INTRODUCTION

English translation pending.

CORE DEFINITION

A family of methods from information science, including co-word analysis and market basket analysis, in which elements such as words, tags, or products are counted when they appear in the same context. The core proposition is that repeated co-occurrence signals semantic or functional association, so the network of co-occurrences reveals thematic clusters and hub nodes. The key qualification is that co-occurrence is not causation and is sensitive to baseline frequency.

SCAFFOLDING EFFECT

Reduce cognitive load

- Unit selection: decide which elements, such as words or products, the analysis will connect. - Threshold setting: filter weak associations so the network stays readable. - Structure reading: use clustering and centrality to find communities and hubs.

Anchor fast decisions

Elements that belong to the same topic or serve the same function tend to appear in the same documents or transactions. Counting those co-appearances across many contexts converts a large collection of unstructured records into a graph, where the density of links reflects association strength. Graph algorithms then expose groups and connectors that are invisible in the raw data.

Although you need to use technology (the internet) for work, you should, like Thoreau at Walden Pond, artificially cut off those immediate, fragmented connections (such as social media and instant messaging), retaining only high-bandwidth, asynchronous input and output.
