However, the current panorama in not
that clear. This social media presence
requires communication departments to
account for the time and efforts devoted
to maintaining it and gathering the
highest possible interaction among the
community is key.
Also, organizations strive to uncover
which are the real key topics emerging
from their content strategies, and which
the publics use to form the mental image
of the brand.
Over the last few years, due to the
technological evolution in what concerns
web services, there has been an
enormous adherence to online Social
Networks.
One of the most used social networks in
the higher education sector is Facebook
and, currently, most top-ranked
Universities have an official page on it.
It would be expected the posts on that
page to follow an editorial guideline or
strategy, developed by the respective
communication/marketing department
and aligned with the institution’s strategic
purposes.
Motivation.
In our research we seek for automatic procedures to create a
digital footprint of an organization on social media.
In particular, to automatically uncover the publication strategy
such that it can be later on analyzed with other tools and insights.

Step 1a: understanding the
communication strategy.
• Posting frequency
• Period of the day of the posts
• Number of posts in each weekday
• Frequency of posting per month
• Topics of posting and the self-image
• Topical words in posts
• Sentiment words in posts
• Distribution of posts in topic areas
• Sentiment analysis
• Fading patterns

7. 7

8. 8
Step 1b: understanding the
response patterns.
• Frequency and intensity of comments
• Topics of comments
• Distribution of posts in topic areas
• Topics of posting and the self-image
• Sentiment analysis
• Aggregated sentiment in each HEI

9. 9

10. 10
Step 2: comparing HEI through
created metrics.
• Most active fans
• Feedback from Most Active Fan (MAF)
• Number of posts by a fan vs. number of users
• Type of post where comments are made
• Score of each HEI vs. the number of fans
• Fading patterns

Step 3: predictive analytics.
• In the prediction phase, we built three models to predict basically
three things:
• the engagement a post will have in the next 3 days;
• the average sentiment of the response it will have in the next 4 days;
• the fading of the response in the next 3 days.
• For the prediction we used “Random Forests”.
• To prevent overfitting, we divided the dataset into 80% for training
and 20% for testing (never previously used in the training).
• The results showed that the accuracy of the classifier was slightly
above 80%, and that the F1-measure was of 84%, both values were
computed as the average for each of the two metrics.

14. • We presented a three-step model to analyze the social media
communication of higher-education institutions. The base for our
study was the top 5 high-ranked university institutions of the World,
according to the QS World 2017 University Ranking.
• The final stage allows the prediction of which strategies will
potentially have more response and engagement; and, accordingly,
which will not.
• The evaluation of the model showed that the results are sufficiently
accurate to recommend the use of the system, although with some
care.
