Data Science at DIT: harnessing the potential of Natural Language Processing

Natural language processing startup NeuralSpace receives £1 2 million investment

natural language processing examples

A more general version of the NLP pipeline starts with speech processing, morphological analysis, syntactical analysis, semantic analysis, applying pragmatics, finally resulting in a meaning. Remember, the journey in NLP is an ongoing process of learning and discovery. Stay curious, keep exploring, and leverage the power of NLP to build remarkable applications that shape the future of technology.

Since machines have better computing power than humans, they can process text data and analyze them more efficiently. Government agencies are increasingly using NLP to process and analyze vast amounts of unstructured data. NLP is used to improve citizen services, increase efficiency, and enhance national security.

Intent classification

By using NLG techniques to respond quickly and intelligently to your customers, you reduce the time they spend waiting for a response, reduce your cost to serve and help them to feel more connected and heard. Don’t leave them waiting, and don’t miss out on the masses of customer data available for insights. Natural Language Generation systems can be used to generate text across natural language processing examples all kinds of business applications. However, as with any system, it’s best to use it in a targeted way to ensure you’re increasing your efficiency and generating ROI. An extractive approach takes a large body of text, pulls out sentences that are most representative of key points, and combines them in a grammatically accurate way to generate a summary of the larger text.

How is NLP used in hospitals?

NLP solutions can also analyze clinical documents and support physicians in real-time decision making. For instance, after analyzing doctor notes, the system can predict hospital bed demands, which gives hospital staff time to prepare and accommodate incoming patients.

LSTMs circumvent this problem by letting go of the irrelevant context and only remembering the part of the context that is needed to solve the task at hand. This relieves the load of remembering very long context in one vector representation. Gated recurrent units (GRUs) are another variant of RNNs that are used mostly in language generation. (The article written by Christopher Olah [23] covers the family of RNN models in great detail.) Figure 1-14 illustrates the architecture of a single LSTM cell. We’ll discuss specific uses of LSTMs in various NLP applications in Chapters 4, 5, 6, and 9. Naive Bayes is a classic algorithm for classification tasks [16] that mainly relies on Bayes’ theorem (as is evident from the name).

Automatic speech recognition (ASR)

We can filter out some filters – determiners have a low discriminating ability, similarly with the majority of verbs. If a system does not perform better than the MFS, then there is no practical reason to use that system. The MFS heuristic is hard to beat because senses follow a log distribution – a target word appears very frequently with its MFS, and very rarely with other senses. The distributional hypothesis can be modelled by creating feature vectors, and then comparing these feature vectors to determine if words are similar in meaning, or which meaning a word has. In the English WordNet, nouns are organised as topical hierarchies, verbs as entailment relations, and adjectives and adverbs as multi-dimensional clusters. For hyponym/hypernym relations, synsets are organised into taxonomic relations.

  • The style in which people talk and write (sometimes referred to as ‘tone of voice’) is unique to individuals, and constantly evolving to reflect popular usage.
  • On the other hand, lemmatization considers a word’s morphology (how a word is structured) and its meaningful context.
  • Using this “bag-of-words” model, we then need to assign to the context the most probable sense, by measuring the similarity between the context vector and the sense vectors.
  • The standard book for NLP learners is “Speech and Language Processing” by Professor Dan Jurfasky and James Martin.
