This paper describes University of Illinois’s Cognitive Computation Group (UI-CCG)’s submissions for three TAC tracks: Event Nugget Detection/Coreference; Entity Discovery and Linking (EDL); and Slot Filler Validation (SFV). The Event Nugget Detection and Coreference system employs a supervised model for event nugget detection with rich lexical and semantic features while we experiment with bot...

BACKGROUND A site near Tuskegee, Alabama was examined for vector-host activities of eastern equine encephalomyelitis virus (EEEV). Land cover maps of the study site were created in ArcInfo 9.2 from QuickBird data encompassing visible and near-infrared (NIR) band information (0.45 to 0.72 microm) acquired July 15, 2008. Georeferenced mosquito and bird sampling sites, and their associated land co...

this study was conducted at beresa watershed district of guraghe administrative zone, the southern regional state of ethiopia to evaluate the on-farm reproductive and egg production performances of local kei and its f1 crosses with fayoumi and rhode island red (rir) chicken breeds under farmers’ management. the local kei paternal line was mated with maternal lines of fayoumi and rir chickens to...

An oxidative chain reaction of sulfite initiated by the superoxide ion produced in the Mehler reaction has been implicated in the damage of plants exposed to sulfur dioxide. The toxicity of SO(2) may be alleviated by free radical scavenging systems acting to terminate this chain reaction. Hence, the relative sensitivity of plants to SO(2) toxicity could depend on differences in the responses of...

The material flow and microstructural evolution in the friction stir welds of a 6061-Al alloy to itself and of a 6061-Al alloy to 2024-Al alloy plates of 12.7 mm in thickness were studied under different welding conditions. The results showed that plastic deformation, flow, and mechanical mixing of the material exhibit distinct asymmetry characteristics at both sides of the same and dissimilar ...

Ultrasonic spot welds have been used as a model system to investigate how to determine the mode-I cohesive parameters associated with interfacial fracture of a spot weld. Numerical analyses indicated that, while multiple combinations of the two cohesive parameters (characteristic strength, σ̂ , and toughness, I ) could result in virtually indistinguishable behaviors for individual geometries, on...

Actionable knowledge is a golden nugget within the data mining research field. Action rules describe possible transitions of objects in an information system from one state to another more desirable state, with respect to a distinguished attribute. In this paper we propose an improved method for generating action rules by incorporating an additional ontology layer on top of the information syst...

A steel/aluminum alloy dissimilar resistance spot welding process was simulated by a three-dimensional smoothed particle hydrodynamics method. Furthermore, the time dependent increase of intermetallic compound thickness on joining interface estimated using numerical data temperature history obtained simulation. As result, steel sheet started to melt from center in direction and formed nugget, w...
