In this paper I examine about combining, sharing and constructing geographical knowledge on the Web with an E-learning system using land use maps developed by myself. A learner can represent geographical knowledge on a map as a legend data and a mesh map data on the system. By using this format, combination and reuse of mesh data, from personal level, to class level and then to inter-school level, are possible. Each mesh data is managed by the system. RDF and RDF schema are used for knowledge representation in metadata, mesh data and legend data. This system was implemented through a joint research with the Geographical Survey Institute, Government of Japan.

With increasing the Web information, users got necessity to have attention for that. Ability of human information processing has a limit, and web search ranking results is a fundamental problem in information retrieval. Recently personalization and adaptation of Web data have become very important issues. These techniques use user's behavior, and clarify user's context. First, we introduce researches about personalization of Web data and compared in their features. We also discuss about improvement ordering of web search ranking results incorporating user's behavior.

In this paper, we introduce our cognitive approach about the information seeking on the Web. First, we investigated how people find information into web space by using protocol analysis. Second, we applied experimental findings of our study to constructing learning environments that help students to acquire information search skills. Finally, we try to apply our cognitive studies to create a computational model of information seeking on the Web and developing evaluation indicators for information retrieval experiments.
