Errors Twitter data, Suddenly Attribute Label Missing, Inside Cross Validation, SVM and Apply Model
Hi everyone, I'm doing my process in rapidminer for my thesis, I have little time and I'm desperate need for help. I beg you please 
I have no one to help me with rapidminer, everyone else I know uses R or Python.
I am getting an many errors in my process:
- First, Inside the 'Cross validation' operator it does not identify my attribute as a label. For test, I've added a 'Set role' operator towards 'SVM' operator and still doesn't work. Then for training, also 'Performance' operator doesn't recognize my label anymore.
- When I go back to process and add 'Set role' operator again before 'Cross validation' it doesn't work as well. In the list, my attribute is not listed anymore for some unknown reason, while in the ealier steps of the process it does show.
- Lastly to make even worse the 'Apply model' also does not recognize my attribute (also tried to add 'Set role' there). The attribute label "text" is just gone from the list.
I'm analyzing text from twitter. But since I had several queries to analyze for my research, I didn't get them from Rapidminer,instead I downloaded the data from twitter app developer and added to rapidminer. I post my xml process here.
Please help.

- I'm trying to analyze passengers sentiment in the airline industry and find out what kind of insights can social media text mining from twitter bring;
- I cannot focus in only one company, so I selected 6 popular airlines;
- Rapidminer Twitter search operator only allows one query to be searched at a time. So I just extracted the data from Twitter Api directly, saved in CSV files and uploaded to Rapidminer;
- Then, I used the 'Append' operator to connect them all;
- I have provided a label. Set role operator is there. You see... The process was working fine til 'Process documents' operator;
- Inside 'Cross validation', SVM and 'Performance' does not recognize my label anymore. Rapidminer suggested me to fix it, so it add another 'set role' operator, which does not help.
- I've been trying for days to solve this, but I'm running out of time. What I did then, I opened the extracted CSV from each airline, and as you may know, it's full of useless attributes. So I deleted all of them to see if it worked (This may have been done, but I'm learning, sorry). And the same problem remains.
- Should I have kept the spreadsheet as it was? (Full of the other attributes - There were almos 80 funky attributes)
Dear Scott,
Thanks for your answer. Indeed, this funky attribute I don't know where it came from. So I decided to change some things in my process in order to try to solve this. So I decided to remove all weird attributes manually and retrieved again into rapidminer into a new process.
So far was working ok, but now the SVM operator does not recognize my one single attribute again saying that the example set has no examples. I dont get why this happens since the data is connected. I attached the data with all spreadsheets (but in rapiminer I used the 'Append' operator to bring them all together, I hope to solve this asap.:smileyembarrassed: Thank you

@alinebora You do not provide a label. What are you trying to train all these text tweets too? Negative/positive sentiment?
Thank you so much for your time. I truly appreciate, you guys are the only helo I can count on.
I hope to solve this. It's for my thesis, I should've started writing the analysis last week, but I've been having this problems... And I have to deliver August 31st.
@alinebora you set the user_id as the label. There is no user_id in the CSV files you attached. Conceptually that will not work either because there are hundreds of users tweeting about some airline that the model can't find any relationships there to the user_id.
From the create document operator I see you entered some negative related tweets. I'm assuming that this is all about sentiment. If that's the case you need to create a training set with a label column that has negative or positive in it. From there you can text process the tweet and the label remains intact. That gets passed to the Cross Validation and from there you can measure your performance. Your process setup would appear to work but you're not feeding the information correctly. That's why nothing happens. That's the flaw.
If sentiment is not what you're after, maybe understanding topics that people are tweeting about, I suggest checking out the LDA operator. I believe it's in the Operator Toolbox extension. Also visit KB here for a tutorial on using the LDA operator.
See below a sample process. It uses the Retweet column as the label and trains a GLM on it. For future reference, you can Loop over the Search Twitter operator and load several search terms.

