    An Empirical Model for Information Retrieval System Evaluation: The User's perspective
    (Computer Engineering and Intelligent Systems, 2011-01) Akhigbe, Bernard Ijesunor; Afolabi, Babajide; Adagunodo, Emmanuel Rotimi
    The aspect of time has become an issue since computers were introduced into management studies and thus highlights the need for efficient paradigm that will enable easy access to information, with much ease. But this is not the case yet, since finding the desired search engine and learning how to use them for this purpose is still time consuming. The continued dominance of measures for use in the system-centered aspect of IR evaluation, which is weak for use in user-centered IR system evaluation process, remains a challenge. Therefore the purpose of this study is to present usable measures through using an empirical from user’s perspective for use in the evaluation of IR system. The survey method, a robust multivariate mathematical model and the factor analytic method were experimented upon. Results showed that the model presented is promising concerning the challenges highlighted. Therefore user’s own knowledge, experience and searching abilities could be harnessed and implicated in IR design and evaluation. This study therefore serves as a test bed and guide to studies in this area, which results could contribute immensely to the overall improvement of the system. However, more data and a larger sample size are required to verify the proposed model in future, with other extraction techniques.

    Theory, Practice and Policy: An Inquiry into the Uptake of HCI Practices in the Software Industry of a Developing Country
    (INTERNATIONAL JOURNAL OF HUMAN–COMPUTER INTERACTION, 2016-05) Loizides, Fernando; Da Rosa, Isaias Barreto; Ogunyemi, Abiodun Afolayan; David Lamas; Adagunodo, Emmanuel Rotimi
    Withalmostfour decadesofexistenceasa community, human–computerinteraction(HCI) practice has yet to diffuseinto a large rangeof softwareindustries globally.A reviewof existing literaturesuggeststhatthe diffusion of HCI practices in software organizations lacks theoretical guidance. Although many studies have tried to facilitate HCI uptake by the software industry, there are scarce studies that consider HCI practices as innovations that software organizations could or should adopt. Furthermore, there appears to be a lack of structure in the facilitation of HCI methodological development within the specialized emerging regions field such as Sub-Saharan Africa. In order to address this gap, an exploratory investigation regarding the state of uptake of HCI practices in Nigeria is conducted. The aim of this article is to improve our understanding regarding the state of HCI uptake in developing countries and the challenges prevailing. The findings show that HCI practice still remains within its infancy stage in most software companies. Universities are also lacking the required knowledge transfer of HCI to the students, and in effect themselves contributing to the lack of HCI skills in industry. Furthermore, government policies are in need of refinement and end-users’ involvement in software development is not prioritized
