Claim 7

The method of claim 1, wherein a message that includes a Uniform Resource Locator is determined to also include evaluation information about the resource located at the Uniform Resource Locator if: a. all of the following conditions are false: i. the message is marked private; ii. the domain name of the Uniform Resource Locator is the Uniform Resource Locator of a search engine; iii. the Uniform Resource Locator identified occurs in a quote from another message; iv. the Uniform Resource Locator occurs in Hypertext Markup Language code; v. the message author's e-mail username appears as a substring of the Uniform Resource Locator; vi. the message author's e-mail domain name appears as a substring of the Uniform Resource Locator; vii. the domain name of the organization of the message author appears as a substring of the Uniform Resource Locator; and viii. the Uniform Resource Locator occurs in the signature of the message; and b. if any one of the following conditions is true: i. the Uniform Resource Locator identified in step a occurs within from one to fifty words of one of the strings from the group: you, check, find, see, visit, try, look and recommend; and ii. the message subject line contains at least one of the strings from the group of: Frequently Asked Questions and FAQ.

Claim 8

The method of claim 1, wherein storing evaluation information about the resource includes storing at least one from the group of: the Uniform Resource Locator, words of the message preceding the occurrence of the Uniform Resource Locator, words of the message following the occurrence of the Uniform Resource Locator, the identity of the author of the message, and a unique message identifier.

Claim 9

The method of claim 1, wherein the message is comprised of a header portion and a body portion, and wherein storing evaluation information about the resource includes storing information from the header portion and information from the body portion of the message.

Claim 10

The method of claim 1, further comprising the step of fetching a copy of the resource located at the Uniform Resource Locator.

Claim 11

The method of claim 9, further comprising the step of storing in the database the contents of at least part of the fetched copy.

Claim 12

The method of claim 10, wherein said contents are stored in a condensed format.

Claim 13

The method of claim 9, further comprising the steps of: extracting a resource description from the contents of the fetched copy; and storing the resource description in the database.

Claim 14

The method of claim 12, further comprising the step of receiving a search request from a user.

Claim 15

The method of claim 13, wherein said user search request is a keyword search, and further comprising the steps of: searching the database to identify resources having information relevant to the user search request; and assigning a score to each resource identified as being relevant to the user search request, wherein the score is based at least partly upon the number of distinct messages that include both the Uniform Resource Locator of each said resource and evaluation information and the amount of information in each said resource that is relevant to the user search request.

Claim 16

The method of claim 14, further comprising the steps of: determining the maximum number of resources to be presented to a user on a page; sorting the resources by score from highest score to lowest; presenting the resources to the user in an order based at least partly upon the score of each resource.

Claim 17

The method of claim 15, further comprising the steps of determining the number of distinct evaluators for each resource determined to be relevant to the user search request determining the recency of evaluation information for each resource determined to be relevant to the user search request, and wherein the score of a resource is based at least partly upon the number of distinct evaluators and the recency of the evaluation information for the resource.

Claim 18

The method of claim 1, further comprising the step of determining the identity of an evaluator of a resource, and displaying the identity of the evaluator to a user.

Claim 19

The method of claim 14, further comprising the step of providing evaluation information included in the message to the user.

Claim 22

The system of claim 19, wherein said evaluation server fetches a copy of a resource through the network and stores said copy on a resource database, and wherein information from said copy is displayed to a user in response to a request from the user.
