The aim of this study was to investigate the Web-based information behaviour of high school learners in Oshana Region in Namibia. The study also considerd the challenges faced by learners when searching the Web for information. For many years in the history of library and information services, print-based information had been the main source of information. However, since the emergence of the Internet and its rapid development, the Internet has provided an almost unlimited pool of Web-based resources, thus becoming a powerful source of information. The Web is now established as the main medium for the wide dissemination of information across the Internet. Within the academic context learners throughout the world are able to retrieve seemingly endless volumes of information across all disciplines and from all over the globe. It is therefore important to study the behavior of young people in relation to Web-based information because it is today one of their most important sources of knowledge. The findings of this study could assist in curriculum design, especially with regard to Basic Information Science (a subject offered in schools in Namibia), which incorporates information literacy and information-seeking skills development. In addition the study provides some insight into the information and computer literacy levels of learners and proposes ways of responding to these, thus assisting in further developing these important literacies. The study was guided by Wilson’s (1999) model of information behaviour. The model attempts to describe an information-seeking activity and suggests relationships among stages in information-seeking behaviour. The study has adopted a quantitative approach as its methodology. Data from a total of 160 respondents was collected using a questionnaire that consisted of both open ended and closed questions. The study’s research questions investigate how, where and when do Grade 12 learners access the Internet, for what purposes do Grade 12 learners use the Web when looking for information, how do Grade 12 learners search for information on the Web, what are the Web information searching skills of Grade 12 learners, what sources of information on the Web do Grade 12 learners use, how do Grade 12 learners evaluate and use information found on the Web, and what are the challenges faced by Grade 12 learners when searching the Web for information. The survey concentrated on Matric learners (grade 12) from Mweshipandeka HS and Gabriel Taapopi SSS in the Oshana region of Namibia. The results were analysed using SPSS as a tool for data analysis. An interpretation of the findings of this study shows that learners Web-searching skills are inadequate. Overall, there was a high level of familiarity with various Web-information sources such as search engines, although users limited themselves mainly to a few sources such as the search engines Google and Yahoo and the online encyclopedia, Wikipedia. Learners were not aware of Google's limitations and of the existence of academic, often library-funded, information sources such as databases and electronic journals. The present study found strong indications that grade 12 learners lack information-evaluation skills as well as acknowledgement skills and that they are not aware of what constitutes plagiarism. This appears to be a result of poor training in schools. However, the status of learner’s access to the Internet is good. Both schools involved in this study provide learners with physical access to the Internet. / Thesis (M.I.S.)-University of KwaZulu-Natal, Pietermaritzburg, 2013.

Thesis (MSc)--University of Stellenbosch, 2004. / ENGLISH ABSTRACT: We present a system that uses statistical machine learning to identify and extract bibliography information from scientific literature. Techniques for finding and gathering useful information from the ever growing volume of knowledge on the World Wide Web (WWW), are investigated. We use hidden Markov models both for recognition of bibliography styles and extraction of bibliographic information with an accuracy of up to 97%. The accuracy with which we are able to extract this information allows us to present a case study in which we apply methods of citation analysis to information extracted from three areas of machine learning. We use this information to identify core sets of papers that have made significant contributions to the fields of hidden Markov models, neural networks and recurrent neural networks. / AFRIKAANSE OPSOMMING: Ons bied 'n sisteem aan wat gebruik maak van statistiese masjiene wat leer om bibliografiese inligting uit wetenskaplikke literatuur te identifiseer en ontgin. Tegnieke wat aangewend word vir die verkenning en insameling van nuttige inligting vanaf die snel groeiende kennisbron van die WWW, word ondersoek. Ons gebruik verskuilde Markov modelle vir die herkenning van verwysingsstyl en ontginning van verwysingsinligting met 'n akuraatheidspeil van to 97%. Hierdie hoë ontginningsakuraatheid stelons in staat om 'n toepassing van die tegniek op die veld van masjiene wat leer toe te pas. Ons rapporteer hoe ons die tegnieke gebruik het om literatuur wat beduidende bydraes in die velde van verskuilde Markov modelle, neurale netwerke en terugkerende neurale netwerke, te identifiseer.

Research shows children in an online environment often search by browsing, which relies heavily on recognition and content knowledge, so catalog systems for children must use effective symbols or pictorial representations, which correspond with children's own cognitive schema and level of recognition knowledge. This study was designed to look at the success of young children (ages 5 to 8) in searching 3 online public library catalogs designed for them, and it focused specifically on the pictorial representations and text descriptors used in the systems' browsing hierarchy. The research sought answer whether young children (ages 5 to 8) are really poor searchers because of cognitive development and lack of technology skills or if system design is the major reason for poor search results; i.e., Do current children's online catalog designs function in a manner that is compatible with information seeking by children? Although these results can not be generalized, this study indicates that there was a disconnect between the cognitive abilities of young users and catalog design. The study looked at search success on the 3 catalogs in relation to the catalog characteristics and individual user characteristics and makes 3 significant contributions to the field of library and information science. The first contribution is the modification of an existing model posed by Cooper and O'Connor and modified by Abbas (2002). The second significant contribution is the proposal of a new model, Creel's second best choice (SBC) model, that addresses the cognitive gap and design flaws that impact the choices participants made. The third significant contribution is that this study addresses and fills a gap in the literature.

The purpose of this research was firstly to compare the differences in online performance between two groups trained to use the Online Public Access Catalogue at the M L Sultan Technikon using two different types of instruction, namely the teaching methods of concept-based and procedural instruction. Secondly, the objective of the research was to compare these two teaching methods in relation to first year students at the M L Sultan Technikon with differing levels of library experience, computer experience and English language experience. To meet the objectives of the research, literature was reviewed and analysed from various sources. Original research was conducted using the method of a quasi-experiment. A random sample of 120 students were split between two teaching conditions, with sixty participants in a concept-based teaching condition and sixty participants in a procedural teaching condition. Research instruments used were a background questionnaire to collect demographic information, a pre-and post test to evaluate significant differences between the teaching methods, an evaluation questionnaire to collect affective responses, direct observation, and transaction log monitoring of the searches conducted. In a one-hour lecture the concept-based group were taught general search concepts using model-based instruction techniques and the procedural lecture demonstrated methods of searching in a step-by-step fashion. Data analysis made use of Microsoft Access 97 and Excell 97 software to code and verify the data, and the Statistical Package for the Social Sciences (SPSS), v9.0 to conduct statistical analysis. The research found that first year students were generally inexperienced in the use of the online information retrieval system. The majority of the participants in the study did not have any computer experience, and made use of English as a second language. Others, although not in the majority were found to have low levels of library experience. Performance on pre-tests were generally low for these participants while those who had experience in the use of libraries, computers and who regarded English as a first language were able to make fair use of the system for simple tasks such as author and title. This suggested that prerequisite competencies needed for online searching were, library literacy, computer literacy and some proficiency in the use of English. Performance on search tasks found no significant differences on simple tasks between the teaching conditions. However, variances in performance as a result of individual differences were found. On difficult tasks participants fared better with concept-based instruction resulting in significant differences in performance. The findings of this research supported the need for online instruction to novice end-users, taking cognisance of the need for suitable venues equipped with adequate hardware, provision of staff, and allocation of sufficient time for such instruction. The research proposes that model-based teaching be encouraged, especially for difficult tasks. In the decisions made however, instruction must take note of the background of participants. Further proposals for instruction and other related aspects are discussed in the research. / Thesis (Ph.D.)-University of Natal, Pietermaritzburg, 1999.
