Abstract

Determining a relevancy ranking score is disclosed. A query is received that includes one or more constraints. One of the one or more constraints includes an operator. A search result based on the query is received. The relevancy ranking score for the received search result is determined based at least in part on the operator associated with the one or more constraints of the query.

Claims

1. A method of determining a relevancy ranking score, comprising:

receiving a query including one or more constraints, wherein one of the one or more constraints includes an operator, wherein the operator comprises one or more of the following;

CONTAINS, DOES_NOT_CONTAIN, BEGINS_WITH, ENDS_WITH, ALWAYS_WITHIN, AND, OR, NOT, EQUALS, NOT_EQUALS, GREATER_THAN, LESS_THAN, GREATER_THAN_OR_EQUAL_TO, LESS_THAN_OR_EQUAL_TO;

receiving a search result based on the query; and

determining, using a processor, the relevancy ranking score for the received search result based at least in part on the operator associated with the one or more constraints of the query, wherein the relevancy ranking score comprises a sum of three or more feature scores each multiplied by a separate weight, wherein the three or more feature scores comprise a scope or depth score, an accuracy or validity score, a clarity score, a currency score, or a source score, and wherein the scope or depth score comprises a score indicating satisfied constraints, and wherein the accuracy or validity score comprises a score indicating constraints improving query precision, and wherein the clarity score comprises a score indicating information presented in a clear manner, and wherein the currency score comprises a score indicating more recent results, and wherein the source score comprises a score indicating source quality, wherein presented in the clear manner for the clarity score comprises having a higher score in an event in which a title, an abstract, or a date is present.

2. A method as in claim 1, wherein the search result is one of a plurality of search results and wherein the plurality of search results are from a plurality of search sources.

3. A method as in claim 1, wherein the search result includes a ranking from a search source.

4. A method as in claim 1, further comprising calculating a relevancy ranking based at least in part on the relevancy ranking score for a plurality of search results resulting from the search query.

5. A method as in claim 1, further comprising calculating a relevancy ranking based at least in part on the relevancy ranking score and based at least in part on a second ranking score for a plurality of search results resulting from the search query.

6. A computer program product for determining a relevancy ranking score, the computer program product being embodied in a computer readable storage medium and comprising computer instructions for:

receiving a query including one or more constraints, wherein one of the one or more constraints includes an operator, wherein the operator comprises one or more of the following;

CONTAINS, DOES_NOT_CONTAIN, BEGINS_WITH, ENDS_WITH, ALWAYS_WITHIN, AND, OR, NOT, EQUALS, NOT_EQUALS, GREATER_THAN, LESS_THAN, GREATER_THAN_OR_EQUAL_TO, LESS_THAN_OR_EQUAL_TO;

receiving a search result based on the query; and

determining the relevancy ranking score for the received search result based at least in part on the operator associated with the one or more constraints of the query, wherein the relevancy ranking score comprises a sum of three or more feature scores each multiplied by a separate weight, wherein the three or more feature scores comprise a scope or depth score, an accuracy or validity score, a clarity score, a currency score, or a source score, and wherein the scope or depth score comprises a score indicating satisfied constraints, and wherein the accuracy or validity score comprises a score indicating constraints improving query precision, and wherein the clarity score comprises a score indicating information presented in a clear manner, and wherein the currency score comprises a score indicating more recent results, and wherein the source score comprises a score indicating source quality, wherein presented in the clear manner for the clarity score comprises having a higher score in an event in which a title, an abstract, or a date is present.

7. The computer program product recited in claim 6, wherein the search result is one of a plurality of search results and wherein the plurality of search results are from a plurality of search sources.

8. The computer program product recited in claim 6, wherein the search result includes a ranking from a search source.

9. The computer program product recited in claim 6, further comprising computer instructions for calculating a relevancy ranking based at least in part on the relevancy ranking score for a plurality of search results resulting from the search query.

10. The computer program product recited in claim 6, further comprising computer instructions for calculating a relevancy ranking based at least in part on the relevancy ranking score and based at least in part on a second ranking score for a plurality of search results resulting from the search query.

11. The computer program product recited in claim 6, further comprising computer instructions for:

receiving a search result based on the query, wherein one or more attributes are synthesized from the search results, wherein the one or more attributes are combined from one or more parts of the search result; and

determining, using a processor, the relevancy ranking score based at least in part on the one or more attributes.

12. The computer program product recited in claim 11, wherein the one or more attributes includes a title.

13. The computer program product recited in claim 11, wherein the one or more attributes includes a date.

14. The computer program product recited in claim 11, wherein the one or more attributes includes an abstract.

15. The computer program product recited in claim 11, wherein the one or more attributes includes a body.

16. A system for determining a relevancy ranking score, comprising:

a processor; and

a memory coupled with the processor, wherein the memory is configured to provide the processor with instructions which when executed cause the processor to;

receive a query including one or more constraints, wherein one of the one or more constraints includes an operator, wherein the operator comprises one or more of the following;

CONTAINS, DOES_NOT_CONTAIN, BEGINS_WITH, ENDS_WITH, ALWAYS_WITHIN, AND, OR, NOT, EQUALS, NOT_EQUALS, GREATER_THAN, LESS_THAN, GREATER_THAN_OR_EQUAL_TO, LESS_THAN_OR_EQUAL_TO;

receive a search result based on the query; and

determine the relevancy ranking score for the received search result based at least in part on the operator associated with the one or more constraints of the query, wherein the relevancy ranking score comprises a sum of three or more feature scores each multiplied by a separate weight, wherein the three or more feature scores comprise a scope or depth score, an accuracy or validity score, a clarity score, a currency score, or a source score, and wherein the scope or depth score comprises a score indicating satisfied constraints, and wherein the accuracy or validity score comprises a score indicating constraints improving query precision, and wherein the clarity score comprises a score indicating information presented in a clear manner, and wherein the currency score comprises a score indicating more recent results, and wherein the source score comprises a score indicating source quality, wherein presented in the clear manner for the clarity score comprises having a higher score in an event in which a title, an abstract, or a date is present.

17. A system as in claim 16, wherein the search result is one of a plurality of search results and wherein the plurality of search results are from a plurality of search sources.
