World Influence of Infectious Diseases from Wikipedia Network Analysis
2019
AbstractWe consider the network of 5 416 537 articles of English Wikipedia extracted in 2017. Using the recent reduced Google matrix (REGOMAX) method we construct the reduced network of 230 articles (nodes) of infectious diseases and 195 articles of world countries. This method generates the reduced directed network between all 425 nodes taking into account all direct and indirect links with pathways via the huge global network. PageRank and CheiRank algorithms are used to determine the most influential diseases with the top PageRank diseases being Tuberculosis, HIV/AIDS and Malaria. From the reduced Google matrix we determine the sensitivity of world countries to specific diseases integrat…
Novel Version of PageRank, CheiRank and 2DRank for Wikipedia in Multilingual Network Using Social Impact
2020
International audience; Nowadays, information describing navigation behaviour of internet users are used in several fields, e-commerce, economy, sociology and data science. Such information can be extracted from different knowledge bases, including business-oriented ones. In this paper, we propose a new model for the PageRank, CheiRank and 2DRank algorithm based on the use of clickstream and pageviews data in the google matrix construction. We used data from Wikipedia and analysed links between over 20 million articles from 11 language editions. We extracted over 1.4 billion source-destination pairs of articles from SQL dumps and more than 700 million pairs from XML dumps. Additionally, we …
La transición española : ¿qué sabe el alumnado de 1º de bachillerato?
2020
El presente artículo es el resultado del análisis de una encuesta realizada a 79 estudiantes de 1º de Bachillerato sobre la transición española. Mediante esta investigación se quiere acreditar, con metodología cuantitativa, los conocimientos e ideas que el alumnado encuestado tiene acerca de ese periodo histórico tras la realización de la Educación Secundaria. Para ello se ha realizado una encuesta con variedad de preguntas entre las cuales se han incluido algunas relacionadas entre sí para comprobar posibles contradicciones en las respuestas. La encuesta abarca diferentes cuestiones: desde personajes históricos hasta actores más globales como diferentes organizaciones o movilizaciones soci…
Beyond the “ivory tower”. Comparing academic and non-academic knowledge on social entrepreneurship
2021
The increasing relevance of societal challenges has recently brought social entrepreneurship to the fore due to its capacity to leverage entrepreneurial processes to achieve social value while ensuring profits. In this study, we apply an experimental research method to analyse the concept of social entrepreneurship comprehensively. More specifically, we develop bibliometric analysis and web crawling techniques to gather information related to social entrepreneurship from Scopus and Wikipedia. We conduct a comparative network analysis of social entrepreneurship’s conceptual structure at academic and non-academic levels. This analysis has been performed considering scientific articles’ keywor…

Wikipedia network analysis of cancer interactions and world influence
2019
AbstractWe apply the Google matrix algorithms for analysis of interactions and influence of 37 cancer types, 203 cancer drugs and 195 world countries using the network of 5 416 537 English Wikipedia articles with all their directed hyperlinks. The PageRank algorithm provides the importance order of cancers which has 60% and 70% overlaps with the top 10 cancers extracted from World Health Organization GLOBOCAN 2018 and Global Burden of Diseases Study 2017, respectively. The recently developed reduced Google matrix algorithm gives networks of interactions between cancers, drugs and countries taking into account all direct and indirect links between these selected 435 entities. These reduced n…
Semantic sense extraction from Wikipedia pages
2010
This paper presents a technique aimed to extract structured information from unstructured Wikipedia contents related to a particular topic, and to arrange it in a semantic way inside an ontology. The general framework is the design of an artificial agent able to deliberate when increasing its domain knowledge. In particular, this cognitive agent acts as a dialogue manager in an Intelligent Tutoring System (ITS) already presented by the authors. Our approach is based on the definition of useful patterns able to extract and identify novel concepts and relations to be added to the knowledge base. We propose a method that uses information from the wiki page’s structure. We define different stra…
Who cares about calling non-consensual sex "rape" in summaries of fictional narratives on Wikipedia? From a gender identity hypothesis to recurrent a…
2021
International audience; This presentation is based on a larger research project about novel and film summaries on Wikipedia where a recurrent dissensus as to which word summarizes best what happens in a fictional sex scene (typically seduction vs rape) was spotted by exporting and searching revision histories. The linguistic consistency and recurrence of such words shifts suggests these findings cannot be explained solely by interindividual subjective variation in interpretation and chance : can we predict whether a reader / contributor will make this type of discursive shift on the basis of their social identity, such as their gender ? A methodological difficulty is that identity online an…
Wikipedia-artikkeli tekstilajina : koheesion keinot tekstin rakentajina
2015
Tässä tutkimuksessa tarkastelin suomenkielisiä Wikipedia-artikkeleita tekstilajin näkökulmasta. Wikipedia on nykyisin erittäin merkittävä tiedonhaun väline. Se sisältää valtavan määrän yhteis-toiminnallisesti tuotettua tietoa ja poikkeaa kustannetuista tietosanakirjoista monin tavoin. Wik-pedialle on leimallista, että kaikki voivat vapaasti osallistua sen artikkelien kirjoittamiseen ja muokkaamiseen. Tutkimukseni teoreettisena viitekehyksenä toimi systeemis-funktionaalinen teoria. Pohjasin analyysini erityisesti M. A. K. Hallidayn ajatuksiin systeemis-funktionaalisesta tekstilajitutki-muksesta. Siinä kieltä tulkitaan sosio-kulttuurisessa kontekstissa. Teorian perusyksikkö on teks-ti: kieltä…
