A computer-implemented method of performing named entity recognition in a client-server environment includes providing a first named entity recognition module operable with a client machine in the client-server environment and a second named entity recognition module operable with a server in the client-server environment. The method also includes performing named entity recognition on the client machine to identify one or more domain dependent named entities in a set of tokens and data assessable to the client machine and performing named entity recognition on the server to identify one or more domain independent named entities in the set of tokens and data assessable to the server. A task is completed using at least information related to the identified named entities from the client machine and the server.
