We describe a method for the automatic extraction of a Stochastic Lexicalized Tree Insertion Grammar from a linguistically rich HPSG Treebank. The extraction method is strongly guided by HPSG–based head and argument decomposition rules. The tree anchors correspond to lexical labels encoding fine–grained information. The approach has been tested with a German corpus achieving a labeled recall of...
A quick, simple and improved DNA extraction method from polysaccharide rich leaves of Boswellia serrata Roxb. has been developed. Different methods involving use of CTAB and SDS with or without modification were used. A CTAB based extraction method which uses diatomite to remove polysaccharides, such as, gums and resin, proved to be the best. This method allowed recovery of good quality DNA in ...
The extraction of membrane tubes by molecular motors is known to play an important role for the transport properties of eukaryotic cells. By studying a generic class of models for the tube extraction, we discover a rich phase diagram. In particular we show that the density of motors along the tube can exhibit shocks, inverse shocks and plateaux, depending on parameters which could in principle ...

BACKGROUND The text descriptions in electronic medical records are a rich source of information. We have developed a Health Information Text Extraction (HITEx) tool and used it to extract key findings for a research study on airways disease. METHODS The principal diagnosis, co-morbidity and smoking status extracted by HITEx from a set of 150 discharge summaries were compared to an expert-gene...
Data extraction is a necessary technology to deal with the huge and growing collection of unstructured and semistructured information available on the World Wide Web. Ontology-based data extraction is a robust approach, but the construction of ontologies is a technical task requiring the services of a human expert. We present a Java-based tool for the graphical creation and testing of data extr...
This study proposes to employ syntactic and semantic knowledge from the rich relations within a tree kernel structure for relation extraction. The underlying idea is that different tree kernels with a variety of representations of the available linguistic information will improve the performance of detecting useful pieces of information expressed in a sentence. Applying clause-based rules, clus...
A greener method based on cloud point extraction was developed for removing phenol species including 2,4-dichlorophenol (2,4-DCP), 2,4,6-trichlorophenol (2,4,6-TCP) and 4-nitrophenol (4-NP) in water samples by using the UV-Vis spectrophotometric method. The non-ionic surfactant DC193C was chosen as an extraction solvent due to its low water content in a surfactant rich phase and it is well-know...
A new, cost-effective, and environmental-friendly cloud point extraction methodology was described for enrichment of copper, manganese and nickel in several water samples. The method involves the complexation of copper, manganese or nickel with 2-amino-6-(1,3-thiazol-2-diazeyl)-phenol at pH 7.0, then extraction into Triton X-114. After dilution of the surfactant-rich phase with acidified methan...
