Annotating articles

A non-transitory computer-readable medium containing instructions, the instructions comprising:

• one or more instructions which, when executed by at least one processor, cause the at least one processor to receive a first article that is retrieved from a first server;
• one or more instructions which, when executed by the at least one processor, cause the at least one processor to determine whether the first article satisfies first criteria based on content of the first article;
• one or more instructions which, when executed by the at least one processor, cause the at least one processor to annotate the first article with a first article type when the first article satisfies the first criteria;
• one or more instructions which, when executed by the at least one processor, cause the at least one processor to determine whether the first article satisfies second criteria based on information, other than the content of the first article, that is associated with the first article,
• where the information, that is associated with the first article, comprises a quantity of times that the first article is shared by particular users via one or more particular online applications;
• one or more instructions which, when executed by the at least one processor, cause the at least one processor to annotate the first article with a second article type when the first article satisfies the second criteria,
• where the second article type is different from the first article type,
• where the first article satisfies the second criteria when the quantity of times is greater than a quantity of times that another article about a topic of the article is shared, and
• where the second article type indicates that the quantity of times that the article is shared is greater than the quantity of times that the other article about the topic is shared;
• and
• store the first article in association with the topic of the article and at least one of the first article type or the second article type.

A server device comprising:

• a memory to store articles;
• and
• a processor to:
• receive a search query,
• select a first article, of the articles, that is responsive to the search query and is stored in association with a first particular article type that describes content of the first article,
• select a second article, of the articles, that is responsive to the search query and is stored in association with a second particular article type that describes a type of the second article,
• where the first particular article type is different from the second particular article type,
• the second article being associated with the second particular article type based on the second article satisfying criteria,
• the second article satisfying the criteria based on a citation score, associated with the second article, being greater than citation scores associated with other articles,
• the citation score indicating a level of citation of the second article or of a source of the second article by one or more other articles about a topic of the second article,
• generate an annotated result based on the first article and the second article,
• where the annotated result comprises:
• a first link to the first article,
• a first visual indicator that identifies the first particular article type,
• a second link to the second article, and
• a second visual indicator that identifies the second particular article type,
• the second particular article type indicating that the second article is cited more than at least one other article about the topic, and
• provide the annotated result for display.
