Conversion Models: Building Learning to Rank Training Data - Doug Turnbull, OpenSource Connections

When using user signals to improve relevance, what should you use? Clicks are more frequent, but really only correspond to a search result looking attractive. A conversion is a powerful signal of true relevance but occurs less frequently. Can we combine shallow "this looks interesting" click events along with strong, but rare conversion signals in a robust fashion to generate learning to rank training data? Learn about click models, an industry-proven way of measuring search result attractiveness from clicks, and a systematic way of incorporating conversion data into click models. Whether your industry is conversion heavy (like e-commerce), or lacking in any clear conversion signal (like publishing) you'll take away from this talk a system for turning any search analytics into robust judgments and training data. Because, after all, there is no AI-based Search without good training data!
