Data the new oil

Clive Humby, mathematician and data scientist, already stated in 2006: "Data is the new oil! 

"Data is the new oil. It's valuable, but if unrefined it cannot really be used. It has to be changed into gas, plastic, chemicals, etc to create a valuable entity that drives profitable activity; so must data be broken down, analysed for it to have value."

People can use data and create value by accessing contextual knowledge such as rules, dictionaries or keyword registers and linking the resulting information with the stored content.

If, on the other hand, machines are supposed to assume decision tasks in reference to the stored knowledge or exchange data, which themselves contain information about how to structure and interpret them (so-called metadata), they need a representation of the underlying terms and their correlations. 

With the help of ontologies, such knowledge representations can be modelled. Unlike data models, which are mainly intended for use in IT, ontologies represent knowledge in a form that can also be used by IT non-professionals. Ontologies and the associated tools are suitable for use in companies that, with the help of their employees and their expertise, want to create formal definitions of terms and their relationships as a basis for a common understanding in the company.

The value of an ontology stands or falls with the extent of the recognition and approval ("ontological commitment") it obtains within the company. In most cases, such acceptance is easier to achieve the more decision-makers and stakeholders are involved in the design process. On the other hand, the complexity usually increases with the number of people involved in the concept.

With the help of ontologies, valuable information can be generated from the raw ingredient "data". We help you to select suitable tools for the creation of generally valid and understandable ontologies. These ontologies can later be added to websites, ERP- or shop- systems.  

For example: Hagen
The term "Hagen" can be a city in Germany, a ship's name, the first name of a person or their surname.

A web search with the keyword "Hagen" would provide more relevant results with the additional information available in this way.

Forschungsprojekt Simple Anno, Konsortialführung [j]karef GmbH, Rüdiger HenriciDer Anteil an e-Learning in der Weiterbildung und die Nachfrage nach digitalen Inhalten zur Entscheidungsunterstützung in der beruflichen Praxis steigen stetig an. Gründe dafür, sind u.a. die bessere Vereinbarkeit von Familie und Beruf, geringere Kosten als bei Präsenzfortbildungen und die adhoc Verfügbarkeit von Informationen. Dabei gehört die Zukunft völlig neuen Lern- und Lehrkonzepten die sich innerhalb der digitalen Welt neu erfinden. Doch sind für die Erstellung von e-Learning Inhalten oder Tutorials qualitative hochwertige Bilder, Texte und Videos notwendig.

Ziel der Entwicklung ist ein System für Verlage, e-Learning Anbieter und Arztpraxen, das Autoren mittels eines halbautomatisches Assistenzsystems dabei unterstützt, Inhalte einfach und systematisiert mit Metainformationen zu versehen. Dazu sollen einem Autor auf der Basis eines von ihm eingegeben Freitextes, konkrete Vorschläge für die Metabeschreibung innerhalb definierter Kategorien unterbreitet werden. Zusätzlich werden Autoren bei der Festlegung von Verwertungsrechten und bei der Durchsetzung der Bezahlung ihrer Inhalte unterstützt.
