Top NLP Algorithms to Try and Explore in this 2021 for Sure – Analytics Insight

Machine learning for natural language processing or NLP and text analytics involves using machine learning algorithms and AI to understand the meaning of text documents. The role of machine learning and AI in NLP and text analytics is to accelerate the underlying and NLP features that turn this unstructured text into usable data and insights. Let’s see the top NLP algorithms to explore in 2021.

What is Natural Language Processing?

NLP stands for Natural Language Processing which is a subfield of Artificial Intelligence research. It is focused on the development of models and protocols that will help you in interacting with computers based on natural language.

Top NLP algorithms to explore

Lemmatization and Stemming

Lemmatization and Stemming can help you in creating an NLP of the tasks. These techniques can be used according to the needs. Lemmatization and Stemming are two very different techniques and both of them can be completed using various other ways, but the ultimate result is the same for both: a smaller search space for the problem we are facing.

Keyword Extraction

One of the vital tasks of NLP is keywords extraction which is extracting an important set of words and phrases from a collection of texts. This can help in summarizing and helping to organize, search, store, and retrieve contacts in a relevant and well-organized manner. Some of the most popular keyword extraction algorithms are TextRank, TF-IDF, and RAKE.

Topic Modelling

Topic Modelling is an NLP activity where we strive to identify ‘abstract subjects’ that can define a text set. Latent Dirichlet Allocation is one of the most common NLP algorithms for Topic Modelling. You do this by allocating a text to a random subject in your dataset and then you go through the sample many times.

Knowledge Graphs

It is a method of storing information in utilizing triples by knowledge graphs-a collection of three subjects such as a subject, predicate, and an entity. As nowadays knowledge graphs have become common, most businesses are using them. Building a knowledge graph needs a wide range of NLP techniques to be more detailed and effective.

Named Entity Recognition

Name Entity Recognition is another technique for the processing of NLP space. It is responsible for defining and assigning people in an unstructured text to a list of predefined categories such as groups, people, money, and times. Named Entity Recognition consists of two sub-steps. These steps include Named Entity Identification and Named Entity Classification.

Words Cloud

A word cloud represents a technique for visualizing data. In this method, words from a document are shown in a table with the most vital words being written in the larger fronts and less important ones in smaller fonts.

Machine Translation

Machine Translation consists of both linguistic study and the development of languages. We can use a concurrency corpus which is a set of documents for this method. This method skips hundreds of crucial data that involves a lot of human function engineering. And also has a lot of separate and distinct machine learning concerns.

Sentiment Analysis

Sentiment analysis is the most common method used by NLP algorithms. it can be performed using both supervised and unsupervised methods. A training corpus with sentiment labels is required, on which a model is trained and then used to define the sentiment. Naive Bayes isn’t the only platform out there-it can also use multiple machine learning methods such as random forest or gradient boosting.
