Answering English queries in automatically transcribed Arabic speech

There are several well-known approaches to parsing Arabic text in preparation for indexing and retrieval. Techniques such as stemming and stopping have been shown to improve search results on written newswire dispatches, but few comparisons are available on other data sources. In this paper, we apply several alternative stemming and stopping approaches to Arabic text automatically extracted from the audio soundtrack of news video footage, and compare these with approaches that rely on machine translation of the underlying text. Using the TRECVID video collection and queries, we show that normalisation, stopword- removal, and light stemming increase retrieval precision, but that heavy stemming and trigrams have a negative effect. We also show that the choice of machine translation engine plays a major role in retrieval effectiveness

an important partnership for decades

Graesch, J. P., Hensel-Börner, S., & Henseler, J. (2021). Information technology and marketing: an important partnership for decades. Industrial Management and Data Systems, 121(1), 123-157. https://doi.org/10.1108/IMDS-08-2020-0510Purpose: The enabling technologies that emerged from information technology (IT) have had a considerable influence upon the development of marketing tools, and marketing has become digitalized by adopting these technologies over time. The purpose of this paper is to demonstrate the impacts of these enabling technologies on marketing tools in the past and present and to demonstrate their potential future. Furthermore, it provides guidance about the digital transformation occurring in marketing and the need to align of marketing and IT. Design/methodology/approach: This study demonstrates the impact of enabling technologies on the subsequent marketing tools developed through a content analysis of information systems and marketing conference proceedings. It offers a fresh look at marketing's digital transformation over the last 40 years. Moreover, it initially applies the findings to a general digital transformation model from another field to verify its presence in marketing. Findings: This paper identifies four eras within the digital marketing evolution and reveals insights into a potential fifth era. This chronological structure verifies the impact of IT on marketing tools and accordingly the digital transformation within marketing. IT has made digital marketing tools possible in all four digital transformation levers: automation, customer interaction, connectivity and data. Practical implications: The sequencing of enabling technologies and subsequent marketing tools demonstrates the need to align marketing and IT to design new marketing tools that can be applied to customer interactions and be used to foster marketing control. Originality/value: This study is the first to apply the digital transformation levers, namely, automation, customer interaction, connectivity and data, to the marketing discipline and contribute new insights by demonstrating the chronological development of digital transformation in marketing.authorsversionpublishe

Business Benefits from Enterprise Systems Implementation in New Zealand

Organisations rely on their enterprise systems (ES) to integrate and optimise business processes, automate business transactions and share context-rich information to support decision making, according to the literature. But does this happen and how? This study examines key benefits that organisations generally seek from ES implementations, how ES data are transformed into knowledge, how this knowledge is utilised to achieve business benefits and the critical success factors for this process. Findings indicate that key benefits New Zealand organisations expect from ES include improve information flow, reduce out-of-inventory events and implement process efficiencies. An important finding is that New Zealand companies have only recently started tracking benefits through analytical processes to optimise and realise business value from their ES investment. Implications for practice are discussed with a focus on usability of ES and its information

The Information Systems Academic Discipline in Australia

This book represents the second phase of a multi-method, multi-study of the ‘Information Systems Academic Discipline in Australia’. Drawing on Whitley’s Theory of Scientific Change, the study analysed the degree of ‘professionalisation’ of the Information Systems Discipline, the overarching research question being ‘To what extent is Information Systems a distinct and mature discipline in Australia?’ The book chapters are structured around three main sections: a) the context of the study; b) the state case studies; and c) Australia-wide evidence and analysis. The book is crafted to be accessible to IS and non-IS types both within and outside of Australia. It represents a ‘check point’; a snapshot at a point in time. As the first in a hoped for series of such snap-shots, it includes a brief history of IS in Australia, bringing us up to the time of this report. The editorial team comprises Guy Gable, architect and leader; Bob Smyth, project manager; Shirley Gregor, sponsor, host and co-theoretician; Roger Clarke, discipline memory; and Gail Ridley, theoretician. In phase two, the editors undertook to examine each component study, with a view to arriving at an Australia-wide perspective

Institutional vs. Non-institutional use of Social Media during Emergency Response: A Case of Twitter in 2014 Australian Bush Fire

© 2017, Springer Science+Business Media, LLC. Social media plays a significant role in rapid propagation of information when disasters occur. Among the four phases of disaster management life cycle: prevention, preparedness, response, and recovery, this paper focuses on the use of social media during the response phase. It empirically examines the use of microblogging platforms by Emergency Response Organisations (EROs) during extreme natural events, and distinguishes the use of Twitter by EROs from digital volunteers during a fire hazard occurred in Australia state of Victoria in early February 2014. We analysed 7982 tweets on this event. While traditionally theories such as World System Theory and Institutional Theory focus on the role of powerful institutional information outlets, we found that platforms like Twitter challenge such notion by sharing the power between large institutional (e.g. EROs) and smaller non-institutional players (e.g. digital volunteers) in the dissemination of disaster information. Our results highlight that both large EROs and individual digital volunteers proactively used Twitter to disseminate and distribute fire related information. We also found that the contents of tweets were more informative than directive, and that while the total number of messages posted by top EROs was higher than the non-institutional ones, non-institutions presented a greater number of retweets

Towards an approach for weaving preferences into web services operation

Existing approaches on Web services privacy dominate solutions from a users’ perspective, giving little consideration to the preferences of Web service providers. The integration of service providers’ preferences into Web services’ operations is discussed in this paper. A Web service provider indicates peer Web services that it could interact with as well as the data that they could exchange with. We focus on Privacy and (trust) Partnership preferences based on which, we develop a Specification for Privacy and Partnership Preferences (S3P). This specification suggests a list of exceptional actions to deploy at run-time when these preferences are not met. An integration model of these preferences into Web services design is illustrated throughout a running scenario, and an implementation framework proves the S3P concept.Zakaria Maamar, Quan Z.

Kajian tadbir urus teknologi maklumat organisasi awam di Gorontao-Indonesia

The concept of information technology (IT) governance has become a trend in public organizations sector in most countries. However, the implementation of IT governance in Indonesia continues to face problems and challenges, including weak understanding and assessment processes activities based on IT implementation. In addition, empirical studies related to IT governance within public organizations in Indonesia are limited. The main objective of this study is to develop an IT governance model in public organizations in Gorontalo, Indonesia. This study adapted the Control Objective for Information and Related Technology (COBIT) model which conformed to the principles of management of IT resources that form the basis of IT governance in Indonesia by studying the contribution factors of implementation IT governance in public organizations. This study used quantitative and qualitative methods which involved questionnaires, interviews, observations and documents. Quantitative data was collected via questionnaires that were distributed to 367 and the return rate was 90.6 percent. This data was analyzed using Structural Equation Modeling (SEM) to validate the research model and test the proposed research hypotheses. Semi-structured interviews were used to obtain the management's views about IT governance activities and their implementation. Observations and documents analysis were used to observe how the activities and find data, information and resources for implementation of IT governance. The results show that the proposed model conforms to COBIT. The study also proves that COBIT together with the goal of and the principles of IT resource management that form the basis of IT governance in Indonesia has managed to enrich the model in describing understanding and implementation of IT governance. The results of this study contribute to knowledge to best practice of IT governance. This study can be used as a guide the best practice IT governance in Indonesia in the futur
