Abstract

Purpose

The paper aims to present an approach for services in the domain of tourism based on a software application in the area of ontology engineering, showing a methodology for intelligent knowledge‐based P2P networks creation, in the tourism knowledge domain, given that, potential tourists share and organize their experiences, interests and knowledge. Using the proposed software application, they automatically exchange their knowledge, with an intelligent and transparent way, with other users that have the same or similar interests and make use of it.

Design/methodology/approach

The approach followed was categorizing tourism‐related interests and services into ontologies (system and user), then comparing them, using intelligent algorithms, suggesting new, unknown to the user, interests. The data were evaluated by experts in order to provide a guide for correct (according to the expert) interestingness of profile concepts.

Findings

The paper presents the outcomes of the software used, running on mobile devices, showing the connection for them, among user knowledge profiles and tourism services. It has been found that the return results (concepts) are of high interestingness to the user.

Research limitations/implications

Experiments have been performed with one central ontology, used as reference and two user ontologies at the same time. The authors would suggest more experimentation, with more users connected concurrently.

Practical implications

Of high practical importance is the creation of intelligent social networking processes and user communities based on interests for further e‐commerce activities, based on a semantic framework.

Originality/value

The paper fulfils the need for intelligent interaction and distribution of knowledge and content to users in an autonomous way, anywhere.

Abstract

Purpose

The goals of this study are: to evaluate the merits of a newly developed health information retrieval system; to investigate users' search strategies when using the new search system; and to study the relationships between users' search strategies and their prior topic knowledge.

Design/methodology/approach

The paper developed a new health information retrieval system called MeshMed. A term browser and a tree browser are included in the new system in addition to the traditional search box. The term browser allows a user to search Medical Subject Heading (MeSH) terms using natural language. The tree browser presents a hierarchical tree structure of related MeSH terms. A user study with 30 participants was conducted to evaluate the benefits of MeshMed.

Findings

The paper found that MeshMed provides a user with more choices to select an appropriate searching component and form more effective search strategies. Based on the time a participant spent using different MeshMed components, the paper identified three different search styles: the traditional style, the novel style, and the balanced style, which falls in between. MeshMed was particularly helpful for users with low topic knowledge.

Originality/value

A new health information retrieval system (MeshMed) was designed and developed (and is currently available at http://129.89.43.129/meshmed). This is the first study to explore users' search strategies on such a system. The study results can inform the design of future clinical‐oriented health information retrieval systems.

Abstract

Purpose

The purpose of this paper is to examine the role of task and user’s topic familiarity in the evaluation of information patch (websites).

Design/methodology/approach

An experimental study was conducted in a computer laboratory to examine users’ information seeking and foraging behaviour. In total, 160 university students participated in the research. Two types of task instructions, specifically defined and non-specifically defined (general) task types were administered. Mixed methods approach involving both quantitative and qualitative thematic coding were adopted, from the data of the questionnaire surveys and post-experiment interviews.

Findings

In the context of task attributes, users who conducted information seeking task with specifically defined instructions, as compared to the non-specifically defined instructions, demonstrated stricter credibility evaluations. Evidence demonstrated the link between topical knowledge and credibility perception. Users with topical knowledge applied critical credibility assessments than users without topical knowledge. Furthermore, the evidential results supported that the level of difficulty and knowledge of the topic or subject matter associated with users’ credibility evaluations. Users who have lesser or no subject knowledge and who experienced difficulty in the information search tended to be less diagnostic in their appraisal of the information patch (website or webpages). Users equipped with topical knowledge and who encountered less difficulty in the search, exhibited higher expectation and evaluative criteria of the information patch.

Research limitations/implications

The constraints of time in the lab experiment, carried out in the presence of and under the observation of the researcher, may affect users’ information seeking behaviour. It would be beneficial to consider users’ information search gratifications and motivations in studying information evaluations and foraging patterns. There is scope to investigate users’ proficiency such as expert or novice, and individual learning styles in assessing information credibility.

Practical implications

Past studies on information evaluation, specifically credibility is often associated with users’ characteristics, source, or contents. This study sheds light on the context of task type, task difficulty and topical knowledge in affecting users’ information judgement.

Originality/value

One of the scarce studies in relating task orientation, task difficulty and topical knowledge to information evaluations.

Abstract

Purpose

The purpose of this paper is to draw on the social cognitive theory to identify the determinants of online knowledge community user continuance, which reflects a user’s continued use.

Design/methodology/approach

Based on the 271 valid responses collected from a survey, structural equation modelling was employed to examine the research model.

Findings

The results indicated that the cognitive factors of outcome expectation and the environmental factors of system quality and knowledge quality significantly affect a user’s continuance intention, which, in turn, affects continuance usage.

Research limitations/implications

The results imply that service providers need to enhance community platforms and improve knowledge quality in order to retain users and facilitate their continuance.

