Part-of-speech (POS) induction is one of the most popular tasks in research on unsupervised NLP Various unsupervised and semisupervised methods have been proposed to tag an unseen language. However, many of them require some partial understanding of the target language because they rely on dictionaries or parallel corpora such as the Bible. In this paper, we propose a different method named delexicalized tagging, for which we only need a raw corpus of the target language. We transfer tagging models trained on annotated corpora of one or more resource-rich languages. We employ language-independent features such as word length, frequency, neighborhood entropy, character classes (alphabetic vs. numeric vs. punctuation) etc. We demonstrate that such features can, to certain extent, serve as predictors of the part of speech, represented by the universal POS tag (Das and Petrov, 2011).
Metamorphic testing is a testing method for problems without test oracles. Integration testing allows for detecting errors in complex systems that may not be found during the testing of their components. In this paper...

The measurements and calculations have aimed at the verification of codes and data bases applied in modeling of transmutations in the spallation target and the resulting radioactivity. In experiments cylindrical Pb targets were exposed to the beam of 660 MeV protons. Using gamma-spectrometry, a number of radionuclides were identified in Pb and Bi samples irradiated in the targets. Axial and radial distributions of several nuclides production rates were determined. Three types of the distribution shapes were distinguished: Bi isotopes, medium and heavier nuclides. The distributions of Bi isotopes reveal a sharp characteristic peak about 30cm inside the target. The comparison of experimental results with calculations (MCNPX, FLUKA and LAHET) shows agreement within one order of magnitude, at the worst. Almost always the C/E ratio is between 3 and 1/3. However, no single code and/or reaction model yields good results for all examined nuclides. (c) 2006 Elsevier B.V. All rights reserved.
