Linguistic computational model based on 2-tuples and intervals

Herrera and Mart́inez initiated a 2-tuple fuzzy linguistic representation model for computing with words.Moreover, Wang and Hao further developed a new 2-tuple fuzzy linguistic representation model to deal with the linguistic term sets that are not uniformly and symmetrically distributed. This study proposes another linguistic computational model based on 2-tuples and intervals, which we call an interval version of the 2-tuple fuzzy linguistic representation model. The proposed model possesses three steps: 1) interval numerical scale; 2) computation based on interval numbers; and 3) a generalized inverse operation of the interval numerical scale. The first step transforms linguistic terms into interval numbers, based on which the second step is executed with output as an interval number. Finally, this number is then mapped into the interval of the linguistic 2-tuples by the generalized inverse operation. This study also generalizes the numerical scale approach, presented in the Wang and Hao model, to set the interval numerical scale, by considering the context where semantics of linguistic terms are defined by interval type-2 fuzzy sets (IT2 FSs). In order to compare the proposed model with the existing linguistic computational model based on IT2 FSs, we have conducted extensive simulations. The simulations demonstrate that the results obtained by our proposal are consistent with the results of the linguistic computational model based on IT2 FSs (in some sense) in a vast majority of cases.

We need to talk

We need to talk was a collaborative creative work by the feminist collective LEVEL - Rachael Haynes, Courtney Coombs, Caitlin Franzmann, Anita Holtsclaw and Courtney Pedersen. LEVEL was commissioned by the Museum of Contemporary Art (MCA) to stage this event as part of the Re-School Program. This work utilises reflexive and discursive strategies to move beyond the script of feminism as a historical moment and back to the lived experience of feminist art as political understanding and social engagement.

We need to talk

'We need to talk' examines the discursive framework of LEVEL as a feminist art collective and engages with conversation as a strategy for bringing diverse individual voices to the forefront of the feminist discussion. The words in the audio works, were recontextualised from a series of dinner party conversations, which focused on the role of women and feminism in the 21st century. The thoughts and ideas of sixty women have been transcribed, edited and re-recorded through the artists’ individual voices. Placed in a specially constructed ‘lazy susan’, this audio installation speaks of the experience of sharing information, ideas and experiences ‘around the table’. The fabric patterns on the floor cushions have been designed from banners created in collective workshops with women in Brisbane and Melbourne, Australia, as a way of translating personal statements and political ideas into the everyday.

Question: do we need to change the racial discrimination laws?

In light of the Bolt v. Eatock case before the Racial Discrimination Commission, this article discusses calls for Australia's racial vilification laws to be amended to exclude humiliation and embarrassment as grounds for a finding of vilification.
