What is Natural Language Processing? An Introduction to NLP

Current approaches to natural language processing are based on deep learning, a type of AI that examines and uses patterns in data to improve a program’s understanding. It is faster in most cases, but it only has a single implementation for each NLP component. Also, it represents everything as an object rather than a string, which simplifies the interface for building applications. This also helps it integrate with many other frameworks and data science tools, so you can do more once you have a better understanding of your text data. It does have a simple interface with a simplified set of choices and great documentation, as well as multiple neural models for various components of language processing and analysis. Overall, this is a great tool for new applications that need to be performant in production and don’t require a specific algorithm.

TextBlob is a Python library that works as an extension of NLTK, allowing you to perform the same NLP tasks in a much more intuitive and user-friendly interface. Its learning curve is more simple than with other open-source libraries, so it’s an excellent choice for beginners, who want to tackle NLP tasks like sentiment analysis, text classification, part-of-speech tagging, and more. NLP techniques open tons of opportunities for human-machine interactions that we’ve been exploring for decades. Script-based systems capable of “fooling” people into thinking they were talking to a real person have existed since the 70s. But today’s programs, armed with machine learning and deep learning algorithms, go beyond picking the right line in reply and help with many text and speech processing problems.

It helps us to apply statistical models and analysis on human language to gain inference and insight into human behavior, communication, and speech patterns. CoreNLP is a production-ready solution built and maintained by Stanford group. This library is optimized for speed and has functions like Part-of-Speech tagging, pattern learning parsing, titled entity recognition, and much, much more.

Google Translate is such a tool, a well-known online language translation service. Previously Google Translate used a Phrase-Based Machine Translation, which scrutinized a passage for similar phrases between dissimilar languages. Presently, Google Translate uses Google Neural Machine Translation instead, which uses machine learning and natural language processing algorithms to search for language patterns. In this article, we’ll try multiple packages to enhance our text analysis.

It was proposed by Pang and Lee and subsequently extended by Socher et al. . The annotation scheme has inspired a new dataset for sentiment analysis, called CMU-MOSI, where sentiment is studied in a multimodal setup (Zadeh et al., 2013). To avoid the gradient vanishing problem, LSTM units have also been applied to tree structures (Tai et al., 2015).

Introduction to Natural Language Processing

Topic modeling can quickly give us an insight into the content of the text. Unlike extracting keywords from the text, topic modeling is a much more advanced tool that can be tweaked to our needs. Be aware though, the model is using stopwords in assessing which words are important within the sentences. If we were to feed this model with a text cleaned of stopwords, we wouldn’t get any results. Machine learning and Natural Language Processing are two very broad terms that can cover the area of text analysis and processing. We’re not going to try to set a fixed line between these two terms, we’ll leave that to the philosophers.

For example, even grammar rules are adapted for the system and only a linguist knows all the nuances they should include. For example, grammar already consists of a set of rules, the same as spelling. A system armed with a dictionary will do its job well, though it won’t be able to recommend a better choice of words and phrasing. This is not an exhaustive list of all NLP use cases by far, but it paints a clear picture of its diverse applications.

Natural language processing shifted from a linguist-based approach to an engineer-based approach, drawing on a wider variety of scientific disciplines instead of delving into linguistics. Natural language processing is the ability of a computer program to understand human language as it is spoken and written — referred to as natural language. CogCompNLP, developed by the University of Illinois, also has a Python library with similar functionality. It can be used to process text, either locally or on remote systems, which can remove a tremendous burden from your local device. It provides processing functions such as tokenization, part-of-speech tagging, chunking, named-entity tagging, lemmatization, dependency, and constituency parsing, and semantic role labeling. Overall, this is a great tool for research, and it has a lot of components that you can explore.

By capturing relationships between words, the models have increased accuracy and better predictions. You might have heard of GPT-3 — a state-of-the-art language model that can produce eerily natural text. It predicts the next word in a sentence considering all the previous words. Not all language models are as impressive as this one, since it’s been trained on hundreds of billions of samples. But the same principle of calculating the probability of word sequences can create language models that can perform impressive results in mimicking human speech.

What is Natural Language Processing (NLP) Software?

Yu et al. proposed to bypass this problem by modeling the generator as a stochastic policy. The reward signal came from the GAN discriminator judged on a complete sequence and was passed back to the intermediate state-action steps using a Monte Carlo search. Reinforcement learning is a method of training an agent to perform discrete actions before obtaining a reward. In NLP, tasks concerning language generation can sometimes be cast as reinforcement learning problems. For example, the task of text summarization can be cast as a sequence-to-sequence learning problem, where the input is the original text and the output is the condensed version.

Following this approach, Poria et al. employed a multi-level deep CNN to tag each word in a sentence as a possible aspect or non-aspect. Coupled with a set of linguistic patterns, their ensemble classifier managed to perform well in aspect detection. Traditional word embedding methods such as Word2Vec and Glove consider all the sentences where a word is present in order to create a global vector representation of that word. However, a word can have completely different senses or meanings in the context.

This article is about natural language processing done by computers. For the natural language processing done by the human brain, see Language processing in the brain. To improve their manufacturing pipeline, NLP/ ML systems can analyze volumes of shipment documentation and give manufacturers deeper insight into their supply chain areas that require attention. Using this data, they can perform upgrades to certain steps within the supply chain process or make logistical modifications to optimize efficiencies. Using emotive NLP/ ML analysis, financial institutions can analyze larger amounts of meaningful market research and data, thereby ultimately leveraging real-time market insight to make informed investment decisions.

Machine learning-based NLP — the basic way of doing NLP

NLP APIs can be an unpredictable black box—you can’t be sure why the system returned a certain prediction, and you can’t troubleshoot or adjust the system parameters. You can see the source code, modify the components, and understand why your models behave the way they do. It is open-source, extensible, and can be run as a simple web service.

Find reviews from organizations similar to yours so that you get a real picture of how the solution works. If you can find contact information for particularly interesting reviews, you may be able to get more information directly from the source. Consider each person on your team and how they will interact with the software. Decide if the system is largely internal, e.g., for coordinating financial agreements, or external, such as providing customer service.

Then, pipe the results into the Sentiment Analysis algorithm, which will assign a sentiment rating from 0-4 for each string. Generate keyword topic tags from a document using LDA, which determines the most relevant words from a document. This algorithm is at the heart of the Auto-Tag and Auto-Tag URL microservices.

Using Machine Learning and Natural Language Processing Tools for Text Analysis

In particular, the authors proposed two types of Chinese radical-based hierarchical embeddings, which incorporate not only semantics at radical and character levels, but also sentiment information. Bojanowski et al. also tried to improve the representation of words by using character-level information in morphologically-rich languages. They approached the skip-gram method by representing words as bag-of-characters n-grams. Their work thus had the effectiveness of the skip-gram model along with addressing some persistent issues of word embeddings. The method was also fast, which allowed training models on large corpora quickly.
