PERSONALIZED COLLABORATION
Jozef Tvarožek
Our highly networked and computerized society facilitates effortless contact among different
people, people that did not meet before and perhaps never ever meet in person, and
they communicate with one another simply because it is easy and mutually beneficial.
Research studies indicate that numerous tasks are achieved more effectively by collaboration
of a group of people toward a common goal.
In this chapter, we explore individual components of computer-supported collaboration
systems, namely we first examine typical types of collaboration and the system’s architecture.
Then we look at the group formation process from assembly of groups to evolution
into effective virtual teams, and aspects of incentives and reputation mechanisms.
Finally, we review algorithmic approaches to modeling human-computer relationships
and describe an activation network-based mechanism that can be used to perform effective
human-computer social dialogues.
We are interested in methods and processes that make the collaborative experience
user-centered and beneficial for the individual user i.e. personalized. The principles are
demonstrated here mainly on computer-supported collaborative learning systems (educational
domain), however the same principles of collaboration can be successfully used in
other contexts such as in workplace setting, and we try to mention similarities and differences
to these systems through the text.
9.1 Collaborative Systems
We define the concept of collaboration very broadly as a joint activity of a group of entities
toward a shared common goal. Next, we analyze collaboration on different dimensions
and present exemplary instances of each type.
9.1.1 Types of Collaboration
Face-to-face vs. Computer-mediated
Approaches to face-to-face collaboration have been used since a long time with activities
such as role playing, simulations, and small-group projects. For example, in the Jigsaw activity,
a group of students receives several topics for research. Next, the group is divided into
