A service can become adaptive if it can change its
configuration, behavior and appearance based on the context, where “context
is any information than can characterize the situation of the entity.
An entity is a person, place or object that is considered relevant to
the interaction of a user and an application including the user and the
application themselves”. So based on this definition, which is quite
general, context is any information that characterizes the service and
its user, their physical and execution environments (including the
devices used) and the network that connects them. Context information
has also quality as it depends on the way it is sensed or derived, the
time that it is produced and delivered, the level of detail and other
factors. [CD-JRA-1.3.2] {GEN: Quality Attribute}

Note: The definition stated for this term is taken from the S-Cube Quality Reference Model, which was intended to provide S-Cube members with a unified terminology for describing quality attributes of service-based applications (see deliverable CD-JRA-1.3.2).
