How to calculate term frequency and inverse document frequency -tf.idf

[noraz]

Hi,

I'm building a small information retrieval (IR) application using VB6. I'm stuck at the calculating the tf.idf part. I've google for the solutions/codes, but didn't find anything in vb6, except other languages such as phyton etc (which I'm not familiar with). I'm also a beginner programmer in vb6.

If someone could show me the sample code or have knowledge on such links that provided the solution, please let me know. Need help here.Thanks in advance.

Here's the wikipedia on tf-idf:

Here also is some C# source code that does the job:

You might be able to get some ideas from that.

To do it yourself, first take the mathematical formulas and put them into a series of steps. Then attempt to program the steps one at a time. Then you'll be able to ask for more specific help.
