Abstract

A system may determine a document inception date associated with a document, generate a score for the document based, at least in part, on the document inception date, and rank the document with regard to at least one other document based, at least in part, on the score.

Claims

1. A method implemented by one or more server devices, the method comprising:

determining, by at least one of the one or more server devices, a quantity of links to or from a document;

determining, by at least one of the one or more server devices, an amount of time that has elapsed since an inception date associated with the document;

calculating, by at least one of the one or more server devices, an average rate at which links to or from the document are created based on the quantity of links to or from the document and the amount of time that has elapsed since the inception date associated with the document, calculating the average rate including;

performing a mathematical operation on a first value that is based on the quantity of links to or from the document and a second value that is based on the amount of time that has elapsed since the inception date associated with the document; and

ranking, by at least one of the one or more server devices, the document with regard to at least one other document based on the average rate at which links to or from the document are created.

2. The method of claim 1, further comprising:

providing, for presentation, the document and the at least one other document, based on a search query, in an ordered list, where an order, of the document and the at least one other document within the ordered list, is based on the ranking.

3. The method of claim 1, where the inception date is a date on which a search engine first identifies or indexes the document.

4. The method of claim 1, where the inception date is a date on which a search engine first identifies a link to the document.

5. The method of claim 1, where the inception date is a date on which a domain associated with the document is registered.

6. The method of claim 1, where the inception date is a date on which the document is first referenced in another document.

7. The method of claim 1, where the inception date is a date on which the document includes at least a threshold number of pages.

8. The method of claim 1, where the mathematical operation is a division operation.

9. A non-transitory computer-readable medium storing instructions, the instructions comprising:

a plurality of instructions, which, when executed by one or more processors, cause the one or more processors to;

determine a quantity of links to or from a document;

determine an amount of time that has elapsed since an inception date associated with the document;

calculate an average rate at which links to or from the document are created, based on;

the quantity of links to or from the document, and

the amount of time that has elapsed since the inception date associated with the document, the instructions to calculate the average rate including;

instructions to perform a mathematical operation on a first value that is based on the quantity of links to or from the document and a second value that is based on the amount of time that has elapsed since the inception date associated with the document; and

rank the document with regard to at least one other document based on the average rate at which links to or from the document are created.

10. The computer-readable medium of claim 9, where the inception date is a date on which a search engine first identifies or indexes the document.

11. The computer-readable medium of claim 9, where the inception date is a date on which a search engine first identifies a link to the document.

12. The computer-readable medium of claim 9, where the inception date is a date on which a domain associated with the document is registered.

13. The computer-readable medium of claim 9, where the inception date is a date on which the document is first referenced in another document.

14. The computer-readable medium of claim 9, where the inception date is a date on which the document includes at least a threshold number of pages.

15. The computer-readable medium of claim 9, where the instructions further comprise:

one or more instructions to provide, for presentation, information regarding the document and the at least one other document, based on a search query, in an ordered list, where an order, of the document and the at least one other document within the ordered list, is based on the ranking.

16. A system comprising:

one or more devices to;

determine a quantity of links to or from a document;

determine an amount of time that has elapsed since an inception date associated with the document;

calculate an average rate at which links to or from the document are created, the average rate being derived from;

the quantity of links to or from the document, and

the amount of time that has elapsed since the inception date associated with the document, the one or more devices, when calculating the average rate, being to;

perform a mathematical operation on a first value that is based on the quantity of links to or from the document and a second value that is based on the amount of time that has elapsed since the inception date associated with the document; and

rank the document with regard to at least one other document based on the average rate at which links to or from the document are created.

17. The system of claim 16, where the inception date is a date on which a search engine first identifies or indexes the document.

18. The system of claim 16, where the inception date is a date on which a search engine first identifies a link to the document.

19. The system of claim 16, where the inception date is a date on which a domain associated with the document is registered.

20. The system of claim 16, where the inception date is a date on which the document is first referenced in another document.

21. The system of claim 16, where the inception date is a date on which the document includes at least a threshold number of pages.

22. The system of claim 16, where the one or more devices are further to:

provide, for presentation, information regarding the document and the at least one other document, based on a search query, in an ordered list, where an order, of the document and the at least one other document within the ordered list, is based on the ranking.
