In this paper we address the problem of communicating heterogeneous negotiation agents in a Web-based environment, considering differences in their language implementations. Our research is based in the development of an ontology solution for describing and sharing negotiation primitives; and a translator module which is executed only when a not understood event occurs. We executed experiments in an electronic marketplace architecture, where heterogeneous agents participate in negotiation processes. The results of experiments show that the proposed solution improves the communication between negotiation agents","PeriodicalId":339667,"journal":{"name":"2006 Fourth Latin American Web Congress","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129278752","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}

This becomes a significant constraint when browsing over slow and intermittent networks. In this paper, we describe a readily deployable system designed for Web browsing over slow, intermittent networks - OWeB, that is minimally dependent on the real-time network availability and requires no changes on the part of the Web servers. The system subscribes to really simple syndication (RSS) feeds from Web servers and pre-fetches all new content as specified in the feed. Since the RSS feeds are published by Web servers they give accurate information about the new and updated content. Efficiency of network usage is achieved by employing standard techniques to handle intermittent networks, and near-complete utilization of all downloaded content results in better resilience in case of interrupted data downloads. We observed a co-relation between the items in an RSS feed and the homepage of the corresponding Web site (i.e.) the feed items essentially define the content section of the homepage. As part of OWeB, we developed an algorithm for automatically extracting the template of home pages and then locally stitching the feed items into the template. This results in Web sites being up-to-date and fully available offline and bandwidth savings, as we only need to download the RSS feed to construct the homepage","PeriodicalId":339667,"journal":{"name":"2006 Fourth Latin American Web Congress","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131231096","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}

One aspect that is usually neglected during a performance evaluation is the user reactivity, i.e., how the users react to variable server response time. This paper addresses the use of reactivity to improve the quality of service (QoS) of Internet services. We propose and evaluate two new scheduling approaches: the patient-first impatient-next (PFIN), and the impatient-first patient-next (IFPN). We design and implement the USAR-QoS simulator that allows the evaluation of QoS strategies considering the dynamic interaction between client and server sides. We simulate the new strategies using a TPC-W-based workload. The experiments show the benefits of the reactive policies which can result in better QoS for Internet services, improving the user satisfaction","PeriodicalId":339667,"journal":{"name":"2006 Fourth Latin American Web Congress","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127313219","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}

Finally, we compare two approaches to migration, automatic and manual, and discuss their strengths and weaknesses in our context.

Web-enabled Temporal OLAP 支持web的临时OLAP

In practice, dimension updates are often necessary in order to adapt the multidimensional database to changing requirements. Query languages are then needed to retrieve historical information from a data warehouse. Although many proposals addressing temporal OLAP exist, no one supports full operation over the World Wide Web. After introducing a temporal data model supporting historical dimensions and fact table versioning, we present a three-tier architecture based on Web services, SOAP and XML, allowing efficient querying over the Web. In this architecture, XML metadata is stored at the application server in the form of XML documents containing the data warehouse structure. This allows addressing most of the requests (navigation through time, updates, and queries) without accessing the data warehouse. We present our implementation, and also discuss query processing issues, like answering historical queries using materialized views","PeriodicalId":339667,"journal":{"name":"2006 Fourth Latin American Web Congress","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126064664","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}
