Natural Language Processing NLP cmpt310summer2019 documentation

Now that algorithms can provide useful assistance and demonstrate basic competency, AI scientists are concentrating on improving understanding and adding more ability to tackle sentences with greater complexity. Some of this insight comes from creating more complex collections of rules and subrules to better capture human grammar and diction. Lately, though, the emphasis is on using machine learning algorithms on large datasets to capture more statistical details on how words might be used.

Some tools are built to translate spoken or printed words into digital form, and others focus on finding some understanding of the digitized text. One cloud APIs, for instance, will perform optical character recognition while another will convert speech to text. Some, like the basic natural language API, are general tools with plenty of room for experimentation while others are narrowly focused on common tasks like form processing or medical knowledge.

While humans may instinctively understand that different words are spoken at home, at work, at a school, at a store or in a religious building, none of these differences are apparent to a computer algorithm. The technology at the time also meant that the focus of language was on written language. In addition, it was easier to create syntactically correct output than to read the way we write, so the focus was on the complexity of NLP while NLG was often kept very simple. Another area where NLP can come in handy is business analytics, allowing users to look for information using common phrases rather than having to adjust their wording to what the search engine or business intelligence tool will understand. In a way, they are a more capable technology than the NLP multi-query example above.

One criterion for the test involved deciding whether the computer could interpret and generate natural language. Nori Health intends to help sick people manage chronic conditions with chatbots trained to counsel them to behave in the best way to mitigate the disease. They’re beginning with “digital therapies” for inflammatory conditions like Crohn’s disease and colitis.

Quick search

Some AI scientists have analyzed some large blocks of text that are easy to find on the internet to create elaborate statistical models that can understand how context shifts meanings. A book on farming, for instance, would be much more likely to use “flies” as a noun, while a text on airplanes would likely use it as a verb. For example, an information extraction system might search a text to final allemail addresses, or all company names, or all products and their prices, etc. At the lowest level, it’s just a sort of user interface that parses and interprets text (or voice). “The output of NLP can be used for subsequent processing or search,” the company explains. While the technology tools matter, Agrawal emphasizes that humans should also play a role in determining the result of an NLP use case.

I’ve seen cases where these queries are iterative, where the user actually conducts a dialogue. I’ve heard the term so frequently, I thought I’d try to create a sort of taxonomy of the different types and functions of NLP. The broadest definition of NLP is a method of communicating with intelligent systems using natural language. “The top use cases for NLP today — improving the customer experience and helping employees reach new levels of productivity — are critical priorities for nearly every business,” says Dakshi Agrawal, an IBM fellow and CTO for AI at IBM. Already, innovators are making progress on NLP-based tools that could eventually take the place of people. Consider the underappreciated chief of staff or the administrative assistant who schedules and takes notes during meetings and generally keeps the organizational trains running on time.

Management AI: Natural Language Processing (NLP) and Natural Language Generation (NLG)

NLP is an increasingly common branch of AI, found in everything from smartphones to home kitchens, and involves the ability of computers to understand spoken language and text. The goal is now to improve reading comprehension, word sense disambiguation and inference. Beginning to display what humans call “common sense” is improving as the models capture more basic details about the world. AI scientists hope that bigger datasets culled from digitized books, articles and comments can yield more in-depth insights. For instance, Microsoft and Nvidia recently announced that they created Megatron-Turing NLG 530B, an immense natural language model that has 530 billion parameters arranged in 105 layers. One application that is getting a lot of notice in the BI/Visualization space is Narrative Science.

On the natural language processing side, that has allowed systems to far more rapidly analyze large amounts of text data. That has led to advances in internet search capacity, customer service sentiment analysis, and in multiple other areas. There’s a large volume of information in any major retailer’s technology infrastructure. Expecting to get hundreds of merchandising agents to learn how to use a complex business intelligence (BI) interface or all become experts at pivot tables is a non-starter. The software becomes, as referred to in the on-premises days, as shelf-ware – software paid for but not used. Google offers an elaborate suite of APIs for decoding websites, spoken words and printed documents.

• The Document AI tool, for instance, is available in versions customized for the banking industry or the procurement team.
• Personalization is also an important use case for many companies, with its use seen as a major element of understanding customer sentiment and offering services tailored to their needs.
• Shield wants to support managers that must police the text inside their office spaces.
• After deduplication and cleaning, they built a training set with 270 billion tokens made up of words and phrases.
• At a high level, natural language processing describes a computer’s ability to process and comprehend language, whether in written, spoken or digital form.

AI Strategies: What Is Natural Language Processing and How Can It Help Businesses?

But if it genuinely has semantic understanding, remember, the simplest things to say are often the most difficult for a machine to understand (“summarize that”). NLP apps like sentiment analysis, chatbots, etc. stand on their own as actual applications of NLP technology. But they should still be put to the test before NLP claims are made – not all bots are created equal. When you get down to bits and bytes, these smarter NLP’s use actual AI techniques in the form of Recurrent Neural Networks and Attention Neural Networks, which allow for temporal (time) dynamic behavior.

IBM approaches AI through a four-step system it calls the AI Ladder, which involves collecting, organizing and analyzing data, then spreading the lessons of that data throughout the organization. For example, early optical character recognition systems relied on specialized fonts that computers could detect.

For the next 50 years, linguists developed NLP using painstaking trial-and-error rules.
