Purpose Digital libraries and academic search engines have developed as two important online scholarly information sources with different features. The purpose of this study is to compare digital libraries and academic search engines from the perspective of the dual-route model. Design/methodology/approach Research hypotheses were developed. Potential participants were recruited to answer an online survey distributing at Chinese social media out of which 251 responses were deemed to be valid and used for data analysis. The paired samples t-test was used to compare the means. Findings Both information quality (central route) and source credibility (peripheral route) of digital libraries are significantly higher than those of academic search engines, while there is no significant difference between digital libraries and academic search engines in terms of affinity (peripheral route). Practical implications In the digital information society, the important status of digital libraries as conventional information sources should be spread by necessary measures. Academic search engines can act as complementary online information sources for seeking academic information rather than the substitute for digital libraries. Practitioners of digital libraries should value the complementary role of academic search engines and encourage users to use academic search engines while emphasizing the importance of digital libraries as conventional information sources. Originality/value According to the dual-route model, this study compares digital libraries and academic search engines in terms of information quality, source credibility and affinity, which the authors believe presents a new lens for digital libraries research and practice alike.

Dual Route Model

Purpose Digital libraries and social media have emerged as two prominent online information sources with different characteristics. The purpose of this paper is to compare digital libraries and social media from the perspective of the dual route model which outlined a general framework of central and peripheral route-induced attitude change. Design/methodology/approach Research hypotheses were developed and data collected from users of digital libraries and social media were used for data analysis. The paired samples t-test was employed to compare the means. Findings Both central route (information quality) and peripheral route (source credibility and reputation) of digital libraries are higher than those of social media. Practical implications The important status of digital libraries as conventional information sources should be propagated by various “marketing” ways. Managers of digital libraries should encourage their users to use both digital libraries and social media so that some unique advantage of social media could usefully complement digital libraries. They should also recognize the challenge brought by social media and try various ways to enhance reputation. Originality/value Building on the dual route model, this study compares digital libraries and social media in terms of the central route and peripheral route, which the authors believe presents a new lens for digital library research and practice alike.

Purpose – The elaboration likelihood model (ELM) provides a general framework for understanding the basic processes underlying the effectiveness of persuasion. The purpose of this paper is to utilize the ELM to understand the basic processes underlying the effectiveness of persuasion to use digital libraries for getting information. Design/methodology/approach – The survey data collection was conducted in one comprehensive university. The partial least squares structured equation modelling was employed to verify the research model. Findings – Source credibility and reputation have positive effects on information usefulness which further significantly impacts digital library usage for getting information. The effect of information quality on information usefulness is overpowered by reputation. Information need positively moderates the effect of information quality on information usefulness and negatively moderates the effect of reputation on information usefulness. Practical implications – Digital libraries enormously influence the way how individuals gather information over the world. However, the important status of digital libraries as conventional information sources in practice invites appreciation by more and more people. The authors believe the findings of this study provide useful insights for facilitating digital libraries to be fully accessed and utilized. Originality/value – This study explores the effects of the central route (information quality) and the peripheral route (source credibility and reputation) on digital library usage for getting information by extending the ELM with information need as a motivation variable, presenting a new lens for digital library research and practice alike.

Shared Content

Purpose This paper aims to first examine tourists’ perceptions of the source credibility and information quality of social media content to see whether they would have an impact on their perceptions of the importance of shared content on social media. The moderating role of gender in this relationship was then examined. Design/methodology/approach The research sample was composed of domestic and foreign tourists in Alanya, an important tourist destination in Turkey. The data in the current study were collected by the questionnaire method. The structural relationships in the research were examined using the partial least squares structural equation modeling, and the moderating effect of gender was examined via the partial least squares multiple group analysis. Findings According to the research findings, tourists’ perceptions of source credibility regarding social media content had a positive impact on the importance attached to non-participant shared content, whereas their perceptions of information quality had a positive impact on the importance attached to participant shared content. Furthermore, it was also observed that gender had a moderating effect on the relationship between information quality and source credibility perceptions and the importance of shared content on social media. Originality/value Two important predictive variables have been examined in the current research in term of customer-generated contents. It has been demonstrated that the effects of these predictive variables on different customer-generated types could be different. Furthermore, it has been determined that the effects of these influences differ according to the gender of the individuals following the content. Thus, the current study provides significant findings to understand the impacts of these variables on the basis of gender.

