  ABSTRACT = {This paper describes experiments for statistical 
dependency parsing using two different parsers trained 
on a recently extended dependency treebank for Greek, 
a language with a moderately rich morphology. We show how 
scores obtained by the two parsers are influenced by morphology 
and dependency types as well as sentence and arc length. 
The best LAS obtained in these experiments was 80.16 on a test 
set with manually validated POS tags and lemmas.},

  ABSTRACT = {In this paper we give an overview of the approach adopted to add a
    layer of semantic information to the Greek Dependency Treebank [GDT].
    Our ultimate goal is to come up with a large corpus, reliably annotated
    with rich semantic structures. To this end, a corpus has been compiled
    encompassing various data sources and domains. This collection has
    been preprocessed, annotated and validated on the basis of dependency
    representation. Taking into account multi-layered annotation schemes
    designed to provide deeper representations of structure and meaning,
    we describe the methodology followed as regards the semantic layer,
    we report on the annotation process and the problems faced and we
    conclude with comments on future work and exploitation of the resulting
