Abstract

Purpose

The immense quantity of available unstructured text documents serve as one of the largest source of information. Text classification can be an essential task for many purposes in information retrieval, such as document organization, text filtering and sentiment analysis. Ensemble learning has been extensively studied to construct efficient text classification schemes with higher predictive performance and generalization ability. The purpose of this paper is to provide diversity among the classification algorithms of ensemble, which is a key issue in the ensemble design.

Design/methodology/approach

An ensemble scheme based on hybrid supervised clustering is presented for text classification. In the presented scheme, supervised hybrid clustering, which is based on cuckoo search algorithm and k-means, is introduced to partition the data samples of each class into clusters so that training subsets with higher diversities can be provided. Each classifier is trained on the diversified training subsets and the predictions of individual classifiers are combined by the majority voting rule. The predictive performance of the proposed classifier ensemble is compared to conventional classification algorithms (such as Naïve Bayes, logistic regression, support vector machines and C4.5 algorithm) and ensemble learning methods (such as AdaBoost, bagging and random subspace) using 11 text benchmarks.

Findings

The experimental results indicate that the presented classifier ensemble outperforms the conventional classification algorithms and ensemble learning methods for text classification.

Originality/value

The presented ensemble scheme is the first to use supervised clustering to obtain diverse ensemble for text classification

Abstract

Purpose

This paper aims to review the literature on stakeholder identification and classification related to sustainability marketing from 1998 to 2012 and provides a generalized approach to stakeholder identification and classification in the field of sustainability marketing.

Design/methodology/approach

Beginning with brief introductions of the key concepts, the research discusses landmark studies on the subject in detail. The review process then begins by identifying and selecting relevant research papers from various online databases. Finally, 60 research papers are found suitable for the review and are examined to theoretically analyze the stakeholder identification and classification schemes used in sustainability marketing literature.

Findings

This study identifies trends of growth in stakeholder identification and classification literature. In addition, there are two major findings. First, stakeholder identification can be done with the help of previous studies, with support from managers or via a combination of both. Second, future research can adopt generic stakeholder classification schemes or relative classification schemes based on dimensions of sustainability to classify stakeholders in relation to sustainability marketing. In relative stakeholder classification, regulatory stakeholders may be considered separately.

Research limitations/implications

While the literature review may be incomplete, as it uses only a title-based advanced search, researchers and practitioners can still benefit from this simplified approach to manage stakeholders.

Originality/value

The study introduces a generalized approach to stakeholder identification and classification related to sustainability marketing and provides a bibliography from 1998 to 2012 that can be used by academics and managers.

The study aims to explore the classification of electronic games in Dewey decimal classification (DDC) and The Library of Congress classification (LCC) schemes.

Abstract

Purpose

The study aims to explore the classification of electronic games in Dewey decimal classification (DDC) and The Library of Congress classification (LCC) schemes.

Design/methodology/approach

The study adopted a comparative analytical method to explore the topic in both the DDC and the LCC schemes by comparing its processing method in both schemes. The study measures the extent to which both schemes succeed in allocating notations covering the topic’s literature.

Findings

The study reached several results, the most important of which are: the difference between the two main cognitive sections, to which they belong to the topic, namely, arts and recreation (700) in the DDC scheme and the geography section (G) in the LCC scheme, while they were found to share the same sub-section scheme. The two schemes do not allocate notations to address the subject of electronic games as literature and other notations that have not been embodied for electronic games themselves or in the form of a compact disc or other media.

Originality/value

As far as we know, this is the first paper that compares the treatment of video games in DDC and Library of Congress classification schemes. The study allows for understanding the difference in the treatment of topics in both schemes, which would help in the decision of the adoption of a particular classification scheme.

Abstract

Purpose

The growing number of publications on knowledge management (KM) has addressed heterogeneous topics that lack integration and classification. This article closes the classification gap by presenting a classification scheme, providing an integrated overview of KM publications.

Design/methodology/approach

The development of the classification scheme follows a multistep approach. By applying a taxonomy development method, the results of a previous content analysis of 4,290 publications were processed to integrate 3,780 keywords into a classification scheme.

Findings

The classification scheme consists of 13 main categories and subcategories with six levels of detail. The scheme covers not only KM-specific keywords but also keywords from related disciplines, indicating a strong interdependence with related research domains.

Research limitations/implications

The scheme provides a starting point for ongoing collaboration within the KM community with the aim of improving the classification results and refining the scheme to manifest the core identity.