Purpose – In this study, the authors use the term “e-quality” to refer to information quality, system quality and service quality. This study aims to focus on e-quality, exploring and comparing users' perceptions of digital libraries and virtual communities in the hope that the results of this study can help lead to better understanding of the exact nature of e-quality as perceived by users. Design/methodology/approach – A large-scale survey was conducted for data collection. Data collected from 334 users of digital libraries and virtual communities were used for data analysis. Findings – The study finds that users are likely to perceive a higher level of information quality, system quality and service quality of digital libraries than of virtual communities. Practical implications – The authors suggest that librarians do not need to have concerns over the challenge brought by virtual communities, which indeed have an increasing impact on the way a lot of people seek and gather information. Instead, they should encourage their users to use both digital libraries and virtual communities. The authors believe that the usage of these two types of information sources by users can efficiently inform each other, thus facilitating the e-quality of both digital libraries and virtual communities to reach excellence. Originality/value – Building on the information systems (IS) success model, this study explores and compares users' perceptions of digital libraries and virtual communities in terms of e-quality, which the authors think presents a new view for digital library research and practice alike.

Purpose The purpose of this paper is to investigate why users are willing to diffuse healthcare knowledge in social media by drawing on the communicative ecology theory (CET) and prior research on interpersonal communication. Design/methodology/approach This paper conducts a large-scale scenario-based online survey in WeChat (the most popular social media platform in China) to test the proposed research model and hypotheses. The final data set consists of 1,039 useful responses from WeChat users. Findings The results indicate that interestingness, emotionality and institution-based trust are the strongest antecedents in predicting healthcare knowledge-diffusing likelihood, followed by usefulness, source credibility and positivity. Further, the relationship between institution-based trust and healthcare knowledge-diffusing likelihood is partially mediated by source credibility. Practical implications Healthcare practitioners who seek to motivate individuals to disseminate healthcare knowledge need to phrase or frame healthcare knowledge in a way that draws greater interest, evokes stronger emotion, increases perceived usefulness or reflects positively on themselves. Healthcare organizations should also pay attention to strengthening users’ trust in the platform and source-related information that can indicate source authority. Originality/value This study is one of the first to investigate the dissemination of healthcare knowledge in the context of social media (WeChat in particular). Compared with other types of information, healthcare knowledge is more scientific and professional to the extent that most laypersons do not have relevant expertise to directly evaluate whether the content is credible and of high quality. Rather, their sharing likelihood is dependent more on other factors than perceived information quality and credibility; those factors include platform-related factors that may play an important role but has been overlooked in prior literature on interpersonal communication. By combining CET with interpersonal communication-related research and including institution-based trust as an important determinant of healthcare knowledge dissemination, this study provides a comprehensive analysis of healthcare knowledge diffusion process.

Purpose This paper aims to focus on understanding how restaurant review sites generate trust among travellers and the effect of trust on the intention to visit and recommend restaurants while travelling. Design/methodology/approach The research model was assessed with data from a sample of 439 Spanish tourists using partial least squares structural equation modelling (PLS-SEM). Findings Information quality and source credibility are key for generating website trust. Website quality does not influence trust. Website trust is a key variable for explaining both intention to visit and recommend a restaurant, offline and online. Age is a significant moderator. Research limitations/implications This study expands the literature by assessing the antecedents and consequences of travellers’ trust in restaurant review sites during their trips. Practical implications Strategies are suggested for review sites, restaurants and destination managers. Originality/value This research enhances the knowledge of how consumers perceive restaurant review sites, and their behavioural intention while travelling.

