Abstract

Annotations can be handled by a computer system that receives a query that specifies parameters for extraction of particular annotations from a set of annotations. Annotations include metadata that describes properties of the associated text fragment. A first entity subset, a second entity subset and a relations subset of annotations are extracted from an annotated text corpus. Contextual information relative to the extracted annotations is also extracted from the corpus. A user interface is generated to display frame elements that include the extracted annotations subsets and the extracted contextual information. In response to selections to the frame elements, the system receives input that specifies modifications to the annotations. Based on the input received, the set of annotations is modified in the annotated text corpus.

Claims

1. A computer system for modifying a set of annotations that include metadata describing properties of associated text fragments within an annotated text corpus, comprising:

at least one processor circuit having;

an extracting engine configured to;

receive a query specifying parameters for annotations from the set of the annotations;

extract, from the set of annotations and by the query, a first entity subset of annotations, a second entity subset of annotations, and a relations subset of annotations between the first entity subset of annotations and the second entity subset of annotations; and

extract, from the annotated text corpus, contextual information relative to the extracted annotations, wherein each annotation in the first and second entity subset of annotations serves as an anchor for each respective relations subset annotation and each piece of contextual information;

a processing engine configured to;

generate a user interface having display frames populated by frame elements that include the entity subsets of annotations, the relations subset of annotations, and the contextual information; and

receive, responsive to selections of the frame elements, input specifying modifications to the annotations;

an updating engine configured to;

modify, based on the input specifying modifications to the annotations, the set of annotations in the annotated text corpus;

and the processing engine further configured to;

receive additional input specifying a change to the particular annotation label; and

receive additional input specifying a subset of the plurality of annotations; and

the updating engine further configured to;

modify, based on the additional input, the particular annotation label for each of the annotations in the subset of the plurality of annotations having the shared particular annotation label.

2. The computer system of claim 1, wherein the set of annotations includes a plurality of annotations having a shared particular annotation label, and wherein the system comprises:

at least one computer processor circuit having;

a processing engine configured to;

receive additional input specifying a change to the particular annotation label; and

an updating engine configured to;

modify, based on the additional input, the particular annotation label for each of the annotations in the plurality of annotations having the particular annotation label.

3. The computer system of claim 1, wherein the extracting engine is configured to extract, from the set of annotations and by the query, by:

filtering, responsive to first entity parameters specified in the query, the set of annotations for the first entity subset of annotations;

filtering, responsive to second entity parameters specified in the query, the set of annotations for the second entity subset of annotations; and

filtering, responsive to parameters specified in the query, the set of annotations for the relations subset of annotations.

4. The computer system of claim 1, wherein the processing engine is further configured to generate a user interface that displays a frame that contains a particular document name in the annotated text corpus, the system comprising:

at least one computer processor circuit having;

a processing engine configured to;

receive input that specifies the particular document name in the annotated text corpus; and

generate, responsive to the input that specifies the particular document name, a frame containing data from the particular document named.

5. The computer system of claim 4 comprising:

at least one computer processor circuit having;

a processing engine configured to;

receive input from the frame containing data from the particular document; and

modify, responsive to the input from the frame containing data from the particular document, annotations of the particular document in the annotated text corpus.

6. A computer program product for modifying a set of annotations that include metadata describing properties of associated text fragments within an annotated text corpus, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions executable by a computer processing circuit to cause the circuit to perform the method comprising:

receiving a query specifying parameters for annotations from the set of the annotations;

extracting, from the set of annotations and by the query, a first entity subset of annotations, a second entity subset of annotations, and a relations subset of annotations between the first entity subset of annotations and the second entity subset of annotations, wherein each annotation in the first and second entity subset of annotations serves as an anchor for each respective relations subset annotation and each piece of contextual information;

extracting, from the annotated text corpus, contextual information relative to the extracted annotations;

generating a user interface having display frames populated by frame elements that include the entity subsets of annotations, the relations subset of annotations, and the contextual information;

receiving, responsive to selections of the frame elements, input specifying modifications to the annotations;

modifying, based on the input specifying modifications to the annotations, the set of annotations in the annotated text corpus;

receiving additional input specifying a change to the particular annotation label;

receiving additional input specifying a subset of the plurality of annotations; and

modifying, based on the additional input, the particular annotation label for each of the annotations in the subset of the plurality of annotations having the shared particular annotation label.

7. The computer program product of claim 6, wherein the set of annotations includes a plurality of annotations having a shared particular annotation label, and wherein the method comprises:

receiving additional input specifying a change to the particular annotation label; and

modifying, based on the additional input, the particular annotation label for each of the annotations in the plurality of annotations having the particular annotation label.

8. The computer program product of claim 6, wherein the extracting, from the set of annotations and by the query, further comprises:

filtering, responsive to first entity parameters specified in the query, the set of annotations for the first entity subset of annotations;

filtering, responsive to second entity parameters specified in the query, the set of annotations for the second entity subset of annotations; and

filtering, responsive to parameters specified in the query, the set of annotations for the relations subset of annotations.

9. The computer program product of claim 6, wherein the user interface includes a frame containing a particular document name in the annotated text corpus, wherein the method comprises:

receiving input that specifies the particular document name in the annotated text corpus; and

generating, responsive to the input that specifies the particular document name, a frame containing data from the particular document named.

10. The computer program product of claim 9, wherein the method comprises:

receiving input from the frame containing data from the particular document; and

modifying, responsive to the input from the frame containing data from the particular document, annotations of the particular document in the annotated text corpus.
