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.
