The 2nd Concept Discovery in Unstructured Data workshop (CDUD)
In conjunction with ICFCA 2012 (6 - 10 May 2012, Leuven, Belgium)

Concept discovery is a Knowledge Discovery in Databases (KDD) research field that uses human-centered techniques such as Formal Concept Analysis (FCA), Biclustering, Triclustering, Conceptual Graphs etc. for gaining insight into the underlying conceptual structure of the data. Traditional machine learning techniques are mainly focusing on structured data whereas most data available resides in unstructured, often textual, form. Compared to traditional data mining techniques, human-centered instruments actively engage the domain expert in the discovery process.
This workshop welcomes papers describing innovative research on data discovery techniques. Moreover, this workshop intends to provide a forum for researchers and developers of data mining instruments, working on issues associated with analyzing unstructured data. First, we are interested in methods for transforming unstructured into semi-structured information. Unstructured information such as texts or images can be tagged, keywords can be extracted from texts by means of Natural Language Processing methods, etc. Second, in this workshop we also particularly welcome research on using human-centered instruments such as FCA to analyse unstructured and semi-structured data. Applications in which we are interested include but are not limited to Text Mining, Web Mining including forums, blogs, social sharing systems like Twitter and Facebook, mining sociological interviews, etc. We are also interested in innovative instruments for dealing with knowledge incompleteness and asymmetry. Finally, innovations which increase the expressiveness of existing methods for unstructured data analysis such as fuzzy FCA, rough FCA, Latent Semantic Analysis, probabilistic concept discovery are also of interest to this workshop.

- Data Mining (Text Mining, Graph Mining, Web Mining, Association Rules, Frequent Closed Sets, etc.)
