Insights into the Data Analytics of Managed Document Review

Managed document review is a crucial process in the field of data analytics, particularly in the context of legal and regulatory investigations, litigation, and due diligence. It involves reviewing and analyzing large volumes of documents, such as emails, contracts, memos, and other relevant materials, to identify pertinent information, assess their relevance, and make informed decisions based on the findings.

Here are some insights into the data analytics of managed document review:

Data Preparation: Before conducting document review, data analysts need to preprocess and organize the documents. This step involves data extraction, text normalization, and structuring to facilitate efficient analysis. Techniques like optical character recognition (OCR) may be used to convert scanned documents into searchable text.

Data Filtering and Sampling: To manage the vast amount of documents, data analysts often employ filtering techniques to reduce the dataset’s size. This can involve excluding irrelevant file types, eliminating duplicates, or applying search filters based on keywords or metadata. Additionally, sampling methods may be used to select representative subsets for analysis, especially when dealing with a large document population.

Technology-Assisted Review (TAR): Technology-assisted review, also known as predictive coding or machine learning-assisted review, employs algorithms to automate the document review process. It involves training the algorithm using a subset of documents that are reviewed manually by human experts. The algorithm then predicts the relevance of documents in the remaining dataset, helping to prioritize the review process.

Text Analytics and Natural Language Processing (NLP): Text analytics and NLP techniques are applied to extract meaningful insights from the text within the documents. These techniques include entity extraction (identifying names, organizations, dates, etc.), sentiment analysis, topic modeling, and clustering. NLP also enables techniques like named entity recognition and relationship extraction, which can provide additional context to the analyzed documents.

Conceptual Analysis: In addition to keyword-based searches, data analysts may perform conceptual analysis to identify documents related to specific topics or themes. This approach involves analyzing the underlying concepts and context within the documents rather than relying solely on exact keyword matches. Techniques like Latent Semantic Analysis (LSA) or Latent Dirichlet Allocation (LDA) can assist in uncovering hidden patterns and relationships in the document corpus.

Quality Control and Iterative Refinement: Document review is an iterative process that requires continuous quality control. Data analysts may establish protocols to ensure consistent and accurate review across the team. This can include regular meetings, peer reviews, and calibration exercises to maintain consistency in document categorization and relevance determination. Feedback loops and refinements are employed to improve the efficiency and accuracy of the document review process over time.

Data Visualization: Visualizations play a vital role in presenting the insights gained from document review. They help communicate patterns, relationships, and trends within the document corpus. Visualization techniques like word clouds, network graphs, topic clusters, and timelines can be employed to summarize and present the findings effectively.

Continuous Learning and Improvement: Managed document review processes can benefit from continuous learning and improvement. As the review progresses, analysts can identify patterns and insights that contribute to refining search queries, optimizing sampling strategies, and enhancing the effectiveness of the review. By applying lessons learned from previous reviews, subsequent projects can be executed more efficiently and accurately.

These insights highlight the key components of data analytics in managed document review. The application of advanced technologies, such as TAR, NLP, and visualization tools, can significantly enhance the efficiency, accuracy, and effectiveness of the document review process, ultimately leading to better decision-making and insights extraction.
