Koskenniemi’s two-level morphological analysis system can be improved upon by using a PATR-like unification grammar for handling the morphosyntax instead of continuation classes, and by incorporating the notion of negative rule feature into the phonological rule interpreter.
The SLICE textured-image segmentation system identifies image regions that differ in gray-level distribution, color, spatial texture, or other local property.
This paper is an informal survey of models of grammatical categories in unification-based formalisms from computational linguistics and their relationship to current logic programming concepts.
Objective: To conduct a research study and experimental investigation of techniques and equipment characteristics suitable for practical application to graphical data processing for military requirements.
We have substantially expanded the capabilities of the data base access component that serves as the interface between the natural-language front end of LADDER and the data base management systems on which the data is actually stored.
There is considerable ambiguity involved in hierarchical planning. We present a definition of the latter, and examine several of the reasons for this confusion.
We present a formalism for the computer representation of three-dimensional shapes, that has as its goal to facilitate man-machine communication using verbal, graphic, and visual means. With this method, pieces may be assembled hierarchically using any of several ways of specifying attachment.
This paper describes a new technique for use in the automatic production of digital terrain models from stereo pairs of aerial images. This technique employs a coarse-to-fine hierarchical control structure both for global constraint propagation and for efficiency.
