Abstract

A system, apparatus, method, and computer program product encoding the method are provided for expectation fulfillment evaluation. The system includes a natural language processing component that extracts sets of normalized tasks from an input expectation document and an input fulfillment document. A task list comparison component compares the two sets of tasks and identifies each match between a normalized task in the first set and a normalized task in the second set, each normalized task in the first set which has no matching task in the second set, and each normalized task in the second set which has no matching task in the first set. A report generator outputs a report based on the comparison. The report may further include one or more of statistics generated from the comparison, information on an opinion generated by opinion mining a third document, and as a list of the normalized tasks and an indication of whether the tasks were fulfilled, derived from analysis of temporal expression in the two documents. The system may be implemented as software in memory by an associated computer processor.

Claims

1. An apparatus comprising:

a system for expectation fulfillment evaluation stored in memory comprising;

a natural language processing component that extracts a first set of normalized tasks from an input expectation document and extracts a second set of normalized tasks from an input fulfillment document;

a task list comparison component that compares the first and second sets of tasks to identify;

each match between a normalized task in the first set and a normalized task in the second set,

each normalized task in the first set which has no matching task in the second set, and

each normalized task in the second set which has no matching task in the first set;

a report generator that outputs a report based on the comparison; and

a processor in communication with the memory which implements the system.

2. The apparatus of claim 1, wherein the system further comprises a temporal processing component that extracts temporal expressions in the expectation and fulfillment documents and associates them with the normalized tasks;

and

wherein the task list comparison component determines whether a normalized task which is a match is fulfilled, based on its associated extracted temporal expressions.

3. The apparatus of claim 1, wherein the system further comprises an opinion mining component that extracts an opinion from a free text document and wherein the report generator incorporates the extracted opinion in the report.

4. The apparatus of claim 1, further comprising a domain-specific thesaurus accessible to the system, whereby tasks extracted from the input expectation document and input fulfillment document are normalized.

5. The apparatus of claim 1, wherein the expectation document describes objectives for an employee in an appraisal period and wherein the fulfillment document is an appraisal of the employee'"'"'s work in the appraisal period.

6. The apparatus of claim 1 wherein the expectation and fulfillment documents are at least partially structured but do not have a one to one matching structure, and the natural language processing component utilizes the at least partial structure in generating normalized tasks.

7. The apparatus of claim 1, further comprising a user input component communicatively linked to the system for receiving a user'"'"'s input to the report to be output.

8. The apparatus of claim 1, wherein the report includes performance statistics including statistics indicating the proportion of normalized tasks in the first list that are determined to have been fulfilled.

9. A method for expectation fulfillment evaluation comprising:

natural language processing an input expectation document to extract a first set of normalized tasks and an input fulfillment document to extract a second set of normalized tasks;

comparing the first and second sets of normalized tasks to identify for each normalized task in the first set, whether there is a matching normalized task in the second set and for each normalized task in the second set, whether there is a matching normalized task in the first set;

outputting a report based on the comparison.

10. The method of claim 9, further comprising extracting temporal expressions associated with at least some of the normalized tasks and normalizing the temporal expressions.

11. The method of claim 10, further comprising determining whether a normalized task in the second set that is a match is fulfilled, based on its normalized temporal expression.

12. The method of claim 11, wherein the outputting of the report includes incorporating information in the report based on the determination of fulfilled matches.

13. The method of claim 9, wherein the comparison comprises:

identifying each normalized task from the first list which has a corresponding matching normalized task in the second list and for which their deadlines are compatible;

identifying each normalized task from the first list which has a corresponding matching normalized task in the second list and for which their deadlines are not compatible;

identifying each normalized task from the first list which has no corresponding matching normalized task in the second list; and

identifying each normalized task from the second list which has no corresponding matching normalized task in the first list.

14. The method of claim 13, wherein the method further comprises:

for each identified normalized task from the first list which has no corresponding matching normalized task in the second list, generating a warning that the task has not been fulfilled.

15. The method of claim 13, further comprising computing statistics based on the matches determined to be fulfilled.

16. The method of claim 9, further comprising opinion mining a free text document to extract an opinion therefrom and incorporating information based on the extracted opinion in the report.

17. The method of claim 9, wherein the extraction of normalized tasks comprises normalizing extracted tasks based on at least one of:

information from a domain-specific thesaurus;

structure within the document from which the task is extracted;

reducing expressions to a common normalized form, and coreference resolution.

18. The method of claim 17, wherein the expectation and fulfillment documents are at least partially structured but do not have a one to one matching structure, and the normalizing of the extracted tasks includes utilizing the at least partial structure in normalizing the extracted tasks.

19. The method of claim 9, wherein the expectation document comprises tasks that an employee is expected to work on during an appraisal period, optionally with temporal expressions indicating time periods for completion of the tasks, and wherein the fulfillment document describes tasks the employee has worked on during the appraisal period, optionally with temporal expressions indicating when the tasks were completed.

20. The method of claim 9, further comprising providing for receiving a user'"'"'s input to the report before it is output.

21. A computer program product in tangible form which encodes instructions which when executed by a computer, perform the method of claim 9.

22. A method for generating a report summarizing an employee'"'"'s performance comprising:

natural language processing an input employee objectives document, the objectives document describing tasks to be performed in an appraisal period, to extract a first set of normalized tasks;

natural language processing an input employee appraisal document, the appraisal document describing tasks performed in the appraisal period, to extract a second set of normalized tasks;

natural language processing an input comments document, the comments document including comments on the employee'"'"'s performance in the appraisal period, to extract an opinion from the comments document;

comparing the first set of normalized tasks with the second set of normalized tasks, including;

identifying each normalized task from the first list which has a corresponding matching normalized task in the second list and for which their deadlines are compatible,

identifying each normalized task from the first list which has a corresponding matching normalized task in the second list and for which their deadlines are not compatible,
