    The purpose of this paper is to provide a historical overview of evaluation methods in information retrieval research, and to point out issues to be explored for enhancing the evaluation. First, Cranfield test and TREC are described as an epochal retrieval experiment, which provides a standard framework of the evaluation. Second, metrics used for evaluating search results in experiments are discussed. In particular, average precision developed for evaluating ranked output is explained in detail, and some problems in using this metric are clarified. Finally, various interpretations of ‘relevance’ concept as a measure for evaluating search results are discussed, and the difference between objective and subjective interpretations of relevance is explored.

  • SciNetS, an information platform for a virtual laboratory center and “Science Simulator” developed using a social approach to knowledge sharing

    In recent years life sciences have become very “dependent on database infrastructures”, because many people need to study data that they have requested to be available as web resources. Given such circumstances, RIKEN has been developing a next-generation informatics infrastructure called SciNetS (the Scientists' Networking System). SciNetS aims to integrate scientists' activities, measurement devices, computer resources, and databases distributed on the web, so that SciNetS not only helps scientists to solve various scientific questions, but also provides the way for people in society to use the data for various purposes. In this paper we introduce an overview of our development of the SciNetS technology, which we hope will open the door to the creation of a new “web phenomics”, a web science for studying social phenomes. This includes the sum total of human's phenotypic characteristics, combined with expression that may be influenced by its environment including society and culture.

    Developed for analyzing and visualizing complex networks in bioinformatics and other fields, Cytoscape has found wide application today in social networks, Semantic Web and many other areas. The tool can be considered to work properly on patent information as well. Despite the potential usefulness, Cytoscpae has low visibility especially in Japan and has no specific examples of application in patent information analysis on a global basis at this time. This paper shows practical procedures on using Cytoscape effectively in patent information analysis. Providing some case examples, it demonstrates a wide array of visualization functions of Cytospcape and techniques to extract nodes with its network analysis functionality. It also gives some suggestions on a macro analysis using text mining approach including Cytoscape.
