Question
Answering System for an Effective Collaborative Learning
The increasing advances of Internet Technologies in
all application domains have changed life styles and interactions. With the
rapid development of E-Learning, collaborative learning is an important for
teaching, learning methods and strategies. Interaction between the students also student
with the teacher is important for student to gain knowledge. In
this paper, we introduce an effective question answering Q&A system for
collaborative learning, which can act not just like a virtual teacher, but also
virtual discussion for student. With the proposed system, brings a new Q&A
system, student can attach their question when they want collaborate using collaborative
learning capitalize on one another’s resources and skills. Students can ask
their questions to the group when they want to collaborate with others, asking
one another for information, evaluating one another’s ideas, then each of the
answer will compare with encyclopedia data base.
Architecture
of Question and Answering System
ARCHITECTURE:
EXISTING
SYSTEM:
The
existing system has the option to the student can attach their questions, and
it directly check through the links, and it does not have the question answering
knowledge base concept, acquires knowledge about students and uses the acquired
knowledge. It may have the database in an article or a selected topic and it is
not updated regularly. When a new question arrives it might be trouble. The students cant attach their questions to the group when they
want to gaining and sharing knowledge with others.
Disadvantage:
Ø It does not not have an effective question answering Q&A system for collaborative learning.
Ø Interaction
of students and a teacher address a problem, the teacher cannot constantly
online every time, and it is not possible for the teacher to deal with lots of
question from students.
PROPOSED
SYSTEM:
E-learning
system, which is proposed here is based on knowledge base system which allows
acquires knowledge about students and uses the acquired knowledge In
this research, a system for online automatically answering students’ questions
in the collaborative learning environment has been designed. The system
operated upon the question answering knowledge base. In the knowledge base,
pairs of question with its corresponding answer (Q&A sets) were collected
through the process of students asking questions and other students will
response the question with answering and evaluating one another’s ideas by
vote. This representation is then compared with the representations of
Wikipedia data base.
Advantage:
Ø The
Question answering knowledge base is the main advantage because it will update
whenever the new one come.
Ø This system has an effective question answering Q&A
system for collaborative learning, which can act not just like a virtual
teacher, but also virtual discussion for student.
MODULES:
- Student
Agent Q
Student agent Q- It is interface between
student and the system. Student can send his or her question and receive
answers. Question analysis, query generation.
Q&A Browsing Component-when student meeting some difficulties or having no
difficulties, a student can see what problems other students have encountered
in learning now and in the past and see the answers or solutions the teacher
offered by browsing the knowledge base.
Answer Generator
is Several interfaces have been designed, to let students and teacher is able
to interact with the system. The interfaces for the student to ask question and
get answers
- Student
Agent A
Is the component interface between
student and the system provides an answer and voting question.In this component
also provide similarity machine to match student answer with Wikipedia
database, to ensure the answer considering biggest vote not necessary correct
answer.
- Instructor
Agent
Q&A Acquirer -If there is an
unanswered question, the questions will temporarily stores at this component.
When the teacher gets online, and then will manually answer the question with
an interface (Instructor Agent). A new Q&A will be formed and saved to the
Q&A knowledge base, after a question replied by the teacher.
- Question
Answering Knowledge Base
A
knowledge base provides a means for collected, organized, shared, searched and
utilized information. Q&A knowledge base is a knowledge base where
questions corresponding with answer. The knowledge will be accumulated and
rich, through the process of student question answer and manually teacher
answer.
