We present an unsupervised approach to part-of-speech tagging based on projections of tags in a word-aligned bilingual parallel corpus. In contrast to the existing state-of-the-art approach of Das and Petrov, we have developed a substantially simpler method by automatically identifying “good” training sentences from the parallel corpus and applying self-training. In experimental results on eigh...

Introduction-This an in-depth investigation of the relationship between some new aspects of positive family history (FH) of coronary artery disease (CAD) and other risk factors related to CAD in patients with acute myocardial infarction (AMI). MethodThe data of 200 patients with AMI and positive FH of CAD (FH Pos.)as case groupand 200 AMI patients without FH of CAD -as control group(FH Neg.) we...

Over the past 6 years, a revised classification of the streptococci and enterococci, based primarily on molecular techniques such as 16S rRNA sequencing and DNA-DNA hybridization, emerged. However, little attention was placed on routine physiological tests that could be used in food and clinical laboratories to differentiate between species of a new genus, Enterococcus, and fecal Streptococcus ...

In this paper, part-of-speech (POS) information is used to improve the performance of a Japanese language model (LM). The POS bigram is used to tackle the sparseness problem of the training data. Additionally, due to the characteristics of the Japanese language, part of the Japanese syntax information can be integrated into the POS bigram, through POS combination rules. Based on the Japanese sy...

This paper investigates the utility of an unsupervised partof-speech (PoS) system in a task oriented way. We use PoS labels as features for different supervised NLP tasks: Word Sense Disambiguation, Named Entity Recognition and Chunking. Further we explore, how much supervised tagging can gain from unsupervised tagging. A comparative evaluation between variants of systems using standard PoS, un...

BACKGROUND In the adult human prostate CD133 expression is thought to mark rare prostate epithelial stem cells and malignant tumor stem/initiating cells. Such putative stem cell populations are thought to proliferate slowly, but possess unlimited proliferative potential. Based on this, we hypothesized that CD133(pos) prostate cancer cells proliferate slower than CD133(neg) cells. METHODS Huma...

the purpose of this study was to investigate the relationship between perceived organizational support and the trait emotional intelligence with the entrepreneurial behavior of employees in jihad-e keshavarzi organization of fars province. the research method used was a survey and descriptive- correlation techniques. statistical population of this study consisted of 110 experts in jihad-e- agri...

The problem of automatically classifying the gender of a blog author has important applications in many commercial domains. Existing systems mainly use features such as words, word classes, and POS (part-ofspeech) n-grams, for classification learning. In this paper, we propose two new techniques to improve the current result. The first technique introduces a new class of features which are vari...

Abstra t. Tagging is the task of attributing to words in ontext in a text, their orresponding Part-of-Spee h (PoS) lass. In this work, we have employed Variable Length Markov Chains (VLMC) for tagging, in the hope of apturing long distan e dependen ies. We obtained one of the best PoS tagging of Portuguese, with a pre ision of 95.51%. More surprisingly, we did that with a total time of training...
