Abstract

A cost and quality controlled system for transforming collections of computer files and other electronically stored information by iterative culling and sorting so that production of relevant information can be made within estimated time and costs ranges and precision and recall ratios.

Claims

1. A computer-based method for establishing, managing, and controlling the time, cost, and quality of information retrieval and production in electronic discovery, comprising:

dividing a collection of ESI into subsets using relevance search and sorting criteria in an iterative process to cull irrelevant, false positive ESI from the ESI collection into a final production subset that has an estimated total time and cost of production that falls within imposed budgetary constraints and/or precision and recall relevancy ratios;

2. The method of claim 1 wherein the total time and cost of production of ESI is estimated based on measurements of the number, size, and types of ESI in the original set, and each ensuing production subset, based on known or projected time and cost values;

3. The method of claim 1 wherein the precision and recall relevancy ratios of an ESI production subset are projected based on human review and evaluation of samples of ESI in the production and withheld subsets;

4. The method of claim 1 wherein adjustments are made to the relevance search and sorting criteria based on human review and evaluation of samples from the subsets of each cull run to project the precision and recall of the adjusted criteria and estimate the total time and costs for production of the then remaining production subset;

5. The method of claim 1 wherein the processes are repeated until a balance has been reached that is acceptable to the user or other outside authority, such as a judge, between the estimated total time and cost of production and the projected precision and recall of the production.

6. The method of claim 1 wherein an additional process is added after production wherein the actual incurred costs and time are compared with the projected costs and time, and the actual achieved precision ratio, and if known, the recall ratio of the final production are compared with the projected ratios;

determinations are then made as to adjustments that may appropriate in future estimates of the quality of the precision and recall and of the costs and time needed to fulfill new information requests that may be received concerning the same or similar sets of collections of ESI.

7. The method of claim 1 wherein after the initial relevancy culling(s) are run, an entirely new set of search criteria are implemented, which are designed to sort the then production set into various sub-sets of potentially relevant ESI, such as “

relevant but privileged” and

“

relevant but confidential.”

8. The method of claim 7 wherein final human review and evaluation before production is limited to certain relevancy subsets of the production set and production is made of the balance of the production set without such review.

9. The method of claim 7 wherein final human review and evaluation is limited to “

relevant but privileged” and

/or “

relevant but confidential”

subsets of the production set and production is made of the balance of the production set without such review.

10. The method of claim 7 wherein the final human review and evaluation is limited to the “

relevant but privileged”

”

subset of the production set and production is made of the balance of the production set without such review.

11. The method of claim 7 wherein there is no final human review of any files before production, but select subsets of the production set, such as “

relevant but privileged” and

“

relevant but confidential,”

are withheld from production per agreement or disclosure, and the balance of the files are produced without further review.

12. The method of claims 1 and 7 wherein there is no final human review of any files before production and the final production set is produced in full.

13. The method of claims 1 and 7 wherein there are no measurements or projections of recall ratios;

instead, relevance is evaluated solely on the basis of precision.
