Semantic Compositionality

Semantic compositionality is the principle that the meaning of a complex expression, such as a sentence, can be understood by considering the meanings of its individual parts and how they combine. For instance, in the sentence "The cat sits on the mat," we derive its overall meaning from understanding what "cat," "sits," and "mat" mean, as well as how they relate to each other. This concept is crucial in language and communication, enabling us to interpret new sentences based on known words and structures, facilitating comprehension and knowledge sharing.
