Limits of a Relativity Analytics Index

Note that when an analytics index is populated in Relativity, preprocessing is performed which affects how the content of the sources for the index in saved searches are used in the index.

In addition to the filters selected on the Analytics Index Information form filled out when the index is created, which can remove email headers, footers, and signatures, and stop words which are too used too often . . .

. . . numbers and symbols will be excluded from the index. The text will also not be case sensitive. All of the searchable text will be lowercase.

Draft Emails Are Inclusive

Email threading is performed in order to avoid the need to read the separate parts of long email threads over and over again.

Relativity defines inclusive emails as those which must be reviewed- they include all of the content for a thread. Non-inclusive emails do not need to be reviewed - but note that the threading analysis does not take the email headers into account.

Duplicate spares are emails which contain the same content as other emails and so do not need to be reviewed.

DRAFT emails are an anomaly. Draft messages are never treated as duplicate spares. They will always be marked as inclusive, and be considered unique content.

Draft emails have this icon with a pencil in the email threading visualization:

So if you have these added to a review don’t think it means they were never sent!

TCR

TCR is a commonly used abbreviation for ‘total

cost of review’ This is the amount spent on a complete e-discovery workflow. A team with Relativity analyzed TCR and has reported its results here.

As the below chart shows:

Review cost still takes up most of the budget, with processing cost coming in a distant second. Collection and hosting fees are minimal.

The study shows that targeted collection will reduce TCR in the long run, if not in the first couple of months.

According to the study, if targeted collection is performed, in the end TCR will be reduced by almost a third.