@alinebora additionally, your tokenization parameter set to 'non-letters' will wipe out things like '#airfranceisgreat or '@' symbols, stuff that might be valuable to your model. My suggestion is to look at the process I share here: http://www.neuralmarkettrends.com/use-rapidminer-discover-twitter-content/ and see how I did the tokenization and extraction of Twitter data.
Dear Thomas,
Thanks for your reply. Is it possible to search for more than one query to analyze in Rapidminer?
Perhaps, if I add the 'Search twitter' operator, run, then store individually doing the following:
1) Search the 5 times (5 different queries) to get the twitters I need;
2) Use the 'Store' operator and retrieve it in my local repository;
3) Start a new process, retrieve the 5 datasets created previously and then use 'Append' operator to merge them altogether.
Will this make it work?
Will this make my analysis possible avoiding the previous errors mentioned?
@Thomas_Ott I opened your link, but since I'm new at Rapidminer, I don't know how to read and understand a XML process as you posted
@Thomas_Ott I managed to post yout xml process in my process panel, but now I'm getting this error (Please note that I updated each connection individually to validate my credentials clicking in the twitter button and testing connection):
@alinebora double check to make sure your connection is correct. You might have to go into each Twitter operator and reselect the connection.
Hi @alinebora,
That error you get might be because @Thomas_Ott is using his own Twitter credentials (consumer and api key) to create this process. To solve that issue, you should set up yours on each Search Twitter operator. To do that, you should go to:
Connections > Manage Connections
It's a pretty straightforward process.
You must then replace the connection set up on the Search Twitter operators by the one you have setup, et voilá.
All the best,
Rodrigo.
I had done that already as you mentioned. Nevertheless, I decided to create a new connection, requested a new pin, updated each twitter search operator one by one, and now I get this error TT

@alinebora I made some tweaks. It appears that the Twitter operators you added aren't playing nicely for some reason. My guess it has to do with an encoding issue. I also disabled the store operators. They all repath to my laptop so they'd break for you. I just tested this, it works on my end.

Great job, sensei @Thomas_Ott!
Now, on a side note, I found out that having everything on a single process makes things confusing to some people, including me. What I am sharing here on a zipfile is a RapidMiner Local Repository that can help @alinebora organizing her work step by step, and make it more modular. It is not as advanced as what Thomas did, though. I might, for the sake of science, complete the process and make a new version of it.
@alinebora, I would like to point out that in the case of your research, your professors or someone else might want to take a look at your process, and for that you should share the data you got in the first place. This way to write modular and sequential RapidMiner processes helps you building a process that can read data from CSV instead of doing it directly from Twitter, and reuse everything else.
It is a good idea to categorize your data in staging (or raw data, without processing), parameters (categorical data which is the kind of data you use to perform filtering at some point), facts (data that is already processed that tells the story you want to be told), models (yes, you can store the result of your trained algorithms) and calculations (your data after you apply certain models; you can use this data for further reinforcement learning in other projects). This kind of OCD organization has saved me thousands of times in my research projects.
To use this repository, you have to uncompress it somewhere (the default place for this is the .RapidMiner/repositories directory on your home, but if you want to put it somewhere else, you can) and create a new Local Repository pointing to that folder.
Hope it helps,
Altair Employeethank you all for such an amazing RM Community response!
I have posted @Thomas_Ott's solution in the new Community Repo. You can access it directly by clicking on this link.

@alinebora I made some tweaks. It appears that the Twitter operators you added aren't playing nicely for some reason. My guess it has to do with an encoding issue. I also disabled the store operators. They all repath to my laptop so they'd break for you. I just tested this, it works on my end.

hello @alinebora - hmm the first thing I see is that your "user_id" attribute has some funky characters in it. Is this intended? It would not shock me if this is messing things up...
Second I just want to make sure that what you're doing makes sense: predicting the user_id based on the word vector of the tweets.
I can't test your process without your data set (can you post? it would be MUCH easier) but made some tweaks to your process here. Note I used the </> button to embed the XML in this post
Hope that helps?
Scott
