Semantic memory includes things that are common knowledge, such as the names of colors, the sounds of letters, the capitals of countries and other basic facts acquired over a lifetime.
Ideas in the human brain are semantically linked, meaning that firing one set of neurons in your brain primes related neurons. These links allow for localized querying when responding to a question, so that humans do not need to sift through their entire knowledge set before creating an answer.
Amelia can be taught to emulate this capability, so that she can retrieve information from a wider and complex set of knowledge. Amelia stores the associations between facts and concepts within her semantic memory, in the same way as humans. She can then apply the knowledge from her semantic memory, including a company's standard operating procedures (SOPs) and policy documents, to future conversations with customers and employees.
