Mastodon network Create() function named subtype for creating variations to the activity and actor networks. For the activity network a subtype = tag parameter can be used to create a tag network of post tags that are colocated. For the actor network a subtype = server parameter can be used to create a server network, which is an actor network reduced to server associations.Mastodon authentication, collection and network creation. There are two options for Mastodon collection, a hashtag search for global or local server timeline posts that is optionally authenticated: Collect.search.mastodon(), and a public thread collection function using input URL’s that is similar to Reddit thread collection that requires no authentication: Collect.thread.mastodon(). To access these methods via Collect an endpoint = "search" or endpoint = "thread" parameter should be passed to the functions.Mastodon authentication and collection uses the rtoot package and a function has been created for importing rtoot data into vosonSML called ImportRtoot. Imported data can be passed as input to the Create network functions.Reddit URL parsing in which thread ID’s were limited to 6 characters.2mode networks to use option specified method.Twitter networks caused by missing columns in the data.tidytext and tokenizers packages due to a change in the ICU library unicode standard and the stringi package (tokenizers issue #82). This affects only the generation of semantic and 2mode twitter networks and the fix maintains their functionality until an alternative tweet tokenization method is implemented. Unfortunately these two twitter network types are not supported on systems using ICU library versions >= 72.0 at this time.Twitter caused by unexpected type when data merging.rtweet v1.1.Twitter timeline collection.Reddit thread collection where URL’s missing trailing slashes would trigger loop protection errors.sort parameter value for Reddit threaad collection to be NA. Default sort order on Reddit is not a fixed value.sort parameter to Reddit collection. As this collection method is limited, it may be useful to request comments in sort order using the Reddit sort options top, new, controversial, old, qa and best.Collect.listing function for subreddits on Reddit. This is not a search, however it allows complete metadata for a specified number of subreddit threads to be collected in sorted order. The sort options are hot, top, new and rising. There is a further time parameter period that can be set to hour, day, week, month, year or all if sort = top, meaning for example, results sorted by top threads over the last week.Collect and Merge functions when writeToFile = TRUE. The log file is written in the same location as the data file with the .txt extension appended.option(voson.data = "my-data") to now attempt to create the directory if it does not exist.Collect.reddit().Collect.web() (#49).vosonSML Twitter functions to support major changes made in rtweet release version 1.0.2.endpoint parameter to the Twitter Collect function. It is set to search by default, which is the usual collect behaviour, but can also now be set to timeline to collect user timelines instead. See Collect.timeline.twitter() for parameters.vosonSML functions are now silent by default. Using the verbose parameter will again print function output.message() function instead of the cat() function by default. Setting the global option option(voson.msg = FALSE) will again redirect output to cat(). The option can be removed by assigning a value of NULL.voson.data option allowing a directory path to be set for writeToFile output files. Files are output to the current working directory by default, however a new directory can now be set with option(voson.data = "my-data") for example. The directory path can be relative or a full path, but must be created beforehand or already exist. If the path is invalid or does not exist it will continue with the default behaviour. This option can be removed by assigning a value of NULL. This will not effect other file write operations performed by the user.Twitter AddText() and AddUserData() functions now work with most Twitter network types.AddText() now adds columns for embedded tweet text and has a hashtags parameter to add a list of tweet hashtags as a network attribute.AddUserData() now adds an additional dataframe for missing_users. It lists the ids and screen names of users that did not have metadata embedded in the collected data. Using the lookupUsers parameter will retrieve the metadata using the twitter API. Additonally passing the refresh = TRUE parameter will now retrieve and update the metadata for all users in the network.tweets and users.ImportData function and replaced it with ImportRtweet() for rtweet version 1.0 format data.Merge() and MergeFiles() functions to support the merging of collected data from separate operations. These functions support input of multiple Collect objects or .RDS files, automatically detect the datasource type and support the