Practical Implications

Purpose – The purpose of the paper is to understand the values perceived and the priorities attributed by the managers to four dimensions of information quality associated with meta-information commonly used in the initial selection (scanning) of content by managers: source credibility, comprehensiveness, timeliness, and confidentiality. Design/methodology/approach – The study involved conducting simulations of information selection for decision making with 124 professionals from 11 different companies. The results were analysed with content analysis techniques, nonparametric statistics, and cluster analysis. Findings – Three levels of priority were found in the managers’ information selection process: the credibility and timeliness dimensions were the most highly prioritised, the comprehensiveness dimension was the least prioritised, and the confidentiality dimension occupied an intermediate position. The preferences of the managers are for current information and a well-known source with respect to the timeliness and source credibility dimensions, respectively. Regarding the confidentiality dimension, the preference is for restricted information, valued for the desire to know. For the comprehensiveness dimension, there was no well-defined preference for managers with respect to the quantity of text in a managerial report. Practical implications – The knowledge of priorities and values attributed to the dimensions of information quality is critical for the definition of characteristics to be incorporated into information projects. Originality/value – This study's contribution is related to the process of information selection in a dynamic situation in which little time is available to information analysis.

The Impact

Purpose Many search engines in digital libraries are restricted to the terms presented in users’ queries. When users cannot represent their information needs in terms of keywords in a query, the search engine fails to provide appropriate results. In addition, most search engines do not have the ability to visualize search results for users to help them in their information journey. The purpose of this paper is to develop a new approach for search result visualization in digital libraries. The visualization approach enables subject-based visualization of search results and search queries. Design/methodology/approach To enable subject-based visualization of search results in digital libraries, new subject-based document retrieval is proposed in which each document is represented as a vector of subjects as well. Then, using a vector space model for information retrieval, along with the subject-based vector, related documents to the user’s query are retrieved, whilst each document is visualized through a ring chart, showing the inherent subjects within each document and the query. Findings The proposed subject-based retrieval and visualization approach is evaluated from various perspectives to amplify the impact of the visualization approach from users’ opinions. Users have evaluated the performance of the proposed subject-based retrieval and search result visualization, whilst 67% of users prefer subject-based document retrieval and 80% of them believe that the proposed visualization approach is practical. Research limitations/implications This research has provided a subject-based representation scheme for search result visualization in a digital library. The implication of this research can be viewed from two perspectives. First, the subject-based retrieval approach provides an opportunity for the users to understand their information needs, beyond the explicit terms in the query, leading to results, which are semantically relevant to the query. Second, the simple subject-based visualization scheme, helps users to explore the results easily, whilst allowing them to build their knowledge experience. Originality/value A new vectorized subject-based representation of documents and queries is proposed. This representation determines the semantic and subject-based relationship between a given query and documents within a digital scientific library. In addition, it also provides a subject-based representation of the retrieved documents through which users can track the semantic relationship between the query and retrieve documents, visually.

PurposeThe purpose was to evaluate the effectiveness of Google (as an international search engine) as well as of Parsijoo, Rismoon, and Yooz (as Persian search engines).Design/methodology/approachIn this research, Google search engine as an international search engine, and three local ones, Parsijoo, Rismoon, and Yooz, were selected for evaluation. Likewise, 32 subject headings were selected from the Persian Subject Headings List, and then simulated work tasks were assigned based on them. A total of 192 students from Ferdowsi University of Mashhad were asked to search for the information needed for simulated work tasks in the selected search engines, and then to copy the relevant website URLs in the search form.FindingsThe findings indicated that Google, Parsijoo, Rismoon, and Yooz had a significant difference in the precision, recall, and normalized discounted cumulative gain. There was also a significant difference in the effectiveness (average of precision, recall, and NDCG) of these four search engines in the retrieval of the Persian resources.Practical implicationsUsers using an efficient search engine will attain more relevant documents, and Google search engine was more efficient in retrieving the Persian resources. It is recommended to use Google as it has a more efficient search.Originality/valueIn this research, for the first time, Google has been compared with local Persian search engines considering the new approach (simulated work tasks).