Originality/value

Although previous research has examined online knowledge community user behaviour from multiple perspectives such as the social exchange theory and the motivational theory, it has seldom explored the relative effects of personal cognitions and environmental factors on user behaviour. This research fills the gap.

Abstract

Examines the who, what and why of the knowledge mapping process used in the visual display of information in contemporary organizations. Knowledge mapping serves as the continuously evolving organizational memory, capturing and integrating strategic explicit knowledge within an organization and between an organization and its external environment. Knowledge map making is treated as a medium of communication over what is important and actionable information (knowledge) in organizational contexts. Effective knowledge maps take into account the who, what and why of the knowledge mapping process. Effective knowledge maps help identify intellectual capital, socialize new members, enhance organizational learning and help anticipate impending threats and/or opportunities.

Abstract

Purpose

The purpose of this paper is to answer the question: why Google Answers and Yahoo! Kimo Knowledge+, both virtual communities built on users asking and answering questions with different rewarding mechanisms, have different outcomes.

Design/methodology/approach

Based on the theory of reasoned action (TRA), the authors developed the constructs, including self‐efficacy, altruism, reward, and the sense of virtual community, that influence the intention of sharing knowledge in terms of answering questions on Knowledge+.

Findings

The results show that users showing higher levels of contribution tended to be motivated by virtual rewards, such as advanced ranks, and the need for self‐fulfillment. Additionally, for these knowledge providers, altruism is also an important factor. Therefore, these users share not because of a reward but because of altruism and fulfillment. The findings can answer why Google Answers failed with its monetary rewards but Knowledge+ remains with its virtual rewarding mechanism.

Research limitations/implications

This study extends the literature on understanding the antecedents of sharing knowledge in terms of answering others’ questions in virtual communities. Especially, it identifies different factors affecting the intention of users in different levels of engagement with the community to share knowledge.

Practical implications

The various effective factors influencing usersknowledge sharing behavior identified in this study can guide the incentive mechanism design for virtual communities.

Originality/value

Besides proposing research models to identify the constructs affecting the users’ intention to answer questions in a virtual community, such as Knowledge+, this study compares the models explaining the intention to share knowledge in different user groups with different levels of knowledge contribution. This research design is unique from the prior literatures; Moreover, the results shed light on designing incentive mechanisms for knowledge sharing in virtual communities.

Abstract

Purpose

Continuous knowledge sharing by active users, who are highly active in answering questions, is crucial to the sustenance of social question-and-answer (Q&A) sites. The purpose of this paper is to examine such knowledge sharing considering reason-based elaborate decision and habit-based automated cognitive processes.

Design/methodology/approach

To verify the research hypotheses, survey data on subjective intentions and web-crawled data on objective behavior are utilized. The sample size is 337 with the response rate of 27.2 percent. Negative binomial and hierarchical linear regressions are used given the skewed distribution of the dependent variable (i.e. the number of answers).

Findings

Both elaborate decision (linking satisfaction, intentions and continuance behavior) and automated cognitive processes (linking past and continuance behavior) are significant and substitutable.

Research limitations/implications

By measuring both subjective intentions and objective behavior, it verifies a detailed mechanism linking continuance intentions, past behavior and continuous knowledge sharing. The significant influence of automated cognitive processes implies that online knowledge sharing is habitual for active users.

Practical implications

Understanding that online knowledge sharing is habitual is imperative to maintaining continuous knowledge sharing by active users. Knowledge sharing trends should be monitored to check if the frequency of sharing decreases. Social Q&A sites should intervene to restore knowledge sharing behavior through personalized incentives.

Originality/value

This is the first study utilizing both subjective intentions and objective behavior data in the context of online knowledge sharing. It also introduces habit-based automated cognitive processes to this context. This approach extends the current understanding of continuous online knowledge sharing behavior.

Abstract

Purpose

The purpose of this paper is to examine some drivers of users’ participation in online social question-and-answer (Q&A) communities based on social cognitive theory and then identify the underlying mechanism of this process.

Design/methodology/approach

This study developed a research model to test the proposed hypotheses, and an online survey was employed to collected data. Totally, 313 valid responses were collected, and partial least squares structural equation modeling was adopted to analyze these data.

Findings

This study empirically finds that the outcome expectations (personal outcome expectations and knowledge self-management outcome expectations) are positively related to participation in online social Q&A communities. At the same time, users’ self-efficacy positively influences their participation behaviors. It can not only directly motivate users’ participation, but also indirectly promote participation behaviors through the two dimensions of outcome expectations. Besides, perceived expertise and perceived similarity are two positive and significant environmental elements affecting users’ participation.

Originality/value

This study extends the understanding about how participation behaviors will be motivated in the context of online social Q&A communities. Drawing on the social cognitive theory, constructs were established based on the features of these communities. Meanwhile, some mediating effects in the motivating process were also discussed.
