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...

Beware of the DAG!

Directed acyclic graph (DAG) models are popular tools for describing causal relationships and for guiding attempts to learn them from data. In particular, they appear to supply a means of extracting causal conclusions from probabilistic conditional independence properties inferred from purely observational data. I take a critical look at this enterprise, and suggest that it is in need of more, ...

Fire fighter deaths from tanker truck rollovers.

Mobile water supply vehicles, known as tankers or tenders, are widely used to transport water to areas beyond a water supply system or where the water supply is inadequate. Incidents in­ volving motor vehicles account for approximately 20% of U.S. fire fighter deaths each year; cases involving tankers are the most prevalent of these motor vehicle incidents. During 1977–1999, 73 deaths occurred ...
