    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Development and deployment of document management technology into Rover : executive summary

    Get PDF
    Document Management is a technology that allows the input, storage, management and control of an image under the supervision of a computer based system. A document may be an electronically scanned image of a hard copy document or an electronic image such as a word-processed file, sound file, video file, or graphics file. Once the document has entered the system, a full history of that document is maintained throughout its lifecycle. The author was responsible for the introduction, development and deployment of Document Management technology into Rover Group. The task given to the author was to implement Document Management technology purely as a repository and distribution management system for engineering drawings. However, by adopting an innovative approach to the application of Document Management technology, substantial benefits were realised. As the author became more conversant with Document Management technology, greater benefits became apparent. Following detailed analysis of Rover's existing `Engineering drawing release process' the author re-engineered the process to allow electronic paperless release of all engineering drawings. This re-engineering provided Rover with substantial tangible and intangible benefits including cost reduction, improved quality of data, reduced `time to market', improved access, improved cycle time and reductions in manual labour. Three projects detailed in the portfolio demonstrate how this technology was applied to existing systems and processes. In particular, the `Hams Hall' project clearly demonstrates innovation in the way in which the author used the technology to manage working practices and data structure for a multi-disciplined team located in different countries. With changes implemented by the author, Rover now hold substantially more digital data than before the implementation of Document Management technology. Following research work by the author into both the types of data held and the use to which that data was put, the legality of that data came into question. This prompted a detailed analysis of the legal requirements of digitally stored data that allowed the author to advise Rover Group of their current status and make recommendations to ensure legal admissibility. The work reported shows how a combination of technical expertise and an appreciation of business issues and drivers, is crucial to the effective and successful implementations of information systems. Other organisations have shown considerable interest in the improved Document Management technology enabled business processes, developed by the author

    Document expansion for image retrieval

    Successful information retrieval requires effective matching between the user's search request and the contents of relevant documents. Often the request entered by a user may not use the same topic relevant terms as the authors' of the documents. One potential approach to address problems of query-document term mismatch is document expansion to include additional topically relevant indexing terms in a document which may encourage its retrieval when relevant to queries which do not match its original contents well. We propose and evaluate a new document expansion method using external resources. While results of previous research have been inconclusive in determining the impact of document expansion on retrieval effectiveness, our method is shown to work effectively for text-based image retrieval of short image annotation documents. Our approach uses the Okapi query expansion algorithm as a method for document expansion. We further show improved performance can be achieved by using a \document reduction" approach to include only the significant terms in a document in the expansion process. Our experiments on the WikipediaMM task at ImageCLEF 2008 show an increase of 16.5% in mean average precision (MAP) compared to a variation of Okapi BM25 retrieval model. To compare document expansion with query expansion, we also test query expansion from an external resource which leads an improvement by 9.84% in MAP over our baseline. Our conclusion is that the document expansion with document reduction and in combination with query expansion produces the overall best retrieval results for shortlength document retrieval. For this image retrieval task, we also concluded that query expansion from external resource does not outperform the document expansion method

    Tilting at Windmills : BLDSC and the UK Higher Education Community

    Purpose - To provide an overview of, the relationship between the British Library and higher education libraries in the 1990s, with particular relation to document supply. It also goes on to explore current developments in scholarly communication. Design/methodology/approach - The author played a role in several of the events described and uses the available literature to enlarge on a personal view of that decade. Findings - The paper shows that the relationship was a strained one caused in part by a mismatch of resources, but is in any case dwarfed by the larger external forces and changing opportunities and technologies for scholarly communication. Originality/value - Provides a record of the period

    Tagging of Biomedical Articles on CiteULike: A Comparison of User, Author and Professional Indexing

    This paper examines the context of online indexing from the viewpoint of three different groups: users, authors, and professional indexers. User tags, author keywords and descriptors were collected from academic journal articles, which were both indexed in Pubmed and tagged on CiteULike, and analysed. Descriptive statistics, informetric measures, and thesaural term comparison shows that there are important differences in the use of keywords between the three groups in addition to similarities which can be used to enhance support for search and browse. While tags and author keywords were found that matched descriptors exactly, other terms which did not match but provided important expansion to the indexing lexicon were found. These additional terms could be used to enhance support for searching and browsing in article databases as well as to provide invaluable data for entry vocabulary and emergent terminology for regular updates to indexing systems. Additionally, the study suggests that tags support organisation by association to task, projects and subject while making important connections to traditional systems which classify into subject categories

    Enhancing Author Information for CERN Document Server: Creating an Author Collection and Using Author Disambiguation Methods

    No full text
    Authors are a substantial part of queries in digital libraries, where the results are reflecting the service quality and success. Ambiguous author names can confuse users and cause an inaccurate relation between authorships and individual researchers. Providing a set of disambiguated authors is challenging and related to data integration, since this is done in several ways and by different systems, both manually and automatically. Many disambiguation algorithms have been proposed in the literature, where the most solutions are solving the ambiguities by applying machine learning techniques. However, such problems cannot be solved with an accuracy of 100%. Our contributions to the CERN Document Server presented in this work consists of two parts: first, we create and deploy an author knowledge data base (collection) and second, we link authors of bibliographic records back to their authority records. For the latter, we use a library providing machine learning tools for clustering (where we use trained data from INSPIRE---a High-Energy Physics literature database developed at CERN) and construct an algorithm to build the relation, based on authority id and name matching. We could attribute 30% of 9 million authors to almost 9'500 individuals, which is also limited to our current author collection containing more than 41'000 records (and counting), based on people affiliated to the organization

    Preventing document leakage through active document

    Electronic documents inside any enterprise environment are assets that add to the enterprise’s capital in intellectual property such as design patents or customer information, securing, these assets is a priority requirement in any security system design. The security of these documents suffers when they have migrated outside the organization security system, as there is not always a way to extend the enterprise security policy to limit/prevent access to those assets. This paper presents the challenges faced when preventing document leakage. We propose active document as a measure to control/limit access when electronic document are outside its domain

    Understanding why individuals might safeguard information or keep secrets in working documents such as medical records is essential for the development of good quality care, fostering an environment where both patients and staff feel secure to part with sensitive information, encouraging more honest and open communication as well as improved quality of care. This ongoing research aims to deepen comprehension of information behavior in clinical contexts, where the contemporary medical record, with its increasing properties such as open record access for patients, can be viewed as an entity that both listens and influences. This examination sheds light on the complex dynamics of truth within clinical environments, where patients and health care professionals, due to a continuously evolving document, might selectively disclose or withhold information, aiming to safeguard themselves. Fifteen informant interviews among Swedish clinicians in pediatric psychiatry concerning the impact of open record access reveal that the contemporary medical record takes on a form reminiscent of a malleable presence, embodying qualities of a sentient being within the treatment space. Findings in the study shed light on the intricate mechanisms through which the protection of both information, patient, and clinician, intertwine with the contemporary medical record as an entity of great agency
