The main features that distinguish this tool from others with the same purpose are the inclusion of filtering mechanisms based on semantic criteria and the use of multiple representations with different levels of detail. Filtering mechanisms contribute to reduce the amount of displayed data allowing the generation of intelligible representations. The user selects interactively the categories she/he is interested in. This is a basic filtering mechanism, but besides this, a degree of interest function is used to include semantic criteria. This function quantifies the user's interest in order to visualize the most relevant data, suppressing the less relevant data.The definition of multiple representations with different levels of detail enables the reduction of the detail when small scales are being used. In addition less detailed representations are used to present less relevant data.","PeriodicalId":167948,"journal":{"name":"Workshop on Geographic Information Retrieval","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128556507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Discovering suitable geoprocessing services is a major challenge in this endeavour. Current (keyword-based) approaches to service discovery are inherently restricted by the ambiguities of natural language, which can lead to low precision and/or recall. To alleviate these problems, we propose a methodology for service discovery which uses ontologies describing geospatial operations to create descriptions of requirements and service capabilities. Matches between these descriptions are identified based on function subtyping. This paper investigates how this methodology an be integrated into existing architectures for spatial data infrastructures, and presents a prototypical implementation.","PeriodicalId":167948,"journal":{"name":"Workshop on Geographic Information Retrieval","volume":"171 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115700606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
