Abstract

Purpose

The object of this study is to develop methods for automatically annotating the argumentative role of sentences in scientific abstracts. Working from Medline abstracts, sentences were classified into four major argumentative roles: objective, method, result, and conclusion. The idea is that, if the role of each sentence can be marked up, then these metadata can be used during information retrieval to seek particular types of information such as novelty, conclusions, methodologies, aims/goals of a scientific piece of work.

Design/methodology/approach

Two approaches were tested: linguistic cues and positional heuristics. Linguistic cues are lexico‐syntactic patterns modelled as regular expressions implemented in a linguistic parser. Positional heuristics make use of the relative position of a sentence in the abstract to deduce its argumentative class.

Findings

The experiments showed that positional heuristics attained a much higher degree of accuracy on Medline abstracts with an F‐score of 64 per cent, whereas the linguistic cues only attained an F‐score of 12 per cent. This is mostly because sentences from different argumentative roles are not always announced by surface linguistic cues.

Research limitations/implications

A limitation to the study was the inability to test other methods to perform this task such as machine learning techniques which have been reported to perform better on Medline abstracts. Also, to compare the results of the study with earlier studies using Medline abstracts, the different argumentative roles present in Medline had to be mapped on to four major argumentative roles. This may have favourably biased the performance of the sentence classification by positional heuristics.

Originality/value

To the best of one's knowledge, this study presents the first instance of evaluating linguistic cues and positional heuristics on the same corpus.

Abstract

Purpose

To propose a comprehensive and semi‐automatic method for constructing or updating knowledge organization tools such as thesauri.

Design/methodology/approach

The paper proposes a comprehensive methodology for thesaurus construction and maintenance combining shallow NLP with a clustering algorithm and an information visualization interface. The resulting system TermWatch, extracts terms from a text collection, mines semantic relations between them using complementary linguistic approaches and clusters terms using these semantic relations. The clusters are mapped onto a 2D using an integrated visualization tool.

Findings

The clusters formed exhibit the different relations necessary to populate a thesaurus or ontology: synonymy, generic/specific and relatedness. The clusters represent, for a given term, its closest neighbours in terms of semantic relations.

Practical implications

This could change the way in which information professionals (librarians and documentalists) undertake knowledge organization tasks. TermWatch can be useful either as a starting point for grasping the conceptual organization of knowledge in a huge text collection without having to read the texts, then actually serving as a suggestive tool for populating different hierarchies of a thesaurus or an ontology because its clusters are based on semantic relations.

Originality/value

This lies in several points: combined use of linguistic relations with an adapted clustering algorithm, which is scalable and can handle sparse data. The paper proposes a comprehensive approach to semantic relations acquisition whereas existing studies often use one or two approaches. The domain knowledge maps produced by the system represents an added advantage over existing approaches to automatic thesaurus construction in that clusters are formed using semantic relations between domain terms. Thus while offering a meaningful synthesis of the information contained in the original corpus through clustering, the results can be used for knowledge organization tasks (thesaurus building and ontology population) The system also constitutes a platform for performing several knowledge‐oriented tasks like science and technology watch, textmining, query refinement.

Abstract

Purpose — This chapter describes how incoherent government policies implemented in the first two decades (1970–1990) following the official recognition of Information science (IS) as an academic discipline within the broader interdiscipline of Information and Communication Sciences (ICS), shaped the current landscape of IS in France. This led to a narrow conception of IS often reduced to a technical specialty solving the problem of information explosion by setting up bibliographic databases, document indexing and delivery services.

Design/methodology/approach — The approach is historical and comparative. The author relies on earlier accounts by previous French authors and performs a comparison with the situation of IS in Anglophone countries (United States mostly).

Findings — The historical narrow conception of IS is now outdated. IS neither plays the role of gatekeeper anymore to scientific and technical information nor to information access since the generalisation of Internet search engines. Its scientific community in France lacks identity and is fast dwindling. Also, its problematics are not properly identified.

Research limitations/implications — Field work involving interviews of French figures and archival research could not be carried out in the limited time and means available. This needs to be done in the future.

Practical implications — This chapter should stimulate more comparative approach on the way Library & Information Science (LIS) is structured in other countries. Although the French situation appears unique in that IS is embedded within an interdiscipline (ICS) and does not exist autonomously, other similarities could be found in other countries where IS has had a similar trajectory and lessons could be learned.

Social implications — This chapter may serve as a stepping stone for future research on the historical foundations and epistemology of IS in France and elsewhere. It should also help disseminate to the LIS community at large how the French IS landscape has been evolving, since most French scholars publish in French, language has indeed been a barrier to disseminating their research worldwide.

