Query Model

Purpose When accessing structured contents in XML form, information requests are formulated in the form of special query languages such as NEXI, Xquery, etc. However, it is not easy for end users to compose such information requests using these special queries because of their complexities. Hence, the purpose of this paper is to automate the construction of such queries from common query like keywords or form-based queries. Design/methodology/approach In this paper, the authors address the problem of constructing queries for XML retrieval by proposing a semantic-syntax query model that can be used to construct different types of structured queries. First, a generic query structure known as semantic query structure is designed to store query contents given by user. Then, generation of a target language is carried out by mapping the contents in semantic query structure to query syntax templates stored in knowledge base. Findings Evaluations were carried out based on how well information needs are captured and transformed into a target query language. In summary, the proposed model is able to express information needs specified using query like NEXI. Xquery records a lower percentage because of its language complexity. The authors also achieve satisfactory query construction rate with an example-based method, i.e. 86 per cent (for NEXI IMDB topics) and 87 per cent (NEXI Wiki topics), respectively, compare to benchmark of 78 per cent by Sumita and Iida in language translation. Originality/value The proposed semantic-syntax query model allows flexibility of accommodating new query language by separating the semantic of query from its syntax.

Problems associated with the improve ment of information retrieval for open environment are considered and the need for it’s semantization is grounded. Thecurrent state and prospects of development of semantic search engines that are focused on the Web information resources processing are analysed, the criteria for the classification of such systems are reviewed. In this analysis the significant attention is paid to the semantic search use of ontologies that contain knowledge about the subject area and the search users. The sources of ontological knowledge and methods of their processing for the improvement of the search procedures are considered. Examples of semantic search systems that use structured query languages (eg, SPARQL), lists of keywords and queries in natural language are proposed. Such criteria for the classification of semantic search engines like architecture, coupling, transparency, user context, modification requests, ontology structure, etc. are considered. Different ways of support of semantic and otology based modification of user queries that improve the completeness and accuracy of the search are analyzed. On base of analysis of the properties of existing semantic search engines in terms of these criteria, the areas for further improvement of these systems are selected: the development of metasearch systems, semantic modification of user requests, the determination of an user-acceptable transparency level of the search procedures, flexibility of domain knowledge management tools, increasing productivity and scalability. In addition, the development of means of semantic Web search needs in use of some external knowledge base which contains knowledge about the domain of user information needs, and in providing the users with the ability to independent selection of knowledge that is used in the search process. There is necessary to take into account the history of user interaction with the retrieval system and the search context for personalization of the query results and their ordering in accordance with the user information needs. All these aspects were taken into account in the design and implementation of semantic search engine "MAIPS" that is based on an ontological model of users and resources cooperation into the Web.

Purpose This paper presents the results of a qualitative study that involved students of an interdisciplinary PhD program. The study objective was to gather requirements to create a knowledge graph information system. The purpose of this study was to determine information-seeking practices and information needs of this community, to inform the functionalities of a proposed system, intended to help students with relevant resource discovery and decision-making. Design/methodology/approach The study design included semi-structured interviews with eight members of the community, followed by a website usability study with the same student participants. Findings Two main information-seeking styles are recognized and reported through user personas of international and domestic (USA) students. The findings show that the useful information resides within the community and not so much on the program website. Students rely on peer communication, although they report lack of opportunities to connect. Students’ information needs and information seeking are dependent on their progress through the program, as well as their motivation and the projected timeline. Practical implications Considering the current information needs and practices, a knowledge graph hosting both information on social networks and the knowledge produced by the activities of the community members would be useful. By recording data on their activities (for example, collaboration with professors and coursework), students would reveal further useful system functionalities and facilitate transfer of tacit knowledge. Originality/value Aside from the practical value of this research that is directly influencing the design of a system, it contributes to the body of knowledge on interdisciplinary PhD programs.

Purpose Materiality as an emerging trend aims to make sustainability reports (SR) more relevant for stakeholders. This paper aims to investigate whether the reporting practice of electric utility companies (EUC) is in compliance with the materiality principle of the Global Reporting Initiative (GRI) when disclosing SR. Design/methodology/approach A twofold content analysis focusing on material aspects (MAs) is conducted, followed by correlation analysis. Logic and conversation theory (LCT) serves to evaluate the communication quality of documented materiality in SR by EUC. Findings The coverage and quality of documented MAs in SR by EUC do not meet the requirements for relevant and transparent communication. Materiality does not guide the reporting practice and is not taken seriously. Research limitations/implications Mediocre quality of coverage and communication in SR shows that stakeholders’ information needs are not considered adequately. The content analysis is limited in focusing on merely documented aspects rather than on actual performance. Originality/value This study considers the quality of communication of documented materiality through the lens of LCT. It contributes to the academic debate by introducing LCT as a viable theoretical perspective for analyzing SR. The paper evaluates GRI-G4 reporting practices in the electricity sector, which, while under-researched is crucial for sustainability. It also contributes to the emerging body of empirical research on the relevance of materiality as a guiding principle for sustainability reporting.

