The common understanding of generalization/specialization relations assumes the relation to be equally strong between a classifier and any of its related classifiers and also at every level of the hierarchy. Assigning a grade of relative distance to represent the level of similarity between the related pairs of classifiers could correct this situation, which has been considered as an oversimplification of the psychological account of the real-world relations. The paper aims to discuss these issues.

The evaluation followed an end-user perspective. In order to obtain a consistent data set of specialization distances, a group of 21 persons was asked to assign values to a set of relations from a selection of terms from the AGROVOC thesaurus. Then two sets of representations of the relations between the terms were built, one according to the calculated concept of specialization weights and the other one following the original order of the thesaurus. In total, 40 persons were asked to choose between the two sets following an A/B test-like experiment. Finally, short interviews were carried out after the test to inquiry about their decisions.

The results show that the use of this information could be a valuable tool for search and information retrieval purposes and for the visual representation of knowledge organization systems (KOS). Furthermore, the methodology followed in the study turned out to be useful for detecting inconsistencies in the thesaurus and could thus be used for quality control and optimization of the hierarchical relations.

The use of this relative distance information, namely, “concept specialization distance,” has been proposed mainly at a theoretical level. In the current experiment, the authors evaluate the potential use of this information from an end-user perspective, not only for text-based interfaces but also its application for the visual representation of KOS. Finally, the methodology followed for the elaboration of the concept specialization distance data set showed potential for detecting possible inconsistencies in KOS.

This study aims to center on understanding how stakeholder engagement processes improve online child protection in telecom companies. The literature review and findings shed light on the management of networks to identify, prevent and mitigate the adverse impacts of information and communication technologies (ICTs)[1] and to find opportunities in terms of new policies and services development.

Three multinational telecom companies were analyzed with a qualitative focus combining three research tools: the analysis of 81 corporate reports, self-administered questionnaires and semi-structured interviews.

Firms establish a collaborative network with a large number of stakeholders such as public authorities, non-governmental organizations, educational institutions, representatives of families and expert researchers. The outcomes of these networks range from the development of new products and services (filters, child safety software and protection apps) to the co-creation of new corporate policies with a high social impact (self-regulation, sectorial codes, awareness initiatives and reporting).

This study outlines guidelines for the industry in identifying, engaging and making decisions in a collaborative way when managers have to engage with multiple stakeholders regarding child protection. The academic debate and the empirical findings have many practical implications for ICT companies whose users are children and teenagers.

Despite its significance, stakeholder management is underexplored in the literature of protection for young people. The academic field and the professional arena appear to have little to say regarding how executives manage engagement processes.

The purpose of this paper was to create a generic and flexible framework for the exploration, evaluation and side-by-side comparison of novel propulsion architectures. The intent for these evaluations was to account for varying operation strategies and to support architectural design space decisions, at the conceptual design stages, rather than single-point design solutions.

To this end, main propulsion subsystems were categorized into energy, power and thrust sources. Two types of matrices, namely, the property and interdependency matrices, were created to describe the relationships and power flows among these sources. These matrices were used to define various electrified propulsion architectures, including, but not limited to, turboelectric, series-parallel and distributed electric propulsion configurations.

As a case study, the matrices were used to generate and operate the distributed electric propulsion architecture of NASA’s X-57 Mod IV aircraft concept. The mission performance results were acceptably close to the data obtained from the literature. Finally, the matrices were used to simulate the changes in the operation strategy under two motor failure scenarios to demonstrate the ease of use, rapidness and automation.

It was seen that this new framework enables rapid and analysis-based comparisons among unconventional propulsion architectures where solutions are driven by requirements.

This article proposes a theoretical framework that synthesizes the main factors explaining the strategic contribution of communication department to open innovation (OI) processes. Because there is little or no research literature on communication and OI, the purpose is to fill this gap. A literature review and empirical qualitative research were conducted to weigh the significance of the framework in practice.

An interdisciplinary literature review was necessary to identify the main factors that explain the communication contribution to OI. The analysis of three multinational case studies has helped to enrich the proposed framework. Six semi-structured interviews were conducted with in-company communication managers and innovation managers in order to capture their perceptions.

