Sample text

All topic sets were created by native speakers. One of the decisions taken early on in the organization of the CLEF ad hoc tracks was that for each task the same set of topics, rendered in different languages, would be used to query the different collections. There were a number of reasons for this: it makes it easier to compare results over different target languages, it means that there is a single master set that is rendered in all query languages, and a single set of relevance assessments for each language is sufficient for all tasks.

All groups participating in the Indian languages sub-task also had to submit at least one run in Hindi (mandatory) plus runs in other Indian languages (optional). CLEF 2007: Ad Hoc Track Overview 23 Table 5. 61% We were disappointed to only receive runs from one participant for the X → BG, CS, or HU tasks. Furthermore, the results were quite poor; as this group normally achieves very good performance, we suspect that these runs were probably corrupted in some way. For this reason, we decided to disregard them as being of little significance.

Acknowledgements We should like to acknowledge the enormous contribution of the groups responsible for topic creation and relevance assessment. In particular, we thank the group responsible for the work on Bulgarian led by Kiril Simov and Petya Osenova, the group responsible for Czech led by Pavel Pecina7 , and the group responsible for Hungarian led by Tam´ as V´aradi and Gergely Botty´an. These groups worked very hard under great pressure in order to complete the heavy load of relevance assessments in time.
