In this work, we describe our system submission to the SemEval 2021 Task 11: NLP Contribution Graph Challenge.We attempt all the three sub-tasks in the challenge and report our results.Subtask 1 aims to identify the contributing sentences in a given publication.Subtask 2 follows from Subtask 1 to extract the scientific term and predicate phrases from the identified contributing sentences.The final Subtask 3 entails extracting triples (subject, predicate, object) from the phrases and categorizing them under one or more defined information units.With the NLPContributionGraph Shared Task, the organizers formalized the building of a scholarly contributions-focused graph over NLP scholarly articles as an automated task.Our approaches include a BERT-based classification model for identifying the contributing sentences in a research publication, a rule-based dependency parsing for phrase extraction, followed by a CNN-based model for information units classification and a set of rules for triples extraction.The quantitative results show that we obtain the 5 th , 5 th , and 7 th rank respectively in three evaluation phases.We make our codes available at https://github.com/HardikArora17/
