I've been playing around with Mathematica looking to see its text mining capabilities. I've mostly tried to use FindClusters. However I seem to have a disconnect on what I'm trying to do and what the system is trying to do. One thing I'd like to do is document clustering. I have a number of files each representing a document. I'd then like to have the documents clustered together based on similarities in word usage. This is how I've approached it thus far: dir = SetDirectory["Projects/data/19960820"]; files = FileNames["*.xml"] documents = Import[#, "Plaintext"] & /@ files However, whenever I run operations on it, weird things happen. For example when I perform FindClusters on it: Framed[Column[#]] & /@ FindClusters[documents, 20] I get the result: {<<1>>, <<1>>, <<1>>, <<1>>, <<1>>, <<1>>, <<1>>, <<1>>, <<1>>, <<1>>, <<1>>, <<1>>, <<1>>, <<1>>, <<1>>, <<1>>, <<1>>, <<1>>, <<1>>, <<1>>} Can anyone give me pointers? I'm pretty new to Mathematica and would love the help. Also, does anyone have resources / information on text mining in Mathematica? Thanks.
