How deep learning complements natural language processing

Let’s begin with some numbers. Statista estimated that the Artificial Intelligence market leveraging Natural Language Processing would exceed an evaluation of $127 billion by 2028. This indicates the surging interest in NLP applications, attracting tech-tycoons willing to invest heavily in further enhancing this technology. This – in turn – attracts more young talents who can dedicate their career to developing NLP. However, before deploying NLP at mass, there still are challenges that need to be addressed by developers.

Key Takeaways On Natural Language Processing

·       Terms like Artificial Intelligence, Deep Learning, and Natural Language Processing are often interchangeably used. However, their operations, applications, and definitions are different in Computer Science.

·       Natural Language Processing is constantly evolving with enterprise solutions that can handle speech analysis, sentiment interpretation, and market intelligence – making it scalable and efficient in industrial applications.

·       The use of Natural Language Processing comes with its advantages – and disadvantages as well. While it's true that businesses can cut down on costs, there are technological challenges that hold back NLP even today.

One Quick Introduction To Natural Language Processing

In the Artificial Intelligence domain, Natural Language Processing or NLP is a fundamental application evolving rapidly with new methodologies and toolkits. If you hold a Bachelors's or Masters's degree in Computer Science or Information Technology, you already have a fair bit of knowledge of how it works. In summary, “natural language” refers to how humans interact with one another – primarily through speech, expressions, and gestures. Therefore, NLP relates to the capability of computer systems to interpret natural language in an actionable manner.

The Current Limitations Of NLP

Over the past decade, NLP has made pretty serious progress in language interpretation. However, there are still a few major gaps – notably with generating description or data accuracy. Sometimes, performance is less stable, and humans need to double-check it. Other challenges include filtering any noise from the data it’s trained on. Interpretations are likely to be less efficient if the fed data is corrupted. Therefore, unless generative models become more flexible and human-like than retrieval models, Natural Language Processing can’t be deployed in mass applications.

The Fundamentals Of Retrieval And Generative Models

Retrieval Model In NLP: In the retrieval model, the algorithm typically leverages canned responses and heuristics for selecting probable responses according to the input text. However, retrieval models are inefficient with grammatical errors, and therefore, they cannot interpret specific conversational texts with no predefined responses.

Generative Model In NLP: Generative models – on the other hand – can interpret entirely new responses and can also dynamically address unforeseen cases. They are smart, efficient, and complex. However, the generative model has one major caveat – it requires vast pools of training data and uses complicated techniques like machine translation.

The Role Of Deep Learning In Natural Language Processing

That is where Deep Learning comes into action! Before Deep Learning, NLP relied on the Bag of Words models like Naïve Bayes, SVM, and Logistic Regression for classifying text inputs. The main model drawback was their disregard for context in conversational word orders. This landscape soon changed with Recurrent Neural Networks, designed to process sequential data and capture short-term dependencies. Additionally, Deep Learning enables better sentiment analysis, making it accurate at interpreting feelings.

This model benefits from a feed-forward neural network as a classifier and adjusts its parameters in the dependency syntax analyzer to achieve better results. What’s unique about the feed-forwarding is that the model can memorize the analysis state and history, which enables it to capture and utilize more historical information. In addition, it can model the entire sentence's analysis process and improve the independent state's modeling. Therefore, with further error analysis, analysts can study dependency syntax analysis based on the neural network.

What Does The Future Of NLP Hold?

Although significant advancements have been made in the generative model, the current NLP systems still function on the elementary nature of retrieval-based models. Real conversations – aren’t scripted, are free-form, and unstructured – have a finite set of responses. Therefore, retrieval models are vastly more appropriate for handling natural language.
