  • Mediation Analysis in Online Experiments at Booking. com: Disentangling Direct and Indirect Effects

    arxiv

    Online experimentation is at the core of Booking.com's customer-centric product development. While randomised controlled trials are a powerful tool for estimating the overall effects of product changes on business metrics, they often fall short in explaining the mechanism of change. This becomes problematic when decision-making depends on being able to distinguish between the direct effect of a treatment on some outcome variable and its indirect effect via a mediator variable. In this paper, we…

    Online experimentation is at the core of Booking.com's customer-centric product development. While randomised controlled trials are a powerful tool for estimating the overall effects of product changes on business metrics, they often fall short in explaining the mechanism of change. This becomes problematic when decision-making depends on being able to distinguish between the direct effect of a treatment on some outcome variable and its indirect effect via a mediator variable. In this paper, we demonstrate the need for mediation analyses in online experimentation, and use simulated data to show how these methods help identify and estimate direct causal effect. Failing to take into all confounders can lead to biased estimates, so we include sensitivity analyses to help gauge the robustness of estimates to missing causal factors.

  • Customizable georeferenced deduduplication system

    We have developed a new general puporse system. It's easily extensible, and strongly based on natural language methods. This way, we developed a large expert system, trained to find duplicated documents, even with a great level of noise.

  • Dynamic parsing and entity discovery for web search

    -

    We have developed a dynamic parsing system based on entity discovery for a better web search. It's been used in the main address search at www.apontador.com

  • Geofenced local discovery

    -

    Our main objective for this project is developing ways of discovering where a people is, based on his past actions and choices. This way we can predict their location without a manual checkin.

  • Real-time recommendation system

    -

    The purpose of this project was to develop a recommendation system, based on real-time methods. It's been used on several system, but's the main objective is increasing the CTR of internal advertising.

  • Traffic report

    -

    In this project we have developed a set of tools capable of mining terabytes of data finding specific patterns of congestion and commute time.
