  • This paper presents a prototype of document schema to guarantee the consistency of the bridge design information during the life-cycle of bridge. The main component of document schema for bridge design information is derived from the Document Type Definition (DTD) Pool which is the Construction CALS/EC standard in Korea and the document schema is implemented by using the XML Schema. The ifcXML are adopted for representing product data of bridge. A pilot system adopting the document schema and its application to existing bridge show that the suggested document schema can be efficiently used to develop software modules supporting the integrated design documents for bridges.

  • This study analyzed the current condition of authority control, introduced the MADS(Metadata Authority Description Schema) for authority data. MADS supports encoding an authority description for a agent(person, organization), event, term(topic, temporal entity, genre, geographic entity, hierarchical geographic entity, occupation) and defines main elements, subelements, and attributes using the XML schema language. Lastly, using the MADS's characteristics, this study proposed the effective use plans of interoperability of authority data.

  • In this paper, we introduce a new genetic reordering operator based on the concept of schema to solve optimization problems such as the Traveling Salesman Problem(TSP) and maximizing or minimizing functions. In particular, because TSP is a well-known combinational optimization problem andbelongs to a NP-complete problem, there is huge solution space to be searched. For robustness to local minima, the operator separates selected strings into two parts to reduce the destructive probability of good building blocks. And it applies inversion to the schema part to prevent the premature convergence. At the same time, it searches new spaces of solutions. Additionally, the non-schema part is applied to inversion for robustness to local minima. By doing so, we can preserve diversity of the distributions in population and make GA be adaptive to the dynamic environment.

  • XML documents, which are becoming new standard for expressing and exchanging data in the Internet, don't have defined schema. It is not adequate to directly apply XML documents to the existing SQL or OQL. Research on how to extract Schema for XML documents and query language is going on actively. For users' query, the results could be too tony or too less. It Is important to give the users adequate results. This paper suggests the way to extract many levelized schema according to the frequency of element occurrence in XML documents. The Schema can be reduced or extended to correspond to the users' query more flexibly.

  • GML (Geography Markup Language) has become the widely adopted standard for transport and storage of geographic information. So, various researches such as modeling, storage, query, and etc have been studied to provide the interoperability of geographic information in web environments. Especially, there are increased needs to store semi-structured data such as GML documents efficiently. Therefore, in this paper, we design and implement a GML repository to store GML documents on the basis of GML schema using spatial database system. GML Schema is converted into directed GML schema graph and the schema mapping technique from directed schema graph to spatial schema is presented. Also, we define the conversion rules on spatial schema to preserve the constraints of GML schema. GML repository using spatial database system is useful to provide the interoperability of geographic information and to store and manage enormous GML documents.

  • B2B e-business is an economic transaction formed between companies through various networks including internet. At present, e-business between companies partly applies information distribution between companies, but many enterprises expect that a corporate basic system will be gradually changed into XML basis if web service is earnestly materialized, so they are competing with each other in developing XML DBMS. Existing XML DBMS studies used XML DTD in order to represent the structure of XML document. Such XML DTD defines the expression of a simple type, so there are many difficulties in defining the structure of XML document. To cope with this, in this paper, the author will develop database schema generator utilizing relational database generally used in storing contents of data, on the basis of XML schema selected as a standard of W3C. Also, to store XML data, the author proposed the automatic conversion method of relational database schema that used XML schema.

  • As humans perform many tasks using computers, HCI(Human-Computer Interaction) has received much attention these days. One objective of HCI research is to propose how to design more consistent systems. In order to evaluate the consistency of HCI devices from the user's perspective, several models such as TAG(Task Action Grammar), GOMS(Goals-Operators-Methods-Selection Rule), and GTN(General Transition Network) have been developed. TAG specifies actions to perform tasks in terms of rule schema. It has been verified that the less the number of rule schema is, the better users perform the tasks due to assumably higher consistency. This paper hypothesizes that the consistency of systems depends not only on the number of rule schema but also on the distances between rule schema. That is, the closer the rule schema are, the easier it is to acquire the whole set of rule schema. An experiment supported this hypothesis. Therefore, distances between rule schema should be considered as well as the number of rule schema when designing systems.

  • Web-based map services provide various geographic information that users want to get by continuous updating of data. Those map services provide different information for a geographic object respectively. It causes several problems, and most of all various information cannot be integrated and provided. To resolve the problem, this paper proposes a system which can integrate diverse geographic information and provide users rich geographic information. In this paper, a hybrid schema matching (HSM) algorithm is proposed and the algorithm is a mixture of the adapter-based semantic processing method, static semantic management-based approach, and dynamic semantic management-based approach. A comparative evaluation is described to show effectiveness of the proposed algorithm. The proposed algorithm in this paper improves the accuracy of schema matching because of registration and management of schemas of new semantic information. The proposal enables vocabulary-based schema matching using various schemas, and it thus also supports high usability. Finally, the proposed algorithm is cost-effective by providing the progressive extension of relationships between schema meanings.

  • Nowadays, the robot with various and complex functions is required. previous algorithms, however, cannot satisfy the requirement. In order to solve these problems, we introduce the 2-Layer Fuzzy Controller, which has a small number of fuzzy rules corresponding to various inputs and outputs. Also, it controls robustly and effectively an object. The main problem in the fuzzy controller is how to design the fuzzy rule. This paper designs the optimal 2-layer fuzzy controller using the Schema Co-Evolutionary Algorithm. The schema co-evolutionary algorithm can find more rapidly and excellently than simple genetic algorithm does.

  • Currently lots of studies to solve meta-data interoperability in between schema attributes are conducted. But the accuracy in previous schema mapping studies is low since the studies just use the similarity in between attributes. So the studies are not suitable for the schema mapping such as document conversion, system integration, etc. In this paper, we propose a method which can conduct the schema mapping interactively using frequent pattern mining. The method can conduct more accurate mapping process because the method use the description element which is an element among each schema element for the metadata standard. A performance study has been conducted to compare the accuracy performance of the method using metadata standards.
