Practice - 5 Tasks

1fill in blank

easy

Complete the code to import the correct chunking class from LangChain.

LangChain

from langchain.text_splitter import [1]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Importing a character-based splitter instead of a semantic one.

Using a token splitter which is unrelated to semantic chunking.

The SemanticTextSplitter is used for semantic chunking strategies in LangChain.

2fill in blank

medium

Complete the code to create a semantic text splitter with a chunk size of 500.

LangChain

splitter = SemanticTextSplitter(chunk_size=[1])

Drag options to blanks, or click blank then click option'

A500

B1000

C200

D50

💡 Hint

Common Mistakes

Using a chunk size too large or too small for semantic chunking.

Confusing chunk size with chunk overlap.

Setting chunk_size=500 creates chunks of 500 characters or tokens for semantic splitting.

3fill in blank

hard

Fix the error in the code to split text semantically using the splitter.

LangChain

chunks = splitter.[1](text)

Drag options to blanks, or click blank then click option'

Asplit_text

Bchunk_text

Csplit

Dsemantic_split

💡 Hint

Common Mistakes

Using a method name that does not exist on the splitter object.

Confusing method names with other libraries.

The correct method to split text in LangChain's splitter is split_text.

4fill in blank

hard

Fill both blanks to create a semantic splitter with chunk size 400 and chunk overlap 50.

LangChain

splitter = SemanticTextSplitter(chunk_size=[1], chunk_overlap=[2])

Drag options to blanks, or click blank then click option'

A400

B50

C100

D10

💡 Hint

Common Mistakes

Swapping chunk size and overlap values.

Using overlap larger than chunk size.

Chunk size is set to 400 and chunk overlap to 50 for better semantic chunking.

5fill in blank

hard

Fill all three blanks to import, create, and split text semantically.

LangChain

from langchain.text_splitter import [1]

splitter = [2](chunk_size=300, chunk_overlap=20)

chunks = splitter.[3](document)

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using wrong method names for splitting.

Importing the wrong splitter class.

First import SemanticTextSplitter, then create an instance, and finally call split_text to split the document.
