    Online Tutorial for Micro Cdsiisis Software
    (Addis Ababa University, 1995-05) Fissaha, Sisay; Alemayehu, Nega (PhD)
    User assistance through online help or tutorial fac ilities are among the major considerations in des igning a user interface which in turn is the major factor for successful utilization of a software. Micro CDS/ISIS is an infomlation retrieval software package developed by UNESCO and distributed free of cost to· non-profit making organization. In spite of its free availabiliry and large number of users , use of the software has been severely limited by a number of factors , --------cchieramonp hemis-la-cIc-oradequate-user-assistalIce-and-insrructionLhrough-orrline-help-or---i tutorial facilities. This thesis is an attempt to design and develop an online tutorial faciliry for Micro CDS/ISIS software which is believed to contribute greatly to ease of use and learning the software. In accomplishing this task, the software has been analyzed and described in terms of its major functions. Survey of the available developmental approaches has also been conducted and the one appropriate for the current work has been adopted. The tutorial consists of twelve lessons . It is developed using Turbo Vision which is an object oriented application framework for windowing programs. Although all the lessons have been designed, due to time constraints only the first three lessons have been programmed. However, the major design features proposed for the tutorial have been incorporated in these three lessons. Among the features that the tutorial provides is use of menus to provide smooth access ro the tutorial lessons , and provision of control button that enables the learner to control the pace of the tutorial , linking of the concepts thereby enabling the learner to get more information on related concepts, use of animated windows and highlights in drawing attention and moti vation of learner etc .

    Retrospective Conversion of Card Catalogues to Online Catalogue by using OCR Technology: a Case of Addis Ababa University Libraries
    (Addis Ababa University, 1997-06) Hundie, Kebede; Chowdhury, G.G(PhD); Fissaha, Sisay
    Conversion of card catalogues to a computerized catalogue, called retrospective conversion or RECON, is the primary hurdle of effective library automation. There are several options for RECON, but recent advances in OCR technology make it a prominent alternative. This thesis has mainly examined technical feasibility of the OCR technology for RECON with particular reference to Addis Ababa University libraries' union catalogue. The thesis reviews the various options for RECON in the context of Addis Ababa University Library System. It also reviews technological advancements of optical scanning and OCR technology stressing on document scanning and OCR with particular reference to their application in libraries, particularly RECON. An introduction to the Addis Ababa University Library System gives an overview of the library system with particular reference to its cataloguing department and cataloguing practices followed therein, and automation plan of the library system. Two sets of catalogue cards, each consisting 115 added up to 230, were chosen from the union catalogue for this study. The sets of cards consisted of main entries made under name of personal author (40 each), under title (40 each), and corporate body (35 each). A prototype program, called PABBE, was written in C++ using the first set of cards. The various steps include: scanning and conversion of the cards to ASCII text files, analysing of the files, manual editing of the files, called preprocessing, if necessary, writing and running the program creating output records consisting of each bibliographic item preceded by an iv appropriate field identifier. It was noted that the success of the prototype depends much on the accuracy of OCR software, consistency of information on card catalogues, and quality of card catalogues. The prototype was tested with the second set of catalogue cards; and the results are discussed. It was found out that the performance of the prototype program is encouraging. The thesis also highlights implementation strategy for the RECON using OCR technology. Finally, some conclusions and recommendations for further studies are forwarded. v
