Since classical antiquity, the public library has been the institution that helps people to know their history and face the changes that society increasingly demands. Similarly, school libraries are piloting the learning of children; in them, manage to have their first contact with books, his first great travel stories with dinosaurs, robots, fiction, among others through the stories, legends and knowledge games. School libraries contribute to strengthening reading habits from the earliest years of life.In conducting the research, developed an assessment of the current situation of the two libraries under study, based on the following variables: services, human resources, budget, infrastructure, children's collection, furniture, electronic equipment and audiovisual, recreational interests, needs of information, socio-cultural characteristics and availability. This was achieved through the collection of information externada by children of preschool and junior, mothers or guardians and teachers of the Education Unit of Four Queens and in charge of the School Library Education Unit Four Queens (BEUPCR) and J. Francisco Public Library Orlich (BPFJO).According to the diagnosis and analysis of information, it is shown that the aspects related to personnel, electronic equipment and resources are limited, in addition, there were deficiencies in infrastructure BEUPCR.

The Library of the Institute of Alajuela made an induction experience and training of users and ventured into the information literacy and engaged in the work of the teaching-learning as an integral part of the curriculum. The actions of the library in developing search strategies, location, selection and use of information brought inthe health service, changes to the role of the library, the librarian, the book and the information in the educational environment.By sharing this experience is intended to provide information that can motivate staff of educational institutions that wish toenter the field of information literacy as a strategy to support the development oflifelong independent learning skills and meaningful learning. Currently, the library should be a proactive part in the education of students but also teachers, administrative and family.This will result in a benefit to Costa Rica: the development of youth and their proper integration into the workplace.

Purpose – The purpose of this paper is to propose a theoretical framework, based on contemporary philosophical aesthetics, from which principled assessments of the aesthetic value of information organization frameworks may be conducted.Design/methodology/approach – This paper identifies appropriate discourses within the field of philosophical aesthetics, constructs from them a framework for assessing aesthetic properties of information organization frameworks. This framework is then applied in two case studies examining the Library of Congress Subject Headings (LCSH), and Sexual Nomenclature: A Thesaurus. Findings – In both information organization frameworks studied, the aesthetic analysis was useful in identifying judgments of the frameworks as aesthetic judgments, in promoting discovery of further areas of aesthetic judgments, and in prompting reflection on the nature of these aesthetic judgments. Research limitations/implications – This study provides proof-of-concept for the aesthetic evaluation of information organization frameworks. Areas of future research are identified as the role of cultural relativism in such aesthetic evaluation and identification of appropriate aesthetic properties of information organization frameworks.Practical implications – By identifying a subset of judgments of information organization frameworks as aesthetic judgments, aesthetic evaluation of such frameworks can be made explicit and principled. Aesthetic judgments can be separated from questions of economic feasibility, functional requirements, and user-orientation. Design and maintenance of information organization frameworks can be based on these principles.Originality/value – This study introduces a new evaluative axis for information organization frameworks based on philosophical aesthetics. By improving the evaluation of such novel frameworks, design and maintenance can be guided by these principles.Keywords Evaluation, Research methods, Analysis, Bibliographic systems, Indexes, Retrieval languages

Over the last decade, the rapid growth and adoption of the World Wide Web has further exacerbated user needs for e±cient mechanisms for information and knowledge location, selection, and retrieval. How to gather useful and meaningful information from the Web becomes challenging to users. The capture of user information needs is key to delivering users' desired information, and user pro¯les can help to capture information needs. However, e®ectively acquiring user pro¯les is di±cult. It is argued that if user background knowledge can be speci¯ed by ontolo- gies, more accurate user pro¯les can be acquired and thus information needs can be captured e®ectively. Web users implicitly possess concept models that are obtained from their experience and education, and use the concept models in information gathering. Prior to this work, much research has attempted to use ontologies to specify user background knowledge and user concept models. However, these works have a drawback in that they cannot move beyond the subsumption of super - and sub-class structure to emphasising the speci¯c se- mantic relations in a single computational model. This has also been a challenge for years in the knowledge engineering community. Thus, using ontologies to represent user concept models and to acquire user pro¯les remains an unsolved problem in personalised Web information gathering and knowledge engineering. In this thesis, an ontology learning and mining model is proposed to acquire user pro¯les for personalised Web information gathering. The proposed compu- tational model emphasises the speci¯c is-a and part-of semantic relations in one computational model. The world knowledge and users' Local Instance Reposito- ries are used to attempt to discover and specify user background knowledge. From a world knowledge base, personalised ontologies are constructed by adopting au- tomatic or semi-automatic techniques to extract user interest concepts, focusing on user information needs. A multidimensional ontology mining method, Speci- ¯city and Exhaustivity, is also introduced in this thesis for analysing the user background knowledge discovered and speci¯ed in user personalised ontologies. The ontology learning and mining model is evaluated by comparing with human- based and state-of-the-art computational models in experiments, using a large, standard data set. The experimental results are promising for evaluation. The proposed ontology learning and mining model in this thesis helps to develop a better understanding of user pro¯le acquisition, thus providing better design of personalised Web information gathering systems. The contributions are increasingly signi¯cant, given both the rapid explosion of Web information in recent years and today's accessibility to the Internet and the full text world.

