Dynamic Test Collections: Measuring Search Effectiveness on the Live Web

Abstract
Existing methods for measuring the quality of search algorithms use a static collection of documents. A set of queries and a mapping from the queries to the relevant documents allow the experimenter to see how well different search engines or engine configurations retrieve the correct answers. This methodology assumes that the document set and thus the set of relevant documents are unchanging. In this paper, we abandon the static collection requirement. We begin with a recent TEXT REtrieval Conference (TREC) collection created from a web crawl, and analyze how the documents in that collection have changed over time. We determine how the decayed collection to measure a live web search system. We employ novel measures of search effectiveness that are robust despite incomplete relevance information. Lastly, we propose a methodology of "collection maintenance" which supports measuring search effectiveness both for a single system and between systems run at different points in time.
