## 3 Methodology
### Accessibility Score Computation
#### 3.2.3 Overall Accessibility Score
In a few cases, such as broken links, links that are not properly distinguishable from text, invisible links, and links that are not validated, the added links are not accessible. To avoid unexpected accessibility problems, these issues should be considered carefully. In addition, proper hyperlinks should be inserted. _Readability:_ To ensure the readability of the text content of a web page, requirements for every type of disability should be considered, as they vary. For example, the readability level of people with cognitive disabilities is different from that of people with other disabilities. Hence, readability needs to be maintained according to different readability levels so that content may be easily understandable by people with different disability types. _Some important additional guidelines:_ A few issues with the headings and titles of web pages could hamper screen-reader users in navigating the page in an accessible manner. All headers should be maintained systematically to organize the content. Additionally, before finalizing and making web pages available for users, accessibility testing of all components should be compulsory, taking into account the requirements of people with disabilities, to validate accessibility. Maintaining the aforementioned suggestions might enhance the accessibility of web pages for people with disabilities. All of the provided suggestions in this article are based on the investigated healthcare web pages, but they also apply to any domain's web page for ensuring universal accessibility. From the analysis result of the computed scores, the expert evaluations and suggestions show that the proposed approach is effective in presenting the current accessibility situation of healthcare web pages in Hungary. This inaccessibility applies not only in Hungary, as similar scenarios have been observed in other countries in different parts of the world, as we discussed in our previous work [32]. However, this research is not free from limitations. The major limitation of this work is the consistency of the computed results. For example, websites are continuously updating; therefore, the same experimental procedure for a future updated version of a website might alter the results. Furthermore, we only considered four experts' opinions; considering more experts' opinions might influence the overall results. In addition, user evaluations have not been included in this work; thus, the incorporation of user evaluations might help in identifying other accessibility issues. ## 6 Conclusions and Future Directions

In this paper, we presented a web accessibility analysis of healthcare institution web pages in Hungary, adopting a variable-magnitude approach to compute accessibility scores. Two different approaches have been presented in this work--two different algorithms focusing on the variable-magnitude and variable-weight techniques. These two algorithms have been developed to compute accessibility scores based on the four components or terminologies (pass, fail, not tested, and not decided) obtained from two automated accessibility-testing tools, Mauve++ and TAW. The accessibility scores, \(\rho_{\text{(Mauve)}}\) and \(\rho_{\text{(Taw)}}\), were computed considering four components together with a severity factor to scale down the weight of the components, based on their importance. To generate the overall score, the computed scores of \(\rho_{\text{(Mauve)}}\) and \(\rho_{\text{(Taw)}}\) were integrated and computed into a final score. Through the introduced integrated system, the web pages of sixteen hospital and clinic were analyzed and scored. Based on the expert opinions of our accessibility specialists, we added a few suggestions to enhance the accessibility of these web pages to make them accessible for people with disabilities. Although considering expert suggestions is appropriate, it is also crucial to justify expert suggestions by considering scientists' opinions of this field.