Practical implications

The scheme is helpful in understanding whether KM implementation activities in organisations are aligned with overall research activities and topics covered by publications.

Originality/value

Developing a scheme based on a prior content analysis turns out to be a unique and innovative approach that has never before been done in the KM domain.

Abstract

Purpose

The purpose of this paper is to draw an exact and accurate picture of classification problems being faced by libraries having a reasonable amount of collections on Islam. Different classification systems have been developed during the last two centuries to organize library materials. Where these systems provided libraries with better solution for organization of materials, the systems have also some limitations. Religious materials are one of the areas where these systems could not satisfy a reasonable number of libraries. The libraries that have rich collections on Islam are also facing such problems. This study has been conducted with the aim of addressing this problem.

Design/methodology/approach

The study comprises a precise review of literature relevant to this problem, along with the collection and analysis of data from such libraries from all the main cities of Pakistan. The data have been collected using the interview technique.

Findings

The review of literature and empirical data collected for this study show that the libraries are facing problems regarding the classification of materials where there are rich collections on Islam. The standard classification systems have not provided proper place and enumeration to Islamic topics in their schemes. There is no standard or uniform practice among the libraries to classify materials on Islam. Different libraries are using different systems, which has resulted placement of same materials at different locations. There is no coordination among libraries having rich collections on Islam for some common plan of action to resolve the problem in hand. No work on automated classification has been done in Pakistan so far and this is the area that needs working on in the future.

Research limitations/implications

The paper focusses on materials in libraries in one country only, however highlights issues relevant to other Islamic countries in organizing such materials.

Originality/value

The paper discusses an area of professional concern that has been discussed widely in Islamic countries, but only in a limited fashion outside of Islamic countries. Thus the paper should be of interest to researchers and practioners interested in cataloging theory.

Abstract

Purpose

Projects have high stakes in how they are categorized. The final place of a project within a classification scheme depends on the inclusion or exclusion of certain classification criteria. So far, many researchers and organizations have used a variety classification criteria to construct different project classification schemes. However, most of these classification criteria have been taken for granted and the process of selecting them to categorize projects still remains a black box. The purpose of this paper is to open the black box of classification process and explain how it is reflected in picking the classification criteria.

Design/methodology/approach

Drawing on insights from cognitive psychology’s literature, the authors examine the main views of classification process to provide insight into the unknown or implicit reasons that one might have to pick particular attributes as project classification criteria.

Findings

The authors argue that classification occurs in the eye of the beholder; it is not only the project’s features per se but also the classifier’s “goals, ideal and preference” or “knowledge of causal relations” that are reflected in the classification criteria.

Research limitations/implications

By elaborating the classification process, the authors brought the project context into the big picture of classification and provide a more rational, and coherent picture of how project classification works. This contributes to a theoretical blind spot, raised by prior researchers, related to the selection of project classification criteria.

Practical implications

Understanding classification processes will reduce the ambiguities, inconsistencies and multiple interpretations of project categories and help practitioners increase their projects’ visibility and legitimacy within an already established classification scheme. These implications help organizations in addressing some of the main obstacles to using categorization in project management practice.

Originality/value

The review of prior work in the category research literature and the insights from this paper will provide project management scholars with a useful toolbox for future research on project classification, which has long been understudied.

Abstract

Purpose

Classification schemes make things happen. The Australian Disability Discrimination Act (DDA), which derives its classification system from the World Health Organization's International Classification of Functioning, Disability and Health (ICF), legislates for adjustments to support the inclusion of people with disability. This study explores how students with disability enrolled in a university experience the systems intended to facilitate their studying “on the same basis” as students without disability.

Design/methodology/approach

Through an online questionnaire and interviews comprising open and closed questions made available to students registered with the disability services unit of a university and follow-up interviews with a small number of students, students’ views of their own disability and effects on their participation in learning were gathered, alongside reports of their experiences of seeking support in their learning. Interview data and responses to open-ended questions were analysed using a priori and emergent coding.

Findings

The findings demonstrate that students are aware of the workings of the classification scheme and that most accept them. However, some students put themselves outside of the scheme, often as a way to exercise autonomy or to assert their “ability”, while others are excluded from it by the decisions of academic staff. Thus, the principles of fairness and equity enshrined in legislation and policy are weakened.

