QA Extension for Xtrieval: Contribution to the QAst track

Jens Kürsten, Holger Kundisch, Maximilian Eibl
2008 Conference and Labs of the Evaluation Forum  
The passage retrieval was done with the Xtrieval framework and its Apache Lucene implementation. For the classification of the question hand-crafted patterns were implemented.  ...  We submitted 4 experiments in total, two for each subtask t1 and t4. These subtasks employed manual speech transcription collections.  ...  Introduction This article describes the design, architecture and evaluation of a prototype extension of the Xtrieval framework [2] .  ...

Chemnitz at the CHiC Evaluation Lab 2012: Creating an Xtrieval Module for Semantic Enrichment

Jens Kürsten, Thomas Wilhelm, Daniel Richter, Maximilian Eibl
2012 Conference and Labs of the Evaluation Forum  
The evaluation of the experiments demonstrate that semantic enrichment does not improve retrieval effectiveness in comparison to straightforward baseline experiments.  ...  In this article we describe a total number of 96 experiments that have been submitted as contributions to the three subtasks of the Cultural Heritage in CLEF pilot evaluation lab.  ...  Acknowledgements This work was partly accomplished within the research project ValidAX (, funded by the German Federal Ministry of Education and Research under the grant reference  ...

A Two-step Approach to Video Retrieval based on ASR transcriptions

Ken Schmidt, Thomas Korner, Stephan Heinich, Thomas Wilhelm
2011 MediaEval Benchmarking Initiative for Multimedia Evaluation  
In this paper, we describe our experiments for the Rich Speech Retrieval Task at the MediaEval Benchmark Initiative 2011. We start with a brief overview on the used framework and its structure.  ...  Our experiments indicate that a two-step retrieval approach and applying a spell checker can improve the quality of retrieval results in the given scenario.  ...  ACKNOWLEDGMENTS This publication was prepared as a part of the research initiative sachsMedia (, which is funded by the German Federal Ministry of Education and Research under the  ...
