Abstract

The present invention provides methods and systems for delivering Internet-derived content to mobile devices with non-persistent connectivity. The methods include the creation of a small, high-quality, representative subset of content from the Internet, which is delivered to the mobile devices. The systems and methods allow updating of Internet-derived content present on the mobile devices. Further, the systems and methods allow delivery and updating of the Internet-derived content based on user interests. Systems and methods for enabling commercial transactions, using a device with non-persistent connectivity have been provided in the present invention.

Claims

1. A system for delivering Internet-derived content on a Device not having a persistent connection to the internet comprising means for enabling a user to browse or search a cache which is a small, representative subset of Internet-derived content elements on the Device, means for updating the cache at selected times by incrementally replacing some of the content stored in the cache, and means for controlling the update by relating the update process to the user'"'"'s stored profile.

2. The system of claim 1 wherein the each element of cached content is designated as a member of a group selected from the categories of Slow Web, Fast Web, and Personal Web, where Slow Web denotes content that is infrequently updated and has relatively high term coverage;

Fast Web denotes content that is updated frequently; and

Personal Web denotes content relevant to a user profile.

3. The system of claim 1 further comprising Crawler means for traversing the Internet and copying content onto temporary storage means, Summarizer means for analysing the copied content to select that content that is to be placed into the device cache, Update Server means for delivering selected content to one or more Clients, which are connected to the Update Server using a connection having total bandwidth equal or greater than that of the Device.

10. The system of claim 1 wherein the cache of content elements is divided into blocks, and each block of cached content has associated therewith one or more subject tags, and wherein the set of all blocks having a common subject tag is updated during a single update session.

11. The system of claim 1 wherein each element of cached content has associated therewith one or more timestamp tags, and wherein the set of all elements having a common timestamp tag is updated during a single update session.

12. The system of claim 2 wherein membership of cached content in the Personal Web Category is determined with reference to the stored user profile.

13. The system of claim 12 wherein the stored user profile is modified by personal information mining means for identifying personalized information stored on at least one of (a) stored on the user'"'"'s personal computer;

(b) stored on the Device and (c) stored on electronic devices used by the user for storage of information;

(d) stored on servers accessible to the user; and

(e) a memory, as a result of one or more explicit responses by the user to one or more requests for terms.

14. The system of claim 12 wherein at least some elements in the Personal Web category are located by determining one or more geographic locations of interest to the user, locating internet content relevant to those locations, and placing the located elements into the cache.

15. The system of claim 14 wherein at least one geographic location is derived from a GPS, a cellular triangulation, a calendar entry, or an RFID signal.

4. A method of forming a small, representative subset of content selected from a plurality of sources comprising,

determining a coverage set comprising a set of terms to be included in the subset of content;

computing a CoverageRank score for each element of content; and

identifying those elements having membership in the subset by application of predefined membership criteria.

5. The method of claim 4 wherein the CoverageRank score is computed by the steps comprising,

determining the Coverage Breadth of a content element;

determining the Coverage Depth of a content element;

determining the element characteristics, including the degree of independence of the

element;

determining the importance of the element;

evaluating subjective criteria about each element, if present; and

computing CoverageRank as a function of Coverage Breadth, Coverage Depth, element characteristics, element importance and subjective criteria.

6. The method of claim 4 wherein the CoverageRank is, at least in part, based upon the meaning of terms within an element of content.

7. The method of claim 5 wherein subjective criteria comprise at least one of

required terms;

required term meanings;

required elements;

excluded terms;

excluded elements; and

term weightings.

8. The method of claim 5 wherein CoverageSet is, at least in part, based upon a domain-specific dictionary, related to a predetermined knowledge domain of interest to a user.

9. The method of claim 5 wherein the CoverageSet is, at least in part, based upon a set of terms excluding a set of terms predetermined to have a lower information value than the remaining terms.

16. A method for enabling commercial transactions using devices without a real-time connection to a transaction server comprising the steps of:

transmitting an offer element from a transaction server to a device;

disconnecting the device from all transaction servers; and

then

presenting the offer element to a user;

accepting from the user an assent to the offer;

storing the conditions of the user assent in a memory;

completing the transaction with the user;

connecting the device to a transaction server at a time after accepting the assent; and

communicating the assent and the stored conditions to the transaction server.
