A Fundamental Framework for Realizing Semantic Interoperability in a Multidatabase Environment

In this paper, we present an implementation study for constructing a meta-level career design support system for connecting educational and occupational databases. This system is implemented as a multi-database system for dealing with educational and occupational information. This system has functionalities for measuring correlations among databases of Educational Issues, Occupations and Lectures. With these functionalities, our system totally supports users to design for specifying concrete occupations corresponding to their goals and objectives, to construct curriculums with an actual set of lectures. This system supports users enables users to specify significant educational contents, and to design the path for career development and learning, dynamically according to users' interests and social situations.

In this paper, we present an implementation of a se mantic associative search space for medical document databases.We have implemented a semantic associative search space for the medical field by using encyclopedias which describe not only word definitions but also word explana tions.This implementation realizes a medical semantic asso ciative search space by using a medical encyclopedia which includes explicit word explanations.We have created an actual medical semantic associative search space which consists of 149 dimensions computed from the 217x219 matrix consisting of medical data.By using this actual medical space, we show several ex perimental results of semantic associative search space cre ation and medical document retrieval for clarifyingfeasibil ity of our implementation method.

“…Mapping matrixes are used to map input into the semantic space. Different mapping matrixes are required when the semantic space model is applied in different application areas [7][8][9][10][11][12][13][14][15]. Therefore, we developed many methods to create mapping matrixes and apply the model in the areas of semantic information retrieving [10,11,15], semantic information classifying [12], semantic information extracting [13], and semantic information analyzing on reason and results [15], etc.…”

The most important mechanism of the computer is that various functions are implemented based on programs stored in it. Programs are developed by program languages implementing functions of models. One of the efficient methods to construct a model is to construct it by semantic computation models. Using semantic computation models, we can construct a model in a semantic space. In this paper, we present a mechanism to execute models presented by the semantic spaces. We have presented a mechanism to implement combinational and sequential logic computations based on the semantic space model. The combinational and sequential logic computations are the basic functions in computer systems. However, we still need a control mechanism like that in computers. In this paper, we present a control mechanism based on the semantic space model and some of execution examples. The most important contribution of this paper is that we first present a concept for control and program based on the semantic space model. In order to demonstrate the efficiency of the proposed mechanism, we performed a demonstration experiment. In the experiment, an agent is constructed for unmanned ground vehicle control with the control mechanism. A video camera is used to determine the position of the vehicle and obstacles on the road. The control signals, including “turn left,” “turn right,” “go ahead” and “stop” outputted from the agent are used to demonstrate the efficiency of the mechanism.
