Information processing apparatus, information processing method, and program

An information processing method for an information processing apparatus capable of communicating via a network, comprising:

• a search step of performing an information search process on the network using input search criteria;
• a registration step of registering the search criteria used by the search step in the search process;
• a first search result retrieval step of retrieving first search results produced by the search step using the search criteria;
• a re-search step of searching the network for information again after the retrieval of the first search results using the search criteria registered by the registration step;
• a second search result retrieval step of retrieving second search results produced by the re-search step using the search criteria;
• and
• a difference detection step of detecting difference information from retrieved information by comparing the first search results and the second search results.

A program for an information processing apparatus capable of communicating via a network, wherein the program makes the computer execute:

• a search step of performing an information search process on the network using input search criteria;
• a registration step of registering the search criteria used by the search step in the search process;
• a first search result retrieval step of retrieving first search results produced by the search step using the search criteria;
• a re-search step of searching the network for information again after the retrieval of the first search results using the search criteria registered by the registration step;
• a second search result retrieval step of retrieving second search results produced by the re-search step using the search criteria;
• and
• a difference detection step of detecting difference information from retrieved information by comparing the first search results and the second search results.
