| Abstract:The "Semantic Market Monitoring" (SEMAMO) project is intended to provide
a flexible empirical instrument for the permanent collection of data -- notably, prices --
about products and services on offeneric online market observatory, SEMAMO capitalizes
on a uniform data processing scheme covering all stages from automatic data capture using
configurable mediators, through integration of Web-extracted data from multiple sources
and their long-term storage in a persistent econometric database, up to statistical analyses
feeding into flexible reporting functions. Based on a self-contained specification framework
describing formally, by means of explicit models capturing market semantics, the online
markets to be tracked, SEMAMO economizes the derivation of individual market monitoring
applications. During run-time, a SEMAMO instance then seeks to adaptively optimize data
quality and observation e±ciency based on both, previously gathered market evidence and
customer-defined reporting requirements. The framework is evaluated experimentally in a
practical application to online tourism. |
