What about unicorns? Concept, yes, but extension, no.
I actually know Lattice Theory out the wazoo, but I still fail to understand what this article is about. Does anyone care to shed any light on the subject? In particular, what is the purpose of this subject? How is it useful? Why is it interesting enough that people have written books and articles on it? It seems vaguely interesting but the current article doesn't really communicate the usefulness or purpose of this subject. Cazort 21:40, 23 October 2007 (UTC)

The first sentence in Recovering ... reads: The Hasse diagram of the concept lattice ... encodes enough information to recover the original context from which it was formed.
Looking at the graphics of the Example (O = {1,2,3,4,5,6,7,8,9,10}, A = {composite,even,odd,prime,square}) and following the description in Recovering I wonder how to recover for example every single of the three numbers 3, 5, 7 from the Hasse diagram since the diagram with O' = {1,2,3,4,6,8,9,10}, A' = A is the same but without the objects 5 and 7 (or the one "ignoring" 6 and 8: O= {1,2,3,4,9,10}, A = A). —Preceding unsigned comment added by 87.184.91.223 ( talk) 13:06, 5 August 2008 (UTC)
I would add an extra point to the comment above: it doesn't make much sense to instantiate the example, before stating the formal definitions. The comment above is from 2008, almost 4 years old. In this case I may change the order, and improve both sections if there is no further comments within 2 months Pedro 17:32, 24 February 2012 (UTC) — Preceding unsigned comment added by Pcgomes ( talk • contribs)
Today there was some back-and-forth between me and Jwollbold regarding the start of the article. See this diff for Jwollbold's suggested replacement for the start. My take on it is that the new text is far too formal and abstract, giving readers no idea what FCA is good for or why they should care about it, and that we should start more gently and non-technically as the previous introduction did. But I welcome more discussion here. — David Eppstein ( talk) 18:31, 22 April 2012 (UTC)
We have considerably revised the German version of this article about a year ago. "We", this is a group, most of us mathematicians at "Ernst Schröder Center for Conceptual Knowledge Processing". Among us, Bernhard Ganter one of the authors of Formal Concept Analysis. Foundations and Applications online-description, Peter Burmeister and Karl Erich Wolff', retired math professors who also were involved in the development of FCA. (see Overview and history and References)
One of our main goals in revising the article was, to write the article in a way, not only comprehensible to mathematicians, as Wikipedia is an encyclopedia for everyone. Not to mention, that Rudolf Wille who can be regarded to be the father of FCA always tried hard to get math out of the ivory tower.
We would like to blend in some of our ideas into this English article. I have tried to translate the introduction of the German article to English: User:MRewald/FBA. We are interested in a cooperation to improve the article.
In the German article we also have replaced the example section by an example, we believe to be more related to practical use. This would be one of the next sections I'd be going to translate. We also have added a list of publications which deal with the practical application of FCA.
I just uploaded a figure in English language with the line chart of the example we used in the German article. Example (de)
Looking forward to productive cooperation -- MRewald ( talk) 20:32, 23 November 2017 (UTC)
I have started revising the article, based on the work of the German editing group (see the post of MRewald above. A revison seems necessary because the article contains many inaccuracies. Moreover, some parts of it are not really about the topic.

I have removed the "disambiguation needed" tags in the data set on "bodies of water". Reason: this data is a citation from a semantic field study, and should therefore not be altered. The author of that study did not disambiguate, because that is left to the semantic field. -- Bernhard Ganter ( talk) 16:46, 2 February 2018 (UTC)
In the section "Extensions of the theory: Triadic concept analysis", Klaus Biedermann should be cited, not only Rudolf Wille. Biedermann did the formalization of the "triadic Galois connection" and other triadic fundamentals. Wille invented the derived trilattice structure and diagram. 70.112.90.106 ( talk) 11:46, 30 October 2018 (UTC)
