Adaptivity for knowledge content in the semantic web
(2008)The focus of this report is the adaptivity issue for Learning Objects owned by Learning (Web) Services. We address this issue based on the Concept, Resource, Order, Product (CROP) Reference Architecture that we briefly ... -
Algorithms for processing the group K nearest-neighbor query on distributed frameworks
(2021)Given two datasets of points (called Query and Training), the Group (K) Nearest-Neighbor (GKNN) query retrieves (K) points of the Training with the smallest sum of distances to every point of the Query. This spatial query ... -
A comparison of distributed spatial data management systems for processing distance join queries
(2017)Due to the ubiquitous use of spatial data applications and the large amounts of spatial data that these applications generate, the processing of large-scale distance joins in distributed systems is becoming increasingly ... -
The Complexity in the Study of Spatial Networks: an Epistemological Approach
(2018)Provided that the study of complex networks has reached a crucial measure to be considered by many researchers as a separate discipline, the so-called Network Science (NS), the assessment of this field under the epistemological ... -
Computational methods and optimizations for containment and complementarity in web data cubes
(2018)The increasing availability of diverse multidimensional data on the web has led to the creation and adoption of common vocabularies and practices that facilitate sharing, aggregating and reusing data from remote origins. ... -
Conceptual universal database language: Moving up the database design levels
(2009)Today, the simplicity of the relational model types affects Information Systems design. We favor another approach where the Information System designers would be able to portray directly the real world in a database model ... -
Database design of a geo-environmental information system
(2014)Environmental protection from productive investments becomes a major task for enterprises and constitutes a critical competitiveness factor. The region of Central Greece presents many serious and particular environmental ... -
Design and functionalities of a Hybrid Personalized Learning Electronic Assistant
(2016)Throughout the last decade a number of Personalized Learning Environments have been proposed encompassing various personalization techniques, in order to provide learning material adapted to the specified user's requirements. ... -
Development of a district information system for water management planning and strategic decision making
(2015)The overall objective of this work is the development of a District Information System (DIS) which could be used by stakeholders for the purposes of a district day-to-day water management as well as for planning and strategic ... -
