Abstract

A system includes reception of text, extraction of a plurality of linguistic entities and associated linguistic entity categories based on the text; determination of one or more semantic objects of a semantic layer based on the linguistic entity categories, and generation of a query of the semantic layer based on the plurality of linguistic entities, the associated linguistic entity categories, and the one or more semantic objects. In some aspects, extraction of the plurality of linguistic entities includes identification of the plurality of linguistic entities from a plurality of semantic object-independent linguistic entity categories and a plurality of semantic object-dependent linguistic entity categories, wherein the plurality of semantic object-dependent linguistic entity categories are associated with the semantic layer, and wherein each of the plurality of semantic object-dependent linguistic entity categories is associated with a respective semantic object of the semantic layer and each entity of each semantic object-dependent linguistic entity category is associated with a value of its respective semantic object.

Claims

1. A method comprising:

receiving text;

extracting a plurality of linguistic entities and associated linguistic entity categories based on the text;

determining one or more semantic objects of a semantic layer based on the linguistic entity categories; and

generating a query of the semantic layer based on the plurality of linguistic entities, the associated linguistic entity categories, and the one or more semantic objects.

2. A method according to claim 1, wherein extracting the plurality of linguistic entities comprises:

identifying the plurality of linguistic entities from a plurality of semantic object-independent linguistic entity categories and a plurality of semantic object-dependent linguistic entity categories,

wherein the plurality of semantic object-dependent linguistic entity categories are associated with the semantic layer, and

wherein each of the plurality of semantic object-dependent linguistic entity categories is associated with a respective semantic object of the semantic layer and each entity of each semantic object-dependent linguistic entity category is associated with a value of its respective semantic object.

3. A method according to claim 1, further comprising:

determining an analysis context based on the text, the linguistic entities, and the associated linguistic entity category,

wherein generating the query of the semantic layer comprises generating the query based on the analysis context and the one or more semantic objects.

4. A method according to claim 3, further comprising:

identifying two or more phrases from the text,

wherein determining an analysis context comprises;

for each of the two or more phrases, identifying an associated linguistic entity.

5. A method according to claim 4, wherein extracting the associated linguistic entity comprises:

identifying the associated linguistic entity category from a plurality of semantic object-independent linguistic entity categories and a plurality of semantic object-dependent linguistic entity categories,

wherein the plurality of semantic object-dependent linguistic entity categories are associated with the semantic layer, and

wherein each of the plurality of semantic object-dependent linguistic entity categories is associated with a respective semantic object of the semantic layer and each entity of each semantic object-dependent linguistic entity category is associated with a value of its respective semantic object.

6. A method according to claim 3, wherein generating the query of the semantic layer comprises:

generating the query based on the analysis context; and

generating a second query based on the analysis context.

7. A method according to claim 1, further comprising:

receiving query results associated with the query; and

determining a visualization based on the query results and on one or more of the associated linguistic entity categories.

8. A method according to claim 7, further comprising:

determining the visualization based on an Analysis Type category associated with the query.

9. A computer-readable medium having stored thereon program code, the program code executable by a computer to:

receive text;

extract a plurality of linguistic entities and associated linguistic entity categories based on the text;

determine one or more semantic objects of a semantic layer based on the linguistic entity categories; and

generate a query of the semantic layer based on the plurality of linguistic entities, the associated linguistic entity categories, and the one or more semantic objects.

10. A medium according to claim 9, wherein the program code executable by a computer to extract the plurality of linguistic entities comprises program code executable by a computer to:

identify the plurality of linguistic entities from a plurality of semantic object-independent linguistic entity categories and a plurality of semantic object-dependent linguistic entity categories,

wherein the plurality of semantic object-dependent linguistic entity categories are associated with the semantic layer, and

wherein each of the plurality of semantic object-dependent linguistic entity categories is associated with a respective semantic object of the semantic layer and each entity of each semantic object-dependent linguistic entity category is associated with a value of its respective semantic object.

11. A medium according to claim 9, the program code further executable by a computer to:

determine an analysis context based on the text, the linguistic entities, and the associated linguistic entity category,

wherein generation of the query of the semantic layer comprises generation of the query based on the analysis context and the one or more semantic objects.

12. A medium according to claim 11, the program code further executable by a computer to:

identify two or more phrases from the text,

wherein determination of an analysis context comprises;

for each of the two or more phrases, identification of an associated linguistic entity.

13. A medium according to claim 12, wherein the program code executable by a computer to extract the associated linguistic entity comprises program code executable by a computer to:
