Over the past two decades (1980s and 1990s), changes in environmental factors demanded that higher education institutions should be managed more efficiently. It is necessary for library administrators to evaluate their organisational structures in order to meet their customers' rising expectation and parent institutions' vision, mission, and strategy for future development. The purpose of this study was to examine the extent oflibrary reorganisation within the UK and Taiwan universities, and the principal differences and similarities on organisational structure changes between 1985 and 2001. This study was a population study. This study was composed of two surveys (the initial survey and the follow-up survey) in the two countries. Quantitative data was gathered though a questionnaire. The researcher investigated general aspects of library reorganisation, then focused specific on eight research problems and conducted comparison between the UK and Taiwan. Thirteen hypotheses centered on the issues concerning organisational structure changes were tested. Of the thirteen hypotheses, some were supported by the study and others were not. Comparisons were made among organisational charts during this IS-year period. The main findings are: (1) The extent of library reorganisation for the two countries was high over the IS-year period (1985-2001). However, there had been an overall decline during the follow-up survey period. If the non-respondents represented a biassed set (they all had not conducted organisational structure change), then the extent of change in the two countries was actually not so high. The plans of organisational change will continue with 30% respondents from UK and 24% from Taiwan in the follow-up survey were considering the possibility. (2) There was no significant relationship between the extent of the library reorganisation and the selected background of libraries studied. (3) Of the environmental factors responsible for organisational structure changes, Service reasons and management reasons played the top two major roles. Economic and technological influences on organisational change declined over the survey time. 'Changes in higher Education', 'the development of digitized collection/digital library', 'change in human expectations', and 'changes in scholarly publishing/communication' became the important reasons for changes in the follow-up survey period. (4) Most of the libraries conducted internally reorganisation rather than externally. The top two methods adopted in internal reorganisation were: 'creating new functions/departments/units', and 'combination of functions'. Convergence activities were only reported by several responding libraries, the results showed that the extent of convergence activities seemed increased with time. The major reasons for the convergence were: shared vision; to pursue a more effective administration; to cooperate in supporting teaching, research, and learning; overlapping missions and strategies; exchanges of specialization between organisations; more economic administration; to cooperate in development of digital resources and digital collection; sharing of staff, facilities, and equipment. (5) After reorganisation, most university libraries in the UK adopted hierarchical structure and based on a combined functional/subject-based pattern. Team-based structure was the second favorite. Almost all respondents' libraries in Taiwan preferred a hierarchical structure and based on a functional pattern, however, 'teamwork' concept was adopted by some libraries. (6) The new organisations mostly emphasized user services, integration of the management of varied resources in libraries, and technological support. (7) The management levels of libraries in the UK tended to be flatter after reorganisation. However, most of the libraries in Taiwan retained the same management level after reorganisation. (8) The title of library managers within UK universities became more versatile after reorganisation. However, most of the library managers in Taiwan retained the same title even after reorganisation. (9) The considered important challenges of organisational change were: 'the parent institutional climate'; 'managerial support within and outside the library'; 'the climate of the libraries'; 'the staff strengths and weaknesses'; 'staff attitudes towards change'; 'the attitude of library directors'. (10) The results of library reorganisation have been mostly positive, and have provided lessons in organisational change from which other libraries may benefit.

Examines the historiographical and practical problems of using newspapers in historical research. Studies the methods of different types of professional and non-professional historians, to evaluate the value of newspapers as historical documents and the problems particular to them. Examines the difficulties associated with newspapers in library collections from both the perspectives of newspaper users and custodians. Seeks to provide recommendations for both groups to facilitate the use of newspapers. The research adopted essentially qualitative methods. Using questionnaires and interviews, the opinions and experiences of historians in Wales were studied. Case studies of newspaper collections in Wales were undertaken to examine current policies and strategies at a local level. The research was also undertaken with collaboration from the British Library Newspaper Library and with specific reference to the work of the NEWSPLAN project. Concludes that newspapers are an important source for all manner of historical enquiries, but that historians often require further guidance in order to search, use and evaluate them. Different patterns of use were observed among different types of historians. Also suggests that newspapers are unlike other historical documents, because of their nature and role in society. Specific techniques are provided to assist the historian using newspapers. The use of newspapers is also shaped by the policies and strategies of both local and national newspaper collections. Thus, guidelines and recommendations are provided to assist these organisations. Further work is urged, to understand the needs of historians and the specific problems that newspapers present, following the five million pound Heritage Lottery Fund Award for the NEWSPLAN project in March 1999.

