What is Data Mining? Examples of data mining

In today’s highly digitized world, millions of pieces of information are processed daily. The amount of accumulated data continues to grow, and the shift towards a digital society has made information the most valuable asset for organizations. Modern companies have a wealth of data on their employees, customers, products, and services, with each piece of information is interconnected with other records. All this information is stored in intricate databases, the complexity of which increases with each passing day.  

According to statistics provided by IDC (International Data Corporation), in 2025 the Internet will consist of data occupying a total of 175 zettabytes.  

With such a vast amount of information being processed by users, governmental and non-governmental organizations, as well as the private sector, quick access to critical information and extraction of related data essential for delivering a complete service or product to a given customer becomes challenging. This is where a new, interdisciplinary field comes to the rescue.  

What is Data Mining? 

What is data mining? How do you analyze data? What does data mining prediction look like? These are some of the most common questions in the context of data mining, often encountered among the community of those interested in data analysis.  

Data Mining is one of the latest trends in the development of information technology. It is an interdisciplinary specialty that deals with data mining by means of available data analysis schemes. It is a technique that is increasingly being used by modern organizations to analyze data and represent it appropriately to facilitate the search for relationships between this data, to transform raw data in the organization’s resources (on-premise and cloud databases) into useful information and knowledge to build new services and products that meet the needs of the organization’s market and customers.  

The entire process of data mining is carried out by specialists – a data mining analyst is an individual educated in the field of computer analytics. Using various statistical, mathematical, and algorithmic techniques, the analyst examines data within an organization’s resources to extract information that is not immediately apparent and hasn’t been analyzed by automated systems for sorting and organizing data.  

Data mining serves two primary objectives:  

  1. Precise characterization and classification of the stored data.  
  1. Creating predictions for the future through the utilization of the available information.  

Irrespective of its application within an organization, data mining fundamentally revolves around uncovering concealed information that yields valuable insights, thereby enabling improved business decisions and strategies.  

Data mining is not only a business tool but also an immensely relevant and rapidly advancing research field. It continually evolves in tandem with technological progress, the growing volume of data, and its increasing accessibility. Data mining incorporates, among other things, machine learning languages and the latest algorithms based on artificial intelligence.  

During the data mining process, a data mining analyst needs to demonstrate not only technical skills and knowledge of the latest IT technologies, but also an understanding of the business and the context in which the data is being utilized. This holistic perspective ensures the effective extraction of insights that align with business goals.  

Data mining process 

The process of data exploration in data mining involves multiple steps aimed at discovering hidden patterns, rules, and relationships within the set of analyzed data.  

The basic process of data mining can be divided into several stages:  

  1. Defining the goal – clear definition of the analysis objective. It involves determining what information is to be provided after the data exploration process, achieved through data cleaning, integration, and transformation. An example of a defined goal could be identifying key factors affecting the successful launch of a new product or service onto the market.  
  2. Understanding the data – at this stage, a comprehensive examination of the dataset that will undergo exploration is carried out. The data’s structure, size, quantity, attributes, and potential gaps are thoroughly investigated.  
  3. Data preparation – this process involves data cleaning, transformation, and integration to make it ready for analysis. Duplicate data is removed, and missing information is filled in at this stage.  
  4. Choosing a data mining method – after preparing the dataset for analysis, the selection of a data mining method becomes possible. There are many different techniques and algorithms available, such as regression, classification, clustering, association analysis, and neural networks. The choice of the appropriate method depends on the specificity of the problem and the expected result.  
  5. Application of the chosen data mining method – at this stage, the data undergoes exploration using the selected data mining method.  
  6. Evaluation and interpretation of results – after conducting the data exploration process, the obtained results are analyzed and interpreted. This stage involves acquiring new knowledge or information that can lead to making better and more accurate decisions, or serve as material for further research and exploration.  
  7. Implementation of results and monitoring their effectiveness – the final stage involves putting the outcomes obtained from the data exploration process into practice and monitoring their effectiveness. Based on the patterns and information discovered, business actions are taken or further research is carried out. It’s also worth monitoring the results to track changes in data and potential updates to models or methods.  

It’s important to note that the data exploration process in data mining is iterative and dynamic. This means it may require the dynamic adjustment of research methods at various stages of exploration.  

What are the data mining methods? 

Some of the most popular data mining methods include:  

  1. Classification in data mining – used for predicting the membership of objects into specific classes or categories.  
  2. Regression – allows the prediction of numerical values of data based on other attributes.  
  3. Clustering – a technique for grouping similar data objects into clusters based on their similarity. It helps discover natural structures and patterns within data that haven’t been defined previously.  
  4. Association analysis – used to discover relationships and rules between sets of data elements. It is applied, for example, to identify purchasing rules in sales data. Customers buying a new smartphone often opt for a compatible case and screen protector.  
  5. Time series analysis – focuses on uncovering patterns, trends, and sequences of data based on a time unit. It’s valuable in analyzing time-dependent data sets and is utilized in fintech, meteorology, and medicine.  
  6. Neural networks – the most recent data mining technique that leverages the potential of neural networks, neural processors, and artificial intelligence. Neural networks are utilized for image analysis, speech recognition, and other tasks based on machine learning.  

Currently, data mining very often uses more than one research method. Combining several research methods allows to increase the efficiency and effectiveness of the data mining process. Data mining techniques are constantly evolving enabling new ways of data mining.  

What are the data mining tools used for?  

Tools utilizing data mining methods can be applied across a wide spectrum of uses. Some of the most popular examples of data mining tool applications include:
