The data retrieval and sorting method and system using keyword input in logical operation input table

摘要

According to the present invention, unlike a web information provider-driven search method that generally provides a search result in an existing web portal (for example, a job portal), a keyword selected by a user or directly inputted into a logical operation input table and each keyword Provides input factors (importance, matching constants), output factors (frequency), and matching result values (match count, total frequency, matching combination values) for each candidate searched by a predetermined rank and logical combinations set in the table. A user-oriented search method that induces a user to change (modify) a keyword and an input argument, check the result accordingly, and then modify the search result again, and induce a user to search for an optimal matching result. System. The present invention provides a data retrieval and sorting method using a keyword entered in a logical operation input table, and a system thereof. The system may include an item classification unit configured to interpret keywords classified by a user through a logical operation input table and classify the keywords according to items, and to interpret the meanings of the keywords and convert them into predetermined appropriate terms. A phrase processing unit for generating a Boolean function composed of a combination of the keywords, a calculation processing unit for performing the operation of the Boolean function on data stored in web information or a database or a file system, and a result of the processing result of the calculation processing unit. A matching output unit for outputting and a central processing unit controlling the operation of providing the logical operation input table to the user, and controlling the operations of the item classification unit, the syntax conversion unit, the operation processing unit, and the matching output unit. do.
