The Microsoft Cognitive Services Academic Knowledge API returns information from the Microsoft Academic Graph (MAG) which is an entity graph that models academic publications. This API offers 3 main features: interpreting a user query string, evaluating and returning Academic Knowledge entity results, and calculating a histogram of the distribution of several attributes contained in the response (such as citation distribution per year for a given author). Currently, a free plan that limits calls to 10,000 transactions per month is available. The Academic Knowledge API is REST based, returns information in JSON format, and uses API Keys for authentication.
A whopping Thirty Two APIs have been added to the ProgrammableWeb directory in the last few days in categories including Machine Learning, Sentiment, Payments, and Sports, among others. Highlights include APIs from Microsoft, IBM Watson, Square, and W3C. Here's a rundown of the latest additions.
