Now that data is more important than ever and organizations are finally able to turn their massively collected data into value, the quality of data becomes crucial. Because, where we used to say, “Garbage in, garbage out”, the accessibility through AI changes the saying into “Garbage in, garbage everywhere ...”
On the positive side, once organizations internalize a high-performing culture around data, they can turn the risk of working with data into an asset that differentiates them from other organizations. To cultivate a high-performing culture around data, organizations should start by embedding data-driven decision-making at every level. This involves providing employees with the right tools and training to handle data effectively, fostering an environment of continual learning and improvement. Leaders should prioritize data quality and accountability, setting clear expectations and encouraging collaboration across departments. By leveraging AI for data management, organizations can ensure data integrity and empower employees to focus on strategic initiatives rather than manual processes.
Let’s dive a bit deeper into tangible steps for data quality with which you can leverage AI to help you. To get to a higher level of data quality and efficient monitoring, we differentiate three crucial steps that follow a recurring time cycle:
- Data profiling
The first step in enhancing data quality involves diving into the world of data profiling, in which we analyze and evaluate our datasets. With traditional methods, we relied on reactive calculations to assess data, such as completeness, consistency, and uniqueness of columns, but now imagine a world where we leverage AI to swiftly detect patterns both within and across datasets, paving the way for proactive improvements. It's like embracing a data-driven approach to data quality enhancement – and believe it or not, AI excels at this.
To give an example, an algorithm can easily learn that a date has to follow a standardized pattern (DD-MM-YYYY). But I imagine that you are unimpressed: “Any data steward could have come up with this as well.” True, but AI can also learn that it is logical for a shipment date to be at a later point in time than an order date. Or maybe that there is a pattern between three, four or even more columns within your data that data stewards would have taken a lot longer to come up with. AI does this by scoring patterns within your dataset, the higher the score, the more likely the pattern is. Let AI be the hyperintelligent sidekick of your data stewards, enabling them to do their work much faster and much more consistently across the organization. Identifying these types of patterns is crucial for good data quality, as it lets you steer on the data quality you derive from these patterns by generating data quality rules.
- Implementing data quality rules
Now that we have an optimized set of data quality rules for our data, let’s leverage AI for the implementation as well. Organizations typically implement data quality rules per data product or data domain. But as our data products and domains multiply, AI can come to our aid, identifying similarities between them and suggesting unified data quality rules. This means no more endless handovers to data quality boards! Instead, data stewards can easily accept suggested (and internally approved) rules for data objects like ‘Client identifier’, streamlining this entire process.
By implementing these data quality rules, an estimate can be given on whether the data at hand is of a sufficient quality to be used as training data for other models. Create an upward spiral of leveraging AI to get good data quality into your AI solutions. Besides the traditional data quality rules mentioned, there should be rules to ensure objectivity and reduce bias as much as possible.
- Data quality remediation
And that's not all – we cannot overlook the role of AI in data quality remediation. Once you are monitoring your data quality through (AI-optimized) data quality rules, issues will inevitably start to become apparent in your data that you should act on. This requires attention in the form of remediation. There are multiple data remediation strategies and AI can help you automate those strategies.
Based on the data quality rules given to your data asset, the AI tooling will start to detect anomalies in the data and give you suggestions on how to resolve them. This consists of, among others, outlier removal, removal of duplicates, format standardization or imputing values of missing data. It is important to ensure that people with an understanding of the business assess the proposed data quality remediation efforts and either accept or reject them. But let’s also be realistic, not every data quality issue is to be resolved. Especially when we consider historical data issues, it is not always possible to solve the issue. However, AI can learn from the reasoning behind not solving an issue and include that suggestion in its future solution direction. This, as with all AI solutions, also lets the model learn from the feedback it has been given and increases its accuracy over time.
The symbiotic relationship between data quality and AI is undeniable: High-quality data fuels effective AI, while advanced AI techniques and technologies are pivotal in driving and maintaining superior data .
