In example-based NLP, the problem of eoml)utational cost of example retrieval is severe, since the retrieval time increases in proportion to the number of examples in the database. This paper proposes a novel example retrieval method for avoiding ftfll retrieval of examples. The proposed method has the following three features, 1) it generates retrieval(More)
In example-based NLP, the problem of computational cost of example retrieval is severe, since the retrieval time increases in proportion to the number of examples in the database. This paper proposes a novel example retrieval method for avoiding full retrieval of examples. The proposed method has the following three features, 1) it generates retrieval(More)
This paper presents a multi agent model for Reuse-Product markets. In the paper, by referring to previous studies, five prerequisites for reuse businesses are extracted. A simulation model with three types of agents: consumers and two types of companies, is proposed. The model contains eight parameters that reflect the prerequisites extracted. The model(More)
Ruthenium-catalyzed silylation of sp3 C-H bonds at a benzylic position with hydrosilanes gave benzylsilanes. For this silylation reaction, Ru3(CO)12 complex showed high catalytic activity. This silylation proceeded at the methyl C-H bond selectively. For this silylation reaction, pyridyl and pyrazolyl groups, and the imino group in hydrazones, can function(More)
Virtual classroom based on Internet is a promising tool for distance education. However, it is difficult for the instructor to instantly know the feedback and evaluation to learners in online courses. The paper gives one instructor-oriented virtual classroom system framework, by which the instructor may know each learner's reflection to his course in real(More)
