Query: HetNetAligner: Design and Implementation of an algorithm for
  heterogeneous network alignment on Apache Spark   The importance of the use of networks to model and analyse biological data
and the interplay of bio-molecules is widely recognised. Consequently, many
algorithms for the analysis and the comparison of networks (such as alignment
algorithms) have been developed in the past. Recently, many different
approaches tried to integrate into a single model the interplay of different
molecules, such as genes, transcription factors and microRNAs. A possible
formalism to model such scenario comes from node coloured networks (or
heterogeneous networks) implemented as node/ edge-coloured graphs.
Consequently, the need for the introduction of alignment algorithms able to
analyse heterogeneous networks arises. To the best of our knowledge, all the
existing algorithms are not able to mine heterogeneous networks. We propose a
two-step alignment strategy that receives as input two heterogeneous networks
(node-coloured graphs) and a similarity function among nodes of two networks
extending the previous formulations. We first build a single alignment graph.
Then we mine this graph extracting relevant subgraphs. Despite this simple
approach, the analysis of such networks relies on graph and subgraph
isomorphism and the size of the data is still growing. Therefore the use of
high-performance data analytics framework is needed. We here present
HetNetAligner a framework built on top of Apache Spark. We also implemented our
algorithm, and we tested it on some selected heterogeneous biological networks.
Preliminary results confirm that our method may extract relevant knowledge from
biological data reducing the computational time.
