Language complexity in on-line health information retrieval
2020
The number of people searching for on-line health information has been steadily growing over the years so it is crucial to understand their specific requirements in order to help them finding easily and quickly the specific in-formation they are looking for. Although generic search engines are typically used by health information seekers as the starting point for searching information, they have been shown to be limited and unsatisfactory because they make generic searches, often overloading the user with the provided amount of results. Moreover, they are not able to provide specific information to different types of users. At the same time, specific search engines mostly work on medical li…
ULearn: Personalized Medical Learning on the Web for Patient Empowerment
2019
Abstract. Health literacy constitutes an important step towards patient empowerment and the Web is presently the biggest repository of medical information and, thus, the biggest medical resource to be used in the learning process. However, at present web medical information is mainly accessed through generic search engines that do not take into account the user specific needs and starting knowledge and so are not able to support learning activities tailored to the specific user requirements. This work presents “ULearn” a meta engine that supports access, understanding and learning on the Web in the medical domain based on specific user requirements and knowledge levels towards what we call …
Barriers and facilitators of older people's mHealth usage: a qualitative review of older people's views
2018
The aim of this qualitative evidence synthesis is to identify and assess existing\ud evidence on barriers to and facilitators of older people’s usage of mHealth. Existing\ud literature identified many factors that affect people’s experiences and perceptions of\ud mHealth, which are in turn influenced by their personal circumstances and biography.\ud The following themes were identified using the thematic synthesis approach: (a)\ud perception of usefulness, (b) user requirements, (c) self-efficacy, (d) sense of self and\ud control, (e) privacy and confidentiality, and (f) cost. MHealth devices and services are\ud complex interventions that have to be integrated into an older person’s life in…
Delay-oriented data traffic migration in maritime mobile communication environments
2012
Maritime ship-to-shore communication has to satisfy different user requirements while suffering dynamic communication circumstances. Satellite networks are the primary means to communicate between ship and shore. The idea of compensating the deficiency of satellite communication with other terrestrial networks is not new. However, focus was often on how to keep users always best connected, without considering respective application needs or the potential disconnections. In this paper, we propose a delay-oriented satellite data traffic migration solution, exploiting the route repetitiveness and predictability of ships, leveraging the delay tolerance of many communication applications, with t…
General model for boring tool optimization
2016
Optimizing a tool (and therefore those for boring) consist in improving its performance through maximizing the objective functions chosen by the designer and/or by user. In order to define and to implement the proposed objective functions, contribute numerous features and performance required by tool users. Incorporation of new features makes the cutting tool to be competitive in the market and to meet user requirements.
Facilitating Access to Health Web Pages with Different Language Complexity Levels
2019
The number of people looking for health information on the Internet is constantly growing. When searching for health information, different types of users, such as patients, clinicians or medical researchers, have different needs and should easily find the information they are looking for based on their specific requirements. However, generic search engines do not make any distinction among the users and, often, overload them with the provided amount of information. On the other hand, specific search engines mostly work on medical literature and specialized web sites are often not free and contain focused information built by hand. This paper presents a method to facilitate the search of he…
Investigating teachers motivation to use ICT tools in higher education
2015
There are a lot of information and communication technology (ICT) tools for education, but the motivation to use those varies from teacher to teacher. In this paper we present results of an international survey on teachers' use of ICT tools in education. The purpose of the survey was to find out what motivates teachers to use ICT tools in the context of teaching. The survey also intended to reveal which tools are used as well as the needs and requirements that are not covered by the existing tools. Most of the 45 respondents suggested that the integration of tools depends on how well they fit into the learning and teaching process and how easy it is to integrate them. The first category of …
Document Word Clouds: Visualising Web Documents as Tag Clouds to Aid Users in Relevance Decisions
2009
Περιέχει το πλήρες κείμενο Information Retrieval systems spend a great effort on determining the significant terms in a document. When, instead, a user is looking at a document he cannot benefit from such information. He has to read the text to understand which words are important. In this paper we take a look at the idea of enhancing the perception of web documents with visualisation techniques borrowed from the tag clouds of Web 2.0. Highlighting the important words in a document by using a larger font size allows to get a quick impression of the relevant concepts in a text. As this process does not depend on a user query it can also be used for explorative search. A user study showed, th…
LifeRescue Software Prototype for Supporting Emergency Responders During Fire Emergency Response: A Usability and User Requirements Evaluation
2017
For an efficient emergency response, emergency responders (ERs) should exchange information with one another to obtain an adequate understanding and common operational picture of the emergency situation. Despite the current developments on information systems, many ERs are unable to get access to the relevant information as the data is heterogeneous and distributed at different places and due to security and privacy barriers. As a result, ERs are unable to coordinate well and to make good decisions. Therefore, to overcome these difficulties, a web-based application called LifeRescue was developed for supporting easy information access during emergency search and rescue operation. The goal o…
Tailored retrieval of health information from the web for facilitating communication and empowerment of elderly people
2020
A patient, nowadays, acquires health information from the Web mainly through a “human-to-machine” communication process with a generic search engine. This, in turn, affects, positively or negatively, his/her empowerment level and the “human-to-human” communication process that occurs between a patient and a healthcare professional such as a doctor. A generic communication process can be modelled by considering its syntactic-technical, semantic-meaning, and pragmatic-effectiveness levels and an efficacious communication occurs when all the communication levels are fully addressed. In the case of retrieval of health information from the Web, although a generic search engine is able to work at…
