Graph has been widely adopted to model complex networks in nature and human society. Community structures, as functional building blocks, exist in many real-world networks, for example, social networks and biological networks. Thus, mining and querying community structure in massive networks is of ...

query construction, query ranking and answer decision. In the first step, all possible entities, properties and classes in the question are identified through lexicalization. Then, a set of queries is constructed based on the combinations of the previously identified entities, properties and classes i...
optimized scans of vector data that is not chunked into blocks. Second, tree-based index structures like the ones mentioned above incur overhead in space and time complexity because an index itself needs to be managed. In particular, nodes in these tree structures are linked in support of ...
Research and education through computer simulation has been actively conducted in various scientific and engineering fields including computational science engineering. Accordingly, there have been a lot of attentions paid to actively utilize provenance
We present and demonstrate a querying approach of converting Object-Process Methodology (OPM) ISO 19450 models into graphs, storing them in a Neo4J graph database, and performing queries that answer complex questions on various system aspects, providing key insights into the modeled system or ...
