Watson deploys APIs to allow developers to programmatically access the semantic content (semantic data, ontologies) it collects, and to exploit the features it provides. These APIs are meant to be the basis for the development of lightweight semantic web application that exploit online knowledge.
Watson is a gateway for the Semantic Web, which has been guided by the requirements of Semantic Web applications. It provides an efficient access point to the online ontologies and semantic data. Therefore, such a gateway plays three main roles: 1) it collects the available semantic content on the Web, 2) analyzes it to extract useful metadata and indexes, and 3) implements efficient query facilities to access the data.
With Pokémon GO seemingly taking over the world as players walk around in search of the virtual creatures, one developer used the Watson Visual Recognition API to analyse screen shots of the app to locate nearby Pokémon, winning Best Use of Watson challenge at the AT&T Shape Tech Expo Hackathon.
The DigitalOwl Text Similarity API allows developers to programmatically evaluate the semantic similarity of two articles. Similarity is expressed as a number. These articles may be submitted to the...
