Over past two decades, research challenges pervasive have evolved following rapid progress information and communication technology. Researchers are working to create an “Internet Things” that globally interconnects smart devices sensor networks. Technologies such as wireless communication, ubiquitous sensors, passive semi-passive RFID, essential monitor transport chain. “Pervasive...

Abstract This paper proposes e-doctor; a web-based application that makes automatic diagnoses about health problems. The whole procedure is based on Support Vector Machines (SVMs), which are supervised learning models analyze data and proceed to decisions, their knowledge. System administrators define specific characteristics for each problem can be diagnosed, educate the SVM by entering sample files of statistical data. After that, medical staff enter exam information patients, e-doctor an...

Purpose – Institutional repositories (IR) are usually used to archive and manage digital collections including research results, educational material, etc. Learning management systems (LMS) form a popular basis for e-learning blended learning. This paper aims study how integrate IR LMS support accessibility of disabled students with learning difficulties (dyslexic students) in higher education. Customised ontologies focusing on can be facilitate indexing, access items the repository....

The proliferation of mobile devices has led to their integration into a huge number assistive environments where they perform key role. Pervasive environments, built over wireless infrastructures, introduce new possibilities in the healthcare sector realizing anytime-anywhere access medical information paradigm. Towards this direction pervasive technology can be deployed such as home monitoring for elderly or patients. In paper we describe policy based architecture that utilizes software...

Finding the correct category (class) a new unclassified document belongs to is an interesting and difficult problem, with wide range of applications. Our methodology for narrative text classification based on two techniques: we calculate distance (similarity) between all pre-classified documents each class also similarity ‘average document’ class. In both cases use key phrases (text or terms) as distinctive features our eventually proposed method automatic extraction authority list that...

In this paper, the special needs/requirements of disabled students and cost-benefits for applying blended learning in Personalized Educational Learning Environments (PELE) Higher Education are studied. The authors describe how can form an attractive helpful framework assisting Deaf Hard-of-Hearing (D-HH) to learn communicate. described experiment integrates face-to-face, synchronous, asynchronous e-learning, bilingual teaching (oral language Sign Language) mainstream class, parallel classes,...

This paper investigates the adoption and use of electronic invoices (e-invoices) in Greek organizations. The study attempts to evaluate current practices applied implementing e-invoicing. A field research has been conducted, which is based on a structured questionnaire. target sample consisted 42 enterprises. main issues investigation include existing invoice processing practices, barriers that prevent extended e-invoicing, observed benefits from e-invoicing implementation, strategic drivers...

Purpose – The purpose of this paper is to understand the emotional state a human being by capturing speech utterances that are used during common conversation. Human beings except thinking creatures also sentimental and organisms. There six universal basic emotions plus neutral emotion: happiness, surprise, fear, sadness, anger, disgust neutral. Design/methodology/approach It proved that, given enough acoustic evidence, person can be classified an ensemble majority voting classifier....

Purpose The purpose of this paper is to introduce an interactive system that relies on the educational data generated from online Universities services assess, correct and ameliorate learning process for both students faculty. Design/methodology/approach In presented research, services, provided by a Greek University, prior, during after COVID-19 outbreak, are analyzed utilized in order offered provide better quality students. Moreover, according paths, their presence participation insights...

Probabilistic classifiers are considered to be among the most popular for machine learning community and used in many applications. Although probabilistic exhibit very good performance when individually a specific classification task, little work has been done on assessing of two or more combination same task. In this work, we classify documents using approaches: The naive Bayes classifier Maximum Entropy model. Then, combine results improve performance, merging operators, Max Harmonic Mean....
