CCB302 – Digital Media Analytics - semester 2 2023 – A2 Project Brief 2
Introduction CCB302 students are being asked to perform an analysis of real-world data collected over a period of time. The topic is the 2023 Voice Referendum.
As part of this assignment, you are encouraged to review the upcoming Referendum
in which all eligible Australian voters must vote on 14-Oct 2023.1 Note: For over a decade, the Voice Referendum has been supported by governments led by both Australian Coalition and Labor governments. More recently, the issue has become politicised by the Opposition and several prominent Aboriginal politicians. Many Australians consider the Referendum a human rights issue. You may find that contemporaneous issues such as an investigation of Australia’s national airline, Qantas, has been woven into the Voice Referendum discussion. This may inform part of your analysis.
NOTE: This is not a hypothetical case. We are analysing real world data on the
upcoming Voice Referendum.
For this project, we are analysing real-word data that is deeply personal for many people, first
& foremost, Australia’s First Peoples. The datasets contain emotional, and sometimes
hyperbolic content. As digital communication students and soon communication
professionals, this reflects the type of analysis one does in the ‘real world’ and it can be
disturbing. If it raises any serious concerns, please contact QUT Student Counselling
immediately.2
Background and methods In this exercise, you are provided four data sets with video and comments data, similar to Assignment 1; however, instead of a single video (on AI and healthcare), students will have four files to facilitate temporal analysis (before & after Garma). We will discuss how to do this in tutorials, or you are encouraged to experiment on your own using what you learned about JOINING datasets earlier this semester (for A1).
1 Aboriginal and Torres Strait Island Voice. The Voice Referendum will be held on 14-Oct 2023, and
Australians will have a say about whether to change the Australian Constitution to recognise First
Peoples of Australia by establishing a body called the Aboriginal and Torres Strait Islander Voice. Source:

To help you get started, we have provided preliminary metrics on the YouTube data. As you begin your own analysis, you may ‘sanity check’ your initial findings in terms of number of unique videos, dates and channels posting content against our initial analysis. If there are discrepancies, seek to understand why and explain them. This is raw real-world data, so there will be inconsistencies and missing data (i.e., videos, comments, and users who are missing or have been deleted). That is usual and expected; you are welcome to identify that in your analysis. There are no intentional ‘red herrings’. We want you to explore the data with an open mind and surface insights. And remember, social media
content is ephemeral! The data were retrieved from YouTube Data API using the QUT Digital Observatory’s tool call ‘Youte’. You have previously received information about this tool and encouraged to review the lectures and URLs provided to refresh your memory on how it works. You are being asked to perform mixed methods analyses using YouTube metadata. Textual analysis is done using Leximancer. Quantitative and qualitative data can be plotted using Tableau. You are welcome to incorporate other tools you may be familiar with, however, you must use Leximancer and Tableau at a minimum. The matching criteria was as follows: • “voice referendum australia” • published before 19 June 2023 • This date is before the 2023 Garma Festival of Traditional Cultures, Australia’s largest Indigenous cultural gathering taking place in early August in northeast Arnhem Land.3 These datasets are called “before Garma”. • We have collected data after the Garma Festival, between 1 and 15 August 2023, called “after Garma.”
3 The Garma Festival of Traditional Cultures (Garma) is Australia's largest Indigenous cultural
gathering, taking place over four days each August in northeast Arnhem Land, in the Northern Territory,
Australia. Hosted by the Yothu Yindi Foundation, Garma is a celebration of the cultural traditions of
the Yolngu people, and a major community gathering for the clans and families of the Arnhem Land
region. The event showcases traditional miny'tji (art), ancient story-telling, manikay (song),
and bunggul (dance). It is held at Gulkula, a significant Gumatj ceremonial site about 40 kilometres
(25 mi) from the township of Nhulunbuy, attracts more than 2500 guests each year and is often sold out
months in advance.
In recent years, Garma has become an important fixture on the political calendar, attracting business,
political, academic, and philanthropic leaders to help shape Indigenous affairs policy through the Key
Forum conference. Source: https://en.wikipedia.org/wiki/Garma_Festival_of_Traditional_Cultures

Suggested prompts for your analysis (qualitative and quantitative) 1 Who are the channels publishing videos before & after Garma on this topic? Were they the same or different? 2 You can hone in on the top 5-10 publishers and interrogate information on the leading publishers. 3 Alternatively, you may wish to examine the ‘long tail’ of publishers of content and discuss that. 4 What is their geographic location? (Australia, overseas?) What can you deduce from the level of interest delivered by platforms in languages other than English? 5 How many followers do they have? 6 What categories do they publish? 7 Are they considered an authoritative source? 8 Consider the [political] alignment (conservative to progressive). 9 What is their geographic reach? (What is YouTube’s geographic reach?) 10 What is the timeframe of the post (original post & comments)? 11 How many people commented (total vs. distinct)? 12 What can be said about the nature of comments based on the metrics? 13 Is there any spamming, trolling, bot activity, or any indication of automated posting? 14 What other events were co-incident with this time period? 15 What is the sentiment of the videos published by the top 5 – 10 publishers. What can be said about the nature of comments? 16 What themes or topics surfaced before and after the Garma Festival (using textual analysis approach)? How do you know?
17 If you ‘tune’ Lexicmancer, be sure to keep careful track of what changes you made and
discuss them in the analysis. We will explore this in more detail during the remaining
tutorials. 18 What tool(s) was used to retrieve YouTube metadata? Who produced it? (hint: see https://youte.readthedocs.io/en/latest/). 19 What are the rate limitations of the YouTube API quote system? (hint: see https://youte.readthedocs.io/en/latest/#rate-limit-and-youtube-api-quota-system 20 What tool(s) did you use to analyse the YouTube metadata?
CCB302 – Digital Media Analytics - semester 2 2023 – A2 Project Brief 9
21 Are there other tools you could have used for gathering video data and statistics? If so, what is another tool you identified? 22 What are some of the limitations of analysing metadata from digital media platforms generally, or YouTube specifically? 23 What additional data would have made your analysis more robust and thorough? 24 What are some of the data governance considerations (hint: see https://youte.readthedocs.io/en/latest/#data-governance-considerations) 25 Are there any other things you can tell that we didn’t think of? The above are some of the prompts you may wish to investigate. There may be other insights you find and you are encouraged to discuss them!
