On Coordinating Collaborative Objects

A collaborative object represents a data type (such as a text document) designed to be shared by a group of dispersed users. The Operational Transformation (OT) is a coordination approach used for supporting optimistic replication for these objects. It allows the users to concurrently update the shared data and exchange their updates in any order since the convergence of all replicas, i.e. the fact that all users view the same data, is ensured in all cases. However, designing algorithms for achieving convergence with the OT approach is a critical and challenging issue. In this paper, we propose a formal compositional method for specifying complex collaborative objects. The most important feature of our method is that designing an OT algorithm for the composed collaborative object can be done by reusing the OT algorithms of component collaborative objects. By using our method, we can start from correct small collaborative objects which are relatively easy to handle and incrementally combine them to build more complex collaborative objects.Comment: In Proceedings FOCLASA 2010, arXiv:1007.499

EPISOSE: An Epistemology-based Social Search Framework for Exploratory Information Seeking

Abstract. Search engines are indispensable for locating information in WWW, but encounter great difficulties in handling exploratory information seeking, where precise keywords are hard to be formulated. A viable solution is to improve efficiency and quality of exploratory search by utilizing the wisdom of crowds (i.e., taking advantage of collective knowledge and efforts from a mass of searchers who share common or relevant search interests/goals). In this paper, we present an epistemology-based social search framework for supporting exploratory information seeking, which makes the best of both search engines' immense power of information collection and pre-processing and human users' knowledge of information filtering and post-processing. To validate the feasibility and effectiveness of the framework, we have designed and implemented a prototype system with the guidance of the framework. Our experimental results show that an epistemology-based social search system outperforms a conventional search engine for most exploratory information seeking tasks

The Thirteenth International Workshop on Collaborative Editing Systems

International audienceCollaborative editing (CE) has been an area of continuous research since early days of CSCW. Various CE systems have been studied in academia as research vehicles to investigate key technical issues in building advanced collaborative applications. In recent years, CE techniques have been increasingly adopted and further developed in industry for supporting real-world Internet or Cloud-based CE systems/services, such as Google Docs, Codoxware, IBM OpenCoWeb, Novell Vibe, and SubEthaEdit. This workshop aims to bring together CE academic researchers, industry developers, and end- users to discuss and exchange ideas on contemporary issues in researching, developing, and adopting CE systems. We have successfully organized this workshop annually at CSCW-related conferences. This year's workshop focuses on CE issues and techniques for supporting complex real-world documents (including but not limited to rich text, xml, spreadsheet, 2D/3D digital media, CAD, video, etc.), and evaluation of CE systems for such complex real-world documents

The Fourteenth International Workshop on Collaborative Editing Systems

International audienceInterest in collaborative editing (CE) has seen a dramatic rise in recent years. The ubiquity of cloud services, crowdsourcing, and mobile devices means that today's Internet citizens are increasingly accustomed to producing and editing data in a shared network environment. While systems such as Google Drive, Microsoft Web Apps, Apache Wave and Codoxware allow users to collaboratively edit shared information, they have just begun to scratch the surface of CE's full potential. In the coming years, users will expect to be able to collaboratively create, share, and edit documents and data in a dynamic, real-time, and intuitive manor. This workshop aims to connect researchers, developers, and users to help explore the future of CE in tomorrow's information landscape. This year's workshop focuses on how researchers and industry practitioners can work together to accelerate delivery of CE capabilities to meet the needs of the typical information-age user

The Fifteenth International Workshop on Collaborative Editing Systems

International audienceNot long ago, real time collaborative editing (CE) systems were seen as a novelty to the average user, and a niche area of computer science research. Today, nothing could be further from the truth. Users are increasingly more connected and are creating more and more content online, on mobile devices, and in cloud based applications. Users are increasingly expecting collaborative editing functionalities in all of their applications. The focus of this year's workshop is: 1) to explore recent advances in the technologies that enable collaborative editing systems, 2) to evaluate the adoption of these technologies by commercial industry and the open source communities, and 3) to foster an exchange of ideas between CE researchers and end-user CE systems builders. The goal is to increase the adoption of recent technological advancements in CE research by practitioners and to have practitioners identify real-world challenges for future research
