search keyword; the search unit combines the search scope and the search keyword search.

[0045]The semantic analysis unit in this embodiment includes a word segmentation thesaurus, a geographical noun base and a phrase thesaurus. For the query sentence input by the user, the word segmentation thesaurus is ...

Abstract

The invention relates to a data searching method and system based on semantic analysis, and belongs to the technical field of information searching. The method comprises the steps that keywords input by a user are divided into words with different parts of speech through a word dividing library, for results after the words are divided, geographical positions to be searched can be determined according to a geographical noun library if the parts of the speech are geographical names, otherwise matching is carried out by entering a phrase word library, query is further carried out based on keywords corresponding to the matched record, and words input by the user are regarded as the keywords of the inquire if matching is failed. The data searching method and system based on the semantic analysis carries out the semantic analysis based on a large number of behaviors of the user, can carry out good analysis on non-concrete nouns, verb-object phrases, modification phases and other vocabularies with generalization properties, can automatically select new words needing to be put into a library at the same time, is few in searching repeated process, high in searching efficiency and relatively precise in researching result and can meet demands of clients.

Description

technical field [0001] The invention relates to a data search method and system, in particular to a semantic analysis-based data search method and system. Background technique [0002] Most of the searches in the prior art use full-text search, that is, to find records containing keywords by using input keywords as search objects. Full-text indexing only deals with text, not semantics. When the search content entered by the user is not a very clear keyword, the output result is often inaccurate or even not what they need at all. Only by searching twice, three times or even more times can you get the results you want. In today's era of information explosion, full-text search has gradually been unable to meet user needs, and a data search method and system with higher search efficiency and search results more in line with customer needs is needed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a data search met...
