ABSTRACT
Text-based search engines are widely used to find files in the Internet. However, the users require to understand contexts existing in files and notice appropriate keywords even if the users do not have deep insights of the topic. In addition, text-based search engines require exhaustive search to make keyword indexes. This paper proposes the concept of catalogue that represents relations among files based on grouping and associating by a directed graph. Grouping of files by a catalogue without any text label lets us notice some relations represented by the catalogue. Moreover, a directed graph within a catalogue which associates files can express more detailed relations. We design catalogue system that stores and shares catalogues globally in a distributed and autonomous way. Generalized graph expression of catalogues shared over the Internet bridges any owners, types, and fields of files as long as the files share a same relation. Various services such as digital museums and digital archives are expected to work on top of the shared catalogues.

The ncsu catalog research testbed: a tool for evaluating faceted library catalog interfaces
JCDL '08: Proceedings of the 8th ACM/IEEE-CS joint conference on Digital librariesMany libraries have recently been devoting significant efforts to modernizing their library catalog web interfaces. One popular approach is to create a faceted search interface to the library catalog. Faceted search interfaces can be complex, requiring ...
FindAll: a local search engine for mobile phones
CoNEXT '12: Proceedings of the 8th international conference on Emerging networking experiments and technologiesWe present the design and evaluation of FindAll, a local search engine that lets users search and retrieve web pages, even in the absence of connectivity. Our user study with 23 users show that mobile users often search for web pages that they have ...
Finding a catalog: generating analytical catalog records from well-structured digital texts
JCDL '05: Proceedings of the 5th ACM/IEEE-CS joint conference on Digital librariesOne of the criticisms library users often make of catalogs is that they rarely include information below the bibliographic level. It is generally impossible to search a catalog for the titles and subjects of particular chapters or volumes. There has ...
