In this paper, we present Kathaa1, an open source web based Visual Programming Framework for NLP applications. It supports design, execution and analysis of complex NLP systems by choosing and visually connecting NLP modules from an already available and easily extensible Module library. It models NLP systems as a Directed Acyclic Graph of optionally parallalized information flow, and lets the ...

Natural language processing (NLP) is gradually becoming a more multidisciplinary field, and research in remotely connected aspects of language such as paralinguistic phonetics may benefit from as well as contribute to some areas of NLP. This paper provides a brief overview of paralinguistic phonetics, and some current NLPrelated methods and models used in TTS and ASR systems today. In order to ...

NLP-NG is a new NLP system consisting of three components: NG-CORE (language processing), NG-DB (database management), and NG-SEE (interactive visualization and entry). The ultimate goal of NLP-NG is to produce information retrieval systems in which users can choose full-text schema, adding specific items to focus their queries. Schema are created by a normalization process which elides adjunct...

Natural languages are characterized by rich relational structures and tight integration with world knowledge. As the field of NLP/CL moves towards more complex and challenging tasks, there has been increasing interest in applying joint inference to leverage such relations and prior knowledge. Recent work in statistical relational learning (a.k.a. structured prediction) has shown that joint infe...

In this paper, we present the meta-tooling framework named TAISim that can be used both as a developer‟s tool for creating NLP systems and as a NLP learning environment, which allows helping students to construct NLP systems by example in a flexible way. TAISim enables the end user to combine different components of a typical NLP system in order to tackle specific NLP problems. We use ontology-...

Trypanosoma brucei mono-allelically expresses one of approximately 1500 variant surface glycoprotein (VSG) genes while multiplying in the mammalian bloodstream. The active VSG is transcribed by RNA polymerase I in one of approximately 15 telomeric VSG expression sites (ESs). T. brucei is unusual in controlling gene expression predominantly post-transcriptionally, and how ESs are mono-allelicall...

It is commonly accepted that machine translation is a more complex task than part of speech tagging. But how much more complex? In this paper we make an attempt to develop a general framework and methodology for computing the informational and/or processing complexity of NLP applications and tasks. We define a universal framework akin to a Turning Machine that attempts to fit (most) NLP tasks i...

1. Abstract The imact of NLP on information retrieval tasks has largely been one of promise rather than substance. While there are exceptions to this as some of the chapters in the present volume demonstrate, for the most part NLP and information retrieval have only recently started to dovetail together. In this chapter we will present a pr ecis of our experiments in information retrieval using...

The application of Natural Language Processing (NLP) methods and resources to clinical and biomedical text has received growing attention over the past years, but progress has been limited by difficulties to access shared tools and resources, partially caused by patient privacy and data confidentiality constraints. Efforts to increase sharing and interoperability of the few existing resources a...

This study examines the biology of NLP-12 neuropeptides in Caenorhabditis elegans, and in the parasitic nematodes Ascaris suum and Trichostrongylus colubriformis. DYRPLQFamide (1 nM-10 microM; n > or =6) produced contraction of innervated dorsal and ventral Ascaris body wall muscle preparations (10 microM, 6.8+/-1.9 g; 1 microM, 4.6+/-1.8 g; 0.1 microM, 4.1+/-2.0 g; 10 nM, 3.8+/-2.0 g; n > or =...
