Natural Language Processing (NLP) – 7 Impacts Of Natural Language Processing (NLP) Since Evolution
Natural Language Processing (NLP) is a subfield of computer science and artificial intelligence focusing on the interaction between humans and computers using natural language. It uses algorithms and statistical models to analyze and understand human language and generate natural language output.
NLP aims to enable computers to read, interpret, and understand human language in the same way humans do. This involves various tasks, including text classification, sentiment analysis, language translation, speech recognition, and more. NLP has many applications, including chatbots, voice assistants, search engines, and text analysis tools.
NLP involves a combination of techniques from computer science, linguistics, and machine learning. The field has seen rapid advancements in recent years, driven by large datasets’ availability and deep learning algorithms’ advances.

How does NLP work?
NLP involves several steps to process natural language input and generate natural language output. The basic steps involved in most NLP systems are:
- Text Preprocessing: This involves cleaning and normalizing the input text to remove irrelevant information, such as HTML tags or punctuation marks, and transform it into a structured format that can be analyzed.
- Tokenization: This involves breaking down the input text into individual tokens (words, punctuation marks, etc.) to facilitate further analysis.
- Part-of-speech (POS) tagging: This involves identifying the part of speech (noun, verb, adjective, etc.) of each token in a sentence.
- Named Entity Recognition (NER): This involves identifying and extracting named entities (such as people, places, and organizations) from a text.
- Dependency Parsing: This involves analyzing the grammatical relationships between words in a sentence, such as subject-verb-object relationships.
- Sentiment Analysis: This involves determining a piece of text’s emotional tone or sentiment.
- Natural Language Generation: This involves generating natural language output based on the input text, such as generating a summary or responding to a query.
These steps can be performed using various NLP tools and approaches, such as machine learning algorithms, statistical models, or rule-based systems. NLP systems can be trained on large datasets of annotated text to improve their accuracy and performance.
Overall, NLP involves linguistic and computational techniques to process natural language input and generate natural language output, enabling machines to understand and interact with human language.
NLP Tasks
NLP tasks can be broadly classified into three categories:
- Natural Language Understanding (NLU): This involves tasks related to understanding and analyzing natural language input, such as:
- Text Classification: Classifying text into predefined categories or topics.
- Sentiment Analysis: Analyzing the emotional tone or sentiment expressed in a text.
- Named Entity Recognition (NER): Identifying and extracting named entities like people, places, organizations, and other entities from text.
- Relationship Extraction: Identifying the relationships between entities mentioned in the text.
- Parsing: Analyzing the syntactic structure of a sentence or text.
- Natural Language Generation (NLG): This involves tasks related to generating natural language output, such as:
- Machine Translation: Translating text from one language to another.
- Text Summarization: Generating a summary of a piece of text.
- Text Generation: Generating natural language text from structured data or other input.
- Natural Language Interaction (NLI): This involves tasks related to enabling humans to interact with computers using natural language, such as:
- Question Answering: Answering questions posed in natural language.
- Chatbots: Generating responses to user queries or statements in natural language.
- Speech Recognition: Converting spoken language into text.
These tasks are not mutually exclusive, and many NLP systems may involve a combination of them.
NLP Tools And Approaches
There are a variety of NLP tools and approaches that are commonly used in natural language processing:
- Tokenization: involves breaking down the text into individual tokens (words, punctuation marks, etc.) to facilitate further analysis.
- Part-of-speech (POS) tagging: This involves identifying the part of speech (noun, verb, adjective, etc.) of each token in a sentence.
- Named Entity Recognition (NER): This involves identifying and extracting named entities (such as people, places, and organizations) from a text.
- Dependency Parsing: This involves analyzing the grammatical relationships between words in a sentence, such as subject-verb-object relationships.
- Sentiment Analysis: This involves determining a piece of text’s emotional tone or sentiment.
- Machine Translation involves translating text from one language to another using statistical models or neural machine translation.
- Chatbots: This involves using natural language processing to enable machines to converse with humans.
- Deep Learning: This involves training neural networks on large datasets to improve the accuracy of natural language processing tasks.
Many open-source libraries and frameworks are also available for implementing these tools and approaches, such as NLTK, Spacy, Gensim, and TensorFlow. These libraries provide pre-trained models and tools for common NLP tasks and can be used by developers to build NLP applications.
