| author: | Yoshiyuki WATASE(High Energy Accelerator Research Organization (KEK)) |
| abstract: | In recent years High Energy Physics has extended its activities on an international research level ，based on its nature of pure science as well as being supported by an continuously developing evolutionary network environment. Typical usage of the network is described here in the case of KEK Belle experiment. In particular ，the recent rapid speedup of the network such as SueprSINET is opening up a new research environment which operates as a virtual laboratory or as an open laboratory using the Grid technology on the global network. |

| abstract: | Packet classification is one of the key technologies to support differentiated services to classified flows. Combining the top-down lookup tree structure and intelligent constructing strategy of present algorithms, this paper proposes a hybrid approach to packet classification. The filter set, which is used to classify packets, are stored in the leaf chains of a special data structure, in which an index table acts as index to locate several lookup trees. Also, an evaluation formula shows the major criteria on how to build lookup trees and distribute filters to obtain satisfactory efficiency. The performance of the proposed algorithm is discussed by analytical computation and simulation. Theoretically, it has a logarithmic execution time cost with a polynomial space (storage) cost. Further, a simulation of packet classifier built on IBM Power Network Processor is performed to test its performance and do a comparison between multi-tree applied cases and the unapplied. The results show its superiority in complex filter handling and matching modes. |

| abstract: | In recent years, the demand of Web pages browsing by using mobile terminals i.e. cellular phone, PHS etc. is increasing. However it is difficult to browse Web pages by using mobile terminals, because Web pages are made for large size display of personal computers. In order to solve this problem, it is necessary to summarize Web pages. In this paper, we propose a new method of sentence extraction based on document frequency and clause length for summarizing book abstract. We compared our method with conventional sentence extraction methods based on TF-method and TFIDF-method. Experimental results show that our method improves both recall and precision. |
| 4. The Environment Money that has an Aerial Mileage Service as the Core | |
| author: | Yos h i o WATANABE(The Graduate University for Advanced Studies), Hitoshi OKADA(National Institute of Informatics) |
| abstract: | This study proposes a platform, which gives benefits to the people who use technology that restrains the emission of carbon dioxide. The platform we propose here makes it easy to evaluate and reward the acts of preserving the environment. It will promote the use of technology that will restrain emissions of carbon dioxide, thus will lead to the environmental preservation. The platform is made up of manufacturers, consumers and airline companies. It evaluates the restraint effects of the carbon dioxide emissions by the frequency of the use of the products that are equipped with the technology for that purpose. The promotion of the use of this technology will aid in preserving the atmospheric conditions. To simplify the platform's evaluation, 0.1kg restraint of the carbon dioxide emission that results from the use of such a product will be counted as a unit of 1 APE (action with preservation of the environment). This study shows a model of the platform for exchanging ape into Aerial mileage service amenity and also proposes the flow of the function that will promote its realization. |

| abstract: | Detecting and eliminating duplicate records is crucial in integrating multiple source databases. However, the task of identifying linkages between records is often costly and hard due to the lack of common record identifiers, and also the variations of notations of attributes and values with no explicit correspondences. Specifically, when dealing with large databases with long and distributed maintenance histories, highly reliable record linkage is difficult. There has also been a new and emerging aspect of the problem that is the manipulation of semi-structured data. Based on the background, we present an overview of data cleaning techniques for detecting and eliminating duplicate records in this paper. |
| 6. Comparison of Innovation Policy and Transfer of Technology from Public Institutions in Japan, France, Germany and the United Kingdom Part 1 French and Japanese Case study | |
| author: | Henri ANGELINO(Visiting Professor, National Institute of Informatics),Nigel COLLIER(Associate Professor, National Institute of Informatics) |
| abstract: | During the last 20 years many changes have been undertaken concerning the research and innovation policies in Japan and France. In France this corresponds to the "disappearance of the Colbertiste State" which culminated with the Innovation Act in 1999 and later on the implementation of the incubator policy as well as actions for facilitating seed funds, university-industry relations, seed funds for start-up, etc. Some more recent initiatives have been taken with the new "Innovation Plan" including a new status for "Business Angels", Young Innovative Companies, the Law to encourage sponsorship and creation of foundations, etc. In Japan, since 1946 Science and Technology has always been a priority but the Government adopted a new approach in the 1990's. The starting point was the S&T Basic Law in 1995 and since then many actions have been taken and Laws enacted: the First and Second S&T Basic Plan, TLO creation, Japanese Bayh-Dole Act, creation of the Council for Science and Technology Policy (CSTP), Intellectual property Law, National University Reform Bill, etc. In the case of France, results of the national annual competition on the creation of firms based on innovative technology are analyzed and the CNRS and INRIA cases are presented including the start-up procedure and results for these two major French research organizations. For Japan we analyze the TLO activities, the role of CSTP, the results obtained through all the different actions e.g. Intellectual Cluster program, the City area program the Industrial clusters, the start-up policy. We conclude that both countries are "moving the same direction", using the "same recipes" though adapting the solutions to their national context. |
