Abstract

A blog search engine may receive a search query. The blog search engine may determine scores for a group of blog documents in response to the search query, where the scores are based on a relevance of the group of blog documents to the search query and a quality of the group of blog documents. The blog search engine may also provide information regarding the group of blog documents based on the determined scores.

Claims

1. A method comprising:

receiving a search query by a blog search engine;

retrieving a blog document in response to the search query;

determining a first score for the blog document based on the relevance of the blog document to the search query;

altering the first score based on a quality of the blog document; and

providing information regarding the blog document based on the altered first score.

2. The method of claim 1 wherein the blog document includes a blog or a blog post.

3. The method of claim 1 further comprising:

determining the quality of the blog document based on a plurality of indicators.

4. The method of claim 3 wherein the plurality of indicators includes at least one of one or more positive indicators or one or more negative indicators.

5. The method of claim 4 wherein the one or more positive indicators include one or more of a popularity of the blog document, an existence of a link to the blog document in one or more blogrolls associated with other blog documents, tagging of the blog document, a reference to the blog document in other documents, or a pagerank of the blog document, and

wherein the one or more negative indicators include one or more of a frequency with which posts are added to the blog document, a content of the blog document, a size of posts in the blog document, a link distribution associated with the blog document, a quantity of ads in the blog document, or a location of ads in the blog document.

6. The method of claim 4 wherein the determining the quality of the blog document includes:

combining the one or more positive indicators and the one or more negative indicators to determine a quality score for the blog document.

7. The method of claim 6 wherein the altering the first score includes:

increasing or decreasing the first score based on the quality score.

8. The method of claim 1 wherein the quality of the blog document is unrelated to the search query.

9. A system comprising:

means for receiving a search query by a blog search engine;

means for obtaining a blog document in response to the search query;

means for determining a first score for the blog document based on the relevance of the blog document to the search query;

means for adjusting the first score based on a quality of the blog document; and

means for providing information relating to the blog document based on the adjusted first score.

10. A device comprising:

a blog search engine to;

receive a search query;

retrieve a plurality of blog documents in response to the search query;

determine a first score for each blog document in the plurality of blog documents based on the relevance of the each blog document to the search query;

alter the first score of each blog document based on a quality of the each blog document; and

provide information regarding the blog documents based on the altered first scores.

11. A computer-readable medium containing instructions for controlling a processor to perform a method comprising:

receiving a search query by a blog search engine;

retrieving documents in response to the search query, the documents including a blog document;

determining scores for the documents based on the relevance of the documents to the search query;

altering the score of the blog document based on a quality of the blog document; and

providing information regarding the documents based on the determined scores and altered score.

12. A computer-implemented method comprising:

obtaining a blog document;

identifying at least one of positive indictors of a quality of the blog document or negative indicators of the quality of the blog document; and

determining a quality score for the blog document based on the identified at least one of positive indicators or negative indicators.
