Implementation of TV-program Navigation System Using a Topic Extraction Agent

Abstract

To some extent, we can easily know the topics of the world thourgh TV programs. On the other hand, it is not easy for many users to find the TV programs that offer unexpected interesting information. Then we constructed a “topic extraction agent” which extracts keywords that compose some topics from the texts of electronic program guides (EPGs) and shows the keywords to a user. We also implemented a TV-program navigation system by using this topic extraction agent. In this paper, we describe the architecture of this agent and consider the precision of keyword extraction and that of TV-program retrieval.
