Power keyword segmentation based data retrieval method and device

Abstract

The invention discloses a power keyword segmentation based data retrieval method and device. The method includes the steps of S01, inputting a keyword in a to-be-inputted textbox on a page; S02, according to the inputted keyword, structuring single searching, recording and parsing structural objects and segmenting the keyword into two or more keywords to form a keyword set; S03, determining matching relations of the keywords in the keyword set and a word bank and processing the keywords, wherein the matching relations include complete matching, incomplete matching and non-matching; S04, sorting all the keywords stored in the searching, recording and parsing structural objects according to the size of weight and filtering the keywords to be displayed on the page; S05, outputting data after assembling SQL (structured query language) and searching a database. With the method and device, searching efficiency can be greatly improved, and searching of the power keywords is facilitated.

Description

technical field [0001] The invention relates to a keyword retrieval method, in particular to a data retrieval method and device based on power keyword segmentation. Background technique [0002] For Chinese search engines, Chinese word segmentation is one of its core technologies. Chinese word segmentation technology belongs to the category of natural language processing technology, and its application is not limited to Chinese search engines, it is also a major component of Chinese information processing. Chinese information processing is a process in which computers process and process Chinese information such as sound, form, and meaning. A comprehensive discipline related to disciplines. The basic methods of Chinese word segmentation include the following three: word segmentation methods based on string matching, word segmentation methods based on understanding, and word segmentation methods based on statistics. [0003] The word segmentation method based on string mat...

Problems solved by technology

Search engines on the Internet use search engine crawler technology to crawl new, publicly accessible web pages, pictures and document resources from the Internet according to certain strategies and specific computer programs, and organize and process the information. , to provide users with retrieval services, and display the information related to user retrieval to the user's system. Its processing object is the Internet webpage, and the ledger data and monitoring data of the power grid equipment panoramic monitoring platform are stored in a large amount in the database. Directly It is impossible to search the full text of the device or device type that the user cares about with the search engine technology on the Internet

[0006] The panoramic monitoring platform of power grid equipment is a business scenario that spans multiple links of transmission, transformation, distribution, and utilization, and integrates various business subsystems such as smart grid distribution automation, power quality monitoring, power consumption information collection, status monitoring, and production management systems. Information, forming a multi-dimensional, all-round, and three-dimensional provincial unified monitoring platform that integrates comprehensive business, data information, and visualization technology. The amount of data covered is huge. The simple combination of menus, although the query speed is fast, but the user needs to remember the menu level, the user has a large memory burden and the operation is more cumbersome

Or store all the equipment or even all monitoring system data in one table and only use one menu query. Although the operation is relatively simple, the data query speed is very slow
