Data Warehouse / Knowledge Base System

Distributed Data Warehouse/Data Marts of Streamed Linked Data as Knowledge Base System

ClueBoomBus is an application to manage distributed data warehouse/data marts of streamed linked data. It's based on cluster architecture (several nodes). Each node in the cluster has the same configuration and runs a set of processes with no single point of failure. Singleton control roles are moved between nodes on failure, implemented on a “self healing” principle. It seamlessly ties everything together as one logical warehouse/data marts and avoid locking into any data center location.

Multigraph Fuzzy Search

Artificial Intelligence / Formal Logic / Reasoning

Linked data are structured graph, so if we want to do something with, we have to enable calculus on. The graph isomorphism, subgraph isomorphism, and graph edit distance problems are combinatorial problems with many applications. Heuristic exact and approximate algorithms foreach of these problems have been developed for different kinds of graphs: directed, undirected, labeled, etc. ...
