What is natural language processing?Natural language processing, or NLP, is currently one of the major successful application areas for deep learning, despite stories about its failures. The overall goal of natural language processing is to allow computers to make sense of and act on human language. We'll break that down further in the next section.
Historically, natural language processing was handled by rule-based systems, initially by writing rules for, e.G., grammars and stemming. Aside from the sheer amount of work it took to write those rules by hand, they tended not to work very well.
Why not? Let's consider what should be a simple example, spelling. In some languages, such as Spanish, spelling really is easy and has regular rules. Anyone learning English as a second language, however, knows how irregular English spelling and pronunciation can be. Imagine having to program rules that are riddled with exceptions, such as the grade-school spelling rule "I before E except after C, or when sounding like A as in neighbor or weigh." As it turns out, the "I before E" rule is hardly a rule. Accurate perhaps 3/4 of the time, it has numerous classes of exceptions.
After pretty much giving up on hand-written rules in the late 1980s and early 1990s, the NLP community started using statistical inference and machine learning models. Many models and techniques were tried; few survived when they were generalized beyond their initial usage. A few of the more successful methods were used in multiple fields. For example, Hidden Markov Models were used for speech recognition in the 1970s and were adopted for use in bioinformatics—specifically, analysis of protein and DNA sequences—in the 1980s and 1990s.
Phrase-based statistical machine translation models still needed to be tweaked for each language pair, and the accuracy and precision depended mostly on the quality and size of the textual corpora available for supervised learning training. For French and English, the Canadian Hansard (proceedings of Parliament, by law bilingual since 1867) was and is invaluable for supervised learning. The proceedings of the European Union offer more languages, but for fewer years.
In the fall of 2016, Google Translate suddenly went from producing, on the average, "word salad" with a vague connection to the meaning in the original language, to emitting polished, coherent sentences more often than not, at least for supported language pairs such as English-French, English-Chinese, and English-Japanese. Many more language pairs have been added since then.
That dramatic improvement was the result of a nine-month concerted effort by the Google Brain and Google Translate teams to revamp Google Translate from using its old phrase-based statistical machine translation algorithms to using a neural network trained with deep learning and word embeddings using Google's TensorFlow framework. Within a year neural machine translation (NMT) had replaced statistical machine translation (SMT) as the state of the art.
Was that magic? No, not at all. It wasn't even easy. The researchers working on the conversion had access to a huge corpus of translations from which to train their networks, but they soon discovered that they needed thousands of GPUs for training, and that they would need to create a new kind of chip, a Tensor Processing Unit (TPU), to run Google Translate on their trained neural networks at scale. They also had to refine their networks hundreds of times as they tried to train a model that would be nearly as good as human translators.
Natural language processing tasksIn addition to the machine translation problem addressed by Google Translate, major NLP tasks include automatic summarization, co-reference resolution (determine which words refer to the same objects, especially for pronouns), named entity recognition (identify people, places, and organizations), natural language generation (convert information into readable language), natural language understanding (convert chunks of text into more formal representations such as first-order logic structures), part-of-speech tagging, sentiment analysis (classify text as favorable or unfavorable toward specific objects), and speech recognition (convert audio to text).
Major NLP tasks are often broken down into subtasks, although the latest-generation neural-network-based NLP systems can sometimes dispense with intermediate steps. For example, an experimental Google speech-to-speech translator called Translatotron can translate Spanish speech to English speech directly by operating on spectrograms without the intermediate steps of speech to text, language translation, and text to speech. Translatotron isn't all that accurate yet, but it's good enough to be a proof of concept.
Natural language processing methodsLike any other machine learning problem, NLP problems are usually addressed with a pipeline of procedures, most of which are intended to prepare the data for modeling. In his excellent tutorial on NLP using Python, DJ Sarkar lays out the standard workflow: Text pre-processing -> Text parsing and exploratory data analysis -> Text representation and feature engineering -> Modeling and/or pattern mining -> Evaluation and deployment.
Sarkar uses Beautiful Soup to extract text from scraped websites, and then the Natural Language Toolkit (NLTK) and spaCy to preprocess the text by tokenizing, stemming, and lemmatizing it, as well as removing stopwords and expanding contractions. Then he continues to use NLTK and spaCy to tag parts of speech, perform shallow parsing, and extract Ngram chunks for tagging: unigrams, bigrams, and trigrams. He uses NLTK and the Stanford Parser to generate parse trees, and spaCy to generate dependency trees and perform named entity recognition.
Sarkar goes on to perform sentiment analysis using several unsupervised methods, since his example data set hasn't been tagged for supervised machine learning or deep learning training. In a later article, Sarkar discusses using TensorFlow to access Google's Universal Sentence Embedding model and perform transfer learning to analyze a movie review data set for sentiment analysis.
As you'll see if you read these articles and work through the Jupyter notebooks that accompany them, there isn't one universal best model or algorithm for text analysis. Sarkar constantly tries multiple models and algorithms to see which work best on his data.
For a review of recent deep-learning-based models and methods for NLP, I can recommend this article by an AI educator who calls himself Elvis.
Natural language processing servicesYou would expect Amazon Web Services, Microsoft Azure, and Google Cloud to offer natural language processing services of one kind or another, in addition to their well-known speech recognition and language translation services. And of course they do—not only generic NLP models, but also customized NLP.
