Dear Kais,

System type (1) sounds interesting and I'll be glad to help in collecting 
fact-based questions and answers that are backed with verse(s) as long as it's 
not related to Fatwa, agreeing with Abdul-Baqi and Wajdi regarding factoid 
questions and selecting simple questions from the proposed websites.

Regarding what Eric said:
As Kais said a QA system that can do what a concordance cannot is the prefer 
objective, providing a simple answer backed by a Qur'anic verse is a great idea 
to start with.

Finding relationship between verses is something that needs to be focused on, 
and it could be trained according to the answers provided from the training set 
you are planning to use. Therefore, if we have a question answered by 2 to 3 
verses these verses could be considered highly related, which could help in 
answering other related questions.

Subject: Re: Advice Required - Dialog System for the Quran

Hello,

This discussion thread is getting quite interesting indeed. What do
you all think of START - the natural language question answering
system?

http://start.csail.mit.edu

I think it's pretty good for simple facts, especially as it usually
cites the original source resource for each answer. With regards to a
Quranic QA system, I think that so far the general consensus on this
mailing list is that there could be two types of system:

(1) A very basic fact system, which can answer simple questions from
knowledge in the Quran, backed by Quranic verses.

(2) A much more advanced system, which combines the Hadith, Quran, and
other parts of the Islamic faith to give fatwa-style answers using
advanced inference and automated deduction.

Well, we have to start somewhere ... so I'm keen to focus on system
(1). The question for me is, would a simple fact system still be
useful, without advanced inference? From a practical perspective, I
believe that it would be, although of course not as useful as system
(2). A very-simple QA system might be useful for students, younger web
users, and the general public who might be interested in simple
questions about Islam. Probably not so useful for those already
familiar with the Quran and the religion in more detail and are after
finer clarification. From an Academic perspective, system (1) is also
very useful because:

- It might be one of the first few attempts at a Quran QA-system
(would give a baseline for future research in this area).
- It would be interesting to know how the genre of the Quran affects
QA in general, i.e. is there anything special about this domain? Is QA
for the Quran the same or any different from general QA?
- Given that the Quran is highly studied (and now also highly
annotated linguistically) does this extra information help beyond
basic keyword search?
- This simple system is probably a step in the right direction for a
more advanced system (2)

Based on recent discussion, I would suggest that a good starting point
would be a simple QA fact system. Note that "simple" here refers to
the system from a user's perspective. From the perspective of those
designing and building such a system, things which look "simple" to a
user can be very hard indeed in the field of AI :-), if not sometimes
nearly impossible!

Would anybody be interested in helping to compile a list of basic fact
questions about the Quran, backed by specific verses? Here are some
simple fact-based questions that come to mind:

- Who is Allah?
- Who was Muhammad?
- What is Islam?
- Which prophets are mentioned in the Quran?
- Is Solomon mentioned in the Quran?
- What does the Quran say about Jesus?
- List the religions mentioned in the Quran.

(Inspired by http://start.csail.mit.edu)

The good thing is that once we get a basic system up online, we can
start to monitor the system's log files to see which questions are
most frequently asked (we would expect a Zipfian distribution) and we
can later tune the system to give good responses to the most common
questions. Hopefully each of these questions could be answered via an
extract of a relevant verse from the Quran (within reason). Ideally, I
would like to compile a list of hundreds (or even possibly thousands)
of questions with simple answers from verses of the Quran.

After that, there could be lots of other possibilities. Given a large
list of question and answers, this could be the final knowledge base,
and we map new questions to existing answers. Otherwise, given a large
list, there may be a reasonable way to think about automating the
process of question/answer extraction to a reasonable level of
accuracy - so that future compilation of the knowledge base might be a
case of manual verification of automated suggestions.

I'm looking forward to any suggestions on the first stage of this new
project: constructing a large list of simple questions and answers
relating to verses of the Quran.

Kind Regards,

-- Kais
