The main goal of this study is to employ unsupervised (lexicon-based) learning approaches to identify readers' emotional dimensions and thumbs-up empathy reactions to reviews of online travel agency apps based on appraisal and stimulus–organism–response (SOR) theories.

Using the Google Play Scraper, we gathered a total of 402,431 reviews from the Google Play Store for two travel agency apps, Tripadvisor and Booking.com. Following the filtering and cleaning of user reviews, we used lexicon-based unsupervised machine learning algorithms to investigate the associations between various emotional dimensions of reviews and review readers' thumbs-up reactions.

The study's findings reveal that the sentiment of different sorts of reviews has a substantial influence on review readers' emotional experiences, causing them to give the app a thumbs up review. Furthermore, readers' thumbs-up responses to the text reviews differed depending on the eight emotional aspects of the reviews.

The results of this research can be applied in the development of online travel agency apps. The findings suggest that app developers can enhance users' emotional experiences by considering the sentiment and emotional aspects of reviews in their design and implementation. Additionally, the results can be used by travel agencies to improve their online reputation and attract more customers by providing a positive user experience.

The findings of this research have the potential to have a significant impact on society by providing insights into the emotional experiences of users when they engage with online travel agency apps. The study highlights the importance of considering the emotional aspect of user reviews, which can help app developers to create more user-friendly and empathetic products.

The current study is the first to evaluate the impact of users' thumbs-up empathetic reactions on user evaluations of online travel agency applications using unsupervised (lexicon-based) learning methodologies.

The purpose of this paper is to explore practical ways in which librarians may better assist, understand and manage a library user's experience.

This paper is based on earlier work by Mills where 34 academics were interviewed on their information seeking behaviour. The concepts of affect and emotional intelligence have been introduced so information professionals can obtain a more clear understanding of the information environment.

In order to connect more closely with their user populations' information professionals could consider the following: embrace the key tenets of emotional intelligence as useful assistance strategies in user‐librarian interaction; understand that personal interaction is important for many users; understand that such interaction can offer valuable insights into user understandings of the role of the library; understand that there is more to a library than resource access; understand that not all users share the same perceptions as librarians of the information values of such tools as catalogues and databases; appreciate that users see many roles for a library and these are individually constructed based upon past experience and current needs; extending the physical boundaries of the library into user communities is important for role development and accept that the key marketing strategy of commercial retailers to get customers to “buy” and return to buy, is relevant in environments such as libraries.

The paper builds upon research on the information seeking behaviour of academics and explores the idea that users select information sources for more than cognitive reasons, i.e. just to find out. The importance of the emotional aspect of user interaction with sources, including information professionals, in their search for information has been neglected. It is necessary to re‐examine why and for what reasons users discriminate in their choice of information sources.

The aim of this paper is to develop a comprehensive model that combines brand awareness, brand image, brand emotional attachment, brand evaluation and also shows how these constructs affect e-loyalty through the use of travel-related online social network (OSN) websites.

Based on an in-depth literature review, a conceptual e-loyalty model was developed. Empirical data were collected through a web-based questionnaire from 236 respondents. A structural equation modeling was utilized to test the e-loyalty model.

Results indicate that brand awareness positively affects brand image. Brand awareness directly and indirectly influences brand emotional attachment and brand evaluations. The total effects of brand awareness and brand image suggest that higher awareness level and positive image encourage OSN users to be more loyal. In return, this increases the probability that OSN members will repurchase through the OSN websites that they are emotionally connected with. Study results further suggest that there is no difference between the conceptualization of loyalty and the medium used when brands attempt to create consumer loyalty either in the traditional offline medium or the online medium.

Study results suggest that travel-related brands should consider brand emotional attachment and brand evaluation as the most important antecedents to e-loyalty, while e-loyalty results in the increased transaction intentions of online users.

Very few studies have so far looked at the cause-and-effect relationship between brand emotional attachment and brand evaluation, and e-loyalty through the use of travel-related OSN websites. Study results confirm that the conceptualization of loyalty is similar to the conceptualization of e-loyalty.

This paper aims to present a detailed description of Tukuchiy, a framework to dynamically generate adapted user interfaces. Tukuchiy is based on Runa-Kamachiy, a conceptual integration model that combines human–computer interaction (HCI) standards to create user interfaces with user-centered concepts usually addressed by adaptation.

The first step was the definition of three profiles: user, context and interface. These profiles contain information, such as user disabilities, location characteristics (e.g. illumination) and preferences (e.g. interface color or type of system help). The next step is to define the rules that ensure usability for different users. All of this information is used to create the Tukuchiy framework, which generates dynamic user interfaces, based on the specified rules. The last step is the validation through a prototype called Idukay. This prototype uses Tukuchiy to provide e-learning services. The functionality and usability of the system was evaluated by five experts.

