Embodiment Construction
[0055] The embodiment of the present invention provides a method for compressing a Chinese term index based on a mobile terminal and the mobile terminal, which realizes that the amount of data stored in the ROM or SD of the mobile terminal is greatly reduced, thereby increasing the processing speed of subsequent index retrieval. The traditional database indexing scheme is not optimized for Chinese terms, which causes the technical problem of low efficiency when searching for the information of the terms containing some characters or words.
[0056] ROM: short for Read-Only Memory, a solid-state semiconductor memory that can only read data stored in advance. Its characteristic is that once the data is stored, it cannot be changed or deleted. It is usually used in electronic or computer systems that do not need to change data frequently, and the data will not disappear because the power is turned off. Mobile devices such as mobile phones and tablet computers will use this kind of ...

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 method for compressing Chinese term index based on a mobile terminal and a 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 column of the employee table). If you want to find a particular employee by his or her last name, the index helps to obtain information faster than searching all 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, and Non-clustered index is very fast for single row retrieval. According to the function of...
