In this paper we compare a number of Topiary-style headline generation systems. The Topiary system, developed at the University of Maryland with BBN, was the top performing headline generation system at DUC 2004. Topiary-style headlines consist of a number of general topic labels followed by a compressed version of the lead sentence of a news story. The Topiary system uses a statistical learnin...

We describe our submission to the Image Relevance Assessment Task (IRAT) at the 2012 Text REtrieval Conference (TREC) Crowdsourcing Track. Four aspects distinguish our approach: 1) an interface for cohesive, efficient topicbased relevance judging and reporting judgment confidence; 2) a variant of Welinder and Perona’s method for online crowdsourcing [17] (inferring quality of the judgments and ...

This study is mainly aimed at analyzing cohesive devices in the reading texts on Accounting at ULSA, finding out teachers’ attitudes towards cohesion teaching. Four reading texts were chosen as core materials for the analysis of the cohesive devices. Five teachers from English Department were asked to take part in the interview in order to give ideas about their attitudes towards teaching cohes...

The present study set out to investigate the effect of teaching substitution as a kind of grammatical cohesion on the true identification of confusing substitution elements with cohesive or non-cohesive roles in different contexts and also the production of modal, reporting and conditional contexts through clausal substitution acquaintance. To this end, the following procedures were taken. Firs...

While toughening and damage might seem to be two contradictory concepts for the mechanics of crack growth, they are actually the same phenomena perceived from two different vantage points. Similarly, the concepts of extrinsic and intrinsic toughening, defined in terms of whether a toughening mechanism occurs behind or ahead of a crack, depend on the definition of a crack tip that, in the absenc...

We show that many uncountable admissible ordinals (including some cardinals) as well as all countable admissible ordinals have cohesive subsets. Exactly which cardinals have cohesive subsets, however, is shown to depend on set-theoretic assumptions such as V=L or a large cardinal axiom. The study of recursion theory on the ordinals was initiated by Takeuti and then generalized by several others...

hydrodynamics and sediment transport model used to determine the longand short-term stability of dredged material mounds. This technical note (TN) introduces a new cohesive sediment transport submodel for LTFATE, which includes a combined current-wave shear stress calculation and a layered sediment bed model. LTFATE can be accessed via the Internet at the following address: http://www.wes.army....

Based on LSA’s (Latent Semantic Analysis) measuring textual coherence and Halliday and Hasan’s cohesive concepts and their categorization of cohesive devices, this paper analyzes coherent relatedness and cohesive devices of 100 Chinese students’ English writings. The results indicate that (1) LSA is proved to be an objective and appropriate method in measuring the textual coherence, and (2) clo...
