The vosonSML
R package is a suite of easy to use
functions for collecting and generating different types of networks from
social media data. The package supports the collection of data from
twitter
, youtube
and reddit
, as
well as hyperlinks
from web sites. Networks in the form of
node and edge lists can be generated from collected data, supplemented
with additional metadata, and used to create graphs for Social Network
Analysis.

The following usage examples will provide a quick start to using
vosonSML
functions. Additionally there is an Introduction
to vosonSML vignette that is a practical and explanatory guide to
collecting data and creating networks.
The process of authentication, data collection and creating networks
in vosonSML
is expressed with the three functions:
Authenticate, Collect and Create. The
following are some examples of their usage for supported social
media:
Twitter | YouTube | Reddit | Hyperlink | Supplemental Functions
verbose
: most vosonSML
functions accept a
verbosity parameter that is now set to FALSE
by default.
When FALSE
functions will run silently unless there is an
error. If set to TRUE
then progress and summary information
for the function will be printed to the console.The following environment options can also be used:
voson.msg
: If set to FALSE
then the
verbose output of functions will be printed using the base
cat()
function instead of the message()
function. Set by entering options(voson.msg = FALSE)
, and
clear by assigning a value of NULL
.voson.data
: If set to an existing directory path the
writeToFile
output files will be written to that directory
instead of the working directory. Can be set using
options(voson.data = "~/vsml-data")
for example, and
cleared by assigning a value of NULL
. Directory paths can
be relative to the working directory or full paths.Authentication objects generally only need to be created
once unless your credentials change. Save twitter
and
youtube
authentication objects to file after creation and
then load them in future sessions.
Please note in the examples provided that the “~” notation in paths are short-hand for the system to use the users home directory, and the “.” at the start of file names classifies it as a hidden file on some OS. You can name and save objects however you wish.
# youtube data api key
<- Authenticate("youtube", apiKey = "xxxxxxxxxx")
auth_yt
# save the object after Authenticate
saveRDS(auth_yt, file = "~/.auth_yt")
# load a previously saved authentication object for use in Collect
<- readRDS("~/.auth_yt") auth_yt
Please note that vosonSML
only accesses the Twitter
v1.1
API via rtweet and does not
support the newer v2
API at this time. Please refer to the
VOSON Lab voson.tcn
package if you are interested in using the v2
API to
collect and analyse Twitter conversation networks.
voson.tcn
has features to collect tweets and conversation
threads by url or id, and similarly to vosonSML
produces
activity
and actor
networks with additional
metadata.
The Twitter features of this version of vosonSML requires rtweet v1.0 or later.
packageVersion("rtweet")
## [1] '1.0.2'
Authenticate
is used to create an object that contains a
Twitter token for accessing the Twitter API. This can and should be
re-used by saving it once to file after calling
Authenticate
and then by loading it again during future
sessions.
library(vosonSML)
# twitter authentication creates an access token as part of the auth object
<- Authenticate("twitter", bearerToken = "xxxxxxxxxxxx")
auth_tw_bearer
# save the object to file after authenticate
saveRDS(auth_tw_bearer, file = "~/.auth_tw_bearer")
# load a previously saved auth object for use in collect
<- readRDS("~/.auth_tw_bearer") auth_tw_bearer
Collect
can be used to perform a twitter search with a
search term or collect tweets from timelines using user names. The
following example collects 100 recent
tweets for the
hashtag #auspol
and creates a dataframe with the collected
tweet data.
# set output data directory
options(voson.data = "./vsml-data")
# collect 100 recent tweets for the hashtag #auspol
<- auth_tw_bearer |>
collect_tw Collect(searchTerm = "#auspol",
searchType = "recent",
numTweets = 100,
includeRetweets = TRUE,
writeToFile = TRUE,
verbose = TRUE)
## Collecting tweets for search query...
## Search term: #auspol
## Requested 100 tweets of 45000 in this search rate limit.
## Rate limit reset: 2022-08-16 02:51:42

## Collected 100 tweets.
## RDS file written: ./vsml-data/2022-08-16_023645-TwitterData.rds
## Done.
The next example collects the 100 most recent tweets from the
@vosonlab
and @ANU_SOC
user timelines. Note
that this method requires the endpoint = "timeline"
parameter.
# collect 100 timeline tweets for each specified user
<- auth_tw_bearer |>
collect_tw_tl Collect(endpoint = "timeline",
users = c("vosonlab", "ANU_SOCY"),
numTweets = 100,
writeToFile = TRUE,
verbose = TRUE)
## Collecting timeline tweets for users...
## Requested 200 tweets of 150000 in this search rate limit.
## Rate limit reset: 2022-08-16 02:51:45
##

