According to the traditional way, the tenant has to rent and customize with the same SaaS application many times, which results in a lot of repeated custom operations and duplication of custom metadata. In this paper we design a novel metadata-driven schema-sharing data storage architecture for multi-level Customization in SaaS applications, which supports sharing custom metadata in a tenant domain, reduces duplication of customization, and facilitates unified management of a tenant’s institutions, users, roles, code, business applications, business data, etc.","PeriodicalId":122827,"journal":{"name":"2010 Seventh Web Information Systems and Applications Conference","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123688461","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}

Various trust management polices are proposed to improve these issues. However, most of these existing approaches only take into account a global attribute. The evaluation granularity is too coarse for customers to make an exact transaction decision. This paper proposes a service-oriented trust management framework for E-commerce systems. It consists of an authentication center, an evaluation controller, a reference controller, an update controller and a history controller. Considering the different services have different quality of service and content, our model evaluates a node under each separate service category, the evaluation result is more exact than some existing approaches and can reduce the risk of transactions. Finally, an example is given to analyze the feasibility and security of the model.","PeriodicalId":122827,"journal":{"name":"2010 Seventh Web Information Systems and Applications Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122927256","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}

However, exact location information transmitted to an unsecure server will easily lead the mobile user to be tracked. Thus it is important to protect mobile users’ location privacy while providing location-based services. People traveling over roads always follow a road network. We observe that two cloaking subgraph structures, which we name cloaking cycle and cloaking tree, can be used to protect mobile users’ location privacy effectively in road network environment. Based on these two subgraph structures, we propose a novel location privacy preserving approach using cloaking cycle and forest, which can effectively protect mobile users’ location privacy while efficiently providing exact location-based services.","PeriodicalId":122827,"journal":{"name":"2010 Seventh Web Information Systems and Applications Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115187042","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}

We focus on the sentence-level sentiment classification. On the systematically analyzing the importance and difficulties of the sentence-level sentiment classification, this paper proposes a syntax tree pruning and tree kernel-based approach to sentiment classification. In our method, the convolution kernel of SVM is first used to obtain structured information, and then apply syntax tree as a feature in Sentiment Classification. Firstly, we focus on how to apply the structured features from the syntax tree to the sentiment classification and propose a novel approach of sentence-level sentiment classification which apply the tree kernel and composite kernel to the SVM classifier. Secondly, we provide two kinds of syntax tree pruning strategies: adjectives-based and sentiment words-based. The experimental results show that our method can achieve better performance in sentence level Sentiment Classification.","PeriodicalId":122827,"journal":{"name":"2010 Seventh Web Information Systems and Applications Conference","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125733896","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 topic-oriented communities discovery, we analyze some insufficiencies of CBG (complete bipartite graph) in trawling method. The conception of x-core-set is introduced, instead of CBG, it is more reasonable as a signature of core of community. We construct a bipartite graph from a node x and then (i, j)pruning the graph to obtain x-cores-set. By scanning topic subgraph, we can extract a set of x-cores-sets. Finally, a hierarchal clustering algorithm is applied to these x-cores-sets and the dendrogram of community is formed. We proved that x-cores-set, consisted of x-cores, can be calculated by a bipartite graph collected from x and (i, j)pruning. The experiment is set up on the dataset that is same as that in HITS method, except for returned pages are integrated from 4 search engines. The result shows that our algorithm is effective and efficient.","PeriodicalId":122827,"journal":{"name":"2010 Seventh Web Information Systems and Applications Conference","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125953395","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}

In this paper, with click-through data analysis, a inverted file replacement algorithm for WEB caching is proposed. The analytic result shows that the click-through data for the cache updating algorithms is how the algorithm suits the WEB traffic pattern properly. Based on the poisson arrival model, a new cache policy, inverted file replacement algorithm, is proposed. The trace driven simulation shows that the retrieval algorithm under the new organization of the inverted file can decrease its execution time significantly and the performance of the inverted file replacement algorithms is better than that of the existing algorithms proposed in the literature.","PeriodicalId":122827,"journal":{"name":"2010 Seventh Web Information Systems and Applications Conference","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132735004","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}
