Part Of Speech (POS) tagger is an essential preprocessing step in many natural language applications. In this paper, we investigate the best configuration of trigram Hidden Markov Model (HMM) Arabic POS tagger when small tagged corpus is available. With small training data, unknown word POS guessing is the main problem. This problem becomes more serious in languages which have huge size of voca...

BACKGROUND Airways progenitors may be involved in embryogenesis and lung repair. The characterization of these important populations may enable development of new therapeutics to treat acute or chronic lung disease. In this study, we aimed to establish the presence of bronchioloalveolar progenitors in ovine lungs and to characterize their potential to differentiate into specialized cells. RES...

BACKGROUND AND OBJECTIVES while existing research has demonstrated a positive association between exposure to point-of-sale (POS) tobacco advertising and youth smoking, there is limited evidence on the relationship between POS advertising restrictions and experimental smoking among youth. This study aims to fill this research gap by analyzing the association between POS advertising bans and you...

Calcium-bound phosphoryl oligosaccharides (POs-Ca) were prepared from potato starch. Their solubility and in situ absorbability as a calcium source were investigated by comparing with the soluble calcium compounds, calcium chloride and calcium lactate, or insoluble calcium compounds, calcium carbonate and dibasic calcium phosphate. The solubility of POs-Ca was as high as that of calcium chlorid...

Part-of-speech (POS) taggers trained on newswire perform much worse on domains such as subtitles, lyrics, or tweets. In addition, these domains are also heterogeneous, e.g., with respect to registers and dialects. In this paper, we consider the problem of learning a POS tagger for subtitles, lyrics, and tweets associated with African-American Vernacular English (AAVE). We learn from a mixture o...

This research explores the role of parts-of-speech (POS) in feature selection in text categorization. We compare the use of different POS, namely nouns, verbs, adjectives and adverbs with a feature set that contains all POS. The best results are obtained with the use of only nouns. Therefore, we make use of a WordNet-based POS feature selection approach using the nouns feature set to compare wi...

L. Rhoades and R. Eisenberger (2002) reported the meta-analytic finding of a highly statistically significant relation between perceived organizational support (POS) and performance but concluded that the reviewed studies’ methodology allowed no conclusion concerning the direction of the association. To investigate this issue, the authors assessed POS and extra-role performance 2 times, separat...

Police patrol officers were surveyed to investigate how the strength of socioemotional needs affects the relationship between perceived organizational support (POS) and work performance. The association of POS with driving-under-the-influence arrests and speeding citations generally increased with strength of the needs for esteem, affiliation, emotional support, and social approval. Patrol offi...

How to deal with part of speech (POS) tagging is a very important problem when we build a syntactic parsing system. We could preprocess the text with a POS tagger before perform parsing in a pipelined approach. Alternatively, we could perform POS tagging and parsing simultaneously in an integrated approach. Few, if any, comparisons have been made on such architecture issues for Chinese parsing....

CONTEXT Organized care management processes (CMPs) can improve health care quality for patients with chronic diseases. The Institute of Medicine of the National Academy of Sciences has called for public and private purchasers of health care to create incentives for physician organizations (POs) to use CMPs and for the government to assist POs in implementing information technology (IT) to facil...