writeToFile parameter for file output of merged data.YouTube id extraction from url function to be more robust and added support for YouTube shorts urls.GetYoutubeVideoIDs function. The YouTube collect function parameter videoIDs will now accept video ids or video urls.auth_twitter_app(), auth_twitter_dev() and auth_twitter_user() functions for each token type. The collect_reddit_threads() and collect_web_hyperlinks() functions skip the unecessary Authenticate step for Reddit and web data collection.status ID to summarise collected tweet range. The Min ID and Max ID are not necessarily the earliest and latest tweet in the tweets collected and therefore not ideal for delimiting subsequent collections. Instead the two Earliest Obs and two Latest Obs tweets as returned by the Twitter API are now reported.enpoint parameter to Collect, allowing search or timeline to be specified for a twitter data collection. If it is not specified the default is a twitter search.timeline collection accepts a users vector of user names or ID’s or a mixture of both, and will return up to 3,200 of each users most recent tweets.Create.actor.twitter and Create.activity.twitter to use dplyr and data.table techniques consistent with other package network creation functions. Both functions are significantly faster for large collection dataframes.Create.actor.twitter includes two new parameters for mentions, inclMentions that will process and include mentions edges in the network and inclRtMentions that will process and include mentions found in retweets. The inclMentions parameter is set to TRUE by default and inclRtMentions set to FALSE. The inclRtMentions parameter is a subset of mentions, therefore for it to be set to TRUE, inclMentions must also be TRUE.Create.activity.twitter network creation. Added author_id and author_screen_name to nodes to assist with labels or re-creating tweet URLs from data.rmEdgeTypes parameter to Create.activity.twitter and Create.actor.twitter. These accept a list of edge types that can be filtered out of the network during network creation.Graph function.Min ID will be the same, but sometimes the Min ID is outside of the expected collection range. The last observation is a more reliable tweet to use as the starting point for subsequent search collections.Collect method with hyperlink network creation. The Create function with activity type parameter creates a network where nodes are web pages and edges the hyperlinks linking them (extracted from a href HTML tags). The actor network has page or site domains as the nodes and again the hyperlinks from linking pages between domains.vctrs error when using dplyr functions. The classes are no longer needed post-method routing so they are simply removed.dplyr::funs function that was generating a warning.Create.semantic.twitter and Create.twomode.twitter functions using the tidytext package. They now better support tokenization of tweet text and allows a range of stopword lists and sources to be used from the stopwords package. The semantic network function requires the tidytext and tidyr packages to be installed before use.Create.semantic.twitter:
removeNumbers and removeUrls, default value is TRUE.assoc parameter has been added to choose which node associations or ties to include in the network. The default value is "limited" and includes only ties between most frequently occurring hashtags and terms in tweets. A value of full will also include ties between most frequently occurring hashtags and hashtags, and terms with terms creating a more densely connected network.stopwords language e.g stopwordsLang = "en" and source e.g stopwordsSrc = "smart" have been added. These correspond to the language and source parameters of the tidytext::get_stopwords function. The stopwords default value is TRUE.Create.twomode.twitter function is weighted by default but can be disabled by setting the new weighted parameter to FALSE.replies_from_text parameter to repliesFromText and at_replies_only to atRepliesOnly in the AddText.actor.youtube function for consistency.tm package dependency.Introduction to vosonSML vignette Merging Collected Data examples.Collect.youtube that was causing no video comments to be collected if there were no reply comments for any of the videos first maxComments number of top level comments. For example, if maxComments is set to 100 and the first 100 comments made to a video had no replies then no results would be returned.rtweet::rate_limit function that resulted in an error when using the rtweet retryonratelimit search parameter. The rate_limit function was being called by vosonSML to check the twitter rate limit regardless of whether the search parameter was set or not, and so was failing Collect with an error. A fix was made so that vosonSML checks if rtweet::rate_limit succeeds, and if not automatically sets retryonratelimit to FALSE so that a twitter Collect can still be performed without error should this problem occur again.jsonlite::fromJSON.tictoc package from dependency imports