Ubiquitous Metadata Scouter – Ontology Brings Blogs Outside

In this paper, we introduce a service where ontology summarizes blogs to get useful in the real stores. In ubiquitous computing environment, it would be desired for users to bind their real world situation and useful information on the Internet. However, the current typical device for ubiquitous computing like a cellular phone has a small display, limited operations, and narrow-band network. Therefore, semantics use to extract only the necessary information and services is for the ubiquitous computing. Ubiquitous Metadata Scouter is for the user to scan products barcodes by cameras of cellular phones. It gets the corresponding metadata to the product from the Internet, and collect the related blogs. Then, it analyzes the contents of each blog referring ontologies, and indicates the total reputation. Also, it shows other related products which are much talked about. This paper illustrates each function of this service and our public experiment at the real consumer electronics store and book store in Tokyo since March 2006. It would provide an instant benefit as a semantics usecase in the ubiquitous computing.
