A Beginner’s Guide to Natural Language Processing (NLP)

Natural Language Processing (NLP), an innovative technology capable of understanding and decoding human language, has brought significant breakthroughs in many sectors, transforming how we communicate with machines. From social media monitoring to text classification, NLP plays a crucial role by effectively processing vast amounts of unstructured data. So, let’s dive into the world of NLP and discover the power of language in the digital age.

What is Natural Language Processing (NLP) ?

Natural Language Processing (NLP) is an exceptional technological development enabling computers to understand human communication nuances accurately. With NLP implementation, machines gain proficiency in understanding both written and spoken language, allowing them to provide comprehensive descriptions, summaries, and analyses that resemble human-style writing. Therefore, it has enabled efficient interaction between users and AI products available today in our daily lives. NLP is used in various domains and applications, such as information retrieval, machine translation, speech recognition, etc.

NLP’s rising demand highlights broader accessibility & availability of quality data paired with advancements in processing power are contributing factors for its booming adaptation rate contributing significantly towards improved user experience across various platforms.

Natural Language Processing techniques

The field of Natural Language Processing involves utilising either syntax-based or semantics-based techniques. Syntax-oriented strategies work by evaluating sentence structure and grammar rules to comprehend written or verbal communication, whereas semantic methods involve deciphering meaning through an understanding of contextual clues within a text or speech sample. To understand NLP techniques comprehensively, it’s essential to examine both approaches in further depth.

Syntax-based Techniques:

  • Tokenisation: This method breaks down text into smaller units called tokens. Like individual words or subword units. 
  • Part-of-Speech Tagging: It involves assigning grammatical tags to every word in a sentence, including nouns, verbs, adjectives, and adverbs. 
  • Parsing: it is the process of examining sentences’ grammatical structure, identifying word relationships, and generating parse trees that depict the syntactic framework.
  • Named Entity Recognition (NER): It identifies and sorts different kinds of named entities such as person names, locations, organisations or dates.

Semantics-based Techniques:

  • Word Sense Disambiguation: It aims to pinpoint the accurate meaning of ambiguous words by analysing the context, related semantics, and adjoining vocabulary. 
  • Semantic Role Labeling: This helps in recognising and distinguishing the role an entity plays within a sentence; these roles may include subject, object, and predicate, thereby revealing its overall semantic structure for better understanding.
  • Sentiment Analysis: It helps in determining the underlying tone within a text. It analyses the text for positive, negative, or neutral emotions so that it can be accurately classified across various levels.
  • Question Answering: It is a process that involves understanding and interpreting inquiries to provide accurate responses. It relies on extracting relevant information from a text corpus to deliver precise answers.

Uses of Natural Language Processing

NLP’s applications span a wide range of domains, from social media monitoring to text classification, where it excels in efficiently processing large volumes of unstructured data. Now, let’s delve deeper into some of the significant uses and applications of NLP:

  • Machine translation: NLP plays a crucial role in the operation of machine translation setups that allow seamless translation across different languages. These setups rely on NLP algorithms to decipher sentence meanings and accurately produce translations.
  • Text Summarization: The abundance of online data can be overwhelming for internet users seeking rapid access to crucial information. Fortunately, with advancements in Natural Language Processing (NLP), the creation of condensed versions known as “summaries” has become achievable. These summaries allow readers to save time by presenting a concise rendition that captures the essential points emphasised in a lengthier article or document.
  • Speech Recognition: Speech recognition systems are made possible due to NLP techniques, enabling computers to convert spoken words into written text. This groundbreaking technology finds applications in various areas, including voice assistants, transcription services, and other impressive speech-to-text functionalities.
  • Information Retrieval: The invaluable assistance of Natural Language Processing is the crucial element that enables search engines to accurately understand user queries and extract relevant information from vast amounts of text data.


In conclusion, Natural Language Processing (NLP) is a game-changing technology in our tech-focused era that deserves recognition and focus. The ability of computers to understand human speech through NLP has greatly improved user experiences on various platforms. By accurately capturing human expression nuances, NLP facilitates seamless communication between humans and machines, enhancing user experiences everywhere.

Down the road, the prospective advantages of NLP are quite massive, and without a doubt, NLP will become more intelligent and sophisticated as technology continues to progress rapidly.

The ultimate result? Machines that boast a greater ability than ever before when it comes to understanding human language. In practical terms, we will see more advanced chatbots and enhanced voice assistants. Beyond consumer applications, businesses are also positioned to benefit. Equipped with state-of-the-art analytical tools that leverage natural language processing, they will uncover valuable insights hidden within vast amounts of unstructured text data.
