This is my working code for CIKM Cup 2016 (https://competitions.codalab.org/competitions/11171#learn_the_details-overview): Cross-Device Entity Linking Challenge. You can find our report here: https://arxiv.org/abs/1610.03928
Cross-Device User Matching Based on Massive Browse Logs: The Runner-Up Solution for the 2016 CIKM Cup.
Usually during a competition we will explore quite a lot of ideas, so at the last day we make the original code kind of a mess. I didn't have time to streamline the project yet. However, there are some readers asking about the source code, that's why I upload the original code first. I will refactor the code when I get more free time. Thanks!
