  1. Noriko Kitani and Shuichi Yukita, “Mathematical Ontology And A software Tool For Semantic Retrieval Of Exercise Problems,” (to appear) in The International Symposium on Web and Mobile Information Services, March 2008.
    Abstract - A huge number of entrance examination questions are accumulated in databases at various educational institutions and companies in education industry. These questions are valuable resources of teaching materials at schools. However, these resources are not accessible at the semantic level, that is, we can not retrieve right data by specifying concepts or teaching goals independent of the way of presentation and terminology. Though such problems in various fields are successfully tackled by introducing ontology technologies, little is accomplished in the educational domain. In this paper, we introduce an example of ontology in the field of mathematics education and present a problem searching tool based on the ontology to prove the effectiveness of our semantic approach.
  2. Jun Futagawa and Shuichi Yukita, “S2Directory – A Framework for Object-Directory Mapping with Dynamic Implementation Injection,” (to appear) in Proceedings of the 22nd International Conference on Advanced Information Networking and Applications, March 2008.
    Abstract - Object models adopted in the object oriented software development reflect complex relations that exist between various entities in the real world. On the other hand, directory models adopted in directory service technologies map various relations into tree structures. Therefore, developing directory services by object oriented languages require writing lengthy procedures that bridge the gaps between object models and directory models. To overcome this drawback, in this paper, we propose a new technology named Object-Directory Mapping. We also present a Java based framework S2Directory to prove the effectiveness of the concept of Object-Directory Mapping. Implementation details are also given together with new dynamic implementation injection techniques.
