Mining for Unknown Unknowns
Unknown unknowns are future relevant contingencies that lack an ex ante
description. While there are numerous retrospective accounts showing that
significant gains or losses might have been achieved or avoided had such
contingencies been previously uncovered, getting hold of unknown unknowns still
remains elusive, both in practice and conceptually. Using Formal Concept
Analysis (FCA) - a subfield of lattice theory which is increasingly applied for
mining and organizing data - this paper introduces a simple framework to
systematically think out of the box and direct the search for unknown unknowns.Comment: In Proceedings TARK 2023, arXiv:2307.0400
Simulating Language Dynamics by Means of Concept Reasoning
A problem in the phenomenological reconstruction of Complex
Systems (CS) is the extraction of the knowledge that elements playing
in CS use during its evolution. This problem is important because
such a knowledge would allow the researcher to understand the global
behavior of the system [1,2]. In this paper an approach to partially solve
this problem by means of Formal Concept Analysis (FCA) is described in
a particular case, namely Language Dynamics. The main idea lies in the
fact that global knowledge in CS is naturally built by local interactions
among agents, and FCA could be useful to represent their own knowledge.
In this way it is possible to represent the effect of interactions
on individual knowledge as well as the dynamics of global knowledge.
Experiments in order to show this approach are given using WordNet.Ministerio de Ciencia e Innovación TIN2009-09492Junta de Andalucía TIC-606
