An Introduction to Natural Language Processing NLP

While NLP and other forms of AI aren’t perfect, natural language processing can bring objectivity to data analysis, providing more accurate and consistent results. Now that we’ve learned about how natural language processing works, it’s important to understand what it can do for businesses. Let’s look at some of the most popular techniques used in natural language processing. Note how some of them are closely intertwined and only serve as subtasks for solving larger problems. In other words, word frequencies in different documents play a key role in extracting the latent topics. LSA tries to extract the dimensions using a machine learning algorithm called Singular Value Decomposition or SVD.

Semantics is a branch of linguistics, which aims to investigate the meaning of language. Semantics deals with the meaning of sentences and words as fundamentals in the world. The overall results of the study were that semantics is paramount in processing natural languages and aid in machine learning.

It is also sometimes difficult to distinguish homonymy from polysemy because the latter also deals with a pair of words that are written and pronounced in the same way. Word Sense Disambiguation [newline]Word Sense Disambiguation (WSD) involves interpreting the meaning of a word based on the context of its occurrence in a text. Thus, either the clusters are not linearly separable or there is a considerable amount of overlaps among them. The TSNE plot extracts a low dimensional representation of high dimensional data through a non-linear embedding method which tries to retain the local structure of the data. This means that most of the words are semantically linked to other words to express a theme.

As discussed earlier, semantic analysis is a vital component of any automated ticketing support. It understands the text within each ticket, filters it based on the context, and directs the tickets to the right person or department (IT help desk, legal or sales department, etc.). Maps are essential to Uber’s cab services of destination search, routing, and prediction of the estimated arrival time (ETA). All these services perform well when the app renders high-quality maps. Along with services, it also improves the overall experience of the riders and drivers. The semantic analysis uses two distinct techniques to obtain information from text or corpus of data.

The journey of NLP and semantic analysis is far from over, and we can expect an exciting future marked by innovation and breakthroughs. The semantic analysis will expand to cover low-resource languages and dialects, ensuring that NLP benefits are more inclusive and globally accessible. Much like any worthwhile tech creation, the initial stages of learning how to use the service and tweak it to suit your business needs will be challenging and difficult to adapt to.
