By knowing the structure of sentences, we can start trying to understand the meaning of sentences. We start off with the meaning of words being vectors but we can also do this with whole phrases and sentences, where the meaning is also represented as vectors. And if we want to know the relationship of or between sentences, we train a neural network to make those decisions for us. Insurance companies can assess claims with natural language processing since this technology can handle both structured and unstructured data.

LLMs use a type of neural network architecture known as Transformer, which enables them to understand the context and relationships between words in a sentence. This understanding is crucial for the model to generate coherent and contextually relevant responses. Another crucial aspect of semantic analysis is understanding the relationships between words. Words in a sentence are not isolated entities; they interact with each other to form meaning.

The semantic analysis does throw better results, but it also requires substantially more training and computation. Syntactic analysis involves analyzing the grammatical syntax of a sentence to understand its meaning. In semantic analysis, word sense disambiguation refers to an automated process of determining the sense or meaning of the word in a given context. As natural language consists of words with several meanings (polysemic), the objective here is to recognize the correct meaning based on its use.
