Abstract

An assignment device (1) assigns word class information (WKI) to one or more words of text information (ETI). Based on word-class sequence information (WK-AI) formed from this assigned word class information (WKI), actions (A) are executed in order to notify the user of conflicts or to provide the user with background information (HI) relating to words in the text information (TT).

Claims

1. An assignment device (1) with

assignment means (4) for assigning supplementary information to one or more words of text information (ETI),

characterized in that

the assignment means (4) is designed to assign word class information (WKI) to one or more words of text information (ETI), and to deliver word-class sequence information (WK-AI) containing the assigned word-class information (WKI), and that linkage means (7) designed to detect the presence of at least two specific items of word-class information (WKI) in the word-class sequence information (WK-AI) and to deliver the corresponding linkage information (VI) is provided, and that

action means (10) designed to activate an action (A) when specific linkage information (VI) or a specific combination of linkage information (VI) is delivered by the linkage means (7) is provided.

2. An assignment device (1) as claimed in claim 1, characterized in that the linkage means (7) is designed to deliver the linkage information (VI) only when the presence of at least two items of word-class information (WKI) is detected within a maximum word-class distance.

3. An assignment device (1) as claimed in claim 1, characterized in that word memory means (5) is provided, with which words and associated word class information (WKI) are stored, and that the assignment means (4) is designed to establish the word class information (WKI) to be assigned to a word for reading from word memory means (5).

4. An assignment device (1) as claimed in claim 1, characterized in that the assignment means (4) is part of a voice recognition device (3) and is designed to assign word class information (WKI) to one or more words of the text information (ETI) recognized by voice recognition means (3).

5. An assignment device (1) as claimed in claim 1, characterized in that the action means (10) is designed to activate an acoustic and/or visual notification (AI2, DI) as action (A).

6. An assignment device (1) as claimed in claim 1, characterized in that both the specific word class information (WKI) to be detected by the linkage means (7) in the word class sequence information (WK-AI) and the actions (A) to be activated by action means (10) can be manually adjusted.

7. An assignment device (1) as claimed in claim 1, characterized in that the action means (10) is designed to establish and to deliver background information (HI) as supplementary information assigned to the text information (ETI) if specific linkage information (VI) assigned to specific words of the text information (ETI) is present, wherein words to which supplementary information is assigned can be displayed with special marking.

8. An assignment device (1) as claimed in claim 1, characterized in that, in order to assign word class information (WKI), the assignment means (4) firstly establishes the wordstem relating to the word or words of text information (ETI).

14. A computer program product, which can be loaded directly into the internal memory of a digital computer and which comprises sections of software code, wherein the steps of the assignment method as claimed in claim 8 are implemented with the computer when the product is running on the computer.

15. A computer program product as claimed in claim 14, wherein it is stored on a computer-readable medium.

9. An assignment method for assigning supplementary information to one or more words of text information (ETI), wherein the following steps are implemented:

assignment of word-class information (WKI) to one or more words of text information (ETI);

delivery of word-class sequence information (WK-AI) containing the assigned word-class information (WKI);

detection of the presence of at least two specific items of word-class information (WKI) in the word-class sequence information (WK-AI);

delivery of linkage information (VI) identifying the detected word-class information (WKI);

activation of an action (A) when specific linkage information (VI) or a specific combination of linkage information (VI) is delivered.

10. An assignment method as claimed in claim 9, characterized in that the linkage information (VI) is delivered only if the presence of at least two items of word-class information (WKI) is detected within a maximum word class distance.

11. An assignment method as claimed in claim 9, characterized in that the assignment method is applied to an item of text information (ETI) recognized using a voice recognition method, wherein supplementary text information (TZI) established with the voice recognition method and relating to the recognized text information (ETI) is used in the assignment method.

12. An assignment method as claimed in claim 9, characterized in that an acoustic and/or visual notification (AI2, DI) is delivered as the action.

13. An assignment method as claimed in claim 9, characterized in that, if specific linkage information (VI) assigned to specific words of text information (ETI) is present, the background information (HI) read from the background dictionary (12) relating to these words is established and delivered as supplementary information, wherein words to which supplementary information is assigned are displayed with special marking.
