Interdisciplinary Contents Management Using 5W1H Interface for Metadata

In this paper, we propose a metadata exchange interface for interdisciplinary contents-sharing. The interface is obtained by introducing the research results of a specific sociological study. We have developed a contents management (CM) system on intra-university network to test the feasibility of our interface. The main feature of our system is its function of focusing searches in Web documents. Our interface module converts tag-labels into items of 5W1H. By conducting an experimental use of our system, we confirmed that the module on it is very important for contents sharing across various disciplines

On a Sufficient Condition for the Existence of Most Specific Hypothesis in Progol

In this paper, we give a sufficient condition for the existence of the most specific hypothesis (MSH) in Progol. Muggleton [2] showed that for any first order theory (background knowledge) B and a single clause (a positive example) E, there exists the most specific hypothesis ¬bot(B, E) which satisfies B ≈ ¬,bot(B, E) ⊨ E and for any hypothesis H satisfying B ≈ H ⊨ E, H entails bot(B, E) assuming that hypotheses are all single clauses. Yamamoto[8] gave a counter example and indicated that Muggletons proof contains error. He also gave a sufficient condition under which the MSH exists. In this paper, we give another and more realistic sufficient condition to guarantee the existence of the MSH.

Systems engineering education for inexperienced students by providing hand-on practices

This paper presents results and lessons learned from a trial course on systems engineering for graduate students with little experience in industries. This course provides students with hand-on education for system engineering using commercially-off-the-shelf (COTS) components and a sizable amount of development works within the limitation in one semester (26 slots of lectures).

Project concept: Design concept of ad-hoc Information Network System for disaster mitigation

We have gone through national crises caused by earthquakes and tsunamis. Through these experiences we have established advanced communication systems and advanced disaster medical response systems. However, Japan was devastated by the Great East Japan Earthquake occurred on March 11th, 2011. Huge tsunamis swept a vast area of Tohoku causing a complete breakdown of all the infrastructures including telecommunications. Communication of emergency information was limited causing a serious delay in the initial rescue and medical operation. For the emergency rescue and medical operations, it is the most important to identify the number of casualties, their locations and states and to dispatch doctors and rescue workers from multiple organizations. In the case of the Tohoku earthquake, the dispatching mechanism and/or decision support system did not exist to allocate the appropriate number of doctors and locate disaster victims. Even though the doctors and rescue workers from multiple government organizations have their own dedicated communication system, the systems are not interoperable. In the area of the disaster management, introduction of cutting edge ICT is urgently needed. In this paper, we propose a design concept of Emergency Temporal Information Network System designed in a system of systems in the Acute Stage of Large-scale Disasters Damage Mitigation.

Contents Sharing Framework Using CCCI Model for Intra-University Network

In this paper, we propose a contents sharing framework using 3D Model named Context Cube for Contents Indexing (CCCI). The CCCI model is obtained by introducing the research results of a specific sociological study into the subject of our experimental study. It helps to extract semantics from various disciplines contents where some terms are used for different meanings and different terms are used for the same meanings. We developed an Enterprise Contents Management System for an academic domain, in order to validate our model. We conducted an experimental study of this system against the existing digital contents of our university, and succeeded in efficiently obtaining suitable contents along given contexts which were obtained through previous searches. By performing this experiment, we confirmed that context mining is one of the most important research issues to be further developed to promote knowledge circulation through digital contents.
