abstract through the interpretation of texts, and subsequent creation of social reality, mediated representations are often seen to be presented within the certain of ideological discourses that reflect the existing power structures. the main objective of this paper is to analyze television commercials with an emphasis on gender roles to decode the main elements of a dominant discourse (preferr...

I have elsewhere argued (Ariel, 2002) against the assumption that we can identify one literal meaning per sentence. Instead, I have suggested that there are (at least) three types of minimal meanings, each differently motivated. One implicit motivation behind the classical definition of literal meaning (Grice’s ‘what is said’) is a wish to capture the core content of sentences. I here examine d...

The use of forward osmosis (FO) is of growing interest for water desalination, due to its potential energy savings. However, its industrial implementation is still limited by its actual performance limitation inwater permeation and reverse salt diffusion, due to membrane properties. Assisted forward osmosis (AFO) is a new concept, aiming at pressurising the feed solution to enhance water permea...

In this paper we introduce the notion of an Open Non-uniform Cylindrical Algebraic Decomposition (NuCAD), and present an efficient model-based algorithm for constructing an Open NuCAD from an input formula. A NuCAD is a generalization of Cylindrical Algebraic Decomposition (CAD) as defined by Collins in his seminal work from the early 1970s, and as extended in concepts like Hong’s partial CAD. ...

This paper explores the differences in words and word usage in two corpora – one derived from newspaper text and the other from the web. A corpus of web pages is compiled from a controlled traversal of the web, producing a topicdiverse collection of 2 billion words of web text1. We compare this Web Corpus with the Gigaword Corpus, a 2 billion word collection of news articles. The Web Corpus is ...

Here we describe a work-in-progress approach for learning valencies of verbs in a morphologically rich language using only a morphological analyzer and an unannotated corpus. We will compare the results from applying this approach to an unannotated Arabic corpus with those achieved by processing the same text in treebank form. The approach will then be applied to an unannotated corpus from Quec...
