Messaging arrangement

A method of processing received information transmissions transmitted from a transmitting station, the transmissions being of a type where there is provided in at least one of said transmissions classification data formatted to comprise at least two portions each serving to indicate a classification of the associated information transmission content, wherein one of the at least two portions serves to indicate the classification at a first hierarchical level and another one of the at least two portions serves to indicated the classification at a second hierarchical level, the classification indicated at the second hierarchical level being a sub-classification of the classification indicated at the first hierarchical level, said method comprising the steps of:

• analysing said classification data to determine whether the one of the at least two portions that serves to indicate a classification at the first hierarchical level indicates a classification that corresponds to a classification previously deemed to be of interest, and
• in the event said first hierarchical level classification does so correspond;
• analysing said classification data to determine whether the another one of the at least two portions serves to indicate a classification at the second hierarchical level that corresponds to a classification previously deemed to be of interest;
• and
• optionally further processing said received information message content in the event said first and second level hierarchical level classifications correspond to those classifications deemed to be of interest by a user.

A processing apparatus for processing information transmissions received from a transmitting station, the transmissions being of a type where there is provided in at least one of said transmissions classification data formatted to comprise at least two portions each serving to indicate a classification of the associated information transmission content, wherein one of the at least two portions serves to indicate the classification at a first hierarchical level and another one of the at least two portions serves to indicated the classification at a second hierarchical level, the classification indicated at the second hierarchical level being a sub-classification of the classification indicated at the first hierarchical level, said apparatus comprising:

• first analysing means for analysing said classification data to determine whether the one of the at least two portions that serves to indicate a classification at the first hierarchical level indicates a classification that corresponds to a classification previously deemed to be of interest, and
• second analysing means for analysing said classification data in the event said first hierarchical level classification does so correspond, said second analysing means serving to determine whether the another one of the at least two portions serves to indicate a classification at the second hierarchical level that corresponds to a classification previously deemed to be of interest;
• and
• means for optionally further processing said received information transmissions in the event said first and second level hierarchical level classifications correspond to those classifications deemed to be of interest by a user.
