1. ISO-S PACE : A NNOTATION OF S PATIAL L ANGUAGE R EPORT ON P ROGRESS James Pustejovsky Brandeis University ISO Meeting, DIN, Berlin October 14, 2010

2. P REVIOUS ISO-S PACE M EETINGS May 31, 2009 NACCL, Boulder Announcing ISO-Space as a Working Item (WI) Initial Requirements defined Nov. 3, 2009, Brandeis Requirements vetted and critiqued Motion and Paths are added to Requirements

3. P REVIOUS ISO-S PACE M EETINGS March 29-April 1, 2010, Dagstuhl Reification of Events as Spatial Entities Incorporating QSR elements into requirements for ISO-Space September 26-29, 2010, Airlie House, VA Progress on Spec 1.3 Diverse Genres studied Intense Discussion on Spec Elements

4. R EPRESENTATION – ISO-S PACE Goals: Building a spatial map of objects relative to each other. Reconstructing spatial information associated with a sequence of events. Determining object location given a verbal description. Translating viewer-centric verbal descriptions into other relative descriptions or absolute coordinate descriptions. Constructing a route given a route description Constructing a spatial model of an interior or exterior space given a verbal description. Integrating spatial descriptions with information from other media

5. D ESIRED ISO-S PACE E LEMENTS Regions – Geographic, Geopolitical Places, Functional Locations – Arbitrary Locations Entities as Spatial Objects – intrinsic orientation, dimensionality, size, shape Path Objects – routes, lines, turns, arcs Links – Topological relations – Dimension and Orientation – Metrics Spatial Functions – behind the building, twenty miles from Boulder Movements and Spatial Processes – functions from regions to regions

8. I SSUES A DDRESSED 1. How do we provide for an expressive vocabulary of regions and shapes of objects? 2. Do we need a distinction between location, place, and region? 3. How do we encode orientation, direction, and frame of reference? 4. What is the treatment of motion in spatiotemporal markup? 5. How should qualitative relations between regions be represented? 6. What is the set of relations necessary for this purpose? 7. How explicit should the representation of paths be in movement? 8. How do we locate events in space? 9. How should the language link to GIS databases and resources? 10. What elements of existing resources, such as GML and SpatialML,can and should incorporated?

9. O PTIONS D ISCUSSED Varying Functional specifications of ISO-Space : Distance as 1st class object Paths as 1st class object S_Functions are dropped or enhanced Locations vs places … Determining needs from GIS and QSR communities Annotation of different texts according to specs

10. B REAKOUT F OCUS T HEMES Relatively easy to annotate expressions Difficult or unclear how to annotate expressions Object properties Paths: types, attributes, What to do with Events Place/location/region distinction Vagueness

11. M ETADATA S PECIFICATION D EVELOPMENT C YCLE

12. R EQUIREMENTS FOR S PECIFICATION Guidelines are complete and transparent The annotation task is the appropriate level of complexity High inter-annotator agreement Satisfy descriptive adequacy Allows for a clear compositional semantics

13. R ESULTS FROM T HIS W ORKSHOP List of 1 st order objects in the specification List of attributes for 1 st order objects, especially Locations/regions Determine closed classes for certain attributes Relations Examples for each 1 st order object, annotated, including negative examples and boundary cases

14. R ESULTS FROM T HIS W ORKSHOP New Spec will be published by November 20, 2010 Oxford Meeting will vet current elements
