Leveraging Pyramids
نویسندگان
چکیده
The Pyramid system associates importance ratings with individual sentences in evaluated summaries. Given that many summarization systems compose their output from source document sentences with limited or no editing, it is often possible to propagate Pyramid ratings back to the source document and tag source sentences with one measure of their suitability to a generic summary. In the case of Pyramid evaluations of summaries of twenty topics in DUC 2005, this could be done in sufficiently many instances to make the effort worthwhile: 14% of nineteen thousand source document sentences were annotated with importance ratings.

Pyramids of n-Dimensional Generalized Maps
Graph pyramids are often used for representing irregular pyramids. Combinatorial pyramids have been recently defined for this purpose. We define here pyramids of n-dimensional generalized maps. This is the main contribution of this work: a generic definition in any dimension which extend and generalize the previous works. Moreover, such pyramids explicitly represent more topological information...
متن کاملNeural Networks versus Image
Neural networks and image pyramids are massively parallel processing structures. In this paper we exploit the similarities as well as the diierences between these structures. The general goal is to exchange knowledge between these two elds. After introducing the basic concepts of neural networks and image pyramids we give a translation table of the vocabulary used in image pyramids and those us...
متن کاملThe effect of pyramids on preservation of milk
Pyramid has been variously studied for its mystical preservative, healing and curative effects. The power of the pyramids has been much talked about in Egypt and the great pyramids as the wonders of the world. They are mentioned as çikhariëis and gopurams used in temples in Indian tradition. It is associated with Chakras and the elevation of the human mind to the super-consciousness levels. Alt...
متن کاملA First Step toward Combinatorial Pyramids in n-D Spaces
Combinatorial maps define a general framework which allows to encode any subdivision of an nD orientable quasi-manifold with or without boundaries. Combinatorial pyramids are defined as stacks of successively reduced combinatorial maps. Such pyramids provide a rich framework which allows to encode fine properties of the objects (either shapes or partitions). Combinatorial pyramids have first be...