Over the last decade, the majority of existing search techniques is either keyword- based or category-based, resulting in unsatisfactory effectiveness. Meanwhile, studies have illustrated that more than 80% of users preferred personalized search results. As a result, many studies paid a great deal of efforts (referred to as col- laborative filtering) investigating on personalized notions for enhancing retrieval performance. One of the fundamental yet most challenging steps is to capture precise user information needs. Most Web users are inexperienced or lack the capability to express their needs properly, whereas the existent retrieval systems are highly sensitive to vocabulary. Researchers have increasingly proposed the utilization of ontology-based tech- niques to improve current mining approaches. The related techniques are not only able to refine search intentions among specific generic domains, but also to access new knowledge by tracking semantic relations. In recent years, some researchers have attempted to build ontological user profiles according to discovered user background knowledge. The knowledge is considered to be both global and lo- cal analyses, which aim to produce tailored ontologies by a group of concepts. However, a key problem here that has not been addressed is: how to accurately match diverse local information to universal global knowledge. This research conducts a theoretical study on the use of personalized ontolo- gies to enhance text mining performance. The objective is to understand user information needs by a \bag-of-concepts" rather than \words". The concepts are gathered from a general world knowledge base named the Library of Congress Subject Headings. To return desirable search results, a novel ontology-based mining approach is introduced to discover accurate search intentions and learn personalized ontologies as user profiles. The approach can not only pinpoint users' individual intentions in a rough hierarchical structure, but can also in- terpret their needs by a set of acknowledged concepts. Along with global and local analyses, another solid concept matching approach is carried out to address about the mismatch between local information and world knowledge. Relevance features produced by the Relevance Feature Discovery model, are determined as representatives of local information. These features have been proven as the best alternative for user queries to avoid ambiguity and consistently outperform the features extracted by other filtering models. The two attempt-to-proposed ap- proaches are both evaluated by a scientific evaluation with the standard Reuters Corpus Volume 1 testing set. A comprehensive comparison is made with a num- ber of the state-of-the art baseline models, including TF-IDF, Rocchio, Okapi BM25, the deploying Pattern Taxonomy Model, and an ontology-based model. The gathered results indicate that the top precision can be improved remarkably with the proposed ontology mining approach, where the matching approach is successful and achieves significant improvements in most information filtering measurements. This research contributes to the fields of ontological filtering, user profiling, and knowledge representation. The related outputs are critical when systems are expected to return proper mining results and provide personalized services. The scientific findings have the potential to facilitate the design of advanced preference mining models, where impact on people's daily lives.

Hard-line anti-communists in the United States recognised the potential for the Soviet invasion of Afghanistan in 1979 to embroil their super-power rival in a ‘Vietnam-like quagmire.’ Their covert operation to arm the mujahedeen is well documented. This dissertation argues that propaganda and public diplomacy were powerful and essential instruments of this campaign. It examines the protagonists of this strategy, their policies, initiatives and programmes offering a comprehensive analysis heretofore absent. It stretches from the dying days of the Carter administration when Zbigniew Brzezinski saw the ‘opportunity’ presented by the invasion to the Soviet’s withdrawal in 1989. The aim of these information strategies was to damage Soviet credibility and enhance that of the US, considered under threat from growing ‘moral equivalence’ amongst international publics. The conflict could help the US regain strategic advantage in South Asia undermined by the ‘loss’ of Iran. The Reagan administration used it to justify the projection of US military might that it believed was eviscerated under Carter and emasculated by the lingering legacy of Vietnam. The research engages with source material from the Reagan Presidential Library, the United States Information Agency archives and the Library of Congress as well as a number of online archives. The material is multi-archival and multi-media including documentaries, booklets, press conferences, summit programmes and news-clips as well as national security policy documents and contemporaneous media commentary. It concludes that propaganda and public diplomacy were integral to the Reagan administration and other mujahedeen supporters’ determination to challenge the USSR. It finds that the conflict was used to justify military rearmament, further strategic aims and reassert US power. These Cold War machinations had a considerable impact on the course of the conflict and undermined efforts at resolution and reconciliation with profound implications for the future stability of Afghanistan and the world.

This thesis is an investigation into the US response to the Khmer Rouge regime in Cambodia between 1974 and 1981. It argues that the US experience in the Vietnam War acted as a causal factor in the formulation of its Cambodian policy during the presidencies of Gerald Ford and Jimmy Carter. From taking power in April 1975 to their removal by the Vietnamese in January 1979, the Khmer Rouge initiated a revolution unrivalled in the 20th Century for its brutality and for the total eradication of modern society. This thesis demonstrates that the Ford administration viewed Cambodia only as it pertained to their strategy in Vietnam and, following US disengagement from Indochina all but ignored the atrocities occurring there as they instead pursued informal relations with the Khmer Rouge as a means of punishing the Vietnamese. The Carter administration formulated a foreign policy based on human rights yet failed to adequately address the genocide that occurred in Cambodia due to its temporal and regional proximity to Vietnam. Instead, this collective reluctance to reengage with the region and the resulting anti-Vietnamese attitude reinforced Brzezinski’s broader global strategy that allied the US with China in support of an independent Cambodia to further isolate Hanoi. Thus this thesis argues that the distorting impact of the Vietnam War, as well as global Cold War calculations, undermined any appreciation of the Cambodian conflict and caused both administrations to pursue policies in Cambodia that ultimately supported the Khmer Rouge regime. This project incorporates declassified material from the Ford and Carter Presidential Libraries, supplemented by the material from the National Archives and Library of Congress, and relevant newspapers and periodicals. It demonstrates that the limitations placed upon US foreign policy by their experience in the Vietnam War may be used to reveal unexplored elements in US-Cambodian relations.
