What are you looking for?

It requires a lot of high quality labeled data, voice recordings annotated with their phonetic spellings, and natural language transcriptions aligned with the audio files. Some of the algorithms you learn in this book might help, but most of the recognition and generation algorithms are quite different. The word natural in natural language is used in the same sense that it is used in natural world. Natural, evolved things in the world about us are different from mechanical, artificial things designed and built by humans.

Being able to design and build software that can read and process language like what you’re reading here—language about building software that can process natural language… They aren’t intended to be translated into a finite set of mathematical operations, like programming languages are. We don’t use programming languages to tell each other about our day or to give directions to the grocery store.

You’ll learn how to automatically group natural language words together into groups of words with similar meanings without having to hand-craft synonym lists. Very quickly you’ll be able to build algorithms that can make decisions about natural language as well or better than you can (and certainly much faster). This may be the first time in your life that you have the perspective to fully appreciate the way that words reflect and empower your thinking.

Natural languages can’t be directly translated into a precise set of mathematical operations, but they do contain information and instructions that can be extracted. Those pieces of information and instruction can be stored, indexed, searched, natural language processing in action or immediately acted upon. One of those actions could be to generate a sequence of words in response to a statement. By the end of part 1, you’ll have the tools you need for many interesting NLP applications—from semantic search to chatbots.

About This Book

Because many firms have made ambitious bets on AI only to struggle to drive value into the core business, remain cautious to not be overzealous. This can be a good first step that your existing machine learning engineers — or even talented data scientists — can manage. So extracting information isn’t at all like building a programming language compiler (fortunately for you). The most promising techniques bypass the rigid rules of regular grammars (patterns) or formal languages.

Of course we authors used various search engines throughout the writing of this textbook. In some cases these search results included social posts and articles curated or written by bots, which in turn inspired many of the NLP explanations and applications in the following pages. He has over twenty years experience building autonomous systems and NLP pipelines for both large corporations and startups.

We also ignore speech generation or text to speech, converting text back into some human-sounding voice utterance. But you can still use what you learn to build a voice interface or virtual assistant like Siri or Alexa, because speech-to-text and text-to-speech libraries are freely available. Android and iOS mobile operating systems provide high quality speech recognition and generation APIs, and there are Python packages to accomplish similar functionality on a laptop or server.

Spam filters of the type you’ll build in chapters 2 through 4 are what saved the global email system from anarchy and stagnation. You’ll learn how to build a spam filter with better than 90% accuracy using 1990s era technology—calculating nothing more than the counts of words and some simple averages of those counts. Natural Language Processing in Action is a practical guide to processing and generating natural language text in the real world. A supportive community emerged through open, honest, prosocial communication over the internet using the language that came naturally to us. And we hope that when superintelligence does eventually emerge, it will be nudged, ever so slightly, by this prosocial ethos.

Definition   A natural language processing system is often referred to as a pipeline because it usually involves several stages of processing where natural language flows in one end and the processed output flows out the other. Nonetheless, this chapter shows you how a machine can process natural language. You might even think of this as a natural language interpreter, just like the Python interpreter. When the computer program you develop processes natural language, it will be able to act on those statements or even reply to them. But these actions and replies aren’t precisely defined, which leaves more discretion up to you, the developer of the natural language pipeline. You are about to embark on an exciting adventure in natural language processing.

While knowledge of object-oriented Python development may help you build better systems, it’s not required to use what you learn in this book. The development of NLP systems has built to a crescendo of information flow and computation through and among human brains. We can now type only a few characters into a search bar, and often retrieve the exact piece of information we need to complete whatever task we’re working on, like writing the software for a textbook on NLP. The top few autocomplete options are often so uncannily appropriate that we feel like we have a human assisting us with our search.

Smart search is another tool that is driven by NPL, and can be integrated to ecommerce search functions. This tool learns about customer intentions with every interaction, then offers related results. However, it has come a long way, and without it many things, such as large-scale efficient analysis, wouldn’t be possible. In chapter 3, we count those words and assemble them into vectors that represent the meaning of a document. You can use these vectors to represent the meaning of an entire document, whether it’s a 140-character tweet or a 500-page novel. The rich diversity of the drawings in Hacquet’s publications speaks vividly of the uniqueness and individuality of the eastern Alpine regions just 200 years ago.

• Customer service and customer success leaders can get real-time feedback and tips to better close a deal, handle objections, or empathize with unhappy customers in real time.
• If a customer has an objection the technology surfaces a step-by-step prompt to help reps overcome it.
• In this piece, we’ll go into more depth on what NLP is, take you through a number of natural language processing examples, and show you how you can apply these within your business.
• If you want to build a customized speech recognition or generation system, that undertaking is a whole book in itself; we leave that as an exercise for the reader.
• If you have talked to a customer before, Cyrano.AI has patented technology that analyzes previous conversations to create a profile of the customer.
• Obviously these machines were under the control of thinking and introspective humans, but when you realize that those humans are being influenced by the bots, the mind begins to boggle.

Right now tools like Elicit are just emerging, but they can already be useful in surprising ways. In fact, the previous suggestion was inspired by one of Elicit’s brainstorming tasks conditioned on my other three suggestions. The original suggestion itself wasn’t perfect, but it reminded me of some critical topics that I had overlooked, and I revised the article accordingly. In organizations, tasks like this can assist strategic thinking or scenario-planning exercises. Although there is tremendous potential for such applications, right now the results are still relatively crude, but they can already add value in their current state.

That’s great news for businesses since NLP can have a dramatic effect on how you run your day-to-day operations. It can speed up your processes, reduce monotonous tasks for your employees, and even improve relationships with your customers. The bottom line is that you need to encourage broad adoption of language-based AI tools throughout your business. It is difficult to anticipate just how these tools might be used at different levels of your organization, but the best way to get an understanding of this tech may be for you and other leaders in your firm to adopt it yourselves.
