Computer-Assisted Review

Definition of Computer-Assisted Review

Computer-Assisted Review (CAR) refers to a technology-based process that aids in document review and analysis during legal proceedings. It utilizes machine learning algorithms to analyze and categorize large data sets, thus increasing accuracy and efficiency. CAR is commonly used in e-discovery, litigation, and regulatory compliance to reduce manual labor and save time.


The phonetic transcription of the keyword “Computer-Assisted Review” in the International Phonetic Alphabet (IPA) can be represented as:/kəmˈpyutər əˈsistɪd rɪˈvju/

Key Takeaways

  1. Computer-Assisted Review (CAR) combines artificial intelligence with human expertise to analyze and categorize large volumes of data efficiently and accurately.
  2. CAR allows legal professionals to focus on more complex tasks, reducing the time and cost associated with manual document review.
  3. Continuous Active Learning (CAL) is a key component of CAR, as it enables the system to improve and refine its predictions based on the ongoing feedback and input from the legal experts.

Importance of Computer-Assisted Review

Computer-Assisted Review (CAR) is an important technology term as it refers to the process of leveraging advanced algorithms and artificial intelligence to efficiently analyze and categorize large volumes of electronic documents during legal and regulatory examinations, such as e-discovery or compliance investigations.

The significance of CAR lies in its ability to save time, reduce human error, and lower costs associated with manual document review.

By using a combination of machine learning and human validation, CAR improves accuracy, precision, and consistency of the analysis, enabling legal professionals to more effectively focus their efforts on relevant data and make better-informed decisions.

Ultimately, CAR streamlines the document review process, making it a valuable tool in today’s increasingly data-driven legal landscape.


Computer-Assisted Review (CAR), also known as Technology-Assisted Review, is a data-analyzing technology aimed at enhancing the efficiency and accuracy of document review and analysis during electronic discovery (eDiscovery) and litigation phases of legal proceedings. The purpose of CAR is to reduce the time, effort, and cost associated with manual processing and organization of large volumes of documents, while maintaining a high level of precision, reliability, and relevance in the end analysis.

Employing sophisticated algorithms, machine learning techniques, and artificial intelligence, this technology identifies relevant information from vast pools of data in a fraction of the time it would otherwise take a human. The use of Computer-Assisted Review is becoming increasingly essential in the legal industry, where law firms and corporations must manage vast and growing quantities of digitized information.

Its application ranges from locating key emails and documents supporting lawsuits, to discovering sensitive information, and organizing confidential files. Furthermore, as the technology advances, CAR plays an instrumental role in adapting legal practices to evolving data landscapes and mitigating risks associated with non-compliance, data breaches, and critical intellectual property issues.

As a result, law firms, corporate legal departments, and regulatory authorities continue to rely on Computer-Assisted Review for its ability to improve the efficacy, speed, and precision of eDiscovery processes in the dawn of the digital age.

Examples of Computer-Assisted Review

Example 1: Legal e-Discovery ProcessIn the legal industry, the e-Discovery process involves identifying, collecting, reviewing, and producing electronically stored information (ESI) in response to litigation or government investigation. Computer-Assisted Review (CAR) technology, also known as Technology-Assisted Review (TAR) or predictive coding, is used to help identify relevant documents quickly, thereby speeding up the process, reducing human error, and cutting down costs.Example 2: Medical Research and Data AnalysisIn the medical field, researchers analyze thousands of medical journals, articles, and reports to study diseases, develop treatments, and improve healthcare decisions. Due to the massive amount of data available, using CAR technology can help researchers save time and identify accurate and relevant information rapidly. CAR allows them to process vast quantities of text, categorize documents by topics, and find relationships in the data, accelerating the whole process.Example 3: Intellectual Property and Patent ReviewIn the field of intellectual property, particularly patent law, there is a constant need to review patent applications and analyze existing patents. CAR technology can streamline this process, allowing patent examiners to concentrate more on critical analysis and assessments. Using CAR, these professionals can identify relevant prior art (previous patents or published articles) and automatically categorize the documents, increasing the efficiency and accuracy of the patent examination process.

FAQ: Computer-Assisted Review

What is computer-assisted review?

Computer-assisted review, also known as technology-assisted review or TAR, is a process that uses machine learning and intelligent software to identify, categorize, and analyze large sets of documents and electronic data. It helps streamline and reduce human efforts in the review process, especially in legal and e-discovery contexts.

How does computer-assisted review work?

Computer-assisted review works by analyzing a sample of documents provided by human reviewers and generating a predictive model based on their decisions. This model is then applied to the entire document set, allowing the system to classify and rank documents based on relevance. As the system processes more data, it continuously refines the model, improving its accuracy and efficiency.

What are the benefits of computer-assisted review?

There are several benefits to using computer-assisted review, including increased efficiency, reduced costs, and improved accuracy. By leveraging artificial intelligence and machine learning capabilities, computer-assisted review can handle large volumes of data much faster than human reviewers alone. Additionally, it can help ensure consistency and reduce the risk of human error, providing a higher degree of accuracy in document review.

What industries use computer-assisted review?

While computer-assisted review is commonly used in the legal industry for e-discovery purposes, it can also be applied across various industries and sectors, including healthcare, finance, government, corporate, and more. Any industry that requires large-scale document review and analysis can benefit from implementing computer-assisted review and its AI-driven capabilities.

Is computer-assisted review secure?

Security is a critical factor in computer-assisted review. Reputable service providers ensure secure data handling and protection through the use of encryption, secure communications, and strict internal access controls. It is essential to verify the security standards and certifications of any technology-assisted review platform to ensure the confidentiality and integrity of sensitive data.
