What Can We Learn from Quality Requirements in ISO/TS 82304-2 for Evaluating Conversational Agents in Healthcare?
Evaluating conversational agents (CA) that are supposed to be applied in healthcare and ensuring their quality is essential to avoid patient harm. However, most researchers only study usability and use the CA in clinical trials before conducting such careful evaluation. In previous work, consensus on metrics for evaluating healthcare CA have been found. However, the metrics are still too generic to form an evaluation framework. In this work, we try to link the ISO technical specification ISO/TS 82304-2 Quality Requirements for Health and Wellness Apps to the set of metrics to come a step closer towards an evaluation framework. We identify three links between ISO requirements and the set of metrics, namely accessibility, usability, and security. Although the technical specification rather lists aspects to be considered during development instead of concrete metrics for studying the quality, we can link to some aspects that are also of interest for health CA evaluation. For example, measuring the readability for ensuring accessibility or implementing the Web Content Accessibility Guidelines are two aspects of relevance for health CA
Constructing experimental indicators for Open Access documents
The ongoing paradigm change in the scholarly publication system ('science is
turning to e-science') makes it necessary to construct alternative evaluation
criteria/metrics which appropriately take into account the unique
characteristics of electronic publications and other research output in digital
formats. Today, major parts of scholarly Open Access (OA) publications and the
self-archiving area are not well covered in the traditional citation and
indexing databases. The growing share and importance of freely accessible
research output demands new approaches/metrics for measuring and for evaluating
of these new types of scientific publications. In this paper we propose a
simple quantitative method which establishes indicators by measuring the
access/download pattern of OA documents and other web entities of a single web
server. The experimental indicators (search engine, backlink and direct access
indicator) are constructed based on standard local web usage data. This new
type of web-based indicator is developed to model the specific demand for
better study/evaluation of the accessibility, visibility and interlinking of
open accessible documents. We conclude that e-science will need new stable
e-indicators.Comment: 9 pages, 3 figure
Top 10 Law School Home Pages of 2012
For a fourth consecutive year, every website home page of every ABA-accredited law school is evaluated and ranked based on objective criteria. The goal is to identify well-executed sites adopting best practices. For the 2012 report, twenty-six elements are evaluated across these three categories: Design Patterns and Metadata, Accessibility and Validation, & Marketing and Communications. For 2012, there are four new elements, two prior elements have been combined, and one element was dropped.
For 2012, forty-six schools now use the HTML5 doctype, which is up from thirteen in 2011 and just one in 2010. Eighteen schools achieve perfect scores in an adjusted web accessibility evaluation, which is a slight increase over previous years. One of the new elements awards points for use of Responsive Web Design practices, which is a page layout method that shifts the order and number of elements on a page, based on the screen size displaying the content. Our survey discovered fourteen home pages using responsive web design.
As has been the case since this annual study launched in 2009, there is still no objective way to account for good taste. For interpreting these results, please decide for yourself whether any home page is greater or less than the sum of its evaluated elements

On the sustainability of web systems evolution
In the last twenty years, the evolution of web systems has been driven along three dimensions: the processes used to develop, evolve, maintain and re-engineer the systems themselves; the end products (the pages, content and links) of such processes; and finally the people dimension, with the extraordinary shift in how developers and users shape, interact and maintain the code and content that they put online. This paper reviews the questions that each of these dimensions has addressed in the past, and indicates which ones will need to be addressed in the future, in order for web system evolution to be sustainable. We show that the study on websites evolution has shifted from server- to client-side, focusing on better technologies and processes, and that the users becoming creators of content open several open questions, in particular the issue of credibility of the content created and the sustainability of such resources in the long term
Utilising content marketing metrics and social networks for academic visibility
There are numerous assumptions on research evaluation in terms of quality and relevance of academic contributions. Researchers are becoming increasingly acquainted with bibliometric indicators, including; citation analysis, impact factor, h-index, webometrics and academic social networking sites. In this light, this chapter presents a review of these concepts as it considers relevant theoretical underpinnings that are related to the content marketing of scholars. Therefore, this contribution critically evaluates previous papers that revolve on the subject of academic reputation as it deliberates on the individual researchers’ personal branding. It also explains how metrics are currently being used to rank the academic standing of journals as well as higher educational institutions. In a nutshell, this chapter implies that the scholarly impact depends on a number of factors including accessibility of publications, peer review of academic work as well as social networking among scholars.peer-reviewe
Global-Scale Resource Survey and Performance Monitoring of Public OGC Web Map Services
One of the most widely-implemented service standards provided by the Open
Geospatial Consortium (OGC) to the user community is the Web Map Service (WMS).
