Content Description on a Mobile Image Sharing Service: Hashtags on Instagram
The mobile social networking application Instagram is a well-known platform for sharing photos and videos. Since it is folksonomy-oriented, it provides the possibility for image indexing and knowledge representation through the assignment of hashtags to posted content. The purpose of this study is to analyze how Instagram users tag their pictures regarding different kinds of picture and hashtag categories. For such a content analysis, a distinction is made between Food, Pets, Selfies, Friends, Activity, Art, Fashion, Quotes (captioned photos), Landscape, and Architecture image categories as well as Content-relatedness (ofness, aboutness, and iconology), Emotiveness, Isness, Performativeness, Fakeness, "Insta"-Tags, and Sentences as hashtag categories. Altogether, 14,649 hashtags of 1,000 Instagram images were intellectually analyzed (100 pictures for each image category). Research questions are stated as follows: RQ1: Are there any differences in relative frequencies of hashtags in the picture categories? On average the number of hashtags per picture is 15. Lowest average values received the categories Selfie (average 10.9 tags per picture) and Friends (average 11.7 tags per picture); for highest, the categories Pet (average 18.6 tags), Fashion (average 17.6 tags), and Landscape (average 16.8 tags). RQ2: Given a picture category, what is the distribution of hashtag categories; and given a hashtag category, what is the distribution of picture categories? 60.20% of all hashtags were classified into the category Content-relatedness. Categories Emotiveness (about 4.38%) and Sentences (0.99%) were less often frequent. RQ3: Is there any association between image categories and hashtag categories? A statistically significant association between hashtag categories and image categories on Instagram exists, as a chi-square test of independence shows. This study enables a first broad overview on the tagging behavior of Instagram users and is not limited to a specific hashtag or picture motive, like previous studies
A Guide to Understanding & Using Folksonomies
In the digital landscape, social media and social platforms have become predominant communication tools in the wider context of Web 2.0. Folksonomies stem from user created metadata that popularized with the evolution of the world wide web in the late 1990s through link-focused websites called weblogs (Spiteri, 2006). Overtime metadata evolved to include tagging, also known as social tagging, hash tagging, and collaborative tagging (Ruslan, 2018). For the final project, I chose to focus on creating an instructional guide that introduced average social media users to the concept of folksonomies. The guide also touches on the specific characteristics of folksonomies (advantages and limitations), how folksonomies operate in the social media landscape, and the impacts folksonomies have on search behaviour in a social landscape
Linguistic, multimodal and cultural code-meshing: Exploring adolescentsâ language and literacy practices in social networking sites
This thesis will explore language and literacy practices in social networking sites (SNSs) that both draw on and expand beyond traditional principles of composition. Particularly, it will examine how adolescent participants are engaging with SNSs in ways that extend their learning and life opportunities beyond what is typically accessible in their rural province of Chiang Rai. Despite considerable research on language and literacy, there remains a limited body of research focused on adolescent literacy in Thailand and in rural contexts, such as Chiang Rai. There is also limited research in this area that provides a combined framework to account for the social, cultural, multimodal and linguistic repertoires of adolescents as materialised in their SNS practices.
This thesis will draw from sociolinguistic and sociocultural theories of Systemic Functional Linguistics (SFL) and intertextuality to analyse adolescent participantsâ linguistic and multimodal texts and how they shape and are shaped by a range of discourses in SNSs. However, both of these theories cannot provide a systematic account of adolescent participantsâ multimodal texts in depth. Therefore, this thesis will also draw from multimodality as an analytical framework to account for participantsâ multimodal texts (e.g., images, colours and layout).
