Here's a tabular representation of different NLP use cases and the technologies used (ML, DL, etc.) for each:

Use Case Technology Used Description
Text Classification ML (Logistic Regression, SVM), DL (CNN, LSTM) Categorizing text into predefined labels (e.g., spam detection, sentiment analysis).
Text Summarization DL (Transformers, LSTMs, GRUs) Generating concise versions of long text while preserving key information.
Machine Translation DL (Seq2Seq models, Transformers) Automatically translating text from one language to another.
Named Entity Recognition (NER) ML (CRF, SVM), DL (Bi-LSTM, Transformers) Identifying proper names, locations, organizations, etc., in text.
Part-of-Speech (POS) Tagging ML (HMM, CRF), DL (Bi-LSTM, Transformers) Assigning grammatical tags (e.g., noun, verb) to words in a sentence.
Clustering (Topic Modeling) ML (LDA, K-Means), DL (Autoencoders) Grouping similar documents based on themes without predefined categories.
Dependency Parsing ML (Graph-based models), DL (Bi-LSTM, Transformers) Analyzing grammatical structure by establishing relationships between words.
Constituency Parsing ML (PCFG), DL (Transformers) Breaking sentences into nested sub-phrases based on syntax rules.
Regular Expression Matching Rule-Based, ML (HMM) Finding patterns in text, such as extracting phone numbers or email addresses.
Finding Similar Words (Word Embeddings) DL (Word2Vec, GloVe, FastText) Mapping words to high-dimensional vectors based on contextual meaning.
Large Language Models (LLMs) & Prompt Engineering DL (GPT, BERT, LLaMA) Fine-tuning and using pre-trained models for various NLP tasks.
Building Foundational Models DL (Transformers, Self-Supervised Learning) Training massive models on large datasets for broad NLP capabilities.
