| Challenge: | Comparative Question Answering (cQA) is the task of providing accurate answers to questions . most question answering systems focus on answering factoid questions, but they fail at answering comparative questions in an efficient argumentative manner. |
| Approach: | They propose two new open-domain datasets for identifying and labeling comparative questions . they use a binary classification task and an unsupervised sequence labeling task . |
| Outcome: | The proposed datasets reach close-to-human results on a binary classification task with a neural model using ALBERT embeddings. |
