Method and apparatus for deducing user intent and providing computer implemented services
First Claim
1. A computer implemented method for deducing user intent and providing computer implemented services comprising:
- (a) noticing a significant new event occurring within a computer system including;
(i) noticing that there is a new event;
(ii) matching said new event against a computer database of recognizable significant events;
(iii) creating a significant observation from a match of said new event into said database;
(iv) recording a delimiter value with said significant observation; and
(v) adding said significant observation to a set of significant observations which have occurred within said delimiter value;
(b) deducing an intent from said significant new event and from the context in which said new event occurred including;
(i) recognizing a possible intent from the new event from the context in which the new event occurred; and
(ii) determining a highest priority intent attributable to said new event in said context including;
(1) enumerating all possible intents from said new event in its context by matching said significant observations in said set against at least one template to determine all possible matches;
(2) prioritizing said possible intents by weighting said matches, said step of weighting said matches being accomplished by taking, for each template that there is at least one match, the ratio of a number of matching significant objects in said set to the number of positions in said template; and
(3) choosing a highest priority intent from said prioritized possible intents; and
(c) providing a service based upon said new event and said context.

Abstract
A method for deducing user intent and providing computer implemented services characterized by the steps of: a) noticing a significant new event occurring within the computer system; b) deducing an intent from the significant new event and from the context in which the new event occurred; and c) providing a service based upon the new event and its context. Significant events are those which the computer might be able to assist a user, and can be determined by matching the event into a database of recognizable events to make a significant observation. The deduction step takes a delimited set of significant observations and attempts to match the set against a number of intent templates. If there are multiple matches to the intent templates, the matches are ranked and a best guess is made to determine a deduced intent. Service is provided fulfilling all preconditions of a plan associated with the deduced intent, and by sequentially executing the steps of the plan. The apparatus of the present invention implements the method on a pen-based computer system.

2. A method of executing an operation on a computer system in response to high level information entered in the computer system, the method comprising the following steps:
-
recognizing as objects pieces of information entered on a display screen of the computer system, the objects each having a recognized object type, the object types recognized by the computer system including at least persons, shapes, and times; creating a set of objects from the information entered in the computer system, the set describing possible computer operations; comparing the object type of at least one of the objects in the set of objects so created with a plurality of task templates stored in the computer system, the task templates defining operations that can be performed with the computer system, the templates also having a plurality of associated preconditions; identifying one or more of said task templates having a precondition corresponding to an object type of at least one of the objects in said set; selecting a single task template from among the one or more task templates identified in the previous step by finding the task template having the best agreement with regard to the object types of all text or graphics objects in the set; and executing the task associated with the single task template if the preconditions associated with that template have been determined. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10)
