How Computers Understand Human Language
Giant update:Ive written a new book based on these articles! It not only expands and updates all my articles, but it has tons of brand new content and lots of hands-on coding projects. Check it out now!
Computers are great at working with structured data like spreadsheets and database tables. But us humans usually communicate in words, not in tables. Thats unfortunate for computers.
A lot of information in the world is unstructured raw text in English or another human language. How can we get a computer to understand unstructured text and extract data from it?
Natural Language Processing, or NLP, is the sub-field of AI that is focused on enabling computers to understand and process human languages. Lets check out how NLP works and learn how to write programs that can extract information out of raw text using Python!
Note: If you dont care how NLP works and just want to cut and paste some code, skip way down to the section called Coding the NLP Pipeline in Python.
Extracting Meaning From Text Is Hard
The process of reading and understanding English is very complex and thats not even considering that English doesnt follow logical and consistent rules. For example, what does this news headline mean?
Environmental regulators grill business owner over illegal coal fires.
Are the regulators questioning a business owner about burning coal illegally? Or are the regulators literally cooking the business owner? As you can see, parsing English with a computer is going to be complicated.
Doing anything complicated in machine learning usually means building a pipeline. The idea is to break up your problem into very small pieces and then use machine learning to solve each smaller piece separately. Then by chaining together several machine learning models that feed into each other, you can do very complicated things.
And thats exactly the strategy we are going to use for NLP. Well break down the process of understanding English into small chunks and see how each one works.

Adopting Nlp In The Contact Center
A single statement in a human conversation possesses rich data, full of potential meaning and variation. Yet, computer systems often struggle to manage it.
For example, standalone keywords, sentence structure, underlying sentiment, and customer metadata must be organized, structured, and arranged to produce reliable analysis.
Multiply this by thousands of customers speaking to agents on dozens of channels daily. That is a massive volume of data to parse.
Typically, companies lack adequate in-house computing infrastructure and an absence of data scientists.
There are, of course, open-source or commercial NLP libraries available. But building one from scratch is a significant, time-consuming effort. Thats why most companies partner with NLP consulting companies with domain-specific expertise.
Several companies offer advanced tools using NLP for contact centers. These include:
- Chattermill An AI and NLP-powered feedback analysis solution, including CX automation and sophisticated dashboards.
- Ascribe A CX analysis and visualization company using Ai and NLP also offers AI project acceleration solutions.
- Wootric A customer experience management and analytics software solution powered by NLP, including text and sentiment analytics.
Yet, most leading contact center providers today, like Genesys, NICE, and Talkdesk, incorporate NLP technology into their conversational offerings, making their chatbots more intuitive and accurate.

Sometimes major shifts happen virtually unnoticed. On May 5, IBMannounced Project CodeNet to very little media or academic attention.
CodeNet is a follow-up to ImageNet, a large-scale dataset of images and their descriptions the images are free for non-commercial uses. ImageNet is now central to the progress of deep learning computer vision.
CodeNet is an attempt to do for Artificial Intelligence coding what ImageNet did for computer vision: it is a dataset of over 14 million code samples, covering 50 programming languages, intended to solve 4,000 coding problems. The dataset also contains numerous additional data, such as the amount of memory required for software to run and log outputs of running code.
Nlp: The Art Of Understanding Human Communication
A wide range of technologies used in understanding and interacting with humans is referred to as natural language processing in todays world. The grammar analysis of a sentence, also known as puns, is an important part of many NLP tasks, including machine translation, text recognition, and natural language understanding. Because human communication is often ambiguous, it is difficult for natural language processing to process sentiment. In the sentence Tom ate an apple, the word apple could be used to indicate both an actual apple and an eating action. Adding to the complexity, speakers may spell the same word differently in order to make it more difficult. In order for an algorithm to parse a sentence inNLP, it must first break it down into constituent words. This task entails looking for rules that apply to the example sentences grammar and looking for grammar rules that apply to the parsed language. As shown below, a noun is the subject, the object, or the direct object of a verb. For example, the word apple can be considered a noun and can be the subject, the object, or the direct object of the verb. The ability to proofread complex tasks, such as machine translation and text recognition, is a critical component of the proofread system. By understanding the grammar of a language, natural language processing algorithms can make it easier to convert human sentences to computer code.

