QUOTE
An artificial neural network (ANN), usually called "neural network" (NN), is a mathematical model or computational model that tries to simulate the structure and/or functional aspects of biological neural networks. It consists of an interconnected group of artificial neurons and processes information using a connectionist approach to computation. In most cases an ANN is an adaptive system that changes its structure based on external or internal information that flows through the network during the learning phase.

In more practical terms neural networks are non-linear statistical data modeling tools. They can be used to model complex relationships between inputs and outputs or to find patterns in data.



I have been mulling on the idea of using neural nets in Human Resources in the area of resume parsing by approaching it from an angle of (text) pattern recognition ...

Comments welcome.

you would have to think about the depth of the system you want. Would it only be parsing at the syntax level, or do you want to deal with semantics as well?

And what are the features or patterns that you are looking for? Just key words?

Theres quite a lot to think about as they are many different approaches to the problem.
*
in the inital stage, i would like to go by keywords, where the net identifies some simple items like
Name
Address
Phone Number
Date of Birth

and tags them accordingly.

if they tag incorrectly i will have to reclassify the item to correct tag.

so that next time they can tag it properly.

I am still thinking about how to teach the net...


Urgh more reading to be done

Yes, it is interesting. I was planning to do my research on my Final Year Project and from what I found out the following links are using ANI:-

http://eprints.nottingham.ac.uk/621/

Because of the fact that intrusion detection systems work based on pattern based recognitions, by using a simulated human immune system which is self learning using neural networks, the barriers of ID can now be break through.

at this point i also not sure how potential viruses are detected , i belief each AV vendor has their own pattern recognition heuristics involve in this...

I've passed your question to my friend who does natural language processing.

BTW if you're looking at parsing something else, our garage sales topics could use some machine categorization smile.gif I would be happy to give you the data you need.

ah thats the keyword, why didnt it come across to me earlier...
for all i know i may be barking up the wrong tree on this laugh.gif

What is the final aim of the system?

Do you want to bin the resumes into seperate groups depending on what key words exist? Or something else?

You'd also have to first build a parser that will be able to read the resume input, and parse it into a format suitable for training the NN.

Well I have this project sitting on the shelf for many months, its to do with taking resumes of all formats (text readable ones)
and extract the useful data. As we know , many people write them in differing styles, but the general idea is

Personal Info
Education
Work Experience
Summaries (in paragraphs)

So i'd like to
1) split the data up to these categories so that its more helpful to my search
2) categorize the resumes by role (system engineer, programmer, analyst)

I'd probably focus on the IT resume sector at this moment...

Some months back it did occur to me that AI might somewhat help my efforts... I did do some of ANN pattern recognition yonks ago , probably around the time mariah carey released her first album wink.gif


* my first attempt bombed miserably, which purely searched for keywords and marking entire blocks of text based on that...
