Generating Aspect-oriented Multi-Document Summarization with Event-aspect model
In this paper, we propose a novel approach to automatic generation of aspect-oriented summaries from multiple documents. We first develop an event-aspect LDA model to cluster sen...

Lossless Compression of Satellite Image Sets Using Spatial Area Overlap Compensation
Abstract. In this paper we present a new prediction technique to compress a pair of satellite images that have significant overlap in the underlying spatial areas. When this predi...

Automata on Lempel-ziv Compressed Strings
Using the Lempel-Ziv-78 compression algorithm to compress a string yields a dictionary of substrings, i.e. an edge-labelled tree with an order-compatible enumeration, here called a...
