Understanding Semantic Analysis NLP

How Semantic Analysis Impacts Natural Language Processing

semantics analysis

The automated process of identifying in which sense is a word used according to its context. You understand that a customer is frustrated because a customer service agent is taking too long to respond. Thus, the ability of a machine to overcome the ambiguity involved in identifying the meaning of a word based on its usage and context is called Word Sense Disambiguation. At the end of most chapters, there is a list of further readings and discussion or homework exercises. These activities are helpful to students by reinforcing and verifying understanding. As an introductory text, this book provides a broad range of topics and includes an extensive range of terminology.

This process is experimental and the keywords may be updated as the learning algorithm improves. In the early days of semantic analytics, obtaining a large enough reliable knowledge bases was difficult. In 2006, Strube & Ponzetto demonstrated that Wikipedia could be used in semantic analytic calculations.[2] The usage of a large knowledge base like Wikipedia allows for an increase in both the accuracy and applicability of semantic analytics. For Example, you could analyze the keywords in a bunch of tweets that have been categorized as “negative” and detect which words or topics are mentioned most often.

Semantic analysis (machine learning)

This practice, known as “social listening,” involves gauging user satisfaction or dissatisfaction through social media channels. Search engines can provide more relevant results by understanding user queries better, considering the context and meaning rather than just keywords. However, machines first need to be trained to make sense of human language and understand the context in which words are used; otherwise, they might misinterpret the word “joke” as positive. On the one hand, the third and the fourth characteristics take into account the referential, extensional structure of a category.

  • For one thing, nonrigidity shows up in the fact that there is no single necessary and sufficient definition for a prototypical concept.
  • As discussed in previous articles, NLP cannot decipher ambiguous words, which are words that can have more than one meaning in different contexts.
  • Four characteristics, then, are frequently mentioned in the linguistic literature as typical of prototypicality.
  • Semantic analysis helps in processing customer queries and understanding their meaning, thereby allowing an organization to understand the customer’s inclination.

In semantic analysis with machine learning, computers use word sense disambiguation to determine which meaning is correct in the given context. A summary of the contribution of the major theoretical approaches is given in Table 2. Semantic analysis can also benefit SEO (search engine optimisation) by helping to decode the content of a users’ Google searches and to be able to offer optimised and correctly referenced content. The goal is to boost traffic, all while improving the relevance of results for the user. As such, semantic analysis helps position the content of a website based on a number of specific keywords (with expressions like “long tail” keywords) in order to multiply the available entry points to a certain page. For us humans, there is nothing more simple than recognising the meaning of a sentence based on the punctuation or intonation used.


This technique is used separately or can be used along with one of the above methods to gain more valuable insights. Semantic Analysis is a topic of NLP which is explained on the GeeksforGeeks blog. The entities involved in this text, along with their relationships, are shown below. Semantic Scholar is a free, AI-powered semantics analysis research tool for scientific literature, based at the Allen Institute for AI. Prototypical categories exhibit degrees of category membership; not every member is equally representative for a category. Prototypical categories cannot be defined by means of a single set of criterial (necessary and sufficient) attributes.
