RelSim: Relation Similarity Search in Schema-Rich Heterogeneous Information Networks
TL;DR: A new meta-path-based relation similarity measure, RelSim, is defined, to measure the similarity between relation instances in schema-rich HINs, and an optimization model is proposed to efficiently learn LSR implied in the query through linear programming.

Warehousing and mining massive RFID data sets
TL;DR: In this article, the authors propose two data models for the management of RFID data, a path cube that preserves object transition information while allowing muti-dimensional analysis of path dependent aggregates and a workflow cube that summarizes the major patterns and significant exceptions in the flow of items through the system.
Proceedings ArticleDOI
Inferring human mobility patterns from taxicab location traces
TL;DR: It is shown that while past approaches are effective in detecting hotspots using location traces, they are largely ineffective in identifying trips (pairs of pickup and dropoff points) and proposed the use of a graph theory concept - stretch factor in a novel manner to identify trip(s) made by a taxicab.
Proceedings ArticleDOI
Node, motif and subgraph: leveraging network functional blocks through structural convolution
TL;DR: NEST is developed, a novel hierarchical network embedding method combining motif filtering and convolutional neural networks that enables NEST to capture exact small structures within networks, and convolved embedding allows it to fully explore complex substructures and their combinations.
