AI and understanding semantics, next stage in evolution of NLP is close

Currently in development is the The VerbNet Class Disambiguator, which uses a supervised machine learning approach to classify verb tokens with VerbNet classes. It has been trained and tested with 30 verbs to date. With this initial sample, it achieves 90% accuracy, which represents a 61% error reduction over the most-frequent-class baseline. Work is underway to increase its coverage to all the multiclass verbs in the Semlink corpus.

• While this decade has seen large advantages in understanding voices Silicon Valley knows (mainly, American male), databases are only now being expanded to understand a wider variety of spoken language.
• The resultant models can then use those patterns to construct complete sentences or paragraphs, and power things like autocomplete or other predictive text systems.
• Active learning is one type of selective sampling, but in many situations it is not practical (e.g. a multi-annotator, double-annotation environment).
• But in the longer term, he believes, they all have limits.

This is somewhat proven by Open AI’s GPT-2 model, which shows that using the same sentence encoding model designs with a large amount of data, produces models that already understand high-level concepts across many sentences. For example, GPT-2 understands enough to write entire news articles with astonishing coherence. “There is a clear pattern of hierarchy emerging in the progression of this technology.

AI and understanding semantics — the next stage in the evolution of NLP is close

These algorithms can only handle very simple sentences and therefore fail to capture nuance. Because they require a lot of context-specific training, they’re also not flexible. The models they produce don’t actually understand the sentences they construct. At the end of the day, they’re writing prose using word associations. “As these costs decline from advancements in AI hardware, we will see ourselves getting closer to models that understand larger collections of text.

That’s essentially why NLP and Search continue to attract significant research dollars. Going forward, innovative platforms will be those that are able to process language better and provide friendlier interaction mechanisms beyond a keyboard. Possibilities are immense be it intelligent answering machines, machine-to-machine communications or machines that can take action on behalf of humans. Internet itself will transform from connected pages to connected knowledge if you go by the vision of Tim Berners-Lee – the father of internet.

Computational Language and Education Research CLEAR

The advances that brought cloud computing also helped natural language work. The processing power of clusters of computer and processors meant that more complex analysis could be done much faster. That brought artificial neural networks (ANN) to the front of the machine learning world.

Syntax is the structure of language, and it clearly aids in defining semantics, or the meaning of the communications. To understand how computers are rapidly improving, it’s important to look at how natural language is different from what computers have historically processed. Algorithms based on frame semantics use a set of rules or lots of labeled training data to learn to deconstruct sentences.

In addition, changes in volume and accent can have a strong effect on understanding. While this decade has seen large advantages in understanding voices Silicon Valley knows (mainly, American male), databases are only now being expanded to understand a wider variety of spoken language. The expanding number of rules slowed systems and didn’t get to the high level of accuracy required in conversation. “The idea is that you can take a sentence, encode it into a sentence (or thought) vector and then find similar sentence vectors.

Closing that gap would probably require a new way of thinking, he adds, as well as much more time. Markets&Markets – a leading premium markets researcher anticipates NLP market to grow to $13.4 billion by 2020 at a CAGR of 18.4%. Clearly, this presents solid opportunity for a software developer who is looking forward to building expertise in areas that will shape the future and will continue to command premium. ANNs are also helping on the language generation front.

Organizations across verticals feel the pain from this gap and this presents huge opportunity for NLP/Search practitioners. Commoditization of data scienceAnother key development has been that the tools for predictive and prescriptive analytics have become more consumable. This combined with need for monetizing unstructured data has given huge surge to text analytics as is evidenced by the focus text mining, information retrieval topics receive in major conferences these days. Robotic process automation, optical character recognition, and natural language processing, or RPA, OCR and NLP, are some examples of newer technologies that positively affect businesses.
