A computer system (100) for identifying information related to a context includes a context gathering service (110) configured to receive context deltas from a runtime (170) and to identify a current context state (176) . A context delta describes a change from a previous context state (175) to the current context state (176). The computer sys tem (100) also includes a semantic model (130) with elements and attributes, wherein an element represents one or more context states (175) and an attribute is assigned to the element. The computer system (100) further includes a rule interpreter (120) con figured to map the current context state (176) to a current element and a recommender service (140) configured to identify information related to the context in a knowledge source (180). The recommender service (140) is identified by one or more attributes at least one of which is assigned to the current element. |
