Thông tin về tạp chí
The journal publishes research papers with novel methods or results of wide significance, in all the information-related disciplines. Critical and scholarly reviews are welcome, as are reviews of the evidence base for professional practice, and shorter speculative articles. We particularly welcome submissions exploring topics where concepts and models in the library and information sciences overlap with those in cognate disciplines: these disciplines include, but are not limited to, psychology and cognitive science, the physical sciences, communication and media studies, museum studies, computer science, sociology and publishing. JDoc provides a link between research, scholarship and reflective professional practice. We also welcome contributions in the 'Speculation in Documentation' category.

THE DISTRIBUTION OF INDEXING DEPTH IN DOCUMENTATION SYSTEMS Most documentation systems allocate a variable number of descriptors to their documents. From a consideration of indexing as a stochastic process it is suggested that the distribution of indexing depth in such a system might represent samples of a (truncated) mixed Poisson process. Examination of five different systems showed that indexing depth does appear to be distributed in this manner, since a reasonable fit to negative binomial distributions can be made statistically. Factors in the art of indexing which influence the distribution are discussed. As a first approximation the distribution of indexing depth, i, of a system, or of any subset of descriptors in it, is simple Poisson, p(i) = e−m(mi/i!), where m is the average depth of indexing. The results contradict previous reports that a log‐normal distribution of indexing depth is to be expected.

THE CO‐ORDINATION OF ABSTRACTING SERVICES UNESCO is instructed by its constitution to ‘Maintain, increase and diffuse knowledge … by initiating methods of international co‐operation calculated to give the peoples of all countries access to the printed and published materials produced by any of them’. As one of the methods of carrying out this function the programmes of Unesco both for 1947 and 1948 specifically included plans to ‘facilitate the improvement of scientific documentation and abstracting’, and an Expert Committee on Scientific Abstracting was called together at Unesco House in Paris during the 7th, 8th, and 9th of April 1948, under the joint authority of the Libraries and Natural Science sections, for preliminary work in connexion with an international conference to be held at a later date.

Citing and referencing habits in medicine and social sciences journals in 2019 Purpose This article explores citing and referencing systems in social sciences and medicine articles from different theoretical and practical perspectives, considering bibliographic references as a facet of descriptive representation. Design/methodology/approach The analysis of citing and referencing elements (i.e. bibliographic references, mentions, quotations and respective in-text reference pointers) identified citing and referencing habits within disciplines under consideration and errors occurring over the long term as stated by previous studies now expanded. Future expected trends of information retrieval from bibliographic metadata was gathered by approaching these referencing elements from the Functional Requirements for Bibliographic Records (FRBR) entities concepts. Findings Reference styles do not fully accomplish with their role of guiding authors and publishers on providing concise and well-structured bibliographic metadata within bibliographic references. Trends on representative description revision suggest a predicted distancing on the ways information is approached by bibliographic references and bibliographic catalogs adopting FRBR concepts, including the description levels adopted by each of them under the perspective of the FRBR entities concept. Research limitations/implications This study was based on a subset of medicine and social sciences articles published in 2019 and, therefore, it may not be taken as a final and broad coverage. Future studies expanding these approaches to other disciplines and chronological periods are encouraged. Originality/value By approaching citing and referencing issues as descriptive representation's facets, findings on this study may encourage further studies that will support information science and computer science on providing tools to become bibliographic metadata description simpler, better structured and more efficient facing the revision of descriptive representation actually in progress.

THE NUMBER OF AUTHORS PER ARTICLE IN LIBRARY AND INFORMATION SCIENCE CAN OFTEN BE DESCRIBED BY A SIMPLE PROBABILITY DISTRIBUTION Ajiferuke showed that observed author distributions can best be described by a shifted inverse Gaussian‐Poisson distribution. Yet, in the framework of a model to explain observed fractional distributions of authors it is important to know whether a simple one‐parameter distribution such as a geometric or a truncated Poisson can adequately describe observed author distributions, at least in those fields where the single author is still dominant. In this article it is shown that for the field of information science this is indeed the case.

