Keyword based evaluation expert intelligent search and recommendation method

Abstract

The invention discloses a keyword based evaluation expert intelligent search and recommendation method. The keyword based evaluation expert intelligent search and recommendation method specifically comprises step 1, segmenting an expert information main text into substring sequences, performing ICTCLAS word segmentation of Chinese academy of sciences and performing stop word filtering on the result of the word segmentation to obtain the word collection; step 2, extracting feature words of the expert information according to fields; step 3, building an expert knowledge representation model based on the fields and the weight of the feature words and establishing an expert information index database; step 4, performing automatic prompting according to a search term thesaurus when a user inputs keywords and meanwhile performing real-time update on the search term thesaurus through a search term counter; step 5, calculating the search relevance between the keywords and the expert information based on the semantic information and the like; step 6, listing relevant experts from high to low according to the matching degree. According to the keyword based evaluation expert intelligent search and recommendation method, the intelligent full-text search and recommendation of the expert information can be achieved through the keyword input and accordingly the experts which are matched with a pended science and technology project can be searched out accurately.

Description

technical field [0001] The invention belongs to the technical field of information retrieval, and in particular relates to a keyword-based intelligent retrieval and recommendation method for evaluation experts, which is used for retrieving evaluation experts for scientific and technological projects. Background technique [0002] With the rapid popularization of science and technology project declaration management system in our country, the evaluation work of science and technology projects has developed from the previous centralized meeting mode to the current network mode. The evaluation experts will evaluate the project application based on the domain knowledge and the funding standards of the funding agency, and the funding agency will decide whether to fund or not based on the evaluation results of the evaluation experts. The scale of science and technology project management system is getting larger and larger, forming a large amount of expert database information. S...

Problems solved by technology

When calculating the retrieval correlation, it is not considered that each field of expert information has different importance; at the same time, because there is no special index library, in the case of a huge amount of expert information, the results cannot be retrieved quickly, and the results cannot be searched according to the degree of relevance. to sort

In addition, the prior art mostly lacks the intelligent association prompt function when inputting keywords

These will lead to low recall and precision rates of retrieval results, which limits the ability of automatic analysis and intelligent processing in the field of scientific and technological project review expert retrieval, and directly restricts the social service ability of scientific and technological project review work

Today's general-purpose full-text retrieval technology has been applied in many fields, which can effectively alleviate the above problems, but it is rarely used in the field of expert information
