Introduction and Goal

This is the third workshop we are organizing on the topic of collaborative
information retrieval. The first workshop, held in conjunction with JCDL 2008,
focused on broad topics and sought to establish a vocabulary for discussion
about collaborative information seeking, to identify work practices and
disciplines that might benefit from collaborative information seeking,
and to establish a community of researchers with related interests. The second
workshop, held in conjunction with CSCW 2010, built on the previous results, and
focused on issues of communication and awareness in support of collaborative
information seeking.

Our goal in this third workshop is to focus on algorithmic and other software
issues related to information seeking in a collaborative setting. We would like
to explore a variety of algorithms for mediating collaboration, and also to
examine how different user interface elements can be used to support associated
activity. Algorithmic aspects will include the coordination of input from
multiple people, fusion and distribution of search results, and modifications to
ranking algorithms based on group-specific information. Interface aspects will
include support for awareness of individual and of group activity, role-specific
interfaces, support for communication among collaborators, and support for
transparency of search algorithms to foster a better understanding of the search
space. It is also important to consider the effect that the starting context
(e.g., IM chat, discussions in a social network, transitions from single-user
to collaborative search, etc.) has on the algorithms and on the UI.

For more information, please see the Call For Papers at, which also includes a Demo session during which
participants are encouraged to demonstrate interactive collaborative information
seeking systems.

Call for Papers

Support for explicit collaboration is an essential part of many information
seeking activities. Explicit collaboration differs from recommendation systems
and collaborative filtering in that the people engaged in information seeking
have an explicitly shared information need. Hence, rather than inferring
similarities of intent, the system is free to mediate the sharing of knowledge
and division of labor. In the last few years, several research groups have
pursued various issues related to collaboration during search, including support
for awareness, algorithmic mediation, conceptual and software frameworks
for collaboration, and collaboration through a range of different devices.

Explicit collaboration implies a certain emphasis on interaction. The system has
to not only communicate search results to the user, but also mediate
communication and data sharing among its users. There are new algorithms that
need to be invented that use inputs from multiple people to produce search
results, and new evaluation metrics need to be invented that reflect the
collaborative and interactive nature of the task. Finally, we need to integrate
the expertise of library and information science researchers and practitioners
by revisiting real-world information seeking situations with an eye for shared
information needs and explicit collaborative search.

We are looking for several kinds of submissions for the workshop.

- Position/work in progress papers, four to six pages in length in the standard
ACM format, the describe work related to collaborative information seeking.
Papers will be reviewed and a few will be selected for presentation; the rest
will be invited to submit a poster instead. The submission date for papers is
June 29th.
- Posters will present late-breaking or just-starting work in the area. Poster
submissions should be two to four pages in the standard ACM format. The workshop
schedule will include time to view and discuss posters. The submission date for
posters is June 29th.

- Demos will show working systems that support collaborative search or other
information seeking activities. Each accepted demo will include a plenary
presentation slot of 15-20 minutes, during which significant aspects of the
system can be described and demonstrated. We will also set aside time for a
session (analogous to the poster session) during which participants could
interact with the demo presenters and their systems. Those interested in
participating in the demo track should submit a two to four page paper in the
standard ACM format that will describe key aspects of the system and how it
supports various aspects of collaborative search. These papers are also due on
June 29th. In addition, because system building is sometimes unpredictable in
the amount of time involved, to help us plan the schedule, we would like to
receive an interim progress report from those intending to participate in the
demo track some time in early September. Such a report should consist of a
series of screenshots or a video screen-cast (or even a link to a working online
system!). We'll settle on an exact date once we see how many participants we
have in this track. Demo acceptances are contingent on having a viable system
available in time for the workshop; if participants are unable to get a system
ready in time for the workshop, we will reclassify the submission as a Poster.
