Data → SolutionTo model a solution from data, we use machine learning, clustering and classification techniques, pattern recognition and predictive analytics.
Knowledge → RepresentationTo represent explicit knowledge structures, we use domain specific languages and knowledge graphs. Knowledge representations are not only human engineered by knowledge acquisition but often derived by reasoning and learning models.
Data + Knowledge
→ ML (Machine Learning) + MR (Machine Reasoning)Often effective solutions are achieved by hybrid models, combining: - data driven machine learning (deep ML on data, ML on data features), - knowledge driven machine reasoning (MR on knowledge representations and knowledge graphs) - knowledge driven machine learning (ML on knowledge graphs).
Text → ValueTo extract and identify value from text sources, we use natural language processing, text mining and linked data.
ProcessingTo power advanced information retrieval and algorithmic processing, we use memory-based index structures, distributed computing and big data technologies.

Proactive predictive and prescriptive analytics
Reactive/descriptive analytics activities and architectures are typically well supported by a linear process of data ingestion, consolidation, integration and aggregation to macro-level data models and prepared analysis dimensions. This since analysis and its underlying data needs, typically start from proposed hypothesis which one refines, confirms and supports using underlying data. This can be supplemented by looking for trends on macro- and/or aggregated level. The processes and their underlying data are typically all relying on operational data sources, which implies that there is often no distinction needed between operational data flows and models, and the pure analytical data flows and models.Proactive/predictive-prescriptive analytics can have quite a different functional and technical architecture, often implying a more cyclic process, starting from the data, building information and patterns, which are transformed after analysis to insights, to take action and create value. Both actions and changes in the environment give rise to changes in the data, which again drives the next cycle in the process.
