The first speaker is from Blekko.com, which he says “is thought of as the third search engine” in the US market.

Weblib.com describes itself on its site as “Natural Language Processing Tools and Customizable Knowledge Bases for Semantic Search and Discovery Applications.” Thomas talks about OntoFind and semantic search, which is a search that produces “meaningful results even when the retrieved pages” contain none of the search terms [latent semantic search!].

ScienceScape.com is designed to help scientists follow science. It diagrams publications on a topic, and applies article-level metrics. It’s focused on the undergrad and graduate research markets. It integrates genomic knowledge plus much more. It lets you see the history of science top down, and browse e.g. by date. You can share what you’ve found.
