Recently, web collaboration (also known as crowd sourcing) has started to emerge as a viable alternative for building the large resources that are needed to build and evaluate NLP systems.
In this spirit, the Anawiki project (http://anawiki.essex.ac.uk/)  aimed at experimenting with Web collaboration and human computation as a solution to the problem of creating large-scale linguistically annotated corpora. So far, the main initiative of the project has been Phrase Detectives (PD) , a game designed to collect judgments about anaphoric annotations. To our knowledge, Phrase Detectives was the first attempt to exploit the effort of Web volunteers to annotate corpora (subsequent efforts include  and ).
- Relative Clause
- Dependency Tree
- Language Resource
- Annotate Corpus
- Dependency Parser
These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
