stemming - Details

  Key Concepts: 
  Stemming is a feature of SAP Predictive Analytics that helps to reduce the size of a dataset by removing words with the same root. This is done by removing suffixes, prefixes, and other inflections from words. For example, the words “running”, “runs”, and “ran” all have the same root word “run” and can be reduced to one word. This helps to reduce the size of a dataset and make it easier to analyze. 
  
  How to use it: 
  Stemming can be used in SAP Predictive Analytics by selecting the “Stemming” option in the Data Preparation tab. This will allow you to select which words you want to stem and which ones you want to keep as is. Once you have selected the words you want to stem, click “Apply” and the stemming process will begin. 
  
  Tips & Tricks: 
  When using stemming, it is important to remember that some words may have multiple meanings depending on their context. For example, the word “run” can mean both “to move quickly” or “to operate a business”. In this case, it is important to make sure that you are selecting the correct words for stemming so that your analysis is accurate.
