this paper examines the relationships between language and ideology and how ideology is constructed and presented via different language choices in english editorials published in different socio-cultural contexts. van dijk’s (2000a) ideological square in terms of representation of the self and other was applied to the editorials. through a comparative analysis of iranian, turkish and saudi ara...

In this paper a new method for knowledge extraction was presented. First, the relational knowledge representation with all crucial definitions was introduced. Second, problem statement for knowledge acquisition using relational knowledge representation was formulated. Then the modified coverage strategy was proposed. At the end a benchmark problem was considered and results were presented.

In 1998 the Adapted Ordering Method was developed for the representation theory of the superconformal algebras. This method, which proves to be very powerful, can be applied to most algebras and superalgebras, however. It allows: to determine maximal dimensions for a given type of singular vector space, to identify all singular vectors by only a few coefficients, to spot subsingular vectors and...

A common problem encountered in such disciplines as statistics, data analysis, signal processing, and neural network research, is nding a suitable representation of multivariate data. For computational and conceptual simplicity, such a representation is often sought as a linear transformation of the original data. Well-known linear transformation methods include, for example, principal componen...

In order for a subspace projection based method to be robust to local distortion and partial occlusion, the basis images generated by the method should exhibit a part-based local representation. We propose an effective partbased local representation method using ICA architecture I basis images that is robust to local distortion and partial occlusion. The proposed representation only employs loc...

There are a large number of methods for solving under-determined linear inverse problem. Many of them have very high time complexity for large datasets. We propose a new method called Two-Stage Sparse Representation (TSSR) to tackle this problem. We decompose the representing space of signals into two parts, the measurement dictionary and the sparsifying basis. The dictionary is designed to app...

The discipline of situational method engineering promotes the idea of retrieving and adapting fragments, rather than complete methodologies, to specific situations. In order to succeed in creating good methodologies that best suit given situations, fragment representation and cataloguing are very important activities. This paper presents and compares three existing approaches to fragment repres...
