The content of a large number of primary-content sources is analyzed and keyword and/or other context-providing information is extracted from the primary-content sources. The keyword and/or other context-providing information is used to index the primary-content sources into an index according to a hierarchical taxonomy; the hierarchical taxonometric index is used to identify primary-content sources with which a given item of invitational content correlates; and the given item of invitational content is delivered to a user in response to the user accessing a primary-content source with which the given item of invitational content correlates. ## Claims ### Claim 1 A method comprising: analyzing, by a processor, a first content of a primary-content source to identify at least a first term from the first content determined to be relevant to the primary-content source based on a number of times the first term appears in the first content, wherein analyzing the first content comprises: text-processing the first content to identify non-extraneous terms; ignoring extraneous terms determined to carry no meaningful substantive or contextual information; converting the non-extraneous terms into their base form by eliminating suffixes; normalizing the non-extraneous terms to lowercase letters; and determining a number of times each of the non-extraneous terms appears in the first content; analyzing, by the processor, a second content of an invitational content item to identify at least a second term from the second content determined to be relevant to the invitational content item based on a number of times the second term appears in the second content; determining, by the processor, that primary-content source and the invitational content item are correlated when the primary-content source is assigned to a first index category in a predetermined hierarchical taxonomy based on the first term and the invitational content item is assigned to the first index category in the predetermined hierarchical taxonomy based the second term; and when the primary-content source and the invitational content item are correlated, delivering, by the processor, the invitational content item to a user in response to the user accessing the primary-content source. ### Claim 2 (depends on 1) The method of claim 1, wherein the first index category in the predetermined hierarchical taxonomy is associated with at least one target term. ### Claim 3 (depends on 2) The method of claim 2, further comprising: comparing the first term to the at least one target term associated with the first index category in the predetermined hierarchical taxonomy; and upon a determination that the at least one target term includes the first term, assigning the primary-content source to the first index category in the predetermined hierarchical taxonomy. ### Claim 4 (depends on 2) The method of claim 2, further comprising: comparing the second term to the at least one target term associated with the first index category in the predetermined hierarchical taxonomy; and upon a determination that the at least one target term includes the second term, assigning the invitational content item to the first index category in the predetermined hierarchical taxonomy. ### Claim 5 (depends on 1) The method of claim 1, wherein the first term is the non-extraneous term determined to appear in the first content most frequently. ### Claim 6 A content delivery system comprising: a processor; and a memory containing instructions that, when executed, cause the processor to: analyze a first content of a primary-content source to identify at least a first term from the first content determined to be relevant to the primary-content source based on a number of times the first term appears in the first content, wherein analyzing the first content comprises: text-processing the first content to identify non-extraneous terms; ignoring extraneous terms determined to carry no meaningful substantive or contextual information; converting the non-extraneous terms into their base form by eliminating suffixes; normalizing the non-extraneous terms to lowercase letters; and determining a number of times each of the non-extraneous terms appears in the first content; analyze a second content of an invitational content item to identify at least a second term from the second content determined to be relevant to the invitational content item based on a number of times the second term appears in the second content; determine that primary-content source and the invitational content item are correlated when the primary-content source is assigned to a first index category in a predetermined hierarchical taxonomy based on the first term and the invitational content item is assigned to the first index category in the predetermined hierarchical taxonomy based the second term; and when the primary-content source and the invitational content item are correlated, deliver the invitational content item to a user in response to the user accessing the primary-content source. ### Claim 7 (depends on 6) The content delivery system of claim 6, wherein the first index category in the predetermined hierarchical taxonomy is associated with at least one target term. ### Claim 8 (depends on 7) The content delivery system of claim 7, wherein the instructions further cause the processor to: compare the first term to the at least one target term associated with the first index category in the predetermined hierarchical taxonomy; and upon a determination that the at least one target term includes the first term, assign the primary-content source to the first index category in the predetermined hierarchical taxonomy. ### Claim 9 (depends on 7) The content delivery system of claim 7, wherein the instructions further cause the processor to: compare the second term to the at least one target term associated with the first index category in the predetermined hierarchical taxonomy; and upon a determination that the at least one target term includes the second term, assign the invitational content item to the first index category in the predetermined hierarchical taxonomy. ### Claim 10 (depends on 6) The content delivery system of claim 6, wherein the second term is the non-extraneous term determined to appear in the second content most frequently. ### Claim 11 A non-transitory computer-readable medium containing instruction that, when executed by a computing device, cause the computing device to: analyze a first content of a primary-content source to identify at least a first term from the first content determined to be relevant to the primary-content source based on a number of times the first term appears in the first content, wherein analyzing the first content comprises: text-processing the first content to identify non-extraneous terms; ignoring extraneous terms determined to carry no meaningful substantive or contextual information; converting the non-extraneous terms into their base form by eliminating suffixes; normalizing the non-extraneous terms to lowercase letters; and determining a number of times each of the non-extraneous terms appears in the first content; analyze a second content of an invitational content item to identify at least a second term from the second content determined to be relevant to the invitational content item based on a number of times the second term appears in the second content; determine that primary-content source and the invitational content item are correlated when the primary-content source is assigned to a first index category in a predetermined hierarchical taxonomy based on the first term and the invitational content item is assigned to the first index category in the predetermined hierarchical taxonomy based the second term; and when the primary-content source and the invitational content item are correlated, deliver the invitational content item to a user in response to the user accessing the primary-content source. ### Claim 12 (depends on 11) The non-transitory computer-readable medium of claim 11, wherein the first index category in the predetermined hierarchical taxonomy is associated with at least one target term. ### Claim 13 (depends on 12) The non-transitory computer-readable medium of claim 12, wherein the instructions further cause the computing device to: compare the first term to the at least one target term associated with the first index category in the predetermined hierarchical taxonomy; and upon a determination that the at least one target term includes the first term, assign the primary-content source to the first index category in the predetermined hierarchical taxonomy. ### Claim 14 (depends on 12) The non-transitory computer-readable medium of claim 12, wherein the instructions further cause the computing device to: compare the second term to the at least one target term associated with the first index category in the predetermined hierarchical taxonomy; and upon a determination that the at least one target term includes the second term, assign the invitational content item to the first index category in the predetermined hierarchical taxonomy. ### Claim 15 (depends on 11) The non-transitory computer-readable medium of claim 11, wherein the first term is the non-extraneous term determined to appear in the first content most frequently.
