Problems solved by technology

However, the search formula generated by this method is completely opaque to the user, so the result is unpredictable; secondly, the logic of "or" is usually used to connect the expansion words, which can only improve the performance of the search results to a limited extent. There is no effective and quick evaluation method for the results, and searchers need to browse one by one; again, the generated search formula cannot be reused. If the user wants to retrieve this type of data on different data sets, he needs to rebuild the search formula

Abstract

The invention discloses an interactive search generation method and system. The method includes: after receiving a user-entered primary search, acquiring a primary search document set corresponding to the primary search; subjecting the primary search document set to theme clustering, and acquiring primary search document subsets in one-to-one correspondence with themes; extracting theme words from the primary search document subsets; providing users with the theme words and corresponding themes, and reminding the users to determine secondary searches related to the corresponding themes, with the theme words. The interactive search generation method and system can assist users in generating complex searches and help search professionals in the professional search field generate more accurate searches.

Description

technical field [0001] The invention relates to the field of text retrieval, in particular to an interactive retrieval formula generation method and system. Background technique [0002] With the rapid growth of various types of information in modern society and the continuous improvement of storage technology, it is becoming more and more difficult to quickly and effectively obtain useful information from massive data, and a large amount of data cannot be effectively used. Retrieval is a technical means to achieve rapid acquisition of useful information in massive data. It receives the user's search input and searches the database for content related to the search. The search formula is the search word string for understanding and operation, including at least keywords. For complex searches, it usually includes logical operators, search instructions (search syntax), etc., where keywords are the main body of the search formula, logical operators and search terms Instruction...
