The features are pretty great for extracting n-grams or bigrams (word sequences of 2 words). It handles very well unigram extraction as long it's not too frequent in your text files/data sets like dates which I had an issue with at first but quickly solved by enabling date filters during training stage so now this works perfectly fine! If you're looking into NLP then definitely look no further than colibris core - its free & easy enought even newbies can use without any problems if they have basic knowledge about programming languages such us python etc.. I like how it's easy for me as an individual developer or small team of developers (2-3) with limited resources / time/budget but big ideas in mind! The UI could be improved - sometimes there are issues when you have more than one window open at once so some parts can become hard to see if they're not near your main focus area. It helps us understand what our customers want by looking into their social media activity & engagement levels across different channels.
