Title: Using human computation in a Web-based game to create resources for NLP.
The goal of the ANAWIKI project at Essex University is to experiment with Web collaboration and human computation to create large-scale linguistically annotated corpora.
The motivation for this is the observation that a group of individuals can contribute to a collective solution, which has a better performance and is more robust than an individual's solution as demonstrated in simulations of collective behaviours in self-organizing systems.
Wikipedia is perhaps the best example of collaborative resource creation, but it is not an isolated case. The gaming approach to data collection, termed games with a purpose, has received increased attention since the success of von Ahn's ESP game.
We will present a short history of related work, as well as a demonstration and initial results of Phrase Detectives, a game designed to collect judgments about anaphoric annotations.