Originality/value

Through the voices of students with disability, it is apparent that, even though a student's classification according to the DDA and associated university policy remains constant, the outcomes of the workings of the scheme may reveal inconsistencies, emerging from the complexity of bureaucracy, processes and the exercises of power.

Abstract

Purpose

The purpose of this paper is to identify, review and evaluate international marketing (IM) studies in the domain of cultural country classification (1985‐2006).

Design/methodology/approach

First, articles in which an “original” classification is developed are identified. Then, the paper characteristics are summarized using Ronen and Shenkar's characteristics. Eventually, Hunt's evaluation criteria are used to evaluate these classifications.

Findings

Summarizing and evaluating the selected papers reveals that the authors of the selected papers do not always seem to explicitly consider Ronen and Shenkar's useful recommendations concerning questionnaire and sample characteristics. Moreover, evaluation seems to indicate that Hunt's evaluation criteria are not always met.

Research limitations/implications

It is recommended that future cultural country classification researchers consider Ronen and Shenkar's recommendations. Moreover, researchers might explicitly specify the concept of culture and/or incorporating other influencing factors. It is also recommended that researchers develop their own classification scheme to check whether the scheme meets Hunt's evaluation criteria. Other researchers might try to contribute to a convergence of the cultural country classification domain by empirically testing newly developed typologies; refining studies; assigning other countries; and testing comparatively existing classifications.

Practical implications

Practitioners might think of grouping countries culturally for fine‐tuning marketing strategy. When seeking for co‐ordination and synergy, multinationals can use country cluster offices as a step‐stone or alternative to more centralized, global headquarters.

Originality/value

Besides, Ronen and Shenkar's paper in 1985 – another evaluation paper in the domain of cultural country classification and IM was not discovered. The paper tries to offer some useful recommendations to both scientific researchers and practitioners.

Abstract

Probably no aspect of librarianship presents such variations of practice in individual libraries as does the provision of subject catalogues. The author catalogue, which tells the user whether a given work of which he knows the author and title is in the library, must necessarily take a similar form everywhere, and such variations as do exist in the treatment of certain types of heading—that of academies is a case in point—are quickly assimilated by the reader as he moves from library to library. The same cannot be said of the catalogue which tells the user what works are to be found in the library on a given topic. In the Anglo‐Saxon countries subject catalogues may be arranged, if indeed they exist at all, according to a variety of systems, and even where one of the accepted classification schemes or lists of subject headings is used the local modifications are often legion. Many university and research libraries find that no existing scheme offers an arrangement of the whole field of knowledge which reflects the approach to which their readers are accustomed; and certainly no ready‐made scheme is entirely suitable for a university library in the United Kingdom, although many libraries do attempt to provide a useful arrangement both of the books on the shelves and of the entries in the subject catalogue by adapting Dewey, the Brussels decimal classification, or the Library of Congress classification. Bliss, when his full scheme has been published, will probably be found to provide the arrangement most suitable for use in academic libraries, but even his admirable classification fails to provide a scheme which can be identified at all points with the approach which is required in a library which serves first and foremost the teaching of a university.

Abstract

As a discipline, the history of science is comparatively young. Although Baden‐Powell's Historical view of the progress of the physical and mathematical sciences from the earliest ages to the present time and Whewell's History of the inductive sciences from the earliest to the present times, both pioneer works in the field, were published in 1834 and 1837 respectively, the history of science as a subject in its own right may be said to have only come into existence in this century. Interest in the history of individual sciences, particularly mathematics and medicine, began much earlier and quite a few periodicals devoted to them were inaugurated during the last century. On the other hand, most of the periodicals dealing with the history of science as a whole were begun during the last two decades and only a few go back to the beginning of this century. The first volume of Mitteilungen zur Geschichte der Medizin und der Naturwissenschaften was published in Leipzig in 1902; Archiv für die Geschichte der Naturwissenschaften und der Technik followed in 1909, and Rivista di Storia (critica) delle Scienze mediche e naturali in 1910. Isis, originally subtitled Revue consacrée à l'histoire de la science (now An international review devoted to the history of science and its cultural influences), was founded in 1912 by George Sarton, the first number appearing in March 1913. It began its life in Belgium, but after the invasion of that country moved with its first editor to the United States. Volume 2, begun in June 1914, was completed in September 1919. From the beginning an international review, it changed its ‘editorial language’, as it were, from French to English in 1920, but it continued to publish articles and papers in the main European languages. From the first issue, one of its principal features was a bibliography of the literature of the history of science.
