Design and implementation of a framework for geoprofile-driven content enrichment and data quality improvement on the basis of user-volunteered content and open spatial data services. Background: The domain-of-activity is often the catalyst in the formation of a societal network, but standardized approaches to their IT support are inadequate. The where-and-when of network member activity is a dominating information factor, and its proper characterization (in geoprofiles) allows to optimize communication between the members.
Description of work
This WP aims to provide a toolset for building support systems for a networked community whose members display similar activities in similar locations and want to share raw multimedia content, valuations and experiences about those. Scientific challenges encountered include geo-referenced entity resolution, automatic data integration for content enrichment, information extraction, data quality improvement, uncertainty management and data quality improvement, domain-of-activity specification, understanding user activities and routes (geoprofiling), and geo-data processing. An XML-based ETL- architecture will be developed which is based on a spatially enhanced XML DBMS and which includes a toolset to provide for development support with the above challenges from user-volunteered content.
Two demonstrators are developed in this context:
- EuroCottage portal improvement for community building and holiday home location profiling and
- international development collaboration in agriculture.
The first is developed in stages: we first focus on content enrichment for the EuroCottage portal for early dissemination purposes and as a basis for a later geoprofile-driven enhancements. Furthermore, we also plan to quickly develop a EuroCottage holiday mash-up service to attract and gather user-volunteered content to be used for the geoprofiling research and validation. The second is developed in year 4 as an additional demonstrator to increase general impact and dissemination and to validate domain flexibility.