WMS is widely employed globally, but there is limited knowledge of the global
distribution, adoption status or the service quality of these online WMS
resources. To fill this void, we investigated global WMSs resources and
performed distributed performance monitoring of these services. This paper
explicates a distributed monitoring framework that was used to monitor 46,296
WMSs continuously for over one year and a crawling method to discover these
WMSs. We analyzed server locations, provider types, themes, the spatiotemporal
coverage of map layers and the service versions for 41,703 valid WMSs.
Furthermore, we appraised the stability and performance of basic operations for
1210 selected WMSs (i.e., GetCapabilities and GetMap). We discuss the major
reasons for request errors and performance issues, as well as the relationship
between service response times and the spatiotemporal distribution of client
monitoring sites. This paper will help service providers, end users and
developers of standards to grasp the status of global WMS resources, as well as
to understand the adoption status of OGC standards. The conclusions drawn in
this paper can benefit geospatial resource discovery, service performance
evaluation and guide service performance improvements.Comment: 24 pages; 15 figure

Software como um Serviço: uma plataforma eficaz para oferta de sistemas holísticos de gestão da performance
This study main objective was to assess the viability of development of a Performance Management (PM) system, delivered in the form of Software as a Service (SaaS), specific for the hospitality industry and to evaluate the benefits of its use. Software deployed in the cloud, delivered and licensed as a service, is becoming increasingly common and accepted in a business context. Although, Business Intelligence (BI) solutions are not usually distributed in the SaaS model, there are some examples that this is changing. To achieve the study objective, design science research methodology was employed in the development of a prototype. This prototype was deployed in four hotels and its results evaluated. Evaluation of the prototype was focused both on the system technical characteristics and business benefits. Results shown that hotels were very satisfied with the system and that building a prototype and making it available in the form of SaaS is a good solution to assess BI systems contribution to improve management performance.O objetivo principal deste estudo é avaliar a viabilidade de
desenvolvimento de um sistema de Gestão da Performance, entregue
sob a forma de “Software como Serviço” (SaaS), específico para o setor
hoteleiro, e também avaliar os benefícios de seu uso. O software
implantado na cloud, entregue e licenciado como um serviço, é cada vez
mais aceite num contexto de negócios. Todavia, não é comum que
soluções de Business Intelligence (BI) sejam distribuídas neste modelo
SaaS. No entanto, existem alguns exemplos de que isso se está a alterar.
Para atingir o objetivo do estudo, foi utilizada Design Science Research
como metodologia de pesquisa científica para desenvolvimento de um
protótipo. Este protótipo foi implementado em quatro hotéis para que
os seus resultados pudessem ser avaliados. A avaliação foi focada tanto
nas características técnicas do sistema como nos benefícios para o
negócio. Os resultados mostraram que os hotéis estavam muito
satisfeitos com o sistema e que construir um protótipo e disponibilizá-lo sob a forma de SaaS é uma boa solução para avaliar a contribuição
dos sistemas de BI para melhorar o desempenho da gestão.info:eu-repo/semantics/publishedVersio
Measuring and comparing the reliability of the structured walkthrough evaluation method with novices and experts
Effective evaluation of websites for accessibility remains problematic. Automated evaluation tools still require a significant manual element. There is also a significant expertise and evaluator effect. The Structured Walkthrough method is the translation of a manual, expert accessibility evaluation process adapted for use by novices. The method is embedded in the Accessibility Evaluation Assistant (AEA), a web accessibility knowledge management tool. Previous trials examined the pedagogical potential of the tool when incorporated into an undergraduate computing curriculum. The results of the evaluations carried out by novices yielded promising, consistent levels of validity and reliability. This paper presents the results of an empirical study that compares the reliability of accessibility evaluations produced by two groups (novices and experts). The main results of this study indicate that overall reliability of expert evaluations was 76% compared to 65% for evaluations produced by novices. The potential of the Structured Walkthrough method as a useful and viable tool for expert evaluators is also examined. Copyright 2014 ACM
