Humans are very good at inferring the location of events described in text, even when no places are mentioned by name. Can computers do something similar? We demonstrate a solution, using a combination of natural language processing and graph techniques applied to a corpus of online news stories.

Effective news monitoring, for competitive intelligence and other purposes, often requires an understanding of the location at which the events mentioned in an article occur. This information is sometimes not given explicitly in the text, but can be inferred using a combination of natural language processing and graph techniques. This talk describes a Neo4j-based system for performing this task. We also discuss some lessons learned along the way, and a graph-based approach to enhancing the traditional process of named entity recognition.
