In a linguistic framework, several group decision making processes by direct approach are presented. These processes are designed using the linguistic ordered weighted averaging (LOWA) operator. To do so, first a study is made of the properties and the axiomatic of LOWA operator, showing the rationality of its aggregation way. And secondly, we present the use of LOWA operator to solve group dec...

In this paper, we investigate the multiple attribute group decision making (MAGDM) problems for for evaluating the computer network security with linguistic information. We utilize the pure linguistic weighted arithmetic averaging (PLWAA) operator to aggregate the linguistic information corresponding to each alternative and get the overall value of the alternatives, then rank the alternatives a...

We describe our experience in developing a discourse-annotated corpus for community-wide use. Working in the framework of Rhetorical Structure Theory, we were able to create a large annotated resource with very high consistency, using a well-defined methodology and protocol. This resource is made publicly available through the Linguistic Data Consortium to enable researchers to develop empirica...

This section considers the actual performance in poverty reduction of selected LDCs for which information is available in order to get an idea of which circumstances promote success and which do not. The analysis has to be carried out in a situation of extreme data constraint, especially for the SSA which has the largest concentration of LDCs. In view of the very different nature and extent of ...

In this paper, we define the concept of uncertain multiplicative linguistic preference relation, and introduce some operational laws of uncertain multiplicative linguistic variables. We propose some new aggregation operators including the uncertain linguistic geometric mean (ULGM) operator, uncertain linguistic weighted geometric mean (ULWGM) operator, uncertain linguistic ordered weighted geom...

Lexical representation so far has not been extensively investigated in regard to language acquisition. Existing computational linguistic systems assume that text analysis and generation take place in conditions of complete lexical knowledge. That is, no unknown elements are encountered in processing text. It turns out however, that productive as well as non-productive word combinations require ...

There are many scientific problems generated by the multiple and conflicting alternative definitions of linguistic recursion and human recursive processing that exist in the literature. The purpose of this article is to make available to the linguistic community the standard mathematical definition of recursion and to apply it to discuss linguistic recursion. As a byproduct, we obtain an insigh...

Linguistic utterances are full of errors and novel expressions, yet linguistic communication is remarkably robust. This paper presents a double-layered architecture for open-ended language processing, in which ‘diagnostics’ and ‘repairs’ operate on a meta-level for detecting and solving problems that may occur during habitual processing on a routine layer. Through concrete operational examples,...

The paper deals with words and possible alternative to words as basic units in linguistic theory, especially in interlinguistic comparison and corpus linguistics. A number of ways of defining the word are discussed and related to the analysis of linguistic corpora and to interlinguistic comparisons between corpora of spoken interaction. Problems associated with words as the basic units and alte...

This study attempted to investigate writing problems and the relationship between expert-assessment and self-assessment of writing problems. Participants were thirty four non-English faculty members of Tehran and Guilan universities. The instruments were writing an essay on the topic "What teaching strategies do you use in your classes?" in twenty five lines and filling the questionnaire of wri...
