Text and sentiment analysis
It’s a great day in sports analytics! Sentiment analysis is a relatively new technique which is now being used in sports analytics. Today, we will discuss what text and sentiment analysis entails and how it is applied in sports.
What is sentiment analysis?
When we talk about Sentiment Analysis (also called Mining of Opinions or Emotional Artificial Intelligence), we are referring to a series of applications of natural language processing techniques, computational linguistics and text mining, which aim to extract subjective information from generated content by users such as comments on blogs, social media, etc.
With this type of technology, we can extract a tangible and direct value, such as “positive”/”negative”, from a textual comment.
Depth of analysis
To speak of Mining of Opinions is to speak of an increasingly extensive field related to the analysis of the subjective components that are implicit in the contents generated by the users. Within this field, there are applications that perform a more or less profound analysis of the textual content, depending on the task or problem that you want to solve. In general, we find two types of tasks related to Mining Opinions:
- Polarity detection: This refers to being able to determine if an opinion is positive or negative. Beyond a basic polarity, you can also obtain a numerical value within a certain range, which in a certain way tries to obtain an objective rating associated with a certain opinion.
- Analysis of sentiment based on characteristics: This refers to determining the different characteristics of the product, personality or team treated in the opinion or review written by the user, and for each of those characteristics mentioned in the opinion, be able to extract a polarity. This type of approach is much more complex and much finer than the detection of polarity.
Relaying it to sports
Relating sentiment or emotional AI to sports, for example, we live in the era of the “experts” of football, of deep analysis and of special guests who are ex-technicians and ex-football players who manage and weave countless possibilities. This generation of wise men analyze corner shots, make sketches on blackboards and between questions and answers assemble alignments and predict results. It is the intellectual age of football that has caused a notable influence on managers, coaches and footballers. Nobody escapes excessive criticism.
From the show to the commercialization
For those who have the opportunity to see soccer players and national teams, such as Brazil and Germany, get an exciting match every tie.
In the past, journalistic specials were unavoidable without the topic of “Pelé” being touched upon.
After the Argentina World Cup 78, soccer as a show and as a business began to take commercial roots. From the quality and brilliance of the Brasileirao, we passed to the skill and “malice” of the Argentineans without stopping recognizing the birth of new stars such as Diego Armando Maradona that led to the second albiceleste title in Mexico 86. There began sentiments.
The soccer world relives the golden stage of a rivalry created at the beginning of sports analysis, between Argentines and Brazilians. To be more concrete, between Pelé and Maradona. Who’s the best? This first controversy flooded the South American soccer world of an absurd rivalry that was well-taken advantage of by the merchants of the best spectacle of the world. From there, fierce rivalry and sentiments took over the football world.
