The immovable object is human nature, which includes social behaviors that evolved over the millions of years our ancestors lived in groups. Advances in semi-conductor technology — the irresistible force — have followed an unparalleled exponential curve that makes forecasting difficult or impossible. I will describe several perspectives on this dilemma that have come to seem particularly useful or important to me in the two decades since I began working in this area as a system and application developer.","PeriodicalId":340691,"journal":{"name":"2007 International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom 2007)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127256512","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}

Such systems are likely to support and make visible social attributes such as identity, reputation, trust, accountability, presence, social roles, expertise, knowledge, and ownership. Social computing is transforming organizations and societies by creating a pervasive technical infrastructure that includes people, organizations, their relationships and activities as fundamental system components, enabling identity, behavior, social relationships, and experience to be used as resources. In this talk, I argue for a broad definition of social computing, selectively review emerging applications, and discuss current research within and beyond IBM that is driving and is driven by the emerging vision of social computing.","PeriodicalId":340691,"journal":{"name":"2007 International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom 2007)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121475893","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}

Searching in these networks has been a hot research topic. Flooding-based searching, which has been the basis of real-world P2P networks is inherently inefficient and unscalable. Replication has proven to be an effective strategy to improve efficiency and scalability of unstructured P2P networks. Previous research has largely focused on replicating resources or their references. This paper considers a replication solution from a different perspective; we investigate replicating messages and its effect on overloading problem. We propose two message replication strategies. The distance-based message replication technique replicates the query messages at different topological regions of the network. The landmarks-based technique further optimizes the performance by considering both the topology as well as the physical proximities of the peers of the overlay. Our experiments show that the proposed techniques substantially reduce the message traffic in the overlay while maintaining query performance.","PeriodicalId":340691,"journal":{"name":"2007 International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom 2007)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117060880","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}

Therefore smart environment infrastructures need to be able to identify users needs (intention recognition) and to plan an appropriate assisting strategy. Both is matter for research. In our approach we address inferring the intention of a team within a smart meeting environment. This becomes a central challenge, especially if multiple users are observed by noisy heterogeneous sensors. We propose a team behavior model based on hierarchical dynamic Bayesian network (DBN) for inferring the current task and activity of a team of users online. Given (noisy and intermittent) sensor readings of the team members' positions in a meeting room, we are interested in inferring the team's current objective. We implemented the model using particle filters for inference and demonstrate that by adding knowledge about the meeting agenda prediction accuracy and speed is improved. Evaluation of simulation data answers the question, how precise agenda knowledge must be to predict team behavior optimally.","PeriodicalId":340691,"journal":{"name":"2007 International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom 2007)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117107390","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}

Regarding the design of systems of this kind, the most accurate middleware is the use of messages oriented middleware (MOM). One of the current issues which affects also to collaborative environments is interoperability. More concretely, the use of web service standards has gained its prominence in this area. The use of WS-Eventing and WS-Notification seem to be the most accurate specification for the building of interoperable MOM systems. The aim of this paper is to offer the design and implementation of an interoperable synchronous architecture for the delivery of messages between applications developed in different programming languages devoted to text-based tools, such as instant messaging and chat.","PeriodicalId":340691,"journal":{"name":"2007 International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom 2007)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128464819","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 motivate and explain here the idea of using distributed collaborative environments to perform this activity. In these environments, the initiative in distributing access rights to shared objects can be taken by information guardians, information consumers, and tools that act as agents of the guardians and consumers. Information consumers are responsible for sending access requests to information guardians; their agents (partially or completely) automate this task for them. Information guardians are responsible for authorizing accesses; their agents automate this task for them. The agents interact with collaborative and communication tools, which must be extended to support the new access-control paradigm.","PeriodicalId":340691,"journal":{"name":"2007 International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom 2007)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126836677","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}

Such devices could improve the competency of these workers when making on-the-spot decisions however there are many published cases of failure to adopt such innovations. In many instances the potential which the tool possesses to improve work has been recognised by workers and yet they persist with incumbent work methods. This paper examines one such case, namely print journalists reporting from the field. Major impediments to mobile technology adoption include the potential negative effect which the device has upon the established information system and, in particular, its influence on the level of collaboration of different mobile workers.","PeriodicalId":340691,"journal":{"name":"2007 International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom 2007)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121187602","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 several cases of real-world collaborations involving instant messaging, distributed lectures, and computationally-intensive collaborative game playing, we show that compared to traditional centralized and replicated collaboration architectures, a new bi-architecture collaboration system model with multicasting support can improve response, feedthrough, and task completion times. In addition, we show that to optimize performance, the set of traditionally considered factors, consisting of network delays and transmission costs, must be expanded to include several new factors, such as processing costs, scheduling policies, and think times. In one or more of the real-world collaborations we consider, we show that multicast (a) can increase feedthrough times if processing costs and scheduling policies are not considered and (b) may degrade or improve task completion times depending on the cost of computing the multicast overlay.","PeriodicalId":340691,"journal":{"name":"2007 International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom 2007)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114715182","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}
