A Cross-Language Question/Answering-System for German and English
نویسندگان
چکیده
This report describes the work done by the QA group of the Language Technology Lab at DFKI, for the 2003 edition of the Cross-Language Evaluation Forum (CLEF). We have participated in the new track “Multiple Language Question Answering (QAatCLEF)” that offers tasks to test monolingual and cross-language QA–systems. In particular we developed an open–domain bilingual QA–System for German source language queries and English target document collections. Since it was our very first participation at such kind of competition, the focus was on system implementation rather than system tuning.
