This year Dublin City University participated in the CLEF 2005 Mulit-8 Two-Years-On multilingual merging task. The objective of our experiments was to test a range of standard techniques for merging ranked lists of retrieved documents to see if consistent trends emerge for lists generated using different information retrieval systems. Our results show that the success of merging techniques can be dependent on the retrieval system used, and in consequence the best merging techniques to adopt cannot be recommended independent of knowing the retrieval system to be used.
