Abstract

A user inputs to a document retrieving apparatus a retrieval string whose priority level is represented by using multiple of highlight levels, such as a degree of a font size and the like. A document retrieving apparatus retrieves a document including the retrieval string from a database and displays the retrieval string included in the retrieval result on a screen at the same highlight level as that at a time of inputting. In this way, the strings having different priority levels within the document are displayed at highlight levels different from each other. It is possible to specify a new retrieval string within the document of the retrieval result to thereby carry out a re-retrieval.

Claims

1. A document retrieving apparatus for use in an information processing system for retrieving a document from a text database with a specified string as a retrieval key, comprising:

input means for visually highlighting and inputting at least one retrieval string at a highlighting level;

retrieving means for retrieving a document including said at least one highlighted and inputted retrieval string; and

output means for highlighting said at least one retrieval string included in the retrieved document at a highlighting level corresponding to the highlighting level at a time of inputting, and for outputting at least one highlighted retrieval string.

2. A document retrieving apparatus according to claim 1, wherein said output means outputs said highlighted retrieval string at the highlight level specified at the time of inputting.

3. A document retrieving apparatus according to claim 1, wherein said input means comprises a display means for displaying said inputted retrieval string and a pointing means for specifying the appropriate retrieval string displayed by said display means to thereby change the highlight level of the at least one retrieval string.

4. A document retrieving apparatus according to claim 3, wherein said pointing means comprises an operating means for specifying a size of said at least one retrieval string as said highlight level.

5. A document retrieving apparatus for use in an information processing system for retrieving a document from a text database with a specified string as a retrieval key, comprising:

input means for visually highlighting and inputting at least one retrieval string at a highlighting level;

retrieving means for retrieving a document including said at least one highlighted and inputted retrieval string; and

relevance level judging means for making the highlighting level of said at least one retrieval string included in the retrieved document correspond to a priority level, and for judging a relation between the at least one retrieval string and the retrieved document using the priority level.

6. A document retrieving apparatus according to claim 5, wherein said relevance level judging means converts the highlight level of said at least one retrieval string into said priority level, uses the priority level to thereby calculate a relevance level of said retrieved document, and preferentially defines a document having a high relevance level as a retrieval result.

7. A document retrieving apparatus for use in an information processing system for retrieving a document from a text database with a specified string as a retrieval key, a document retrieving apparatus comprising:

input means for inputting at least one retrieval string;

retrieving means for retrieving a document including said at least one inputted retrieval string;

output means for outputting a retrieval result; and

feedback means for feeding back highlighting level information specified in said outputted retrieval result to said input means so as to retrieve the document again.

8. A document retrieving apparatus according to claim 7, wherein said feedback means comprises a pointing means for specifying any portion of said outputted retrieval result and feeds back a string specified by said pointing means, as a new retrieval string, to said input means.

9. A document retrieving apparatus according to claim 7, wherein said feedback means comprises a pointing means for specifying said at least one retrieval string included in said outputted retrieval result to thereby change the highlight level of said at least one retrieval string and feeds back a highlight level specified by said pointing means to said input means.

10. A document retrieving apparatus according to claim 9, wherein said pointing means comprises an operating means for specifying a size of said at least one retrieval string as said highlight level.

11. A document retrieving apparatus according to claim 7, wherein said input means inputs a new retrieval string based on the information fed back by said feedback means, said retrieving means again retrieves a document including the new retrieval string and said output means outputs a result of the re-retrieval.

12. A document retrieving apparatus according to claim 7, further comprising a relevance level judging means for judging, from a priority level of said at least one retrieval string included in the retrieved document, a relation between the retrieval string and the retrieved document, wherein

said output means outputs said retrieval result on the basis of the judgment of the relevance level judging means,

said feedback means changes the priority level of the at least one retrieval string to thereby feed back to said input means,

said input means inputs a changed priority level, and

said relevance level judging means again judges said relation from the changed priority level.

13. A document output apparatus for use in an information processing system, comprising:

input means for inputting at least one string, and

output means for highlighting said at least one string by using one of a plurality of highlight levels prepared in advance and for outputting a document including said at least one string.

14. A computer-readable recording medium, when used by a computer which retrieves a document from a text database with a specified string as a retrieval key, used to direct the computer to perform the functions of:

visually highlighting and inputting at least one retrieval string at a highlighting level;

retrieving a document including said at least one highlighted and inputted retrieval string; and

highlighting said at least one retrieval string included in the retrieved document at a highlighting level corresponding to the highlighting level at a time of inputting, and for outputting at least one highlighted retrieval string.

15. A computer-readable recording medium, when used by a computer which retrieves a document from a text database with a specified string as a retrieval key, used to direct the computer to perform the functions of:

visually highlighting and inputting at least one retrieval string at a highlighting level;

retrieving a document including said at least one highlighted and inputted retrieval string; and

making the highlighting level of said at least one retrieval string included in the retrieved document correspond to a priority level, and for judging a relevance between the at least one retrieval string and the retrieved document using the priority level.

16. A computer-readable recording medium, when used by a computer which retrieves a document from a text database with a specified string as a retrieval key, used to direct the computer to perform the functions of:

inputting at least one retrieval string;

retrieving a document including said at least one inputted retrieval string;

outputting the retrieval result; and

using highlighting level information specified in said outputted retrieval result to thereby retrieve the document again.

17. A computer-readable recording medium, when used by a computer, used to direct the computer to perform the functions of:

visually highlighting and inputting at least one string;

highlighting said at least one string by using one of a plurality of highlight levels prepared in advance; and
