Business-intelligence using data mining has felt an increased thrust for real-time frequent pattern mining algorithms finding huge demand from numerous real-time business applications like e-commerce, recommender-systems, group-decision-support-systems, supply-chain-management, to name a few. Last decade has seen development of mind-whelming algorithms, among which, vertical-mining algorithms have been found to be very effective. However, with dense-datasets, the performances of these algorithms significantly degrade. Moreover, these algorithms are not suited to respond to the real-time need. In this paper, we describe BDFS(b)-diff-sets, an algorithm to perform real-time frequent pattern mining using diff-sets and using an intelligent staged search technique, by-passing usual breadth-first and depth-first search-techniques. Empirical evaluations show that our algorithm can make a fair estimation of the probable frequent-patterns reacting to the user-defined time bound and reaches some of the longest frequent patterns much faster than the existing algorithms.","PeriodicalId":223683,"journal":{"name":"International Workshop on Ubiquitous Data Management","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123888713","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}

Our target photographs are enhanced with spatial metadata such as geographic coordinates where they were taken and directions where they focused on. We assume photographs having such spatial metadata become popular. In a common framework, such photographs are mapped to their viewpoints by using their location information generated by GPS. We think this framework has less function for practical spatial queries. For example, even if a photograph is mapped to a certain point on a map, a scene of the point may not be shown in the photograph. It may show a different direction than user wants to see. A problem is that though locations or objects shown in photographs are important for users, viewpoints are not positions of them but positions of cameras from which photographs were taken. We therefore map each photograph to a vector from its viewpoint to its gazing point, and named the vector as photo vector. A prototype system based on our framework provides functions such as handling advanced spatial queries for retrieving photographs, visualizing how many photographs show each location, and mapping text labels having URLs and geographic coordinates to the appropriate positions on photographs. In this framework, photographs, maps and cyberspaces are mapped to each other.","PeriodicalId":223683,"journal":{"name":"International Workshop on Ubiquitous Data Management","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122200494","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}

Individuals working in these environments are increasingly permanently connected to rich information resources. An appealing opportunity of these environments is the potential to deliver useful information to individuals either from their previous information experiences or external sources. This information should enrich their life experiences or make them more effective in their endeavours. Information access in ubiquitous computing environments can be made \"context-aware\" by exploiting the wide range context data available describing the environment, the searcher and the information itself. Realizing such a vision of reliable, timely and appropriate identification and delivery of information in this way poses numerous challenges. A central theme in achieving context-aware information access is the combination of information retrieval with multiple dimensions of available context data. Potential context data sources, include the user's current task, inputs from environmental and biometric sensors, associated with the user's current context, previous contexts, and document context, which can be exploited using a variety of technologies to create new and exciting possibilities for information access.","PeriodicalId":223683,"journal":{"name":"International Workshop on Ubiquitous Data Management","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133578752","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}
