Natural Language Understanding: Measuring the Semantic Similarity between Sentences Undergraduate Research Opportunities

What is Natural Language Processing NLP?

Basic NLP tasks include tokenisation and parsing, lemmatisation/stemming, part-of-speech tagging, language detection and identification of semantic relationships. If you ever diagrammed sentences in grade school, you’ve done these tasks manually before. The Real-Time Agent Assist tool aids in note-taking and data entry and uses information from ongoing conversations to do things like activating knowledge retrieval and behaviour guidance in real-time. The further into the future we go, the more prevalent automated encounters will be in the customer journey.

This fascinating and growing area of computer science has the potential to change the face of many industries and sectors and you could be at the forefront. Simple emotion detection systems use lexicons – lists of words and the emotions they convey from positive to negative. More advanced systems use complex machine learning algorithms for accuracy. This is because lexicons may class a word like “killing” as negative and so wouldn’t recognise the positive connotations from a phrase like, “you guys are killing it”. Word sense disambiguation (WSD) is used in computational linguistics to ascertain which sense of a word is being used in a sentence.

This can help companies to remain competitive in their industry and focus on what they do best. However, the geographical location of the user could https://www.metadialog.com/ be an optional input. If the user wants to say they are from the UK, this can be used as a filter to only show the batteries with a three pin plug.

How does natural language understanding NLU work in AI?

Natural language understanding (NLU) is a branch of artificial intelligence (AI) that uses computer software to understand input in the form of sentences using text or speech. NLU enables human-computer interaction by analyzing language versus just words.

There is a 2017 paper on the categorisation of queries; navigation, transactional & inspirational but since there has also been further categorised queries, such as spoken and action queries. Motorway and travelling can be problematic, especially getting results for your destination, rather than the location you’ve just nlu algorithms passed. There’s time-sensitive intent too, example of ‘dresses’ where users wanted wedding dresses, rather than general dresses. The reason was due to the search being made during the royal wedding and people wanted to see Megan Markle’s wedding dress. So, it’s only increasing in complexity rather than becoming easier.


For this, they identify each of its products according to the distinct characteristics of a human being. It aims at humanizing its different algorithmic products as much as they can. To do this, the Google engineering team has borrowed concepts from a lot of sources.

Health literacy refers to patients’ ability to obtain, understand and use health information to make informed healthcare decisions. While natural language processing cannot replace medical professionals, NLP can be used to allow patients to interact with healthcare chatbots. You can use this information to segment your audience and create buyer personas (client profiles) based on how they interact with your content/brand. Buyer personas further enable you to tailor your content and marketing strategy to their specific needs and wants. This important trio is so great because it’s the oldest algorithm models that the company has had.

VUI: the dawn of voice

During this era, the company’s need to have control over the quality of content played a big role. Page Rank, the first and oldest of all Google’s algorithms, had as its goal the creation of data sets based on the quality of their information. So, to mathematically measure the quality of a website’s content, the algorithm uses the concept of “domain authority”. Natural language processing is a rapidly evolving field with many challenges and opportunities. Labelled data is data with labels that indicate what the data is about. Without labelled data, it is difficult to train machines to accurately understand natural language.


An automated system should approach the customer with politeness and familiarity with their issues, especially if the caller is a repeat one. It’s a customer service best practice, after all, to be able to get to the root of their issue quickly, and showing that extra knowledge nlu algorithms and care is the cherry on top. Omnichannel bots can be extremely good at what they do if they are well fed with data. The more linguistic information an NLU-based solution onboards, the better a job it can do in assisting customers, such as in routing calls more effectively.

Google’s recently published paper on its gaming program AlphaGo Zero embodies even stronger AI capabilities. The program was built without reliance on any human gaming data, and turned out to be stronger than its previous versions. The launch of AlphaGo Zero marks a brighter future for AI as it could revolutionise how AI software is built. In the future, data is likely to be less important in AI software development. Instead, AI software developers will focus on finding applications with a high potential for repetitions.

  • Machine validation is indispensable as it helps identify potential biases, limitations, and vulnerabilities that could adversely impact AI systems.
  • Remember that it must go along to the parameters of Google’s algorithms.
  • Natural language generation involves the use of algorithms to generate natural language text from structured data.
  • On the other hand, the influence of the Knowledge Graph function is something to always keep in mind.

Without being able to infer intent accurately, the user won’t get the response they’re looking for. Without a strong relational model, the resulting response isn’t likely to be what the user intends to find. The key aim of any Natural Language Understanding-based tool is to respond appropriately to the input in a way that the user will understand.

Which language is better for NLP?

Although languages such as Java and R are used for natural language processing, Python is favored, thanks to its numerous libraries, simple syntax, and its ability to easily integrate with other programming languages.
