Recursive Construction of Granular Route Directions
نویسندگان
چکیده
Familiar wayfinders communicate route directions in a granular manner. In contrast to current navigation services, the detail of the description is adapted to the relation between the start and the target of the route. References to elements of the city are select in a manner leading to a referring expression respecting the conversation maxims formulated by Paul Grice (1975, 1989). We demonstrate how a granular route directions can be reconstructed based on the selection of appropriate elements of the city from a hierarchical city structure, and we argue that the process is based on a recursive application of a small set of topological

Identification of the Initial Entity in Granular Route Directions
Current navigation services assume wayfinders new to an environment. In contrast, our focus is on route directions for wayfinders who are familiar with the environment, such as taxi drivers and couriers. We observe that people communicate route directions to these wayfinders in a hierarchical and granular manner, assuming some shared knowledge of the environment. These route directions do not f...
متن کاملA recursive construction of a class of finite normalized tight frames
Finite normalized tight frames are interesting because they provide decompositions in applications and some physical interpretations. In this article, we give a recursive method for constructing them.
متن کاملPragmatic Construction of Destination Descriptions for Urban Environments
Destination descriptions are route descriptions focusing on the ‘where’ of the destination instead of the ‘how’ to reach it. They provide first a coarse reference to the destination, and then increasingly more detailed ones as the description proceeds. In this paper, we introduce a definition of destination descriptions, along with an analysis of the construction and interpretation of destinati...

متن کاملA New Attribute Reduction Recursive Algorithm Based On Granular Computing
Existing representative research achievement of attribute reduction mainly focused on two aspects. One is how to improve the efficiency of attribute reduction algorithms for all attributes including the added properties. Such as the recursive algorithm to change conjunctive normal form into disjunctive normal form based on the Boolean matrix and algorithm based on radix sorting for computing co...
