Abstract

The invention provides an EPG information analyzing method and system. The method comprises following steps: learning by a conditional random field model basing on multiple pieces of EPG information and corresponding type information, thus obtaining an analyzing model related to the features of the EPG information; extracting the features of the current EPG information; carrying out conditional random field analysis by using the analyzing model so as to obtain the type information corresponding to the current EPG information. According to the EPG information analyzing method and system provided by the invention, the analyzing efficiency is high; the analyzing accuracy is high; the single character accuracy reaches 99.9 %; and the single sentence accuracy reaches 98.5 %.

Description

technical field [0001] The invention belongs to the technical field of radio and television broadcasting systems, and in particular relates to an EPG information analysis method and system. Background technique [0002] An electronic program guide (EPG for short) has become an important symbol of digital television, and is a portal for viewers to enter digital television and interactive network television (IPTV for short). The EPG system can provide users with an easy-to-use, friendly interface, and fast access to the programs they care about. It not only enables users to find their favorite programs conveniently, but also can see the upcoming programs on one or more channels or even all channels. program played. [0003] The relevant program information processed by the EPG system is called EPG information, which includes the following types of information: program name, program subtitle, column name, program classification, episode number and total episode number, etc. D...
