Learning to Extract Local Events from the Web
John Foley, Michael Bendersky, Vanja Josifovski · 2015
The goal of this work is extraction and retrieval of local events from web pages. Examples of local events include small venue concerts, theater performances, garage sales, movie screenings, etc. We collect these events in the form of retrievable calendar entries that include structured information about event name, date, time and location. Between existing information extraction techniques and the availability of information on social media and semantic web technologies, there are numerous ways to collect commercial, high-profile events. However, most extraction techniques require domain-level supervision, which is not attainable at web scale. Similarly, while the adoption of the semantic web has grown, there will always be organizations without the resources or the expertise to add machine-readable annotations to their pages. Therefore, our approach bootstraps these explicit annotations to massively scale up local event extraction.
