Here comes the good part.
I am going to show you the 5 different data visualisations I have created, and I will introduce them with the question they answer to.
Which emojis did I use from 2014 to 2017 and in every single season?
This is my emoji-cloud representing the emojis sent in the selected period of time. The application is interactive, so I can select the year from the ‘Years’ axis and the season I want from the ‘Seasons’ axis.
The ‘Total’ option corresponds the sum of every other option in that bar.
I have used the 😍 emoji 20588 times (yep, I really like it, ahah).
How do I know this?
When the cursor is over an emoji, the program displays a label where the frequency of use of that emoji (in the selected period of time) is shown.
As you can see from the gif above, the dimension of the emojis could not have been proportional to each other, otherwise the emojis used only once could not have been visible. Since I wanted to show all the emojis, the dimension of the images is indicative.
But even if using this strategy, you are able to see that I do a massive use of certain emojis, while I occasionally use the rest of them.
I also wanted the different temporal views to be coherent between themselves. You can notice the drastic change of dimension of the images when I consider a shorter period of time.
What kind of emotions my emojis express? Is the sentiment of my emojis positive, neutral or negative?
In order to answer this question, I needed an emoji ranking kind of data. I was querying Google for ‘emoji psychology’, ‘emoji sentiment’ and so on, then I found a paper in which an emoji ranking is calculated. Here you can find the paper I’m talking about; here you can find the resulting ranking file.
The authors found a way to assign a positive, neutral and negative value to a limited set of emojis (751).
I decided to apply these results to mine, to discover how many emojis I used during 2015, 2016 and 2017 (the only years of which I had all the messages) and how many times I expressed positive, neutral and negative sentiments through those emojis.
If you look at the table you can see that every emoji has three values, so even if I use a happy emoji a little percentage of negative and neutral sentiment is still being counted. Looking at the values in the table I saw that there are certain emojis that have a predominant sentiment (or rather when
max (positive, neutral, negative) > sum (positive, neutral, negative) — max (positive, neutral, negative)) so I decide to also show (through the opacity channel) in my visualisation the number of times I was predominantly positive, neutral and negative.
I decided to represent the sentiments using this palette from Color Hunt, and in particular:
- positivity with the color #4E3188
- neutrality with #24BABC
- negativity with #EAEF9B
This is what the results look like:
What if I want to have a more detailed view of the single years?
If my cursor is over a year, I can see this:
The opacity of the bar states for how many times I was predominantly positive (neutral or negative) comparing to all the times I was positive (neutral or negative).
I don’t use emojis to express my neutrality: if I want to be neutral, I don’t use any emoji. And this is reflected on the opacity of the neutral sentiment in the three views above. I always use more positive emojis than negative ones, and in 2015 I used positive predominantly emojis (you can notice this by watching the opacity of the purple bar).
Which emojis do I send in which chat?
I wanted to explore the use of my 25 most used emojis of all time in the single chats, so I thought a correlation map could be useful for the sake of this.
I sorted my chats based on the amount of emojis I sent in them, and only took the ones in which I sent at least one emoji.
In the horizontal axis there are the sorted chats, in the vertical axis the 25 most used emojis. For filling the cells I used this palette. The more emojis I used, the more the color of the cell tends to be purple.
Starting from left, there is the chat with my boyfriend, the second is my bestfriend’s, then a group of girlfriends’, a group of college friends, a family group, another friend’s, my mom’s, and so on…
At the bottom of the visualisation there are cells which indicates the sum of the 25 most used emojis for every chat. You may have noticed that in one column the sum equals to 0, and that’s because in that chat I have used emojis, but these emojis do not belong to the set of the 25 most used. This also explains why, even if I sorted chats in decreasing order, the bottom sums are not ordered. It is because in some chats I used other kinds of emojis.
From this visualisation I have noticed that:
- I do a massive use of the 😍 emoji with my boyfriend;
- I’m often laughing in my messages;
- I express love using lots of different heart emojis. But there are some chats in which I never use this kind of emoji, even if I often write messages in them;
- I use emojis to express happiness, fun, love, sadness and sometimes surprise. As you can see there are not “neutral” emojis;
- the 😘 emoji was only sent to my closest contacts.
What about my mood in the chats?
The previous visualisation shows the use of emojis in every chat.
What if I want to see the mood of every chat?
Like in the previous visualisation, I sorted the chats based on the number of emojis I sent in them. Differently to that visualisation, though, here I considered all the 751 emojis in the paper (linked above), not only the 25 most used ones.
The first bar is my boyfriend’s. Yes, I use so many emojis with him.
At the top of each bar there is the number indicating the total number of emojis I sent. If you compare these numbers with the ones at the bottom of the previous visualisation, you can see that in most of the cases these numbers are greater than the other ones. This is because here, as I said above, I consider all the emojis, not only the most used ones. But in some cases the numbers in this vizualisation are lower than the others. Why? It is because even if here I want to consider all the emojis I’ve sent, I can only consider those emojis of which a probability of positivity, neutrality and negativity has been calculated in the paper. So even if here I consider more emojis (751 vs 25), because some of the emojis that I use the most were not considered in the experiment, the sum of the considered emojis sometimes is lower.
Anyway, in my opinion the visualisation is still representative and realistic.
How many emojis did I sent every single day from the beginning? My journey on Telegram
Now I would like to go deeper and see my entire experience on the Telegram platform. How many emojis did I sent every single day from the beginning? Were they positive, neutral or negative?
For each day of each month of every year of my journey on Telegram, I drawn three circles and filled them with the colours in this palette:
- positive sentiment: #FC85AE
- neutral sentiment: #9E579D
- negative sentiment: #574B90
I also used the opacity channel for understanding how many times my positive, neutral and negative emojis expressed a predominant sentiment.
