AREDSUM: Adaptive Redundancy-Aware Iterative Sentence Ranking for Extractive Document Summarization (2021.eacl-main)
Copied to clipboard
| Challenge: | Existing studies on redundancy are focused on salience alone. |
| Approach: | They propose to combine salience and novelty to score redundancy in extractive summarization systems . they also propose to balance saliance and redundancies by scoring redundants first . |
| Outcome: | Empirical results show that AREDSUM-CTX scores salience first, then learns to balance saliency and redundancy. |

Anish Acharya, Suranjit Adhikari, Sanchit Agarwal, Vincent Auvray, Nehal Belgamwar, Arijit Biswas, Shubhra Chandra, Tagyoung Chung, Maryam Fazel-Zarandi, Raefer Gabriel, Shuyang Gao, Rahul Goel, Dilek Hakkani-Tur, Jan Jezabek, Abhay Jha, Jiun-Yu Kao, Prakash Krishnan, Peter Ku, Anuj Goyal, Chien-Wei Lin, Qing Liu, Arindam Mandal, Angeliki Metallinou, Vishal Naik, Yi Pan, Shachi Paul, Vittorio Perera, Abhishek Sethi, Minmin Shen, Nikko Strom, Eddie Wang
| Challenge: | Traditional goal-oriented dialogue systems require annotations which are hard to obtain for every new domain, limiting scalability. |
| Approach: | They propose a data-driven approach to building goal-oriented dialogue systems . they use a seed dialogue simulator to generate annotated conversations instead of collecting annotations . |
| Outcome: | The proposed system improves turn-level action signature prediction accuracy by 50% . the system is scalable, extensible and data efficient . |
Bag of Experts Architectures for Model Reuse in Conversational Language Understanding (N18-3)
Copied to clipboard
| Challenge: | Slot tagging is a key component of natural language understanding systems for personal digital assistants. |
| Approach: | They propose to use a bag of experts architecture to reuse domain data for slot tagging models. |
| Outcome: | Experiments with 10 domains show that the proposed models outperform baseline models by 5.06% and 12.16% when training with only 25% of the training data. |

| Challenge: | Existing work on meeting summarization tasks is limited to short summaries that cover all the content of a meeting. |
| Approach: | They propose a query-based multi-domain meeting summarization task that generates a single short summary of meetings based on a transcript. |
| Outcome: | The proposed task is based on 1,808 query-summary pairs over 232 meetings in multiple domains. |
GO FIGURE: A Meta Evaluation of Factuality in Summarization (2021.findings-acl)
Copied to clipboard
| Challenge: | Recent advances in text generation systems produce fluent, coherent, relevant, and factually correct text. |
| Approach: | They propose a metaevaluation framework for evaluating factuality evaluation metrics . they propose five necessary conditions to evaluate factual metrics on diagnostic factuity data . |
| Outcome: | The proposed framework provides robust evaluation that is extensible to multiple types of factual consistency and standard generation metrics, including QA metrics. |
