LSA - Matrix Transformation causes Error #29

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Hi,

I'm trying to use the LatentSemanticAnalysis to compute the similarity of 
different texts (see attached maven project). However, I get a 
java.lang.NumberFormatException on the String "0,273696". Obviously, the comma 
is causing the problem. But how the comma comes to exist in the first place is 
unclear to me.

So far I was able to trace the error to the transformation of the 
termDocumentMatrix. The matrix itself looks fine (see attached file). But the 
transformed variant suddenly contains floatingpoint values with commas instead 
of point (see attachment).

I hope you can help me.

Yours,
Laura

This problem seems to occur within the sspace package that DKPro Similarity 
only uses.
It would be better to report this problem there:
https://github.com/fozziethebeat/S-Space

Setting the status to "invalid" which doesn't mean this was an invalid request, 
but that this is no fixable within DKPro.
