Concept hierarchies are semi-structured knowledge repositories used for organizing large amounts of documents. File systems, products taxonomies for the market place and the directories provided by Web portals are common examples of concept hierarchies. We take the perspective in which such knowledge sources are inherently distributed and we address the problem of allowing their interoperabilit...

In this paper, we analyse alignment discrepancies for discourse structures in English-German parallel data – sentence pairs, in which discourse structures in target or source texts have no alignment in the corresponding parallel sentences. The discourse-related structures are designed in form of linguistic patterns based on the information delivered by automatic part-of-speech and dependency an...

In November 2014, OPEC announced a new strategy geared towards improving its market share. Oil-market analysts interpreted this as an attempt to squeeze higher-cost producers, notably US shale oil, out of the market. Over the next year, crude oil prices crashed, with large repercussions for the global economy. We present a simple equilibrium model that explains the fundamental market factors th...

Getting Started with Ecclesiastes: Coming to Grips with Mortality Dr. Elaine Phillips, © 2013 Introduction Ecclesiastes presents the reader with alternately disturbing and oddly reassuring realities. While scholars differ as to whether these views are a comfortable fit with “orthodoxy” and debate how to label and understand the various attitudes expressed, Ecclesiastes unquestionably speaks to ...

This 24-nation European–US study (1999–2000) of the democratic political values, attitudes, and behavior of adolescents uncovers a generally high level of self-predicted future political participation as adults. Four of five14-year-olds regard themselves as future voters, and 61% predict involvement in protest activities. Moreover, law breaking as an act of protest is almost as attractive in th...

This study investigates the impact of zero pronominal anaphora for Romanian on a learning model able to distinguish between translated and non-translated texts. Even though the correct understanding of ellipsis from the source language and its mapping into the target language is essential in the translation process, zero pronominal anaphora has been scarcely investigated in the context of trans...

Intervention planning is crucial for maintenance operations in particle accelerator environments with ionizing radiation, during which the radiation dose received by maintenance workers should be reduced to a minimum. In this context, we discuss the development of a new software tool and the entailed methodology, including the visualization aspects. The software tool integrates interactive expl...

Implicit discourse relation recognition is an extremely challenging task due to the lack of indicative connectives. Various neural network architectures have been proposed for this task recently, but most of them suffer from the shortage of labeled data. In this paper, we address this problem by procuring additional training data from parallel corpora: When humans translate a text, they sometim...
