Early Case Assessment (ECA): From Key Word Search to Automating Document Relevance

Just before the Christmas holidays in 2007 I was teaching a CLE on the “Changes to the Federal Rules of Civil Procedure (FRCP)”. There had to have been 150 litigators, litigation service providers and consultants in the room listening to me preach about this unchartered new world called eDiscovery. My initial morning session was an overview of the current status of paper based litigation processing, how the accelerating increase in the volume of Electronically Stored Information (ESI) was steaming down the eDiscovery tracks like an out of control locomotive, how the changes to the FRCP would effect us all and what they all needed to know that day to get ready. One of topics that I touched on was the need to become more familiar with key word search methodology and the new technologies that would enable the legal industry to better manage the process of finding relevant data and assessing cases early on in the eDiscovery lifecycle. The reason that I am recalling this CLE seminar was because I will always remember the comments from an older litigator that packed up his belongings during the first break, walked up to the front and announced that, “all of this fancy new technology was never going to replace good old fashion legal hard work, understanding the relevant facts and key information for case wasn’t as complicated as I was making it sound and therefore he wasn’t going to stick around for the rest of my session.”

Well, the remainder of 149 attendees stayed and I hope that they all walked away with a better understanding of the importance of understanding key word search methodology and the new technologies that would enable the legal industry to better manage the process of finding relevant data and assessing cases early on in the eDiscovery lifecycle. Over the subsequent 18 months, key word became a big issue in the eDiscovery lifecycle and spawned a whole new technology arena called Early Case Assessment (ECA) that focused on reducing the amount of “relevant” data that had to ultimately be reviewed by a lawyer. And, having just completed another CLE this past week on ECA, I think that “most” eDiscovery professionals understand the keyword search methodology and the new technologies that enable them to better manage the process of finding relevant data and assessing cases early on in the eDiscovery lifecycle.

However, just went we thought we had it had it all figured out, a study from the Text Retrieval Conference (TREC) indicated that the keyword method tends to miss most of the relevant documents, while yielding mainly irrelevant documents. As a result, only a fraction of the relevant documents make it to the detailed review stage, while most of the documents that are submitted to review are in fact not relevant.

Moreover, the study also found that the keyword approach is typically binary, meaning that documents are either included or not. There is no graduated scale of relevance. This rigid approach does not allow for relative ranking of documents, making it extremely difficult to manage and prioritize document review.

However, as with any market that is going through a paradigm shift looking for its center and trying to normalize on some standards, the litigation technology vendors have been all over the keyword search issue and are starting to release their new solutions into production. One of the very first players in the industry to address the issue of document relevance is Equivio, a leading provider of near de-duping and email thread management technology. They have just launched Equivio>Relevance™, an expert-guided system that enhances the eDiscovery process through automated document prioritization.

Getting back to the comments of my lawyer friend that walked out of my CLE back in 2007, fancy new technology may never replace good old legal hard work. However, in today’s new world of Terabytes of potential evidence in even some of the small matters, we need all the technical help that we can get. And, it appears that Equivio is stepping up and offering us all at least a fighting chance to find the documents that we need successfully mange our cases.

The Full Text of Equivio’s Press Release is as follows:

Kensington, MD, June 22, 2009 – Equivio, a provider of software for managing data redundancy, announced today that it has launched Equivio> Relevance™, an expert-guided system that enhances the eDiscovery process through automated document prioritization.
Traditionally, attorneys use keywords to pre-filter documents prior to detailed review. According to the TREC (Text Retrieval Conference) studies, the keywords method tends to miss most of the relevant documents, while yielding mainly irrelevant documents. As a result, only a fraction of the relevant documents make it to the detailed review stage, while most of the documents that are submitted to review are in fact not relevant.

Moreover, the keywords approach is typically binary, meaning that documents are either included or not. There is no graduated scale of relevance. This rigid approach does not allow for relative ranking of documents, making it extremely difficult to manage and prioritize document review.

Equivio>Relevance™ is designed to address these limitations, introducing a higher level of flexibility, control and accuracy into the eDiscovery process. Based on initial input from a lead attorney, Equivio>Relevance uses statistical and self-learning techniques to calculate graduated relevance scores for each document in the data collection. Equivio>Relevance also uses a statistical model to calculate the precision and recall achieved by the software. This statistical model is used to provide a new level of measurability and control in the eDiscovery arena, while also helping to ensure the defensibility and transparency of the process.

Equivio>Relevance drives value throughout the eDiscovery flow through:

  • Early case assessment: Equivio>Relevance facilitates rapid assessment of the key issues and concepts in a case.
  • Culling: Equivio>Relevance achieves high levels of recall and precision, helping overcome the challenges of over and under-inclusion that characterize traditional keyword methods.
  • Review prioritization: By organizing the review set according to relevance rankings, Equivio enables prioritization of document review. This allows attorneys to immediately focus on the most relevant documents.
  • Review quality assurance: By identifying discrepancies in the responsiveness designations of Equivio>Relevance vis-à-vis the human review team, the application helps find responsive documents missed in the detail review. Similarly, the discrepancies can be used to locate documents incorrectly marked by the human review team as responsive.
Equivio>Relevance also generates a list of keywords that characterize relevant documents in the collection. These automatically-generated keywords can be used to supplement and enhance the manual list of keywords built by the legal team.

"Equivio is committed to developing and delivering innovative technologies that will help litigators improve the quality and consistency of their eDiscovery processes," said Amir Milo, CEO of Equivio. "Equivio>Relevance™ enables attorneys to review fewer and more relevant documents, lowering review costs and reducing the risk of missing key data."