Communication emerges as a strategic function with the potential to be embedded in the whole OI process. The main conclusion is that it may play an increasingly central role in enhancing relationships with external partners. Moreover, it enacts its strategic role while facilitating the enhancement of the organization's overall communication capability – that is, trust, transparency and a coherently articulated narrative.

This article has not been designed as a comprehensive overview of the topic, nor it is designed to be statistically representative or generalizable. The study was conducted with the intention of exploring the theoretical and practical contributions of communication department to OI, as well as to raise awareness among scholars and practitioners on this new but neglected topic for research. Its qualitative approach serves to assess the value of the framework proposed, and the key issues highlighted here require further research.

The theoretical framework proposed may enable innovation managers to identify the factors in which the communication function and its practitioners may play a role for facilitating OI processes. Likewise, communication practitioners may find it useful to foster their organizational role and capabilities within these processes.

This article underlines the significant contribution that the communication function may play in OI processes. Research on this topic has been neglected thus far, despite its significance for the competitiveness of companies and the economy as a whole.

The purpose of this paper is to review the current status of research on Wikidata and, in particular, of articles that either describe applications of Wikidata or provide empirical evidence, in order to uncover the topics of interest, the fields that are benefiting from its applications and which researchers and institutions are leading the work.

A systematic literature review is conducted to identify and review how Wikidata is being dealt with in academic research articles and the applications that are proposed. A rigorous and systematic process is implemented, aiming not only to summarize existing studies and research on the topic, but also to include an element of analytical criticism and a perspective on gaps and future research.

Despite Wikidata’s potential and the notable rise in research activity, the field is still in the early stages of study. Most research is published in conferences, highlighting such immaturity, and provides little empirical evidence of real use cases. Only a few disciplines currently benefit from Wikidata’s applications and do so with a significant gap between research and practice. Studies are dominated by European researchers, mirroring Wikidata’s content distribution and limiting its Worldwide applications.

The results collect and summarize existing Wikidata research articles published in the major international journals and conferences, delivering a meticulous summary of all the available empirical research on the topic which is representative of the state of the art at this time, complemented by a discussion of identified gaps and future work.

This paper reports on a quantitative study of data gathered from the Linked Open Vocabularies (LOV) catalogue, including the use of network analysis and metrics. The purpose of this paper is to gain insights into the structure of LOV and the use of vocabularies in the Web of Data. It is important to note that not all the vocabularies in it are registered in LOV. Given the de-centralised and collaborative nature of the use and adoption of these vocabularies, the results of the study can be used to identify emergent important vocabularies that are shaping the Web of Data.

The methodology is based on an analytical approach to a data set that captures a complete snapshot of the LOV catalogue dated April 2014. An initial analysis of the data is presented in order to obtain insights into the characteristics of the vocabularies found in LOV. This is followed by an analysis of the use of Vocabulary of a Friend properties that describe relations among vocabularies. Finally, the study is complemented with an analysis of the usage of the different vocabularies, and concludes by proposing a number of metrics.

The most relevant insight is that unsurprisingly the vocabularies with more presence are those used to model Semantic Web data, such as Resource Description Framework, RDF Schema and OWL, as well as broadly used standards as Simple Knowledge Organization System, DCTERMS and DCE. It was also discovered that the most used language is English and the vocabularies are not considered to be highly specialised in a field. Also, there is not a dominant scope of the vocabularies. Regarding the structural analysis, it is concluded that LOV is a heterogeneous network.

The paper provides an empirical analysis of the structure of LOV and the relations between its vocabularies, together with some metrics that may be of help to determine the important vocabularies from a practical perspective. The results are of interest for a better understanding of the evolution and dynamics of the Web of Data, and for applications that attempt to retrieve data in the Linked Data Cloud. These applications can benefit from the insights into the important vocabularies to be supported and the value added when mapping between and using the vocabularies.

This study aims to identify the main barriers and drivers that influence the role of communication in open innovation (OI) activities, and how these can support and enhance the innovative capacity of companies in the automotive industry. In order to get this, we carry out in an assembly plant of an automotive firm.

