Text Analytics: Crowdsourcing
How would it be if hundreds of people worked for me?
This experience can be made in the 2012/13 edition seminar in the TextAnalytics series.
As a seminar project, we will create linguistic annotations using crowdsourcing. Crowdsourcing allows us to distribute simple tasks over a large number of crowdworkers that are paid for this. Funds are available for about 10 projects.
These annotations will be used in language technology software to create processing components based on machine learning. At this, the quality of the component is dependent on size and quality of the anotated dataset.
By creating and using datasets, students get to know the entire process chain of statistical natural language processing: in practice, especially the creation of datasets is a challenge.
This seminar is being held in the format of a Mini-Workshop: After an introductory lecture, individual topics are assigned. Introductory literature by topic, as well as a basic software environment and a manual for crowdsourcing is provided. Students write a paper, consisting of a literature overview and a description of their own experiment. Papers are mutually peer-reviewed. In a final workshop, the work is presented in a 20 minute presentation.
Research papers will be distributed per topic.
Each student is expected to
- write a term paper
- review other student papers
- give a 20 min. talk in class + 10 min. Q&A afterwards
Introduction Session: 16.10.2011
