Abstract
The Lydia project seeks to build a relational model of people, places, and things through natural language processing of news sources and the statistical analysis of entity frequencies and co-locations. The analysis is quite different from Google News. Temporal and spatial distribution of the entities in the news are tracked: who is being talked about, by whom, when, and where? Visit this website (textmap.com) to see an analysis of recent news obtained from over 500 daily online news sources.

In this talk, Dr. Skiena will demonstrate Lydia and describe its architecture. He will focus on topics of current research, including sentiment analysis, identifying synonymous entity names, and the comparative analysis of blogs and formal news sources.
