As we all know "Data mining is a collection of techniques for efficient automated discovery of previously unknown, valid, novel, useful and understandable patterns in large databases."
Nowadays, the crime rate is increasing like anything and hence to support reducing it and to make the judiciary/legal system more fast and easy "crime data mining" is often used.

Using Data mining techniques aids analysis of data related to crimes, extracts named entities from narrative reports, detect deceptive criminal identities & identifying criminal groups and key members.
Programming & coding is done day-in and day-out, algorithms are written and patches are applied to extract criminal data.

I was doing an extensive search on web data extraction tools which can replace these long coding procedures. Finally, I found a powerful software which can take care of all the above needs - Automation Anywhere.
It features Web Data Extraction with Advanced Pattern Matching technique. If there is a set pattern to the data that is to be extracted, Automation Anywhere recognizes the pattern on just a few clicks and extracts data from all the pages till the end of the list.

One can download the free trial and also get more information at: http://www.automationanywhere.com/solutions/webDataExt.htm

Thank You.
