An Intelligent Classification and Search Method for SMS Based on Improved Bayesian Classification

Abstract

The invention discloses an intelligent short message classification and searching method based on improved Bayesian classification. The method comprises the steps that (1) a feature word list used for classifying short messages is loaded in a cell phone, and the importance value of each feature word in each predefined category is recorded; (2) short messages are read from the short message database of the cell phone, each short message d is subjected to word segmentation processing, and feature words of the short message d are obtained; (3) the probability P(Ci|d) of the short message d belonging to the category Ci is computed through the Bayesian classification algorithm according to the feature word list, and the category Ci with the maximum P(Ci|d) is used as the final classification result of the short message d. Compared with the prior art, the intelligent short message classification and searching method based on improved Bayesian classification realizes more accurate feature description of short message texts and obtains better classification effect.

Description

technical field [0001] The invention relates to a classification method and a search method, in particular to a short message intelligent classification and search method based on improved Bayesian classification, and belongs to the technical field of computer software. Background technique [0002] In today's highly developed information technology, people's communication has become faster and more frequent. In the field of mobile communication, SMS occupies an important position in people's life by virtue of its unique advantages. It can be said that text messages record every detail of people's lives. A date, a chat, an event notification, and a birthday wish are all recorded by text messages. For busy modern people, they no longer have time to record the trivial matters of life through diaries as usual, and text messages are their new diaries in the information age. [0003] However, today's mobile phone SMS management software seems to be full of beautiful things, but ...

Problems solved by technology

[0003] However, today's mobile phone SMS management software seems to be full of beautiful things, but in fact they are similar. Basically, they are simple and non-intelligent management that classifies the SMS with the characteristics of contacts and displays them in time order, which leads to people's SMS. A timeline instead of a diary, because no one puts their work diary and emotional diary together

[0004] The core of the intelligent management of short messages is to be able to accurately classify short messages. However, it is difficult to classify normal user short messages, which is mainly reflected in the fact that the text is too short: because the text of short messages is very short, this leads to many and scattered feature values. It is very not obvious, and it is difficult for many classification algorithms to achieve the expected effect in the face of this situation

[0005] At present, more and more commercial companies at home and abroad are focusing on the mobile platform. Although the research on natural language processing and text classification has been relatively mature, it is still immature to apply it to the intelligent management of short messages. This kind of difficulty Sex is shaped by the nature of texting
