Natural Language Processing NLP What is it and how is it used?

examples of natural language processing

This is what a computer is trying to do when we want it to do key word analysis; identify the important words and phrases to get the context of the text and extract the key messages. Overall, the steps involved in NLP can be complex and involve a wide range of techniques and tools. However, advances in machine learning (ML) and AI are making it easier than ever to develop powerful NLP systems that can analyze and interpret human language with a high degree of accuracy. Natural language processing (NLP) is a branch of artificial intelligence (AI) that analyzes human language and lets people communicate with computers. The NLP system is like a dictionary that translates words into specific instructions that a computer can then carry out. Natural Language techniques are not based on computers as having any real understanding of natural language – this is something computers cannot currently do.

It is often used on text data by businesses so that they can monitor their customers’ feelings towards them and better understand customer needs. In 2005 when blogging was really becoming part of the fabric of everyday life, a computer scientist called Jonathan Harris started tracking how people were saying they felt. The result was We Feel Fine, part infographic, part work of art, part data science. This kind of experiment was a precursor to how valuable deep learning and big data would become when used by search engines and large organisations to gauge public opinion. NLP works by teaching computers to understand, interpret and generate human language. This process involves breaking down human language into smaller components (such as words, sentences, and even punctuation), and then using algorithms and statistical models to analyze and derive meaning from them.

tl;dr – Key Takeaways

Natural Language Understanding seeks to intuit many of the connotations and implications that are innate in human communication such as the emotion, effort, intent, or goal behind a speaker’s statement. It uses algorithms and artificial intelligence, backed by large libraries of information, to understand our language. Natural language processing has two main subsets – natural language understanding (NLU) and natural language generation (NLG). The goal of NLP is to enable humans to communicate with computers using natural human language and vice-versa. NLP does just that through a complex combination of analytical models and methods.

Researchers should also be encouraged to address challenges in multi-modal interfaces (for example, by exploring and exploiting the links between language and vision). The participants could only use common nouns on various topics (that is, proper nouns, neologisms, for example, medical terms could https://www.metadialog.com/ not be entered). There were only 4 minutes to complete the task, but most participants coped in less than 2 minutes. During the study, the participants were to name 10 words which differed in meaning, 7 of which were measured (since many had errors in 1-3 words) in pairs using NLP methods.

Step 3: Calculate and Pay the Total Automatically

Speech recognition goes hand in hand with the other NLP concept – question answering. Question answering tasks allow us to determine answers to the questions given in a natural language. Moreover, NLP allows us not only to integrate voice understanding into devices and sensors. Thanks to machine translation capabilities, it enables localization features. And with the level of market globalization we experience today, localization goes even beyond translation and unlocks the benefits of transcreation (creative translation).

RNNs have neural units that are capable of remembering what they have processed so far. This memory is temporal, and the information is stored and updated with every time step as the RNN reads the next word in the input. Figure 1-13 shows an unrolled RNN and how it keeps track of the input at different time steps. Context is how various parts in a language come together to convey a particular meaning. Context includes long-term references, world knowledge, and common sense along with the literal meaning of words and phrases.

GATE is used for building text extraction for closed and well-defined domains where accuracy and completeness of coverage is more important. As an example, JAPE and GATE were used to extract information on pacemaker implantation procedures from clinical reports [15]. Figure 1-10 shows the GATE interface along with several types of information highlighted in the text as an example of a rule-based system. Common examples of natural language processing in real-world NLP projects is a case of semi-supervised learning, where we have a small labeled dataset and a large unlabeled dataset. Semi-supervised techniques involve using both datasets to learn the task at hand. Last but not least, reinforcement learning deals with methods to learn tasks via trial and error and is characterized by the absence of either labeled or unlabeled data in large quantities.


The technology extracts meaning by breaking the language into words and deriving context from the relationship between these words. In this way do we use NLP to index data and segment data into a specific group or class with a high degree of accuracy. These segments can include sentiment, intent, and pricing information among others. The use of machine learning requires large volumes of training data to function effectively. The more information a natural language processing software is trained on, the smarter and more efficient it becomes. While advanced technology such as neural networks and deep learning allow natural language processing techniques to function effectively, there is still huge room for growth [14].

Sentiment analysis and market intelligence

So if you are someone who tends to swear like a trooper, then perhaps you should take a look at the amount of profanity used. Then, you could compare the number of words used and each comic’s unique speed of delivery, whose data may be presented using simple bar charts. In emergency situations, such as a ship in distress, it is critical to quickly locate the vessel and understand the nature of the emergency.

What is an example of a natural language interaction?

Some of the widely used ones are Siri, Alexa, and Google Assistant. These also use keywords to activate natural language recognition, such as the use of ‘Hey Google’ by Google Assistant. Text recognition is another example of NLI. Online chatbots are one of the most commonly found examples of text-based NLI.

The algorithm then learns how to classify text, extract meaning, and generate insights. Typically, the model is tested on a validation set of data to ensure that it is performing as expected. NLP algorithms use statistical models to identify patterns and similarities between the source and target languages, allowing them to make accurate translations. More recently, deep learning techniques such as neural machine translation have been used to improve the quality of machine translation even further.

Who uses NLP techniques?

Mental health professionals use NLP by itself or with other types of therapy, like talk therapy or psychoanalysis, to help treat depression and anxiety. It can be used to treat phobias in particular, as well as other expressions of anxiety such as panic attacks.
