Šio darbo tyrimo sritis – programinės įrangos projektavimo metodai, leidžiantys išplėsti egzistuojančias sistemas, ir jų taikymas bibliotekų informacinei sistemai. Tyrimo objektas – mokslo publikacijų, atitinkančių lituanistikos sampratą, bibliografinės duomenų bazės projektavimas ir kūrimas. Darbo tikslas – pagerinti lituanistikos sampratą atitinkančių mokslo publikacijų vertinimo bei sklaidos galimybes, automatizuoti šių publikacijų pateikimo, ekspertavimo bei sklaidos procesus. / International social and humanitarian science and abstract bibliographic databases includes the most important and most significant of these documents in scientific fields. Databases developed thematically (eg, MLA International Bibliography, Sociological Abstracts CSA) and / or regional basis (eg, British Humanities Index). Search of international databases are a great tool for quickly and efficiently find information about the world of the studies performed and published scholarly works in the social and humanitarian sciences publications. Lithuanian academic journals and research publications in international databases is increasing in recent years, but in Lithuania the tests and researchers work to develop international databases is only fragmentary. International social and humanitarian sciences databases of lithuanistic ensure the development of Lithuanian scientists work visibility in national and international level and at the same scientists laid down in recognition of excellence. This database should be based on best international social and humanitarian experience of databases.

This thesis reports an investigation on the feasibility study of a searching mechanism using an APP suitable for an on-line bibliographic retrieval, operation, especially for retrospective searches. From the study of the searching methods used in the conventional systems it is seen that elaborate file- and data- structures are introduced to improve the response time of the system. These consequently lead to software and hardware redundancies. To mask these complexities of the system an expensive computer with higher capabilities and more powerful instruction set is commonly used. Thus the service of the systen becomes cost-ineffective. On the other hand the primitive operations of a searching mechanism, such as, association, domain selection, intersection and unions, are the intrinsic features of an associative parallel processor. Therefore it is important to establish the feasibility of an APP as a cost-effective searching mechanise. In this thesis a searching mechanism using an 'ON-THE-FLY' searching technique has been proposed. The parallel search unit uses a Byte-oriented VRL-APP for efficient character string processing. At the time of undertaking this work the specification for neither the retrieval systems nor the BO-VRL APP's were well established; hence a two-phase investigation was originated. In the Phase I of the work a bottom up approach was adopted to derive a formal and precise specification for the BO-VRL-APP. During the Phase II of the work a top-down approach was opted for the implementation of the searching mechanism. An experimental research vehicle has been developed to establish the feasibility of an APP as a cost-effective searching mechanism. Although rigorous proof of the feasibility has not been obtained, the thesis establishes that the APP is well suited for on-line bibligraphic information retrieval operations where substring searches including boolean selection and threshold weights are efficiently supported.

The aim of the research was to investigate the formation of the information management discipline, propose a framework by which it is presently understood, and test that framework within a particular area of application, namely the provision of scientific and technological information (STI) services. The work is presented as a PhD by Publication which comprises a narrative that encompasses the series of published papers, and includes excerpts from the book written to illustrate the province of the discipline. In thee book the disciplinary context is detailed and exemplified based upon information management domains. The book consolidates information management principles within a framework defined by these operational, analytical and administrative domains. It was created by a redaction of prior epistemological proposals; an analysis of the understanding of practice that has been shaped by professional, institutional and information science influences; and demonstration of practice within the domain framework. The disciplinary framework was then used in a series of STI case studies where it was found to provide an effective description of information management. Together, the book and subsequent case studies provided illustration of the principles utilised in information management and the way that they are practiced within different domains, along with an explanation of the manner in which the information management discipline has been formed. These should assist with direction of future research and scholarship particularly with respect to factors relevant to information services and indicators for their successful application in future. It is anticipated that this generalised description of the practices across the range of interpretations of information management should enable practicing information professionals to appreciate the relationship of their own work to disciplines that are converging towards similar purpose, such as through a clearer indication of the extent to which technical and management standards may be applied, and performance analysis undertaken. Complementary outcomes that were achieved during the course of the work were: a comparative analysis of thesauri in the information field which shows that in this field, the ways that information professionals represent themselves remains unreconciled; an historical examination of Australian STI services that provides pointers to their effective continuation; and a reconsideration of the relationship between librarianship and information management. The work is presented as a compilation of papers that comprise firstly extracts from the book to exemplify its consolidation of information management principles, then a number of published and submitted papers that examine how principles have been applied in practice. This is in the context of six case studies of Australian STI services including interviews with creators and developers, and analysis of historical information.
