It's easy to use, it has an amazing documentation that helps you understand how things work! I found some bugs in certain modules but they were fixed quickly by their support team when notified about those issues so no real complaints there either way :) Highly recommended if your looking into this software or already using something else check out its competition though as well - what are other options? As of now we're doing research with our customers data sources (customer-facing databases), helping them build models faster than otherwise possible through machine learning techniques such us classification algorithms like tf idf etc., while still providing human oversight where needed! This is an easy to use tool that is very intuitive. I have used other similar tools and this one is easy to use and most importantly it is free to use. I have used the tool for a while and the support team is very active and helpful. I have no complaints about this tool. I highly recommend this tool to anyone who is interested in ontology building. I have been using this tool to create ontologies for my research.
