?What is tokenization in natural language processing (NLP)

Tokenization is the process of breaking down a text into smaller units called tokens, which are usually words or subwords. This step is essential in NLP as it forms the basis for subsequent analysis and processing tasks. Tokenization can be performed at different levels, such as word-level tokenization, which breaks text into individual words, or character-level tokenization, which breaks text into individual characters. Additionally, tokenization can handle more complex linguistic structures such as subword tokenization, which splits words into smaller units to handle morphologically rich languages or out-of-vocabulary words.

?What are some common tasks in natural language processing (NLP)

Natural language processing encompasses a wide range of tasks aimed at understanding and processing human language. Some common NLP tasks include: Text classification: Assigning predefined categories or labels to text documents based on their content. Named entity recognition (NER): Identifying and categorizing named entities such as names of people, organizations, locations, etc., mentioned in text. Sentiment analysis: Determining the sentiment or opinion expressed in text, such as positive, negative, or neutral. Machine translation: Translating text from one language to another automatically. Part-of-speech tagging: Assigning grammatical categories (such as noun, verb, adjective) to words in a sentence. Syntactic parsing: Analyzing the grammatical structure of sentences to identify relationships between words. These tasks are fundamental in NLP and serve as building blocks for more complex language understanding and generation applications.
