However, while properties extracted from images are usually fuzzy data, most of the time a navigation structure will deal with binary links from an image (or a group of images) to another. A trivial solution to get a binary relationship from fuzzy data is to apply a threshold, but this solution not only leads to a loss of information but fails to distinguish noise from interesting elements. In this paper, we propose two techniques to eliminate isolated elements and lead to a structure made of more compact subparts. The first one is based on a variable threshold depending on the number of neighbours. The second one, specific to Galois’ lattice, is based on taking into account the existing navigation structure for binarisation of descriptions. Experiments showed that it improves the resulting structure by reducing the number of nodes without loosing information on image description, thus improving user experience.","PeriodicalId":396555,"journal":{"name":"21st International Conference on Data Engineering Workshops (ICDEW'05)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123043717","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}

For controlling these problems when human face image sets are considered, a new approach, called the MIFLIR system, is presented in this paper. This approach allows reducing the semantic gap by using fuzzy predicates during the indexing and the retrieval of images. In addition to this, our system innovates by using a metric indexing method to accelerate perceptibly the retrieval of images. Experimental results show that the MIFLIR system reduces noticeably the total time for performing fuzzy queries, when compared to a similar system which uses sequential scan search method.","PeriodicalId":396555,"journal":{"name":"21st International Conference on Data Engineering Workshops (ICDEW'05)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123711429","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}

As a first step to address this issue by summarizing retrieved papers, we developed a system to classify sentences of abstracts obtained from the MEDLINE database into five rhetorical statuses: background, purpose, method, result, or conclusion. We used Support Vector Machine (SVM) classifiers and trained each of them for a different rhetorical status on structured abstracts. A structured abstract is one that has labels indicating rhetorical statuses of the sentences, while an unstructured abstract does not. The classifiers were tested on both structured and unstructured abstracts. The former were randomly obtained from the MEDLINE database and the latter were manually labeled by humans. We compared our method with a previously reported one. In addition, we combined them and evaluated the combined method. Our method outperformed the previously reported one, and the combined method showed even better results. Classified abstracts can be used for multi-document summarization that provides researchers with a way of learning a research topic efficiently and effectively.","PeriodicalId":396555,"journal":{"name":"21st International Conference on Data Engineering Workshops (ICDEW'05)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129952251","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 third technique is dynamic scoring which tempers the link structure analysis of the retrieval result set with Web Page Grouping.

Our research group has proposed a multiple query optimization method for continuous queries. In our method, the system forms clusters of queries with similar execution patterns, and derives query plans sharing the result of common operators. Our previous experiments have shown that a parameter value in the clustering phase controls divisions of clusters and has a great impact on query processing effi- ciency. However, the optimal parameter value must be decided by trial and error. This paper extends our previous work. The proposed method automatically estimates the optimal value and iteratively adjusts it even if properties of underlying data streams dramatically change.","PeriodicalId":396555,"journal":{"name":"21st International Conference on Data Engineering Workshops (ICDEW'05)","volume":"294 1-2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114105692","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}

Online property of data integration means continuous integration of transmitted data with the already available results. Adaptivity materializes in a form of dynamic adjustments to the data integration plans in a response to the recent characteristics of data transmission. Implementation of adaptive and online data integration needs the specialized systems of operations and transformations of integration plans. This paper describes a new class of elementary operations on increments and/or decrements of data and shows how to express data integration plans as sequences of elementary operations. We demonstrate that class of operations proposed in the paper is sufficient for implementation of online and adaptive data integration systems and we discuss the operational properties of such systems.","PeriodicalId":396555,"journal":{"name":"21st International Conference on Data Engineering Workshops (ICDEW'05)","volume":"530 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124508372","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 SBE enforcedly eliminates the subband components in which the separation could not be performed well.
