What is Query Lemmatization?

Query Word Lemmatization ✂️📖 is a linguistic process that reduces words to their base or dictionary form, also known as the lemma.

Unlike stemming (which simply chops off word endings), lemmatization considers the context and meaning of a word in its specific usage.

Example:

• ✅ “Better” and “Good” are related.
• ✅ “Better” is the comparative form of “Good”.
• 🔍 In a search query, lemmatization would allow a search for “good” to also return results for “better” because the system understands they share the same root meaning.

🔍 Why is Lemmatization Important?

• 🧠 Natural Language Understanding
• 📑 Information Retrieval
• 📝 Text Understanding
• 🔍 Text Clustering

Example:

Let’s say you’re searching for the term “running” 🏃‍♀️ in a document.

If the document contains the words “runs” or “ran”, a simple search might miss these words because they’re not exactly “running”.

✅ How Lemmatization Works:

• “Runs”
• “Ran”
• “Running”

All come from the same root word – “Run” 🏃. So, it treats them as the same word, making your search more effective ✅.

🚀 Applications in NLP

• 📑 Information Retrieval
• 🧠 Text Understanding
• 🔍 Text Clustering

By understanding word relationships, lemmatization improves search accuracy 🎯✨!
