When a domain needs to allow entities from previously unknown domains to access its resources, mechanisms should be in place to allow negotiating trust and services based on the sharing requirements of the interacting domains. We emphasize that a holistic framework for requirements-driven trust based secure interoperation is needed to facilitate interacting domains to access each other's local resources through access control policy mapping between the domains. In this paper, we present our ongoing work on developing a comprehensive framework for a trust based access control for secure interoperation, which tightly integrates role-based access control and inter-domain policy mapping mechanism with an integrated, game-theory based trust and service negotiation process. The framework being developed aims to address the complex requirements of an environment that represents the convergence of grid, peer-to-peer and mobile environments and workflow and multimedia technologies.","PeriodicalId":315775,"journal":{"name":"2006 International Conference on Collaborative Computing: Networking, Applications and Worksharing","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133627342","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}

It has been achieved by extending tuple space computing to support RDF as triple space computing. It can play an important role by acting as global middleware providing support for collaboration of different semantic technologies. Several participants from semantic Web and semantic Web services applications, distributed worldwide communicate with each other via triple space due to which the possibility of heterogeneity in the RDF schemas and instances among the communicating participants may arise. In order to resolve this heterogeneity issue, data mediation becomes an important part of the triple space computing architecture. In this paper we introduce data mediation support for triple space computing and further explain how mismatches occur in RDF data, presents an abstract mapping language to specify mapping to cover the heterogeneity, defines architecture of the mediation engine and its interfaces, processing of mediation mapping rules, grounding of mediation rules as RDF triples and finally evaluates with examples","PeriodicalId":315775,"journal":{"name":"2006 International Conference on Collaborative Computing: Networking, Applications and Worksharing","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114680980","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 such scenarios, different teams, belonging to different organizations, need to collaborate with one other to reach a common goal; each team member is equipped with handheld devices (PDAs) and communication technologies, and should carry on specific tasks. In such a case we can consider the whole team as carrying on a process, and the different teams (of the different organizations) collaborate through the \"interleaving\" of all the different processes (macro-process). Each team is supported by some back-end centre, and the different centres need to cooperate at an inter-organizational level to reach an effective coordination among teams. The project investigates a 2-level framework for such scenarios: a back-end peer-to-peer community, providing advanced services requiring high computational power, data & knowledge & content integration, and a set of front-end peer-to-peer communities, that provide services to human workers, mainly by adaptively enacting processes on mobile ad-hoc networks","PeriodicalId":315775,"journal":{"name":"2006 International Conference on Collaborative Computing: Networking, Applications and Worksharing","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126131658","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}

Each participant must be able to reach the new meeting location, attend for the entire duration, and reach the next meeting location on time. In particular, we give a solution to the problem instance where each participant has two scheduled meetings separated by a free time interval. For a geometric model, where n participants can travel along straight paths in the Euclidean plane, we present an O(n log n) algorithm to determine the longest meeting duration and a location suitable to all participants. In a graph-based model, transportation is provided by a geometric network over m nodes and e edges in the plane. Participants can have individual weights. Moreover, there can be k groups of participants, such that only one member of each group must attend the meeting. In this model, a location for a meeting of longest possible duration can be determined in time O(enalpha(k) log k + n log n + mn log m), where alpha(k) denotes the extremely slowly growing inverse Ackermann function","PeriodicalId":315775,"journal":{"name":"2006 International Conference on Collaborative Computing: Networking, Applications and Worksharing","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114892268","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}

Participants in co-located collaboration benefit from the availability of non-verbal communication, including gestures, eye gaze and body movements. However, when geographically separated, they can experience difficulty in communicating - as computer-mediated cues are often compromised. Given the heterogeneity of media and myriad of interaction techniques that exist in groupware, supporting inter-referential awareness can be difficult. We present a unified and systematic way of encapsulating the numerous factors related to this form of awareness through the creation of process-driven ontology. Our framework provides a formal method for describing inter-referential awareness, and serves as approach that interface designers can use to better comprehend the relevant factors involved. This research stems from our previous investigations in inter-referential awareness in collaborative augmented reality environments","PeriodicalId":315775,"journal":{"name":"2006 International Conference on Collaborative Computing: Networking, Applications and Worksharing","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114093645","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}
