Semantic analysis, on the other hand, explores meaning by evaluating the language’s importance and context. Although they both deal with understanding language, they operate on different levels and serve distinct objectives. Let’s delve into the differences between semantic analysis and syntactic analysis in NLP. Semantic similarity is the measure of how closely two texts or terms are related in meaning.

Upon parsing, the analysis then proceeds to the interpretation step, which is critical for artificial intelligence algorithms. For example, the word ‘Blackberry’ could refer to a fruit, a company, or its products, along with several other meanings. Moreover, context is equally important while processing the language, as it takes into account the environment of the sentence and then attributes the correct meaning to it. Semantic analysis helps in processing customer queries and understanding their meaning, thereby allowing an organization to understand the customer’s inclination. Moreover, analyzing customer reviews, feedback, or satisfaction surveys helps understand the overall customer experience by factoring in language tone, emotions, and even sentiments. We could also imagine that our similarity function may have missed some very similar texts in cases of misspellings of the same words or phonetic matches.
