I work in Text Mining and Data mining ...I Sandeep, <br />I work in Text Mining and Data mining project in a big multinational company (reInsurance).<br />To be successful in the fraud detection, the companies need to understand some key points:<br />1) it is required big investments on the data quality:<br />often the quality of the data is so poor that the entropy doesn't allow any proficient analysis.<br />2) Apply "Divide et Impera" approach: solve small sub problems, and try to merge the single solutions: often there are some predictors of fraud that you cannot see if you don't split the business process in functional process.<br />3) FORGET miraculous tools! Even for easy problem like document classification a commercial tools require so much customization that the efforts overcome the benefits!.<br />4) Entrust the data analysis to serious consultants able to customize algorithms and technics for the specific domain.<br />Let me bring to you attention my blog:<br />There is not a specific tool for large dataset. To classify it extract a reasonable sample set and test on different test set extracted randomly!<br />Of course before to do that you need to check the homogeneity of your data: (sometimes for problem having dimension >3 are useful SOM like kohonen maps). <br /><br />To be honest I don't see great problem to classify large data set. Some problem could arise when the dimension of the problem is great (in this case you could reduce the number of features with some algo like C4.5 or PCA). Yuo can find most of the algo I mentioned for example in WEKA (not useful for productive tool, but is pretty good to evaluate the benefits of the common algo).<br />Let me bring to your attention my new blog site:<br />http://textanddatamining.blogspot.com/Cristian Mesianohttps://www.blogger.com/profile/04880057603671195464noreply@blogger.comtag:blogger.com,1999:blog-2955384208560065258.post-49949821991531836242011-06-22T22:15:18.979+05:302011-06-22T22:15:18.979+05:30This is really very good.
