Agreement Contexts in Formal Concept Analysis

摘要

This paper describes a technique in which some columns of an n-ary relation are interpreted as defining a situation. For example when considering movies, critics and reviews we talk about the situation when the critic is a particular critic. We then construct a formal context called an agreement context designed to show that which is in common between the situations. We elaborate this idea in two ways: (ⅰ) by combining different types of situation; and (ⅱ) using conceptual scales to introduce intervals of agreement.