Early Case Assessment Technology Getting Integrated into the eDiscovery Lifecycle

As I have been reporting over the last 18 months, Early Case Assessment (ECA) is the key  technology to reducing the cost of eDiscovery.  And, there have been no shortage of of ECA solutions to hit the market.  However, with ClearWell leading the market, all of the new ECA platforms have been standalone applications that required users to import and export data depending upon what other eDiscovery technologies that they were utilizing.  Obviously, as I have also been contending for over 18 months, a single integrated and affordable eDiscovery platform will revolutionize eDiscovery processing. 

Well, it appears that CaseCentral has answered the call by integrating ECA into their offering and enabling users to now start with ECA and extend through analysis, review, production and post-production re-use, facilitating collaborative assessments of new case merits and liabilities, application of first pass review, and real-time transfer to active review if required, all at a price point that shatters the current ECA pricing model.

Given the size of the eDiscovery market, I am sure that many vendors will follow.  And, given the history “first movers” in the technology industry, there is going to be plenty of room for additional players and several next generations of integrated ECA before the market leaders emerge.  However, CaseCentral may always be able to boast, that they were possibly the first.

The full text of the CaseCenteral press release is as follows:

SAN FRANCISCO, CA -- (Marketwire) -- 06/22/09 -- CaseCentral, the leader in secure, on-demand eDiscovery software for corporate counsel and law firms looking to simplify and take control of eDiscovery, today announced the release of the CaseCentral Early Case Assessment (ECA) offering, which is the industry's first ECA product to seamlessly integrate with active litigation review and production software. CaseCentral's integrated, multi-purpose eDiscovery review platform enables clients to start with ECA and extend through analysis, review, production and post-production re-use, facilitating collaborative assessments of new case merits and liabilities, application of first pass review, and real-time transfer to active review if required, all at a price point that shatters the current ECA pricing model.
"Many of the current Early Case Assessment tools are designed only for the matter at hand. They also frequently require a data export to another tool for active review," said George Socha Jr., Esq., founder of Socha Consulting. "An approach that treats ECA as an integrated part of the overall review and analysis process has the potential to improve both transparency and consistency, decreasing risk and benefiting both inside and outside counsel."

Integrated, Multi-purpose Review Platform

The CaseCentral review platform delivers ECA with close proximity to active review, meaning that no export of data to other tools is required. Clients may rapidly create a new case for active review directly from within the ECA application, increasing consistency and decreasing cost and time. CaseCentral delivers these benefits with centralized data management and enterprise-class security, reducing the risks typically borne by corporations when they transmit proprietary and confidential data outside the firewall to multiple law firms and service providers. The CaseCentral ECA offering is useful to provide first pass review at the time of preservation, post-collection in preparation for 26(f) meet and confer or for performing scenario testing and risk forecasting on large data sets, benefiting both inside and outside counsel.

Designed for Collaboration

The CaseCentral review platform uniquely supports the virtual teams that are typical in eDiscovery review -- corporate legal potentially located in multiple states and time zones, law firms doing review work outside the corporate firewall and often outside review houses or LPOs performing critical review from locations across the country and even from other countries. This collaborative environment provides critical transparency of the review process to both inside and outside counsel and speeds the time to resolution.

Enables Use of Context from Previous Matters

Existing early case assessment products are usually designed only for the matter at hand, not to take advantage of previous matters. The CaseCentral review platform allows clients to manage multiple matters and enables re-use of work product or context from prior matters, including searches, production history and coding history, to aid in either Early Case Assessment or active eDiscovery review activities, increasing consistency and decreasing risk, cost and time.

Radical New ECA Pricing Model

Pricing for CaseCentral early case assessment starts at $10/GB/month or $120k/TB/year, which is two orders of magnitude less than competitive products, enabling clients to cost-effectively consider much larger data sets for ECA during first pass review. CaseCentral ECA pricing also takes away unpredictability making it easier to budget for ECA activities. Contemporary early case assessment tools charge clients a significant premium for perceived value, often starting at $100k/100GB, which equates to $1,000/GB. ECA can be about small data sets (Gigabytes) or about very large data sets (Terabytes) and current pricing discourages or limits the amount of data that can be considered during early case assessment before ultimately culling down the data set to a smaller amount for active review. This approach forces inside and outside counsel to take risks to limit the data set for ECA and active review.

"CaseCentral has taken the visionary step of treating Early Case Assessment (ECA) like just another phase of the review process," said Steve d'Alencon, chief marketing officer, CaseCentral. "This approach, coupled with CaseCentral's radical new ECA pricing model, moves the value equation for clients away from tactical, independent tools and towards an integrated, multi-purpose eDiscovery review platform."

CaseCentral ECA functionality allows attorneys to:

-- Consider strategies, perform analysis, evaluate liability and eliminate irrelevant data.
--  Analyze any given data set to cull down to only relevant and
    responsive data before moving into active review.
--  Collaborate securely with inside and outside counsel without
    compromising any active litigation reviews.
--  Ability to collect preservation metadata related to the legal hold
    (i.e. case name, sources, file paths, time and date of collection,
    applicable retention policy, etc.)
--  Employ file extension filtering and NSRL database filtering (de-NIST)
--  Utilize keyword or conceptual term search filters and conceptual
    classification across terabytes of data with 100% fully indexed metadata,
    full email thread support, duplicate management and near-duplicate
    identification.
--  Based on active attorney designations, re-evaluate and modify/remove
    keywords, custodians and concepts to cull irrelevant documents during
    review.  (i.e.: keywords with low responsive rates may be dropped from
    collections.)
--  Create content profiles to quickly locate potentially privileged and
    confidential content, as well as segregating non-relevant documents.
    (i.e.: create a 'smart folder' for spam content.)
--  Report metrics regarding data volumes, data types, custodians and
    collection metadata.
--  Classify documents by potential treatment (aka: potentially
    privileged) and move them directly into active review.
