Abstract

A procedure for selecting and storing data elements communicated from a common database to users of the database utilizing a communication link between each transmitter and a concomitant receiver accessible by the user. The transmitted information is augmented with attributes which are used at the receiver to select and then store locally only that information of interest to each receiver'"'"'s user, wherein the attributes and the user selection pattern determine the criteria for storing information locally. Attributes include: utility of each data element in time; interest categories and level of interest for each of the categories determined for the collective users; repeat time to the data element; and a hyperlink to associated data elements.

Claims

1. A method for receiving data elements by each of a plurality of users of the data elements, the data elements being communicated from a common database wherein:

(i) interest categories for the database are defined which express the collective interest of the users;

(ii) at least one of the interest categories is assigned to each data element; and

(iii) data attributes for each of the data elements are identified, one of the data attributes being an interest level for each of the interest categories such that each interest level expresses an estimate of the collective interest of the users in each of the interest categories assigned to each data element, the method comprising the steps of

(a) generating a user profile indicative of data elements of interest for each particular user,

(b) selecting and locally storing data elements of interest for each particular user in correspondence to the selections of each user with respect to the communicated data elements and with reference to the user profile, and

(c) modifying the user profile in correspondence to the data attributes of data elements selected by each particular user, and returning to step (b).

2. The method as recited in claim 1 wherein at least one data element is indicative of physical parameters to control a display device and further including the step of displaying the locally stored data elements on the display device in response to user selection of the locally stored data elements, the step of displaying including the step of controlling the display device with the physical parameters expressed by said at least one data element.

3. The method as recited in claim 1 wherein another of the attributes is a utility attribute which expresses the usefulness of each of the data elements as a function of time, and wherein the step of modifying includes the step of modifying the user profile in correspondence to the utility function.

4. A method for receiving data elements and associated data attributes both communicated from a common database to a user of the data elements, the method comprising the steps of

a) generating a user profile indicative of data elements of interest to the user,

(b) selecting and locally storing data elements of interest to the user in correspondence to the selections of the user with respect to the communicated data elements and with reference to the user profile,

(c) synthesizing a home page to display disjointed groups of locally stored data elements on a display device,

(d) navigating among disjoint groups of the locally stored data elements with reference to the home page,

(e) displaying the locally stored data elements on the display device in response to user selection of the locally stored data elements, and

(f) modifying the user profile in correspondence to the data attributes of data elements selected by the user, and returning to step (b).

5. A method for receiving data elements communicated from a common database to each of a plurality of users of the data elements, the data elements from the common database being arranged as follows:

(i) interest categories for the database are defined which express the collective interest of the users;

(ii) at least one of the interest categories is assigned to each data element; and

(iii) data attributes for each of the data elements are identified, one of the data attributes being an interest level for each of the interest categories wherein each interest level expresses an estimate of the collective interest of the users in each of the interest categories assigned to each data element, and another of the attributes being at least one data element is a special page data element and the associated data attribute of said page data element indicates the relative value of the page data element as a home page, the method comprising the steps of

(a) generating a user profile indicative of data elements of interest for each user,

(b) selecting and locally storing data elements of interest for each user in correspondence to the selections of each user with respect to the communicated data elements and with reference to the user profile,

(c) displaying the locally stored data elements on a display device in response to user selection of the locally stored data elements,

(d) synthesizing a home page to display disjointed groups of locally stored data elements on the display device, the step of synthesizing including the step of weighting the relative value in selecting the home page,

(e) navigating among disjoint groups of the locally stored data elements with reference to the home page, and

(f) modifying the user profile in correspondence to the data attributes of data elements selected by each user, and returning to step (b).

6. The method as recited in claim 5 wherein the step of navigating includes the steps of marking certain data elements as primary navigational pathways and displaying the locally stored data elements in correspondence to said certain data elements.

7. Circuitry for receiving data elements communicated from a common database to each of a plurality of users of the data elements, the data elements being communicated from a common database wherein:

(i) interest categories for the database are defined which express the collective interest of the users;

(ii) at least one of the interest categories is assigned to each data element; and

(iii) data attributes for each of the data elements are identified, one of the data attributes being an interest level for each of the interest categories wherein each interest level expresses an estimate of the collective interest of the users in each of the interest categories assigned to each data element, the circuitry comprising

(a) means for generating a user profile indicative of data elements of interest for each user,

(b) means, coupled to said means for generating, for selecting and locally storing data elements of interest for each user in correspondence to the selections of each user with respect to the communicated data elements and with reference to the user profile, and

(c) means, responsive to said means for selecting and for storing and coupled to said means for generating, for modifying the user profile in correspondence to the data attributes of data elements selected by each user.
