In this assignment, we look at the problem of Named Entity Recognition (NER), which is a sequence labeling task. We approach the problem using chain CRF model. Further, we compare the CRF model to structured SVM, in terms of F1 score, learning curve, training time and variation across multiple runs.

background: dietary diversity score (dds) measurement was used to assessment of diet quality in different disease like cardiovascular disease. one way to improve the cardiovascular patient's ability is cardiac rehabilitation program that include exercise training, nutrition consultation and psychological treatment. no study was designed to compare the dds before and after dietary consultation a...

objective: to evaluate the adnexal masses with conventional gray scale and color doppler flow imaging and to assess their diagnostic reliability to differentiate benign and malignant adnexal masses. materials and methods: we evaluated 30 patients with adnexal mass. morphological characterization of the mass was done using sassone score. color doppler parameters noted down in each patient and ca...

the purpose of this study was to analyse the prevalence of postmenopausal osteoporosis risk factors and to analyse the t-score variability in spine and hip according to the associated risk factors.this is a retrospective study (2003-2007) including 177 female patients with postmenopausal osteoporosis. the patients were separated in seven groups according to the number of risk factors per case. ...

serum level of zinc, copper, β-carotene, vitamin a, and concentrations of zn and cu in hoof of 97multiparous holstein dairy cows with different locomotion scores (lss) were evaluated. simultaneously, znand cu concentrations of close up, fresh and high yielding cattle rations were 77, 94, 75 and 31, 28, 22 ppm, respectively. based on lss, despite normal serum copper levels in all three groups, w...

the objective of the present study was to determine factors affecting body condition score (bcs) and its association with productive and reproductive performances in holstein cows. mixed model analysis was performed on monthly records of bcs from april 2006 to july 2012 comprising 34666 records from 3134 dairy cows in a large commercial dairy herd under arid climatic conditions of isfahan in ir...

Background: Resection of the petrous temporal bone to various degrees provides different levels of access to lesions of the posterior fossa. However, precise distances of petrosal bone are not still clearly described due to the numerous variations of them which may lead to serious complications during transpetrosal surgeries. Objective: Our objective was to evaluate different distances of tempo...

INTRODUCTION Both patient- and context-specific factors may explain the conflicting evidence regarding glucose control in critically ill patients. Blood glucose variability appears to correlate with mortality, but this variability may be an indicator of disease severity, rather than an independent predictor of mortality. We assessed blood glucose coefficient of variation as an independent predi...
