------------------ 2017 RecSys Challenge ------------------
-----------------------------------------------------------------------
Dear Colleague,

We are pleased to announce the 2017 RecSys Challenge in conjunction with ACM RecSys 2017.

The RecSys Challenge 2017 is organized by XING, Politecnico Milano and Free University of Bozen-Bolzano. XING is a social network for business. People use XING, for example, to find a job and recruiters use XING to find the right candidate for a job. At the moment, XING has more than 18 million users and typically around 1 million active job postings on the platform.

This year's edition of the RecSys Challenge aims to better connect job seekers and recruiters via job recommendations. The challenge focuses on a cold-start scenario: given a new job posting, the goal is to identify those users that (a) may be interested in receiving the job posting as a push recommendation and (b) that are also appropriate candidates for the given job.

The RecSys Challenge will consist of two phases: (1) offline evaluation and (2) online evaluation.
A detailed description of the challenge can be found on the website of the RecSys Challenge 2017 (recsyschallenge.com<http://recsyschallenge.com/>). Accepted contributions will be presented during the RecSys Challenge 2017 Workshop.

We encourage all, industry and academia members, to participate in the challenge and submit solutions. Cash prizes are set and publication of selected and winning solutions is guaranteed.