An action research study is carried out with the participation of the researchers, the Innovation and Communication managers of the assembly plant and four external stakeholders who have participated in OI dynamics carried out by the company.

It is observed that collaborative practices are integrated within the culture of the assembly plant. This is carried out according to the specific needs of the company, which limits the specificity of the stakeholders with which it collaborates. In terms of communication, the proposed functions are evidenced in practice. However, it is advisable to systematize these functions and to acquire, in the case of communication professionals, specific skills to support the integration of open practices.

Although studies exist that analyze OI in the automotive process, none have focused on how communication may help reinforce it. In addition, this study shows how communication may play a significant role in an assembly plant where research and development activities may not be important. Thus, the contribution of this study is twofold. On the one hand, it enriches the literature on OI; on the other hand, it proposes policies to improve the performance of OI practices by involving communication at all stages.

A gestão da inovação aberta (IA) sob uma perspectiva comunicativa tem sido um tema pouco estudado. Entretanto, estudos anteriores revelam que a comunicação poderia contribuir para a integração da dinâmica aberta, preparando as organizações para sua adoção. Por meio de um estudo realizado em uma montadora de veículos da indústria automotiva, temos por objetivo identificar as principais barreiras e os fatores determinantes que influenciam o papel da comunicação nas atividades de inovação aberta e como eles podem apoiar e melhorar a capacidade inovadora das empresas na indústria automotiva.

Um estudo de pesquisa-ação é realizado com a participação dos pesquisadores, dos gerentes de inovação e comunicação da montadora e representantes de quatro entidades externas que participaram da dinâmica de OI realizada pela empresa. As perspectivas destas partes interesadas sobre o papel que a comunicação tem e poderia ter na gestão da inovação na indústria nos permitem desenvolver uma nova proposta de comunicação com cinco funções comunicativas que poderão ajudar as empresas a lidar com os desafios da inovação aberta.

Observa-se que as práticas colaborativas estão integradas dentro da cultura organizacional da montadora. Em termos de colaboração, isto é realizado de acordo com as necessidades específicas da matriz, o que somado ao contexto da montadora limita o número e a especificidade das partes interessadas com as quais ela colabora. Em termos de comunicação, as funções propostas são evidenciadas na prática. Entretanto, é possível identificar a necessidade de formalizar e sistematizar estas funções e adquirir, no caso dos profissionais de comunicação, habilidades específicas para apoiar a integração de práticas abertas propostas pela IA.

Embora existam estudos que analisam a IA no processo automotivo, nenhum deles se concentrou em como a comunicação pode ajudar a reforçá-la. Além disso, mostramos como a comunicação pode desempenhar um papel significativo em uma montadora onde as atividades de pesquisa e desenvolvimento podem não ser importantes. Portanto, a contribuição deste estudo é dupla. Por um lado, enriquece a literatura sobre IA e, por outro lado, propõe políticas para melhorar o desempenho das práticas de IA, envolvendo a comunicação em todas as etapas.

Identificar las principales barreras y facilitadores que influyen en el papel de la comunicación en las actividades de innovación abierta en el contexto específico de una planta de ensamblaje en la industria de automoción.

Se lleva a cabo un estudio de investigación de acción, en el que investigadores y profesionales emprenden un proyecto en una planta de ensamblaje de automóviles. Ambos definen objetivos duales, y se describen las etapas de la metodología de investigación en acción. Dentro de este estudios, la recolección de información se realiza a través de entrevistas semiestructuradas.

Se observa que las prácticas colaborativas se integran dentro de la cultura de la planta ensambladora. Esto se lleva a cabo de acuerdo con las necesidades específicas de la empresa, lo que limita la especificidad de los grupos de interés con los que colabora. En términos de comunicación, las funciones propuestas se evidencian en la práctica. Sin embargo, es recomendable sistematizar estas funciones y adquirir, en el caso de los profesionales de la comunicación, habilidades específicas para apoyar la integración de prácticas abiertas.

