This paper looks at feature selection for ordinal text classification. Typical applications are sentiment and opinion classification, where classes have relationships based on an ordinal scale. We show that standard feature selection using Information Gain (IG) fails to identify discriminatory features, particularly when they are distributed over multiple ordinal classes. This is because inter-...

We consider a natural way of extending the Lebesgue covering dimension to various classes of infinite dimensional separable metric spaces. All spaces in this paper are assumed to be separable metric spaces. Infinite games can be used in a natural way to define ordinal valued functions on the class of separable metric spaces. One of our examples of such an ordinal function coincides in any finit...

we used various screening techniques, clustering, decision tree and generalized rule induction (association) (gri) models and molecular phylogenic relationship to search for patterns of halophi-licy and to find features contribute to halolysin salt stability. we found met was the sole n-terminal amino acid in halolysin proteins, whereas other amino acids found at this position of oth-er proteas...

The article addresses the mutual relationship between environmental improvements and improvement in social status of women. The main question of this article is: Are there any relationships between improvement in environment protection and promotion in the situation of women? The theoretical framework includes Hatfield’s view about the existence of communities between the public and private sph...
