User model-improvement-data-driven selection and update of user-oriented recognition model of a given type for word recognition at network server

A method for recognizing an input pattern stored in a user station using a recognition unit of a server station;

• the server station and the user station being connected via a network;
• the recognition unit being operative to recognize the input pattern using a model collection of at least one recognition model;
• the method comprising:
• performing an initial recognition enrolment step, comprising transferring model improvement data associated with a user of the user station from the user station to the recognition unit;
• and associating the user of the user station with a user identifier;
• and
• for a recognition session between the user station and the server station, transferring a user identifier associated with a user of the user station and an input pattern representative of time sequential input generated by the user from the user station to the server station;
• and using the recognition unit to recognize the input pattern by incorporating at least one recognition model in the model collection which reflects the model improvement data associated with the user;
• characterized:
• in that the server comprises a plurality of different user-oriented recognition model sets, each set of a same type;
• in that the recognition enrolment step comprises selecting a user-oriented recognition model from a set of a same type in dependence on the model improvement data associated with the user;
• and storing an indication of the selected user-oriented recognition model in association with the user identifier;
• and
• in that the step of recognizing the input pattern comprises retrieving a user-oriented recognition model associated with the user identifier transferred to the server station and incorporating the retrieved user-oriented recognition model in the model collection.