to suggested packages.rtweet package is installed.RedditExtractoR package from imports.twomode networks.reddit gsub locale error https://github.com/vosonlab/vosonSML/issues/21.bimodal network hashtags to lowercase as filter terms when entered are converted to lowercase.bimodal and semantic networks.GetVideoData() function call in AddVideoData.AddText functions related to strict typing by dplyr::if_else function.AddText function to redirect edges towards actors based on the presence of a screen name or @screen name that may be found at the beginning of a reply comment. Typically reply comments are directed towards a top-level comment, this instead captures when reply comments are directed to other commenters in the thread.actor network identifiers to be their unique Channel ID instead of their screen names.AddVideoData function to add collected video data to the youtube actor network. The main purpose of this function is to replace video identifiers with the Channel ID of the video publisher (actor) instead. To get the Channel ID of video publishers an additional API lookup for the videos in the network is required. Additional columns such as video Title, Description and Published time are also added to the network $edges dataframe as well as returned in their own dataframe called $videos.AddText function to add collected text data to networks. This feature applies to activity and actor networks and will typically add a node attribute to activity networks and an edge attribute to actor networks. For example, this function will add the column vosonTxt_tweets containing tweet text to $nodes if passed an activity network, and to $edges if passed an actor network.igraph graph objects and subsequent writing to file has been removed from the Create function and placed in a new function Graph. This change abstracts the graph creation and makes it optional, but also allows supplemental network steps such as AddText to be performed prior to creating the final igraph object.writeToFile parameter from Create functions and added it to Graph.weightEdges, textData and cleanText parameters from Create.actor.reddit. cleanText is now a parameter of AddText.activity.reddit and AddText.actor.reddit.AddTwitterUserData with AddUserData function that works similarly to AddText. This function currently only applies to twitter actor networks and will add, or download add if missing, user profile information to actors as node attributes.rtweet::create_token. Method is used when only twitter app name and consumer keys are passed to Authenticate.twitter as parameters. e.g Authenticate("twitter", appName = "An App", apiKey = "xxxxxxxxxxxx", apiSecret = "xxxxxxxxxxxx"). A browser tab will open asking the user to authorize the app to their twitter account to complete authentication. This is using twitters Application-user authentication: OAuth 1a (access token for user context) method.file) via the HTTPUserAgent option. It is temporarily set to package name and current version number for Collect e.g vosonSML v.0.27.2 (R Package).Create.semantic.twitter in which a sum operation calculating edge weights would set NA values for all edges due to NA values present in the hashtag fields. This occurs when there are tweets with no hashtags in the twitter collection and is now checked.Create.semantic.twitter were also fixed.Collect.twitter in which any additional twitter API parameters e.g lang or until were not being passed properly to rtweet::search_tweets. This resulted in the additional parameters being ignored.SaveCredential and LoadCredential functions, as well as the useCachedToken parameter for Authenticate.twitter. These were simply calling the saveRDS and readRDS functions and not performing any additional processing. Using saveRDS and readRDS directly to save and load an Authenticate credential object to file is simpler.cleanText parameter works in Create.actor.reddit so that it is more permissive. Addresses encoding issues with apostrophes and pound symbols and removes unicode characters not permitted by the XML 1.0 standard as used in graphml files. This is best effort and does not resolve all reddit text encoding issues.Collect.twitter summary information that includes the earliest (min) and latest (max) tweet status_id collected with timestamp. The status_id values can be used to frame subsequent collections as since_id or max_id parameter values. If the until date parameter was used the timestamp can also be used as a quick confirmation.Collect method.Create.actor.twitter and Create.bimodal.twitter in which the vertices dataframe provided to the graph_from_data_frame function as a contained duplicate names raising an error.twitteR twitter collection implementation with the rtweet package.twitter authentication token can now be cached in the .twitter_oauth_token file and used for subsequent twitter API requests without re-authentication. A new authentication token can be cached by deleting this file and using the re-using the parameter useCachedToken = TRUE.
