1. An information handling apparatus in which textual metadata is generated and associated with a current information item based on metadata from a plurality of other information items, the apparatus comprising: a processor configured to perform as a property detector and configured to detect one or more predetermined properties of the current information item, the information items comprising audio and/or video data, and the property detector configured to detect one or more properties of the audio and/or video data; the processor also configured to perform as a subset detector and configured to detect a subset of the plurality of other information items, the subset being other information items which have the one or more predetermined properties most similar to the one or more predetermined properties of the current information item; a display arrangement configured to display to a user a selectable list of one or more of the most frequently occurring words and/or phrases within textual metadata associated with the subset of the plurality of other information items; a selector configured to receive a selection from the user of one or more of the displayed most frequently occurring words and/or phrases from the selectable list for use in textual metadata and to associate the words and/or phrases in the selection with the current information item; and a feature vector generator configured to generate a feature vector comprising feature data values indicative of the one or more predetermined properties of the current information item, and the subset detector is configured to detect those information items having a feature vector having a shortest Euclidean distance from the feature vector of the current information item.
