Abstract

With the purpose of automatically and efficiently finding and selecting a collection of software functions truly useful for a user from a collection of software functions and of adequately and easily judging whether the software function selected by the user should be adopted or not, the computer system according to the present invention comprises task description holding means for holding a collection of task descriptions formally describing individual utilization patterns of various types of software functions, and filtering means for finding and selecting a task description describing a utilization pattern, not tried by the user in the past and regarded as useful for the user, from a collection of task descriptions held by said task description holding means and for disclosing it to the user. By adding the task description selected by the filtering means to a task model, said task model can be changed during task execution.

Claims

1. A computer system, comprising:

task model holding means for holding a task model, which is a collection of knowledge, modeled after task execution pattern of a user;

context information holding means for holding context information, which is a knowledge to represent a context of task execution of the user, sequentially calculated and updated based on input information from task model and operation series of the user;

task execution means for making access to software functions necessary to task execution wanted by the user referring to the task model and the context information based on input operation by the user and for converting the results of execution of the software functions to adequate expression to present to the user, referring to the task model and context information;

whereby there are further provided;

task description holding means for holding a collection of task descriptions formally describing individual utilization patterns of the software functions; and

filtering means for finding and selecting a task description describing utilization pattern, not tried by the user in the past and regarded as useful to the user, from a collection of task descriptions held by the task description holding means, and for disclosing it to the user.

2. A computer system according to claim 1, wherein said filtering means is provided with:

context-sensitive selection mechanism for selecting a task description suitable for context of the current task execution using said context information; and

context-sensitive disclosure mechanism for offering a chance for the user to try to use a utilization pattern of a task description selected by said context-sensitive selection mechanism in the context of actual task execution.

3. A computer system according to claim 1, wherein said filtering means is provided with:

a selection mechanism based on reliability for selecting a task description prepared or recommended by a reliable person, selected according to reliability evaluation values set explicitly by the user from a collection of task descriptions not tried by the user in the past;

a context-sensitive selection mechanism for selecting a task description suitable for a context of the current task execution using said context information; and

context-sensitive disclosure mechanism for offering a chance to try to use a utilization pattern of task description selected by the selection mechanism based on reliability and the context-sensitive selection mechanism in the context of actual task execution.