## Collected 200 tweets.
## RDS file written: ./vsml-data/2022-08-16_023648-TwitterData.rds
## Done.
The output for these methods also lists the earliest and most recent tweet as well as the number of tweets collected.
Because vosonSML
uses the rtweet
package to
access and collect tweets data, rtweet
data is also able to
be easily imported from dataframe or file and then transformed into a
Collect
object for further use.
<- rtweet::search_tweets("#auspol", n = 20)
tweets <- ImportRtweet(tweets)

The twitter Create
function accepts the data from
Collect
and a type parameter of activity
,
actor
, semantic
or twomode
that
specifies the type of network to create from the collected data.
Create
produces two dataframes, one for network
nodes
and one for node relations or edges
in
the network. These can then undergo further processing as per the supplemental functions section or be
passed to the Graph
function that creates an
igraph
object.
Nodes are tweets and edges are the relationship to other tweets such
as reply
, retweet
or quote
tweets.

YouTube uses an API key rather than an OAuth token and is simply set
by calling Authenticate
with the key as a parameter.
# youtube authentication sets the api key
<- Authenticate("youtube", apiKey = "xxxxxxxxxxxxxx") auth_yt
Once the key is set then Collect
can be used to collect
the comments from specified youtube videos. The following example
collects a maximum of 100 top-level comments and all replies from each
of the 2 specified video ID’s. It produces a dataframe with the combined
comment data.
<- c("https://www.youtube.com/watch?v=AQzZNIyjyWM",

The reddit API end-point used by vosonSML
does not
require authentication but an Authenticate
object is still
used to set up the collection and creation operations as part of a
reddit workflow. The reddit Collect
function can then be
used to collect comments from reddit threads specified by URL’s.
# specify reddit threads to collect by url
<- c(
thread_url "https://www.reddit.com/r/datascience/comments/wcd8x5/",

Collect
is limited to the first 500 comments per thread. It
is therefore suited to collecting only smaller threads in their
entirety.
Nodes are original thread posts and comments, edges are replies directed to the original post and to comments made by others.

The vosonSML
hyperlink collection functionality does not
require authentication as it is not using any web API’s, however an
Authenticate
object is still used to set up the collection
and creation operations as part of the vosonSML
workflow.
The hyperlink Collect

seed web pages, as well as corresponding type
and
max_depth
parameters for each page.
Please note that this implementalion of hyperlink collection and networks is still in an experimental stage.

The AddText
function can be used following the creation
of all networks for twitter
, youtube
and
reddit
. It will add an attribute starting with
vosonTxt_
to nodes of activity
networks and to
edges of actor
networks. It requires a collected
datasource
from which to extract text data.
An additional parameter hashtags
is available for
twitter
networks that will add tweet hashtags as an
attribute.

AddText
will also redirect some edges in a youtube
actor
network by finding user references at the beginning
of reply comments text using the repliesFromText
parameter.
In the following example an edge would be redirected from
UserC
to UserB
by text reference as opposed to
UserA
who made the top-level comment both users are
replying to.
# video comments
# UserA: Great tutorial.
# |- UserB: I agree, but it could have had more examples.
# |- UserC: @UserB I thought it probably had too many.

to

AddUserData
adds user profile information from the
users
dataframe to as many users in a twitter
actor
and 2mode
network as possible. If the
profile information is not available for referenced users in the collect
data then the user id and name will be added to the
missing_users
dataframe. If the profile metadata is not
available in the collect data and the lookupUsers
parameter
is set then additional twitter API requests will be made to retrieve the
missing information.

AddVideoData
adds video information as node attributes

with a user (channel owner or publisher). The actorSubOnly

Continue working with the network graphs using the
igraph
package and check out some examples of plots in the
Introduction
to vosonSML vignette. The graphml
files produced by
vosonSML
are also easily imported into software such as Gephi for further visualization and
exploration of networks.
As an alternative to vosonSML
using the R command-line
interface we have also developed an R Shiny app called VOSON Dash. It provides
a user friendly GUI for the collection of data using
vosonSML
and has additional network visualization and
analysis features.
For more detailed information about functions and their parameters, please refer to the Reference page.
This package would not be possible without key packages by other authors in the R community, particularly: data.table, dplyr, httr, igraph, RedditExtractoR, rtweet and tidytext.
