What would your reaction be if we told you that you were most likely in contact with some form of NLP? You’d probably be curious and excited!
You may probably guess what it is if you’ve ever used Google Assistant or Amazon Alexa. Both are based on natural language processing, transforming a voice into letters, sounds, and concepts.
If you’re interested in learning more about NLP and becoming a master, codefather.tech is glad to tell you that you’ve arrived at the correct place! However, in order to better comprehend the term NLP, let us delve deeper into the concept and clear up any misunderstandings.
What is NLP?
NLP, or natural language processing, is a subset of artificial intelligence (AI) that deals with computers’ ability to comprehend spoken and written language in a manner similar to that of humans. Sounds crazy, huh?
It blends linguistics and computer programming to investigate the principles and structure of language and to develop intelligent systems capable of comprehending, processing, and extracting value from text and speech.
It is utilized in computer software that translates text between languages, responds to spoken requests, and summarizes large volumes of information quickly—even instantly.
NLP has undoubtedly already been employed by you in the form of bots for customer service, apps, voice-activated navigation systems, and much more.
NLP is being more widely employed in corporate solutions to assist firms to streamline operations, improve the performance of employees, and simplify certain systems and processes.
How Does NLP Function?
Natural language processing refers to a plethora of approaches to understanding natural speech, including statistical and deep learning approaches, as well as rules-based and algorithmic approaches.
Basic NLP tasks include parsing, tokenization, part-of-speech identification, and semantic link detection. If you’ve ever graphed sentences in primary school, you’ve definitely done these tasks manually before.
NLP activities, in general, break down language into smaller, essential components, attempt to comprehend links between the pieces, and investigate how the pieces interact to form meaning.
These tasks are frequently employed in higher-level NLP capabilities, such as:
- Content classification: a document summary that is linguistically based.
- Extraction from context: streamline the extraction of processed data from text-based sources.
- Machine translation: text or voice is automatically converted between languages.
- Summarization of documents: plot summaries of large portions of text can be generated automatically.
- Topic discovery: capture the meaning and topics of text collections accurately.
- Conversion of speech to text: voice commands are converted to textual content and vice versa.
Tasks in Natural Language Processing
Writing software that effectively understands the desired meaning of text or voice input is exceedingly difficult since human language is replete with ambiguities—synonyms, homonyms, metaphors, and sarcasm are all part of that!
However, several NLP activities help the machine understand what it’s absorbing by breaking down human text and speech input in ways that the computer can understand. The following are some of these responsibilities:
Speech Recognition
The task of successfully translating voice input into written data is known as speech recognition or speech-to-text. Any program that takes voice commands or responds to spoken questions requires speech recognition.
The way humans speak—quickly, slurring words together, with varied stress and tone, in a variety of accents, and frequently using improper grammar—makes speech recognition particularly difficult.
Disambiguation of Terms
It is the process of determining the meaning of a word with numerous meanings using a semantic analysis technique to discover which word makes the most sense in the current context.
It might, for example, recognize when a specific verb is used to perform an action on a person, place, or item.
Resolution of Co-References
It is the task of determining whether or not two words relate to the same thing. The most basic example is determining who or what a pronoun refers to (for example, ‘he’ = ‘John’), but it can also include detecting a simile or allusion in the text.
Analyzing Sentiment
It tries to extract subjective aspects from text, such as opinions, feelings, irony, bewilderment, and suspicion.
Speech Tagging
The method used to determine the part of speech of a specific word or piece of writing relying on its use and context is known as speech tagging, or grammatical tagging.
In distinct sentences, part of speech tagging identifies a verb and a noun. For example, “I’ll make a strategy” and “What car do you have?”
Where Does NLP Come Into Play?
In many contemporary real-world applications, NLP lies at the heart of machine intelligence. Let’s have a look at which industries it applies to the most:
Machine Translation
Google Translate is an excellent illustration of this – and we’re confident that everyone has used it at least once.
A really useful translation software, on the other hand, entails more than simply changing letters in one language with letters in another – it needs to precisely capture the message and mood of the input language and convert it to text in the output language that has the same interpretation and desired impact.
Translating content to one language and then back to the original is a wonderful approach to test any machine translation algorithm – if the text remains unchanged, we’re dealing with a highly powerful NLP technology.
Spam Detection
Although you would not consider spam detection as an NLP tool, in fact, it is. The top spam detection solutions examine emails for language that typically suggests fraud or scamming.
