vosonSML

vosonSML is an R package that provides a suite of tools for collecting and constructing networks from social media data. It provides easy-to-use functions for collecting data across popular platforms and generating different types of networks for analysis.

vosonSML is the SocialMediaLab package, renamed. We decided that SocialMediaLab was a bit too generic and also we wanted to indicate the connection to the Virtual Observatory for the Study of Online Networks Lab, where this package was conceived and created.

vosonSML was created by Timothy Graham and Robert Ackland, with major contributions by Chung-hong Chan and Bryan Gertzel.

Supported Social Media

vosonSML currently features the collection of data and generation of networks from twitter, youtube and reddit.

Unfortunately we are no longer able to maintain facebook and instagram collection, however these features will still be available in releases prior to version 0.25.0.

Installation

Install the current version from Github:

# github installation requires the 'devtools' or 'remotes' package
library(devtools)

# optionally add the parameter 'dependencies = TRUE' to install package dependencies
devtools::install_github("vosonlab/vosonSML")

Install vosonSML from CRAN:

install.packages("vosonSML", dependencies = TRUE)

Note about previous releases: The vosonSML package was previously in a subdirectory, so if you wish to install versions prior to 0.26 please remember to include the subdir parameter.

devtools::install_github("vosonlab/vosonSML@v0.25.0", subdir = "vosonSML")

Getting started

The following usage examples will provide a great introduction to using vosonSML. There are also several "how to" guides, including an "Absolute Beginners Guide to vosonSML" tutorial aimed at people with little or no programming experience on the vosonSML page of the VOSON website.

Usage

The process of authentication, data collection and creating social network in vosonSML is expressed with the three verb functions: Authenticate, Collect and Create. The following are some examples:

Twitter Examples

library(magrittr)
library(vosonSML)

# Authenticate with twitter, Collect 100 tweets for the '#auspol' hashtag and Create an actor and 
# semantic network
myKeys <- list(appName = "vosonSML", apiKey = "xxxxxxxxxxxx", apiSecret = "xxxxxxxxxxxx", 
               accessToken = "xxxxxxxxxxxx", accessTokenSecret = "xxxxxxxxxxxx")
  
twitterAuth <- Authenticate("twitter", appName = myKeys$appName, apiKey = myKeys$apiKey, 
                            apiSecret = myKeys$apiSecret, accessToken = myKeys$accessToken,
                            accessTokenSecret = myKeys$accessTokenSecret)
                             
twitterData <- twitterAuth %>%
               Collect(searchTerm = "#auspol", searchType = "recent", numTweets = 100, 
                       includeRetweets = FALSE, retryOnRateLimit = TRUE, writeToFile = TRUE, 
                       verbose = TRUE)

actorNetwork <- twitterData %>% Create("actor", writeToFile = TRUE, verbose = TRUE)

actorGraph <- actorNetwork$graph # igraph network graph

# Optional step to add additional twitter user info to actor network graph as node attributes 
actorNetWithUserAttr <- AddTwitterUserData(twitterData, actorNetwork,
                                           lookupUsers = TRUE, 
                                           twitterAuth = twitterAuth, writeToFile = TRUE)

actorGraphWithUserAttr <- actorNetWithUserAttr$graph # igraph network graph

semanticNetwork <- twitterData %>% Create("semantic", writeToFile = TRUE)

Youtube Examples

library(magrittr)
library(vosonSML)

# Authenticate with youtube, Collect comment data from videos and then Create an actor network
myYoutubeAPIKey <- "xxxxxxxxxxxxxx"

myYoutubeVideoIds <- GetYoutubeVideoIDs(c("https://www.youtube.com/watch?v=xxxxxxxx",
                                          "https://youtu.be/xxxxxxxx"))
                                 
actorNetwork <- Authenticate("youtube", apiKey = myYoutubeAPIKey) %>%
                Collect(videoIDs = myYoutubeVideoIds) %>%
                Create("actor", writeToFile = TRUE)

Reddit Examples

library(magrittr)
library(vosonSML)

# Collect reddit comment threads and Create an actor network with comment text as edge attribute
myThreadUrls <- c("https://www.reddit.com/r/xxxxxx/comments/xxxxxx/x_xxxx_xxxxxxxxx/")

actorNetwork <- Authenticate("reddit") %>%
                Collect(threadUrls = myThreadUrls, waitTime = 5) %>%
                Create("actor", includeTextData = TRUE, writeToFile = TRUE)

Save and Load Authentication Objects

# Save the object after Authenticate 
saveRDS(my_twitter_auth, file = "~/.twitter_auth")

# Load a previously saved authentication object for use in Collect
my_twitter_auth <- readRDS("~/.twitter_auth")

For more detailed information and examples, please refer to the function Reference page.

Special thanks

This package would not be possible without key packages by other authors in the R community, particularly: igraph, rtweet, RedditExtractoR, data.table, tm, magrittr, httr and dplyr.
