  abstract = {Among many other knowledge representations formalisms, Ontologies
and Formal Concept Analysis (FCA) aim at modeling 'concepts'. We
discuss how these two formalisms may complement another from an
application point of view. In particular, we will see how FCA can
be used to support Ontology Engineering, and how ontologies can be
exploited in FCA applications. The interplay of FCA and ontologies
is studied along the life cycle of an ontology:
 (i) FCA can support the building of the ontology as a
 learning technique.
 (ii) The established ontology can be analyzed and navigated by
 using techniques of FCA.
 (iii) Last but not least, the ontology may be used to improve an FCA
 application.},

@techreport{hotho03textclustering,
  abstract = {Text document clustering plays an important role in providing intuitive
navigation and browsing mechanisms by organizing large amounts of information
into a small number of meaningful clusters. Standard partitional or agglomerative
clustering methods efficiently compute results to this end.
However, the bag of words representation used for these clustering methods is often
unsatisfactory as it ignores relationships between important terms that do not
co-occur literally. Also, it is mostly left to the user to find out why a particular partitioning
has been achieved, because it is only specified extensionally. In order to
deal with the two problems, we integrate background knowledge into the process of
clustering text documents.
First, we preprocess the texts, enriching their representations by background knowledge
provided in a core ontology — in our application Wordnet. Then, we cluster
the documents by a partitional algorithm. Our experimental evaluation on Reuters
newsfeeds compares clustering results with pre-categorizations of news. In the experiments,
improvements of results by background knowledge compared to the baseline
can be shown for many interesting tasks.
Second, the clustering partitions the large number of documents to a relatively small
number of clusters, which may then be analyzed by conceptual clustering. In our approach,
we applied Formal Concept Analysis. Conceptual clustering techniques are
known to be too slow for directly clustering several hundreds of documents, but they
give an intensional account of cluster results. They allow for a concise description
of commonalities and distinctions of different clusters. With background knowledge
they even find abstractions like “food” (vs. specializations like “beef” or “corn”).
Thus, in our approach, partitional clustering reduces first the size of the problem
such that it becomes tractable for conceptual clustering, which then facilitates the
understanding of the results.},

@article{stumme03off,
  abstract = {In the last years, the main orientation of Formal Concept Analysis
    (FCA) has turned from mathematics towards computer science. This
    article provides a review of this new orientation and analyzes why
    and how FCA and computer science attracted each other. It discusses
    FCA as a knowledge representation formalism using five knowledge
    representation principles provided by Davis, Shrobe, and Szolovits
    (1993). It then studies how and why mathematics-based researchers
    got attracted by computer science. We will argue for continuing this
    trend by integrating the two research areas FCA and Ontology Engineering.

    The second part of the article discusses three lines of research which
    witness the new orientation of Formal Concept Analysis: FCA as a
    conceptual clustering technique and its application for supporting
    the merging of ontologies; the efficient computation of association
    rules and the structuring of the results; and the visualization and
    management of conceptual hierarchies and ontologies including its
    application in an email management system.},

  abstract = {Association rules are a popular knowledge discovery technique for
warehouse basket analysis. They indicate which items of the
warehouse are frequently bought together. The problem of association
rule mining has first been stated in 1993. Five years later, several
research groups discovered that this problem has a strong connection
to Formal Concept Analysis (FCA). In this survey, we will first
introduce some basic ideas of this connection along a specific
algorithm, \titanic, and show how FCA helps in reducing the number
of resulting rules without loss of information, before giving a
general overview over the history and state of the art of applying
FCA for association rule mining.},
