Traditional Information Extraction (IE) takes a relation name and hand-tagged examples of that relation as input. Open IE is a relationindependent extraction paradigm that is tailored to massive and heterogeneous corpora such as theWeb. An Open IE system extracts a diverse set of relational tuples from text without any relation-specific input. How is Open IE possible? We analyze a sample of Eng...

The fluctuation-dissipation relation is well known for the quantum open system with energy dissipation. In this paper a similar underlying relation is found between the bath fluctuation and the dephasing of the quantum open system, of which energy is conserved, but the information is leaking into the bath. To obtain this relation we revisit the universal, but simple dephasing model with quantum...

Traditional relation extraction seeks to identify pre-specified semantic relations within natural language text, while open Information Extraction (Open IE) takes a more general approach, and looks for a variety of relations without restriction to a fixed relation set. With this generalization comes the question, what is a relation? For example, should the more general task be restricted to rel...

We study open systems modeled as Petri nets with an interface for asynchronous communication with other open systems. As a minimal requirement for successful communication, we investigate bounded responsiveness, which guarantees that an open system and its environment always have the possibility to communicate, while the number of pending messages never exceeds a previously known bound. Bounded...

Open Information Extraction (Open IE) systems aim to obtain relation tuples with highly scalable extraction in portable across domain by identifying a variety of relation phrases and their arguments in arbitrary sentences. The first generation of Open IE learns linear chain models based on unlexicalized features such as Part-of-Speech (POS) or shallow tags to label the intermediate words betwee...

background: glaucoma is a progressive optic neuropathy and is one of the leading causes of blindness worldwide. different factors have been contributed in the pathogenesis of glaucoma including h. pylori infection. objective: to determine the levels of anti-h. pylori igg antibody in the aqueous humor of patients with pseudoexfoliation and primary open angle glaucoma, in comparison with age and ...
