NLP interview questions

Below are few Frequently Asked NLP Interview Questions

• What is NLP?

NLP Stands for 'Natural Language Processing', that deals with the interaction between pc and human languages,
NLP could be a method for computers to investigate, understand, and derive from the human language during a good and helpful method. Using NLP, developers like machine-controlled outline, translation, named entity recognition, relationship extraction, sentiment analysis, speech recognition, and subject segmentation will organize and structure data to perform tasks.

• List some Components of NLP?
  Five main Component of Natural Language processing are:
  1.Pragmatic Analysis
  2.Discourse Integration
  3.Semantic Analysis
  4.Syntactic Analysis
  5.Morphological and Lexical Analysis

• List some areas of NLP?
  List some areas of NLP:-
  1.Text Classification and Categorization
  2.Named Entity Recognition (NER)
  3.Part-of-Speech Tagging
  4.Semantic Parsing and Question Answering
  5.Paraphrase Detection
  6.Language Generation and Multi-document Summarization
  7.Machine Translation
  8.Speech Recognition
  9.Character Recognition
  10.Spell Checking

• Define the NLP Terminology?
  NLP nomenclature Parsing or Dependency Parsing is that the task of recognizing a sentence and assignment a syntactical structure thereto. the foremost wide used syntactical structure is that the analyze tree which might be generated victimisation some parsing algorithms.

• What is Lemmatization in NLP?
  Lemmatization mostly used for refer to doing things properly with the vocabulary use and morphological analysis ofword,normally aiming to remove inflection ending only and the return base dictionary a word of from,

• What is stemming in NLP?
  Stemming is important in natural language understanding (NLU) and natural language processing (NLP). ... Stemming is also a part of queries and Internet search engines.Stemming is the process of reducing a word to its word stem that affixes to suffixes and prefixes or to the roots of words known as a lemma.

• What is dependency parsing?
  Dependency parsing is the task of dependency extracting a parse of a sentence which means sentence that represents, Its a structure of grammatical and defines between the relationships "head" words and words,those heads which modify.

• What is pragmatic analysis in NLP?8

Pragmatic analysis deals with outside word data, which implies data that's external to the documents and/or queries. linguistics analysis that focuses on what was delineated is reinterpreted by what it truly meant, derivation the assorted aspects of language that need world data.

• Explain Named entity recognition (NER)?
  NER Stands for Named entity recognition. It is a sub-task of information extraction that seeks out and categorizes specified entities in a body or bodies of texts. NER is also known simply as entity identification, entity chunking and entity extraction. NER is used in many fields in artificial intelligence including natural language processing and machine learning.

• What is NLTK?
  The Natural Language Toolkit (NLTK) is a platform used for building Python programs that work with human language data for applying in statistical natural language processing (NLP). It guides the reader through the fundamentals of writing Python programs, working with corpora, categorizing text, analyzing linguistic structure, and much more.

• What is the difference between NLP and NLU?
  NLP is brief for language process whereas NLU is that the shorthand for language understanding. equally named, the ideas each upset the connection between language (as in, what we tend to as humans speak, not what computers understand) and AI. information science will see a variety of tools, like speech recognition, language recognition, and language generation.

NLU Stands for language understanding, it's thought-about a subtopic of information science, language understanding could be a important a part of achieving roaring information science. NLU is narrower in purpose, focusing totally on machine reading comprehension: obtaining the pc to grasp what a body of text very means that.
Real-world samples of NLU vary from tiny tasks like supplying short commands supported comprehending text to some tiny degree, like rerouting associate degree email to the proper person supported a basic syntax and decently-sized lexicon.

• Explain the Masked Language Model?

Masked language modeling is an example of auto-encoding language modeling (the output is reconstructed from corrupted input) - we typically mask one or more of words in a sentence and have the model predict those masked words given the other words in sentence.By training the model with such an objective, it can essentially learn certain (but not all) statistical properties of word sequences.
