What are missing in the U.S. education policy of "college for all" are supporting data and indicators on K-16 education pathways, i.e, how well all students get ready and stay on track from kindergarten through college. This study creates synthetic national longitudinal education database that helps track and support students'…

This quantitative research aims to analyze the impact of the WampServer application in Blended learning during the educational process of computing through data science, machine learning, and neural networks. WampServer is a free application that allows the creation of websites considering the use of the database. This research proposes the use of…

Research in era of data representation to contribute and improve key data policy involving the assessment of learning, training and English language competency. Students are required to communicate in English with high level impact using language and influence. The electronic technology works to assess students' questions positively enabling…

This paper is concerned with providing automatically generated online explanations to the user of a user interface or "tool" about what the interface can and cannot do, and what parameters or options are available or required with a given command. The COUSIN interface system, developed at Carnegie-Mellon, supplies a cooperative…

A primary goal of this project was to develop an interface that would provide direct access for inexperienced users to existing online bibliographic information retrieval networks. The experiment tested the concept of a virtual-system mode of access to a network of heterogeneous interactive retrieval systems and databases. An experimental…

Presents a new model of searching in online and other information systems, and reviews the literature of manual information seeking behavior for suggestions of capabilities users might like in online systems. Based on the model--called "berrypicking"--and research, suggestions are made for how new search capabilities could be implemented…

Presents a model for the a priori analysis of natural language queries which uses an algorithm to transform the query into a logical pattern that is used to determine the answerability of the query. The results of testing by a prototype system implemented in PROLOG are discussed. (20 references) (CLB)

The ideal traits for an online searcher, as identified in studies by online vendors and suppliers, are discussed: (1) curiosity and a desire to learn, (2) adaptability, (3) comfortableness with the machine interaction process, (4) ability to cope with instances of system failure, (5) patience and persistence, and (6) a logical, thorough,…

Discussion of users and information retrieval systems highlights a study that investigated the representation of users' knowledge by examining their names for objects and concepts, agreement on names, the Library of Congress Subject Headings representation for similar objects and concepts, and measurement of the similarity between these…

Previous works in English have revealed that disfluencies follow regular patterns and that incorporating them into the language model of a speech recognizer leads to lower perplexities and sometimes to a better performance. Although work on disfluency modeling has been applied outside the English community (e.g., in Japanese), as far as we know…

This paper argues that an important design principle for building expert systems is to represent all control knowledge abstractly and separately from the domain knowledge upon which it operates. Abstract control knowledge is defined as the specifications of when and how a program is to carry out its operations, such as pursuing a goal, focusing,…

Describes an image storage system for contract documentation in the Engineering Directorate of Thames Water Utilities (England) which uses optical disc storage and a relational database for indexing and retrieval of nearly 500,000 pages in compressed image format, and provides end user access through 7 workstations. Requirements, feasibility…

This discussion of educational applications of user interfaces covers the benefits of adopting database techniques in organizing multimedia materials; the evolution of user interface technology, including teletype interfaces, analogic overlay graphics, window interfaces, and adaptive systems; application design problems, including the…

The first phase of a project to design a prompting system to help semi-experienced end users to search Chemical Abstracts online, this study focused on the differences and similarities in the search approaches used by experienced users and those with less expertise. Four online searches on topics solicited from chemistry professors in small…

Describes prototype system that provides retrieval from hierarchically structured full-text databases such as legal statutes and regulations and engineering standards. Enhanced retrieval is provided through integration of three different access techniques dependent on inherent hierarchical text structure: menu, Boolean combination of keywords,…
