The Challenge: Create an Intelligent App Using the Meaning of Written Text challenged the hackathon participants to create an app that integrates operations on the meaning of text using the Retina API and offered $5,000 in cash for the winning team.

12 teams participated in the challenge. We saw brilliant hacks and our judges, Subutai Ahmad from Numenta and Alexander van Dijk from the NASA Ames research Center, had a hard time choosing the best.


The winning team

The Gumshoe team: Xander Peterson, Jesse Callwood and Stephanie Hutson


Gumshoe developed an intelligent social media matchmaking system based on semantic fingerprints. The application collects tweets, posts and other user relevant information from social media platforms such as Twitter, Facebook and LinkedIn. It then feeds the collected data through the Retina API in order to create a semantic fingerprint of each user profile. This profile fingerprint is unique for each user as it contains the contexts associated with their online presence on a fine-grained level of details. The app then matches users with other users with a similar profile fingerprint (meaning that they share similar backgrounds, similar interests), opening new opportunities for online networking, dating, employee search and much more!
