Background: Increasing evidence from recent studies has revealed the association of CA125 with the diagnosis of pancreatic cancer, but inconsistent findings have been reported. We aimed to evaluate the diagnostic value of a serum CA125-based diagnostic panel in predicting malignant pancreatic cancer. Materials and Methods: We searched EMBASE, MEDLINE and Web of Science for relevant articles fro...

Recent evaluation techniques applied to corpusbased systems have been introduced that can predict quantitatively how well surface realizers will generate unseen sentences in isolation. We introduce a similar method for determining the coverage on the Fuf/Surge symbolic surface realizer, report that its coverage and accuracy on the Penn TreeBank is higher than that of a similar statistics-based ...

We describe and analyze the surprising evolution of an overflow error which has occurred during the simulation of a class of continuous complex systems called ‘fuzzy cellular automata’. This error not only perturbs the global behavior of the system but it generates its own interesting dynamics; in fact, it propagates over the original evolution as a binary cellular automaton in a structured, fr...

We present a search-based approach to automatic surface realization given a corpus of domain sentences. Using heuristic search based on a statistical language model and a structure we introduce called an inheritance table we overgenerate a set of complete syntactic-semantic trees that are consistent with the given semantic structure and have high likelihood relative to the language model. These...

An effective field theory with hadrons and photons is constructed, where the hadronic parameters are determined by fitting elastic πN scattering data. The predicted pioninduced η-production on the nucleon agrees well with the data. The hadronic model is then used to describe the final-state interaction in photoinduced processes. We present a consistent description of pion photoproduction in the...

This paper describes the linguistic part of a system called PROVERB, which transforms, abstracts, and verbalizes machine-found proofs into formated texts. Linguistically, the architecture of PROVERB follows most application oriented systems, and is a pipe-lined control of three components. Its macroplanner linearizes a proof and plans mediating communicative acts by employing a combination of h...

This paper describes Acorn, a sentence planner and surface realizer for dialogue systems. Improvements to previous stochastic word-forest based approaches are described, countering recent criticism of this class of algorithms for their slow speed. An evaluation of the approach with semantic input shows runtimes of a fraction of a second and presents results that suggest it is also portable acro...

The evolution of the job market has resulted in traditional methods of recruitment becoming insu cient. As it is now necessary to handle volumes of information (mostly in the form of free text) that are impossible to process manually, an analysis and assisted categorization are essential to address this issue. In this paper, we present a combination of the E-Gen and Cortex systems. E-Gen aims t...

Building a complete virtual human application from scratch is a daunting task, and it makes sense to rely on existing platforms for behavior generation. When building such an interactive application, one needs to be able to adapt and extend the capabilities of the virtual human offered by the platform, without having to make invasive modifications to the platform itself. This paper describes ho...
