7 Key Steps In The Data Mining Process

process of data mining

Data Science:

Data science is a discipline that combines domain knowledge, computer skills, and math and statistics knowledge to extract useful insights from data.

To be competitive during the digital revolution, businesses needed to acquire and handle massive amounts of data. While most business owners understood the value of big data, they weren’t always sure how to use it to address business issues.

Business intelligence and analytics have now become a science. Engineers, data analysts, and other experts work with companies to sort through and aggregate data in order to extract insights. Here in this blog, we will discuss about process of data mining and to learn more about Data Science domain, join Data Science Course in Chennai.

Brief History of Data Mining:

  • Data mining started became popular in the 1970s and peaked about 2002.
  • Predictive analytics first surfaced in the 2000s, but it has yet to gain widespread acceptance. Businesses and government entities are the primary users.
  • According to experts in 2010, data science serves five functions. The scientist’s job is to collect data, clean it up, investigate it, model it, and analyse it.
  • The leading venues for data mining and analytics are now social media networks.

The Data Mining Process in 7 Steps

Businesses have access to a multitude of new data in today’s digital environment. Knowing which data sources to collect to connect with corporate objectives might be difficult. Businesses employ data mining and artificial intelligence to improve data collection and extract useful information.

  1. Data Cleaning

To ensure that all process data satisfies industry standards, teams must first clean it. Dirty or insufficient data causes poor insights and system failures, which costs time and money. All unclean data will be removed from the organization’s acquired data by engineers. Depending on the business’s resources, they apply a variety of data pretreatment and cleaning processes.

  1. Data Integration

Data integration is the term used when data miners join disparate data sets and sources to do analysis. This is one of the most effective mining strategies for streamlining the extraction, transformation, and loading processes.

During this step, many specialists clear up additional data in various databases. This eliminates any inconsistencies in the data and ensures data quality to fulfil business needs. To combine data, specialists will employ data mining technologies like Microsoft SQL.

  1. Data Reduction for Data Quality

This process retrieves relevant data for pattern analysis and evaluation. Engineers take a little amount of data and reduce it while maintaining its integrity. Teams may use neural networks or other types of machine learning during the mining process. Dimensionality reduction, numerosity reduction, and data compression are examples of strategies.

  1. Data Transformation

Engineers employ this industry standard process to convert data into a format that is suitable for mining. They combine the preparatory data in order to speed up data mining and make it easier to spot patterns in the final data set.

Data mapping and other data science approaches are included in data transformation. Smoothing or removing noise from data is one strategy. Aggregation, standardisation, and discretization are some more prominent strategies.

  1. Data Mining

To develop business information, companies utilise data mining applications to extract important trends and optimise knowledge discovery. This is only achievable if a corporation fully utilises big data and obtains the appropriate kind of data.

  1. Pattern Evaluation

This is the point at when engineers stop working behind the scenes and start sharing their findings with the rest of the world. Specialists will identify any useful patterns that can provide business information.

  1. Representing Knowledge in Data Mining

Finally, data analysts share information with others using a combination of data visualisation, reports, and other mining tools. Before the data mining process began, business leaders communicated data comprehension goals and objectives to technologists so that they know what to look for.
