Addressing social bias in information retrieval

Journalists and researchers alike have claimed that IR systems are socially biased, returning results to users that perpetuate gender and racial stereotypes. In this position paper, I argue that IR researchers and in particular, evaluation communities such as CLEF, can and should address such concerns. Using as a guide the Principles for Algorithmic Transparency and Accountability recently put forward by the Association for Computing Machinery, I provide examples of techniques for examining social biases in IR systems and in particular, search engines. � Springer Nature Switzerland AG 2018.
