IBM Watson Discovery Reviews Summary
Author infoRatingReview Summary
Sales Director at Kukac4.0I use IBM Watson Discovery primarily with IBM Watson Assistant to enhance customer interactions by retrieving product information. Its conversational AI is valuable, but pricing needs improvement, as customers shifted due to the costlier version required for advanced use.
Research at a university with 1,001-5,000 employees4.0I use IBM Watson Discovery to assess model accuracy. Its Watson Suite integration and Assistant capabilities are valuable, though the newer version is harder to train. Setup is simple, it's stable, scalable, and support is good.
Founding partner at Proxima TI3.5I value its entity extraction and content crawling. However, it demands significant memory (over 100GB for my 100GB index). While good for PoC, customer service slowness is a concern. I rate it 7/10.
Research at a university with 1,001-5,000 employees4.0I value this solution for its help desk use, language support, and scalability, extending our service availability. Setup was straightforward. While flexible, it needs more effort for specific use cases and prebuilt models. I rate it 8/10.