To validate the approach, a prototype of Tukuchiy, called Idukay, was created. Idukay was evaluated by experts in education, computing and HCI, who based their evaluation in the system usability scale (SUS), a standard usability test. According to them, the prototype complies with the usability criteria addressed by Tukuchiy.

This work was tested in an academic environment and was validated by different experts. Further tests in a production environment are required to fully validate the approach.

Tukuchiy generates adapted user interfaces based on user and context profiles. Tukuchiy uses HCI standards to ensure usability of interfaces that dynamically change during execution time. The interfaces generated by Tukuchiy adapt to context, functionality, disabilities (e.g. color blindness) and preferences (usage and presentation) of the user. Tukuchiy enforces specific HCI standards for color utilization, button size and grouping, etc., during execution.

The purpose of this paper is to present an integrative framework for handling the security and usability conflicts during the system development lifecycle. The framework has been formulated while considering key concerns raised after conducting a series of interviews with practitioners from the industry. The framework is aimed at assisting system designers and developers in making reasonably accurate choices when it comes to the trade-offs between security and usability. The outcomes of using the framework are documented as design patterns, which are disseminated among the community of system designers and developers for use in other but similar contexts.

A design science research approach was used to develop the integrative framework for usable security. Interviews were conducted for identification of the key concerns; however, the framework was validated during a workshop. Moreover, to validate the patterns’ template and the usable security pattern identified after instantiating the framework, a survey instrument was used.

It is important to consider the usability aspect in the development of security systems; otherwise, the systems, despite being secure against attacks, would be susceptible to user mistakes leading to compromises. It is worthwhile to handle usable security concerns right from the start of system development life cycle. Design patterns can help the developers in assessing the usability of their security options.

The framework would assist the designers and developers in handling the security and usability conflicts right from the start of the system development life cycle. The patterns documented after using the framework would help not only the designers and developers working in the industry but also freelancers.

The authors present a novel framework to handle the security and usability conflicts during the system development life cycle. The development process of the framework was driven by the concerns raised after a series of interviews with the practitioners from industry. The framework presented in this paper was validated during a workshop in which it was exposed for review and comments by the participants from the industry. To demonstrate the use of patterns in general and the framework in particular, a case study featuring smart grids from the domain of cyber-physical systems is presented, which (to the best of the authors’ knowledge) features the first work relevant to usable security in the domain of cyber-physical systems.

The blockchain technology is based on distributed ledger. Many stakeholders, such as developers, entrepreneurs and technology lovers, consider the blockchain as an economic and business re-creation that is faced with numerous challenges in its application. Blockchain technology is the backbone of many digital currencies, i.e. Bitcoin and Ethereum. Although presently digital currencies are recognized as payment and exchange instruments in many countries, the economic sanctions imposed on some countries have restricted the possibility of the trading. So, this study seeks to evaluate the adoption of blockchain for digital currency use in Iran in the shadow of economic sanctions.

The developed value-based technology adoption model and smart PLS software have been used in this research. The statistical population of the study was people active in the Iranian stock market; the purpose for this selection was their familiarity with financial and digital currency issues.

The results show that the terms of sanctions, usage and facilitating conditions are directly related to users' perceived value of digital currency and its use; As a result, in a sanctioned country like Iran, the use of digital currencies is being accepted as a way of rolling out economic sanctions and thus making commercial payments.

As well as the fact that evaluating the adoption of the blockchain technology in a sanctioned country like Iran is considered as the originality aspect of the research, applying an extended model in the technology adoption is also the research innovation.

The purpose of this paper seeks to develop a motivation-based complementary framework for temporally dynamic user preferences to facilitate optimal timing in web personalisation. It also aims to highlight the benefits of considering user motivation when addressing issues in temporal dynamics.

Through theory, a complementary framework and propositions for motivation-based temporal dynamics for further testing are created. The framework is validated by feeding back findings, whereas some of the propositions are validated through an experiment.

The suggested framework distinguishes two ways (identifying/learning and shifting) of using a motive-based approach to temporal dynamics in web personalisation. The suggested outcomes include enhanced timing in matching current preferences and improved conversion. Validation measures predominantly support both the framework and the tested propositions. The theoretical basis for the approach paves a path towards refined psychological user models; however, currently on a complementary level.

While the framework is validated through feeding back findings, and some of the propositions are validated through basic experimentation, further empirical testing is required.

