The imbalanced sentiment distribution of microblogs induces bad performance of binary classifiers on the minority class. To address this problem, we present a semisupervised method for sentiment classification of Chinese microblogs. This method is similar to self-training, except that, a set of labeled samples is reserved for a confidence scores computing process through which samples that are ...

The concept of a uniformity was developed by A. Well and there have been several generalizations. This paper defines a point semiuniformity and gives necessary and sufficient conditions for a topological space to be point semiuniformizable. In addition, just as uniformities are associated with topological groups, a point semiuniformity is naturally associated with a semicontinuous group. This p...

We study integral vectorial functionals F(u;) ? Z f(x; u(x); Du(x))dx where f satisses quasi-convexity assumption and its growth is controlled in term of N-functions. We obtain semicontinuity results in the weak * topology of Orlicz-Sobolev spaces.

This article describes a method which allows acquiring artifact nouns in French automatically by extracting predicateargument structures. Two strategies are presented: the supervised strategy and the semi-supervised strategy. In the supervised method, the semantic classes of artifact nouns are recognized by identifying the predicate-argument structures with the syntactic patterns of the given p...

The objective of this paper is to investigate the role of the set of irrational numbers as the codomain of order-preserving functions defined on topological totally preordered sets. We will show that although the set of irrational numbers does not satisfy the Debreu property it is still nonetheless true that any lower (respectively, upper) semicontinuous total preorder representable by a real-v...

We thank the reviewer for the valuable comments. A clarification will be made that the same set up applies for laboratory instruments. Indeed the semi-continuous (SC) instrument is not identical to the lab instrument but it does measure ECOC with the same thermal/optical method. The SC instruments participated in this comparison did n0t show any systematic deviating behavior or overall poor per...

Generalized semi-infinite optimization problems (GSIP) are considered. The difference between GSIP and standard semi-infinite problems (SIP) is illustrated by examples. By applying the ’Reduction Ansatz’, optimality conditions for GSIP are derived. Numerical methods for solving GSIP are considered in comparison with methods for SIP. From a theoretical and a practical point of view it is investi...

This paper tackles the problem of semi-supervised video object segmentation, that is, segmenting an object in a sequence given its mask in the first frame. One of the main challenges in this scenario is the change of appearance of the objects of interest. Their semantics, on the other hand, do not vary. This paper investigates how to take advantage of such invariance via the introduction of a s...