PurposeAs academic social Q&A networking websites become more popular, scholars are increasingly using them to meet their information needs by asking academic questions. However, compared with other types of social media, scholars are less active on these sites, resulting in a lower response quantity for some questions. This paper explores the factors that help explain how to ask questions that generate more responses and examines the impact of different disciplines on response quantity.Design/methodology/approachThe study examines 1,968 questions in five disciplines on the academic social Q&A platform ResearchGate Q&A and explores how the linguistic characteristics of these questions affect the number of responses. It uses a range of methods to statistically analyze the relationship between these linguistic characteristics and the number of responses, and conducts comparisons between disciplines.FindingsThe findings indicate that some linguistic characteristics, such as sadness, positive emotion and second-person pronouns, have a positive effect on response quantity; conversely, a high level of function words and first-person pronouns has a negative effect. However, the impacts of these linguistic characteristics vary across disciplines.Originality/valueThis study provides support for academic social Q&A platforms to assist scholars in asking richer questions that are likely to generate more answers across disciplines, thereby promoting improved academic communication among scholars.

Clear Idea

Purpose Query-based summarization approaches might not be able to provide summaries compatible with the user’s information need, as they mostly rely on a limited source of information, usually represented as a single query by the user. This issue becomes even more challenging when dealing with scientific documents, as they contain more specific subject-related terms, while the user may not be able to express his/her specific information need in a query with limited terms. This study aims to propose an interactive multi-document text summarization approach that generates an eligible summary that is more compatible with the user’s information need. This approach allows the user to interactively specify the composition of a multi-document summary. Design/methodology/approach This approach exploits the user’s opinion in two stages. The initial query is refined by user-selected keywords/keyphrases and complete sentences extracted from the set of retrieved documents. It is followed by a novel method for sentence expansion using the genetic algorithm, and ranking the final set of sentences using the maximal marginal relevance method. Basically, for implementation, the Web of Science data set in the artificial intelligence (AI) category is considered. Findings The proposed approach receives feedback from the user in terms of favorable keywords and sentences. The feedback eventually improves the summary as the end. To assess the performance of the proposed system, this paper has asked 45 users who were graduate students in the field of AI to fill out a questionnaire. The quality of the final summary has been also evaluated from the user’s perspective and information redundancy. It has been investigated that the proposed approach leads to higher degrees of user satisfaction compared to the ones with no or only one step of the interaction. Originality/value The interactive summarization approach goes beyond the initial user’s query, while it includes the user’s preferred keywords/keyphrases and sentences through a systematic interaction. With respect to these interactions, the system gives the user a more clear idea of the information he/she is looking for and consequently adjusting the final result to the ultimate information need. Such interaction allows the summarization system to achieve a comprehensive understanding of the user’s information needs while expanding context-based knowledge and guiding the user toward his/her information journey.

Purpose The purpose of this paper is to challenge librarians to reconceptualize their professional self-image and practice so that it more closely aligns with the information science discipline that is part of the Masters of Library and Information Science degree. Design/methodology/approach This column is primarily theoretical and philosophical but also draws on the author’s observations of trends and patterns in both librarianship and changes in information needs in recent years. Findings Urgent, high-cost information needs created by COVID-19 and climate change coexist in a reality where technological change has made traditional librarian roles and functions less critical. By developing their information science skills and strengthening their professional identity as information scientists, librarians have the opportunity to address the urgent information needs of the day while remaining highly relevant professionals. Practical implications Librarians will need to strengthen their science-related skills and knowledge and begin to promote themselves as information scientists. Social implications Librarians are in a position to make a meaningful contribution to two of the most pressing challenges of the day, climate change and dealing with the COVID-19 pandemic. Originality/value This paper is relevant to all librarians at any stage of their career. It will help them to reflect on both their skillset and career path and to make any needed adjustments so that they can remain relevant in a volatile and demanding information environment.