THE AMBIGUITY OF BRADFORD'S LAW Recent discussion of Bradford's law of scatter has been founded on two formulations that are not mathematically equivalent. A method of comparing the two formulations against empirical data is developed, and the results using four sets of existing data are discussed. The results show that one particular formulation is more consistent with the practical situation.

Discourse structure differences in lay and professional health communication Purpose In this paper the authors seek to compare lay (consumer) and professional (physician) discourse structures in answers to diabetes‐related questions in a public consumer health information website. Design/methodology/approach Ten consumer and ten physician question threads were aligned. They generated 26 consumer and ten physician answers, constituting a total dataset of 717 discourse units (in sentences or sentence fragments). The authors depart from previous LIS health information behaviour research by utilizing a computational linguistics‐based theoretical framework of rhetorical structure theory, which enables research at the pragmatics level of linguistics in terms of the goals and effects of human communication. Findings The authors reveal differences in discourse organization by identifying prevalent rhetorical relations in each type of discourse. Consumer answers included predominately (66 per cent) presentational rhetorical structure relations, those intended to motivate or otherwise help a user do something (e.g. motivation, concession, and enablement). Physician answers included mainly subject matter relations (64 per cent), intended to inform, or simply transfer information to a user (e.g. elaboration, condition, and interpretation). Research limitations/implications The findings suggest different communicative goals expressed in lay and professional health information sharing. Consumers appear to be more motivating, or activating, and more polite (linguistically) than physicians in how they share information with consumers online in similar topics in diabetes management. The authors consider whether one source of information encourages adherence to healthy behaviour more effectively than another. Originality/value Analysing discourse structure – using rhetorical structure theory – is a novel and promising approach in information behaviour research, and one that traverses the lexico‐semantic level of linguistic analysis towards pragmatics of language use.

Experimental components for the evaluation of interactive information retrieval systems This paper presents a set of basic components which constitutes the experimental setting intended for the evaluation of interactive information retrieval (IIR) systems, the aim of which is to facilitate evaluation of IIR systems in a way which is as close as possible to realistic IR processes. The experimental setting consists of three components: (1) the involvement of potential users as test persons; (2) the application of dynamic and individual information needs; and (3) the use of multidimensional and dynamic relevance judgements. Hidden under the information need component is the essential central sub‐component, the simulated work task situation, the tool that triggers the (simulated) dynamic information needs. This paper also reports on the empirical findings of the metaevaluation of the application of this sub‐component, the purpose of which is to discover whether the application of simulated work task situations to future evaluation of IIR systems can be recommended. Investigations are carried out to determine whether any search behavioural differences exist between test persons‘ treatment of their own real information needs versus simulated information needs. The hypothesis is that if no difference exists one can correctly substitute real information needs with simulated information needs through the application of simulated work task situations. The empirical results of the meta‐evaluation provide positive evidence for the application of simulated work task situations to the evaluation of IIR systems. The results also indicate that tailoring work task situations to the group of test persons is important in motivating them. Furthermore, the results of the evaluation show that different versions of semantic openness of the simulated situations make no difference to the test persons’ search treatment.

SCIENTISTS AND INFORMATION: II. PERSONAL FACTORS IN INFORMATION BEHAVIOUR The Kirton Adaption‐Innovation Inventory and the Learning Styles Questionnaire were used as part of a wider investigation, reported in an earlier paper, to explore the influence of personality, discipline and organisational structure on the information behaviour of biochemists, entomologists and statisticians working at an agricultural research station (n = 67). Results from the psychometric tests were assessed in terms of the groups obtained from a cluster analysis. Groups identified by the KAI as Innovators and by the LSQ as Activists sought information more widely, more enthusiastically and from more diverse sources than other groups. Groups identified as Adaptors by the KAI and Reflectors by the LSQ, were more controlled, methodical and systematic in their information behaviour.
