Lastly, the health research community lacks easy-to-use data gathering tools to conduct applied research using data from social media websites. In this position paper we discuss and sketch our current work on addressing fundamental questions about information flow in cancer-related social media networks by visualizing and understanding authority, trust, and cohesion. We discuss the development of methods to visualize these networks and information flow on them using real-time data from the social media website Twitter and how these networks influence health outcomes by examining responses to specific health messages.","PeriodicalId":408382,"journal":{"name":"2011 IEEE Fifth International Conference on Semantic Computing","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123113756","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}

Domain-specific languages are developed with consideration for domain experts, and therefore are meant to be domain-friendly. However, their effectiveness in domain-specific models, when developed for knowledge management applications, is often limited by their expressiveness and implementation. In this paper we discuss current domain modeling practices, specifically the use of OWL (Web Ontology Language) and SWRL (Semantic Web Rule Language) within the context of product development, and how they often do not consider their intended application. To address this, we (1) recommend a set of best practices to account for domain context while promoting application-specific domain modeling, (2) propose that a metamodel be used to incorporate these practices early on in domain modeling and review how similar information has been represented in the past, and (3) discuss what factors should be considered in the development of such a metamodel in the future.","PeriodicalId":408382,"journal":{"name":"2011 IEEE Fifth International Conference on Semantic Computing","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126506929","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}

Instead, MDD has made models an integral part of the development process. As a result, software designers and developers can focus on high-level problem solving instead of low-level implementation details. However, the current research focus is on model transformations and overlooks the importance of code generation, which includes the generation of infrastructural code (the static aspects of the system) and business code (the behavioral aspects of the system). In this paper, we first analyze the root cause about why existing MDD approaches are only good at generating the infrastructural code. Then, we propose a comprehensive approach that considers functional, dynamic, and object modeling. This approach is able to generate both infrastructural and business code. Finally, we present a case study to evaluate the proposed approach. Through this case study, we identify some insights on automated code generation in MDD. Our results demonstrate that it is not only likely, but also possible to fully automate the code generation process in MDD.","PeriodicalId":408382,"journal":{"name":"2011 IEEE Fifth International Conference on Semantic Computing","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125419368","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}

Coverage is a core abstract feature of raster data, and coverage services are becoming a very important kind of web applications, especially in the geospatial domain. The OGC WCS and WCPS standards have invested a lot of effort to specify the capabilities and processing of web coverage services. However, a formal coverage Ontology for its semantic is still missing, which has severely impeded the development of diverse web coverage applications, their scalability in terms of complexity, and their automatic orchestration and interoperability on the semantic Web. Based on the existing geospatial specifications and industry standards, we proposed a web coverage Ontology (WCO) for modeling the core features of coverages, and it extended current semantic technologies with several new complex data types required by raster services. New reasoning capabilities down to the pixel level of raster data also have been investigated and implemented.","PeriodicalId":408382,"journal":{"name":"2011 IEEE Fifth International Conference on Semantic Computing","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130160094","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}

Recently, large numbers of users have collaborated to produce more structured information in the so called \"info boxes''.

This paper describes WiGipedia, a novel tool which provides an alternative to the traditional approach, by supporting editing of structured wiki data through two intuitive and interactive interfaces, facilitating user input on both tabular and graph-based representations of structured data. The tool allows users to identify and correct inconsistencies that are otherwise hidden across multiple articles. Furthermore, a novel recommendation algorithm is applied to assist users in their contribution to the wiki. The paper discusses design, implementation details, and results of a usability study in which the system compares significantly well against the traditional approach to editing Wikipedia infoboxes.","PeriodicalId":408382,"journal":{"name":"2011 IEEE Fifth International Conference on Semantic Computing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131060687","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}

These groups provide a narrative structure that ties in images that are temporally far apart and cannot be browsed easily. The media in the collection is analyzed by a variety of algorithms to generate metadata of different types. The media and associated metadata are represented as a transactional database, and frequent item set mining is employed to detect frequently occurring groups of images that share several metadata in common. It is expected that a user's primary picture-taking interests (e.g., baby, garden, school sports, etc.), will appear as groups based on some combination of underlying metadata. A confidence and interest measure relevant to the consumer domain is used to determine the quality of the frequent item sets and create a list of the top \"themes\" within the collection. We also detect annually recurring groups in multi-year collections, as these capture common themes such as birthdays and holidays. Because the detected recurring groups are strictly data-driven (with no a priori assumptions about a user's collection), they are customized to the type of content in specific user's collections. Experiments with large user collections show the usefulness of our approach.","PeriodicalId":408382,"journal":{"name":"2011 IEEE Fifth International Conference on Semantic Computing","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114795237","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}

Based on ethnographic studies, we find that people, going about their routine work, exhibit patterns in terms of their routine online activities and work rhythms. Such patterns can be comprised of many diverse types of events occurring over arbitrary durations. For example, they might include timing, duration and frequency of particular uses of hardware and software resources, manipulations of content, communication acts and so on. We use ethnography to identify and target significant patterns and computer logging to collect data on computer events that can be analyzed to find reliable correlates of those patterns. In this paper we discuss our methods and their potential for the development of novel types of applications that can identify normal activities and also spot telltale or deviant patterns. Such applications could be useful to users directly by providing helpful resources and content automatically or to the enterprise in general by automatically detecting performance problems, deleterious behaviors, or malicious activities.","PeriodicalId":408382,"journal":{"name":"2011 IEEE Fifth International Conference on Semantic Computing","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123616790","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}
