What is Big Data?


According to Margaret Rouse, from Search, Data, and Management, Big Data is a combination of structured, semistructured and unstructured data collected by organizations, big tech companies, such as Google, Facebook, and Amazon. The gathering of Big Data can help organizations create machine learning projects and predictive modelings of consumer behavior. 

Concerns about Big Data


Although this article was meant to be just about "what is big data?". I would like to focus it on the concerns Joseph E. Stiglitz discusses in his book "People, Power, and Profits, Progressive Capitalism in an Age of Discontent", where, in a very short summary, he talks about the American economy and how the financial system is affecting society led by politicians who care more about money and follow their own personal interests instead of the society's.

In this book, the author writes a chapter aimed at emerging technologies, big data and AI and how they will affect the economy. 

One of his concerns is that as these big tech companies, mentioned in the first paragraph, already represent a monopoly and a dominant position in the tech industry and as they gathered more information about us, the users, they can exert more power over us. For example, the manipulation of the information we see, creating doubts over certain ideas and different opinions among people, as the Cambridge Analytica case in the 2016 EE.UU elections. 

Even though this information means that they can create tailor-made products based on the information analyzed, it will lead to higher market power under their hands, with huge consequences, creating even bigger financial and social inequality among citizens. 

Besides, monopolies are not incentivized to innovate, what they look to, is increased in profits and power. 

The author proposed some solutions among the user's privacy, as making personal information of our own property, but as we see in Europe with GDPR, there's a lot of flaws and this subject requires more attention and adjustments.

Benefits and Challenges of using Customer Data for Marketing

-
Customer data is defined as the information your customers provide while interacting with your business via your website, mobile applications, surveys, social media, marketing campaigns, and other online and offline avenues. (Deshpande, 2019).  Years ago, marketers would just target mass audiences with advertisements all around the city or on the TV. Of course, this represents big expenditures on marketing and very poor KPI metrics to monitor the effectiveness of the marketing campaigns.  Nowadays, marketers have access to a big amount of customer data but, why is customer data important for marketing? One of the benefits of customer data is that, and thanks to a single customer view database, we can know better target our customers. Segmenting customers is not only good for ensuring that the correct person receives the most appropriate message, but it is also far more cost-effective than a "one message fits all" approach to direct marketing. (Botibol, 2018). Hence, our...

AI for Marketing

-
Artificial Intelligence (AI) is the simulation of human intelligence processes by machines, especially computer systems. (Rousse, 2019).  Nowadays, AI is used in many fields, such as healthcare, education, finance, law, and manufacturing, but we are going to focus on how Marketing is using AI.  AI in marketing is the use of customer data, machine learning, and other computational concepts to predict a person's action or inaction. (Grimms, 2019).  It is important for digital marketers because artificial intelligence will allow analyzing big amounts of data from different platforms, such as social media platforms, emails and web activity in a very short period of time, thus, enhancing campaign performance and overall return on investment (ROI).  According to Dave Chaffey, AI is broken down into 3 different types of technology; machine learning; which uses algorithms to learn from historical data sets that can create propensity models, applied propensity models;...