Some Natural Language Processing Programming Languages
Semantic and syntax analysis forms a significant part of natural language processing, as does the development of NLP algorithms based on machine learning principles. Some of the core computing languages used in natural language processing have a data science and statistical analysis focus.
MATLAB, a fourth-generation programming language, and platform often used in representing and working with matrices. A high-performance technical computing language, MATLAB typically performs the mathematical computation and algorithm development underlying natural language processing operations.
The programming language R uses statistical methods and graphs to play a role in investigating big data, supporting NLP research and performing computationally intense learning analytics. A considerable number of natural language processing algorithms have been developed in R, making the language an ideal tool for NLP modeling and prototypes.
Natural Language Processing Examples
We dont regularly think about the intricacies of our own languages. Its an intuitive behavior used to convey information and meaning with semantic cues such as words, signs, or images. Its been said that language is easier to learn and comes more naturally in adolescence because its a repeatable, trained behaviormuch like walking. And language doesnt follow a strict set of rules, with so many exceptions like I before E except after C. What comes naturally to humans, however, is exceedingly difficult for computers with the amount of unstructured data, lack of formal rules, and absence of real-world context or intent. Thats why machine learning and artificial intelligence are gaining attention and momentum, with greater human dependency on computing systems to communicate and perform tasks. And as AI and get more sophisticated, so will Natural Language Processing . While the terms AI and NLP might conjure images of futuristic robots, there are already basic examples of NLP at work in our daily lives. Here are a few prominent examples.

Automate Customer Support Tasks
Businesses are using NLP models to automate tedious and time-consuming tasks in areas like customer service. This results in more efficient processes, and agents with more time to focus on what matters most: delivering outstanding support experiences.
Customer service automation powered by NLP includes a series of processes, from routing tickets to the most appropriate agent, to using chatbots to solve frequent queries. Here are some examples:
Text classification models allow companies to tag incoming support tickets based on different criteria, like topic, sentiment, or language, and route tickets to the most suitable pool of agents. An e-commerce company, for example, might use a topic classifier to identify if a support ticket refers to a shipping problem, missing item, or return item, among other categories.
Classifiers can also be used to detect urgency in customer support tickets by recognizing expressions such as ASAP, immediately, or right now, allowing agents to tackle these first.
Heres an example of how you can use MonkeyLearns urgency detector to spot an issue that needs to be solved right away
Basic Nlp To Impress Your Non
The main drawbacks we face these days with NLP relate to the fact that language is very tricky. The process of understanding and manipulating language is extremely complex, and for this reason it is common to use different techniques to handle different challenges before binding everything together. Programming languages like Python or R are highly used to perform these techniques, but before diving into code lines , its important to understand the concepts beneath them. Lets summarize and explain some of the most frequently used algorithms in NLP when defining the vocabulary of terms:

Sample Of Nlp Preprocessing Techniques
Tokenization: Tokenization splits raw text into a sequence of tokens, such as words or subword pieces. Tokenization is often the first step in an NLP processing pipeline. Tokens are commonly recurring sequences of text that are treated as atomic units in later processing. They may be words, subword units called morphemes , or even individual characters.
Bag-of-words models: Bag-of-words models treat documents as unordered collections of tokens or words . Because they completely ignore word order, bag-of-words models will confuse a sentence such as dog bites man with man bites dog. However, bag-of-words models are often used for efficiency reasons on large information retrieval tasks such as search engines. They can produce close to state-of-the-art results with longer documents.
Stop word removal: A stop word is a token that is ignored in later processing. They are typically short, frequent words such as a, the, or an. Bag-of-words models and search engines often ignore stop words in order to reduce processing time and storage within the database. Deep neural networks typically do take word-order into account and do not do stop word removal because stop words can convey subtle distinctions in meaning .
Large Volumes Of Textual Data
Natural language processing helps computers communicate with humans in their own language and scales other language-related tasks. For example, NLP makes it possible for computers to read text, hear speech, interpret it, measure sentiment and determine which parts are important.
Todays machines can analyze more language-based data than humans, without fatigue and in a consistent, unbiased way. Considering the staggering amount of unstructured data thats generated every day, from medical records to social media, automation will be critical to fully analyze text and speech data efficiently.