A generalised approach for complementing personalisation procedures with motivation-based temporal dynamics is offered, with implications for both user modelling and preference matching.

This paper offers novel insights to web personalisation by considering the in-depth effects of user motivation.

The purpose of this paper is to identify the role of emotional aspects in information retrieval of PhD students from the web.

From the methodological perspective, the present study is experimental and the type of study is practical. The study population is PhD students of various fields of science. The study sample consists of 50 students as selected by the stratified purposive sampling method. The information aggregation is performed by observing the records of user’s facial expressions, log file by Morae software, as well as pre-search and post-search questionnaire. The data analysis is performed by canonical correlation analysis.

The findings showed that there was a significant relationship between emotional expressions and searchers’ individual characteristics. Searchers satisfaction of results, frequency internet search, experience of search, interest in the search task and familiarity with similar searches were correlated with the increased happy emotion. The examination of user’s emotions during searching performance showed that users with happiness emotion dedicated much time in searching and viewing of search solutions. More internet addresses with more queries were used by happy participants; on the other hand, users with anger and disgust emotions had the lowest attempt in search performance to complete search process.

The results imply that the information retrieval systems in the web should identify emotional expressions in a set of perceiving signs in human interaction with computer, similarity, face emotional states, searching and information retrieval from the web.

The results explicit in the automatic identification of users’ emotional expressions can enter new dimensions into their moderator and information retrieval systems on the web and can pave the way of design of emotional information retrieval systems for the successful retrieval of users of the network.

This study investigates the determinants of effective human and artificial intelligence (AI) relationship-building strategies for brands. It explores the antecedents and consequences of consumers' interactant satisfaction with communication and identifies ways to enhance consumer purchase intention via AI chatbot promotion.

Microsoft Xiaoice served as the focal AI chatbot, and 331 valid samples were obtained. A two-stage structural equation modeling-artificial neural network approach was adopted to verify the proposed theoretical model.

Regarding the IQ (intelligence quotient) and EQ (emotional quotient) of AI chatbots, the multi-dimensional social support model helps explain consumers' interactant satisfaction with communication, which facilitates affective attachment and purchase intention. The results also show that chatbots should emphasize emotional and esteem social support more than informational support.

Brands should focus more on AI chatbots' emotional and empathetic responses than functional aspects when designing dialogue content for human–AI interactions. Well-designed AI chatbots can help marketers develop effective brand promotion strategies.

This research enriches the human–AI interaction literature by adopting a multi-dimensional social support theoretical lens that can enhance the interactant satisfaction with communication, affective attachment and purchase intention of AI chatbot users.

Inspired by the dynamic changes in our daily lives enabled via quantified-self technologies and the urgent need for more studies on the human-computer interaction design mechanisms adopted by these applications, this study explores the value of user affective experience mirroring and examines the empowerment effect of meaningful gamification in a psychological self-help system (PSS) that aids people in work stress relief.

Based on an analysis of the existing systems and theories in relevant fields, we conducted mixed-method research, involving semi-structured interviews, experience sampling experiments and user bio data triangulations, to identify the benefits of user affective experience mirroring and examine the impact of visual impact metaphor–based (VIM) meaningful gamification on PSS users.

For a gamified PSS, users generally perceive VIM as arousing more feelings of enjoyment, empathy, trust and usefulness, empowering them to gain more mastery and control over their emotional well-beings, especially with relieving their occupational stress and upbringing their level of perceived happiness. Overtime, VIM-based meaningful gamification further boosts such value of a PSS.

Weaving together meaningful gamification and psychological empowerment theories, the results emphasized that successful empowerment of user through gamification in PSSs relies heavily on whether a deeper and meaningful affective connection can be established with the users, in short, “meaningful gamification for psychological empowerment”. Such an understanding, as demonstrated in our research framework, also sheds light on the design theories for persuasive technology and human influence tactics during human computer interactions.

The results of the study demonstrate to practitioners how to make the best use of gamification strategies to deeply relate to and resonate with users. Even without complicated game-play design, meaningful gamification mechanisms, such as VIM facilitate the empowerment of users while gaining their appreciation, establishing a deeper connection with them and eventually generating persuasive effects on intended future behavioural outcomes.

The effective management of work-related stress with handy tools such as a VIM-based PSS can be beneficial for many organizations and, to a large extent, the society.

This study proposed and empirically demonstrated the empowerment effect of meaningful gamification for PSS users. In this cross-disciplinary study, theories from different research domains were synthesized to develop a more thorough and multi-faceted understanding of the optimal design strategies for emerging information systems like this VIM-based PSS.
