Exploratory data analysis (EDA), data visualization, and visual analytics are essential for understanding and analyzing complex datasets. In this project, we explored these techniques and their applications in data analytics. The case discusses Tableau, a powerful data visualization tool, and Google BigQuery, a cloud-based data warehouse that…

Assistive technologies can in many ways facilitate the normal day-to-day lives of the disabled. As part of the ongoing research on assistive technologies at UTAS, Oman, that deals with augmenting and finding multimodal aspects of applications for the disabled, this paper aspires to investigate the role of deep learning in the field of image…

Learning analytics dashboards commonly visualize data about students with the aim of helping students and educators understand and make informed decisions about the learning process. To assist with making sense of complex and multidimensional data, many learning analytics systems and dashboards have relied strongly on AI algorithms based on…

Despite growing interest in data visualization and graphically aided reporting, the evaluation literature could benefit from additional guidance on systematically integrating visual communication design and marketing into comprehensive communication strategies to improve data dissemination. This article describes the role of targeted communication…

Task analytic theories of graph comprehension account for the perceptual and conceptual processes required to extract specific information from graphs. Comparatively, the processes underlying information integration have received less attention. We propose a new framework for information integration that highlights visual integration and cognitive…

Reports on a continuing investigation of intertextual networks. Describes how intertextual networks can be modeled as directed graphs and extends this to matrix representations. Discusses topological index values of these networks and speculates how topological index values might be used in the estimation of retrieval values in information…

With the number and types of documents in digital library systems increasing, tools for automatically organizing and presenting the content have to be found. While many approaches focus on topic-based organization and structuring, hardly any system incorporates automatic structural analysis and representation. Yet, genre information…

In the last 20 years, the Internet has evolved from simply conveying text and then still photographs and music to the present-day medium in which individuals are contributors and consumers of a nearly infinite number of professional and do-it-yourself videos. In this dynamic environment, new generations of Internet users are streaming video and…

Discusses browsing in the particular context of visual and multimedia (e.g., videodisc) information databases and describes a working prototype system based on a fisheye view of documents in their context. Topics discussed include selecting and presenting information, exploratory access to information, artificial intelligence, user needs, and…

Discusses methods of browsing in online public access catalogs (OPACs) and describes one method that uses information pertaining to the physical description of books from MARC records to simulate images of books on a library shelf. Electronic browsing through MARC is discussed, and methods of enhancing OPACs are reviewed. (51 references) (LRW)

Discussion of human-computer interfaces focuses on the use of graphical and direct manipulation approaches to improve the user interface. Topics discussed include information seeking; computerized search capabilities, including full-text string searches, index searches, and hypertext; Boolean expressions; dynamic or direct manipulation queries;…

Describes the Perseus project, a hypertext database of textual and visual materials for the study of classical Greek civilization. The anticipated needs of users are considered; current and potential capabilities of information technology are discussed; and the selection, organization, and presentation of materials are described. (seven…

Briefly discusses Web mining and image retrieval techniques, and then presents a summary of articles in this special issue. Articles focus on Web content mining, artificial neural networks as tools for image retrieval, content-based image retrieval systems, and personalizing the Web browsing experience using media agents. (AEF)

Discussion of accessing visual resources focuses on possibilities for subject access. Projects in North America and Europe that represent current trends in accessing visual resources are described; computer-aided retrieval strategies are reviewed, including key words, comprehensive descriptors, and optical scanning; and user needs are considered.…

Two major research streams of information science, bibliometric mapping and document retrieval combined in the literature visualization movement with the implementation of VIRI (visual information retrieval interface). The capability now exists to quickly map the citation images of thousands of persons through AuthorLink, to map displays of…
