We are delighted to announce that, as of today, our question-answering platform is now available for anyone to use via our API. Free accounts can now be set up immediately without any approval process.
There are two main services:
Our 'Direct Answer' API service allows any application connected to the internet to answer their users' natural language questions on any subject. Examples of such applications are search engines and applications running on mobile devices.
To make use of this, the developer simply passes their users' text questions to the True Knowledge platform in the form of an encoded URL. The system then automatically responds using XML containing a straight-forward text answer which can then be displayed to the user.
Various options allow additional information to be returned as well, including images and associated links relating to the answer or the entities recognised in the question. These can be optionally used by the calling application to create a richer user experience.
In the event that the True Knowledge platform cannot understand or answer the question, the response says so and the calling application can present alternative content. An example of an application that makes use of the Direct Answer service is Quizbot which is a simple one page website built on this API service.
The second API service is the Query service. This allows calling applications to bypass the natural language layer and directly query the True Knowledge platform using our own language-independent query language.
The True Knowledge platform contains almost 140 million facts about the world including extensive common sense, lexical and factual knowledge. This resource is also growing rapidly, powered by user, company and mined knowledge and through inference trillions more facts can be exposed by our platform. There are thousands of applications that can be built using our query service and a few examples are shown at http://www.trueknowledge.com/api/examples/
For the Query service in particular we anticipate that users will find applications of our technology that we haven't anticipated and would love to hear from users about what they are hoping to achieve.
