Natural Language Processing (NLP) entails a computer program’s capability to comprehend human language, both spoken and written, commonly known as natural language.
This facet is an integral part of artificial intelligence (AI). NLP has a rich history spanning over 50 years, with its origins deeply rooted in the field of linguistics.
Its practical utility extends across diverse fields, such as medical research, search engines, and business intelligence.

How does natural language processing function?
NLP empowers computers to comprehend natural language in a manner akin to humans. Whether expressed verbally or in written form, artificial intelligence within natural language processing interprets real-world input, processes it, and comprehends it in a way that a computer can grasp.
Analogous to humans relying on various sensors like ears for hearing and eyes for seeing, computers utilize programs to read and microphones to capture audio.
Similar to the human brain processing input, computers employ programs to handle their respective inputs.
During processing, the input undergoes conversion into code that the computer can interpret. The natural language processing process comprises two primary phases: data preprocessing and algorithm development.
Data preprocessing involves refining and “cleaning” text data to make it analyzable by machines.
This step transforms data into a manageable format, emphasizing text features that an algorithm can utilize. Various methods achieve this, including:
Tokenization: Breaking down text into smaller units for analysis.
Stop word removal: Eliminating common words to retain unique, informative words.
Lemmatization and stemming: Reducing words to their root forms for processing.
Part-of-speech tagging: Marking words based on their grammatical roles, such as nouns, verbs, and adjectives.
Once data undergoes preprocessing, an algorithm is crafted for its processing. While numerous natural language processing algorithms exist, two primary types are commonly employed:
Rules-based system: This system relies on meticulously crafted linguistic rules and was prominent in early natural language processing development.
Machine learning-based system: Machine learning algorithms use statistical methods, learning tasks based on provided training data and adjusting methods with increased data processing. Employing machine learning, deep learning, and neural networks, natural language processing algorithms refine their rules through iterative processing and learning.
Unveiling the Significance of Natural Language Processing – Addressing Business Challenges with Unstructured Data
In the contemporary business landscape, organizations grapple with copious amounts of unstructured, text-heavy data, necessitating an efficient processing mechanism.
The wealth of information generated online and stored in databases often comprises natural human language.
Until recently, businesses faced challenges in effectively analyzing this data, highlighting the pivotal role of natural language processing.
Harnessing Precision: Navigating Data with NLP
The transformative power of natural language processing becomes evident when examining specific scenarios.
For instance, consider the statements: “Cloud computing insurance should be part of every service-level agreement,” and, “A good SLA ensures an easier night’s sleep—even in the cloud.”
Utilizing natural language processing for search purposes allows the program to discern cloud computing as an entity, recognize ‘cloud’ as an abbreviation for cloud computing, and understand SLA as an industry acronym denoting service-level agreement.
