In the 2 previous posts we have discussed a list of API services that could be helpful for quickly starting with Making Data-Based Prediction and Image-related analysis, such as Face Recognition or Pattern Recognition.
This is my favorite topic as I’m involved into building PocketConfidant, a 24/7 counselling technology, powered by AI and psycho-linguistics. Now my purpose is to share a list of services that could help in
Text Analysis, Natural Language Processing and Sentiment Analysis.
