Purpose: Colleges and Universities have been established to provide educational services to the people. Like any other organization, the school has processes and procedures similar to business or industry that involve admissions, processing of data, and generation of reports. Those processes are made possible through a centralized system in…

Material recommender system is a significant part of e-learning systems for personalization and recommendation of appropriate materials to learners. However, in the existing recommendation algorithms, dynamic interests and multi-preference of learners and multidimensional-attribute of materials are not fully considered simultaneously. Moreover,…

Memory-based processing theories of automaticity assume that shifts from algorithmic to retrieval-based processing underlie practice effects on response times. The current work examined the extent to which individuals can exert control over the involvement of retrieval during skill acquisition and the factors that may influence control. In two…

This thesis work is mainly focused on two problems related to improving accessibility of information graphics for visually impaired users. The first problem is automated analysis of information graphics for information extraction and the second problem is multi-modal representations for accessibility. Information graphics are graphical…

The goal of this study was to examine the impact of a one-to-one program on the implementation of learning skills, information literacy, and the usage of computerized tools among students. These skills are part of the demands placed upon schools to develop 21st century competencies. Seventh and ninth grade students participated in this study…

There are six major studies of the effect of indexing depth on retrieval performance. They differ in purpose, methodology, measures, indexing language, field of study, and data base--nevertheless, all have found depth of indexing to have the same effect upon information retrieval.

Analyzes recent developments in the problem of processing queries expressed as Boolean expressions, shows that the concept of threshold values resolves the problems inherent with relevance weights, and explores possible evaluation mechanisms for document retrieval based on fuzzy set theory. Sixteen references are listed. (FM)

Investigates the feasibility of using a distance measure for automatic sequential document classification. This property of the distance measure is used to design a sequential classification algorithm which classifies key words and analyzes them separately in order to assign primary and secondary classes to a document.

Presents a new method to improve the performance of query processing in a spatial database. Experiments demonstrated that performance of database systems can be improved because both the number of objects accessed and number of objects requiring detailed inspection are much less than those in the previous approach. (AEF)

A series of five batches of twenty searches were carried out in a three year span of the INSPEC data base by the 31 Company's Information Retrieval Service. The same queries were processed manually in the corresponding volumes of Science Abstracts and comparison of the output of each search method exposed reasons for the failures. Emphasis is laid…

The relative retrieval efficiency of the title searching technique and the index term searching technique is so close that the choice of one method or the other must be primarily on economic grounds. (9 references) (Author)

In order to compare effects of input processing on information retrieval in three databases, 25 articles from a specific journal were examined. Tables and Venn diagrams show retrieval results from different manual and computer searches. The relation between document surrogates and subject matter of the documents is discussed. (SW)

An information retrieval system was developed using technical word occurrences as a basis for classification. A set of words, designated a vocabulary, was selected from the middle range of frequency listing of words occurring in an experimental sample of 94 documents. The selection produced 115 non-function words with technical definition that did…

The purpose of the study was to determine how many questions judged relevant to an article are also judged relevant using different length representations of the article, and how this proportion changes as the length of the representation changes. Several persons made relevance judgments for each of a set of articles to each of a set of questions.…
