Abstract

A system includes determination of a name of a semantic object associated with a semantic layer, determination of a linguistic entity category associated with the name, and storage, in association with the semantic layer, of an association between the semantic object and the linguistic entity category. Also included may be determination of a plurality of values associated with the semantic object, and creation of a custom linguistic entity category associated with the semantic object and comprising a plurality of entities, wherein each of the plurality of entities corresponds to a respective one of the plurality of values.

Claims

1. A method comprising:

determining a name of a semantic object associated with a semantic layer;

determining a linguistic entity category associated with the name; and

storing, in association with the semantic layer, an association between the semantic object and the linguistic entity category.

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

stemming the name of the semantic object to generate a stem, and

wherein determining the linguistic entity category comprises determining a linguistic entity category associated with the stem.

3. A method according to claim 1, wherein determining the linguistic entity category comprises determining the linguistic entity category from a plurality of linguistic entity categories comprising:

a Subject Type category, a Dimension Type category, an Analysis Type category and a Dimension category.

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

determining a plurality of values associated with the semantic object; and

creating a custom linguistic entity category associated with the semantic object and comprising a plurality of entities,

wherein each of the plurality of entities corresponds to a respective one of the plurality of values.

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

determining a stem of each of the plurality of values,

wherein a normal form of each of the plurality of entities is the determined stem of its respective one of the plurality of values.

6. A method according to claim 5, further comprising:

determining that a normal form of one of the plurality of entities is a variant of an entity of a linguistic entity category;

determining one or more other variants of the entity of the linguistic entity category; and

associating the one or more variants with the one of the plurality of entities of the custom linguistic entity category.

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

indicating one or more semantic objects for which a custom dimension category will not be generated.

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

receiving a manual indication to associate another semantic object with one or more linguistic entity categories.

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

determine a name of a semantic object associated with a semantic layer;

determine a linguistic entity category associated with the name; and

store, in association with the semantic layer, an association between the semantic object and the linguistic entity category.

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

stem the name of the semantic object to generate a stem, and

wherein determination of the linguistic entity category comprises determination of a linguistic entity category associated with the stem.

11. A computer program product according to claim 9, wherein determination of the linguistic entity category comprises determination of the linguistic entity category from a plurality of linguistic entity categories comprising:

a Subject Type category, a Dimension Type category, an Analysis Type category and a Dimension category.

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

determine a plurality of values associated with the semantic object; and

create a custom linguistic entity category associated with the semantic object and comprising a plurality of entities,

wherein each of the plurality of entities corresponds to a respective one of the plurality of values.

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

determine a stem of each of the plurality of values,

wherein a normal form of each of the plurality of entities is the determined stem of its respective one of the plurality of values.

14. A computer program product according to claim 13, the program code further executable by a computer to:

determine that a normal form of one of the plurality of entities is a variant of an entity of a linguistic entity category;

determine one or more other variants of the entity of the linguistic entity category; and

associate the one or more variants with the one of the plurality of entities of the custom linguistic entity category.

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

indicate one or more semantic objects for which a custom dimension category will not be generated.

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

receive a manual indication to associate another semantic object with one or more linguistic entity categories.

17. A system comprising:

a semantic layer including a plurality of semantic objects;

a pre-processor to determine a name of a semantic object associated with a semantic layer; and

a linguistic processor to determine a linguistic entity category associated with the name,

wherein an association between the semantic object and the linguistic entity category is stored in association with the semantic layer.

18. A system according to claim 17, wherein the linguistic processor is further to:

stem the name of the semantic object to generate a stem, and

determine the linguistic entity category associated with the stem.

19. A system according to claim 17, wherein the linguistic entity category is determined from a plurality of linguistic entity categories comprising:

a Subject Type category, a Dimension Type category, an Analysis Type category and a Dimension category.

20. A system according to claim 17, the pre-processor further to:

determine a plurality of values associated with the semantic object; and

create a custom linguistic entity category associated with the semantic object and comprising a plurality of entities,

wherein each of the plurality of entities corresponds to a respective one of the plurality of values.

21. A system according to claim 20, wherein the linguistic processor is further to:

determine a stem of each of the plurality of values,

wherein a normal form of each of the plurality of entities is the determined stem of its respective one of the plurality of values.

22. A system according to claim 21, wherein the linguistic processor is further to:

determine that a normal form of one of the plurality of entities is a variant of an entity of a linguistic entity category; and

determine one or more other variants of the entity of the linguistic entity category; and

wherein the pre-processor is further to;

associate the one or more variants with the one of the plurality of entities of the custom linguistic entity category.
