Are there to day any concept mining open source tools available? I have only be coming across like Leximancer, which although seem to fit the role is not open source and quite expensive for a undergraduate student. I have been unsuccessful so far since the word 'concept' on both google and google scholar seems to be un-matching what I want.

  • I do not have much idea about concept mining, but as a data miner, I usually use WEKA. Is it not appropriate for your work? – Matin Kh Dec 02 '12 at 05:26
  • Unfortunately no. For starts the purpose of the concept mining to my needs is to apply on text mining to extract concepts, I don't think weka is targeted to that but to data mining, that is, more into the structured part I believe. – Oeufcoque Penteano Dec 02 '12 at 05:29
  • I think you need to explain, clearly, what a 'concept mining tool' *is*, and perhaps (if possible) what sort of input you expect and what sort of output you'd expect. – David Thomas Dec 02 '12 at 11:38
  • I linked the words concept mining on my original question to the wiki definition and provided an example tool.. – Oeufcoque Penteano Dec 02 '12 at 23:44
  • This sounds to me like topic modelling + graphing. Latent Dirichlet Allocation (LDA) is a common method. I've used gensim in python but there are other implementations (scikit-learn in python, Mallet, Apache Mahout). For graphing, gephi is a justifiably popular standalone open source tool. – MattBagg Dec 04 '12 at 02:01

It seems to me you need a text mining tool for clustering. RapidMiner has an open-source, Java based Community Edition which has several extensions (Text Mining, R, etc.). In addition you can develop and integrate your own algorithms too.

Moreover Rexer Analytics offers a comprehensive data mining survey annually, you can call for reports for free.
