What is Natural Language Processing

What is Natural Language Processing?

Natural Language Processing, NLP for short, is a way for computers to analyze, understand, and process the meaning of human language in an intelligent and useful way. By using NLP, developers can organize and structure knowledge to perform tasks such as automatic summarization, translation, named entity recognition, relationship extraction, sentiment analysis, speech recognition, and topic segmentation.

NLP is used to analyze text so that machines can understand how humans speak. This human-computer interaction enables real-world applications such as automated text summarization, topic extraction, and more. It is especially widely used for text mining, machine translation, and automated question answering.

Human language is rarely precise or simply spoken. Understanding it means understanding not only the words, but also the concepts and how they are connected in order to make sense of them. The ambiguity of language is what causes the most difficulty for a computer to understand.


What can developers use Natural Language Processing algorithms for?

Typically, the Natural Language Processing-algorithms on machine learning algorithms. Instead of manually programming large sets of rules, NLP can rely on machine learning to automatically learn rules. This is made possible by analyzing a set of examples (i.e., a large corpus, like a book, down to a collection of sentences) and drawing a conclusion. In general, the more data that is analyzed, the more accurate the model will be.

  • Summarize blocks of text to extract the most important and central ideas of a text while ignoring irrelevant information.
  • Create a chat bot.
  • Automatic generation of Keyword-tags from content using AutoTag.
  • Identify the type of extracted entity, e.g. a person, place or organization.
  • Use mood analysis to identify the mood of a text sequence, from very negative to neutral to very positive.
  • Reduce words to their root or stem with PorterStemmer.

What is Natural Language Processing (NLP)? arrow icon in accordion
Natural Language Processing (NLP) is a subfield of Artificial Intelligence that deals with natural language processing. NLP includes techniques such as machine learning, language understanding algorithms, and machine translation that enable computers to understand and process natural language.
How does Natural Language Processing work? arrow icon in accordion
NLP uses extensive algorithms to convert natural language into structured data that can be understood by computers. This is done by analyzing speech input into tokens and syntax structures, which are then converted into a data structure. After that, the computer can then access this structure to understand the meaning behind the input.
What is Natural Language Processing used for? arrow icon in accordion
NLP is widely used to understand the meaning behind natural language input and perform actions based on it. For example, it can be used to train chatbots, for automatic responses in text messages, to understand customer queries, to analyze the content of text documents, or to provide automated translation services.
How does NLP help with text analysis? arrow icon in accordion
NLP algorithms help with text analysis by converting text into structured data. This allows the computer to understand the text more easily, resulting in improved text analysis. NLP algorithms can be used, for example, to identify language in a text or to extract keywords that serve as the basis for further analysis.
Are machine learning and NLP used together? arrow icon in accordion
Yes, machine learning and NLP are often used together. Machine learning can be used to train and improve NLP algorithms by training them on large amounts of data. Machine learning can also be used to build models that allow the computer to respond to new contexts and improve the performance of the NLP system.
What types of algorithms are used in NLP? arrow icon in accordion
Various algorithms are used in NLP, including machine learning, pattern recognition, machine translation algorithms, and text analysis algorithms. Each of these algorithms has a specific purpose and can be used for different tasks in NLP.
How are NLP algorithms trained? arrow icon in accordion
NLP algorithms are usually trained using machine learning. In this process, algorithms are fed a set of training data and then optimized based on the results they produce. This process is repeated until the algorithm achieves the desired performance.
What is the NLP pipeline? arrow icon in accordion
The NLP pipeline is a concept that describes the various steps required to process natural language. It starts with the input of text, followed by tokenization to divide the input into individual words and smaller parts. This is followed by the morphological process, which involves analyzing the words and their structure. This is followed by the syntactic process, where words are processed according to their role in a sentence. After the syntactic process comes the process of semantics, in which the meaning of the words is decoded.
What components are required for NLP? arrow icon in accordion
NLP requires a computational system, a text source, a source language, and a target language. The text source can be text documents, audio or video recordings, or similar sources. The source text must be inserted into a computational system so that the NLP algorithms can process it. Then, the text must be translated into the target language and the results must be checked and validated.
What are the advantages of NLP? arrow icon in accordion
The biggest advantage of NLP is that it enables computers to understand natural language much better. This opens up entirely new applications for computers, from automatic translation and simple queries to complex chatbots and text analytics. NLP algorithms can also be used to improve the efficiency of computer and web applications and enhance usability.
