  abstract = {The acquisition of explicit semantics is still a research challenge.
Approaches for the extraction of semantics focus mostly on learning
hierarchical hypernym-hyponym relations. The extraction of co-hyponym and
co-meronym sibling semantics is performed to a much lesser extent, though
they are not less important in ontology engineering.
In this paper we will describe and evaluate the XTREEM-SG (Xhtml TREE
Mining - for Sibling Groups) approach on finding sibling semantics from semistructured
Web documents. XTREEM takes advantage of the added value of
mark-up, available in web content, for grouping text siblings. We will show that
this grouping is semantically meaningful. The XTREEM-SG approach has the
advantage that it is domain and language independent; it does not rely on
background knowledge, NLP software or training.
In this paper we apply the XTREEM-SG approach and evaluate against the
reference semantics from two golden standard ontologies. We investigate how
variations on input, parameters and reference influence the obtained results on
structuring a closed vocabulary on sibling relations. Earlier methods that
evaluate sibling relations against a golden standard report a 14.18% F-measure
value. Our method improves this number into 21.47%.},

  abstract = {The TFxIDF term weighting scheme is the standard approach on vectorization of textual data. For a data set where textual data stemming from web document structure is to be vectorized \cite{DBLP:conf/kdxd/BrunzelS06} the need for a enhanced term weighting scheme arose. In this publication we introduce a term weighting scheme which improves the behavior compared to the traditional TFxIDF scheme by adding a component which is based on the linguistically inspired notion of domain relevance. Domain relevance measures the degree to which a term is regarded as more relevant within a data set compared to a reference data set. By means of this external component a potential weakness of TFxIDF on non standard distributed data sets is overcome. This weighting scheme favours domain relevant terms, which can be regarded as more useful in settings where the clustering is performed to be consumed by an human supervisor e.g for semi-automatic ontology learning.},
