“…One of the greatest technological advances in the last 30 years is access to web services, particularly online multimedia content (audio, video, and audio-video) [5]. Multimedia is stored in repositories that contain millions of hours of content in different formats [6]. In this sense, multimedia has become one of the most important sources of information and communication on the web [7].…”

Multimedia has become one of the most important sources of information and communication on the web. However, despite recent technological progress, people with disabilities and the elderly face difficulties accessing multimedia on the web. In some cases, these difficulties are impossible to overcome and are a fundamental cause of digital exclusion. Given the importance of this topic, several investigations on the problems of accessing multimedia resources have been carried out. Some organizations have also proposed certain standards to guide the creation and publication of accessible web content. Nevertheless, the authoring tools used in the process of publishing multimedia on the web do not offer all the accessibility features required. Authoring tools can also be used by people who do not have knowledge about web accessibility or programming, resulting in web publications lacking accessibility. This research proposes 278 novel techniques to guide authors, designers, programmers, and testers in the publication of accessible and inclusive multimedia on the web. These techniques are designed to guarantee the compliance with the recommended success criteria of Authoring Tools Accessibility Guidelines (ATAG) 2.0 of the World Wide Web Consortium. Moreover, these techniques can be used to evaluate the accessibility of the existing authoring tools used to create multimedia for the web. Additionally, we present 80 possible failures that can cause the non-fulfillment of ATAG 2.0. These failures can help authors discern what to avoid and help evaluators check whether particular multimedia is accessible. INDEX TERMS Accessibility, accessibility content, Authoring Tools Accessibility Guidelines (ATAG) 2.0, disabilities, e-learning, multimedia, techniques, World Wide Web Consortium (W3C).

“…In 2011, the results of an investigation showed that audiovisual resources can be considered accessible when they can be heard and seen by people with hearing or visual difficulties [6]. That study presented a Java-based prototype that allows the user to upload a video and select the segments for which captions are inserted.…”

a b s t r a c tThe hotel industry is one of the leading stakeholders in the tourism sector. In order to reduce the trav eler's cost of seeking accommodations, enforce the return ratio efficiency of guest rooms and enhance total operating performance, evaluating and selecting a suitable hotel location has become one of the most critical issues for the hotel industry. In this scenario, recommender services are increasingly emerg ing which employ intelligent agents and artificial intelligence to ''cut through'' unlimited information and obtain personalized solutions. Taking this assumption into account, this paper presents Sem Fit, a seman tic hotel recommendation expert system, based on the consumer's experience about recommendation provided by the system. Sem Fit uses the consumer's experience point of view in order to apply fuzzy logic techniques to relating customer and hotel characteristics, represented by means of domain ontolo gies and affect grids. After receiving a recommendation, the customer provides a valuation about the rec ommendation generated by the system. Based on these valuations, the rules of the system are updated in order to adjust the new recommendations to past user experiences. To test the validity of Sem Fit, the validation accomplished includes the interaction of the customer with the system and then the results are compared with the expert recommendation for each customer profile. Moreover, the values of preci sion and recall and F1 have been calculated, based on three points of view, to measure the degree of rel evance of the recommendations of the fuzzy system, showing that the system recommendations are on the same level as an expert in the domain.
