Polarity shifting marked by various linguistic structures has been a challenge to automatic sentiment classification. In this paper, we propose a machine learning approach to incorporate polarity shifting information into a document-level sentiment classification system. First, a feature selection method is adopted to automatically generate the training data for a binary classifier on polarity ...

Numerical simulations of the interaction internal solitary waves (ISWs) opposite polarity are conducted by solving incompressible Euler equations under Boussinesq approximation. A double-pycnocline stratification is used. method to determine when ISWs both polarities exist also presented. The confirm previous work that same soliton-like; however, here it shown a fast ISW with as Korteweg–de Vri...

Apico-basal polarity is typical of cells present in differentiated epithelium while front-rear polarity develops in motile cells. In cancer development, the transition from epithelial to migratory polarity may be seen as the hallmark of cancer progression to an invasive and metastatic disease. Despite the morphological and functional dissimilarity, both epithelial and migratory polarity are con...

Changes in expression and localization of proteins that regulate cell and tissue polarity are frequently observed in carcinoma. However, the mechanisms by which changes in cell polarity proteins regulate carcinoma progression are not well understood. Here, we report that loss of polarity protein expression in epithelial cells primes them for cooperation with oncogenes or changes in tissue micro...

Reading text from computer screens is better when text is printed in dark letters on light background (positive polarity) than when it is printed in light letters on dark background (negative polarity). An experiment is presented that tests whether this positive polarity advantage is due to the fact that overall display luminance is typically higher for positive than for negative polarity displ...

In both Drosophila melanogaster and mammalian systems, epithelial structure and underlying cell polarity are essential for proper tissue morphogenesis and organ growth. Cell polarity interfaces with multiple cellular processes that are regulated by the phosphorylation status of large protein networks. To gain insight into the molecular mechanisms that coordinate cell polarity with tissue growth...

An efficient minimisation method is presented to find the best polarity of fixed polarity canonical orcoincidence (COC) expansions. The method derives one COC fixed polarity expansion from another adjacent polarity expansion. To reduce CPU time, it utilises bitwise operation and Gray code. Furthermore, it counts the number of “0”s in the polarity matrix rather than polarity matrix multiplicatio...

In this paper, we propose two metrics capable of modeling forms of polarity contrast: polarity divergence and polarity dimorphism. To explore their potential usefulness to the detection of verbal irony and sentiment polarity, we performed an exploratory text analysis on a corpus of figurative tweets annotated by sentiment. The results of a text analysis show that, employing two different types ...
