Process of Natural Language Processing (NLP)
Semantic and syntactic analysis are the two major procedures that are utilized to accomplish NLP-related tasks.
1. Syntactic Analysis
Syntax refers to forming a sentence with a group of words in a meaningful way. In NLP, this procedure is used to measure how natural language supports the rules of grammar.
Some computer algorithms are utilized to apply grammar rules to a collection of words and find out the actual meaning from them.
Here are some of the syntax methods that can be used:
- Lemmatization: It reduces the complexity of a word for making it easily understandable
- Morphological segmentation: It divides words into distinct parts
- Word segmentation: It devises a big text into separate units to improve its readability.
- Parts-of-speech: it identifies the part of speech for every single word
- Parsing: It checks the grammar of a sentence
- Sentence Break: It limits the length of each sentence to a big text.
- Stemming: It removes the modified words from their original form.
2. Semantic Analysis
Semantics means the actual meaning of the given text. Semantic analysis is the difficult procedure of Natural Language Processing (NLP), which is not fully resolved to date.
In this process, some computer algorithms are applied to analyze and understand the meaning of words, and to know the arrangement of sentences.
The key methods of semantic analysis include:
- Named Entity Recognition (NER): It categorizes the parts of a text into fixed groups. It means, NER identifies the same group of elements like people’s names, and place names, etc.
- Word Sense Disambiguation: It provides exact meaning to a word based on the situation.
- Natural Language Generation: It converts semantic meanings and translates them into human-understandable language.
Now, we’ll have a brief discussion on the growth of NLP technology by 2024.
Increased smartphone usage and adoption of cloud systems are two major factors behind the growth of the NLP and AI app development. Companies are using AI+NLP mobile apps and integrated systems to ensure better customer experiences.
According to the market reports, the market size of NLP technology is expected to increase from USD 10.2 billion in 2019 to USD 26.4 billion by 2024.
NLP-based sentiment analysis apps are more popular in the market. These apps can analyze sentiments of diverse datasets. This process can identify positive, negative, and neutral sentiments from the given text. Sentiment analysis applications are expected to grow at the highest rate during the forecasted period of 2019-2024.
Generally, the sentiment analysis is used for getting valuable insights from social media reviews, the company’s product reviews for making data-driven decisions. Hence, using NLP technology-based applications, organizations understand their customer requirements which result in improved brand recognition in the market.
3. Machine Translation
Machine translation (MT) refers to completely automatic software that can translate content from one language to some other languages. The perfect example of MT is ‘Google Translate’.
Machine translation is also known as instant translation or automated translation. It will even translate the essential data and speech into any other language without any human involvement.
The machine translations are divided into four types
- Rule-based Machine Translation (RMT)
- Statistical Machine Translation (SMT)
- Neural Machine Translation (NMT)
- Hybrid Machine Translation (HMT)
4. Speech Recognition
The major role of natural language processing in AI falls in recognizing human speech. Speech recognition technology has been around the world for the past 50 years.
Today, speech recognition is a trending topic that is a part of various products, including voice assistants (Siri, Google Assistant, Cortana, etc.). This speech recognition app replaces other time-taking methods like typing, selecting, or clicking the text in any other format.

6. Automatic Summarization
Automatic summarization is a method of creating a short, precise, and articulate summary of a longer text document. It comprises of diminishing a text and creating a compact new form that contains its most applicable information. It will be especially helpful to condense large bits of unstructured data, for example, academic papers.
There are two distinct methods for utilizing NLP for Summarization: the foremost extricates the significant data within a text and uses it to outline (extraction-based summarization);. At the same time, the second applies profound learning strategies to paraphrase the content and produce sentences that are not available in the primary source.
7. Spell Checking
Spell Checker is the most commonly used software tool by employees in every organization, especially the Text Editors or Content Developers. This awe tool recognizes any spelling errors in a sentence and rectifies them with correct spelling.
One of the most realistic examples of the spell-checking tools is the ‘Grammarly’ Application. Grammarly is an online (Free/Paid) grammar checker that examines your content for a wide range of errors, from grammatical errors to sentence structure mistakes and past.
8. Question replying (QA)
Question-Answering is turning out to be increasingly more popular thanks to the apps like Siri, chat boxes, virtual assistants, and OK Google. A QA application is a framework prepared to answers the questions raised by humans. It might be utilized as a text-only interface or as a verbally expressed system. While they offer an incredible guarantee, they have a long way to go still. It remains a significant test, particularly for web search engines, and is one of the principles uses of NLP.
Future Possibilities of NLP
Natural language processing in AI as technology continues to grow. NLP and AI apps will be more user-oriented and promise more personalized experiences.
An AI virtual assistant like Siri is the best natural language processing in AI example.