Classification is a fundamental tool in the organisation of any library collection for effective information retrieval. Several classifications exist, yet the pioneering Dewey Decimal Classification (DDC) still constitutes the most widely used scheme and international de facto standard. Although once used for the dual purpose of physical organisation and subject retrieval in the printed library catalogue, library classification is now relegated to a singular role of shelf location. Numerous studies have highlighted the problem of subject access in library online public access catalogues (OPACs). The library OPAC has changed relatively little since its inception, designed to find what is already known, not discover and explore. This research aims to enhance OPAC subject searching by deriving facets of the DDC and populating these with a library collection for display at a View-based searching OPAC interface. A novel method is devised that enables the automatic deconstruction of complex DDC notations into their component facets. Identifying facets based upon embedded notational components reveals alternative, multidimensional subject arrangements of a library collection and resolves the problem of disciplinary scatter. The extent to which the derived facets enhance users' subject searching perceptions and activities at the OPAC interface is evaluated in a small-scale usability study. The results demonstrate the successful derivation of four fundamental facets (Reference Type, Person Type, Time and Geographic Place). Such facet derivation and deconstruction of Dewey notations is recognised as a complex process, owing to the lack of a uniform notation, notational re-use and the need for distinct facet indicators to delineate facet boundaries. The results of the preliminary usability study indicate that users are receptive to facet-based searching and that the View-based searching system performs equally as well as a current form fill-in interface and, in some cases, provides enhanced benefits. It is concluded that further exploration of facet-based searching is clearly warranted and suggestions for future research are made.

The emergence of third-generation, technology-based public bikeshare schemes offers new opportunities for researching cycling behaviour. In this study, data from one such scheme, the London Cycle Hire Scheme (LCHS), are analysed. Algorithms are developed for summarising and labelling cyclists’ usage behaviours and tailored visual analysis applications are designed for exploring their spatiotemporal context. Many of the research findings provide support to existing literature, particularly around gendered cycling behaviour. As well as making more discretionary journeys, women appear to preferentially select parts of London associated with greater levels of safety; and this is true even after controlling for geodemographic differences and levels of LCHS cycling experience. One hypothesis is that these differences represent diverging attitudes and perceptions. After developing a technique for identifying cyclists’ workplaces, these differences might also be explained by where cyclists need to travel for work and other facilities. An additional explanation is later offered that relates to the nature of cyclists’ estimated routes. The size and precision of the LCHS dataset allows under-explored aspects of behaviour to be investigated. Group cycling events – instances where two or more cyclists make journeys together in space and time – are labelled and analysed on a large scale. For certain types of cyclist, group cycling appears to encourage more extensive spatiotemporal cycling behaviour and there is some evidence to suggest that group cycling may help initiate scheme usage. The domain-specific findings, emerging research questions and also behavioural classifications are this study’s principal and unique contribution. A second contribution relates to the analysis approach. This is a data-driven study that takes a large dataset, measuring use of a relatively new cycle facility, and uses it to engage with research questions that are typically answered with very different datasets. There is some uncertainty around how discriminating and generalisable LCHS cycle behaviours may be and which variables, either directly measured or derived, might delineate those behaviours. Visual analysis techniques are shown to be effective in this more speculative research context: numerous behaviours are very quickly explored and understood. These techniques also enable a set of colleagues with relatively limited analysis experience, but substantial domain knowledge, to participate in the analysis and a general argument is made for their use in other, interdisciplinary analysis contexts.

