Using Kaleidographic to visualize multimodal relations within and across texts

Extracting Relations Within and Across Sentences

Previous work on relation extraction has focussed on identifying relationships between entities that occur in the same sentence (intra-sentential relations) rather than between entities in different sentences (inter-sentential relations) despite previous research having shown that intersentential relations commonly occur in information extraction corpora. This paper describes a SVM-based approa...

Using streamlines to visualize acoustic energy flow across boundaries.

For spherical waves that radiate from a point source in a homogeneous fluid and propagate across a plane boundary into a dissimilar homogeneous fluid, the acoustic field may differ significantly from the geometric acoustic approximation if either the source or receiver is near the interface (in acoustic wavelengths) or if the stationary phase path is near the critical angle. In such cases, the ...

Using Integral Surfaces to Visualize Cfd Simulation Data Using Integral Surfaces to Visualize Cfd Simulation Data

SUMMARY Visualization of 3D, unsteady (4D) flow is very difficult due to both perceptual challenges and the large size of 4D vector field data. Here, we describe the use of integral surfaces for visualization of CFD simulation data. By " integral " surfaces we mean surfaces based on massless particles that are integrated according to the underlying flow. Traditionally, integral curves, e.g., st...

Extracting Relations from Biomedical Texts Using Syntactic Information

Annotating and measuring temporal relations in texts

This paper focuses on the automated processing of temporal information in written texts, more specifically on relations between events introduced by verbs in finite clauses. While this problem has been largely studied from a theoretical point of view, it has very rarely been applied to real texts, if ever, with quantified results. The methodology required is still to be defined, even though the...
