Part 1. What is Natural Language Processing

NLP, or Natural Language Processing, is an artificial intelligence (AI) technology that has been used for more than 50 years. This technology refers to the ability that a computer program can identify and understand the spoken and written language of humans well. It is rooted in the linguistic field and has been used in many other fields. When you use translation tools, chatbot tools, search engines, voice assistants, or do medical research, you enjoy the convenience brought by Natural Language Processing because the NLP technology can increase your productivity and simplify your working process.

To make the computer understand the natural language like a human, Natural Language Processing applies many techniques. It uses AI to receive the information input from the real world and process the information. Then NLP tries to use a way that the computer can understand to make sense of the information. Just like a human, the Natural Language Processing technology lets computers get information by keyboard and microphone. Then, your computer will convert the information to code that it can understand and process.

Thus, with NLP technology, you don't have to use a specific language to contact your computer or mobile phone. You can just speak or input your questions or thoughts, like contacting a human, and the software can understand and provide the information that you need.

Part 2. Top 3 NLP Technologies

Natural Language Processing has developed for more than 50 years and become more mature because of the development of the AI technology now. As we talked about above, NLP technology is used in many industries. So, this part will introduce the 3 most-used technologies of NLP to you: text embeddings, machine translation, and dialogue and conversations.

Text Embeddings

Text embeddings are necessary and important in Natural Language Processing. As numerical representations of text, they can capture and understand words or phrases' meanings and relationships. With the text embeddings technology, when you provide a piece of text to a program, your text will be projected into a high-dimensional latent space. And in this space, a vector or a sequence of numbers will represent your text's position. The distance between 2 embeddings is based on the similarity of 2 original format inputs' semantic meanings. So, the vector space is smaller, and the word's meanings are more similar. Sparse and dense are the 2 main embedding techniques of vectorizing text.

As for the uses of text embeddings, you can find this technology in many fields, including machine translation, text classification, text generation, information retrieval, and more.

Machine Translation

In Natural Language Processing, Machine Translation or MT is a technique that translates one natural language to another one automatically. And this technology can preserve the meaning and fluency of the original text during the translation process. Combined with computing linguistics, machine learning, and deep learning, NLP enables the program to understand your text or audio as humans do and translate it automatically.

The main methods in Machine Translation are rule-based machine translation, statistical machine translation, neural machine translation, and hybrid machine translation. Rule-based machine translation lets the software parse your text, generate a transitional description, and convert the representation into another language based on grammar rules. Different from RBMT, statistical machine translation relies on machine learning to translate your text instead of linguistic rules. As for neural machine translation, this approach imitates the human brain to process and connect resources for translating. Hybrid machine translation combines multiple machine translation models into one program.

Dialogue and Conversations

Inspired by human chatting in daily life, in Natural Language Processing, the dialogue and conversations technology enables you to obtain information by speaking and talking with tools, like ChatGPT, Gemini, Copilot, etc. Also, it is used in chatbots and voice assistants. When you input your questions or thoughts into these tools, they can identify and understand automatically and generate answers for you. Besides, if you need a person to talk to you, tools that apply the dialogue and conversations technique can offer emotional value too. This technology can play a suitable role in the conversation with you.

Part 3. What Are Algorithms for Natural Language Processing

Algorithms for Natural Language Processing are mathematical formulas. These algorithms are complex and used to train computers for understanding and processing natural language of humans. They use various techniques to let machines make sense of humans' words easily, including keyword extraction, word clouds, sentiment analysis, text summarization, knowledge graphs, and more.

Part 4. Best Chatbot Tool That Applies NLP Technology
