| Challenge: | Manual evaluation methods are perceived as insufficient due to the high cost of the Pyramid method and the required expertise. |
| Approach: | They propose a crowdsourced method that compares system summaries to references and uses crowdsourced scripts to analyze the results. |
| Outcome: | The proposed method shows higher correlation relative to the original Pyramid method. |
Extending Multi-Document Summarization Evaluation to the Interactive Setting (2021.naacl-main)
Copied to clipboard
| Challenge: | Existing approaches to interactive summarization are incomparable and divergent . a key gap in the development and adoption of interactive summaries is the lack of evaluation methodologies and benchmarks for meaningful comparison of systems. |
| Approach: | They propose an end-to-end evaluation framework for interactive summarization based on expansion-based interaction . framework includes procedure of collecting real user sessions, evaluation measures relying on summarizing standards, but adapted to reflect interaction. |
| Outcome: | The proposed evaluation framework is based on evaluations of baseline implementations and is available publicly as a benchmark. |
Evaluating Multiple System Summary Lengths: A Case Study (D18-1)
Copied to clipboard
| Challenge: | Practical summarization systems are expected to produce summaries of varying lengths, per user needs. |
| Approach: | They propose to use ROUGE metric to evaluate system summaries of multiple lengths. |
| Outcome: | The evaluation protocol in question is competitive, the authors show . they found that the evaluation protocol is competitive with existing benchmarks. |
iFacetSum: Coreference-based Interactive Faceted Summarization for Multi-Document Exploration (2021.emnlp-demo)

Eran Hirsch, Alon Eirew, Ori Shapira, Avi Caciularu, Arie Cattan, Ori Ernst, Ramakanth Pasunuru, Hadar Ronen, Mohit Bansal, Ido Dagan
| Challenge: | iFS provides a faceted navigation scheme that provides abstractive summaries for the user’s selections. |
| Approach: | They propose a web application that integrates interactive summarization and faceted search to provide a faceted navigation scheme that yields abstractive summaries for the user's selections. |
| Outcome: | The proposed system provides a comprehensive overview as well as particular details regard-ing subtopics of interest. |
