Discourse Integration depends upon the sentences that proceeds it and also invokes the meaning of the sentences that follow it. Syntactic Analysis is used to check grammar, word arrangements, and shows the relationship among the words. Named Entity Recognition (NER) is the process of detecting the named entity such as person name, movie name, organization name, or location. Implementing the Chatbot is one of the important applications of NLP. It is used by many companies to provide the customer’s chat services.

Lexical semantics is not a solved problem for NLP and AI, as it poses many challenges and opportunities for research and development. Some of the challenges are ambiguity, variability, creativity, and evolution of the opportunities are semantic representation, semantic similarity, semantic inference, and semantic evaluation. In the above sense, syntactic analysis or parsing may be defined as the process of analyzing the strings of symbols in natural language conforming to the rules of formal grammar.

NLP & Lexical Semantics

It is used in applications, such as mobile, home automation, video recovery, dictating to Microsoft Word, voice biometrics, voice user interface, and so on. Case Grammar was developed by Linguist Charles J. Fillmore in the year 1968. Case Grammar uses languages such as English to express the relationship between nouns and verbs by using the preposition. Augmented Transition Networks is a finite state machine that is capable of recognizing regular languages.

The words are transformed into the structure to show hows the word are related to each other. Discourse Integration The term “discourse integration” refers to a feeling of context. The meaning of any sentence is determined by the meaning of the sentence immediately preceding it. In addition, it establishes the meaning of the sentence that follows. The sentences that come before it play a role in discourse integration. That is to say, that statement or word is dependent on the preceding sentence or words.

Data Integration

Hence, under Compositional Semantics Analysis, we try to understand how combinations of individual words form the meaning of the text. Sentiment analysis can be used by financial institutions to monitor credit sentiments from the media. Financial firms can divide consumer sentiment data to examine customers’ opinions about their experiences with a bank along with services and products.
