In a typical data science workflow, the initial steps are to identify relevant data sources and request data from various departments and source systems. The bulk of time is then spent cleaning and transforming the data before models can be built.

In this tutorial video, you will learn more about how to analyze structured sales data combined with unstructured financial and news data to look for potential repeat customers in a sales performance database enriched with outside datasets. We’ll cover important additional topics along the way, such as how to handle personally identifiable information (PII).

In most environments, data scientists have to wait for experts to provide the requested data. Depending on the effort involved and on competing priorities, this process can sometimes take weeks or months before data is available for analysis. The business impact of these delays include crippled analytics projects, missed windows of opportunity, and unmet deadlines.

In the ideal scenario, the data scientist has tools to engineer features and can build models without dependencies. IBM offers self-service data preparation services for data scientists that are agile and interactive.

IBM Watson Studio and IBM Watson Knowledge Catalog include Data Refinery for self-service data preparation. Data Refinery puts data pre-processing and feature engineering in the hands of data scientists, enabling faster data insights. Data visualization aids in tedious and iterative data cleansing and shaping tasks.

Watson Knowledge Catalog enables data scientists to access curated data sets that are known and trusted by the organization. Immediate access to ‘source of truth’ data can simplify or eliminate a number of process steps.

Data Refinery key capabilities include:

  • Intuitive data transformation — Shape and clean data using graphical interfaces or a library of templates populated with powerful data transformation operations using code.
  • Rapid feedback on the data shaping process — Data visualization and profiles help to guide data preparation steps, reveal data quality issues, and avoid missteps.
  • Increased confidence in data quality — Incremental snapshots enable data scientists to gauge success over time. Visualization and data-shaping tools make it easy to iteratively remediate data quality issues.
  • Support large data sets — Steps can be saved in projects, edited, and run against larger data sets.

In the following video, I’ll demonstrate the visual capabilities of IBM’s data shaping tools using an end-to-end example:

  • Refine depersonalized, sensitive data in Watson Knowledge Catalog
  • Clean and refine data using quick, built-in operations or code
  • Leverage incremental snapshots, data profiles, and visualizations to guide the preparation of data for analysis

Stay tuned for Part 2 of this blog where I’ll show examples of combining financial data with sales data through the power of collaboration.

Part 3 of this blog will provide a deeper dive into preparing and analyzing a mixture of structured and unstructured data sources.
