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.
The following is a list of SDKs from our SDK directory that matched your search term. Though your definition of an SDK may differ, in our world, we define SDKs as platform- specific tools for consuming existing APIs of the sort we list in our API directory. For example, the Ruby SDK for consuming the Twitter Ads API. If you think an SDK, API, or other asset is missing from our directory, be sure to check our guidelines for making contributions to ProgrammableWeb.
