Due to the popularity of 3D graphics in animation and games, usage of 3D geometry deformable models increases dramatically. Despite their growing importance, these models are difficult and time consuming to build. A distance learning system for the construction of these models could greatly facilitate students to learn and practice at different…

Introduction: The goal of this study is to expand our understanding of the relationships between selected tasks, cognitive abilities and search result interfaces. The underlying objective is to understand how to select search results presentation for tasks and user contexts Method: Twenty three participants conducted four search tasks of two types…

Models of a psychological process can be difficult to discriminate experimentally because it is not easy to determine the values of the critical design variables (e.g., presentation schedule, stimulus structure) that will be most informative in differentiating them. Recent developments in sampling-based search methods in statistics make it…

Internet technology has provided people with unprecedented abilities to filter the information they encounter, leading many scholars to fear that people will be exposed to less diversity of perspectives and fragment into homogeneous interest groups. Exposure to a wide range of topics and perspectives about political information in particular is…

The purpose of this study is to examine exemplary science teachers' level of computer use, their knowledge/skills in using specific computer applications for science instruction, their use of computer-related applications/tools during their instruction, how often they required their students to use those applications in or for their science class…

Purpose: This paper aims to provide information about various digital initiatives in libraries in Thailand and especially use of Dublin Core metadata in cataloguing digitized objects in academic and government digital databases. Design/methodology/approach: The author began researching metadata use in Thailand in 2003 and 2004 while on sabbatical…

Education in Library and Information Science is a requirement to become a librarian. There are a lot of syllabi and subjects to concentrate on such as cataloguing and classification, information retrieval, knowledge management, and reference. The library as a centre of information has been developing year by year with various types of collections…

The retrieval decision problem is considered from the viewpoint of a decision theory approach. A threshold rule based on earlier rules for indexing decisions is considered and analyzed for retrieval decisions as a measure of retrieval performance. The threshold rule is seen as a good descriptive design measure of what a reasonable retrieval system…

A study of relevance through comparison of texts judged by users is reported. The relevant set of documents for each information request was characterized by textual properties. The validity of procedures and interpretations is discussed. Consideration is given to possible mechanization of the process and its possible usefulness in development of…

Part Three of this five part report on Salton's Magical Automatic Retriever of Texts (SMART) project contains four papers. The first: "Variations on the Query Splitting Technique with Relevance Feedback" by T. P. Baker discusses some experiments in relevance feedback performed with variations on the technique of query splitting. The…

The development of an automatic indexing technique, called Double KWIC (DKWIC) Coordinate Indexing, is described which extends the KWIC indexing principles to provide easy access to an additional level of specificity for information indexed under these frequently appearing terms. Chapter 2 discusses indexing terminology and some fundamental…

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. (VT)

Describes the System for Conceptual Information Summarization, Organization, and Retrieval (SCISOR), which is designed to parse and understand short newspaper stories on corporate takeovers. Highlights include issues involved in developing memory organization and retrieval components, theoretical considerations involved in the system design, and a…

Presents adaptation of a probabilistic theoretical model previously used in relevance feedback for use in automatic indexing of documents (in the sense of imitating) human indexers. Methods for model application are proposed, independence assumptions used in the model are interpreted, and the probability of a dependence model is discussed.…

Designed to measure end-users' efficacy in online searching based on their presearch experience with printed literature retrieval systems for the search topic, this experiment examined differences between manual searches preceding electronic searches and vice versa. The results were not statistically significant due to the small sample size.…
