Managed Document Review (MDR) is a crucial aspect of the eDiscovery process, which involves the identification, review, and organization of potentially relevant documents during legal proceedings or investigations. The volume of electronically stored information (ESI) has grown significantly over the years, making document review a challenging and time-consuming task. MDR employs various techniques to streamline the review process and ensure efficiency and accuracy. Here are some of the key techniques used in Managed Document Review:

Technology-Assisted Review (TAR):

TAR, also known as Predictive Coding or Computer-Assisted Review, involves using machine learning algorithms to categorize and prioritize documents based on relevance. Initially, a small subset of documents is reviewed by human reviewers, and the system learns from their decisions to predict relevance for the remaining documents. TAR significantly reduces manual review efforts and improves accuracy.

Keyword Search:

Keyword searching is a traditional method where specific keywords or phrases are used to identify relevant documents. While it is a useful technique, it may have limitations, such as producing too many irrelevant results or missing critical documents if the chosen keywords are not comprehensive enough.

Concept Clustering:

Concept clustering groups similar documents together based on themes, topics, or concepts. This technique helps to identify documents that are related to specific issues or events without relying solely on exact keyword matches.

Email Threading:

In many legal cases, email communication plays a significant role. Email threading groups email chains or conversations together, eliminating duplicates and presenting the information coherently. This approach ensures that reviewers can understand the context of the emails efficiently.

Near-Duplicate Detection:

Near-duplicate detection identifies documents that are very similar to each other, often differing only in minor ways (e.g., different recipients or timestamps). Reviewing near-duplicates can be redundant, so this technique helps to reduce review time and avoid duplication of efforts.

Date Range Filtering:

Filtering documents based on specific date ranges can be helpful, especially when the relevance of documents is limited to a particular timeframe.

Privilege Detection:

It’s essential to protect privileged and confidential information during document review. Privilege detection tools help identify documents that may be protected by attorney-client privilege or other legal privileges, preventing inadvertent disclosure.

Document Metadata Analysis:

Metadata analysis involves examining document properties, such as creation date, author, or file type. Analyzing metadata can provide valuable insights into the relevance and authenticity of the documents.

Quality Control and Sampling:

Regular quality control checks and random sampling are essential to ensure consistency and accuracy in the review process. These measures help identify potential errors or inconsistencies and maintain the overall quality of the review.

Reviewer Training and Guidelines:

Providing clear instructions and guidelines to the document reviewers is crucial to maintaining consistency and ensuring that the review aligns with the case’s objectives.

The goal of using these techniques is to streamline the document review process, reduce the number of irrelevant documents, and identify relevant information efficiently. Combining technology and human expertise is key to achieving an effective and defensible managed document review.
