This paper presents an automatic annotation of spatial expressions enabling the improvement of the indexing process of non-structured geographic information. The proposed method combines the use of specific intra-sentential relationships and external resources. It relies on expanded spatial named entities recognition to deduce a symbolic representation expressed in terms of semantic features, o...

Why is it that if you know I’ll give a silly talk, it follows that you know I’ll give a talk, whereas if you doubt I’ll give a good talk, it doesn’t follow that you doubt I’ll give a talk? This pair of examples shows that the word “doubt” exhibits a special but prevalent kind of behavior known as downward entailingness — the licensing of reasoning from supersets to subsets, so to speak, but not...

Content analysis is a firmly established technique for textual data analysis. In particular, the notion of fully automatic, or at least computer assisted, content analysis has remained a desideratum among researchers working with large bodies of text, with the development of systems such as General Inquirer (Stone et al., 1966), Words (Iker and Harway, 1969), Quester (Cleveland, McTavish and Pi...

Simple Wikipedia has dominated simplification research in the past 5 years. In this opinion paper, we argue that focusing on Wikipedia limits simplification research. We back up our arguments with corpus analysis and by highlighting statements that other researchers have made in the simplification literature. We introduce a new simplification dataset that is a significant improvement over Simpl...

In this paper we present the system we submitted to the WMT13 shared task on Quality Estimation. We participated in the Task 1.1. Each translated sentence is given a score between 0 and 1. The score is obtained by using several numerical or boolean features calculated according to the source and target sentences. We perform a linear regression of the feature space against scores in the range [0...

We calculate the universal radiative QED corrections to polarized lepton scattering for general scattering cross sections in analytic form. The flavor non–singlet and singlet radiation functions are calculated to O((αL)5). The resummation of the non–singlet and singlet contributions to the QED–anomalous dimensions ∝ (α ln(x))k is performed to all orders. Numerical results are presented for the ...

We review the status of the calculation of next-to-next-to-leading order corrections to large angle Bhabha scattering in pure QED. After discussing the electron-loop and photonic corrections, we focus on the recently calculated two-loop virtual corrections involving a heavy-flavor fermion loop. We conclude by assessing the numerical impact of these corrections on the Bhabha scattering cross sec...

Process analyses are becoming more and more standard in research on computer-supported collaborative learning. This paper presents the rational as well as results of an evaluation of a tool called TagHelper, designed for streamlining the process of multi-dimensional analysis of the collaborative learning process. In comparison with a hand-coded corpus coded with a 7 dimensional coding scheme, T...

This paper proposes a method employing text mining techniques to analyze e-mails collected at a customer center. The method uses two kinds of domain-dependent knowledge. One is a key concept dictionary manually provided by human experts. The other is a concept relation dictionary automatically acquired by a fuzzy inductive learning algorithm. The method inputs the subject and the body of an e-m...

Yarbus' pioneering work in eye tracking has been influential to methodology and in demonstrating the apparent importance of task in eliciting different fixation patterns. There has been renewed interest in Yarbus' assertions on the importance of task in recent years, driven in part by a greater capability to apply quantitative methods to fixation data analysis. A number of recent research effor...
