Abstract

A system includes a memory operable to store a search index. The system also includes a processor communicatively coupled to the memory. The processor is operable to receive a search request relating to information stored in an ontology. The processor is further operable to parse the search request to determine a search type. The processor is further operable to query, based at least in part on the search type, one or more of the search index and the ontology.

Claims

1. A system, comprising:

a memory operable to store a search index associated with an ontology, wherein the ontology comprises at least one instance and the instance has a name; and

a processor communicatively coupled to the memory and operable to;

query the search index and the ontology in parallel, wherein the search index is generated based at least in part upon an unstructured data element by streaming and normalizing received data terms from a data source and the ontology is generated based at least in part upon an structured data element at least one data mitigation and classification rule;

receive a first search request relating to information stored in an ontology;

parse the first search request to determine if the first search request is an instance based search that comprises all or part of a name of at least a first instance in the ontology;

perform a first query of the search index in response to determining that the first search request is an instance based search;

receive a second search request relating to information stored in the ontology;

parse the second search request to determine if the second search request is an instance based search that comprises all or part of a name of at least a second instance in the ontology; and

perform a second query of at least the ontology in response to determining that the second search request is not an instance based search

receive a third search request relating to information not stored in the ontology;

parse the third search request to determine that the third search request is an instance based search that comprises all or part of a name of at least one instance in the ontology;

perform a third query of the search index and retrieve metadata associated with the third instance from the search index, wherein the metadata comprises information about a data source associated with the third instance; and

retrieve information from the data source that are not stored in the ontology.

2. The system of claim 1, wherein performing either the first query or the second query further comprises identifying a symbol in the search index based on the search request, wherein the symbol corresponds to a particular instance in the ontology.

3. The system of claim 1, wherein performing the first query or the second query further comprises identifying one or more instances in the ontology based on the search request.

4. The system of claim 1, wherein performing the first query or the second query further comprises:

identifying a symbol in the search index based on the search request, wherein the symbol corresponds to a particular instance in the ontology;

submitting a query to the ontology based on the symbol;

receiving, in response to either query, one or more instances from the ontology, wherein the one or more instances are related to the particular instance in the ontology.

5. The system of claim 1, wherein the processor is further operable to generate the search index at least in part by indexing data stored in the ontology.

6. The system of claim 1, wherein the processor is further operable to:

receive a plurality of terms, the terms having been generated by processing unstructured data from a data source; and

generate the search index at least in part by indexing the plurality of terms.

7. A method, comprising:

receiving a first search request relating to information stored in an ontology, wherein the ontology comprises at least one instance and the instance has a name;

parsing the first search request to determine if the first search request is an instance based search that comprises all or part of a name of at least a first instance in the ontology;

performing a first query of a search index associated with the ontology in response to determining that the first search request is an instance based search;

receiving a second search request relating to information stored in the ontology;

parsing the second search request to determine if the second search request is an instance based search that comprises all or part of a name of at least a second instance in the ontology; and

performing a second query of at least the ontology in response to determining that the second search request is not an instance based search;

receiving a third search request relating to information not stored in the ontology;

parsing the third search request to determine that the third search request is an instance based search that comprises all or part of a name of at least a third instance in the ontology;

performing a third query of the search index and retrieving metadata associated with the third instance from the search index, wherein the metadata comprises information about a data source associated with the third instance;

retrieving information from the data source that are not stored in the ontology; and

wherein the search index and the ontology queried in parallel, wherein the search index is generated based at least in part upon an unstructured data element by streaming and normalizing received data terms from the data source and the ontology is generated based at least in part upon an structured data element at least one data mitigation and classification rule.

8. The method of claim 7, wherein performing either the first query or the second query further comprises identifying a symbol in the search index based on the search request, wherein the symbol corresponds to a particular instance in the ontology.

9. The method of claim 7, wherein performing either the first query or the second query further comprises identifying one or more instances in the ontology based on the search request.

10. The method of claim 7, wherein performing either the first query or the second query further comprises:

identifying a symbol in the search index based on the search request, wherein the symbol corresponds to a particular instance in the ontology;

submitting a query to the ontology based on the symbol; and

receiving, in response to either query, one or more instances from the ontology, wherein the one or more instances are related to the particular instance in the ontology.

11. The method of claim 7, further comprising generating the search index at least in part by indexing data stored in the ontology.

12. The method of claim 7, further comprising:

receiving a plurality of terms generated by processing unstructured data from a data source; and

generating the search index at least in part by indexing the plurality of terms.

13. One or more non-transitory storage media embodying logic that is operable when executed by one or more processors to:

query the search index and the ontology in parallel, wherein the search index is generated based at least in part upon an unstructured data element by streaming and normalizing received data terms from a data source and the ontology is generated based at least in part upon an structured data element at least one data mitigation and classification rule;

receive a first search request relating to information stored in the ontology, wherein the ontology comprises at least one instance and the instance has a name;

parse the first search request to determine if the first search request is an instance based search that comprises all or part of a name of at least a first instance in the ontology;

perform a first query of the search index associated with the ontology in response to determining that the first search request is an instance based search;

receive a second search request relating to information stored in an ontology;

parse the second search request to determine if the second search request is an instance based search that comprises all or part of a name of at least a second instance in the ontology; and

perform a second query of at least the ontology in response to determining that the second search request is not an instance based search;

receive a third search request relating to information not stored in the ontology;

parse the third search request to determine that the third search request is an instance based search that comprises all or part of a name of at least a third instance in the ontology;

perform a third query of the search index and retrieve metadata associated with the third instance from the search index, wherein the metadata comprises information about a data source associated with the third instance; and

retrieve information from the data source that are not stored in the ontology.

14. The storage media of claim 13, wherein performing either the first query or the second query further comprises identifying a symbol in the search index based on the search request, wherein the symbol corresponds to a particular instance in the ontology.
