This paper proposes probabilistic models for social media mining based on the multiple attributes of social media content, bloggers, and links. The authors present a unique social media classification framework that computes the normalized document-topic matrix. After comparing the results for social media classification on real-world data, the authors find that the model outperforms the other techniques in terms of overall precision and recall. The results demonstrate that additional information contained in social media attributes can improve classification and retrieval results.

This paper examines the potential role of social media in enhancing the understanding and perception of victims of police killings and the data collection surrounding these incidents. Through a series of content analysis and social media mining exercises, the authors observe the emergence of three distinct types of social media content offered on victims of police killings: persistence of the deceased’s activity across social media, sensational commentary on videos and blog postings, and memorials on Facebook, Twitter, and Tumblr. As part of a larger investigation of the availability and accessibility of official police homicide data, this paper aims to present social media data as a potentially powerful source of information to supplement quantitative reports. This process may be especially useful for the most affected communities, particularly BIPOC communities.

La crisis sanitaria de la covid-19 vino acompañada de medidas de aislamiento, entre las que se encontraba el confinamiento domiciliario, que provocaron múltiples reacciones en las redes sociales. El objetivo de este artículo consiste en analizar la conversación digital observada en Twitter®, en torno al hashtag #MeQuedoEnCasa, en el periodo comprendido entre el 20 y el 27 de marzo de 2020. El estudio parte de una metodología mixta, en la que se combinan técnicas de análisis del social media mining con estrategias cualitativas propias del análisis lingüístico. Desde el punto de vista teórico, nos apoyamos en conceptos de las teorías del encuadre y de la valoración. Los resultados apuntan al enmarque positivo del confinamiento, a través de rasgos semióticos de distinto nivel: léxico, semántico y pragmático. Las cuentas más influyentes inclinaron su producción discursiva hacia la polaridad positiva. El análisis empírico permite concluir que el encuadre discursivo de esta conversación digital combina dos ejes semánticos (colectividad y salud), dos ejes enunciativos (aquí y ahora) y un eje emocional, lo que implica que hashtags como #MeQuedoEnCasa funcionan como señas de identidad social, como marcas de anclaje enunciativo y como instrumentos para fomentar la responsabilidad del individuo desde valores positivos.
