Abstract:
The modern learning practices are strongly based on Interactivity. Teachers
and learners get involved in a complex and rich process of understanding.
A central tool for this process is an environment that supports the formulation
of questions and answers.
Today, question and answer services have a certain degree of automation,
usually related to such areas as: indexing, information storing and automated
search for resources.
Three aspects of these services are still open. The first one refers
to the system’s ability of getting a perfect “understanding” of the content
of a natural language written text. The second one is related to the system’s
capacity of “choosing” the right person to answer some question.
Finally, the last one regards the system’s ability to answer the questions
itself. In practice, human agents have to solve all these problems.
The amount of messages (questions, answers, opinions, etc) recorded
in cooperative environments reaches intractable dimensions, without automated
support. To address this problem, we are developing an environment called
QSabe II: A Cooperative Service for Knowledge Appropriation and Diffusion
Using the Internet.
This environment is based on the QSabe system, an intelligent system
for questions routing. Using the groupware metaphor, the QSabe agent acts
as an interpersonal assistant, allowing each member of the group to participate
in the process, formulating or answering questions. The agent uses both
text comprehension techniques and machine learning theories. In fact, the
system is able to interpret the questions about a pre-established subject,
and it is capable of dynamically learning the profile of the collaborator
user (the expert in certain subject). This way, the system can route the
message to the most convenient expert.
The QSabe II enhances the functionalities of the existing system. The
new system has the following requirements: extract and compare the questions
profile; identify semantics based on onthologies and natural language processing;
capture the degree of difficulty of each question and capture the degree
of ability of each responder.
