In this paper we present a simplified shallow semantic parsing approach to learning the scope of negation (SoN). This is done by formulating it as a shallow semantic parsing problem with the negation signal as the predicate and the negation scope as its arguments. Our parsing approach to SoN learning differs from the state-of-the-art chunking ones in two(More)
Chiang's hierarchical phrase-based (HPB) translation model advances the state-of-the-art in statistical machine translation by expanding conventional phrases to hierarchical phrases – phrases that contain sub-phrases. However , the original HPB model is prone to over-generation due to lack of linguistic knowledge: the grammar may suggest more derivations(More)
This paper explores Chinese semantic role labeling (SRL) for nominal predicates. Besides those widely used features in verbal SRL, various nominal SRL-specific features are first included. Then, we improve the performance of nominal SRL by integrating useful features derived from a state-of-the-art verbal SRL system. Finally, we address the issue of(More)
There is increasing evidence that hepatocellular carcinoma (HCC) is inherently associated with the inflammatory process and the up-regulation of cytokines. Our study aimed at elucidating the role of the cytokine fractalkine in the process of HCC carcinogenesis. Expression of fractalkine in hepatocellular carcinoma cell line HepG2 was knocked-down by RNAi.(More)
Cotton is one of the important oil crops, and it is great significance for screening and identification of breeding materials to establish a method of the rapid, nondestructive testing of cotton seed oil content. In this study, near-infrared diffuse reflection spectroscopy of 118 high and low oil materials were adopted to establish models for fast(More)
This paper describes the submitted En-glish shallow discourse parsing system from the natural language processing (NLP) group of Soochow university (SoNLP-DP) to the CoNLL-2016 shared task. Our System classifies discourse relations into explicit and non-explicit relations and uses a pipeline platform to conduct every subtask to form an end-to-end shallow(More)
This study aimed to explore the causes, incidence, and risk factors of urinary tract infection patients in neurological intensive care unit (ICU). Patients (n = 916) admitted to the neurological ICU from January 2005 to December 2010 were retrospectively surveyed for urinary tract infections. There were 246 patients in neurological ICU who were diagnosed(More)
OBJECTIVE To investigate the surgical techniques and effectiveness for reconstruction of severe full-thickness chest wall defects. METHODS Between January 2006 and December 2010, 14 patients with full-thickness chest wall defects were treated, including 12 cases caused by giant chest wall malignant tumor excision, 1 case by thermocompression injury, and 1(More)
OBJECTIVE To perform a systematic review and meta-analysis regarding the efficacy and safety of dipeptidyl peptidase-4 (DDP-4) inhibitors ("gliptins") for the treatment of type 2 diabetes mellitus (T2DM) patients with moderate to severe renal impairment. METHODS All available randomized-controlled trials (RCTs) that assessed the efficacy and safety of(More)
The SCF/c-kit signaling plays an important role in invasion of c-kit-expressing tumor cells, however, the molecular mechanisms have not been studied yet. Using a pancreatic cancer model, we demonstrate that SCF/c-kit binding up-regulates the expression of invasion-related genes through the accumulation of HIF-1α. Furthermore, the expression of HIF-1α(More)
