Equivio Themes: Shifting The eDiscovery Focus Back To Lawyers Looking For Evidence

This article is written by Chris Dale of the UK-based eDisclosure Information Project in conjunction with Equivio. Equivio develops software for eliminating data redundancy and for helping lawyers and investigators to cut through large volumes of documents quickly and efficiently to find the few which matter.

The emphasis in eDiscovery/eDisclosure in recent years has been on mechanics and process, as ever-increasing volumes, tighter restrictions on time and cost, and fear of sanctions have relegated the lawyers' investigative role behind that of IT specialists and data analysts. Attention is shifting, in many jurisdictions, to finding what really matters, and to the role of senior lawyers and case strategists and in achieving that quickly. Equivio Themes is designed for just that purpose. The benefits go beyond the case-by-case advantages of evidence-finding, budgets, strategy and tactics. Lawyers prefer being lawyers to being merely part of a process, and software designed to maximize human input restores the lawyers’ traditional role in 21st-century guise.

Equivio Themes

Equivio Themes is the latest addition to Equivio Zoom, a platform that includes Equivio's tools Near-Duplicates, Email Threads, the predictive coding tool Relevance, and other applications for grouping, refining and reducing document volumes. Underlying these applications are sophisticated text analytical tools: for example, one document is a near-duplicate of others because it has the requisite degree of similarity in its content, and the predictive coding algorithms in Equivio Relevance analyze the attributes that distinguish relevant from non-relevant documents. Equivio Themes carries this to the next level, bringing software analysis closer to the way humans think.

One of the recurring features in Equivio's applications is that their names clearly relate to their functions, and Equivio Themes is no different. A “theme” is a central topic that runs through a narrative – what it is about; in music, it is a melodic subject that is developed with variations. A document collection will have many themes, and any one document may touch on multiple themes and variations on those themes. A document is not just a single entity, nor is it merely a collection of potential keywords – it may be “about” subjects without referring directly to them, and multiple documents may, perhaps subliminally, have more than one topic in common with others. Few conspirators describe their activities as a “conspiracy;” anti-competitive behavior is rarely described as such; and instructions to delete or shred documents are usually couched in indirect terms. One needs sophisticated tools to flush out things of this kind.

Equivio Themes can be used at any point in a case, but its greatest value comes at the beginning. Its first stage is one of computer analysis of semantic content, identifying salient themes and giving them meaningful labels.

Having built a vocabulary of themes, the application then uncovers the network of relationships between them and the documents, displaying the results in graphical form or as lists according to the user's choice. Just this step alone is valuable: one of the characteristics of a discovery collection is that the user does not know what is in there, and anything that makes it easy to understand – or just see – this is valuable.

The collection of themes provides a high-level view of the content, something that it would take weeks of work to produce by conventional means. The user – the senior lawyer, subject-matter expert or case strategist – can pick a theme and explore it, navigating laterally to related themes, and drilling downwards for more detail with a “find similar” documents function. Because Themes is part of Equivio Zoom, the other tools are immediately at hand, allowing different ways of slicing and dicing the data without leaving the application.

Applying Equivio Themes To eDiscovery And Investigations

There is an obvious level at which it is beneficial to be able to identify key documents quickly. Time and cost are saved if one can eliminate, or at least relegate, documents of little or no significance and focus on those that are important. Civil jurisdictions are increasingly requiring parties to define the scope of proposed discovery/disclosure exercises at an early stage. In particular, the procedure rules of England and Wales now require parties to lodge a Disclosure Report 14 days before the first case management conference, which broadly identifies documents and estimates the costs of managing them; some cases require formal budgets.  The test of proportionality, which is gaining significance in many jurisdictions, is not met by a prolonged and expensive information-gathering exercise, even if the timescales allowed it.

There are three other levels, however, at which the early acquisition of knowledge about the document population becomes significant: one strategic, one tactical and one to do with the basis for charging for the discovery/disclosure exercise.

The strategic objective is what is commonly known as early case assessment. Clients do not want to spend money fighting hopeless cases, and, as with any other project on which they embark, they want to know both their prospects and the likely costs. These two components are the key elements of a risk analysis. If this matters in civil litigation, it potentially matters more for a regulatory investigation, when a client wants to know how strong his negotiating position is and to identify the ramifications of the enquiry – not just “Do we have a problem?” but “How wide does this problem go?” The same applies to internal investigations, where the security of the business, its reputation and its share price may depend on getting quickly to the facts.

Knowledge of one’s own document population also affects tactics. The ability to rebut an allegation promptly, to counter adverse suggestions made by opponents or regulators, or to advance arguments at an early stage that may dispose of the problem all amply justify the detailed knowledge of the documents that Equivio Themes can bring. Knowledge of one's own evidence is like knowledge of the issues, the facts and the law – it impresses less well-prepared opponents.

The sort of analysis that Equivio Themes allows also gives the lawyer a good feel for the potential costs of giving discovery/disclosure. If, to take figures that are often used, discovery can consume 40 percent of a litigation budget with review costing 70 percent of that, then the ability to get a feel for the reviewable population is clearly an asset. Corporate clients are increasingly requiring their external lawyers to enter into alternative fee arrangements – alternative, that is, to an hourly charging rate for an unspecified number of hours. Clients are expecting their lawyers to fix or cap their fees; you cannot realistically do that without an early idea of the size of the job that confronts you.

Using Equivio Themes To Keep Litigation Departments Competitive

The value of intelligent software like Equivio Themes goes beyond the ability to find evidence quickly and beyond the budgetary, strategic and tactical benefits outlined above. It enables law departments to compete with less well-equipped rivals, both to win work and to attract talent.

A combination of technology and outsourced services like managed document review poses a serious threat to law firms whose profits have depended hitherto on maximizing the hours of large teams of associates. They face competition also from other business models – the major consulting firms are one example – that can capitalize on their technology skills, separating the mechanics of search from the purely legal aspects of the task. Law firms face the threat also that clients can acquire for themselves technology like Equivio Themes and do some of the heavy lifting before the lawyers ever get involved.

The corollary to that threat is opportunity for those willing to take it. You no longer need to be a big firm to manage document-heavy litigation. The use of software like Equivio Themes, as described in the opening section of this article, allows senior and well-qualified lawyers – the strategists and the tacticians – to get a grip on the case, to assess prospects and risks, and to decide how a case is to be run. With that stage achieved, the rest of the discovery exercise becomes a largely mechanical task performed by technology and outsourcing, requiring input from those same senior lawyers but not needing teams of associates.

Lawyers appreciate this for more reasons than the costs savings. Intelligent technology like Equivio Themes is an enabler of the skill and knowledge on which lawyers pride themselves. This has benefits extending into staff recruitment and retention – the better young lawyers are more likely to be attracted to a firm that uses such technology than to one that will waste their talents on manual review.


Document populations continue to increase while lawyers, both in-house and external, are expected to contain timescales and costs. Technology has largely solved the problem of managing large volumes at a basic level, thanks to fast processing, broad Internet pipes and powerful search technology. Together, perhaps, these things allow us to keep pace with ever-larger volumes.

Equivio Themes allows a jump up from this level. It does so by a combination of very sophisticated text analytic tools and by an interface and set of functions that closely map to the thought processes of lawyers and investigators, suggesting avenues to be explored or quickly discarded, not as a substitute for their input but as an enabler of faster, more meaningful and more systematic ways to explore a document collection.
