Preface: Concept discovery is a Knowledge Discovery in Databases (KDD) research eld 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 tech- niques 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 volume contains the contributions to CDUD 2011, the International Workshop on Concept Discovery in Unstructured Data (CDUD) held in Moscow. The main goal of this workshop was to provide a forum for researchers and developers of data mining instruments working on issues with analyzing unstructured data. We are proud that we could welcome 13 valuable contributions to this volume. The majority of the accepted papers described in- novative research on data discovery in unstructured texts. Authors worked on issues such as transforming unstructured into structured information by amongst others extracting keywords and opinion words from texts with Natural Language Processing methods. Multiple authors who participated in the workshop used methods from the conceptual structures eld including Formal Concept Anal- ysis and Conceptual Graphs. Applications include but are not limited to text mining police reports, sociological de nitions, movie reviews, etc. Last but not least, we would like to thank the administration of the Higher School of Eco- nomics who took care of all arrangements to make this conference pleasant and enjoyable.   June 2011, Moscow Dmitry Ignatov Jonas Poelmans Sergei Kuznetsov
