Während sich die Börsen in den mittel- und osteuropäischen Transformationsökonomien in den vergangenen Jahren im Aufbau befanden, wandelten sich die westeuropäischen Börsen von nationalen Monopolisten zu professionellen Dienst-leistern. Bei diesem Vorgang wirkte der Wettbewerb zwischen den unterschiedlichen Börsenplätzen als Katalysator und löste eine Konsolidierungswelle aus.

Second, if this integration succeeds, how valuable is the information that user feedback provides? For the tasks of retrieval evaluation and query disambiguation, the talk will quantify by how much user feedback can save human annotator effort and improve retrieval quality respectively. Bio. Thorsten Joachims is an Associate Professor in the Department of Computer Science at Cornell University. In 2001, he finished his dissertation with the title “The Maximum-Margin Approach to Learning Text Classifiers: Methods, Theory, and Algorithms”, advised by Prof.

Directory as it goes to deeper levels. This is caused by propagations of errors at early stages involving the ancestors in classifications. In [7], two refinement methods using cross-validation and metafeatures which are the predication of children of a target node are introduced to deal with error propagation and nonlinearity of general concepts in high level. Text Classification for a Large-Scale Taxonomy 9 In [9], shrinkage approach was proposed for hierarchical classification. Probabilities of words for a class corresponding to a leaf node are calculated for the parents up to the root and combined with a set of parameters.

Li et al. Table 3. Results for clustering the documents under the nodes “Top/Computers/Programming/Languages”, “Top/Arts” and “Top”. indicates Folk-LDA achieves a significant improvement over the LDA-M method. no. 248 subcategories of “Top” node have little in common and people seldom tag them with common tag terms. This dramatically reduces the factors that lead to topic drift in merged tag document. 4 Comparison of Clustering Based on Tags and/or Words Since user-related tag expansion greatly improves the performance of tag based web document clustering, it is natural to consider the following questions:(1)Are tags a better resource than words on document clustering?
