Extending, trimming and fusing WordNet for technical documents

This paper describes a tool for the automatic extension and trimming of a multilingual WordNet database for cross-lingual retrieval and multilingual ontology building in intranets and domain-specific document collections. Hierarchies, built from automatically extracted terms and combined with the WordNet relations, are trimmed with a disambiguation method based on the document salience of the words in the glosses. The disambiguation is tested in a cross-lingual retrieval task, showing considerable improvement (7%-11%). The condensed hierarchies can be used as browse-interfaces to the documents complementary to retrieval

Cost Accounting and Pricing Improvement at Helmond Print: Using Xeikon Digital Colour Printing Equipment: A Case study

Helmond Print B.V., a (fictional) Dutch print provider, is facing competitive problems. The student is expected to step into the role of an independent expert advising Helmond Print''s owner and manager. The first objective is to let the student find out, from a piece of qualitative and quantitative information about Xeikon N.V. machines, that the cost structure is much different than currently assumed. The student should try to improve the cost calculations, which will require linear and both non-linear regression analysis. A second objective is to make the student realize that the incorrect cost calculations affected Helmond Print''s pricing policy and may have lead to the competitive problems faced now. The student should therefore link their investigations to pricing, search for the weak spots in the current pricing policy and make suggestions for improvement. (Note: a solution to the case can be obtained by simple request)management and organization theory ;

Automatic sense clustering in EuroWordNet

This paper addresses ways in which we envisage to reduce the fine-grainedness of WordNet and express in a more systematic way the relations between its numerous sense distinctions. In the EuroWordNet project, we have distinguished various automatic methods for grouping senses into more coarse-grained sense groups. These resulting clusters reflect aspects of lexical organization, displaying a variety of semantic regularities or generalizations. In this way, the compatibility of the language-specific wordnets in the EuroWordNet multilingual knowledge base is increased

Topologically non-trivial quantum layers

Given a complete non-compact surface embedded in R^3, we consider the Dirichlet Laplacian in a layer of constant width about the surface. Using an intrinsic approach to the layer geometry, we generalise the spectral results of an original paper by Duclos et al. to the situation when the surface does not possess poles. This enables us to consider topologically more complicated layers and state new spectral results. In particular, we are interested in layers built over surfaces with handles or several cylindrically symmetric ends. We also discuss more general regions obtained by compact deformations of certain layers.Comment: 15 pages, 6 figure

The Multilingual design of the EuroWordNet Database

This paper discusses the design of the EuroWordNet database, in which semantic databases like WordNet1.5 for several languages are combined via an inter-lingua. In this database, language-independent data is shared and language-specific properties are maintained as well. A special interface has been developed to compare the semantic configurations across languages and to track down differences. The pragmatic design of the database makes it possible to gather empirical evidence for a common cross-linguistic ontology. Abstract This paper discusses the design of the EuroWordNet database, in which semantic databases like WordNet1.5 for several languages are combined via a so-called interlingual -index. In this database, languageindependent data is shared and languagespecific properties are maintained as well. A special interface has been developed to compare the semantic configurations across languages and to track down differences. The pragmatic design of the database makes it possible..

Bash Cookbook

The key to mastering any Unix system, especially Linux and Mac OS X, is a thorough knowledge of shell scripting. Scripting is a way to harness and customize the power of any Unix system, and it's an essential skill for any Unix users, including system administrators and professional OS X developers. But beneath this simple promise lies a treacherous ocean of variations in Unix commands and standards.bash Cookbook teaches shell scripting the way Unix masters practice the craft. It presents a variety of recipes and tricks for all levels of shell programmers so that anyone can become a proficien
