Timeline Summarization

Description from the archive archive 2025-07-28.

Benchmarks archive 2025-07-28

1 leaderboard table shown for this task, 1 with rows (a “benchmark” on this site is a table with at least one row, as on /sota), ordered by row count. “Best model” is the first row in the archive's own order at snapshot; nothing is re-ranked here and metric direction is not recorded in the archive. PwC's Trend sparklines are not in the archive, so that column is omitted.

Syntology column: samples harvested from the paper's repositories and executed on synthesized fixtures; “ran” is not a correctness claim and does not order the table. A dash means no Syntology record for that paper, not a recorded non-run. Read from the graph 2026-09-24.

Libraries

Not in the archive: the export carries no per-task library table, so there is nothing to show at snapshot 2025-07-28.

8 shown of 8 papers with code (25 tagged with this task in all), ordered by repositories listed in the archive, not by stars (the archive holds no stars, so PwC's “Social” and “Latest” sorts cannot be reproduced). Papers without a page here are shown as plain text.

• Unfolding the Headline: Iterative Self-Questioning for News Retrieval and Timeline Summarization
  1 Jan 2025 1 repository listed
  In the fast-changing realm of information, the capacity to construct coherent timelines from extensive event-related content has become increasingly significant and challenging.
• Just What You Desire: Constrained Timeline Summarization with Self-Reflection for Enhanced Relevance
  23 Dec 2024 1 repository listed
  We propose an approach that employs a large language model (LLM) to summarize news articles according to a specified constraint and cluster them to identify key events to include in a constrained timeline.
• DTELS: Towards Dynamic Granularity of Timeline Summarization
  14 Nov 2024 1 repository listed
  The rapid proliferation of online news has posed significant challenges in tracking the continuous development of news topics.
• Follow the Timeline! Generating Abstractive and Extractive Timeline Summary in Chronological Order
  2 Jan 2023 1 repository listed
  Nowadays, time-stamped web documents related to a general news query floods spread throughout the Internet, and timeline summarization targets concisely summarizing the evolution trajectory of events along the timeline.
• Timeline Summarization based on Event Graph Compression via Time-Aware Optimal Transport
  1 Nov 2021 1 repository listed
  Timeline Summarization identifies major events from a news collection and describes them following temporal order, with key dates tagged.
• Examining the State-of-the-Art in News Timeline Summarization
  20 May 2020 1 repository listed Syntology ran 5 of 8 samples · 3 unverified
  Previous work on automatic news timeline summarization (TLS) leaves an unclear picture about how this task can generally be approached and how well it is currently solved.
• Learning towards Abstractive Timeline Summarization
  11 Aug 2019 1 repository listed
  Timeline summarization targets at concisely summarizing the evolution trajectory along the timeline and existing timeline summarization approaches are all based on extractive methods.
• A Temporally Sensitive Submodularity Framework for Timeline Summarization
  18 Oct 2018 1 repository listed Syntology ran 0 of 7 samples · 7 unverified
  Timeline summarization (TLS) creates an overview of long-running events via dated daily summaries for the most important dates.

Syntology lines on 2 of the papers shown; no Syntology record for the others (a paper without an arXiv id cannot be joined to the graph, and absence from the graph layer is not a recorded non-run). “Ran” means the sample executed on a synthesized fixture, not that the paper's result was reproduced.