As key findings will demonstrate, the complexity of participantsâ language and literacy practices in SNSs involves the blending of not only different languages and modes but also cultural resources (e.g., textual conventions and genres) â or what I refer to as linguistic, multimodal and cultural code-meshing practices. This study will set out a critical perspective on how such practices on SNSs are shaped by Chiang Rai adolescents to make new kinds of meanings, negotiate identities and relationships, and establish belongingness within both local and transnational SNS communities. Evidence from empirical data collected will include surveys and online observations

Searchable Signatures: Context and the Struggle for Recognition
Social networking sites made possible through Web 2.0 allow for unique user-generated tags called âsearchable signatures.â These tags move beyond the descriptive and act as means for users to assert online individual and group identities. This paper presents a study of searchable signatures on the Instagram application, demonstrating that these types of tags are valuable not only because they allow for both individuals and groups to engage in what social theorist Axel Honneth calls the âstruggle for recognition,â but also because they provide contextual use data and sociohistorical information so important to the understanding of digital objects. Methods for the gathering and display of searchable signatures in digital library environments are also explored
Captured and captioned: Representing family life on Instagram
This article examines how practices of family photography are being transformed
in the digital sphere, specifically on Instagram. While research on âdigital intimaciesâ
focusses on romantic or peer interactions, the digital practices of families â especially
intergenerational interactions â remain understudied. We use Janet Finchâs notion of
âfamily displayâ to consider how Instagram affords new modes of performing and sharing
family life. This concept has exciting potential for media-rich online spaces, but so far,
only a few studies examine how social media platforms extend the display of family
practices. To explore family photography on Instagram, we analyse a sample of 200
Instagram posts. We argue that features specific to photo-sharing in digital spaces,
such as hashtags, emojis and captions, open up new aspects of and audiences for family
display. Our analysis paves the way for future research about how relationships are
displayed across a range of digital platforms.info:eu-repo/semantics/publishedVersio
Learning to Hash-tag Videos with Tag2Vec
User-given tags or labels are valuable resources for semantic understanding
of visual media such as images and videos. Recently, a new type of labeling
mechanism known as hash-tags have become increasingly popular on social media
sites. In this paper, we study the problem of generating relevant and useful
hash-tags for short video clips. Traditional data-driven approaches for tag
enrichment and recommendation use direct visual similarity for label transfer
and propagation. We attempt to learn a direct low-cost mapping from video to
hash-tags using a two step training process. We first employ a natural language
processing (NLP) technique, skip-gram models with neural network training to
learn a low-dimensional vector representation of hash-tags (Tag2Vec) using a
corpus of 10 million hash-tags. We then train an embedding function to map
video features to the low-dimensional Tag2vec space. We learn this embedding
for 29 categories of short video clips with hash-tags. A query video without
any tag-information can then be directly mapped to the vector space of tags
using the learned embedding and relevant tags can be found by performing a
simple nearest-neighbor retrieval in the Tag2Vec space. We validate the
relevance of the tags suggested by our system qualitatively and quantitatively
with a user study
Hashtags on Instagram: Self-created or Mediated by Best Practices and Tools?
Social media enables conversations mediated through documents as texts, audio, images, or videos. Likewise, hashtags became an essential medium for social media communication. Instagram is well-known as one of the current platforms for hashtagging. This exploratory study investigates how hashtags used on Instagram became established in respect of self-creation and best practices or tools. The analysis is based on data obtained from an online survey (N = 1,006) of Instagram users. 55.7% of the respondents use hashtags on Instagram. Only self-created hashtags are assigned by 41.4%, whereas 58.6% are (sometimes) inspired by others. Best practices and tools based on friends/other users or Instagram functions are more frequently used in contrast to offers from influencers or third-parties (e.g. guides, hashtag-sets). Furthermore, the majority does not intentionally use false hashtags. This study enables a first overview of the Instagram usersâ hashtagging creation behavior and selection process
Scalable Privacy-Compliant Virality Prediction on Twitter
The digital town hall of Twitter becomes a preferred medium of communication
for individuals and organizations across the globe. Some of them reach
audiences of millions, while others struggle to get noticed. Given the impact
of social media, the question remains more relevant than ever: how to model the
dynamics of attention in Twitter. Researchers around the world turn to machine
learning to predict the most influential tweets and authors, navigating the
volume, velocity, and variety of social big data, with many compromises. In
this paper, we revisit content popularity prediction on Twitter. We argue that
strict alignment of data acquisition, storage and analysis algorithms is
necessary to avoid the common trade-offs between scalability, accuracy and
privacy compliance. We propose a new framework for the rapid acquisition of
large-scale datasets, high accuracy supervisory signal and multilanguage
sentiment prediction while respecting every privacy request applicable. We then
apply a novel gradient boosting framework to achieve state-of-the-art results
in virality ranking, already before including tweet's visual or propagation
features. Our Gradient Boosted Regression Tree is the first to offer
explainable, strong ranking performance on benchmark datasets. Since the
analysis focused on features available early, the model is immediately
applicable to incoming tweets in 18 languages.Comment: AffCon@AAAI-19 Best Paper Award; Presented at AAAI-19 W1: Affective
