  1. ISO-Space:Annotation of Spatial LanguageReport on Progress James Pustejovsky Brandeis University ISO Meeting, DIN, Berlin October 14, 2010

  2. Previous ISO-Space Meetings • 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. Previous ISO-Space Meetings • 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. Representation – ISO-Space • 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. Desired ISO-Space Elements • 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

  6. ISO-Space Airlie Workshop Annie Zaenen Terry Langendoen Rusty Bobrow David McDonald David Cooper Harry Bunt Jess Moszkowicz Kiyong Lee Chongwon Park Philippe Muller • Marc Verhagen • Nancy Ide • Kathleen Stewart • Christy Doran • Inderjeet Mani • Markus Schneider • Ineke Schuurman • James Pustejovsky • Beth Driver

  7. ISO-Space Airlie Workshop Anthony Cohn Mehul Bhatt Jerry Hobbs Christian Freksa Alex Klippel Thomas Bittner Joana Hois Roland Billen

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

  9. Options Discussed • 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. Breakout Focus Themes • 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. Metadata SpecificationDevelopment Cycle

  12. Requirements for Specification • 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. Results from This Workshop • List of 1st order objects in the specification • List of attributes for 1st order objects, especially Locations/regions • Determine closed classes for certain attributes • Relations • Examples for each 1st order object, annotated, including negative examples and boundary cases

  14. Results from This Workshop • New Spec will be published by November 20, 2010 • Oxford Meeting will vet current elements
