We present a novel context pattern induction method for information extraction, specifically named entity extraction. Using this method, we extended several classes of seed entity lists into much larger high-precision lists. Using token membership in these extended lists as additional features, we improved the accuracy of a conditional random field-based named entity tagger. In contrast, featur...

The simultaneously phonological and syntactic grammar of second position clitics is an instance of the broader problem of applying constraints across multiple levels of linguistic analysis. Syntax frameworks extended with simple tree transductions can make efficient use of these necessary additional forms of structure. An analysis of Sahidic Coptic second position clitics in a context-free gram...

We present an individual based model of an abstract plant–herbivore system developed using an object oriented paradigm. The model is used to produce population time series under spatially extended and non-extended conditions and these series are subjected to spectral power analysis. The results of this analysis in respect of red and blue shifts are discussed in the context of those produced by ...

Location awareness is a crucial part of the context-awareness mechanism for ubicomputing. This paper explores how usefull is the location awareness history for an office based low-cost context-awareness environment. Capturing location awareness data into a relational database is simple and feasible in office environment. We use extended SQL to access the location awareness history database to p...

The notion of context arises in assorted areas of artificial intelligence (AI), including knowledge representation, natural language processing, intelligent information retrieval, etc. Although the term ‘context’ is frequently employed in descriptions, explanations, and analyses of computer programs in these areas, its meaning is frequently left to the reader’s understanding. In other words, it...

The notion of supply chains has been current for some time in the literature and in practice. Recently this has been extended to consider so-called extended enterprises. The paper considers extensible ontologies as a principle for integrated information and knowledge management and for knowledge sharing. Providing links between companies for the purpose of supporting extended products requires ...

We define extended conflict free dependencies in the context of functional and multivalued dependencies; and prove that there exists an acyclic, dependency preserving, 4NF database scheme if and only if the given set of dependencies has an extended conflict free cover. This condition can be checked in polynomial time. A polynomial time algorithm to obtain such a scheme for a given extended conf...

SUMMARY VistaClara is a plug-in for Cytoscape which provides a more flexible means to visualize gene and protein expression within a network context. An extended attribute browser is provided in the form of a graphical and interactive permutation matrix that resembles the heat map displays popular in gene-expression analysis. This extended browser permits a variety of display options and intera...

In this talk I review the well known relation existing between extended supersymmetry and complex geometry in the non-linear sigma-models, and then briefly discuss some recent developments related to the introduction of the nonanti-commutativity in the context of the supersymmetric non-linear sigma-models formulated in extended superspace. This contribution is suitable for both physicists and m...
