14. A computer program product for assisting system administration comprising a non-transitory computer usable storage medium including a computer readable program, wherein the computer readable program when executed on a computer causes the computer to: store system information to form a knowledge base; receive administration query terms related to a system administration objective; store metadata of entity-objective indexes in the knowledge base, wherein the metadata of entity-objective indexes comprise meta information for at least one entity, wherein an entity comprises one or more of a logical device and a physical device; create an abstract dependency tree for logical and physical entities that are relevant to the administration query terms; apply a degraded recipe on each of the entities in the abstract dependency tree; and map the administration query terms to information extraction tasks to extract relevant entities and objectives and apply a rule to the extracted entities and objectives for presenting the extracted entities and objectives in a ranked order.
