Overview and results of Morpho Challenge 2010
In Morpho Challenge 2010 unsupervised and semi-supervised algorithms are sug- gested to provide morpheme analyses for words in different languages that can be used in various practical applications. Morpheme analysis is particularly use- ful in speech recognition, information re- trieval and machine translation for mor- phologically rich languages where the amount of different word forms is very large. The evaluations in Morpho Chal- lenge consist of: 1. comparisons to gram- matical morphemes, 2. information re- trieval experiments based on morphemes instead of words, and 3. machine trans- lation experiments where morpheme and word based systems are combined. The evaluation languages are: Finnish, Turk- ish, German, and English. This overview paper describes the goals, data, tasks, par- ticipants, evaluations, and obtained re- sults. The Morpho Challenge is part of the EU Network of Excellence PASCAL2 Challenge Program.
