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…

The National Institute of Mental Health created the National Database for Autism Research (NDAR) to accelerate autism knowledge through data sharing and collaboration. However, our experience using NDAR reveals systematic challenges across several aspects of data submission, selection, management, and analysis that limit utility of this resource.…

Holds that database producers and online system vendors have failed to maintain sufficient quality control over their products, and that online searchers should voice their complaints about file documentation errors, indexing inconsistencies, and incorrect data entries. (FM)

A syntax methodology provides a descriptive mechanism to enable machine readable storage and retrieval of numeric data contained in bibliographic documents. The body of this paper treats the nature of "the syntax,""the data element," and the language by which this syntax is expressed. A discussion of the methodology illustrates…

The paper describes TSAR, a current awareness or SDI system which has been developed for processing MARC records in general, but is particularly concerned with the INSPEC service. Some statistics on the frequency of occurrence of words and comments on data compression conclude the paper. (7 references) (Author/SJ)

Reviews the state of research in text mining, focusing on newer developments. The intent is to describe the disparate investigations currently included under the term text mining and provide a cohesive structure for these efforts. A summary of research identifies key organizations responsible for pushing the development of text mining. A section…

This manual presents detailed descriptions and examples of standards and techniques for formatting and documenting machine-readable data files. The descriptions of syntax and stylistic elements are independent of whether documentation is produced manually or as a machine-readable text file. The manual also discusses rules of good practice for…

As the scholarly record has grown, so have bibliographic control instruments, some of which are in machine readable form. The expense of setting up an organization for access to the machine readable data bases seems beyond the budgets of most institutions. The objective is to establish a dependable service organization to make machine readable…

Reports the findings of a study which examined the question of submitting error reports to OCLC for the purpose of database quality control, and describes ENHANCE, a program that would provide online error correction capability for member libraries. Eight references are cited. (FM)

This document explains recent developments in computer science and information systems of interest to the educational manager. A brief history of computers is included, together with an examination of modern computers' capabilities. Various features of card, tape, and disk information storage systems are presented. The importance of time-sharing…

Discusses the new languages and software packages that make up data base management systems, outlines the characteristics of the systems, and examines the benefits claimed for them. (IRT)

This is a progress report on a project attempting to design a system of compacting text for storage appropriate to disc oriented demand searching. After noting a number of previously designed methods of compression, it offers a tentative solution which couples a dictionary of most frequent character-strings with a set of variable-length codes. The…

Northwestern University's Remote Information Query System (RIQS), an information storage and retrieval system characterized by a mixture of data structures for the internal record organization, is discussed. On-line and batch mode search capabilities handle both textual and quantitative information. Other system characteristics, capabilities and…

Four operational systems for searching and retrieving information from the ERIC data base are described. (NH)

This manual on microcomputer-based database management programs provides a description of the key characteristics of database software as well as guidelines for designing a database, uses of database programs, and selecting the right software. Three sets of concepts related to database management are listed and explained: creating a database,…
