FAQ about Natural Language Processing
NLP works walking on several steps. For example, first it cleans and tokenises text, then looks over its grammar and structure (parsing). As the next step, it works with techniques like word embedding to understand meaning. At the final phase, it applies machine learning to perform tasks varying from translation, text classification, or automatic speech recognition (ASR).
Some popular NLP applications are known to be sentiment analysis, which means detecting opinions, information extraction to pull out names, dates, etc., machine translation to translate languages, virtual assistants, chatbots, and natural language generation (NLG) in order to auto-generate text.
NLP encounter a variety of challenges, such as bias in NLP models, which means training data might reflect unfair stereotypes and some privacy concerns in NLP. This comes into play especially when processing sensitive data, and the most visible challenge is the high computational cost of large models.
Popular NLP tools are the Natural Language Toolkit (NLTK), which facilitates everything from parsing to tokenisation and named entity recognition (NER). Other libraries based on transformer models also shine for special tasks like text classification and semantic parsing.
Rule-based NLP depend on grammar, handcrafted rules, and linguistic knowledge, while Statistical NLP counts on data when learning patterns. The rule-based systems are known to be interpretable, while statistical NLP, especially coupled with deep learning, scales better and adapts to new data quickly.
