Understanding Semantic Analysis NLP

But before getting into the concept and approaches related to meaning representation, we need to understand the building blocks of semantic system. For example, analyze the sentence “Ram is great.” In this sentence, the speaker is talking either about Lord Ram or about a person whose name is Ram. That is why the job, to get the proper meaning of the sentence, of semantic analyzer is important. Information extraction, retrieval, and search are areas where lexical semantic analysis finds its strength. Semantic analysis tech is highly beneficial for the customer service department of any company. Moreover, it is also helpful to customers as the technology enhances the overall customer experience at different levels.

As you can see, this approach does not take into account the meaning or order of the words appearing in the text. Moreover, in the step of creating classification models, you have to specify the vocabulary that will occur in the text. — Additionally, the representation of short texts in this format may be useless to classification algorithms since most of the values of the representing vector will be 0 — adds Igor Kołakowski. Using semantic analysis, they try to understand how their customers feel about their brand and specific products.
