Our submission guesses at entailment based on word similarity between the hypotheses and the text. We attempt three kinds of comparisions: original words (with normalized dates and numbers) synonyms, and antonyms. Each of the three comparisions contributes a different weight to the entailment decision. Our results are insignificantly better than chance for the two-way comparison. However, for t...

Environmental monitoring studies produce huge amounts of concentration values of chemicals spread at distant geographical sites and during different time periods. Moreover, the content of chemicals is also estimated at different environmental compartments (i.e. air, water, sediments, biota...). All these data values are difficult to cope and evaluate in a simple and fast way using simple univar...

Removal of noise is an important step in the image restoration process, and remains a challenging problem in spite of the sophistication of recent research. Popular approaches can be categorized in various ways, a classical one of which involves minimization of variation in an image. This report presents a comparison of three such classical image denoising methods, all minimizing the variation ...

Fast and sensitive high-performance liquid chromatography (HPLC) coupled with chemometric methods was utilized to assist in the quality assessment of Cangzhu (Atractylodis Rhizoma). By comparative analysis of chromatographic profiles, twelve common peaks were selected for multivariate analysis. Principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-D...
