Título: Benchmarking and Evaluation Campaigns: the good, the bad, and the metrics

Conferenciante: Julio Gonzalo, UNED.

Competitive evaluation exercises have become mainstream in the Natural Language Processing and Information Retrieval research communities. Based on experiences at WePS (the Web People Search evaluation initiative) and CLEF (the Cross-Language Evaluation Forum), we will discuss the benefits and risks of focusing research around evaluation campaigns, and highlight some unresolved dilemmas. The presentation will make a special emphasis on metric design as a key feature which is often overlooked in mainstream experimental designs, and we will conclude with the presentation of a new metric, the Unanimous Improvement Ratio (UIR), which contributes to the analysis of experimental results when more than one metric is involved in the evaluation - as it is the case of Precision and Recall in many evaluation settings).
