Janna Joceli C. de Omena is a PhD candidate who aims to conduct exploratory studies on connecting practices using digital methods and design social media research techniques. Their research focuses on three main areas: the politics of platforms, social media technicity, and digital objects as constitutive elements of platforms. They plan to apply theoretical, technical, and practical studies of social media platforms through case studies in fields like journalism, digital activism, and pop culture using tools from DMI Tools and MEDIALAB. The research group seeks members willing to learn digital methods and interested in platform studies to help with independent research, teamwork, and improving data-driven analysis through data sprints, a wiki, and publications.

To Thread or Not to Thread: The Impact of Conversation Threading on Online Di...Pablo Aragón
Online discussion is essential for the communication and collaboration of online communities. The reciprocal exchange of messages between users that characterizes online discussion can be represented in many different ways. While some platforms display messages chronologically using a simple linear interface, others use a hierarchical (threaded) interface to represent more explicitly the structure of the discussion. Although the type of representation has been shown to affect communication, to the best of our knowledge, the impact of using either one or the other has not yet been investigated in a large and mature online community.
In this work we analyze Menéame, a popular Spanish social news platform which recently transitioned from a linear to a hierarchical interface, becoming an ideal research opportunity for this purpose. Using interrupted time series analysis and regression discontinuity design, we observe an abrupt and significant increase in social reciprocity after the adoption of a threaded interface. We furthermore extend state-ofthe-art generative models of discussion threads by including reciprocity, a fundamental feature to explain better the structure of the discussions, both before and after the change in the interface.

A comparative study of bloggers linking to professional and participatory media. Do bloggers refer to a broad range of viewpoints and do they evaluate and comment on linked material? Through a combined content and network analysis of 323 blogs, this study reveals that bloggers primarily give attention to a small selection of articles on a given topical basis.
Sampling of User Behavior Using Online Social NetworkEditor IJCATR
The popularity of online networks provides an opportunity to study the characteristics of online social network graphs is important, both to improve current systems and to design new application of online social networks. Although personalized search has been proposed for many years and many personalization strategies have been investigated, it is still unclear whether personalization is consistently effective on different queries for different users, and under different search contexts. In this paper, we study performance of information collection in a dynamic social network. By analyzing the results, we reveal that personalized search has significant improvement over common web search.
The mixing time of thee sampling process strongly depends on the characteristics of the graph.

Optimistic interpretations: ignoring social relations that influence the social distribution and impact of the new ICT. The new digital technologies function as commodities, and their distribution – at least initially – tends to follow existing divisions of class, race and gender. Rather than assisting with equalization, the new information and communication technologies tend to reinforce social inequality, and lead to the formation of socially and technologically disadvantaged and excluded individuals (Golding, 1996; Zappala, 2000).

BigFoot Digital: Dramaturgical self and content marketing strategyMelissa Hoover
In an era where online users share and disseminate public content, a 'digital' dramaturgical self image is being built and stored. The question arising from this is, who or what is building our digital dramaturgical self? Furthermore, are users even aware of having another builder involved in shaping the image of their digital dramaturgical self? The methodological approach will include a website remodelling, plugin installation—with the specific purpose of increasing audience conversation—setting up a content marketing strategy, social media engagement and collaboration efforts, and Web 2.0 digital sphere visibility. Projects such as Bigfoot Digital Footprint aim to increase audience awareness, but more so, to encourage audience engagement in PEST (Public Engagement with Science Technology) science communication and creation.

Title: Computational Social Science – what is it and what can(‘t) it do?
What is your talk about?
In Computational Social Science (CSS) we use computer science algorithms to analyse qualitative data at scale. In this talk I define CSS, describe what the opportunities and barriers are in using such methods, and give examples from published research, for example on analysing thousands of Ofsted documents.
What are the key messages of your talk?
The use of CSS methods makes it is possible to analyse some data sources at scale that previously would be unrealistic to analyse ‘by hand’.
What are the implications for practice or research from your talk?
CSS allows both more qualitative and more quantitative researchers to analyse unstructured data sources at scale.

Workshop facilitators: Janna Joceli Omena, Beatrice Gobbo
Abstract:
This workshop offers methodological guidance for narrating networks through visual network analysis (VNA) (Venturini et al. 2021) and a technicity perspective to the practice of digital methods (Omena 2021). It is divided into two parts. First, we will introduce what questions we should ask to make sense of network building and the key principles of VNA. Second, students will work on digital and printed recommendation networks aiming at narrating what they see.
Main takeaways
Students will be able to explore and identify the main components of a digital network
Students will reflect on the distinction between what is network exploration (description tasks) and network narration (insights, findings)
Students will develop the ability to tell a story about the topic under investigation and what constitutes the network.

As Universidades Portuguesas no Facebook - Análise de Redes e Comunicação de Ciência
António Granado
Janna Joceli C. de Omena
Como é que as universidades portuguesas fazem uso da rede social Facebook? O quê e como comunicam? Como é que as plataformas digitais servem de ferramenta/ponte para a comunicação de ciência? Qual o contributo da análise visual de redes neste processo? Estas foram as questões-chave que nos conduziram ao presente mapeamento das principais universidades portuguesas no Facebook, a partir de um estudo guiado pela perspetiva dos Métodos Digitais (Rogers, 2013) e de Análise Visual de Redes (Venturini et.al., 2015). O nosso objetivo é apresentar os primeiros resultados obtidos, com base na investigação exploratória que se debruçou sobre duas áreas distintas, mas complementares. Em Março de 2017, com a ajuda da aplicação Netvizz, foram coletados dados das 15 universidades representadas no Conselho de Reitores das Universidades Portuguesas (CRUP). Os dados recolhidos incluíram páginas (todos os posts e interações registadas desde a criação de cada página), imagens da linha do tempo (timeline), e pagelike network. A análise visual de redes permite-nos concluir sobre os principais atores da rede e as suas conexões, assim como autoridade e influência. Para além disto, a análise de clusters possibilita perceber os micro-sistemas de interesse de cada uma das universidades. Após esta primeira análise, selecionámos os posts efetuados pelas 15 universidades durante o ano de 2016 (N=7103), no sentido de obter uma primeira impressão sobre o tipo de conteúdo que estas instituições partilham no Facebook. Os posts foram classificados segundo as 11 categorias propostas por Dumouchel (2014) na sua análise das páginas de Facebook das universidades da Florida (EUA). Deste trabalho, retiramos conclusões iniciais sobre frequência, temas e tipos de conteúdos partilhados pelas universidades portuguesas no Facebook.
