Recently Web API (Application Programming Interface) is widely utilized for the service interfaces in enterprise applications. In this article, the possibility of applying Web API to electronic commerce, especially to EDI (Electronic Data Interchange), is discussed. We propose architecture called “Open EDI” as a platform for such activities. And the notation of “Cloud_Object” is introduced that is...
Recently, in line with increased hardware performance, resources for individual PCs have increased. These resources are however, seldom fully utilized, resulting in many free or idle resources. We are currently investigating implementing a full grid on windows PCs using virtual machines. This study aims to utilize idle resources on windows PCs within a Linux grid using virtual machines (virtual grid)...
A method is described for discovering coordinate terms, such as "Honda'' and "Nissan,'' for a given term, such as "Toyota,'' as well as their common topic terms, from the query logs of a Web search engine. Coordinate terms are good candidates for use in making comparisons. A HITS-based algorithm is applied to a bipartite graph between coordinate term candidates and co-occurrence patterns...
Concept hierarchy knowledge, such as hyponymy and meronymy, is very important for various natural language processing systems. While WordNet and Wikipedia are being manually constructed and maintained as lexical ontologies, many researchers have tackled how to extract concept hierarchies from very large corpora of text documents such as the Web not manually but automatically. However, their methods...
This paper presents priority areas where improvements are needed in the dependability of financial information systems by analyzing the current state of dependability for such systems. Focusing on accidents in financial information systems, which play an important role in the infrastructure of our information society, we first selected widely accident articles from four national major newspapers in...
Certain data repositories provide search functionality for temporally ordered data. News archive search or blog search are examples of search interfaces that allow issuing structured queries composed of arbitrary terms and selected time constraints for performing temporal search. However, extracting aggregated knowledge such as detecting the evolution of objects or their relationships through these...
We propose a way to wrap both Web information spaces and pervasive data environments by providing a uniform view of databases. Search result of search engines and processing results of several Web search services are wrapped and viewed as "virtual tables" of relational databases. The device manipulation environment and data captured by those devices are also viewed as "virtual tables...
A method is proposed for viewing broadcast content that converts TV programs into Web content and integrates the results with complementary information retrieved using the Internet. Converting the programs into Web pages enables the programs to be skimmed over to get an overview and for particular scenes to be easily explored. Integrating complementary information enables the programs to be viewed...
This paper proposes shared control in Internet-based remote stabilization for nonlinear systems. This paper consists of two parts. The first part addresses the basis of Internet-based remote stabilization for a single nonlinear system with time-varying delay. We derive a delay dependent sufficient condition for ensuring the stability of Takagi-Sugeno (T-S) fuzzy models with time-varying delays that...
Adaptivity and context awareness are becoming more important in recent Web systems. We developed a prototype adaptive system called the "Personal Digital Librarian" (PDL). The PDL is a book recommendation and management system. The PDL user can obtain information on books appropriate to the user's interests. In addition, we have also improved the PDL to deliver book information appropriate...
