SMILES or the Simplified Molecular-Input Line-Entry System is a line notation "language" used by chemical information systems to represent a molecule and to communicate its structure from one place to another using short ASCII strings. SMILES strings can be imported by most molecule editors for conversion back into two-dimensional drawings or three-dimensional models of the molecules.[1]

The original SMILES specification was developed by Arthur and David Weininger in the late 1980s[2], with funding assistance from the Environmental Protection Agency's Mid-Continent Ecology Division-Duluth.[3] It has since been modified and extended by others, most notably by Daylight Chemical Information Systems Inc.

In 2007, an open standard called "OpenSMILES" was developed by the Blue Obelisk open-source chemistry community.[4] Other linear notations include the Wiswesser Line Notation (WLN), ROSDAL, and SYBYL Line Notation.

SMARTS

SMARTS is related to the SMILES line notation that is used to encode molecular structures, and like SMILES it was originally developed by David Weininger and colleagues at Daylight Chemical Information Systems.[2]
