Guy, Ido, Jacovi, Michal, Shahar, Elad, Meshulam, Noga, Soroka, Vladimir and Farrell, Stephen (2008): Harvesting with SONAR: the value of aggregating social network information. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 1017-1026. Available online
“Web 2.0 gives people a substantial role in content and metadata creation. New interpersonal connections are formed and existing connections become evident through Web 2.0 services. This newly created social network (SN) spans across multiple services and aggregating it could bring great value. In this work we present SONAR, an API for gathering and sharing SN information. We give a detailed description of SONAR, demonstrate its potential value through user scenarios, and show results from experiments we conducted with a SONAR-based social networking application. These suggest that aggregating SN information across diverse data sources enriches the SN picture and makes it more complete and useful for the end user.”

“Human memory is fallible. We remember certain things, while we completely forget others. Some of the events we experience end up stored in our episodic memory, others disappear completely. Even those stored, very often remain inaccessible, since we do not have reliable mechanisms to retrieve them when required. In this paper we describe Pensieve, a system for augmenting episodic memory, that facilitates capturing of events and retrieving them later, using various relevant cues and associative browsing.”

“The CSCW conference is celebrating its 20th birthday. This is a perfect time to analyze the coherence of the field, to examine whether it has a solid core or sub-communities, and to identify various patterns of its development. In this paper we analyze the structure of the CSCW conference using structural analysis of the citation graph of CSCW and related publications. We identify the conference's core and most prominent clusters. We also define a measure to identify chasm-papers, namely papers cited significantly more outside the conference than within, and analyze such papers.”

Soroka, Vladimir and Rafaeli, Sheizaf (2006): Invisible participants: how cultural capital relates to lurking behavior. In: Proceedings of the 2006 International Conference on the World Wide Web 2006. pp. 163-172. Available online
“The asymmetry of activity in virtual communities is of great interest. While participation in the activities of virtual communities is crucial for a community's survival and development, many people prefer lurking, that is passive attention over active participation. Lurking can be measured and perhaps affected by both dispositional and situational variables. This work investigates the concept of cultural capital as situational antecedent of lurking and de-lurking (the decision to start posting after a certain amount of lurking time). Cultural capital is defined as the knowledge that enables an individual to interpret various cultural codes. The main hypothesis states that a user's cultural capital affects her level of activity in a community and her decision to de-lurk and cease to exist in very active communities because of information overload. This hypothesis is analyzed by mathematically defining a social communication network (SCN) of activities in authenticated discussion forums. We validate this model by examining the SCN using data collected in a sample of 636 online forums in Open University in Israel and 2 work based communities from IBM. The hypotheses verified here make it clear that fostering receptive participation may be as important and constructive as encouraging active contributions in online communities.”

Soroka, Vladimir and Jacovi, Michal (2004): The diffusion of reachOut: analysis and framework for the successful diffusion of collaboration technologies. In: Proceedings of ACM CSCW04 Conference on Computer-Supported Cooperative Work 2004. pp. 314-323. Available online
“While virtual communities become more and more dominant, little attention has been directed towards understanding the conditions for creating a successful community. Significant progress has been made in understanding the diffusion of collaborative tools in the workplace. We read stories about the extraordinary success of some communities, and about the harsh failure of others. This paper argues that lessons learnt from these stories should be analyzed using the theoretical foundations of Diffusion of Innovations theories, and systematized to create a set of guidelines for community creators to make their efforts more efficient. We begin by presenting a theoretical background for analyzing technology diffusion. We then analyze the stories of diffusion of ReachOut - a tool for peer support and community building developed in our Research Lab - in two different communities, using this theory. Finally, we propose a framework for planning for successful diffusion of collaborative tools, using our experiences with ReachOut.”

Jacovi, Michal, Soroka, Vladimir and Ur, Sigalit (2003): Why do we ReachOut?: functions of a semi-persistent peer support tool. In: Tremaine, Marilyn and Simone, Carla (eds.) Proceedings of the International ACM SIGGROUP Conference on Supporting Group Work 2003 November 9-12, 2003, Sanibel Island, Florida, USA. pp. 161-169. Available online
“Collaboration plays a vital role in today's new business environment. Knowledge that resides within people's heads has become an invaluable resource. Many formal tools, such as e-mail or teamrooms, have been introduced to support formal collaboration and have been studied extensively. However, support for informal communication is still in its infancy. Much work has been done to analyze the functions that informal communication plays in the workplace. Recently, several studies have evaluated the roles that instant messaging (IM) plays in similar settings. Research shows that in the workplace, IM is used primarily for work-related purposes and accelerates the completion of important business tasks. Clearly, new tools that combine both formal and informal interaction can bring organizations tremendous rewards. ReachOut is a tool for semi-persistent collaboration and peer support developed by the Collaboration Technologies Group at the IBM Haifa Research Lab. This paper studies the role ReachOut plays in the workplace. We analyzed the collaboration activity of the community of IBM Haifa Labs employees who used ReachOut for a period of two months. As a result, we summarize the important functions played by tools that bridge between formal and informal communication in a workplace-based community.”

Ribak, Amnon, Jacovi, Michal and Soroka, Vladimir (2002): "Ask before you search": peer support and community building with ReachOut. In: Churchill, Elizabeth F., McCarthy, Joe, Neuwirth, Christine and Rodden, Tom (eds.) Proceedings of the 2002 ACM conference on Computer supported cooperative work November 16 - 20, 2002, New Orleans, Louisiana, USA. pp. 126-135. Available online
“This paper presents ReachOut, a chat-based tool for peer support,
collaboration, and community building. We describe the philosophy behind the
tool and explain how posting questions in the open directly benefits the
creation, distribution, and use of organizational knowledge, in addition to
enhancing the cohesion of the community involved. ReachOut proposes new methods
of handling problems that include locating, selecting, and approaching the
right set of potential advisers. We discuss the advantages of public
discussions over private, one-on-one sessions, and how this is enhanced by our
unique combination of synchronous and asynchronous communication. We present
and analyze results from a pilot of ReachOut and conclude with plans for future
research and development.”

Cohen, Doron, Jacovi, Michal, Maarek, Yoelle S. and Soroka, Vladimir (2002): Livemaps for collection awareness. In International Journal of Human-Computer Studies, 56 (1) pp. 7-23
“With the increasing proliferation of chat applications on the web, the old
vision of "adding people" to the web is becoming a reality. Along with
collaboration tools, more and more sites offer people awareness mechanisms to
let the site visitors know about each other. This reflects the dual nature of
the web as a place for virtual meetings as well as an information repository.
While standalone chat tools became the killer application of the Internet,
site-related awareness applications did not quite catch on. In this work, we
suggest possible reasons for this phenomenon and propose a new paradigm for
awareness and social navigation. We identify three main obstacles to the
existing site-related awareness applications: high sensitivity to the "critical
mass" requirement, inflexible meeting place granularity and poor visitor
visibility. To address these issues, we extend the well-known "document
awareness" concept to a more general one that we call "collection awareness",
which better reflects the graph structure of the web. We introduce a new tool
for high-level awareness and collaboration, called Livemaps, which projects
live information onto a web site map. We demonstrate how Livemaps addresses the
obstacles we pointed out and describe a user study conducted on a "fan" web
site for the "Friends" comedy series, so as to verify whether Livemaps actually
improves social awareness.”