Purpose This study aims to investigate the characteristics, as well as the purpose and posts of the COVID-19 Facebook groups. Design/methodology/approach A systematic search for COVID-19 Facebook groups was conducted on June 1, 2020. Characteristics of the groups were examined using descriptive statistics. Mann-Whitney test was used to study the differences between groups. The study of the most popular groups’ posts was also carried out using the content analysis method. Findings The groups had a combined membership of 2,729,061 users. A total of 147,885 posts were received. There were about approximately 60% public groups. A high percentage of the groups (86.5%) had descriptions. The results showed a significant relationship between the groups’ description status and the number of members (p-value = 0.016). The majority of COVID-19 Facebook groups (56%) were created to meet their members’ information needs. The highest number of studied posts were related to vaccination (35.2%), followed by curfew rules (19.6%) and symptoms (10.6%). Originality/value Translating these insights into policies and practices will put policymakers and health-care providers in a stronger position to make better use of Facebook groups to support and enhance public knowledge about COVID-19.

Purpose The purpose of this paper is to verify if the gender effects described in the wine consumer behaviour literature, namely, concerning information search and the motivations to buy, may be explained by the mediating effect of subjective knowledge, taking into consideration that the importance of knowledge in the decision process is gender specific. Design/methodology/approach A path analysis was modelled with an exogenous variable (gender), a mediating variable (subjective knowledge) and four dependent variables (need for information and three motivational dimensions). The model was assessed with empirical data obtained from a sample of 523 shoppers in large supermarkets in the areas of Lisbon and Oporto, Portugal. Structured interviews were conducted at checkout, collecting information on the relevant variables. Scales measuring the latent variables (knowledge, information and motivation) were previously validated through confirmatory factor analysis in a sample of 217 wine consumers. Findings Subjective knowledge fully mediates the effects of gender on motivation and information needs. Men think of themselves as more knowledgeable in wines and the mediation effect explains why, compared to women, they use less personal information sources and are more motivated to purchase wine. Practical implications The authors suggest promotion programmes in large supermarkets focussing on opportunities for wine knowledge development. Originality/value The study contributes to the literature by introducing and validating an alternative formulation of gender effects on wine shopping, emphasising the role of the purchaser’s perceived or subjective knowledge.

Asymmetric Cost Behavior

Purpose The purpose of this paper is to provide further empirical evidence on the asymmetric cost behavior, cost stickiness, in an emerging country, Egypt, which lacks academic research on this subject. Design/methodology/approach This study uses multiple regression analysis to analyze the behavior of selling, general, and administrative costs (SG&A) and cost of goods sold (CGS) individually and jointly using total costs (TC) for the period 2004-2011 for Egyptian-listed firms. In addition, the study compares the cost behavior three years prior to and after the application of the corporate governance code in Egypt in 2007. Findings The results indicate that asymmetric cost behavior is common among Egyptian-listed firms as their SG&A, CGS, and TC were found to be sticky during the study period. The application of the corporate governance code in Egypt was found to affect the nature of SG&A – the behavior of these costs changed from sticky before the code to anti-sticky after the application of the code. Moreover, the code was found to affect the magnitude of stickiness of both CGS and TC. Originality/value Greater awareness about cost behavior is important for emerging markets such as Egypt in order to protect investors’ interests and satisfy their information needs. To the best of our knowledge, this study is the first to provide evidence on cost stickiness in Egypt. Moreover, this study provides further evidence on the correlation between corporate governance and asymmetric cost behavior.

Purpose – The purpose of this paper is to provide an overview of higher education students’ experiences in using smartphones for learning purposes, and their perceptions of the suitability of smartphones for learning. Design/methodology/approach – A qualitative research method is applied to data collection and analysis by following the grounded theory approach. Data were gathered by an online focus group involving Library and Information Science (LIS) students from University of Hong Kong and University of Tsukuba (Japan). Findings – LIS students at both universities regularly use smartphones for communication, socializing, entertainment and other daily information needs. The findings show that LIS students commonly use smartphones for learning and consider smartphones to be very useful for their academic work. They use smartphones to access course materials, search library catalog, discuss course assignments with peers, take notes, etc. Although both academic libraries involved offer a variety of services for mobile devices, these services are still not used frequently. A major barrier to using smartphone for academic learning is the smartphone’s small screen. Research limitations/implications – The study relies on a convenience sample, restricted to students from two universities, one from Hong Kong and the other from Japan. Further research on a larger sample is recommended. Originality/value – The study adds to the knowledge of smartphone actual use for learning purposes and provides study participants’ insights on the usefulness of smartphones for learning.