How Does It Work
The varying interpretations of NLP make it hard to define. It is founded on the idea that people operate by internal maps of the world that they learn through sensory experiences.
NLP tries to detect and modify unconscious biases or limitations of an individuals map of the world.
NLP is not hypnotherapy. Instead, it operates through the conscious use of language to bring about changes in someones thoughts and behavior.
For example, a central feature of NLP is the idea that a person is biased towards one sensory system, known as the preferred representational system or PRS.
Therapists can detect this preference through language. Phrases such as I see your point may signal a visual PRS. Or I hear your point may signal an auditory PRS.
An NLP practitioner will identify a persons PRS and base their therapeutic framework around it. The framework could involve rapport-building, information-gathering, and goal-setting with them.
Determining the effectiveness of NLP is challenging for several reasons.
NLP has not been subject to the same standard of scientific rigor as more established therapies, such as cognitive behavioral therapy or CBT.
The lack of formal regulation and NLPs commercial value mean that claims of its effectiveness can be anecdotal or supplied by an NLP provider. NLP providers will have a financial interest in the success of NLP, so their evidence is difficult to use.
Furthermore, scientific research on NLP has produced mixed results.
What Are Some Common Applications Of Natural Language Programming
There are many applications for natural language programming in AI. Some common applications include:
1. Natural language processing: This is perhaps the most common application of natural language programming in AI. Natural language processing algorithms are used to process and interpret human language. This can be used for tasks such as automatic translation, text classification, and sentiment analysis.
2. Dialogue systems: Dialogue systems, or chatbots, are another common application of natural language programming. These systems are used to simulate human conversation, and can be used for customer service, information retrieval, and other tasks.
3. Virtual assistants: Virtual assistants are another type of AI application that relies heavily on natural language processing. These assistants can perform tasks such as scheduling appointments, sending emails, and providing customer support.
4. Predictive analytics: Predictive analytics is another area where natural language processing can be used. This type of AI is used to make predictions about future events, trends, and behaviours.
5. Robotics: Robotics is another area where natural language programming can be used. Robots can be programmed to understand and respond to human commands and requests. This can be used for tasks such as manufacturing, logistics, and search and rescue.

Syntactic And Semantic Analysis
Syntactic analysis and semantic analysis are the two primary techniques that lead to the understanding of natural language. Language is a set of valid sentences, but what makes a sentence valid? Syntax and semantics.
Syntax is the grammatical structure of the text, whereas semantics is the meaning being conveyed. A sentence that is syntactically correct, however, is not always semantically correct. For example, cows flow supremely is grammatically valid but it doesnt make any sense.
B: Finding Noun Phrases
So far, weve treated every word in our sentence as a separate entity. But sometimes it makes more sense to group together the words that represent a single idea or thing. We can use the information from the dependency parse tree to automatically group together words that are all talking about the same thing.
For example, instead of this:
We can group the noun phrases to generate this:
Whether or not we do this step depends on our end goal. But its often a quick and easy way to simplify the sentence if we dont need extra detail about which words are adjectives and instead care more about extracting complete ideas.

Lets look at a piece of text from Wikipedia:
London is the capital and most populous city of England and the United Kingdom. Standing on the River Thames in the south east of the island of Great Britain, London has been a major settlement for two millennia. It was founded by the Romans, who named it Londinium.
This paragraph contains several useful facts. It would be great if a computer could read this text and understand that London is a city, London is located in England, London was settled by Romans and so on. But to get there, we have to first teach our computer the most basic concepts of written language and then move up from there.
