Network Mapper
Create term maps and co-authorship networks from an Excel template without sending your data to a server.The file is processed only in this browser. Call For Science does not store it.This note describes the general procedure applied to every Call For Science map.
How this figure is constructed
Each Excel row represents one document. In a term map, nodes are terms; in co-authorship, nodes are authors. Node size represents the number of documents in which each node occurs.
Link width represents raw co-occurrence or co-authorship. Distance is derived from normalized association strength: co-occurrence divided by the product of both node occurrence counts. Curved links are a rendering choice only and do not change node coordinates.
Clusters are detected with a deterministic weighted label-propagation procedure; very small isolated groups are consolidated into the connected community with which they share the greatest association strength. The layout starts from a deterministic community grouping and is then optimized using normalized associations. Clusters are numbered from largest to smallest. Each color is a categorical community identifier: it does not represent importance or quality. Each proposed name uses the most frequent term or author; a local glossary suggests its equivalent and the user can edit both versions.
