What is the primary purpose of stemming and lemmatization in natural language processing?Question 5Answera.To translate text from one language to anotherb.To identify and classify named entities in textc.To reduce words to their base or root forms to normalize text d.To remove stop words from the text
Solution
The primary purpose of stemming and lemmatization in natural language processing is c. To reduce words to their base or root forms to normalize text.
Here's a step-by-step explanation:
-
Stemming and lemmatization are both techniques used in natural language processing (NLP) to prepare text for further processing or analysis.
-
Stemming is a process where words are reduced to their word stem, base or root form. For example, the stem of the words "jumping" and "jumps" is "jump".
-
Lemmatization is similar to stemming but it brings context to the words. So it links words with similar meaning to one word. For example, "good", "better", or "best" is mapped to "good".
-
The main purpose of both stemming and lemmatization is to reduce inflectional forms and sometimes derivationally related forms of a word to a common base form, thereby normalizing text.
-
By doing this, it helps in reducing the complexity of the text data and consolidating similar words to a single term, which can be very useful in many NLP tasks like text classification, sentiment analysis, etc.
-
It's important to note that stemming and lemmatization do not translate text from one language to another, identify and classify named entities in text, or remove stop words from the text. These are different tasks in NLP.
