Effective problem solving through fuzzy logic knowledge bases aggregation
Kolomvatsos, K. (2015)Cooperative problem solving has attracted great interest in the research community. A number of nodes can cooperate to reach a common goal which is the solution to a specific problem. Through a team effort, nodes try to ... -
An efficient Recommendation System based on the Optimal Stopping Theory
Kolomvatsos, K.; Anagnostopoulos, C.; Hadjiefthymiades, S. (2014)A Recommendation System (RS) aims to deliver meaningful recommendations to users for items (e.g., music and books), which are of high interest to them. We consider an RS which directly communicates with a set of providers ... -
A time optimized scheme for top-k list maintenance over incomplete data streams
Kolomvatsos, K.; Anagnostopoulos, C.; Hadjiefthymiades, S. (2015)A large number of contemporary research efforts focus on incomplete data streams handling. These efforts, usually, focus on the creation and maintenance of top-k lists useful to provide efficient responses to top-k queries. ... -
Time-optimized user grouping in Location Based Services
Anagnostopoulos, C.; Hadjiefthymiades, S.; Kolomvatsos, K. (2015)We focus on Location Based Services (LBSs) which deliver information to groups of mobile users based on their spatial context. The existence (and non-trivial lifetime) of groups of mobile users can simplify the operation ...