National cultural heritage institutions are charged with representative preservation of their countries’ cultural materials and the ways their staff undertake preservation activities impact to whom and how these materials are representative. Music is hailed as an integral part of a nation’s cultural heritage, but while aspects of its preservation are individually understood, their combined treatment in cultural institutions — music curation — and its ability to alter concepts of national identity are not. Consequently, we must ask how does music curation influence notions of national identity? By answering this question, this thesis seeks to contribute to our understanding of the ways that national cultural heritage institutions shape and promote a sense of national community. Since its beginning in 1800, the Library of Congress in Washington, D.C. has adopted several roles: a congressional resource; a copyright repository; a research centre; a hub for and leader in the library community; and cultural heritage institution. These combine to make the Library of Congress the de facto national library of the United States. However, these roles are not inherently congruent and in some instances undermine each other. Additionally, music has not always been easily integrated into its mission and its collections. Functioning as a national library, the Library of Congress potentially performs significant roles in the preservation and presentation of music, activities that make it an appropriate case study for investigating how music curation affects notions of national identity. Therefore, this work is structured in the following way: first, it offers an historical overview of the Library of Congress’ three music related departments — the Music Division, the American Folklife Center and the Recorded Sound component of the Motion Picture, Broadcast and Recorded Sound Division — to illuminate political, cultural and aesthetic forces that shaped their developments and their approaches to music curation. Second, it presents Howard Becker’s art world as the analytical framework by which this thesis critically engages narrative and identity theories. Third, employing the Library of Congress as a case study, it then investigates eight music curation narratives and juxtaposes them against its image as a cultural heritage institution. Narratives, gathered during semi-structured interviews and presented as interpretive stories, provide a focused insight into the tensions between staff and institution as well as institution and projected notions of national identity. In the context of music curation, this thesis’ conclusions illustrate a gap between the Library of Congress’ iconic image and its actual image, one that is perpetuated by its focus on research.

The problem of determining whether a document is about a loosely defined topic is at the core of text Information Retrieval (IR). An automatic IR system should be able to determine if a document is likely to convey information on a topic. In most cases, it has to do it solely based on measure- ments of the use of terms in the document (lexical measurements). In this work a novel scheme for measuring and representing lexical information from text documents is proposed. This scheme is inspired by the concept of ideal measurement as is described by Quantum Theory (QT). We apply it to Information Retrieval through formal analogies between text processing and physical measurements. The main contribution of this work is the development of a complete mathematical scheme to describe lexical measurements. These measurements encompass current ways of repre- senting text, but also completely new representation schemes for it. For example, this quantum-like representation includes logical features such as non-Boolean behaviour that has been suggested to be a fundamental issue when extracting information from natural language text. This scheme also provides a formal unification of logical, probabilistic and geometric approaches to the IR problem. From the concepts and structures in this scheme of lexical measurement, and using the principle of uncertain conditional, an “Aboutness Witness” is defined as a transformation that can detect docu- ments that are relevant to a query. Mathematical properties of the Aboutness Witness are described in detail and related to other concepts from Information Retrieval. A practical application of this concept is also developed for ad hoc retrieval tasks, and is evaluated with standard collections. Even though the introduction of the model instantiated here does not lead to substantial perfor- mance improvements, it is shown how it can be extended and improved, as well as how it can generate a whole range of radically new models and methodologies. This work opens a number of research possibilities both theoretical and experimental, like new representations for documents in Hilbert spaces or other forms, methodologies for term weighting to be used either within the proposed framework or independently, ways to extend existing methodologies, and a new range of operator-based methods for several tasks in IR.

