    Hi and welcome to the community.

     

    What you need is first install the Word2Vec extension from the RapidMiner marketplace.

    Once done you'll find the Word2Vec Operator in the Operators search bar (or use the global search).

     

    You can check this excellent post by Martin on how to apply the extension:

    Hello
    Thank
    I saw the link
    Unfortunately, the pictures are not clear.
    You may want to send an image of the use of this operator to analyze emotions
    Many thanks

    Dear @khazan,

     

    the mentioned post has an attached .zip. It contains the full analysis so you can load it into your RM and use it yourself.

    Hello
    Thank you for your attention
    I downloaded the sample file to use Word2vec And I entered the RapidMiner.
    But there is an error.
    And I do not know what the process of using this operator is.
    Please give me guidance.
    thank you again    88.JPG

    Hi,

    this operator expects a collection of tokenized documents as an input. Not an Example Set.

    Hi,

     

    how many docs do you feed in? More than number of negative samples? Can you please try more?

    Only this one example from the web page of point 1

    The data is provided in one flat file for each hotel with the following structure:

    <Content>Wonderful time- even with the snow! What a great experience! From the goldfish in the room (which my daughter loved) to the fact that the valet parking staff who put on my chains on for me it was fabulous. The staff was attentive and went above and beyond to make our stay enjoyable. Oh, and about the parking: the charge is about what you would pay at any garage or lot- and I bet they wouldn't help you out in the snow!

    Hi,

     

    you need to provide more data to be able to run word2vec. A single example won't work to train the model. I've tested it and it starts to work with 5 examples.

    I copied the original record and changed something. Now the database is two *.dat files.

    After this, I get the same error...

     

    EDIT

     

    Ok, I build 5 data files and try again...

     

    Regards,

    Thomas

  • thomas_wiedmannthomas_wiedmann Member Posts: 60 Maven

    Right, with five files, the process works. I continue testing now...

     

    Thanks!

    Now I try with five small (german) Textsample and the process failed like before. Is there any lower boundary or param?
    Please explain..

    Regards

    Hi,

     

    well the algorithm itself makes only sense if you have a lot of data. Honestly it would make some sense if i add an error for less than a thousand examples. Less is usally not yielding good results.

     

    I am not sure where the exact bounday of 5 comes from though.

    Hi,

     

    Process Documents converts this into a bag of words. Please have a look on the example processes. It shows you how to do this with loop collection.

  • MartinLiebigMartinLiebig Administrator, Moderator, Employee-RapidMiner, RapidMiner Certified Analyst, RapidMiner Certified Expert, University Professor Posts: 3,533 RM Data Scientist

    Hi,

     

    please try Read Exel, Nominal to Text and Data to Documents. That should create a collection which can be handled by Loop Collection.

     

    Best,

  • Thomas_OttThomas_Ott RapidMiner Certified Analyst, RapidMiner Certified Expert, Member Posts: 1,761 Unicorn

    @khazan that error means no data is being passed out of the Loop Collection. I would put a breakpoint in on the Loop Files operator and see if data is reaching the Loop Collection.  

  • khazankhazan Member Posts: 23 Learner III

    I used but did not have any results
    Please, if there is an alternate operator for loop file, guide me.
    Please tell me how to use word2vec for twitter data? Thanks

    hello @khazan Some quick recommendations for you:
    • Post your XML process here in this thread (see https://youtu.be/KkgB5QXWXJ8 and "Read Before Posting" on right when you reply)
    • Attach your dataset if possible (use a fictionalized version if there are privacy concerns)
    • Make sure you have all necessary extensions installed (see https://youtu.be/pjBqG3xtXx4)
