Abstract

A method for providing rated hypermedia content, in which the rating represents degrees of objectionable content, includes four steps: generating raw hypermedia content from a set of units containing data from external data files, obtaining content rating vectors associated with the external data files, deriving a composite content rating vector for the raw hypermedia content from the content rating vectors, and storing the composite content rating vector in the raw hypermedia content to produce rated hypermedia content. Preferably, the raw hypermedia content is a raw search result page created automatically by a search engine in response to a query from a client machine. A rated search result page is generated and transmitted to the client machine over a computer network. The units may represent external data files, preferably other Web pages, and the content rating vectors represent the degrees of objectionable content of the Web pages. Content rating vectors are obtained directly from the external data files or by rating them automatically. The external data files may be of any type, including audio, text, image, or a combination. The composite content rating vector comprises a set of components, and each component is derived from corresponding components of the content rating vectors. Each component may equal the maximum value of the corresponding components of the content rating vectors.

Claims

1. A computer-implemented method for providing an automatically rated search result page to a client machine, said method comprising the steps of:

a) automatically generating a raw search result page from a search query of said client machine, wherein said raw search result page comprises a set of units;

b) obtaining content rating vectors associated with said units, wherein said content rating vectors represent degrees of objectionable content;

c) deriving a composite content rating vector for said raw search result page from said content rating vectors;

d) storing said composite content rating vector in said raw search result page to produce said rated search result page; and

e) transmitting said rated search result page over a computer network to said client machine.

2. The computer-implemented method of claim 1, wherein said units represent data files, and said content rating vectors represent degrees to which said data files are objectionable.

3. The computer-implemented method of claim 2, wherein said data files are selected from the group consisting of text, audio, and image files.

4. The computer-implemented method of claim 2, wherein said content rating vectors are obtained from said data files.

5. The computer-implemented method of claim 2, wherein said content rating vectors are obtained by automatically rating said data files for objectionable content.

6. The computer-implemented method of claim 1, wherein said composite content rating vector comprises a set of components, wherein each component in said set of components is derived from corresponding components of said content rating vectors.

7. The computer-implemented method of claim 6, wherein each component of said composite content rating vector is equal to a maximum value of said corresponding components of said content rating vectors.

8. A computer-implemented method for providing automatically rated hypermedia content, said method comprising thc steps of:

a) automatically generating raw hypermedia content from a set of units, wherein said units contain data from a set of external data files;

b) obtaining content rating vectors associated with said external data files, wherein said content rating vectors represent degrees to which said external data files are objectionable;

c) deriving a composite content rating vector for said raw hypermedia content from said content rating vectors; and

d) storing said composite content rating vector in said raw hypermedia content to produce said rated hypermedia content.

9. The computer-implemented method of claim 8, wherein said external data files are files selected from the group consisting of text, audio, and image.

10. The computer-implemented method of claim 8, wherein said content rating vectors are obtained from said external data files.

11. The computer-implemented method of claim 8, wherein said content rating vectors are obtained by automatically rating said external data files for objectionable content.

12. The computer-implemented method of claim 8, wherein said composite content rating vector comprises a set of components, wherein each component in said set of components is derived from corresponding components of said content rating vectors.

13. The computer-implemented method of claim 12, wherein each component of said composite content rating vector is equal to a maximum value of said corresponding components of said content rating vectors.
