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.

In other words, we can say that lexical semantics is the relationship between lexical items, meaning of sentences and syntax of sentence. Semantic analysis techniques involve extracting meaning from text through grammatical analysis and discerning connections between words in context. This process empowers computers to interpret words and entire passages or documents.

This is one of the many challenges that researchers in the field of Semantic Analysis are working to overcome. For example, the sentence “The cat sat on the mat” is syntactically correct, but without semantic analysis, a machine wouldn’t understand what the sentence actually means. It wouldn’t understand that a cat is a type of animal, that a mat is a type of surface, or that “sat on” indicates a relationship between the cat and the mat. Understanding these terms is crucial to NLP programs that seek to draw insight from textual information, extract information and provide data. It is also essential for automated processing and question-answer systems like chatbots. But before getting into the concept and approaches related to meaning representation, we need to understand the building blocks of semantic system.

For instance, in the sentence “John ate the cake,” “John” is the agent because he is the one who is doing the action of eating. The idiom “break a leg” is often used to wish someone good luck in the performing arts, though the literal meaning of the words implies an unfortunate event. In the sentence “John gave Mary a book”, the frame is a ‘giving’ event, with frame elements “giver” (John), “recipient” (Mary), and “gift” (book). Meronomy refers to a relationship wherein one lexical term is a constituent of some larger entity like Wheel is a meronym of Automobile. Synonymy is the case where a word which has the same sense or nearly the same as another word. Semantic analysis, on the other hand, is crucial to achieving a high level of accuracy when analyzing text.
