Smart Code

Smart CodeSM is an improvement on annotated code that uses machine learning to identify sections of court opinions (called “extracts”) that make reference to a particular code, rule or regulation and then ranks each extract’s discussion of the code on a sliding scale from “weak” to “strong”.  It also offers the ability to search by keyword and to filter by date, jurisdiction, and legal topic.


Smart CodeSM is currently available for the entirety of the United States Code, Code of Federal Regulations, Federal Rules of Evidence, Federal Rules of Appellate Procedure, Federal Rules of Civil Procedure, and the Federal Rules of Criminal Procedure. Smart CodeSM is also live for more than 20 states and the District of Columbia, and will be available across all states by the end of 2016.

  • The Smart CodeSM tab is located along the top of the page of the statute, allowing you to quickly view opinions discussing the provision that you are researching.
  • Each extract is assigned a Strength of Discussion rating. The rating algorithm looks for characteristics indicative of a substantive legal discussion (e.g., the use of legal terminology or citations to case law) and assigns a strong, moderate, or weak rating.
