SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill helps researchers understand how a research problem evolves by tracing the critique and improvements across a sequence of papers, from origin to current progress.

Core Features & Use Cases

  • Recursive lineage tracing: follow 1-5 precursor papers and identify the core problem and solution shifts.
  • Forward extension: analyze post-origin papers that address or modify the lineage to capture ongoing developments.
  • Structured narrative: produce a clear, citation-rich evolution outline with concise summaries.

Quick Start

Input a target paper's URL or title and the system will perform up to five layers of tracing to generate a coherent evolution narrative.

Frequently Asked Questions about ljg-paper-river

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I trace the research lineage of an academic paper?

To trace research lineage, input a target paper's URL or title and the system recursively identifies prerequisite papers and later progress, generating a structured evolution narrative up to five layers deep.

What is recursive citation chain tracing for scholarly papers?

Recursive citation chain tracing identifies precursor papers and analyzes core problem and solution shifts across a sequence of scholarly papers, mapping the evolution of a research problem from origin to current progress.

How do I map prerequisite papers to understand a research problem's evolution?

Map prerequisite papers by inputting a target paper's title or URL; the system extracts metadata, follows up to five precursor layers, and produces a citation-rich evolution outline highlighting core questions and solutions.

Can I analyze downstream progress and modifications for a specific research problem?

Yes, you can analyze downstream progress by forward extending the lineage to capture post-origin papers that address or modify the research problem, integrating ongoing developments into the final structured narrative.

What are the limitations of recursive tracing for academic analysis?

The primary limitation of recursive tracing is the enforced depth constraint, which limits precursor and downstream analysis to a maximum of five layers to maintain an interpretable and structured lineage narrative.

Does ljg-paper-river support academic analysis across different disciplines?

Yes, ljg-paper-river supports academic analysis across all scholarly disciplines, tracing the critique and improvements of research problems by extracting titles, authors, years, and core solutions from any field.
