Latent semantic analysis for text categorization using neural network

This data can then be converted into a dataframe using the Pandas library. To perform NLP operations on a dataframe, the Gensim library can be effectively used to carry out N-gram analysis apart from basic text processing. N-gram analysis helps you to understand the relative meaning by combining two or more words. If two words are combined, it is termed ‘Bi-gram,’ and the connection of three words is called ‘Tri-gram’ analysis. This analysis considers the association of words to understand the actual sentiment of the text. For instance, if Bi-gram analysis is performed on the text “battery performance is not good,” it will reflect a negative sentiment.

Semantic analysis is used by writers to provide meaning to their writing by looking at it from their point of view. An analyst examines a work’s dialect and speech patterns in order to compare them to the language used by the author. Semantics can be used by an author to persuade his or her readers to sympathize with or dislike a character. There are no universally shared grammatical patterns among most languages, nor are there universally shared translations among foreign languages. Interpretation is easy for a human but not so simple for artificial intelligence algorithms.
