How is NLP (Natural Language Processing) used daily?
Natural Language Processing (NLP) is the technology that enables computers to understand and process human language. It helps computers read text, interpret speech, analyze sentiment, and identify key information. NLP, machine learning, and deep learning are crucial aspects of Artificial Intelligence. NLP has a rich history dating back to the early 1900s and has evolved significantly. Alan Turing’s paper on a “thinking” machine in the 1950s inspired the development of NLP and the idea of AI. With the abundance of information available today, NLP plays a crucial role in translating data into actionable insights.
Importance of NLP in Real-Life:
- NLP automates the analysis of large volumes of unstructured text and speech data.
- NLP enables machines to interpret and manipulate hundreds of languages and dialects for various goals and agendas.
- NLP’s development over the years allows non-technical individuals to use computing systems and acquire data.
- NLP can be used for sentiment analysis to determine the emotions behind a text or speech.
- NLP plays a pivotal role in translating data sets into actionable information.
Components of NLP Used in Various Business Applications
NLP is divided into two components. NLP’s key components, Natural Language Understanding (NLU) and Natural Language Generation (NLG) are essential for diverse business applications in various industries:
Natural Language Understanding (NLU):
- NLU interprets the meaning of text or speech by analyzing its structure and content.
- It categorizes entities like names, dates, and locations in a text.
- NLU determines the sentiment expressed in text or speech.
- It helps in understanding customer feedback and preferences.
- NLU plays a crucial role in chatbots and virtual assistants.
Natural Language Generation (NLG):
- Organizes and structures content logically before generating human-readable text.
- Produces text using predefined templates or advanced techniques.
- Enables businesses to generate tailored content for specific needs.
- Condenses large volumes of information into concise summaries.
- Benefits industries deal with vast amounts of data, such as legal services, finance, and research.
Unlock the full potential of AI in various applications and develop cutting-edge solutions by harnessing the power of NLP components.
How does NLP work? - 7 Steps in NLP
Here are 7 steps that describe how NLP works:
Step 1: Tokenization
The first step in NLP is tokenization. Tokenization refers to breaking down a text into individual words or phrases, known as tokens. Tokenization involves removing punctuation and other unwanted characters and separating the text into meaningful units.
Step 2: Stop Word Removal
Stop words are common words that do not carry any significant meaning, such as “the,” “a,” and “an.” In the second step of NLP, stop words are removed from the text. Removing stop words helps reduce the text’s size and focuses on the important words in the text.
Step 3: Stemming and Lemmatization
The third step in NLP is text preprocessing, which includes stemming and lemmatization techniques. Stemming reduces words to their base form or stem, while lemmatization reduces them to their canonical form or lemma. Stemming normalizes words by predicting their parts of speech and returning them to their root form, while lemmatization removes inflectional endings to get the base form of a word. For example, the stem of the word “running” is “run.” Lemmatization, however, involves reducing words to their base form, known as a lemma. For example, the lemma of the word “running” is “run.”
Step 4: Part-of-speech (POS) Tagging
In the fourth step of NLP, a Part-of-Speech (POS) tag is assigned to each word to identify its grammatical role as a noun, verb, adjective, or adverb. POS tagging is crucial in understanding the text’s grammatical structure. NLP enables machines to comprehend human language for automated tasks like spell check, translation, social media monitoring, and more.
Step 5: Named Entity Recognition (NER)
Named Entity Recognition (NER) is the fifth step in NLP. NER involves identifying and categorizing named entities in the text, such as people, organizations, and locations. NER is important for information extraction, sentiment analysis, and chatbots.
Step 6: Sentiment Analysis
Sentiment analysis is the sixth step in NLP. Sentiment analysis involves analyzing the text to determine the overall sentiment, such as positive, negative, or neutral. Sentiment analysis is commonly used in social media monitoring, customer feedback analysis, and market research.
Step 7: Text Classification
Text classification is the final step in NLP. Text classification involves categorizing the text into predefined categories or classes, such as spam or not spam, positive or negative, or news or sports. Text classification is used in various applications, including email filtering, document categorization, and content recommendation.
