This study investigates the ontology-based public participation GIS(PPGIS). The major reason that ontology-based GIS has attracted attention in semantic communication in recent year is due to the wide availability of geographical variable and the imminent need for turning such recommendation into useful geographical knowledge. Therefore, this study has been focused on designing and implementing the pilot tested system for public participation GIS. The applicability of the pilot tested was validated through a simulation experiment for history tourism in Guri city Gyeongi-do, Focused on the methodology, the life cycle model which involves regional statues and user recognition, can be viewed as an important preprocessing step(specification, conceptualization, formalization, integration and implementation) for recommended geographical knowledge discovery by axiom. Focusing on practicality, ontology in this study would be recommended for geographical knowledge through reasoning. In addition, ontology-based public participation GIS would show integration epistemological and ontological approach, and be utilized as an index which is connected with semantic communication. The results of the pilot system was applied to the study area, which was a part of scenario. The model was carried out using axiom of logical constraint in the meaning of human-activity.

웹에서 다양한 웹 지리 지역 정보를 검색할 수 있는 시스템에 대한 요구가 증가하고 있다. 그러나 현재의 웹 검색 시스템은 사용자가 키워드로 지역 웹 문서를 검색하고 해당 웹 문서를 지도와 비교하여 공간정보를 취득하며, 다른 관련 정보를 얻기 위해서는 검색과 비교를 반복해야 하는 어려움이 있다. 따라서 본 논문에서는 비구조화 된 텍스트 웹 자원으로부터 지리정보 온툴로지(geo-ontology)를 확장할 수 있는 통합된 검색시스템을 제안한다. 이를 위해 문서의 정보에서 위치 정보를 추출하고 공간정보 위치 맵핑 기법을 적용하여 텍스트의 공간정보를 추출한다.

The purpose of this study is to investigate high school students' geographic misconceptions and their mechanisms of formation. Three main theories explaining why students develop misconceptions exist: 1) framework theory, 2) p-prim(phenomenological primitive) theory, and 3) categorization theory. This study chose three target geographic concepts, or, 1st and 2nd mountain ranges, secondary central business district and satellite city, and the Nopsae wind and the F$\ddot{o}$hn phenomenon. Then, this research explored students' typical misconceptions regarding these concepts and attempted to examine which theory explains the misconception forming processes most well. As a result, the following misconceptions were found. First, students understood that the numbers 1 and 2 denote the order of the formation of mountain ranges. Second, despite differences in their main functions, students tended to subsume the secondary central business district and satellite city under one functional category. Third, students believed that the Nopsae wind and the F$\ddot{o}$hn phenomenon are identical in hierarchy. This study explained students' creation of these misconceptions by applying the categorization theory in which students located a concept in an inappropriate location of an ontology tree.

This paper describes an application of information presentation based geographic map for maritime information, including navigation information. The work is motivated by the need to prepare maritime information representation and distribution for future generation Web network technology. This works consist of map generation using GML and application to maritime information. GML 3.0 became an adopted specification of the Open Geospatial Consortium(OGC) in January 2003, and is rapidly emerging as the world standard for the encoding, transport and storage of all forms of geographic information. This paper looks at the application of GML to one of the more challenging areas of maritime information. Specific features of GML of interest to maritime information provider are discussed and then illustrated through a series of maritime information case studies. The first phase of the work consists of the construction of GML application schema for using as a base map of maritime information. Maritime information is acquired from multiple sources, including standards documents, database schemas, lexicons, collections of symbol definition. The sources of GML ontological knowledge and the contribution of each source to the overall ontology are described in this paper. In the second phase, the prepared GML is used to create a prototype of the mixed maritime information as a base map - for tagging documents within the maritime domain. An overview of this prototype is included. One application area for these information elements described here is the integrated retrieval of maritime information from diverse sources, ranging from Web sites to nautical chart databases and text documents.

