- texti am using rapidminer to compare the similarity between two text fields in two sheets in same excel file using cross distance, as i want to compart one request will all referernce to return the similarity value by cosine similarity, the problem is the distance returns as question mark '?' without knowing the reason

Hi @asafwat,
I think I found elements of answers (now calculated distances/similarities have numerical values) :
In the documentation of the Cross-Distances operator it is said that :
"Please note that both input ExampleSets should have the same attributes and in the same order".
So you have to use a Superset (cf documentation of this operator) operator to feed the req and ref ports of the Cross-Distances operator with 2 datasets which have strictly the same attributes.
Moreover, I made some modifications in your process :
- in the Process Documents from Data operators : vector creation -> Term Occurences.
- in the Tokenize operators : mode -> non letters.
The process :

Hi (one more time ...) @asafwat,
Just a (last ?) little advice, you don't need to specify that an attribute is "regular" in the Set Role operator :
By default, RapidMiner set automatically an attribute as "regular"...

Hi @asafwat,
Are your attributes "numerical" ?
Can you share your dataset(s) in order we can reproduce what you observe ?

Hi again @asafwat,
I have difficulties with your CSV file, can you send me your original Excel file by :
- zipping it, then, attaching it to this post
- sending your Excel file on Google Drive and then copy and share the link here in the forum

Hi again (and again) @asafwat,
Can you send me your Wordnet dictionnary too (by zipping it for example).

Hi @asafwat,
I think I found elements of answers (now calculated distances/similarities have numerical values) :
In the documentation of the Cross-Distances operator it is said that :
"Please note that both input ExampleSets should have the same attributes and in the same order".
So you have to use a Superset (cf documentation of this operator) operator to feed the req and ref ports of the Cross-Distances operator with 2 datasets which have strictly the same attributes.
Moreover, I made some modifications in your process :
- in the Process Documents from Data operators : vector creation -> Term Occurences.
- in the Tokenize operators : mode -> non letters.
The process :

Hi (one more time ...) @asafwat,
Just a (last ?) little advice, you don't need to specify that an attribute is "regular" in the Set Role operator :
By default, RapidMiner set automatically an attribute as "regular"...
