SEMAMO (SEmantic MArket MOnitoring) is a research project seeking to make use of the increasingly growing information available at Web-based sales and marketing channels for continuous market research. Assuming that online channels indeed mirror salient market developments faithfully, SEMAMO implements a nearly fully automatic adaptive data capture and analysis process delivering customer-defined market reports on demand. The paper describes the SEMAMO prototype implementation and exemplifies the functionality and utility of the approach in the domain of e-tourism, with a focus on the type of reports and visualisations the software, albeit not completely finished yet, can already deliver based on real-world data. Additionally, the role of formal domain description in SEMAMO is emphasized.
