Chinese word entry index compression method based on mobile terminal and mobile terminal

Abstract

The embodiment of the invention discloses a Chinese word entry index compression method based on a mobile terminal and the mobile terminal. The quantity of data stored in an ROM or an SD of the mobile terminal is greatly reduced, so that the processing speed of subsequent index retrieving is increased, and the technical problem that for a traditional database index scheme, due to the fact that Chinese word entries are not optimized, the efficiency is low when information of word entries containing partial characters or words is retrieved is solved. The Chinese word entry index compression method based on the mobile terminal comprises the steps that all classified word groups are associated according to keywords, and a corresponding associated word group list is established; the associated word group list is subjected to coding processing based on a position relationship of the keywords in the word groups, and a corresponding compression character string is generated; the compression character string is stored.

Description

technical field [0001] The invention relates to the technical field of data mining, in particular to a mobile terminal-based Chinese entry index compression method and the mobile terminal. Background technique [0002] An index is a structure that sorts the values ​​of one or more columns in a database table (for example, the name (name) column of the employee table). If you want to find a specific employee by his or her last name, an index can help you get the information faster than searching all the rows in the table. The database index is like the table of contents in front of a book, which can speed up the query speed of the database. Indexes are divided into clustered indexes and non-clustered indexes. Clustered indexes are ordered according to the physical location of data storage, while non-clustered indexes are different; clustered indexes can improve the speed of multi-row retrieval, while Nonclustered indexes are fast for single row retrieval. According to the ...
