Information handling

An information handling system in which information items are mapped to respective nodes in an array of nodes by mutual similarity of said information items, such that similar information items map to nodes at similar positions in said array of nodes;

• there being a mapping relationship between frequencies of occurrence, within an information item, of each of a concordance of information features and nodes in said array of nodes;
• said system comprising:
• a detector, operable in respect of an information item to be processed, to detect a closest node in said array of nodes, said closest node being that node for which said mapping relationship provides a closest match with an information item to be processed;
• a selector to select a group of nodes near, in said array, to said closest node;
• and
• logic to modify said mapping relationship so that said closest node and said group of nodes are brought generally closer to said information item to be processed;
• in which, for the purposes of selecting said group of nodes, said array wraps around so that a peripheral edge of said array is treated as adjacent to an opposite peripheral edge of said array.

An information handling method in which information items are mapped to respective nodes in an array of nodes by mutual similarity of said information items, such that similar information items map to nodes at similar positions in said array of nodes;

• there being a mapping relationship between frequencies of occurrence, within an information item, of each of a concordance of information features and nodes in said array of nodes;
• said method comprising the steps of:
• displaying a representation of at least some of said nodes as a two-dimensional display array of display points within a display area on a user display;
• in which, for the purposes of displaying said nodes, said array wraps around so that a peripheral edge of said array is treated as adjacent to an opposite peripheral edge of said array.

• there being a mapping relationship between frequencies of occurrence, within an information item, of each of a concordance of information features and nodes in said array of nodes;
• said system comprising:
• a graphical user interface to display a representation of at least some of said nodes as a two-dimensional display array of display points within a display area on a user display;
• in which, for the purposes of displaying said nodes, said array wraps around so that a peripheral edge of said array is treated as adjacent to an opposite peripheral edge of said array.
