Abstract

Disclosed herein are systems, methods and products for interpreting and structuring free text records utilizing extractions of several types including syntactic, role, thematic and domain extractions. Also disclosed herein are systems, methods and products for integrating interpretive extractions with structured data into unified structures that can be analyzed with, among other tools, data mining and data visualization tools.

Claims

1. A system for providing a service to identify and structure free text databases, comprising:

a processing element;

one or more data access ports, said ports providing access to data by said processing element;

a set of one or more input devices readable by said processing element;

a storage device, said storage device containing instructions executable by said processing element to perform the functions of;

(i) reading an access reference through said input device set, the access reference referencing a customer'"'"'s source of unstructured data, the unstructured data including free text;

(ii) accessing the source of unstructured data;

(iii) identifying text records within the free text;

(iv) linguistically parsing the identified text records;

(v) identifying roles within the parsed text records, said identifying producing attribute extractions, each of said attribute extractions containing attribute information of the derived source text;

(v) applying caseframes to the attribute extractions, said applying caseframes producing a filtered set of attributes extractions; and

(vi) producing a structured data element containing the filtered set of extractions.

2. A system according to claim 1, wherein said instructions are further executable to perform the function of identifying domains of the filtered set of attributes extractions.

3. A system according to claim 2, wherein said instructions are further executable to perform the function of the assignment of domain roles.

4. A system according to claim 3, wherein said instructions are further executable to perform the function of producing relation types.

5. A system according to claim 4, wherein said instructions are further executable to perform the function of coalescing the produced relation types.

6. A system according to claim 1, wherein said instructions are further executable to perform the function of creating a new database containing the structured data element produced in said producing.

7. A system according to claim 1, wherein the instructions are further executable to produce a new relational database containing the structured data element produced in said producing a structured data element.

8. A system according to claim 1, wherein said instructions are further executable to perform the function of producing a file containing the structured data element produced in said producing a structured data element.

9. A system according to claim 8, wherein the instructions are further executable to produce a file having a format containing the structured data element selected from the group of XML, character separated values, spreadsheet formats and file-based database structures.

10. A system according to claim 1, wherein the structured data element produced by the performance of said producing includes reference information to the original free text for construed data.

11. A system according to claim 1, wherein the instructions are further executable to construct a library containing extracted attributes.

12. A system according to claim 1, wherein the instructions are further executable to construct a library containing extracted relational facts.

13. A system according to claim 1, wherein said instructions are further executable to perform the function of combining like relation types.

14. A system according to claim 1, wherein said instructions are further executable to perform the function of combining like attributes.

15. A system according to claim 1, wherein said instructions are further executable to perform the function of coalescing the identified attributes.

16. A system according to claim 1, wherein said instructions are further executable to perform the function of coalescing identified relation types.

17. A method for providing a service to identify and structure free text databases, comprising the steps of:

reading an access reference through said input device set, the access reference referencing a customer'"'"'s source of unstructured data, the unstructured data including free text;

accessing the source of unstructured data;

identifying text records within the free text;

linguistically parsing the identified text records;

identifying roles within the parsed text records, said identifying producing attribute extractions, each of said attribute extractions containing attribute information of the derived source text;

applying caseframes to the role extractions, said applying caseframes producing a filtered set of attribute extractions; and

producing a structured data element containing the filtered set of extractions.

18. A method according to claim 17, further comprising the step of identifying domains of the filtered set of attribute extractions.

19. A system according to claim 18, further comprising the step of assigning domain roles.

20. A system according to claim 19, further comprising the step of producing relation types.

21. A system according to claim 20, further comprising the step of coalescing the produced relation types.

22. A system according to claim 18, further comprising the step of creating a new database containing the structured data element produced in said producing.

23. A system according to claim 18, further comprising the step of producing a new relational database containing the structured data element produced in said producing a structured data element.

24. A system according to claim 18, further comprising the step of producing a file containing the structured data element produced in said producing a structured data element.

25. A system according to claim 24, further comprising the step of producing a file having a format containing the structured data element selected from the group of XML, character separated values, spreadsheet formats and file-based database structures.

26. A system according to claim 18, wherein the structured data element produced by the performance of said producing includes reference information to the original free text for construed data.

27. A system according to claim 18, further comprising the step of constructing a library containing extracted attributes.

28. A system according to claim 18, further comprising the step of constructing a library containing extracted relational facts.

29. A system according to claim 19, further comprising the step of combining like relation types.

30. A system according to claim 18, further comprising the step of combining like attributes.

31. A system according to claim 18, further comprising the step of coalescing the identified attributes.

32. A system according to claim 18, further comprising the step of coalescing identified relation types.
