A major determinant of the quality of software systems is the quality of their requirements,
which should be both understandable and precise. Most requirements are written in natural …

During the last three decades, formal concept analysis (FCA) became a well‐known
formalism in data analysis and knowledge discovery because of its usefulness in important …

To maintain and understand large applications, it is important to know their architecture. The
first problem is that unlike classes and packages, architecture is not explicitly represented in …

When people or computers need to make a decision, typically multiple conflicting criteria
need to be evaluated; for example, when we buy a car, we need to consider safety, cost and …

Incomplete contexts are a kind of formal contexts in which the relationship between some
objects and some attributes is unavailable or lost. Knowledge discovery in incomplete …

During software evolution, programmers devote most of their effort to the understanding of
the structure and behavior of the system. For Object-Oriented code, this might be particularly …

Abstract We show how Formal Concept Analysis (FCA) can be applied to Collaborative
Recommenders. FCA is a mathematical method for analysing binary relations. Here we …

This paper is a tutorial on Formal Concept Analysis (FCA) and its applications. FCA is an
applied branch of Lattice Theory, a mathematical discipline which enables formalisation of …

In this chapter, we introduce Formal Concept Analysis (FCA) and some of its extensions.
FCA is a formalism based on lattice theory aimed at data analysis and knowledge …

The strategic importance of monitoring technological changes is highlighted given the ever
faster pace and increasing complexity of technological innovation. In this respect, patent …
