What are Spatial Objects?

Does 80% of all data have a spatial component? What is spatiality anyway? Real geographic modelling is often not as sweet (DOLCE) as it should be. Mashups are taking over the world; why do we love them so much? And why are they so boring? We try to answer these questions by formulating what a spatial object is relatively to a given context. Further interrogations include: affordances, why do we need them? is multi-representation useful and sound? who will win the semantic web challenge? By integrating this model with Semantic Web Services, supported by IRS-III as an execution platform, and OCML ontologies as a knowledge model, we try to answer those and believe that the availability and usefulness of spatially related data can be radically improved.

Multimedia and Information Systems
Our research is centred around the theme of Multimedia Information Retrieval, ie, Video Search Engines, Image Databases, Spoken Document Retrieval, Music Retrieval, Query Languages and Query Mediation.

We focus on content-based information retrieval over a wide range of data spanning form unstructured text and unlabelled images over spoken documents and music to videos. This encompasses the modelling of human perception of relevance and similarity, the learning from user actions and the up-to-date presentation of information. Currently we are building a research version of an integrated multimedia information retrieval system MIR to be used as a research prototype. We aim for a system that understands the user's information need and successfully links it to the appropriate information sources, be it a report or a TV news clip. This work is guided by the vision that an automated knowledge extraction system ultimately empowers people making efficient use of information sources without the burden of filing data into specialised databases.
