Semantic Discovery

SemanticHacker.com is home of the TextWise SemanticHacker API and we're bold enough to call it the world's first open API for semantic discovery.

Semantic discovery is a way to find information without knowing explicitly what you're looking for BUT "you know it when you see it." Semantic discovery does not punish you for using the wrong keywords.

We built the API for clients and users to actively engage with our core technology - Semantic Signatures®. See our Semantic Signatures® in action on the right.

Simplified Semantic Signature®
Semantic Signatures® are built from weighted concepts. This simplified display shows the concept on the left, with its respective weight on the right. The weights represent the significance of ALL topics in the block of text. For the purpose of this demo, we are only displaying the top 5 concepts. Also, the weights have been placed on a 1 through 100 scale, 100 being the highest significance possible.
Related Wikipedia Articles
These are the most semantically related articles to the given input text using Semantic Signatures® technology. We have created an index of Semantic Signatures® with all 2+ million articles of the English Wikipedia. Dive deeper into our work with Wikipedia relations by installing the Wikipedia Extension Demo.