Originality/value — There has not been a recent and comprehensive study which has looked at the peculiarities of the French IS landscape but also at the commonalities it shares with the situation of IS in other countries with respect to how the field originated and how it has evolved.

Abstract

Library and information science (LIS) is an academic, intellectual and industrial field with a large international reach. LIS educates library and information professionals, and is an active field in research and practice with a tradition of research development, standards, networks and distribution worldwide. The field has in recent years experienced a significant growth and development in all parts of the world, however, the field's long-term future is at the same time being challenged by new technologies, education changes and the development of new industries. A refocusing from a library to an information focus is in development within the LIS field. However, the field of information is also being grasped by the technology fields on the one hand and the psychological/behavioural fields on the other. Unfortunately for the field of LIS, information is now everyone's problem and of greater interest to more scientific fields and in addition, industry and government are looking for information management solutions that require technological development based on the psychological quality research. How the LIS field survives over the next 20 years will be played out in educational and industry environments globally.

Abstract

David Ellis is Professor in the Department of Information Studies at Aberystwyth University. He was previously lecturer and senior lecturer in the Department of Information Studies, University of Sheffield. He has a PhD and an MA in Information Studies from the University of Sheffield, and a BA in Philosophy and Politics from the University of Durham. His PhD study of the information behaviour of academic social scientists represented one of the first attempts to apply a rigorous qualitative methodology to modelling the information seeking patterns of social science researchers and was subsequently extended to studies of scientists in both academic and industrial research environments. These interests were further developed in the course of the uncertainty in information seeking project carried out in collaboration with researchers at the University of Sheffield and the University of North Texas. Professor Ellis has published extensively in the information studies field, his work has been recognised as representing a distinct, substantive and methodological contribution to the fields of information behaviour and information retrieval research, and is widely cited in both. His current research interests are in the areas of information behaviour, information and knowledge management and information systems. Professor Ellis's professional activities have included service on the UK Research Assessment Exercise, Peer Review Panel for Library and Information Management, and Research Convenor of the Arts and Humanities Research Council (AHRC) Peer Review Panel for Librarianship, Information and Museum Studies. He is a member of the AHRC and the Economics and Social Sciences Research Council (ESRC) Peer Review Colleges and Research Notes Editor of the International Journal of Information Management.

Abstract

Purpose

In this article, the author discusses works from the French Documentation Movement in the 1940s and 1950s with regard to how it formulates bibliographic classification systems as documents. Significant writings by Suzanne Briet, Éric de Grolier and Robert Pagès are analyzed in the light of current document-theoretical concepts and discussions.

Design/methodology/approach

Conceptual analysis.

Findings

The French Documentation Movement provided a rich intellectual environment in the late 1940s and early 1950s, resulting in original works on documents and the ways these may be represented bibliographically. These works display a variety of approaches from object-oriented description to notational concept-synthesis, and definitions of classification systems as isomorph documents at the center of politically informed critique of modern society.

Originality/value

The article brings together historical and conceptual elements in the analysis which have not previously been combined in Library and Information Science literature. In the analysis, the article discusses significant contributions to classification and document theory that hitherto have eluded attention from the wider international Library and Information Science research community. Through this, the article contributes to the currently ongoing conceptual discussion on documents and documentality.

Abstract

Purpose

The purpose of this paper is to propose an appropriate symbolic representation, as well as its metaphorical interpretation, to illustrate the special role of information in the knowledge acquisition process.

Design/methodology/approach

Besides the literature review, this is a speculative study based on a symbolic and metaphorical point of view.

Findings

The proposed symbolic representation was derived from the conceptual designation of information “as a flow” and, accordingly, by the corresponding redrawing of the data-information-knowledge-wisdom (DIKW) pyramid. The knowledge acquisition process is symbolically represented by the growth of a “tree of knowledge” which is planted on a “data earth,” filled with “information sap” and lit by the rays of the “sun of the mind,” a new symbol of the concept of wisdom in the DIKW model. As indicated, a key concept of this metaphorical interpretation is the role of “information sap” which rises from the roots of the “tree of knowledge” to the top of the tree and it is recognized as an invisible link between “world of data” and “world of knowledge.” This concept is also proposed as a new symbolic representation of the DIKW model.

Originality/value

On the basis of specific symbolic-metaphorical representation, this paper provides a relatively new concept of information which may help bridge observed gaps in the understanding of information in various scientific fields, as well as in its understanding as an objective or subjective phenomenon.
