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…

This paper is based on statistical and qualitative analysis of library and information science (LIS) literature. Our study asks the question of whether, and if so, how, and how often, the discourse generated by scholarly literature in LIS engages discussion about identity in LIS, what topics are covered, and whether the articles engage praxis, or…

Graphs are widely used to model structures and relationships of objects in various scientific and commercial fields. Chemical molecules, proteins, malware system-call dependencies and three-dimensional mechanical parts are all modeled as graphs. In this dissertation, we propose to mine and index those graph data to enable fast and scalable search.…

The Experimental Ecological Reserves Project has begun a comprehensive attempt to inventory the Nation's environmental research sites in preparation for establishing a network. This network will provide opportunities for long-term, manipulative, ecological research and establish an ecological data base. (BT)

Discusses the retrieval dimensions of data collection activity online and their influence on the research evaluation outcome to reinforce the link between online retrieval and bibliometrics. Topics include publication counts; citation analyses; citation databases from the Institute for Scientific Information; and data set isolation. (Author/LRW)

Discusses the development of multiobject databases called large data constructs (LDC), which may contain images and recorded or synthesized voice as well as text. Virtual reality and cyberspace are discussed, selectivity and database content are examined, database management systems are described, and retrieval options are reviewed. (three…

Describes database and index design and data collection methods for compilation of the National Tune Index, a comprehensive, multifaceted tool for research in and analysis of eighteenth century American and British secular music, restoration of early American theater works, and identification of specific tune or text fragments.

Application of a generalized data base management system enabled the new Physics-Mathematics-Astronomy Library to couple the immediate needs of moving and integrating two libraries with long-term capabilities. (Author)

Discusses efforts to locate studies on the older adult second language learner. Notes that one online and three compact disk databases were searched, using search strategies and subject headings appropriate to each particular file. Results reveal that most of the relevant studies were retrieved from the ERIC and the Linguistics and Language…

The development of a new scheme for classifying the more than 7,000 documents on reading in the ERIC/CRIER data collection is described. An original scheme, developed in the early days of the clearinghouse, provided a means for listing documents in any of 45 broad subject categories in the field of reading and for identification by grade level.…

Regardless of the inadequacies of the new information retrieval systems, and despite the serious social inequalities which will result from charging fees for information, most libraries are incorporating the computer-assisted bibliographic searching devices into their reference operations, and passing the costs on to the users.

This paper describes the organization, implementation, and outcomes of a joint effort between the Regional Laboratory for Educational Improvement of the Northeast and Islands and the Vermont State Department of Education's Database Project. In 1987, the Laboratory proposed a feasibility study to examine the means and costs of accessing…

The final report on a project to develop a standard corpus of present-day Mandarin Chinese is presented. This corpus consists of words of running text of Chinese prose printed in the Republic of China during the calendar year 1968. The corpus, although originally planned to have a total of 500 samples of 2000 words each, has only 294 samples. Each…
