    Year 1 Year 2 Year 3
    Social network sources:
    • YouTube
    • Flickr
    • Twitter
    • blogs
    Research tool development and baseline data
    Baseline information:
    • data extraction
    • content creation statistics
    • patterns in terms and themes
    • baseline social networking map
    • interconnections between social network spaces
    Content creation patterns
    Changes over time:
    • short-term statistics
    • regular / seasonal patterns
    Cluster profiling:
    • common themes / patterns
    • lead users
    Focus on specific events
    Cultural dynamics:
    • rapid spread of new ideas
    • communication across clusters
    • thematic discourse analysis
    • relationship with main- stream media coverage
    Research tools:
    • network crawler
    • content scraper
    • content analysis
    • network analysis
  • Methodology – Twapperkeeper
  • Data Processing – Twitter
    Typical data structure (#ausvotes):
  • Data Processing – Twitter
    Tools:
    Gawk – Scripting tool für CSV processing (open source)
    Excel – Data aggregation, pivot tables and charts
    Leximancer / WordStat – Keyword extraction, co-occurence matrices
    Gephi – Network analysis and visualisation (open source)
    # Extract @replies for network visualisation
    #
    # this script takes a CSV archive of tweets, and reworks it into network data for visualisation
    #
    # expected data format:
    # text,to_user_id,from_user,id,from_user_id,iso_language_code,source,profile_image_url,geo_type, # geo_coordinates_0,geo_coordinates_1,created_at,time
    #
    # output format:
    # from,to,tweet,time,timestamp
    #
    # the script extracts @replies from tweets, and creates duplicates where multiple @replies are
    # present in the same tweet - e.g. the tweet "@one @two hello" from user @user results in
    # @user,@one,"@one @two hello" and @user,@two,"@one @two hello"

    BEGIN {
    print "from,to,tweet,time,timestamp"
    }
    /@([A-Za-z0-9_]+)/ {
    a=0
    do {
    match(substr($1, a),/@([A-Za-z0-9_]+)?/,atArray)
    a=a+atArray[1, "start"]+atArray[1, "length"]
    if (atArray[1] != 0) print $3 "," atArray[1] "," $1 "," $12 "," $13
    } while(atArray[1, "start"] != 0)
    }
    # filter.awk - Filter list of tweets
    #
    # this script takes a CSV or other list of tweets, and removes any lines that don't include RT @username
    # the script preserves the first line, expecting that it contains header information
    #
    # script expects command-line argument search={searchcriteria} _before_ the input CSV filename
    # enclose the search term in quotation marks if it contains any special characters
    #
    # e.g.: gawk -F , -f filter.awk search="(julia|gillard)" tweets.csv >filteredtweets.csv
    #
    # expected data format:
    # CSV or simple list of tweets, line-by-line
    #
    # output format:
    # same as above, listing only retweets
    #

  • Prelude: Leadership #spill
    23 June, 19:00-00:00:Speculation
    24 June, 08:00-15:00:Party Vote & Aftermath
  • #spill Discussion Network (Node size: indegree [most @replies received]; node colour: outdegree [most @replies sent])
  • #ausvotes: Overall Activity (17 July – 24 Aug. 2010)
  • #ausvotes: Discussion Network(17 July to 25 Aug. 2010 / All @replies / Node size: Indegree / Node colours: betweenness centrality)
  • #ausvotes: Mentions of the Parties (normalised per day)
  • #ausvotes: Mentions of the Leaders (normalised per day)
  • #ausvotes: Mentions of the Leaders (cumulative)
  • #ausvotes: Key Themes
  • #ausvotes: Key Themes (normalised per day)
  • #ausvotes: Distractions (normalised per day)
    Labor’sTwibbon Campaign  RTs
  • #ausvotes: Distractions
  • Notes and Limitations
    Twapperkeeper relies on #hashtags
    Problem if #hashtags are inconsistent/unclear
    Follow-on @replies and retweets may not continue to use #hashtags
    Casual commenters may not use #hashtags in the first place
    May miss early developments – e.g. #hashtag standardisation
    Twitter as a subset of society:
    Broadband policy and Internet filter over-, asylum seekers underrepresented
    #hashtag use is a further sign of self-selection
    Need to look to Twitterfirehose for more comprehensive picture
    Need to track baseline activity to understand how exceptional #ausvotes was
