| Challenge: | 6.3k arguments were collected from contributors of various levels, and are released as part of this work. |
| Approach: | They propose to use a language model to annotate arguments for argument ranking and argument-pair classification. |
| Outcome: | The proposed methods outperform state-of-the-art methods in the argument ranking task and argument-pair classification task. |
From Arguments to Key Points: Towards Automatic Argument Summarization (2020.acl-main)
Copied to clipboard
| Challenge: | Recent work on topic-related argument mining has made it difficult to read and digest large amounts of information. |
| Approach: | They propose to represent arguments as a small set of talking points, termed key points, each scored according to its salience. |
| Outcome: | The proposed method can predict key points in advance, and it performs well. |
Quantitative argument summarization and beyond: Cross-domain key point analysis (2020.emnlp-main)
Copied to clipboard
| Challenge: | Recent work on multi-document summarization lacks quantitative aspect of summarizing views, arguments or opinions . authors develop method for automatic extraction of key points, which is comparable to a human expert . |
| Approach: | They propose to map arguments to a small set of expert-generated key points . they demonstrate that the applicability of key point analysis goes well beyond argumentation data . |
| Outcome: | The proposed method outperforms arguments in municipal surveys and user reviews . it is shown that the extraction of key points is comparable to a human expert . |

| Challenge: | Argument Invention is a task that is often referred to as a natural way of inventing arguments, but has not been formalized in the context of NLP. |
| Approach: | They propose to define a taxonomy of recurring arguments and to automatically identify which of them are relevant to the topic. |
| Outcome: | The proposed taxonomy is coherent, covers the relevant topics and coincides with what debaters actually argue in their speeches, and facilitates automatic argument invention for new topics. |

Shai Gretz, Assaf Toledo, Roni Friedman, Dan Lahav, Rose Weeks, Naor Bar-Zeev, João Sedoc, Pooja Sangha, Yoav Katz, Noam Slonim
| Challenge: | As COVID-19 vaccines were rolled out, they were met with widespread hesitancy. |
| Approach: | They propose a new framework for intent discovery that leverages existing intent classifiers to provide a real-world conversational dataset of conversations conducted by actual users with VIRA. |
| Outcome: | The proposed framework enables users to find out what they are doing and why they are hesitant. |
Out of the Echo Chamber: Detecting Countering Debate Speeches (2020.acl-main)
Copied to clipboard
| Challenge: | Existing algorithms to detect articles that counter the arguments in debate speeches are unsuccessful, suggesting room for further research. |
| Approach: | They propose a task to detect articles that counter the arguments made in debate speeches by annotating them from a dataset of 3,685 such speeches. |
| Outcome: | The proposed algorithm can detect articles that counter the arguments made in debate speeches, and some are successful, but none are human-like. |
