We focus on the problem of shared ontology for the purpose of discovery in the CFDBS context. We introduce the concept and mechanism of the Dynamic Classificational Ontology (DCO), which is a mediator to help participants identify and resolve ontological similarities and differences. A DCO contains top level knowledge about information units exported by information providers, along with classificational knowledge. By contrast with fixed hierarchical classifications, the DCO builds domain specific, dynamically changing classification schemes; it specifically contains knowledge about overlap among information units. Information providers contribute to the DCO when information units are exported, and the current knowledge in the DCO is in turn utilized to guide export and discovery of information. At the cost of information providers' cooperative efforts, this approach supports much more systematic discovery than that provided by keyword based search, with substantially greater precision and recall. An experimental prototype of the DCO has been developed, and applied and tested to improve the precision and recall of Medline document searches for biomedical information sharing.","PeriodicalId":314823,"journal":{"name":"Proceedings First IFCIS International Conference on Cooperative Information Systems","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122357030","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}

With such systems, users frequently need not only be able to access information, but they also have to be notified automatically when new information that is relevant to their work becomes available. For example, an our environmental systems project, a civil servant needs to be informed when a measured air quality parameter exceeds a certain threshhold. Detection of such a critical situation requires subsequent monitoring of several data sources (e.g., a database recording measurement values and a database with limit values). The paper presents an approach for such situation monitoring which is based on CORBA, for the technical integration of heterogeneous systems and on active DBMS-style ECA-rules. In particular, it discusses how ECA-rules can be adopted in a CORBA environment, and describes a CORBA-based system for situation monitoring. The major implementation issues addressed are event detection within autonomous component systems and detection of complex distributed situations.","PeriodicalId":314823,"journal":{"name":"Proceedings First IFCIS International Conference on Cooperative Information Systems","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123161639","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}
