We describe our participation in Multilingual Question Answering at CLEF 2008 using German and English as our source and target languages, respectively. The system was built using UIMA (Unstructured Information Management Architechture) as underlying

We describe a question answering system that took part in the bilingual CLEFQA task (German-English) where German is the source language and English the target language.We used the BableFish online translation system to translate the German questions

STARTPAGE=9;ENDPAGE=16;TITLE=Proceedings ACL-2005 Workshop on Feature Engineering

We present the results of feature engineering and post-processing experiments conducted on a temporal expression recognition task. The former explores the use of different kinds of tagging schemes and of exploiting a list of core temporal expressions

Proceedings ACL-2005 Workshop on Computational Approaches to Semitic Languages

We applied Conditional Random Fields (CRFs) to the tasks of Amharic word segmentation and POS tagging using a small annotated corpus of 1000 words. Given the size of the data and the large number of unknown words in the test corpus (80%), an accuracy
