Unsupervised Segmentation of Words into Morphemes Challenge
Challenge: 1 September 2005 - 12 April 2006
The objective of the Challenge is to design a statistical machine learning algorithm that segments words into the smallest meaning-bearing units of language, morphemes. Ideally, these are basic vocabulary units suitable for different tasks, such as text understanding, machine translation, information retrieval, and statistical language modeling.
The scientific goals are:
- To learn of the phenomena underlying word construction in natural languages
- To discover approaches suitable for a wide range of languages
- To advance machine learning methodology
The results will be presented in a workshop arranged in connection with other PASCAL challenges on machine learning. Please read the rules and see the schedule. The datasets are available for download. Instructions on how to submit your camera-ready documents are given on the Workshop page. We are looking forward to an interesting competition!
