Geographical query formulation is one of the key difficulties for users in search engines. The purpose of this study is to improve geographical search by proposing a novel geographical query reformulation (GQR) technique using a geographical taxonomy and word senses.Design/methodology/approachThis work introduces an approach for GQR, which combines a method of query components separation that uses GeoNames, a technique for reformulating these components using WordNet and a geographic taxonomy constructed using the latent semantic analysis method.FindingsThe proposed approach was compared to two methods from the literature, using the mean average precision (MAP) and the precision at 20 documents (P@20). The experimental results show that it outperforms the other techniques by 15.73% to 31.21% in terms of P@20 and by 17.81% to 35.52% in terms of MAP.Research limitations/implicationsAccording to the experimental results, the best created taxonomy using the geographical adjacency taxonomy builder contains 7.67% of incorrect links. This paper believes that using a very big amount of data for taxonomy building can give better results. Thus, in future work, this paper intends to apply the approach in a big data context.Originality/valueDespite this, the reformulation of geographical queries using the new proposed approach considerably improves the precision of queries and retrieves relevant documents that were not retrieved using the original queries. The strengths of the technique lie in the facts of reformulating both thematic and spatial entities and replacing the spatial entity of the query with terms that explain the intent of the query more precisely using a geographical taxonomy.

Grounded in the principal-agent theory, this study aims to develop and test hypotheses too, investigate how the firm’s strategic orientations, namely, innovation, growth, differentiation and cost leadership impact the chief information officer (CIO) reporting relationship and structure.Design/methodology/approachThe study uses content analysis to analyze a data set of press releases collected from the LexisNexis Academic wire index. The press releases were issued by firms when they hired CIOs between 2003 and 2007, yielding 128 firms, which had specific information about the CIO reporting relationship and structure.FindingsThe results reveal that firms seeking an innovation, growth or differentiation strategy have their CIOs reporting to the chief executive officer.Research limitations/implicationsThe current study is motivated by the desire to replicate and extend the works of previous researchers who have assessed various CIO issues. Replication takes several forms such as the use of similar or different data sets, different research environments or reinvestigating research concepts through a different theoretical lens. This study makes use of a multi-firm data set spanning five years and the principal-agent theory as the theoretical framework to explore the CIO reporting relationship and structure. Although this study focuses on the hiring trends and the strategic orientations of the firms, future studies should explore other characteristics associated with the CIOs that might have an impact on the reporting relationship such as the years of experience, age, educational background of CIOs and information technology budgets.Practical implicationsThe existing literature has not settled the debate as to whom the CIO should be reporting to and understanding the reporting relationships is important because, in many firms, the organizational structures and the reporting relationships are indicative of the power dynamics and how the organizational resources are controlled and shared.Originality/valueReplication studies are important because they confirm, reinforce, extend and provide reliability to the paradigms and knowledge in the discipline, as well as offer reliability of the results upon which scientific progress is based.

Social networking services/systems (SNSs) have grown in popularity in the past decade. However, while some have been abandoned by their once loyal users, others have grown in popularity. Literature provides diverse and often conflicting justifications for this phenomenon. Seeking a credible explanation, this study aims to examine the roles of system-like trust and habit in SNS use continuance.Design/methodology/approachThis study conducted a comprehensive review of related literature to formulate an extended model of information technology (IT) continuance. A cross-sectional field survey was used to collect data from 401 university-student Facebook users. The research model was evaluated using structural equation modeling.FindingsThe results indicate that trust in technology and hedonic motivation are important direct influences on end-user continuance intention (CI), while habit is not. Interestingly, the most salient (indirect) predictor of CI is confirmation of (user) expectations.Practical implicationsThe study suggests a set of practical steps that managers and practitioners can undertake to support users’ decisions to continue using the systems.Originality/valueThis paper advances IT continuance research by theorizing that trust in technology along with habit and hedonic motivation positively influence CI. In addition, the study enhances the concept of perceived usefulness by modeling this unitary measure as a multidimensional construct.

This study aims to examine the impact of cultural familiarity with images on the memorability of recognition-based graphical password (RBG-P).Design/methodology/approachThe researchers used a between-group design with two groups of 50 participants from China and the Kingdom of Saudi Arabia, using a webtool and two questionnaires to test two hypotheses in a four-week long study.FindingsThe results showed that culture has significant effects on RBG-P memorability, including both recognition and recall of images. It was also found that the login success rate depreciated quickly as time progressed, which indicates the memory decay and its effects on the visual memory.Research limitations/implicationsCollectively, these results can be used to design universal RBG-Ps with maximal password deflection points. For better cross-cultural designs, designers must allow users from different cultures to personalize their image selections based on their own cultures.Practical implicationsThe RBG-P interfaces developed without consideration for users’ cultures may lead to the construction of passwords that are difficult to memorize and easy to attack. Thus, the incorporation of cultural images is indispensable for improving the authentication posture.Social implicationsThe development of RBG-P with cultural considerations will make it easy for the user population to remember the password and make it more expensive for the intruder to attack.Originality/valueThis study provides an insight for RBG-P developers to produce a graphical password platform that increases the memorability factor.

The purpose of this study is to concurrently test the effect of cognitive absorption and perceived social presence on technology acceptance model core variables, e-satisfaction and e-retention among undergraduate students of Northern Malaysian public universities.Design/methodology/approachTo empirically test the model, the authors developed quantitative research by collecting data from 730 undergraduate students of public universities in the Northern states of Malaysia. Partial least squares–structural equation modeling was used to analyze the data.FindingsThe results of the study reveal that cognitive absorption has a direct significant and positive effect on perceived usefulness and perceived ease of use of e-learning platforms and an indirect effect on e-satisfaction and e-retention. Equally, perceived social presence has a direct positive and significant effect on perceived ease of use and an indirect effect on e-satisfaction and e-retention, while e-satisfaction positively and significantly influences electronic retention. However, perceived social presence has an insignificant effect on perceived usefulness.Practical implicationsThe findings of this study provide insights to practitioners, academia and university management, policymakers, designers and marketers on how to use the selected variables to improve the e-learning systems generally, and LearningZone Moodle in particular.Originality/valueSeveral studies have been conducted in the domain of electronic learning; none of them, however, concurrently linked cognitive absorption and perceived social presence with technology acceptance model core factors to predict e-satisfaction and e-retention using LearningZone Moodle. This study helps the research community to fill this gap as the literature lacks a concerted discussion concerning these variables to significantly predict e-satisfaction and e-retention in an online learning context.
