This repository is intended to demonstrate how the first stages of an overlay journal might be implemented for the Web Science Initiative. In the early stages we will simply collect (or link to) relevant Web Science articles and papers, and then we will enable public review and commentary features.

START, the world's first Web-based question answering system, has been on-line and continuously operating since December, 1993. It has been developed by Boris Katz and his associates of the InfoLab Group at the MIT Computer Science and Artificial Intelligence Laboratory. Unlike information retrieval systems (e.g., search engines), START aims to supply users with "just the right information," instead of merely providing a list of hits. Currently, the system can answer millions of English questions about places (e.g., cities, countries, lakes, coordinates, weather, maps, demographics, political and economic systems), movies (e.g., titles, actors, directors), people (e.g., birth dates, biographies), dictionary definitions, and much, much more.

The Lecture Browser is a web interface to video recordings of lectures and seminars that have been indexed using automatic speech recognition technology. You can search for topics, much like a regular web search engine. If any results look relevant, you can play the video starting at the relevant point and see the synchronized transcript.

AnalogySpace is a way of representing a knowledge base of common sense in a multidimensional vector space. It uses dimensionality reduction to automatically discover large-scale patterns in the data collected by the common-sense knowledge resource ConceptNet.
