== A  web graph ==
The web graph refers to the entire network of interconnected web pages and links that make up the World Wide Web. A sub-graph, on the other hand, is a subset of the web graph that includes only a portion of the web pages and links.
The webgraph describes the directed links between pages of the World Wide Web. A graph, in general, consists of several vertices, some pairs connected by edges. In a directed graph, edges are directed lines or arcs. The webgraph is a directed graph, whose vertices correspond to the pages of the WWW, and a directed edge connects page X to page Y if there exists a hyperlink on page X, referring to page Y.<ref>https://en.wikipedia.org/wiki/Webgraph</ref>

There are several key differences between the web graph and sub-graphs:


# Size: The web graph is much larger than any individual sub-graph, as it includes all of the web pages and links on the World Wide Web. Sub-graphs, on the other hand, are typically much smaller, as they include only a portion of the web pages and links.
# Connectivity: The web graph is a highly interconnected network, with many web pages and links connecting different parts of the web. Sub-graphs, on the other hand, may be less interconnected, as they include only a portion of the web pages and links.
# Scope: The web graph includes all of the web pages and links on the World Wide Web, while sub-graphs are focused on a specific topic or area of interest. For example, a sub-graph might include only web pages and links related to a particular topic or domain.
# Purpose: The web graph serves as a model of the entire World Wide Web, while sub-graphs are often used for specific purposes, such as analyzing the structure or connectivity of a particular area of the web.


In summary, the web graph is the entire network of interconnected web pages and links that make up the World Wide Web, while sub-graphs are smaller subsets of the web graph that are focused on a specific topic or area of interest.

Web Science[1]


The web graph refers to the entire network of interconnected web pages and links that make up the World Wide Web. A sub-graph, on the other hand, is a subset of the web graph that includes only a portion of the web pages and links.

There are several key differences between the web graph and sub-graphs:

  1. Size: The web graph is much larger than any individual sub-graph, as it includes all of the web pages and links on the World Wide Web. Sub-graphs, on the other hand, are typically much smaller, as they include only a portion of the web pages and links.
  2. Connectivity: The web graph is a highly interconnected network, with many web pages and links connecting different parts of the web. Sub-graphs, on the other hand, may be less interconnected, as they include only a portion of the web pages and links.
  3. Scope: The web graph includes all of the web pages and links on the World Wide Web, while sub-graphs are focused on a specific topic or area of interest. For example, a sub-graph might include only web pages and links related to a particular topic or domain.
  4. Purpose: The web graph serves as a model of the entire World Wide Web, while sub-graphs are often used for specific purposes, such as analyzing the structure or connectivity of a particular area of the web.

In summary, the web graph is the entire network of interconnected web pages and links that make up the World Wide Web, while sub-graphs are smaller subsets of the web graph that are focused on a specific topic or area of interest.
