Abstract

KPIOnto introduces a logical representation of indicators and their formulas, allowing to make the algebraic relationships among indicators explicit.

The main classes of KPIOnto include: Indicator, Dimension, Level, Member and Formula. Indicator describes the metrics enabling performance monitoring. A Dimension is the coordinate/perspective along which a metric is computed. Following the multidimensional model, a dimension is usually structured into a hierarchy of Levels, where each level represents a different way of grouping elements of the same dimension. Indeed, each level is instantiated in a set of elements known as Members of the level. An indicator can be either an atomic or a compound datum, built by combining several lower-level indicators. Dependencies of compound indicators on its building elements are defined by means of algebraic operations, that is a Formula capable to express the semantics of an indicator. A formula describes the way the indicator is computed, and is characterised by the aggregation function, the way the formula is presented, the semantics (i.e., the mathematical meaning) of the formula, and references to its components, which are in turn (formulas of) indicators.