Overuse of financial words, typical grammar errors, intimidating language, improper urgency, misspelled firm names, and other signs can all be used as indicators. Spam detection stands as one of a few mostly solved NLP challenges.
Text Summarization
Text summarization makes use of NLP techniques to absorb large amounts of digital text and provide summaries and overviews for indices, research databases, and busy users who don’t have time to read the full text.
To provide valuable context and conclusions to summaries, the finest text summarizing technologies use semantic thinking and natural language generation (NLG).
Social Media
NLP has become an indispensable commercial tool for revealing hidden data insights from social media platforms.
Sentiment analysis may derive attitudes and feelings in response to items, services, and events by analyzing the language used in social media postings, answers, comments, and more–information that organizations can utilize in product design, ad campaigns, and more.
Chatbots and Virtual Agents
Text-to-speech and natural language generation are used by virtual agents like Amazon’s Alexa to spot patterns in voice control and react with the appropriate course of action or give friendly advice.
In regard to written text entries, chatbots work in the same way. The finest of these also learn to understand contextual hints in human queries and utilize them to improve their responses or possibilities over time.
NLP Methods and Instruments
There are a variety of NLP tools and methodologies available. Here are some of the most common ones.
The Natural Language Toolkit and Python
For tackling specialized NLP tasks, the Python programming language provides a large choice of tools and frameworks. Many of them can be found in the Natural Language Toolkit (NLTK), which is an open-sourced collection of libraries, systems, and educational resources for developing NLP programs.
The NLTK supports a wide range of NLP tasks and their subtasks, including textual analysis, lexical analysis, stemming, and text categorization. Additionally, it provides libraries for building tools like semantic analysis, which enables users to make logical deductions from text-based data.
Deep Learning, Statistical NLP, and Machine Learning
The original NLP algorithms were rule-based systems, which while capable of handling specific NLP tasks cannot readily be expanded to handle an endless flow of exceptions or increasing amounts of verbal and written input.
In order to efficiently extract, classify, and label different inputs from speech and text, statistical natural language processing combines sophisticated algorithms with various computational systems. Each potential interpretation is then given a statistical likelihood value.
NLP systems can now “learn things” as they go by using deep learning techniques and learning strategies focused on convolutional neural networks (CNNs) and recurrent neural networks (RNNs), which enable them to obtain ever-more precise explanations from vast amounts of disorganized, unrecognizable content and speech data sets.
Reasons to Become a Natural Language Processing Master
Do you search for your favorite song yourself or do you ask Alexa to do it for you? The second choice is currently preferred by a large number of people. Virtual assistants such as Alexa and Cortana are becoming more and more integrated into our daily lives.
While interacting with Alexa appears to be quite handy, there is a complex mechanism at work behind the scenes that most people are unaware of – natural language processing. It is a significant type of Artificial Intelligence (AI) that has been in use for a long time.
When applied, NLP takes numerous forms, but at its heart, it helps machines understand and communicate with human speech. Although NLP is not a new science, it has just lately become practical.
And because it has grown more practical, many of us who choose to study NLP will reap significant benefits! Here are some of the most compelling reasons to begin studying NLP.
It Has Various Applications
One of the most popular uses of NLP is virtual assistants. Other domains where NLP has been used include sentiment analysis, text categorization, virtual agents, consumer experience, and voice to text conversion, and vice versa.
All of these applications have the same goal: to take basic language input and alter it using technology and linguistics to generate useful insights.
NLP is beneficial for detecting fraud, control and risk management, asset management, proactive maintenance, and even customer service in industries such as banking, insurers, healthcare, commerce, and media.
There is a Lot of Demand
Today, no business can afford to overlook digital transformation – every company is attempting to harness the potential of AI, whether for advertising campaigns, banking services, or providing a customized experience to users.
Companies are analyzing unstructured data to detect trends and make data-driven choices, and text data makes up a substantial component of that data. As a result, people with experience in natural language processing (NLP) will be in great demand for work requiring text analytics.
It isn’t Going Anywhere
NLP is already assisting people with their day-to-day tasks, while not being as well-known as Machine Learning.
The adoption of NLP in the future will be driven by the increasing functionality of smartphones, the use of smart devices, and the digitization of more ordinary human activities via Big Data.
When used in conjunction with IoT applications, NLP could make it easier for humans to manage smart appliances using their voices. Businesses would use it to better manage data, deliver a better customer experience, and so on.
Clearly, learning NLP and enhancing one’s AI career is useful for professionals and it may be one of the most sought-after skills in the near future!
