Metacortex explanation

Imagine if Hacker News was a large company, with many remote workers and dispersed teams:

  • How would you identify duplicate work?
  • Who has expertise in the area you need help in?
  • Where is documentation about an internal project?
  • How is company moral?
  • How do people feel about Java?
  • etc, etc...

That's where Metacortex comes in!

Just send discussions to the ingestion API, it automatically identifies expertise, ranks content, track moral, and more. For more technical details, see how it works.

In addition to search, it's also possible to use the APIs to integrate into third party applications, such as:

  • Duplicate effort notifications
  • Employee satisfaction monitoring
  • Insider threat detection
  • Team management

We achieve this by categorizing experts online and analyzing their discussions through data mining, sentiment analysis, and more generally machine learning. We call our algorithm ExpertRank, paying homage to PageRank.

Note: The current system only has Hacker News comments, these only consist of a few comments a week (max) for the typical user. Imagine this system in a company, with hundreds of more comments per user per week. The systems accuracy grows substantionally.


We have years of experience working on high priority problems at Fortune 100 companies as full stack engineers and data scientists. We often wrangling large amounts of data with the latest technology.
