Vold i dag: En kort introduktion

Ord i Dag: Mining Norwegian Daily Newswire

We present Ord i Dag, a new service that displays today's most important keywords. These are extracted fully automatically from Norwegian online newspapers. Describing the complete process, we provide an entirely disclosed method for media monitoring and news summarization. For keyword extraction, a reference corpus serves as background about average language use, which is contrasted with the c...

On maximum spanning DAG algorithms for semantic DAG parsing

Consideration of the decoding problem in semantic parsing as finding a maximum spanning DAG of a weighted directed graph carries many complexities that haven’t been fully addressed in the literature to date, among which are its actual appropriateness for the decoding task in semantic parsing, not to mention an explicit proof of its complexity (and its approximability). In this paper, we conside...

The Vold-Sutherland and Eden Models of Cluster Formation 1

Large clusters or flocs have been grown on the computer using the models introduced by Void and Sutherland and by Eden. Some of the properties of these dusters have been analyzed and compared with the same properties of dusters grown using the diffusion limited growth process of Witten and Sander. For all three models the radius of gyration (Rg) is related to the number of particles in the dust...

Characteristics of the Vold-Kalman order tracking filter

In this paper the filter characteristics of the Vold-Kalman Order Tracking Filter are presented. Both frequency response as well as time response and their time-frequency relationship have been investigated. Some guidelines for optimum choice of filter parameters are presented. The Vold-Kalman filter allows for the high performance simultaneous tracking of orders in systems with multiple indepe...
