Multi Perspective Scientific Document Summarization With Graph Attention Networks (GATS)
Abbas Akkasi
Proceedings of the Third Workshop on Scholarly Document Processing

It is well recognized that creating summaries of scientific texts can be difficult. For each given document, the majority of summarizing research believes there is only one best gold summary. Having just one gold summary limits our capacity to assess the effectiveness of summarizing algorithms because creating summaries is an art. Likewise, because it takes subject-matter experts a lot of time to read and comprehend lengthy scientific publications, annotating several gold summaries for scientific documents can be very expensive. The shared task known as the Multi perspective Scientific Document Summarization (Mup) is an exploration of various methods to produce multi perspective scientific summaries. Utilizing Graph Attention Networks (GATs), we take an extractive text summarization approach to the issue as a kind of sentence ranking task. Although the results produced by the suggested model are not particularly impressive, comparing them to the state-of-the-arts demonstrates the model’s potential for improvement.

TakeLab at SemEval-2018 Task 7: Combining Sparse and Dense Features for Relation Classification in Scientific Texts

Proceedings of the 12th International Workshop on Semantic Evaluation

We describe two systems for semantic relation classification with which we participated in the SemEval 2018 Task 7, subtask 1 on semantic relation classification: an SVM model and a CNN model. Both models combine dense pretrained word2vec features and hancrafted sparse features. For training the models, we combine the two datasets provided for the subtasks in order to balance the under-represented classes. The SVM model performed better than CNN, achieving a F1-macro score of 69.98% on subtask 1.1 and 75.69% on subtask 1.2. The system ranked 7th on among 28 submissions on subtask 1.1 and 7th among 20 submissions on subtask 1.2.
