Generating Relation Algebras for Qualitative Spatial Reasoning

Basic relationships between certain regions of space are formulated in natural language in everyday situations. For example, a customer specifies the outline of his future home to the architect by indicating which rooms should be close to each other. Qualitative spatial reasoning as an area of artificial intelligence tries to develop a theory of space based on similar notions. In formal ontology and in ontological computer science, mereotopology is a first-order theory, embodying mereological and topological concepts, of the relations among wholes, parts, parts of parts, and the boundaries between parts. We shall introduce abstract relation algebras and present their structural properties as well as their connection to algebras of binary relations. This will be followed by details of the expressiveness of algebras of relations for region based models. Mereotopology has been the main basis for most region based theories of space. Since its earliest inception many theories have been proposed for mereotopology in artificial intelligence among which Region Connection Calculus is most prominent. The expressiveness of the region connection calculus in relational logic is far greater than its original eight base relations might suggest. In the thesis we formulate ways to automatically generate representable relation algebras using spatial data based on region connection calculus. The generation of new algebras is a two pronged approach involving splitting of existing relations to form new algebras and refinement of such newly generated algebras. We present an implementation of a system for automating aforementioned steps and provide an effective and convenient interface to define new spatial relations and generate representable relational algebras.

Laura Dexter letter, commenting on the McLeod murder trial, October 5, 1841

Alexander McLeod was Deputy Sheriff of the Niagara District during the Rebellion of 1837-38 in Upper Canada. On December 24, 1837, he became aware of a scheme by the rebels to use the American steamboat Caroline to provide supplies to William Lyon Mackenzie and his followers on Navy Island in the Niagara River. McLeod notified the authorities in Upper Canada about the situation. A few days later, on December 29, Commodore Andrew Drew led a band of men, including McLeod, to the American side, where the Caroline was moored at Schlosser’s Wharf. A scuffle ensued, in which American Amos Durfee was killed. The Caroline was then released from its moorings, set on fire, and drifted downstream before sinking. Many Americans viewed the incident as a violation of their sovereignty. Tensions between the United States and England were already strained over a boundary dispute between Maine and New Brunswick, and the situation with the Caroline further escalated the tension. McLeod was subsequently arrested in November, 1840 in Lewiston, NY and indicted for arson and murder. The British foreign secretary, Lord Palmerston, insisted that McLeod be released and could not be held personally responsible for the incident, as he was acting on orders from authorities in Canada. Eventually, McLeod was acquitted.