Searching for information is a recurring problem that almost everyone has faced at some point. Being in a library looking for a book, searching through newspapers and magazines for an old article or searching through emails for an old conversation with a colleague are some examples of the searching activity. These are some of the many situations where someone; the “user”; has some vague idea of the information he is looking for; an “information need”; and is searching through a large number of documents, emails or articles; “information items”; to find the most “relevant” item for his purpose. In this thesis we study the problem of retrieving images from large image archives. We consider two different approaches for image retrieval. The first approach is content based image retrieval where the user is searching images using a query image. The second approach is semantic retrieval where the users expresses his query using keywords. We proposed a unified framework to treat both approaches using generative probabilistic models in order to rank and classify images with respect to user queries. The methodology presented in this Thesis is evaluated on a real image collection and compared against state of the art methods.

Music collections available to listeners have grown at a dramatic pace, now spanning tens of millions of tracks. Interacting with a music retrieval system can thus be overwhelming, with users offered ‘too-much-choice’. The level of engagement required for such retrieval interactions can be inappropriate, such as in mobile or multitasking contexts. Music recommender systems are widely employed to address this issue, however tend toward the opposite extreme of disempowering users and suffer from issues of subjectivity and confounds, such as the equalisation of tracks. This challenge and the styles of retrieval interaction involved are characterised in terms of user engagement in music retrieval, and the relationships between existing conceptualisations of user engagement is explored. Using listening histories and work from music psychology, a set of engagement-stratified profiles of listening behaviour are developed. A dataset comprising the playlists of thousands of users is used to contribute a user-centric approach to feature selection. The challenge of designing music retrieval for different levels of user engagement is first explored with a proof of concept, low engagement music retrieval system enabling users to casually retrieve music by tapping its rhythm as a query. The design methodology is then generalised with an engagement-dependent system, allowing users to denote their level of engagement and thus the specificity of their music queries. The engagement-dependent retrieval interaction is then explored as a component in a commercial music system. This thesis contributes the engagement-stratified profiles and metrics of listening behaviour, a corresponding design methodology for interaction, and presents a set of research and commercial applications for music retrieval.

This research examines the decision-making process of computer users with reference to deletion and preservation of digital objects. Of specific interest to this research is whether people provide different reasons for deleting or preserving various types of digital object dependant upon whether they are making such decisions at home or at work, whether such decisions are to any extent culturally determined, and whether they consider others in the course of making such decisions. This study considers the sociological implications of such decisions within organisations, and various psychological errors to be expected when such decisions are made. It analyses the reasons given for these decisions, within the contexts of home and work computing. It quantifies the frequency with which these activities are undertaken, the locations in which such objects are stored, and what aids the user in making such decisions. This research concludes that, while computer users generally desire their digital objects to be organised, they are not provided with adequate support from their computer systems in the decision to delete or preserve digital objects. It also concludes that such decisions are made without taking advantage of metadata, and these decisions are made for the same reasons both at home and at work: there is no discernible difference between the two contexts in terms of reasons given for such decisions. This study finds no correlation between subjects' culture and reasons given for deletion / preservation decisions, nor does it find any correlation between age and such reasons. This study further finds that users are generally averse to conforming to records management policies within the organisation. For archivists and records managers, this research will be of particular interest in its consideration of the usage of and attitudes towards records management systems. Specifically, in organisations possessing formal records management systems, this research investigates the frequency with which individuals violate records management procedures and why they consider such violations to be necessary or desirable. This research also argues towards a more proceduralised decision-making process on the part of the ordinary user and a deeper integration between records management systems and computer operating systems. Designers of formal information systems should consider this research for its implications regarding the way in which decisions are affected by the context in which those decisions are made. Information systems design may be best suited to understanding---and ameliorating---certain types of cognitive error such that users are enabled to make better deletion and preservation decisions. User interface designers are uniquely positioned to address certain cognitive errors simply by changing how information is presented; this research provides insight into just what those errors are and offers suggestions towards addressing them. For sociologists concerned with institutional memory, this research should be of interest because the deletion and preservation decisions of members of an organisation are those which shape the collection of digital artefacts available for study. Understanding the reasons for these decisions is likely to inform what interpretations can be drawn from the study of such collections. Also of interest to sociologists will be the variety of reasons given for deletion or preservation, as those reasons and decisions are what shape, to some extent, institutional memory.
