Tweets often contain a large proportion of abbreviations, alternative spellings, novel words and other non-canonical language. These features are problematic for standard language analysis tools and it can be desirable to convert them to canonical form. We propose a novel text normalization model based on learning edit operations from labeled data while incorporating features induced from unlab...

Objective: It has been suggested that some internet users spend so much time on the internet that their personal and/or professional lives suffer. This study compared the temperament and character of problematic internet users (PIU) with that of problematic drug users (PDU) among Korean adolescents and aimed to examine the personality characteristics of adolescents with internet use problems. M...

Hajdu-Cheney syndrome is a rare, probably autosomal dominant connective tissue disorder with a variable expressivity. It is characterized by an osteoporotic skeleton, acro-osteolysis, a proportionate short stature, and distinctive orofacial anomalies. The aim of this article is to focus on the orofacial manifestations in two sporadic cases and one familial case with Hajdu-Cheney syndrome. Sever...

Low-level edge detection in optical imagery can be problematic in the ATR domain where highly complex scenes are the norm. Feature detection algorithms typically take a global approach, resulting in the discovery of many fragmented lines which are not directly related to stored model information. For this domain, we have taken a top-down approach which searches an optical image for the locally ...

This paper is a preliminary exploration concerning how the ethics of research on human subjects may differ when we move from the well-discussed context of research on therapies to the less-discussed context of research on enhancements. A number of differences are described. There are some features that make such research more morally problematic in certain ways, but some of the features may act...

Background: Although problematic Internet use (PIU) is a growing problem among adolescents, few studies have examined its prevalence among university students in Iran. This study was designed to investigate the prevalence of PIU and its potential risk factors among students at Kerman University of Medical Sciences, Kerman, Iran. Methods: In a cross-sectional study, data was collected from 976 u...

Imprecise articulatory breakdown is one of the characteristics of dysarthric speech. This work attempts to develop a framework to automatically identify problematic articulatory patterns of dysarthric speakers in terms of distinctive features (DFs), which are effective for describing speech production. The identification of problematic articulatory patterns aims to assist speech therapists in d...

The key role of histopathology in analysis of a melanocytic tumor is the recognition or exclusion of a malignant melanoma. The analysis of typical features leads to a correct diagnosis in the majority of cases. However, there are cases that are problematic, because of conflicting or insufficient criteria, in which a confident diagnosis is difficult. These difficult lesions account for a large p...
