Decomposing Texts with Bag
of Words Model
2
Basic Concepts
Topic Overview: Introduction to the Bag of Words (BoW)
model, a foundational method in textual data
representation and language processing.
Functionality of BoW:
Unordered Collection: Treats each document as a collection of
words without considering their order.
Focus on Frequency: Concentrates on the frequency or occurrence
of each word, ignoring grammar and word order.
Feature Extraction: BoW extracts features based only on
word multiplicity, disregarding positional data and
grammatical rules.
Example Illustration: Sentences like “The cat sat on the
mat” and “The mat sat on the cat” have identical
representations due to ignoring word order.
Importance in NLP: Serves as a foundational basis for
various text processing and language-related tasks.
Limitations: Lack of sensitivity to syntax and semantics,
leading to potential loss of meaning and context.

Vector Representation
Core Concept: BoW model represents documents as frequency vectors.
Vector Definition in Mathematics: Traditionally, an object with magnitude and direction,
used to represent physical entities.
Vector Transformation in NLP: In the BoW model, v
