Issue with sentiment analysis using AYLIEN extension

h_jernstrom

I intend to run a sentiment analysis on 25000 Tweets stored in an Excel file, to obtain the sentiment and polarity values. I try to do this using the AYLIEN extension 'Analyze sentiment'. Yesterday I successfully analyzed some of the Tweets, but today I only get questionmarks in the result field for sentiment and polarity. I have tried some of the actions previously proposed in the community such as changing 'sentiment mode', and it is not an API issue as my Tweets are already in an excel file. Can it be related to my license? I only today upgraded from free to educational version, as I thought the 10 000 row data limit was the issue. It still does not work though. What is strange is that it worked fine just yesterday. Is there any other viable solution? I'd be really thankful for any input or suggestion! The XML process and process design is posted below (the red error on the last operator was there also yesterday, I could still run it).

It sounds like you have exceeded the number of records that you can process using the free version of the Aylien API.  They limit it to a certain number per day/week/month.  You'll need to check their site for the latest details, and if you have more records that you need to score, you may need to upgrade to a paid subscription.
