methodology

We can define it as a problem solving applied to research questions

One methodology, many methods (or tecniques)

Sociological research in social media: the qualitative/quantitative debate is very difficult to apply

Reasons1. Social media are software objects/texts2. Difficulties in applying the concept of representativeness3. Digital texts are performative activities4. Digital texts are culturally embedded

methodology

Three great models of social research in participative web

1. EthnographyInterpretative approachText as unit of analysis

2. StatisticalMathematical approachQuantification/metrics as unit of analysis

3. ComputationalComputer science approachFormal relationship and unit of analysis

YoutubeVideosharing platform: different use, different metrics

Audience interaction1. visualizations (videos)2. visualizations (channells)

Social interaction1. comments2. I like/I don't like3. friending/subscriptions

Platform interaction1. metadata (tag, video title, ID video, contributor, date added, description)

YoutubeEthnographic research

StrategiesVideos as significative objectUse in small communities (e.g. vloggers)

Research characteristicsSmall size of videos analizedGreat use of different qualitative tecniques (e.g interviews, audio transcriptions)Multi-methods/triangulation approaches preferred

Facebookmeta-information/sampling with Facebook

Facebook could also be used to disseminate a survey. By leveraging on Facebook advertising platform it could be possible to target the survey to specific segment of population in order to create representative sample of Facebook population (structured by gender, age and any other kind of information available in the platform). Moreover this strategy could complement the once based on Facebook App. Administering a survey via Facebook App will enable researchers to get both answers and data (age, gender, likes and other structural variables).

Twitterrelevant aspects:

•Network Structure Studies: friends/follower/hubs etc.

•Users activities: messages/reTweets/@reply

•Users social practices•Emergent phenomena:

Elections, Natural disasters, Crisis communication

•Case studies (Journalism)

What you can get:- Public stream- Search API- Streaming API- Firehose data

Page 37: Il laboratorio aperto: limiti e possibilità dell’uso di Facebook, Twitter e YouTube come sorgente dati

TwitterResearchers largely used (and still use) Twitter search or streaming API.

Is the sample good enough?(Morstatter et al. 2013)

- When the number of tweets monitored increase the reliability of streaming solution decrease. - Streaming API data estimates top n hashtag when n is large but fails when n is small.- Streaming API return almost the complete set of geotagged tweets

TwitterTwitter research started within the traditional approach of network studies from a computer science perspective (Java, A. et al., 2007) and was soon followed by many researches aiming at giving a general description of the phenomenon (Huberman, B.A., Romero, D.M. & Wu, F., 2009.). The public-by-default nature of Twitter led toward a massive adoption of computational methods: data were simple, textual, and easy accessible.

Page 40: Il laboratorio aperto: limiti e possibilità dell’uso di Facebook, Twitter e YouTube come sorgente dati

TwitterIn few years researchers started to focus on the social aspects of Twitter based interactions (Marwick, A.E. & boyd, d., 2010) and on the Twitter based emergent phenomena (Earle, P., 2010)

< Who do you tweet *to*?> No one & I love that. Or maybe myself five min. ago: I write the tweets I want to read.

I don’t tweet to anybody; I just do it to do i

Page 41: Il laboratorio aperto: limiti e possibilità dell’uso di Facebook, Twitter e YouTube come sorgente dati

TwitterIn 2011 the was a peak of interest in Twitter based research both in social sciences and in computer sciences on the following directions:- Automated analysis / event detection (Hong, L. & Davison, B.D., 2011 - Welch, M.J. et al., 2011. - Weng, J. & Lee, B.-sung, 2011)

- Events monitor and analysis (Bruns, A., 2011, Bruns, A. & Burgess, J., 2011, Rossi, L., Magnani, M. & Iadarola).- Specific case studies (Lasorsa, D., Lewis, S. & Holton, A., 2011.)

anobiiSingle research (Aiello, L.M. et al., 2012) on link creation:

creation on social ties is strongly driven by:- homophily and proximity (language, similarity of interests, geographic proximity).

Data available upon request:- user's profile- library information- groups affiliations
