A branch of artificial intelligence that deals with the interaction between computers and humans through natural languages. The goal of Natural Language Processing (NLP) is to enable computers to understand and process human language so that they can perform various tasks in this field.
Main Branches
1 . Syntactic Analysis
Involves determining the grammatical structure of sentences and identifying the components of sentences (such as nouns, verbs, adjectives, etc.) and the relationships between them.
2 . Semantic Analysis
Focuses on understanding the meanings of sentences and words. It deals with identifying multiple meanings, semantic relationships, and extracting semantic information.
3 . Named Entity Recognition (NER)
Involves identifying and classifying names, locations, dates, and organizations in text. This helps extract specific information from the text.
4 . Sentiment Analysis
Analyzes the emotions and sentiments present in the text and can help determine whether a text is positive, negative, or neutral.
5 . Natural Language Generation (NLG)
This subfield involves generating natural and comprehensible texts. For example, converting numerical data into descriptive sentences.
6 . Text Summarization
The goal of this field is to automatically produce a summary of long texts. This can include extractive summarization (selecting important sentences from the text) or abstractive summarization (creating a new summary text).
7 . Machine Translation
Involves the automatic translation of texts from one language to another. Systems like Google Translate are examples of this subfield.
8 . Speech Analysis
Involves processing and analyzing audio signals and converting them to text. This includes speech recognition and voice identification.
9 . Language Modeling
This field focuses on predicting the next words in a sentence based on previous words and is crucial for improving performance in other Natural Language Processing (NLP) applications.
10 . Chatbots and Human-Computer Interaction
Designing and implementing systems that can engage in natural and meaningful conversations with humans.
