AI Strategies: What Is Natural Language Processing NLP?

Customer support implementations also have yet to tap into the full benefits of machine learning and natural language processing to improve the customer experience at a reduced cost. Both large and small businesses can do so by implementing next-generation CX tools that leverage ML and NLP-based conversational interfaces. In recent decades, machine learning algorithms have been at the center of NLP and NLU. Machine learning models are knowledge-lean systems that try to deal with the context problem through statistical relations.

Then, an NLI should be designed to directly combat those issues and provide end-users with an optimized and actionable experience. Once the system is implemented, you should continuously and iteratively refine your UI/UX. You should note, though, that while the capabilities of NLIs are immensely beneficial, these models still struggle with handling ambiguity, understanding context and accurately responding in all cases. The technology will have to continue to evolve in order to meet current demand.

NLP vs. NLU and NLG: What’s the Difference?

In fact, the latter represents a type of supervised machine learning that connects to NLP. Dictation and language translation software began to mature in the 1990s. However, early systems required training, they were slow, cumbersome to use and prone to errors. It wasn’t until the introduction of supervised and unsupervised machine learning in the early 2000s, and then the introduction of neural nets around 2010, that the field began to advance in a significant way. In many ways, the models and human language are beginning to co-evolve and even converge. As humans use more natural language products, they begin to intuitively predict what the AI may or may not understand and choose the best words.

Systems that can understand and communicate in more natural language can speed the process of analysis and decision making. Words and images both have a place in the business analytics environment, so expect to see natural language tools penetrate much further into the market in the next two years. Another potential use case is speech-to-speech translation, which might be useful for dubbing movies. Most AI dubbing systems work by translating the text of a movie’s script in a roundabout way. First, the audio is transcribed into text, then translated, then finally converted back into audio. It’s extremely complicated and completely removes the expressivity of oral language as it misses out on idiomatic expressions unique to oral language.

Natural language processing can take on a variety of forms, but all are generally driven by two subsets of NLP that have similar names, sometimes used interchangeably. NLP also can help analyze large databases to gather a deeper level of intelligence for making big decisions, a use case that carries lots of potential for scaling up. IBM Watson currently is being used to help manage an AI-driven stock index that evaluates potential investments based on in-depth analysis of data gathered on the largest publicly traded corporations. 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.

NLP Business Use Cases

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. In addition, Meta said it’s now able to model spontaneous real-time chit-chat between two AI agents in a highly realistic way.

In Linguistics for the Age of AI, McShane and Nirenburg argue that replicating the brain would not serve the explainability goal of AI. “Agents operating in human-agent teams need to understand inputs to the degree required to determine which goals, plans, and actions they should pursue as a result of NLU,” they write. While the technology tools matter, Agrawal emphasizes that humans should also play a role in determining the result of an NLP use case.

NLP and Why It Matters

An AI agent can conduct an entire task – starting an action and completing it. Human language is complex and it can be an enigma — even for humans. Investing in NLP can skyrocket the ability of a business to effectively and seamlessly engage with customers globally, a particularly critical offering as our world becomes increasingly digital. Each NLP system uses slightly different techniques, but on the whole, they’re fairly similar. The systems try to break each word down into its part of speech (noun, verb, etc.). I might not touch on every technical definition, but what follows is the easiest way to understand how natural language processing works.

Back in those days the computers weren’t being jerks, they simply didn’t have the benefit of deep learning networks to drive their natural language processing. Things have changed a lot since 2010 – and even more since the ideas behind virtual assistants like Siri were first developed in the 1940s. Natural language processing is a lucrative commodity yet has one of the largest environmental impacts out of all the other fields in the artificial intelligence realm.

• In such cases, they interact with their human counterparts (or intelligent agents in their environment and other available resources) to resolve ambiguities.
• For individual AI agents and for systems, people intervene only to take care of problems as they crop up and to ensure oversight.
• And nowhere is this trend more evident than in natural language processing, one of the most challenging areas of AI.
• These systems can reduce or eliminate the need for manual human involvement.

The ability for humans to interact with machines on their own terms simplifies many tasks. There’s no question that natural language processing will play a prominent role in future business and personal interactions. Personal assistants, chatbots and other tools will continue to advance. This will likely translate into systems that understand more complex language patterns and deliver automated but accurate technical support or instructions for assembling or repairing a product.

This is why various experiments have shown that even the most sophisticated language models fail to address simple questions about how the world works. Knowledge-lean systems have gained popularity mainly because of vast compute resources and large datasets being available to train machine learning systems. With public databases such as Wikipedia, scientists have been able to gather huge datasets and train their machine learning models for various tasks such as translation, text generation, and question answering.

In the earlier decades of AI, scientists used knowledge-based systems to define the role of each word in a sentence and to extract context and meaning. Knowledge-based systems rely on a large number of features about language, the situation, and the world. This information can come from different sources and must be computed in different ways. In many ways, the difference between NLU and natural language generation (NLG) is the difference between the production of language and comprehension. 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. For IT teams, one good use case for natural language processing is document classification.
