Natural Language Processing (Nlp)

Natural Language Processing (NLP) enhances interactions between computers and human language, crucial for data scientists to extract insights from unstructured data.

Understanding Natural Language Processing

Natural Language Processing (NLP) focuses on enabling machines to understand and generate human language, essential for data scientists dealing with unstructured data.

Types Of Nlp Tasks

In this section, we explore various Natural Language Processing (NLP) tasks including text preprocessing, classification, named entity recognition, machine translation, and speech recognition.

Text Preprocessing

Text preprocessing is an essential step in Natural Language Processing that prepares raw text data for analysis by converting it into a structured format.

Text Classification

Text classification is a crucial Natural Language Processing (NLP) task that involves categorizing text into predefined classes.

Named Entity Recognition (Ner)

Named Entity Recognition (NER) is a key NLP task that involves identifying and classifying proper names and other entities in text.

Machine Translation

Machine Translation is the process by which computer programs automatically translate text from one language to another.

Speech Recognition And Text-To-Speech

This section discusses the fundamentals of speech recognition and text-to-speech technologies, detailing their functionalities and applications.

Nlp Pipeline

The NLP Pipeline outlines the essential steps involved in processing natural language data, including data collection, preprocessing, feature extraction, model training, and evaluation.

Feature Extraction Techniques

Feature extraction techniques transform text data into usable numerical formats for machine learning.

Bag Of Words (Bow)

The Bag of Words (BoW) model is a simple and effective technique used in Natural Language Processing for text representation based on word frequency.

Term Frequency – Inverse Document Frequency (Tf-Idf)

TF-IDF is a numerical statistic that reflects the importance of a word in a document relative to a collection of documents, emphasizing words that are more unique to individual documents.

Word Embeddings

Word embeddings are vector representations of words used in NLP to capture the semantic meanings and relationships between words.
