Towards the Easy Manipulation of Graph-Based Content Representation of Multimedia Data
Teruhisa Hochin 대한전자공학회 2008 ITC-CSCC :International Technical Conference on Ci Vol.2008 No.7
The contents of multimedia data has complex relationships including deeply nested whole-part and the manyto-many relationships. A data model incorporating the concepts of directed graphs, recursive graphs, and hypergraphs has been proposed for representing the contents of multimedia data. In this data model, an instance is represented with a directed recursive hypergraph called an instance graph. This paper studies on the characteristics of instance graphs. The depth of an edge of an instance graph is introduced. When the depth of an edge is equal to zero, the instance graph can be decomposed into sub-instance graphs. Decomposing instance graphs could make their treatment easy.
Personalization Method of Multimedia Data Retrieval System Based on Impression
Teruhisa Hochin 대한전자공학회 2008 ITC-CSCC :International Technical Conference on Ci Vol.2008 No.7
This paper addresses to two major issues to the personalization of multimedia data retrieval system based on impression. One is on the decrease of the learning burden. The proposed method estimates the scores of an individual based on the grouping. The other is on the stability of the retrieval system. The proposed method uses a kind of rotation of a matrix. This method could keep the factors used in the system. This brings the stability to the retrieval system. By using these two methods, the user adaptation is easily, quickly, and stably attained.
Cultivation History Entry System for Agricultural Products
Hitoshi Nitta,Hiroki Takeda,Teruhisa Hochin 대한전자공학회 2008 ITC-CSCC :International Technical Conference on Ci Vol.2008 No.7
Pesticide legislation in Japan is very complex. It is a virtually impossible task that the farmer understands all of this law. To solve this problem, the authors have developed “Cultivation History Entry System for Agricultural Products”. Even the farmer who does not completely understand pesticide legislation comes to be able to do farm works that uphold pesticide legislation by using this system. This system equips improved usability by adoption of AJAX (Asynchronous JavaScript+XML) technology. Because this technology enables a server access without screen transition, this system is superior to the past system for agricultural products in response performance and visibility.
