Information analysis technology for Universal Communication

摘要

The Internet functions as a social infrastructure and stores a huge amount of information. People use the Internet whenever they need information. The primary role of the Internet is changing from that of digital content sharing to that of knowledge sharing. NICT Knowledge Clustered Group is researching and developing information analysis technology for “Universal Communication”. In order to realize universal communications, we have to overcome several barriers. Information analysis is an essential technology to overcome a barrier of “Information Quality”. The overabundance that makes it difficult to extract the most useful information from the Internet is called the information explosion. The amount of consumer generating media (CGM) is increasing particularly rapidly, but the content may be neither valuable nor trusted. Ordinary web search engines cannot evaluate the content. However, if we can evaluate the credibility of information, credible digital content will be as easily accessed knowledge is on the Internet. We believe that information analysis technology to find higher quality information on Web content enables us to overcome a barrier of “Information Quality”.Research project of NICT Knowledge Clustered Group focuses on analysis of information credibility criteria and development of a knowledge cluster system. The former project addresses the information credibility criteria of web content using natural language processing (NLP) technology. The latter project aims to develop a knowledge cluster system that manages knowledge on enormous numbers of sites.
