The domain-expert is a functional component of CIRCSIM-Tutor and provides the domain intelligence to the rest of the system. The authors have developed a multi-dimensional knowledge representation technique to capture expertise in the domain, which led them to the construction of a conceptual model of the domain-expert of CIRCSIM-Tutor. The authors describe how this conceptual model is transformed via an object-oriented methodology to yield the architecture of the domain-expert of CIRCSIM-Tutor. The conceptual model is at the epistemological level and has a real-world-orientation, whereas the architecture of domain-expert emphasizes system-orientation. The resulting architecture is query-driven and provides a fully transparent access to each chunk of domain knowledge, of different types, with optimal flexibility.<<ETX>>","PeriodicalId":250310,"journal":{"name":"[1993] Computer-Based Medical Systems-Proceedings of the Sixth Annual IEEE Symposium","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122509134","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}

The configuration of the HLND system includes the following processing phases: data acquisition and pre-processing, in order to reduce and to enhance the figure-background contrast; quick selection of nodule suspects based upon the most prominent feature of nodules, the disc shape; and complete feature space determination and neural classification of nodules. Nodule suspects are captured and stored in 32*32 images after first two processing phases. Eight categories including true nodule, rib-crossing, rib-vessel crossing, end vessel, vessel cluster, bone, rib edge, and vessel are identified for further neural analysis and classification. Extraction of shape features is performed through the edge enhancement self-organized Kohenen feature map, histogram equalization, and evaluation of marginal distribution curves. A supervised back-propagation-trained neural network is developed for recognition of the derived feature curve, a normalized marginal distibution curve.<<ETX>>","PeriodicalId":250310,"journal":{"name":"[1993] Computer-Based Medical Systems-Proceedings of the Sixth Annual IEEE Symposium","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130735289","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}

This integration is crucial to providing physicians with comprehensive views of their patients' clinical state. It also can provide a broader clinical context for intelligent monitoring programs and thereby increase the sensitivity and specificity of their alarms. We describe an implemented application programming interface (API) that provides an abstracted query interface to the hospital's central, relational database and to data extracted from the monitors. The API also provides several data-reduction operators to help manage the large volume of data generated. We describe an electronic flowsheet that was built using the API.<<ETX>>","PeriodicalId":250310,"journal":{"name":"[1993] Computer-Based Medical Systems-Proceedings of the Sixth Annual IEEE Symposium","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117053838","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}
