3d Visualization of Semantic Data using MS-Kinect

Posted in Coding, NLP, Personal, SemanticWeb at 1:02 pm by elliot

Here’s a fun little demo app myself and a co-worker built:

This application leverages the MS Kinect to manipulate 3d visualizations of social media data. The application tracks 3d motion of a person’s hand, using it as a virtual mouse cursor.

Social media data mined from tens of millions of news articles and blog posts over a period of 1+ month, using natural language processing algorithms to analyze article/blog contents, identify named entities and trends, and track momentum over time.

Info on this app:

  • real-time 3d visualization of social media data, represented as a force-directed-graph.
  • social media data was mined from tens of millions of news articles and blog posts over a 1+ month period.
  • news / blog data analyzed using natural language processing (NLP) algorithms including: named entity extraction, keyword extraction, concept tagging, sentiment extraction.
  • high-performance temporal data-store enables visualization of connections between named entities (eg, “Nicolas Sarkozy -> Francois Hollande”)
  • system tracks billions of data-points (persons, companies, organizations, …) for tens of millions of pieces of content.

This is an example “20% time” employee project at my company, AlchemyAPI. We do fun projects like this to spur the imagination and as a creative diversion. Other projects (which I’ll get around to posting at some point) involve speech recognition, robots, and other geektacular stuff.
