System and Method for Change Detection of Information or Type of Data

Abstract

A method is provided of determining the how information from any information system changes over time. WebPages A through WebPages Z with nodes A through Z, are located, where A through Z are integers. Timestamp values for each of a node from A through Z are retrieved. Timestamp values from A are subtracted to create a denominator time value. A distance between the nodes A through Z is determined by calculating a number of edges in the digraph to create a numerator value. The numerator value is divided by the distance to provide a velocity value.

1 . A method of determining how information from any information system changes over time, comprising:
 locating web pages A through WebPages Z with nodes A through Z, where A through Z are integers;   retrieving timestamp values for each of a node from A through Z;   subtracting timestamp values from A to create a denominator time value;   determining a distance between the nodes A through Z by calculating the number of edges in the digraph to create a numerator value; and   dividing the numerator value by the distance to provide a velocity value.   
     
     
         2 . A method of determining how information changes from the internet changes over time, comprising:
 located at least a first webpage with a first node and a second webpage with a second node;   retrieving a first timestamp value of when the first node was published;   retrieving a second timestamp value of when the second node was published;   subtracting the second timestamp value from the first timestamp value to create a denominator time value;   determining a distance between the first and second nodes; and   dividing the denominator time value by the distance to provide a velocity value.   
     
     
         3 . The method of  claim 2 , wherein timestamps from more than the first and a second web pages are retrieved. 
     
     
         4 . The method of  claim 2 , wherein the distance is the shortest distance between the first and second nodes. 
     
     
         5 . The method of  claim 2 , wherein a number of edges between the first and second nodes is determined. 
     
     
         6 . The method of  claim 2 , wherein the changes are selected from at least one of, growth, decay and maintenance of a same state. 
     
     
         7 . The method of  claim 2 , wherein the velocity value is used to determine how a producer, receiver, observer or transmitter, of information changes over time. 
     
     
         8 . The method of  claim 2 , wherein the velocity value is used to determine how any type of information changes over time. 
     
     
         9 . The method of  claim 2 , wherein the velocity value is a velocity of at least one of, RFID's, supply-changing logistics, consumer packaged good purchase rates, UPC, advertisements, operating systems, computer applications, mobile information systems, networks, interactive video game devices, game consoles, game controllers and software for operating games, videos, photographs, audio, digital media in any form and electronic transmission of information 
     
     
         10 . The method of  claim 2 , wherein <issued>, <created> and <modified> tags and other indication of time is used to determine the timestamp. The other information is any HTML, XML, WML, or any markup or programming language that contains code to indicate a time value.
