Abstract:
In our days knowledge extraction methods are able to
produce artifacts (also called patterns) that concisely rep-
resent data. Patterns are usually quite heterogeneous and
require ad-hoc processing techniques. So far, little empha-
sis has been posed on developing an overall integrated en-
vironment for uniformly representing and querying dif-
ferent types of patterns. Within the larger context of mod-
elling, storing, and querying patterns, in this paper, we:
(a) formally de¯ne the logical foundations for the global
setting of pattern management through a model that cov-
ers data, patterns and their intermediate mappings; (b)
present a pattern speci¯cation language for pattern man-
agement along with safety restrictions; and (c) intro-
duce queries and query operators and identify interest-
ing query classes.
