Named‐entity recognition (NER), a framework, known as the acquisitive information extraction framework, is proposed as an approach to cover information extraction (IE) tasks. Designing a system for IE tasks requires a group of experts in various domains such as natural language processing, machine learning, software engineering, and data science. T...

A parsimonious convolutional neural network (CNN) for text document classification that replicates the ease of use and high classification performance of linear methods is presented. This new CNN architecture can leverage locally trained latent semantic analysis (LSA) word vectors. The architecture is based on parallel 1D convolutional layers with...

While machines can discover semantic relationships in natural written language, they depend on human intervention for the provision of the necessary parameters. Precise and satisfactory document representation is the key to supporting computer models in accessing the underlying meaning in written language. Automated text classification, where the o...

Only humans can understand and comprehend the actual meaning that underlies natural written language, whereas machines can form semantic relationships only after humans have provided the parameters that are necessary to model the meaning. To enable computer models to access the underlying meaning in written language, accurate and sufficient documen...

Purpose Strokes are the most common cause of long-term disability of adults in developed countries. Continuous participation in rehabilitation can alleviate some of the consequences, and support recovery of stroke patients. However, physical rehabilitation requires commitment to tedious exercise routines over lengthy periods of time, which often c...

AIM To design a fuzzy expert system to help detect and diagnose the severity of diabetic neuropathy. METHODS The research was completed in 2014 and consisted of two main phases. In the first phase, the diagnostic parameters were determined based on the literature review and by investigating specialists’ perspectives (n = 8). In the second phase, 2...

Strokes are the most widely recognized reason of long-term disability of adults in developed countries. Continuous participation in rehabilitation can alleviate some of its consequences and support recovery of stroke patients. However, physical rehabilitation requires commitment to tedious exercise routines over lengthy periods of time, which often...

Introduction Any information which is generated and saved needs to be protected against accidental or intentional losses and manipulations if it is to be used by the intended users in due time. As such, information managers have adopted numerous measures to achieve data security within data storage systems, along with the spread of information tech...

Despite extensive research efforts in stock market predictions using social media networks, there still exists a lack of credible sources of information in such media. This study presents a novel approach to measure the credibility of Twitter users in a domain of interest, namely the stock market. This study suggests a correlation between each user...

Background: Determination of minimum data set (MDS) in echocardiography reports is necessary for documentation and putting information in a standard way, and leads to the enhancement of electrocardiographic studies through having access to precise and perfect reports and also to the development of a standard database for electrocardiographic repor...

Background: Self-management skills are essential for patients with diabetes mellitus to minimise the risks of complications from their condition. The aim of this research was to develop a web-based application for self-management of type 1 diabetes, suitable for use by patients, their carers and physicians. Method: The study was comprised of two...

Background: Today, problems such as lack of filing space, the high volume of paper documents and expedite in access to patient medical records, induced to increasing of hospital’s attention to the use of imaging technique in medical record department. The aim of this study was to survey the application of document imaging for storage of medical re...

Background and purpose: Teledermatology means specialized skin care (diagnosis, treatment and follow-up) using information technology and telecommunications. This system facilitates communication between patients, doctors, nurses and primary care providers with dermatologists. The purpose of this study was to design and build a software for remote...

Stroke is the most common cause of long-Term disability of adults in developed countries. Continuous participation in rehabilitation can alleviate some of tis consequences, and support recover of stroke patients. However, physical rehabilitation requires commitment to tedious exercises routines overlengthy periods of time, which often causes patien...

Introduction: Compared with the leading countries in the field of health information management, the current laws for medical record retention in Iran are very general, vague and they are inappropriate in terms of medical records usage, and there is not any reference to retention of many special medical records. Thus, the aim of this study was to r...

Teledermatology: A comparison of reliability and accuracy of diagnoses with those in the face to face visits Hamed Mahdizadeh1, Haleh Ayatollahi 2, Nafiseh Esmaeili3, Kamkar Mehran Kamkar1 Abstract: (3705 Views) It is more than a decade that teledermatology has been considered as a potential substitute for the face to face visits. To evaluate its...

Introduction: Use of a computerised system improves the effectiveness and efficiency of a medical record department on condition that managers and medical record staff design it according to needs. Methods: The present investigation was an applied-descriptive study. A checklist was provided from professional texts, articles and internet. This check...

(Received 4 Jan, 2009 ; Accepted 1 Feb, 2009)AbstractBackground and purpose: Presently, computers and the development of information technology have resolved many limitations in the health and medical arena, and have also opened many doors to improve communication, information and ability for better patient care, in health and medical care provider...
