A COMPUTATIONAL ONTOLOGICAL MODEL FOR MACHINE-UNDERSTANDABLE DATA IN ARTIFICIAL INTELLIGENCE

Yargan, Dilek
Big Data is believed to be one of the most important phenomena of the century due to its transformative effects and those undeniable effects of the data deluge in the fields of industry, science, and the Web -the fundamental wheels upon which today's world makes progress- are, however, hardly transformative. If Big Data is to lead to revolutions in these fields, the machine must be autonomous, that is, to perform higher-order cognitive skills, such as making decisions, inferences, and recommendations. The condition for an autonomous machine is its ability to understand and process Big Data. So, this work aims to determine the foundations for machine-understandability and accordingly determine the conditions for an autonomous machine. In this respect, this work proposes a machine ontology, Ontology 4.0, which represents phenomena in terms of their semantic properties in a relation-based fashion and processes semantic properties according to their types. Adapted from trope and type theories, this ontology forms the basis for machine-understandability. However, due to computational limitations from type theories, the semantic properties are discussed to be represented with nonextensional ontological objects, viz., urtropes, which turn out to be the building blocks of Ontology 4.0. Category theory is adapted as a formalization tool to implement this structure in the machine. Consequently, providing basis for machine-understandability, Ontology 4.0 is a machine ontology that harmonizes urtrope and modified category theory.

Paradigm shifts such as digital transformation and Industry 4.0 produce complex data, also called big data. Businesses increasingly focus on exploiting big data for competitive advantage, leveraging data science. However, many industries cannot effectively leverage data science since no comprehensive approach allows strategic planning for organization-wide data science projects and data assets. After recognizing the industry`s need, this thesis explores the Data Science Roadmapping Framework`s (DSR) develop...

A progressive approach for processing satellite data by operational research
KUTER, SEMİH; Weber, Gerhard-Wilhelm; Akyürek, Sevda Zuhal (Springer Science and Business Media LLC, 2017-07-01)
Satellite data, together with spatial technologies, have a vital importance in earth sciences to continuously monitor natural and physical processes. However, images taken by earth-observing satellites are often associated with uncertainties due to atmospheric effects (i.e., absorption and scattering by atmospheric gases and aerosols). In this paper, a more adaptable approach for the removal of atmospheric effects from satellite data is introduced within an operational research perspective by utilizing nonp...
