“…Similar to the findings in other databases (Nganji, 2018;Wang et al, 2021), a majority of PDF documents in Swiss repositories are not accessible. This may be partly due to the fact that the repositories themselves do not require documents to be accessible before submission.…”

“…In the past, researchers have analysed the state of accessibility in international repositories, such as Semantic Scholar and Web of Science; the analyses of PDF document accessibility in such repositories yielded results between 2 and 15% of all papers having certain minimal accessibility features (Nganji, 2018; Wang et al, 2021). However, no such evaluation has been carried out in the Swiss repositories.…”

This survey analyzes the quality of the portable document format (PDF) documents in online repositories in Switzerland, examining their accessibility for people with visual impairments. Two minimal accessibility features were analysed: the PDFs had to have tags and a hierarchical heading structure. The survey also includes interviews with the managers or heads of multiple Swiss universities' repositories to assess the general opinion and knowledge of PDF accessibility. An analysis of interviewee responses indicates an overall lack of awareness of PDF accessibility, and shows that online repositories currently have no concrete plans to address the issue. This paper concludes by presenting a set of recommendations for online repositories to improve the accessibility of their PDF documents.

“…However, the journal publishers, who should be more aware of disability and accessibility, did not consistently follow the PDF/UA accessibility requirements and WCAG 2.0 when producing PDF versions of their articles. 93 Therefore, visually impaired individuals should be provided with a mechanism for understanding the digital content and underlying semantics at multiple levels of abstractions, like the general information about the document and its elements-including tables-its structure and content, navigation in the table, and querying the table to get more details and lessen cognitive overload.…”

People access and share information over the web and in other digital environments, including digital libraries, in the form of documents such as books, articles, technical reports, etc. These documents are in a variety of formats, of which the Portable Document Format (PDF) is most widely used because of its emphasis on preserving the layout of the original material. The retrieval of relevant material from these derivative documents is challenging for information retrieval (IR) because the rich semantic structure of these documents is lost. The retrieval of important units such as images, figures, algorithms, mathematical formulas, and tables becomes a challenge. Among these elements, tables are particularly important because they can add value to the resource description, discovery, and accessibility of documents not only on the web but also in libraries if they are made retrievable and presentable to readers. Sighted users comprehend tables for sensemaking using visual cues, but blind and visually impaired users must rely on assistive technologies, including text-to-speech and screen readers, to comprehend tables. However, these technologies do not pay sufficient attention to tables in order to effectively present tables to visually impaired individuals. Therefore, ways must be found to make tables in PDF documents not only retrievable but also comprehensible. Before developing such solutions, it is necessary to review the available assistive technologies, tools, and frameworks for their capabilities, strengths, and limitations from the comprehension perspective of blind and visually impaired people, along with suitable environments like digital libraries. We found no such review article that critically and analytically presents and evaluates these technologies. To fill this gap in the literature, this review paper reports on the current state of the accessibility of PDF documents, digital libraries, assistive technologies, tools, and frameworks that make PDF tables comprehensible and accessible to blind and visually impaired people. The study findings have implications for libraries, information sciences, and information retrieval.

Virtual learning environments are commonly adopted by universitiesas classroom teaching support. One of the resources they offerare class presentations, usually in PDF files. Considering that webaccessibility is essential to allow users with some limitations tounderstand, interact, operate and navigate web content, this articlepresents an assessment of the accessibility of PDF documents madeavailable on Moodle. The methodology used a hybrid approachcomprised techniques and practices for assessing human-computerinteraction and assessing accessibility with users simulating blindness.A quantitative analysis of the data was carried out consideringthe accessibility problems faced by users in elements such as tables,graphs, mathematical formulas, expressions in foreign languagesand presentation topics. The results indicated accessibility problemsin all documents in the sample, even causing users to drop outduring the evaluations.