Amazon Comprehend is a natural language processing service that extracts key phrases, places, peoples' names, brands, events, and sentiment from unstructured text. Amazon Comprehend uses pre-trained deep learning models and identifies rather generic places and things. If you want to extend this capability to identify more specific language, you can customize Amazon Comprehend to identify domain-specific entities and to categorize documents into your own categories
Microsoft Azure has multiple NLP services. Text Analytics identifies the language, sentiment, key phrases, and entities of a block of text. The capabilities supported depend on the language.
Language Understanding (LUIS) is a customizable natural-language interface for social media apps, chat bots, and speech-enabled desktop applications. You can use a pre-built LUIS model, a pre-built domain-specific model, or a customized model with machine-trained or literal entities. You can build a custom LUIS model with the authoring APIs or with the LUIS portal.
For the more technically minded, Microsoft has released a paper and code showing you how to fine-tune a BERT NLP model for custom applications using the Azure Machine Learning Service.
Google Cloud offers both a pre-trained natural language API and customizable AutoML Natural Language. The Natural Language API discovers syntax, entities, and sentiment in text, and classifies text into a predefined set of categories. AutoML Natural Language allows you to train a custom classifier for your own set of categories using deep transfer learning.

6 Common Types of AI ModelsModels are the backbone of artificial intelligence, created using algorithms and massive data. These AI models are designed to learn from experiences, identify patterns, and draw conclusions.
Machine Learning ModelsMachine learning (ML) uses advanced mathematical models and algorithms to process large volumes of data and generate insights without human intervention. During AI model training, the ML algorithm is optimized to identify certain patterns or outputs from large datasets, depending on the tasks. The output from this training is called a machine learning model, which is usually a computer program with specific rules and data structures.
ML models can find patterns or make decisions from a previously unseen dataset and use various techniques to perform AI tasks such as natural language processing (NLP), image recognition, and predictive analytics. In NLP, ML models can analyze and recognize the intent behind sentences or combinations of words. Meanwhile, an ML image recognition model can learn how to identify and classify objects such as cars or dogs.
Machine learning frameworks often use software languages such as TensorFlow and PyTorch to deliver a usable model. TensorFlow, created by Google Brain, is ideal for both production and research environments since it is flexible and scalable. PyTorch is an open-source machine learning framework suitable for testing and research, built on top of the Torch library and the Python programming language.
The following are the main types of machine learning models:
Deep learning is a subset of machine learning that uses multilayered neural networks, called deep neural networks, to attempt to mimic the decision-making processes of the human brain. These models "learn" from large amounts of data and simulate how a human baby uses a network of neurons in their brains to take in information. Deep learning models rely on artificial neural networks, which include multiple layers that allow the system to process and reprocess data until it learns essential characteristics of the data it is analyzing. Models using deep learning architectures enable systems to cluster data and make predictions with remarkable accuracy.
The following are some of the most common deep learning architectures:
Natural language processing is a branch of computer science and AI that enables computers to comprehend, generate, and manipulate human language. It relies on computational linguistics based on statistical and mathematical methods that model human language use. Tools like navigation systems like automobiles, speech-to-text transition, chatbots, and voice recognition use NLP to process text or speech and extract meaning.
NLP techniques or tasks break down human text or speech into digestible parts that computer programs can understand. These techniques include part-of-speech (POS) tagging, speech recognition, machine translation, and sentiment analysis. POS tagging is a linguistic activity in NLP that clears out ambiguity in terms with numerous meanings and reveals a sentence's grammatical structure, while NLP models can help speech recognition systems understand the context of the spoken words better.
Early NLP systems relied on a rule-based approach, dictionary lookups, and statistical methods, which usually support basic decision-tree models and, eventually, machine learning-automated tasks while enhancing results. As the field of NLP evolved, it's now commonly built on deep learning models, a more powerful machine learning type. Large datasets and a significant amount of pre-processing capability are needed for DL models, which can analyze unlabeled raw data to train models.
The following are the most popular NLP pre-trained models:
Computer vision is a field of AI that uses machine learning and neural networks that empower computers to interpret visual data, like images and videos, and make recommendations. It uses sophisticated algorithms to process and understand visual information and mimics how human vision works. Computer vision can perform various tasks, including object detection, facial recognition, image segmentation, video analysis, autonomous navigation, and more.
Computer vision models run on algorithms trained on massive amounts of visual data or images in the cloud. These models recognize patterns in the visual data and use those patterns to determine the content of other images. A computer vision system divides it into pixels instead of looking at an entire image, like humans do. It uses RGB values of each pixel to look for important features in an image.
A computer vision model works by using a sensing device to capture an image and send it to an interpreting device for analysis via pattern recognition. The interpreting divide then matches the pattern in the image to its library of existing (or known) patterns to get specific information about the image. Key computer vision techniques include the following:
Generative AI models are robust AI platforms that produce various outputs based on large training datasets, neural networks, deep learning, and user prompts. These models use unsupervised or semi-supervised learning methods and are trained to recognize small-scale and overarching patterns or relationships within training datasets. Data used to train genAI models can come from various sources, including the Internet, books, stock images, online libraries, and more.
Different genAI model types can generate various outputs, including images, videos, audio, and synthetic data. These models allow you to produce new content or repurpose material, as a human would generate these outputs instead of a machine. Many generative AI models exist today, including text-to-text generators, text-to-image generators, image-to-image generators, and image-to-text generators. It's also possible for a model to fit into multiple categories, such as the latest development of ChatGPT and GPT-4, making it a transformer-based, large language, multimodal model.
The following are the most common types of generative AI models:
Generative AI models are highly scalable and accessible AI solutions for various business applications.
