Introduction to the Special Session

Structured patterns, such as graphs and sequences, are widely adopted to represent complex objects and

are usually semantically more related to the physical modeled pattern than a classical real valued

feature vector representation. For instance, a chemical compound, being basically composed of atoms

organized in a 3D structure, finds an intuitive representation through a labeled graph, where the

vertices represent the atoms and the edges retain their mutual spatial relations and chemical bond type.

Indeed, a labeled graph is able to encode also semantic information of the pattern, through the related

characteristic labels of both vertices and edges. For this purpose, more intuitive and well studied

examples could be made, such as segmented images, social networks, computing networks, biological

metabolic pathways, circuits, and so on. For what concerns graphs, the first key problem to deal with is

the well known Inexact Graph Matching problem. It basically consists in the definition of a suitable

(dis)similarity measure between arbitrarily-labeled graphs. Any data driven modeling system that have

to deal with graphs as input patterns must deal with this issue in order to define a proper inductive logic

inference. The same type of issues arise when dealing with sequences as input patterns of the system.

Due to the general high computational demand of these techniques and the increasing interest for large

patterns/datasets analysis, different Parallel Computing systems are employed and specialized for this

purpose.

This special session invites researchers interested in Computational Intelligence techniques for graph-

based and sequence-based Pattern Recognition and Soft Computing problems, seen also from the

Parallel Computing point of view, to propose interesting and cutting edge articles related to any aspect,

theoretical, experimental or applicative, concerning this scientific context.
