Companies are filled with unstructured data, and it is impossible for them to analyze and process all this data without the help of NLP. Read this article to learn what Natural Language Processing is and how it can make business more efficient, discover popular NLP techniques and examples, and finally, We’ll show you how to get started with easy-to-use NLP tools.
What is Natural Language Processing?
Natural language processing is a subfield of artificial intelligence. It helps machines process and understand human language, so they can perform repetitive tasks automatically. Examples include machine translation, summarization, ticket classification, and spelling.
Take sentiment analysis, for example, which uses natural language processing to detect emotions in text. This classification task is one of the most common NLP tasks, and is often used by companies to automatically detect brand sentiment on social media. Analyzing this can help Interactions can help brands discover pressing customer issues they need to respond to immediately, or monitor overall customer satisfaction.
Why is Natural Language Processing important?
One of the main reasons why NLP is so critical to businesses is that it can be used to analyze large amounts of text data, such as social media comments, customer support tickets, online reviews, news reports, and more.
All of this business data contains a wealth of valuable insights. NLP can quickly help companies figure out what those ideas are, and NLP does this by helping machines understand human language faster, more accurately, and more consistently than human factors.
NLP tools process data in real time, 24/7, and apply the same standards to all of your data, so you can ensure the results you receive are accurate and free of inconsistencies. Once NLP tools understand what part of the text is, Even measuring things like sentiment, companies can begin to prioritize and organize their data in a way that fits their needs and aligns with their goals.
Natural Language Processing Challenges
While there are many challenges in NLP, its huge benefits for companies make it a successful investment, however, it is important to know what these challenges are before starting NLP, as human language is complex, ambiguous, unstructured and diverse, and there are more Of the 6,500 languages in the world, each has its own grammatical and semantic rules, and even humans struggle to understand language, so in order for machines to understand natural languages, they must first turn into something they can interpret.
In natural language processing, syntax and semantic analysis are key to understanding the grammatical structure of text and determining how words relate to each other in a given context, but turning text into something that machines can process is still complex, as data scientists need to teach NLP tools to look at what Behind definitions and word order, to understand context and ambiguity in words and other complex concepts associated with human language.
How does natural language processing work?
In natural language processing, human language is separated into parts so that the grammatical structure of sentences and the meanings of words can be analyzed and understood in context. This helps computers read and understand spoken or written text in the same way as humans.
Here are some of the basic NLP preprocessing tasks that data scientists need to perform before NLP tools can understand human language:
- Encoding: In which text is broken down into smaller semantic units or individual sentences.
- Marking part of speech: encoding words as nouns, verbs, adjectives, adverbs, pronouns…etc.
- Derivation: Unifying words by reducing them to their root forms.
- Remove redundant words: Filter common words that add little or no unique information, for example, prepositions.
Only then can the NLP tools convert the text into something a machine can understand, and the next step is to build the NLP algorithm.
Natural language processing algorithms
Once your data has been processed, it’s time to move on to the next step, which is building the NLP algorithm, and training it so it can interpret NLP and perform specific tasks. There are two main algorithms you can use to solve NLP problems:
- Grammar-based approach: Grammar-based systems rely on handcrafted grammars, which must be created by experts in linguistics or knowledge engineers. This was the first approach to formulating natural language processing algorithms and is still used today.
- Machine learning algorithms: On the other hand, machine learning models rely on statistical methods and learn to perform tasks after providing them with examples, which are called “training data”.
The biggest advantage of machine learning algorithms is their ability to learn on their own. You don’t need to manually define rules. Instead, machines learn from past data so they can make a prediction on their own, allowing for more flexibility.
Machine learning algorithms are fed training data and expected output (“tags”) to train the machines to make associations between specific inputs and their corresponding outputs. Visual, that is, texts that have not yet been written.
Examples of Natural Language Processing
Natural Language Processing helps you perform a variety of tasks, from classifying texts and extracting related data, to translating texts from one language to another and summarizing long pieces of content.
- text classification
- Text extraction
- automatic translation
- Subject Modeling
- natural language generation
