Q-WordNet: Extracting Polarity from WordNet Senses
This paper presents Q-WordNet, a lexical resource consisting of WordNet senses automatically annotated by positive and negative polarity. Polarity classification amounts to decide whether a text (sense, sentence, etc.) may be associated to positive or negative connotations. Polarity classification is becoming important for applications such as Opinion Mining and Sentiment Analysis, which facili...
متن کاملQ&A: Quantitative approaches to planar polarity and tissue organization
Polarity in physics is defined as 'that quality or condition of a body in virtue of which it exhibits opposite or contrasted properties or powers, in opposite or contrasted parts or directions' [1]. Examples of polarized physical systems include magnets and batteries. In biology, polarity refers to the asymmetric distribution of subcellular components, resulting in an asymmetric cell morphology...
متن کاملWiener Polarity Index of Tensor Product of Graphs
Mathematical chemistry is a branch of theoretical chemistry for discussion and prediction of the molecular structure using mathematical methods without necessarily referring to quantum mechanics. In theoretical chemistry, distance-based molecular structure descriptors are used for modeling physical, pharmacologic, biological and other properties of chemical compounds. The Wiener Polarity index ...
متن کاملQ-WordNet PPV: Simple, Robust and (almost) Unsupervised Generation of Polarity Lexicons for Multiple Languages
This paper presents a simple, robust and (almost) unsupervised dictionary-based method, qwn-ppv (Q-WordNet as Person-alized PageRanking Vector) to automatically generate polarity lexicons. We show that qwn-ppv outperforms other automatically generated lexicons for the four ex-trinsic evaluations presented here. It also shows very competitive and robust results with respect to manually annotated...
متن کاملThe Generalized Wiener Polarity Index of some Graph Operations
Let G be a simple connected graph. The generalized polarity Wiener index of G is defined as the number of unordered pairs of vertices of G whose distance is k. Some formulas are obtained for computing the generalized polarity Wiener index of the Cartesian product and the tensor product of graphs in this article.
