Relation extraction

This paper addresses the problem of automatically extracting threat intelligence from unstructured text sources. We focus specifically on the possibility of multiple relations between two entities and propose a two-stage process that allows any binary classifier to be used for multiclass classification without interfering with the binary algorithm used.

This thesis documents a research program in which Australian grown Danshen extracts and related bioactive compounds have been demonstrated to be effective in scavenging free radicals, namely ROS generation, in a cell free system and NADPH oxidase derived superoxide (O2-) generation in vascular tissue (rat aorta). Danshen extracts, both aqueous and ethanol, and their active compounds (Tanshinone IIA, Salvianolic Acid B and Danshensu) demonstrated anti-oxidant activity however findings exhibited stronger activity in a cell free system than in the aortic vascular tissue.

Furthermore, experiments on the task of RE proved that data representation is one of the most influential factors to the model’s performance but still has many limitations. We propose a compositional embedding that combines several dominant linguistic as well as architectural features and dependency tree normalization techniques for generating rich representations for both words and dependency relations in the SDP

Export and Import Utilities The Export utility provides a simple way for you to transfer data objects between Oracle databases, even if they reside on platforms with different hardware and software configurations. When you run Export against an Oracle database, objects (such as tables) are extracted, followed by their related objects (such as indexes, comments, and grants), if any. The extracted data is written to an Export file, which is an Oracle binary-format dump file that is typically located on disk or tape.

Introduction: Alcohol usually means ethanol/ethyl alcohol. It has a long history for the human being, and gives euphoric effects and sometimes improves the human relationship. In contrast, there are many cases of violence, injuries, homicides and traffic accidents with drinking; close relation can be observed between ethanol and crimes/accidents. When forensic autopsies are performed, ethanol concentrations in blood and urine are routinely measured. GC analysis of ethanol using the conventional packed columns is described in many of literature [1, 2].
