We participated in two tasks: Multi-8 two-years-on retrieval and Multi-8 results merging. For the multi-8 two-years-on retrieval work, algorithms are proposed to combine simple multilingual ranked lists into a more accurate ranked list. Empirical study shows that the approach of combining multilingual retrieval results can substantially improve the accuracies over single multilingual ranked lists. The Multi-8 results merging task is viewed as similar to the results merging task of federated search. Query-specific and language-specific models are proposed to calculate comparable document scores for a small amount of documents and estimate logistic models by using information of these documents. The logistic models are used to estimate comparable scores for all documents and thus the documents can be sorted into a final ranked list. Experimental results demonstrate the advantage of the query-specific and language-specific models against several other alternatives.
