"Determine text similarity?"

Legacy User

Hi,

is it possible to use RapidMiner to determine the similarity of two texts (i.e. using cosing similarity)?

I played around with RapidMiner and the text plugin. I managed to create word vectors using TextInput and applied StringTokenizer, EnglishStopwordFilter and PorterStemmer.

但现在我卡住了。如何can I compare two text files and determine their similarity?

I'm thankful for any hint!

Hi,

did you try out the operator ExampleSet2Similarity? If you search for "similarity" in the field below the operator groups in the "New Operator" tab or in the text field of the "New Operator" dialog, this (and other similarity related) operator should come up...

Cheers,

Hi,
thanks for your answer.

I tried that, but will give me an illegal argument exception: null or zero length argument @ ExampleSet2Similarity

如何erver, within DataStatistics, I have output which looks like this:

#1: authorit (real/single_value): avg = 0.09033030954895138 +/- 0.0; unknown = 0.0 #2: sourc (real/single_value): avg = 0.30110103182983794 +/- 0.0; unknown = 0.0 #3: data (real/single_value): avg = 0.5419818572937083 +/- 0.0; unknown = 0.0 #4: alia (real/single_value): avg = 0.030110103182983794 +/- 0.0; unknown = 0.0 #5: system (real/single_value): avg = 0.030110103182983794 +/- 0.0; unknown = 0.0 #6: record (real/single_value): avg = 0.06022020636596759 +/- 0.0; unknown = 0.0 #7: trust (real/single_value): avg = 0.06022020636596759 +/- 0.0; unknown = 0.0 #8: motiv (real/single_value): avg = 0.030110103182983794 +/- 0.0; unknown = 0.0 #9: patient (real/single_value): avg = 0.030110103182983794 +/- 0.0; unknown = 0.0 #10: heath (real/single_value): avg = 0.030110103182983794 +/- 0.0; unknown = 0.0

My process looks like this:

Hello,

hmm, I just tried that myself with a data set delivered together with the Text plugin and everythings seems to work normally. Here is the process:
