Task/domain segmentation in applying feedback to command control

A method for responding to a current user command associated with one of a plurality of task/domains, comprising:

• determining the current task/domain with which the current user command is associated;
• determining a current response to the current user command on the basis of previously gathered and stored feedback data associated with the current task/domain;
• communicating to the user the current response;
• receiving from the user current feedback data regarding the current response;
• and
• storing the current feedback data,
• wherein the stored current feedback data is added to cumulative feedback data gathered and stored during previous iterations of the method and associated with the current task/domain.

A computer-readable storage medium storing program code executable by a program-controlled apparatus, said code being operable to cause the apparatus to:

• determine the current task/domain with which the current user command is associated;
• determine a current response to the current user command on the basis of previously gathered and stored feedback data associated with the current task/domain;
• communicate to the user the current response;
• receive from the user current feedback data regarding the current response;
• and
• store the current feedback data,
• wherein the stored current feedback data is added to cumulative feedback data gathered and stored during previous executions of the code and associated with the current task/domain.

An apparatus for responding to a current user command associated with one of a plurality of task/domains, the apparatus comprising:

• a digital storage device that stores cumulative feedback data gathered during previous operations of the apparatus and segregated in accordance with the plurality of task/domains;
• a first digital logic device that determines the current task/domain with which the current user command is associated;
• a second digital logic device that determines a current response to the current user command on the basis of that portion of the stored cumulative feedback data associated with the current task/domain;
• a first communication interface that communicates to the user the current response;
• and
• a second communication interface that receives from the user current feedback data regarding the current response,
• wherein the current feedback data is added to the cumulative feedback data stored in said digital storage device and associated with the current task/domain.

A method of locating items containing language using a particular vocabulary, said method comprising:

• crawling nodes on a network to extract from the nodes identifiers for each of a plurality of vocabularies;
• compiling an index of the extracted vocabulary identifiers;
• receiving a command associated with an item using one of the plurality of vocabularies;
• and
• finding, using the index of vocabulary identifiers, the items using the one vocabulary.