The control points are important assets of countries which express the most accurate location information that is used in surveying land and other measurements. The location information has played an important role in our daily lives with the development of ubiquitous technology. While many researchers have recently applied new technology like RFID(Radio-Frequency Identification) to the effective management of control points, the research into data retrieval and the interoperability of control point data is still primitive step. Therefore, we construct a data modeling to effectively manage control points using ontology data structure and focus on semantic retrieval method. Our retrieval system can provide the inferred and associated information among data using Prot$\acute{e}$g$\acute{e}$-OWL tool. Our system has advantages in reducing the number of repeated queries by hierarchy searching and improving the searching time by association searching. Also, we propose an effective method to construct retrieval systems being able to edit items of categories and properties without editing the related codes.

In the field of maritime transport, various researches on next generation of standards are underway to realize e-navigation. While IHO leading the way, many studies on several S-100 based standards for exchange, sharing and utilizing maritime geographical information and related data are going on. IHO S-100 as a profile of ISO 19100 series of standards. Based on their application and service they provide, there can be different S-10x standards. In order to support the safe operation, various information should be integrated. When integrating a various information, it is crucial to make sure the same data model should be treated consistently and interpreted clearly across different profiles, such as S-101, S-102, etc. in this case. In this paper, I suggested a way to covert maritime metadata of S-100 to ontology so that we can perform consistent semantic analysis and processing of data in S-100 standards, which is the basis of other S-10x standards.

In the present paper, the raison d'$\^{e}$tre of geography and geography education in the humanities are explained. Geography was not considered as ontology notion and geography was also not aware of regarding ontology. However, human being is the geographic existence. People occupy the space they live in and reveal their own existence by virtue of the space. In geography, we understand human existence by concrete things consisting of the space. Geography can explain the necessity for the space of origin where human being had lost and open a gate to find their own existence through it. Geography education can find the justification as to why we should teach it in 'now here'. We can make a bright future in geography education in terms of critical reflection at the ontological dimension. Geography and geography education have clear reason to exist in right here. That begins from the question of what relationship between human and space is and completes the raison d'$\^{e}$tre based on the answer.

Semantic search recently been used in the search field. POI is one of the most essential information that make up the geographic information, and many of the geographic information system has POI search function as a basic. In this study, we propose POI semantic search using collective intelligence. For this, we designed and implemented service that constructs empirical information from tag and image, and provides an intuitive spatial navigation experience. For POI search, collective intelligence platform that many users can participate to collect variety information was designed and implemented.

웹 정보의 의미적 검색을 위한 시맨틱 웹의 연구가 활발히 진행되고 있다. 시맨틱 웹에서 핵심이 되는 것은 온톨로지이다. 2004년 2월 W3C는 온톨로지 구축을 위해 RDF(S)와 OWL을 온톨로지 구축 언어의 표준으로 제정하고 총 13개의 기술문서를 공표하여, 온톨로지 언어의 정의와 구축 사례 및 활용의 내용을 제공하고 있다. 이로 인해, 많은 온톨로지들이 여러 목적에 의해 구축되고 있으며, 그 활용도는 점차 증가하고 있다. 하지만 지리정보의 검색을 위한 온톨로지는 구축이 어려우며 이에 대한 연구도 미흡하다. 이에 본 논문에서는 지역과 지역의 위치 정보, 지역 내의 건물 및 도로에 대한 위치정보를 온톨로지로 구축할 수 있는 방법과 이를 지리정보 검색에 활용할 수 있는 방안을 연구하였다. 그 결과, 우리는 위치에 대한 온톨로지 구축을 위한 3가지 어휘를 설계하였고, 이를 이용하여 효율적이고 의미적인 지리정보 검색이 가능하다는 것을 확인할 수 있었다.

GIS systems have gradually been utilized in life information as well as special businesses such as traffic, sight-seeing, tracking, and disaster services. Most GIS services focus on showing stored information on maps, not providing a service to register and modify their preferred information. In this paper, we present a new method which reduces DXF map data into Simple Geographic Information File format using format conversion algorithms. We also present the prototype implementation of a GIS search system based on ontologies to support associated information. Our contribution is to propose a new digital map format to provide a fast map loading service and individual customized information on the map service.
