These systems process streaming data in real-time and provide instantaneous response to support precise and ontime decisions. In such systems, it is difficult to know exactly how a particular result is generated or more particularly how to precisely trace stream events that caused a particular result. However, such information is extremely important for validating stream processing results. Therefore, it is crucial that stream processing systems have a mechanism for capturing and querying provenance information - the information pertaining to the process that produced result data - at the level of individual stream events, which we refer to as fine-grained provenance. In this paper, we propose a novel fine-grained provenance solution called Stream Ancestor Function - a reverse mapping function used to express precise dependencies between input and output stream elements. We demonstrate how to utilize stream ancestor functions by means of a stream provenance query and replay execution algorithm. Finally, we evaluate the stream ancestor function in terms of storage consumption for provenance collection and system throughput, demonstrating significant reductions in storage size and reasonable processing overheads.","PeriodicalId":130476,"journal":{"name":"2012 Sixth International Conference on Research Challenges in Information Science (RCIS)","volume":"4299 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133309086","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 existing studies on data integration and reconciliation of results have been developed in an isolated way and did not consider the strong integration between these two processes. On one hand, ontologies were largely used for building automatic integration systems due to their ability to reduce schematic and semantic heterogeneities that may exist among sources. On the other hand, reconciliation of results is performed either by considering that all sources use the same identifier for an instance or by means of statistical methods that identify affinities between concepts. These reconciliation solutions are not usually suitable for real-world sensitive-applications where exact results are required and where each source may use a different identifier for the same concept. In this paper, we propose a methodology that simultaneously integrate source data and reconciliate their instances based on ontologies enriched with functional dependencies (FD) in a mediation architecture. The presence of FD gives more autonomy to sources when choosing their primary keys and facilitates the result reconciliation. This methodology is experimented using the Lehigh University Benchmark (LUBM) dataset to show its scalability and the quality of the reconciliation result phase.","PeriodicalId":130476,"journal":{"name":"2012 Sixth International Conference on Research Challenges in Information Science (RCIS)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128672215","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}

Model transformations that allow deriving (platform-independent) conceptual models from (computation-independent) requirements models are being proposed. However, rigorous assessments of the quality of the resulting conceptual models are needed. This paper reports a controlled experiment that compares the performance of subjects applying two different techniques for deriving object-oriented, UML-compliant conceptual models. We compare the quality of the OO-Method conceptual models obtained by applying a text-based derivation technique (which mimics what OO-Method practitioners actually do in real projects) with the quality obtained by applying a novel communication-based derivation technique (which takes as input Communication Analysis requirements models). The results show that there is an interaction between the derivation technique and the OO-Method modelling competence of the subject: the derivation technique has a significant impact on model completeness within the high-competence group. No impact has been observed on model validity. We also discuss new challenges raised by the evaluation.","PeriodicalId":130476,"journal":{"name":"2012 Sixth International Conference on Research Challenges in Information Science (RCIS)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127812200","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}

Yet, their integration in streamline engineering of interactive systems is bound to several shortcomings: they are hard to compare to each other, determining which one is the most suitable in which situation is a research problem, their performance largely vary depending on contextual parameters that are hard to predict, their fine-tuning in a real interactive application is a challenge. In order to address these shortcomings, we developed UsiGesture, an engineering method and a software support platform that accommodates multiple algorithms for pen-based gesture recognition in order to integrate them in a straightforward way into interactive computing systems. The method is aimed at providing designers and developers with support for the following steps: defining a dataset that is appropriate for an interactive system (e.g., made of commands, symbols, characters), determining the most suitable gesture recognition algorithm depending on contextual variables (e.g., user, platform, environment), fine-tuning the parameters of this algorithm by multi-criteria optimization (e.g., system speed and recognition rate vs. human distinguishability and perception), and incorporation of the fine-tuned algorithm in an integrated development environment for engineering interactive systems.","PeriodicalId":130476,"journal":{"name":"2012 Sixth International Conference on Research Challenges in Information Science (RCIS)","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131808368","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}
