Hi Farhan,

did you download the Wordnet extension? If not please go to "Help>Updates and Extensions" and search for the Wordnet extension.

After downloading and restarting you should be able to find the new operator "Extract Sentiment (English)".

Cheers,

Nils

i have followed the same instruction as you have said in your post. Everything is accordingly but the extract sentiment operator is asking for the dictionary as an input. which when i provide wordnet3.0/ dict it gave me an error message as:

--------------------------------------------------------------------------------------------------------------------------

Reason: map failed

The given resource could not be read and parsed.please make sure the file is well formed and parsing parameters are specified correctly.

cause : Open WordNet Dictionary

---------------------------------------------------------------------------------------------------------------------------

Moreover in the operator information of extract sentiment does not include the details of the required input for the specific operator.

Kindly help me for the same.

Thanks in advance.
