Abstract
A benchmark evaluation dataset which reflects users' search behaviors in the real world is indispensable for evaluating the performance of information retrieval applications. A typical evaluation dataset consists of a document set, a topic set and relevance judgments. Manual preparation of an evaluation dataset needs much human cost, and human-made topics may not fully capture users' real search needs. This paper aims at automatically constructing an evaluation dataset from wisdom of the crowds in search query logs for information retrieval applications. We begin with collecting documents of clicked documents in search query logs, selecting suitable queries in terms of topics, sampling documents from the document collection for each query and estimating the multi-level relevance of document samples based on click count, normalized count and average count functions. The machine-made evaluation dataset is trained and tested by three learning to rank algorithms, including linear regression, SVMRank and FRank. We compare their performance on a testing collection MQ2007 of LETOR which is a well-known human-made benchmark dataset for learning to rank. The experimental results show that the performance tendency is similar by using machine-made and human-made evaluation datasets. That demonstrates our proposed models can construct an evaluation dataset with similar quality of human-made. ? 2012 IEEE.
