One of the most useful NLP tasks is sentiment analysis \u2013 a method for the automatic detection of emotions behind the text. These refer to techniques that represent words as vectors in a continuous vector space and capture semantic relationships based on co-occurrence patterns. Semantic analysis stands as the cornerstone in navigating the complexities of unstructured data, revolutionizing how computer science approaches language comprehension. Its prowess in both lexical semantics and syntactic analysis enables the extraction of invaluable insights from diverse sources.<\/p>\n<\/p>\n One of the simplest and most popular methods of finding meaning in text used in semantic analysis is the so-called Bag-of-Words approach. Thanks to that, we can obtain a numerical vector, which tells us how many times a particular word has appeared in a given text. In syntactic analysis, sentences are dissected into their component nouns, verbs, adjectives, and other grammatical features. To reflect the syntactic structure of the sentence, parse trees, or syntax trees, are created. The branches of the tree represent the ties between the grammatical components that each node in the tree symbolizes. Syntax is the grammatical structure of the text, whereas semantics is the meaning being conveyed.<\/p>\n<\/p>\n In the above sentence, the speaker is talking either about Lord Ram or about a person whose name is Ram. Homonymy refers to the case when words are written in the same way and sound alike but have different meanings. Latent Semantic Analysis (LSA), also known as Latent Semantic Indexing (LSI), is a technique in Natural Language Processing (NLP) that uncovers the latent structure in a collection of text. It is particularly used for dimensionality reduction and finding the relationships between terms and documents.<\/p>\n<\/p>\n NLP has many applications in various domains, such as business, education, healthcare, and finance.