Aunque existen estudios que analizan la IA en automoción, el doble análisis de la comunicación y la planta de ensamblaje es original dentro del ámbito de esta literatura. La creación de un marco de referencia propio para este contexto puede ayudar a las empresas a determinar los aspectos claves para que la IA tenga una mayor relevancia en este tipo de plantas. Cabe destacar también que la utilización de la metodología de investigación en acción aporta un valor añadido y originalidad, en cuanto que fomenta las relaciones colaborativas empresa-universidad.

This paper focusses on the tutoring process developed by three teachers during the implementation of two lesson studies (LSs) by students of the Bachelor of in Primary Education as a methodological strategy to facilitate the reconstruction of the teachers' practical knowledge.

The study is set within the framework of qualitative research and the methodology adopted is borne out by the case study.

The analysis shows how an adequate process of tutoring and accompaniment during the design, development and evaluation of the LS assists students to reconstruct their practical knowledge through action and to reflect on their actions and to develop key professional competences for initial teacher training.

This study was constrained by the need to develop a particular methodology of the study over a single four-month period, given that this type of process requires some quiet time for analysis and reflection. And the time that the tutors could make available due to the high ratio and the need to provide continuity to these processes to allow the students to consciously modify the tutors' lessons plans and incorporate this vision of being a teacher.

The paper advised to repeat the experience in successive courses, to accompany the students in order to analyse the educational value of LS and how educational value of LS affects the how the students reconstruct their practical knowledge.

This paper shows the strategies adopted to promote the reconstruction of practical knowledge in initial teacher training.

Because of the anisotropy of the process and the variability in the quality of printed parts, finite element analysis is not directly applicable to recycled materials manufactured using fused filament fabrication. The purpose of this study is to investigate the numerical-experimental mechanical behavior modeling of the recycled polymer, that is, recyclable polyethylene terephthalate (rPET), manufactured by a deposition FFF process under compressive stresses for new sustainable designs.

In all, 42 test specimens were manufactured and analyzed according to the ASTM D695-15 standards. Eight numerical analyzes were performed on a real design manufactured with rPET using Young's compression modulus from the experimental tests. Finally, eight additional experimental tests under uniaxial compression loads were performed on the real sustainable design for validating its mechanical behavior versus computational numerical tests.

As a result of the experimental tests, rPET behaves linearly until it reaches the elastic limit, along each manufacturing axis. The results of this study confirmed the design's structural safety by the load scenario and operating boundary conditions. Experimental and numerical results show a difference of 0.001–0.024 mm, allowing for the rPET to be configured as isotropic in numerical simulation software without having to modify its material modeling equations.

The results obtained are of great help to industry, designers and researchers because they validate the use of recycled rPET for the ecological production of real-sustainable products using MEX technology under compressive stress and its configuration for numerical simulations. Major design companies are now using recycled plastic materials in their high-end designs.

Validation results have been presented on test specimens and real items, comparing experimental material configuration values with numerical results. Specifically, to the best of the authors’ knowledge, no industrial or scientific work has been conducted with rPET subjected to uniaxial compression loads for characterizing experimentally and numerically the material using these results for validating a real case of a sustainable industrial product.

The purpose of this paper is to describe an attempt to provide a model for the description of the major aspects of historical interpersonal relationships between celebrities, with a focus on modelling different kinds of evidence about them, from documented and contrasted data to mere rumours.

The approach takes the form of analysis of cases and ontology engineering. A formal schema is provided for the model. The way information can be organized according to this is illustrated with examples about life facts and rumours regarding a popular Hollywood actress.

Some web systems that exploit the representation of personal relationships for purposes such as finding jobs or business opportunities have gained popularity recently. These systems enable users to take advantage of their personal information when combined with information provided by others who are willing to attain similar objectives. However, the importance of that kind of social information can also be applied to other fields in which the information is not directly provided by users, but comes from historical evidence or indirect sources. This is especially relevant to creating knowledge representations that attempt to reconstruct the social networks of celebrities or historical characters.

The model described in this paper can be used to gain insight regarding the historical course of their lives, and of their work relationships, as affected by personal ties. Further, the model could also be used to understand other culture‐bound issues or phenomena in the social sphere.
