Segment-level Tree Search for Long Meeting Document Summarization

arXiv:2606.08445v1 Announce Type: cross Abstract: Meeting documents are challenging to summarize due to their length and complex conversational structure. Existing approaches typically adopt multi-stage pipelines that extract information prior to summarization; however, these approaches often suffer from cumulative error propagation without intermediate validation, a limitation further amplified by short and low-quality reference summaries. We propose segment-level summarization via Monte Carlo Tree Search (S3), a training-free framework that constructs a final summary by composing segment-lev

Why this matters
Why now

The proliferation of longer and more complex digital communications, particularly in professional environments, necessitates advanced summarization techniques to manage information overload efficiently.

Why it’s important

Improved summarization capabilities directly enhance knowledge workers' productivity and decision-making by distilling critical information from extensive documents, especially in demanding meeting contexts.

What changes

This development proposes a shift from error-prone multi-stage summarization pipelines to more robust, segment-level methods, potentially leading to more accurate and reliable AI-generated summaries.

Winners
  • · AI software developers
  • · Businesses with extensive meeting documentation
  • · Knowledge workers
  • · Productivity software providers
Losers
  • · Manual summarization services
  • · Legacy summarization software utilizing multi-stage pipelines
Second-order effects
Direct

More accurate and reliable AI-powered summarization tools become widely available for very long documents.

Second

Reduced time spent by professionals on reviewing and synthesizing information from long meetings, accelerating decision cycles.

Third

Enhanced AI systems begin to extract and connect insights across numerous summarized documents, leading to emergent knowledge discovery and improved organizational intelligence.
