Theoretical foundations and limits of word embeddings: What types of meaning can they capture?

Measuring meaning is a central problem in cultural sociology and word embeddings may offer powerful new tools to do so. But like any tool, they build on and exert theoretical assumptions. In this paper I theorize the ways in which word embeddings model three core premises of a structural linguistic theory of meaning: that meaning is coherent, relational, and may be analyzed as a static system.

Machine Learning as a Model for Cultural Learning: Teaching an Algorithm What it Means to be Fat.

Public culture is a powerful source of cognitive socialization; for example, media language is full of meanings about body weight. Yet it remains unclear how individuals process meanings in public culture. We suggest that schema learning is a core mechanism by which public culture becomes personal culture.

#Proana: Pro-Eating Disorder Socialization on Twitter.

Purpose: Pro-eating disorder (ED) online movements support engagement with ED lifestyles and are associated with negative health consequences for adolescents with EDs. Twitter is a popular social media site among adolescents that provides a unique setting for Pro-ED content to be publicly exchanged. The purpose of this study was to investigate Pro-ED Twitter profiles' references to EDs and how their social connections (followers) reference EDs.

Evaluating College Students' Displayed Alcohol References on Facebook and Twitter.

Purpose: Current trends suggest that adolescents and young adults typically maintain a social media "portfolio" of several sites including Facebook and Twitter, but little is known regarding how an individual chooses to display risk behaviors across these different sites. The purpose of this study was to investigate college students' displayed alcohol references on both Facebook and Twitter.

Methods: Among a larger sample of college students from two universities, we identified participants who maintained both Facebook and Twitter profiles.

Using A Facebook Group As An Adjunct To A Pilot mHealth Physical Activity Intervention: A Mixed Methods Approach.

In the United States, most adolescents do not obtain the recommended amounts of physical activity for optimal health. Around 80% of adolescents own a mobile device, and social media is frequently used by adolescents on mobile devices. Few studies have examined the use of social media as part of an intervention to promote physical activity.
