A system which allows a user to teach a computational device how to perform complex, repetitive tasks that the user usually would perform using the device's graphical user interface (GUI) often but not limited to being a web browser. The system includes software running on a user's computational device. The user “teaches” task steps by inputting natural language and demonstrating actions with the GUI. The system uses a semantic ontology and natural language processing to create an explicit representation of the task that is stored on the computer. After a complete task has been taught, the system is able to automatically execute the task in new situations. Because the task is represented in terms of the ontology and user's intentions, the system is able to adapt to changes in the computer code while still pursuing the objectives taught by the user.

Several different embodiments of an electronic document delivery system are described including a client machine (e.g., a palmtop / handheld computer or wireless communication device) coupled to a transcoder proxy. One embodiment of the system allows a client machine with limited resources to support JAVASCRIPT. The transcoder proxy receives an electronic document in a first digital format (e.g., HTML or XML). A JAVASCRIPT event may be associated with an element of the document including JAVASCRIPT code executed in response to the JAVASCRIPT event. The transcoder proxy assigns a unique identifier to the element, and forms a model of a logical structure of the document (e.g., a document object model or DOM). The transcoder proxy uses the model to produce an “original” script including a portion of the document expressed in a second digital format (e.g., a scripting language), and provides the original script to the client machine. The client machine uses the original script to display / present the document portion. The client machine associates the JAVASCRIPT event with the element identifier, generates the JAVASCRIPT event in response to user input, and provides JAVASCRIPT event information and the associated identifier to the transcoder proxy. The transcoder proxy accesses the element within the model using the identifier, executes the JAVASCRIPT code producing a result, uses the model and the result to produce a “modification” script, and provides the modification script to the client machine. The client machine uses the modification script to modify the displayed / presented portion of the document.

The Document Object Model (DOM) of a sampled web page is used to create a rule that extracts item-related data from web pages having a similar DOM structure to the sampled web page. In response to a user request for such a web page, the rule is retrieved from a data server based on the page's URL, and is applied to the DOM of the web page to extract item-identifying data. The item is then identified—preferably by the data server—by matching the item-identifying data to an item in a database. Supplemental information about the item is then retrieved from the database and supplied to the user's computer for viewing in conjunction with the requested page. In a preferred embodiment, the rule is retrieved from the data server and applied to the web page by a client application that runs in conjunction with a web browser.

A system for manipulating a document object model is provided. The system comprises a collection of document object model behavior elements, and a collection of scripts for performing actions associated with the set of behavior elements. Each behavior element comprises a name following a predetermined naming convention, an event attribute for associating the behavior element to an event, and other attributes for describing features of the behavior element. Each script is associated with a behavior element.
