ing symbolic matrices Special issue on artificial intelligence and symbolic computation Randa Almomen · Alan P. Sexton · Volker Sorge © Springer Science+Business Media B.V. 2012 Abstract We present a procedure that allows the abstraction of elements in concrete symbolic matrices to obtain a more compact representation employing ellipses in order to expose homogeneous regions present in a matrix...

Many high level representations of time series have been proposed for data mining. One representation that the data mining community has not considered in detail is the discretization of the original data into symbolic strings. At first glance this seems a surprising oversight. There is an enormous wealth of existing algorithms and data structures that allow the efficient manipulations of strin...

We propose an algorithm, MusicBLAST, for approximate pattern search/matching on symbolic musical data. MusicBLAST is based on the BLAST algorithm, one of the most commonly used algorithms for similarity search on biological sequence data [1, 2]. MusicBLAST can be used in combination with an arbitrary similarity measure (e.g., melodic, rhythmic or combined) and retrieves multiple occurrences of ...

The performance of (bio-)signal classification strongly depends on the choice of suitable features (also called parameters or biomarkers). In this article we evaluate the discriminative power of ordinal pattern statistics and symbolic dynamics in comparison with established heart rate variability parameters applied to beat-to-beat intervals. As an illustrative example we distinguish patients su...

The suitability of the BPEL workflow description language for the dynamic composition of Web services representing computational algebra systems is investigated. The prototype implementation of the system for dynamic generation of BPEL workflows and two examples demonstrating the benefits of our approach are described. One of important aspects of the design is that the composition is achieved u...

The old workhorse called linearity of expectation, by which it is often very easy to compute the expectation (alias first moment) of interesting combinatorial quantities, can also be used to compute higher moments, as well as correlations, but then things get very soon too complicated for mere humans. The computer, used as a symbol-cruncher, can go much further (alas, only by a few orders of ma...

Examining the planning of cemeteries in the urbanism system of Iran does not show a goodcondition. In fact, cemeteries in the most Persian cities have become large-scale open spaces outside the city. This couldcause irreparable damage to the cities because of the partial and/or improper use of the capacity of urban lands. Alongwith this, historical cemeteries within the cities have been abandon...
