INTRODUCTION

English translation pending.

CORE DEFINITION

A common-sense reasoning net, exemplified by projects such as ConceptNet, encodes everyday knowledge as nodes and typed relations covering causality, purpose and attributes. Its core proposition is that much of human competence rests on unstated assumptions, and that making those assumptions explicit in a traversable graph lets systems perform default reasoning and fill in missing premises. The key qualification is that such networks capture only a slice of shared knowledge, since common sense varies by culture, context and era, so any graph remains partial and defeasible rather than universally true.

SCAFFOLDING EFFECT

Reduce cognitive load

- Make Tacit Explicit: write down the assumptions everyone treats as obvious and give each one a node. - Traverse For Defaults: walk the graph to infer unstated premises before accepting a conclusion. - Flag Exceptions: mark nodes such as penguins that override a general rule like birds fly.

Anchor fast decisions

Reasoning breaks down when a needed premise is never stated, so the net supplies those premises as retrievable edges. Because relations are typed and directional, traversal can chain facts, for example reaching bird to can-fly and then hitting an exception edge for penguin. Each added edge expands the reachable inference set, which is why coverage and relation quality matter more than raw node count.
