PurposeThe purpose of this paper is to examine and verify the competitive intelligence tools Alexa and SimilarWeb, which are broadly used for website traffic data estimation. Tested tools belong to the state of the art in this area.Design/methodology/approachThe authors use quantitative approach. Research was conducted on a sample of Czech websites for which there are accurate traffic data values, against which the other data sets (less accurate) provided by Alexa and SimilarWeb will be compared.FindingsThe results show that neither tool can accurately determine the ranking of websites on the internet. However, it is possible to approximately determine the significance of a particular website. These results are useful for another research studies which use data from Alexa or SimilarWeb. Moreover, the results show that it is still not possible to accurately estimate website traffic of any website in the world.Research limitations/implicationsThe limitation of the research lies in the fact that it was conducted solely in the Czech market.Originality/valueSignificant amount of research studies use data sets provided by Alexa and SimilarWeb. However, none of these research studies focus on the quality of the website traffic data acquired by Alexa or SimilarWeb, nor do any of them refer to other studies that would deal with this issue. Furthermore, authors describe approaches to measuring website traffic and based on the analysis, the possible usability of these methods is discussed.

Detailed Interpretation

Purpose The purpose of this paper is to evaluate ontologies with respect to the linked data principles. This paper presents a concrete interpretation of the four linked data principles applied to ontologies, along with an implementation that automatically detects violations of these principles and fixes them (semi-automatically). The implementation is applied to a number of state-of-the-art ontologies. Design/methodology/approach Based on a precise and detailed interpretation of the linked data principles in the context of ontologies (to become as reusable as possible), the authors propose a set of algorithms to assess ontologies according to the four linked data principles along with means to implement them using a Java/Jena framework. All ontology elements are extracted and examined taking into account particular cases, such as blank nodes and literals. The authors also provide propositions to fix some of the detected anomalies. Findings The experimental results are consistent with the proven quality of popular ontologies of the linked data cloud because these ontologies obtained good scores from the linked data validator tool. Originality/value The proposed approach and its implementation takes into account the assessment of the four linked data principles and propose means to correct the detected anomalies in the assessed data sets, whereas most LD validator tools focus on the evaluation of principle 2 (URI dereferenceability) and principle 3 (RDF validation); additionally, they do not tackle the issue of fixing detected errors.

Purpose The aim of this paper is to present an online framework for building a domain taxonomy, called TaxoLine, from Web documents automatically. Design/methodology/approach TaxoLine proposes an innovative methodology that combines frequency and conditional mutual information to improve the quality of the domain taxonomy. The system also includes a set of mechanisms that improve the execution time needed to build the ontology. Findings The performance of the TaxoLine framework was applied to nine different financial corpora. The generated taxonomies are evaluated against a gold-standard ontology and are compared to state-of-the-art ontology learning methods. Originality/value The experimental results show that TaxoLine produces high precision and recall for both concept and relation extraction than well-known ontology learning algorithms. Furthermore, it also shows promising results in terms of execution time needed to build the domain taxonomy.

Key Issues

Purpose A large and growing number of researchers set out to cross-culturally examine empirical relationships. The purpose of this paper is to provide researchers, who are new to multicountry investigations, a discussion of the issues that one needs to address in order to be properly prepared to begin the cross-cultural analyses of relationships. Design/methodology/approach Thus, the authors consider two uniquely different but integrally connected challenges to getting ready to conduct the relevant analyses for just such multicountry studies. The first challenge is to collect the data. The second challenge is to prepare (clean) the collected data for analysis. Accordingly, the authors divide this paper into two parts to discuss the steps involved in both for multicountry studies. Findings The authors highlight the fact that in the process of collecting, there are a number of key issues that should be kept in mind including building trust with new team members, leading the team, and determining sufficient contribution of team members for authorship. Subsequently, the authors draw the reader’s attention to the equally important, but often-overlooked, data cleaning process and the steps that constitute it. This is important because failing to take serious the quality of the data can lead to violations of assumptions and mis-estimations of parameters and effects. Originality/value This paper provides a useful guide to assist researchers who are engaged in data collection and cleaning efforts with multiple country data sets. The review of the literature indicated how truly important a guideline of this nature is, given the expanding nature of cross-cultural investigations.

Purpose Simulation is a well-known technique for using computers to imitate or simulate the operations of various kinds of real-world facilities or processes. The facility or process of interest is usually called a system, and to study it scientifically, we often have to make a set of assumptions about how it works. These assumptions, which usually take the form of mathematical or logical relationships, constitute a model that is used to gain some understanding of how the corresponding system behaves, and the quality of these understandings essentially depends on the credibility of given assumptions or models, known as VV&A (verification, validation and accreditation). The main purpose of this paper is to present an in-depth theoretical review and analysis for the application of VV&A in large-scale simulations. Design/methodology/approach After summarizing the VV&A of related research studies, the standards, frameworks, techniques, methods and tools have been discussed according to the characteristics of large-scale simulations (such as crowd network simulations). Findings The contributions of this paper will be useful for both academics and practitioners for formulating VV&A in large-scale simulations (such as crowd network simulations). Originality/value This paper will help researchers to provide support of a recommendation for formulating VV&A in large-scale simulations (such as crowd network simulations).

