Communication Research field has an extraordinary growth pattern, indeed bigger than other research fields. In order to extract knowledge from such amount, intelligent techniques are needed. In such a way, using bibliometric techniques, the evolution of the conceptual, social and intellectual aspects of this research field could be analysed, and hence, understood. Although the communication research field has been widely analysed using bibliometric techniques and science mapping tools, a conceptual analysis of the whole communication research field is still needed. Therefore, this article introduces the first science mapping analysis in the communication research field based on the Web of Science Subject Category "Communication," showing its conceptual structure and scientific evolution. SciMAT, a bibliometric science mapping software tool based on co-word analysis and h-index, is applied using a sample of 33.627 research documents from 1980 to 2013 published in 74 main communication journals indexed in the Journal Citation Reports of the Web of Science. The results show that research conducted in the communication research is concentrated on the following sixteen disconnected thematic areas: “children”, “psychological aspects”, “news”, “audience”, “surveys”, “advertising”, “health”, “relationship”, “gender”, “discourse”, “telephone communication”, “public relation”, “telecommunications”, “public opinion”, “activism” and “internet”. These areas have progressively disconnected among them, which drives to a Communication field relatively fragmented. El campo científico de la comunicación ha experimentado un enorme crecimiento a lo largo de los años, superando incluso a algunas áreas científicas consagradas. Mediante el uso de técnicas bibliométricas, podemos analizar la evolución conceptual, social e intelectual de esta área, así como comprenderla. En particular, el área de «Comunicación» ha sido ampliamente estudiada desde un punto de vista bibliométrico, pero no se ha realizado un análisis conceptual global del área englobado en un marco longitudinal. En este sentido, este artículo muestra el primer análisis de mapas científicos del área de investigación de la comunicación basándose en la Categoría de la Web of Science «Communication», centrándose en la estructura conceptual y cómo esta ha evolucionado. El estudio se ha realizado mediante la herramienta de análisis de mapas científicos SciMAT, basada en los mapas de co-palabras y en el índice-h. Un conjunto de 33.627 artículos científicos, publicados entre 1980 y 2013 en las 74 principales revistas del Journal Citation Reports de la Web of Science, han sido estudiados. Analizando los resultados, podemos destacar que la investigación llevada a cabo en el área de la comunicación se ha centrado en dieciséis áreas temáticas: «infancia», «aspectos psicológicos», «noticias», «audiencias», «sondeos», «publicidad», «salud», «relaciones», «género», «discurso», «comunicación telefónica», «relaciones públicas», «telecomunicaciones», «opinión pública», «activismo» e «Internet». Estas áreas se han desconectado entre ellas progresivamente, lo que conduce a un campo relativamente fragmentado.

Applied Intelligence is one of the most important international scientific journals in the field of artificial intelligence. From 1991, Applied Intelligence has been oriented to support research advances in new and innovative intelligent systems, methodologies, and their applications in solving real-life complex problems. In this way, Applied Intelligence hosts more than 2,400 publications and achieves around 31,800 citations. Moreover, Applied Intelligence is recognized by the industrial, academic, and scientific communities as a source of the latest innovative and advanced solutions in intelligent manufacturing, privacy-preserving systems, risk analysis, knowledge-based management, modern techniques to improve healthcare systems, methods to assist government, and solving industrial problems that are too complex to be solved through conventional approaches. Bearing in mind that Applied Intelligence celebrates its 30th anniversary in 2021, it is appropriate to analyze its bibliometric performance, conceptual structure, and thematic evolution. To do that, this paper conducts a bibliometric performance and conceptual structure analysis of Applied Intelligence from 1991 to 2020 using SciMAT. Firstly, the performance of the journal is analyzed according to the data retrieved from Scopus, putting the focus on the productivity of the authors, citations, countries, organizations, funding agencies, and most relevant publications. Finally, the conceptual structure of the journal is analyzed with the bibliometric software tool SciMAT, identifying the main thematic areas that have been the object of research and their composition, relationship, and evolution during the period analyzed.

One of the variables assessed in the research related to the consumption of green products is environmental concern. This work explores a new dimension to environmental concern: biodiversity. The reasons why research has focused on the mentioned dimension are, on one hand, the consideration of biodiversity as the main environmental indicator of the sustainability and, on the other, the paucity of marketing studies analyzing this variable and its relationship with the purchase behavior of sustainable products. The present paper proposes a classification of sustainable consumers according to their level of biodiversity concern. It is based on a quantitative study on the consumption behavior of olive oils carried out in four European countries, using the clustering multivariate technique. The results point out that there are differences between the segments depending on their level of commitment to biodiversity. The country’s influence on the way that its people experience biodiversity was also tackled. As a main conclusion, we identify four clusters or segments (not concerned, passive, active and influencers), setting up a multilevel structure of ascending intensity with regard to their level of biodiversity concern, with differences in the composition according to age and sex between countries.

Amidst the public’s growing preoccupation with healthy eating, both inside and outside the home; an increase in people eating out; and the importance that olive oil has acquired in the markets due to its health benefits, the aim of this study is to find out whether health is also a relevant criterion for chefs in their olive oil purchase decisions. To this end, a survey was conducted of 400 chefs in Spain belonging to the international chefs’ association Euro-Toques. The results show that only 2% of the sample consider health to be a relevant criterion in the purchase of olive oils and that the attribute of “health” is not used by restaurants as an element of differentiation by which to position themselves in the market. These results lead us to conclude that the consumer demand for healthy foods (in this case, olive oils) is not being met by the restaurant sector. Moreover, this raises the question as to whether chefs actually make good opinion leaders, with all that this social role implies.
