US Patent 9852124 Dynamic portmanteau word semantic identification

An approach is provided to discover new portmanteau, such as when ingesting documents into a question answering (QA) system. The approach works by analyzing a words included in electronic documents and identifies words as being possible portmanteaus.

A meaning for the new portmanteau is then derived from the meanings of the candidate word meanings.
