The Semantria Node.js SDK by Lexalytics connects to the API to access sentiment analysis based on semantic web. Entity extraction, keyword extraction, categorization, classification, and summarization are the features included in the kit.
A year ago we asked who belongs to the API billionaires club and listed several APIs that can count their API requests in the billions. Now there are many more API billionaires serving billions of requests every month. There is also a class of eight companies that are serving in the billions every single day, as shown in ProgrammableWeb Founder John Musser's talk today at Glue.
