please help me how i can make use of PyKE to solve my problem

[krishna]

hi all,
this is krishna. i want to build an inference engine to draw
inferences from email conversations for forensic analysis. How can i
make use of PyKE? is there any other better tool? How ever i am new to
this python language. Please give your suggesions.

Thanking you.


Your's Sincerely,

I have not done any work in forensic analysis of email messages, so it is difficult to recommend tools.

So all I can do is provide some broad, general advice:

• If you are new to Python, I would recommend that you learn it.  You will find that it is generally much easier to write programs in Python than most other programming languages.
• PyKE provides Prolog-like inferencing, but does not try to be a pure logic programing tool (like Prolog does).  Rather, it is designed to allow you to use PyKE where logic programming makes sense, and to also use Python where standard imperitive programming makes sense; and to then be able to easily integrate these two very different programming methodologies.
• I should think that PyKE would work well if you already know what patterns you want it to look for -- even if these patterns are quite complicated.  It is not, however, designed as a self learning tool -- meaning that it is not designed to be able to figure out the solution to problems on its own.
• While PyKE should work well for email analysis based on looking for certain keywords in the text, it may not be the best tool if you want to develop a natural language understanding system that can fully parse and understand the text of the email.

I hope that this is helpful.  Good luck to you!

Dear Bruce,
Thank you very much. I want the system to

1. Perform a semantic search over the email corpus
2. understand the emails content
3. draw useful inferences from multiple emails(considering actual body
of the email + metadata like sender id ,reciever id, time,date
...etc).

I hope my first task can be done easily using PyKE. Now i am doing
the semantic search using LUCENE Java API and WordNet.

To build commonsence reasoning i have gone through OpenCyc. But it's
inference engine is not an open source.

Thank You very much.
