lemmatization
What It Means
Lemmatization is a text processing technique that reduces different forms of the same word to their base dictionary form. For example, it converts 'running,' 'ran,' and 'runs' all back to 'run' so computer systems can recognize them as the same concept. This helps AI systems understand that these variations represent the same underlying meaning.
Why Chief AI Officers Care
Without proper lemmatization, your AI systems will treat word variations as completely different terms, leading to poor search results, inaccurate sentiment analysis, and missed patterns in customer feedback. This directly impacts the quality of business intelligence, chatbot performance, and automated content analysis that drives key decisions. Poor text preprocessing can make expensive AI investments deliver subpar results.
Real-World Example
A retail company analyzing customer reviews might see complaints about 'shipping' separately from complaints about 'shipped' and 'ships' without lemmatization. With proper lemmatization, all these variations get grouped under 'ship,' allowing the AI to correctly identify shipping as the top customer concern rather than splitting it across multiple seemingly unrelated categories.
Common Confusion
People often confuse lemmatization with stemming, but stemming simply chops off word endings while lemmatization actually understands grammar and context to find the proper dictionary form. Stemming might incorrectly reduce 'better' to 'bett' while lemmatization correctly identifies 'good' as the root.
