Study Notes
Course Information
- Course Title: Natural Language Processing (CS411P)
- Grade Level: 4th Year
- Instructor: Dr. Reem El-Deeb
- Semester: First Semester 2022-2023
- University: Mansoura University
What is NLP?
- NLP aims to enable computers to understand human language (spoken and written).
- This involves analyzing and synthesizing natural language.
NLP Applications
- Spell checking and keyword searches
- Extracting data from websites (e.g., prices, dates, location, names)
- Classifying different types of text
- Sentiment analysis
NLP Applications Examples
-
Machine Translation: Translating between languages. The example provided involved a threat email to Guam related to a potential bio-chemical attack.
-
Speech Recognition (ST): Converting sound to text.
-
Text-to-Speech (TTS): Converting text to sound. A visual of the graph to compare female and male speakers was included.
-
Question Answering: Utilizing systems like Watson to answer complex questions.
-
Spam Detection: Identifying spam email using machine learning algorithms.
-
Sentiment Analysis: Determining the emotional tone of text (e.g., positive, negative, neutral).
NLP Applications Cont
- Caption Generation: Creating descriptions for images. The example included three different image captions.
- Spoken Dialog Systems (Chatbots): Automated conversational systems.
- Complex Question Answering: Advanced question answering systems.
Why is NLP Hard?
- Vagueness and Imprecision: Language is often not precise.
- Redundancy: Multiple ways of expressing the same idea.
- Ambiguity: A single word or phrase might contain different meanings.
- Non-linguistic cues: Physical gestures, facial expressions influence meaning.
- Dynamic nature of language: Vocabulary and grammar change over time.
NLP Categories
- NLP involves both understanding and generation of natural language.
- This process involves different linguistics levels (i.e. phonology, morphology, syntax, semantics and pragmatics).
Categories of Linguistic Knowledge
- Phonology: The study of speech sounds
- Morphology: How words are formed from smaller units
- Syntax: The rules that govern how words are arranged in phrases and sentences.
- Semantics: How meaning is created in language
- Pragmatics: Understanding language in context
- Discourse: Coherent sequences of sentences.
