The prime aspect of quality for search-driven web applications is to provide users with the best possible results for a given query. Thus, it is necessary to predict the relevance of results a priori. Current solutions mostly engage clicks on results for respective predictions, but research has shown that it is highly beneficial to also consider additional features of user interaction. Nowadays, such interactions are produced in steadily growing amounts by internet users. Processing these requires streaming-based approaches and incrementally updateable relevance models. We present StreamMyRelevance! (SMR)--a novel streaming-based system for ensuring quality of ranking in search engines. Our approach provides a complete pipeline from collecting interactions in real-time to processing them incrementally on the server side. We conducted a large-scale evaluation with real-world data from the hotel search domain. Results show that our system yields predictions as good as those of competing state-of-the-art systems:
- Bayesian Browsing Model (BBM),
- TellMyRelevance! (TMR),
- a click-only version of SMR, and
- a click-only version of TMR,
but by design of the underlying framework at higher efficiency, robustness and scalability.
