    Bibliometric Mapping of the Computational Intelligence Field

    Get PDF
    In this paper, a bibliometric study of the computational intelligence field is presented. Bibliometric maps showing the associations between the main concepts in the field are provided for the periods 1996ñ€“2000 and 2001ñ€“2005. Both the current structure of the field and the evolution of the field over the last decade are analyzed. In addition, a number of emerging areas in the field are identified. It turns out that computational intelligence can best be seen as a field that is structured around four important types of problems, namely control problems, classification problems, regression problems, and optimization problems. Within the computational intelligence field, the neural networks and fuzzy systems subfields are fairly intertwined, whereas the evolutionary computation subfield has a relatively independent position.neural networks;bibliometric mapping;fuzzy systems;bibliometrics;computational intelligence;evolutionary computation

    Some Comments on the Question Whether Co-Occurrence Data Should Be Normalized

    Get PDF
    In a recent article in JASIST, L. Leydesdorff and L. Vaughan (2006) asserted that raw cocitation data should be analyzed directly, without first applying a normalization such as the Pearson correlation. In this communication, it is argued that there is nothing wrong with the widely adopted practice of normalizing cocitation data. One of the arguments put forward by Leydesdorff and Vaughan turns out to depend crucially on incorrect multidimensional scaling maps that are due to an error in the PROXSCAL program in SPSS.multidimensional scaling;PROXSCAL;Pearson correlation;author cocitation analysis;co-occurrence data;normalization

    Discovering the dynamics of smart business networks

    Get PDF
    Earlier research discussed the necessary evolution from smart business networks, as based on process need satisfaction and governance, into business genetics [1] based on strategic bonds or decay and opportunistic complementarities. This paper will describe an approach and diffusion algorithms whereby to discover the dynamics of emergent smart business network structures and their performance in view of collaboration patterns over time. Some real life early analyses of dynamics are discussed based on cases and date from the high tech sector. Lessons learnt from such cases are also given on overall smart network dynamics with respect to local interaction strategies, as modelled like in business genetics by individual partner profiles, goals and constraints. It shows the weakness of static “business operating systems”, as well as the possibly destabilizing clustering effects amongst nodes linked to filtering, evaluation and own preferences.smart business networks; business genetics; network performance; SBN; dynamics

    How Will Online Affiliate Marketing Networks Impact Search Engine Rankings?

    Get PDF
    In online affiliate marketing networks advertising web sites offer their affiliates revenues based on provided web site traffic and associated leads and sales. Advertising web sites can have a network of thousands of affiliates providing them with web site traffic through hyperlinks on their web sites. Search engines such as Google, MSN, and Yahoo, consider hyperlinks as a proof of quality and/or reliability of the linked web sites, and therefore use them to determine the relevance of web sites with regard to search queries. In this research we investigate the potential impact of online affiliate marketing networks on the ranking of advertisersñ€ℱ web sites in search results. This article empirically explores how seven different affiliate marketing networks affect the rankings of the advertising web sites within web search engines. The field study followed intensively seven online affiliate marketing networks for twelve weeks after their launch. The results indicate that newly started affiliate networks effectively improve the rankings of advertising web sites in search engine results. Also, it was found that the effects of affiliate marketing networks on search engine rankings were smaller for advertising web sites operating in highly competitive markets. Another finding was that a growth in visitors coming from search engines was present as a result of the improvement of search engine rankings. Finally, the results indicate that cost-benefit metrics associated with affiliate marketing programs, such as the average marketing cost will decrease when the positive effects of affiliate marketing on search engine rankings are taken into account.Advertising;Hyperlinks;Online Affiliate Marketing Networks;Search Engine Rankings

    Appropriate Similarity Measures for Author Cocitation Analysis

    Get PDF
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authorsñ€ℱ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Mobile Service Affordability for the Needy, Addiction, and ICT Policy Implications

    Get PDF
    This paper links communications and media usage to social and household economics boundaries. It highlights that in present day society, communications and media are a necessity, but not always affordable, and that they furthermore open up for addictive behaviours which raise additional financial and social risks. A simple and efficient methodology compatible with state-of-the-art social and communications business statistics is developed, which produces the residual communications and media affordability budget and ultimately the value-at-risk in terms of usage and tariffs. Sensitivity analysis provides precious information on communications and media adoption on the basis of affordability. Case data are surveyed from various countries. ICT policy recommendations are made to support widespread and responsible communications access.addiction;ICT policy;communications affordability;mobile service

    Individual Tariffs for Mobile Services: Analysis of Operator Business and Risk Consequences

    Get PDF
    A design approach is offered for individual tariffs for mass customized mobile service products, whereby operators can determine their contract acceptance rules to guarantee with a set probability their minimum profit and risk levels. It uses realistic improvements to earlier reported negotiation algorithms [1], and a full operator operational model including infrastructure and content acquisition. Value at risk and profit are analyzed when a random user has consistent characteristics to a survey group, so that risk and profits are pooled. This analysis is necessary to give the supplier business guarantees to enter individual tariff agreements. A full numerical case is given for a class of mobile service.risks;mobile communication services;Individual tariffs

    From Closed-Loop to Sustainable Supply Chains: The WEEE case

    Get PDF
    The primary objective of closed-loop supply chains (CLSC) is to reap the maximum economic benefit from end-of-use products. Nevertheless, literature within this stream of research advocates that closing the loop helps to mitigate the undesirable footprint of supply chains. In this paper we assess the magnitude of such environmental gains for Electric and Electronic Equipments (EEE), based on a single environmental metric of Cumulative Energy Demand. We detail our analysis for the different phases of the CLSC, i.e. manufacturing, usage, transportation and end-of-life activities. According to our literature review, within the same group of EEE, results greatly vary. Furthermore, based on the environmental hot-spots, we propose extensions of the existing CLSC models to incorporate the CED.Closed-loop supply chains (CLSC);Cumulative energy demand;Electric and electronic equipments (EEE)
