1Nichols, D.M. ; Twidale, M.B.: Metrics for openness.
In: Journal of the Association for Information Science and Technology. 68(2017) no.4, S.1048-1060.
Abstract: The characterization of scholarly communication is dominated by citation-based measures. In this paper we propose several metrics to describe different facets of open access and open research. We discuss measures to represent the public availability of articles along with their archival location, licenses, access costs, and supporting information. Calculations illustrating these new metrics are presented using the authors' publications. We argue that explicit measurement of openness is necessary for a holistic description of research outputs.

In: Cataloging and classification quarterly. 47(2009) nos.3/4, S.xx-xx.
Abstract: Current institutional repository software provides few tools to help metadata librarians understand and analyse their collections. In this paper, we compare and contrast metadata analysis tools that were developed simultaneously, but independently, at two New Zealand institutions during a period of national investment in research repositories: the Metadata Analysis Tool (MAT) at The University of Waikato, and the Kiwi Research Information Service (KRIS) at the National Library of New Zealand. The tools have many similarities: they are convenient, online, on-demand services that harvest metadata using OAI-PMH, they were developed in response to feedback from repository administrators, and they both help pinpoint specific metadata errors as well as generating summary statistics. They also have significant differences: one is a dedicated tool while the other is part of a wider access tool; one gives a holistic view of the metadata while the other looks for specific problems; one seeks patterns in the data values while the other checks that those values conform to metadata standards. Both tools work in a complementary manner to existing web-based administration tools. We have observed that discovery and correction of metadata errors can be quickly achieved by switching web browser views from the analysis tool to the repository interface, and back. We summarise the findings from both tools' deployment into a checklist of requirements for metadata analysis tools.

4Twidale, M.B. ; Nichols, D.M.: Collaborative information retrieval.
In: Encyclopedia of library and information sciences. 3rd ed. Ed.: M.J. Bates. London : Taylor & Francis, 2009. S.xx-xx.
Abstract: Collaborative information retrieval (CIR) encompasses the many varied social approaches to information seeking. Although some information retrieval systems have given an impression of individual access to resources, there is a growing realization that much information work is fundamentally collaborative in nature. We highlight key points in the recent history of CIR, particularly the difference between explicit and implicit collaboration.

In: Journal of the American Society for Information Science and Technology. 59(2008) no.6, S.983-1001.
Abstract: The classic problem within the information quality (IQ) research and practice community has been the problem of defining IQ. It has been found repeatedly that IQ is context sensitive and cannot be described, measured, and assured with a single model. There is a need for empirical case studies of IQ work in different systems to develop a systematic knowledge that can then inform and guide the construction of context-specific IQ models. This article analyzes the organization of IQ assurance work in a large-scale, open, collaborative encyclopedia - Wikipedia. What is special about Wikipedia as a resource is that the quality discussions and processes are strongly connected to the data itself and are accessible to the general public. This openness makes it particularly easy for researchers to study a particular kind of collaborative work that is highly distributed and that has a particularly substantial focus, not just on error detection but also on error correction. We believe that the study of those evolving debates and processes and of the IQ assurance model as a whole has useful implications for the improvement of quality in other more conventional databases.

In: Information processing and management. 44(2008) no.2, S.558-580.
Abstract: Information provision via digital libraries often separates the writing process from that of information searching. In this paper we investigate the potential of a tighter integration between searching for information in digital libraries and using those results in academic writing. We consider whether it may sometimes be advantageous to encourage searching while writing instead of the more conventional approach of searching first and then writing. The provision of ambient search is explored, taking the user's ongoing writing as a source for the generation of search terms used to provide possibly useful results. A rapid prototyping approach exploiting web services was used as a way to explore the design space and to have working demonstrations that can provoke reactions, design suggestions and discussions about desirable functionalities and interfaces. This design process and some preliminary user studies are described. The results of these studies lead to a consideration of issues arising in exploring this design space, including handling irrelevant results and the particular challenges of evaluation.

7Stvilia, B. ; Gasser, L. ; Twidale, M.B. ; Smith, L.C.: ¬A framework for information quality assessment.
In: Journal of the American Society for Information Science and Technology. 58(2007) no.12, S.1720-1733.
Abstract: One cannot manage information quality (IQ) without first being able to measure it meaningfully and establishing a causal connection between the source of IQ change, the IQ problem types, the types of activities affected, and their implications. In this article we propose a general IQ assessment framework. In contrast to context-specific IQ assessment models, which usually focus on a few variables determined by local needs, our framework consists of comprehensive typologies of IQ problems, related activities, and a taxonomy of IQ dimensions organized in a systematic way based on sound theories and practices. The framework can be used as a knowledge resource and as a guide for developing IQ measurement models for many different settings. The framework was validated and refined by developing specific IQ measurement models for two large-scale collections of two large classes of information objects: Simple Dublin Core records and online encyclopedia articles.

In: Journal of the American Society for Information Science. 51(2000) no.7, S.666-682.
Abstract: This paper describes ethnomethodologically informed ethnography (EM) as a methodology for information science research, illustrating the approach with the results of a study in a university library. We elucidate major differences between the practical orientation of EM and theoretical orientation of other ethnographic approaches in information science research. We address ways in which EM may be used to inform systems design and consider the issues that arise in coordinating the results of this research with the needs of information systems designers. We outline out approach to the 'ethnographically informaed' development of information systems in addressing some of the major problems of interdisciplinary work between system designers and EM researchers

In: Information processing and management. 33(1997) no.6, S.761-783.
Abstract: Collaboration is an important aspect of searching online information retrieval systems that requires explicit computerized support. Surveys a number of systems offering varied approaches to supporting collaboration and applies a strucutre for analysing the various aspect of collaboration. The dominant form of collaboration in digital libraries is likely to be remote and asynchronous. Collaborative work in the digital library requires that both the search product and the search process can be captured and communicated. Introduces the ARIADNE system as an example of computerized support for collaboration between bowsers
11Twidale, M.B. ; Nichols, D.M.: Collaborative browsing and visualization of the search process.
In: Aslib proceedings. 48(1996) nos.7/8, S.177-182.
Abstract: We describe how to support the process of collaborative browsing and how to integrate support for the social aspects of information searching activities into information systems and particularly their interfaces. The use of library resources is often stereotyped as a solitary activity. However, informal observations indicate significant collaboration between users despite the fact that existing systems fail to support this. We describe the Ariadne system which does attempt to support collaboration by providing a visualization of the search process. Storage of search histories as digital object allows them to be manipulated and communicated. An explicit representation of a search history supports discussion of search strategies and concepts by explicit pointing to prior activities even when one of the participants may be a novice lacking the appropriate vocabulary. Several different types of activity, synchronous and asynchronous, remote and co-located, can be supported by search process re-use. We outline some of the issues of privacy concerned with the storage of users' searches
