Welcome to the second edition of the 3C Citation Context Classification shared task based on Influence. This year, we organise this competition as part of the [Second Workshop on Scholarly Document Processing (SDP) @ NAACL 2021](https://sdproc.org/2021/index.html) . The subtask B of the 3C Shared task aims at classifying citations based on their influence. This binary classification problem has the following classes: INCIDENTAL INFLUENTIAL More details about the shared task can be viewed [here](https://sdproc.org/2021/sharedtasks.html#3c) . Task participants are required to : Develop methods addressing the task and submit the results via Kaggle Document and submit their method as a short paper as specified on the [SDP 2021](https://sdproc.org/2021/cfp.html#submission) website Provide source code for each method The paper and code should be submitted via [Softconf](https://www.softconf.com/naacl2021/sdp2021/user/scmd.cgi?scmd=submitNew) . More details regarding the submission will be made available on the [SDP](https://sdproc.org/2021/sharedtasks.html#3c) website.