Purpose This paper aims to consider the state of the art of the tourism sector in Portugal, identifying the main problems and some challenges and solutions for the future. Design/methodology/approach The main political decisions related to tourism were analyzed and related to the sector´s future performance. Findings Portugal has been elected the best leading destination of the world, but it is important to outline the strategies needed to retain the quality of life of Portuguese residents and to keep and improve the experience of the tourist. This could be achieved by promoting “Portugal as a whole” (“Portugal por Inteiro”), applying policies of cohesion – policies that promote the development of the entire country, from the interior to the coastline, from the north to the south and the islands. Originality/value This paper presents the perspective of the Center of Portugal Tourism Entity (Turismo Centro de Portugal) and how this tourist destination contributes to the national strategies outlined for the coming years.

Similarity Model

Purpose This paper aims to improve the recommendations performance for cold-start users and controversial items. Collaborative filtering (CF) generates recommendations on the basis of similarity between users. It uses the opinions of similar users to generate the recommendation for an active user. As a similarity model or a neighbor selection function is the key element for effectiveness of CF, many variations of CF are proposed. However, these methods are not very effective, especially for users who provide few ratings (i.e. cold-start users). Design/methodology/approach A new user similarity model is proposed that focuses on improving recommendations performance for cold-start users and controversial items. To show the validity of the authors’ similarity model, they conducted some experiments and showed the effectiveness of this model in calculating similarity values between users even when only few ratings are available. In addition, the authors applied their user similarity model to a recommender system and analyzed its results. Findings Experiments on two real-world data sets are implemented and compared with some other CF techniques. The results show that the authors’ approach outperforms previous CF techniques in coverage metric while preserves accuracy for cold-start users and controversial items. Originality/value In the proposed approach, the conditions in which CF is unable to generate accurate recommendations are addressed. These conditions affect CF performance adversely, especially in the cold-start users’ condition. The authors show that their similarity model overcomes CF weaknesses effectively and improve its performance even in the cold users’ condition.

Purpose – This paper aims at summing up the main criticisms concerning quality management (QM) in order to address them through objective arguments or extant research. Since its diffusion in the Occident in the 70s, QM gained as much approvals as criticisms. Therefore, with 40 years distance, it seems useful to sum up the main criticisms addressed to QM, to present a synthesis of the answers provided by researchers to these criticisms and to propose extant research when it appears that some criticisms have not received yet the adequate response. Design/methodology/approach – This paper is based on a literature review. Findings – This paper comes up with a list of the main criticisms addressed to QM. Then, main causes of criticisms are identified: ignorance of QM, confusion concerning QM definitions and theory and misuse of QM by senior managers. At last, QM organizational solutions are proposed which answer most expressed criticisms. Extant research tracks are considered for those relevant criticisms which have not been sufficiently addressed until now. Research limitations/implications – Further research will look into depicting a survey conducted among QM professionals concerning QM criticisms in their organization and confronting them to these academic results. Originality/value – This paper actualizes and completes Giroux and Landry’s (1998) article which dealt extensively with QM criticisms. Professionals will find in this paper answers to most criticisms against QM and a better understanding of the present limits of this discipline. Researchers will be provided with a state of the art concerning this sensitive topic, allowing them to go deeper in the fields that require special attention.

Purpose – The purpose of this paper is to identify and articulate concepts and approaches to qualitative generalisation that will offer qualitative accounting researchers avenues for enhancing and justifying the general applicability of their research findings and conclusions. Design/methodology/approach – The study and arguments draw from multidisciplinary approaches to this issue. The analysis and theorising is based on published qualitative research literatures from the fields of education, health sciences, sociology, information systems, management and marketing, as well as accounting. Findings – The paper develops two overarching generalisation concepts for application by qualitative accounting researchers. These are built upon a number of qualitative generalisation concepts that have emerged in the multidisciplinary literatures. It also articulates strategies for enhancing the generalisability of qualitative accounting research findings. Research limitations/implications – The paper provides qualitative accounting researchers with understandings, arguments and justifications for the generalisability of their research and the related potential for wider accounting and societal contributions. It also articulates the key factors that impact on the quality of research generalisation that qualitative researchers can offer. Originality/value – This paper presents the most comprehensively sourced and developed approach to the concepts, strategies and unique deliverables of qualitative generalising hitherto available in the accounting research literature.

Quality Register

Purpose After the “quantity era,” today higher education has entered into the “quality era” and as “the gate keepers of quality,” quality assurance agencies (QAAs) are playing more and more irreplaceable important roles and their social status are becoming more and more prominent. However, how to guarantee the quality of the QAAs? Who can review the QAAs? The purpose of this paper is based exploration of these questions. Design/methodology/approach Following the founding of the European Quality Assurance Register (EQAR) for Higher Education, the Asia Pacific Quality Register (APQR) became the second in the international quality assurance (QA) networks to implement QA register, in 2015 with initiative of Asia-Pacific Quality Network. Findings This paper first retrospects the history and process of APQR, and subsequently the implementation of APQR is described in detail from the two aspects of the criteria and the procedure, and at the end, the paper concludes with a summary of the three characteristics of this first formal implement of APQR: APQR is an international register open to all the QAAs; APQR emphasizes characteristics evaluation of diversity; and APQR highlights the combination of quantitative assessment and qualitative assessment. Originality/value Today on the international stage of QA, APQR has emerged as “the watchman of quality” in the Asia-Pacific region as counterpart of EQAR in Europe. How far away does such newly emerging form of guaranteeing the QAAs’ quality go forward, what is its future prospects and other concerning issues, are some of the question that need enthusiastic attention and contribution.
