Time Aware Knowledge Extraction for Microblog Summarization on Twitter

Microblogging services like Twitter and Facebook collect millions of user generated content every moment about trending news, occurring events, and so on. Nevertheless, it is really a nightmare to find information of interest through the huge amount of available posts that are often noise and redundant. In general, social media analytics services have caught increasing attention from both side research and industry. Specifically, the dynamic context of microblogging requires to manage not only meaning of information but also the evolution of knowledge over the timeline. This work defines Time Aware Knowledge Extraction (briefly TAKE) methodology that relies on temporal extension of Fuzzy Formal Concept Analysis. In particular, a microblog summarization algorithm has been defined filtering the concepts organized by TAKE in a time-dependent hierarchy. The algorithm addresses topic-based summarization on Twitter. Besides considering the timing of the concepts, another distinguish feature of the proposed microblog summarization framework is the possibility to have more or less detailed summary, according to the user's needs, with good levels of quality and completeness as highlighted in the experimental results.Comment: 33 pages, 10 figure

Big data and social media: A scientometrics analysis

The purpose of this research is to investigate the status and the evolution of the scientific studies for the effect of social networks on big data and usage of big data for modeling the social net-works users’ behavior. This paper presents a comprehensive review of the studies associated with big data in social media. The study uses Scopus database as a primary search engine and covers 2000 of highly cited articles over the period 2012-2019. The records are statistically analyzed and categorized in terms of different criteria. The findings show that researches have grown exponentially since 2014 and the trend has continued at relatively stable rates. Based on the survey, decision support systems is the keyword which has carried the highest densities followed by heuristics methods. Among the most cited articles, papers published by researchers in United States have received the highest citations (7548), followed by United Kingdom (588) and China with 543 citations. Thematic analysis shows that the subject nearly maintained an important and well-developed research field and for better results we can merge our research with “big data analytics” and “twitter” that are important topics in this field but not developed well

Benefits of using data mining techniques to extract and analyze Twitter data for higher education applications: a systematic literature review

En los últimos años, existe un creciente interés por los actores de la educación en la inclusión de las TIC en sus instituciones, como es el caso de las redes sociales, que lejos de ser un problema y mediante un uso guiado de las mismas, permiten innovar las sesiones de clases tradicionales y mejorar la comunicación entre docentes y estudiantes. En el presente estudio se plantearon dos objetivos: (1) realizar una revisión sistemática de la literatura, mediante la búsqueda de artículos publicados entre enero/2007 y marzo/2019, en bases de datos como ACM, IEEE, ScienceDirect, Springer, entre otras, para identificar las investigaciones que han aplicado técnicas de minería de datos, para la extracción y análisis de datos de Twitter en la educación superior; y, (2) destacar las prácticas pedagógicas que han incorporado Twitter y minería de datos para mejorar los procesos educativos. De los 315 artículos obtenidos, fueron seleccionados 65 que cumplieron con los criterios de inclusión. Los principales resultados indican que: (1) las técnicas de minería de datos más utilizadas son predictivas con tareas de clasificación; (2) Twitter se usa principalmente para: (a) determinar percepción estudiantil; (b) compartir información, material y recursos; (c) generar comunicación y participación; (d) fomentar habilidades; y (e) mejorar la expresión oral y el rendimiento académico; (3) Estados Unidos es el país con mayor número de trabajos; sin embargo, en países de Latinoamérica los hallazgos son pocos, por lo que se apertura un campo de investigación en esta región; y (4) los estudios incluyeron modelos, métodos, estrategias, teorías o instrumentos como práctica pedagógica; de modo que no existe un consenso en la forma en que los datos extraídos de Twitter podrían ser incorporados en la educación superior para mejorar los procesos de enseñanza y aprendizaje.In recent years, there has been a growing interest by education actors to include TIC in their institutions; as well as social networks, far from being a problem and their use aimed, permit innovate traditional classes and improve communication between teachers and students This study has two objectives: (1) conduct a systematic literature review through searching papers published between January/2007 and March/2019 in data bases like as ACM, IEEE, ScienceDirect, Springer and others, to evidence researches that apply data mining techniques to extract and analyze Twitters data in higher education; and (2) to emphasize pedagogic practices that include Twitter and data mining to improve education process. From 315 papers obtained, only 65 fulfilled inclusion criteria. The main results indicate that: (1) the most used data mining techniques are predictive with classification tasks; (2) Twitter is principally used to: (a) determinate perception; (b) share information, materials and resources; (c) generate communication and participation; (d) promote abilities and (e) improve oral expression and academic performance; (3) United States has the most numbers of researches in this area; however, in Latin-American countries findings are not enough, so, there a new area to investigate in this region and (4) researches used models, methods, strategies, theories and instruments as a pedagogic practice; so that, there wasn’t an agreement about a shape to include Twitter data extracting in higher education to improve teaching and learning process.Instituto de Investigación en Informátic
