Basic usage
Connected Papers is extremely simple to operate. Enter a paper to generate a connected map.
Generate paper correlation map
Steps: 1. Visit connectedpapers.com 2. Enter the paper title or DOI in the search box For example: "BERT: Pre-training of Deep Bidirectional Transformers" 3. Click on the target paper 4. Click "Build a graph" 5. Wait about 30 seconds for the graph to be generated Interpretation of the chart: - Node size: number of references (the larger, the more important) - Node color: publication year (the darker the color, the newer it is) - Thickness of the connection: similarity (the thicker, the more relevant) - Central node: the paper of your choice
Generate a correlation map centered on the target paper,
You can intuitively see which papers are most relevant to it,
What are the important tasks in the field?
The paper with the largest node is usually the foundational work in the field and deserves to be read first.
Distinguish between pioneer research and spin-off research
Connected Papers divides relevant papers into two categories: Prior Works: - Publish before the target paper - is the basis for the target paper - Help understand research background Derivative Works: - Publish after the target paper - Work based on the target paper - Help keep up to date with the latest developments You can switch between these two types of papers in the right panel of the map.
By precursor/derivative classification,
Quickly understand the historical background and latest developments of research,
Build a complete timeline perspective.
See Prior Works first for background, then Derivative Works for the latest developments.
Tips for efficient use
Master these tips to get the most from Connected Papers in your literature review.
Start exploring with a review paper
Best practices: 1. First find the latest review paper (Survey) in the field 2. Use review papers to generate maps 3. Review papers usually cite all important work in the field 4. The largest node in the graph is the most important paper Tips for searching for review papers: Search on Google Scholar: "survey [your topic] 2024" or "review [your topic] 2024"
Starting from the review paper,
You can quickly find all important jobs in your field,
More efficient than starting from a single research paper.
There are 5 free map generations per month, and the paid version is unlimited.
