Distinguishing between Coherent and Incoherent Texts

چکیده

In this paper, I show that current discourse theories are not able to explain why different orderings of the same textual segments exhibit different properties with respect to coherence. I then propose a criterion of coherence that exploits both the strong tendency of textual units that are associated with certain rhetorical relations to obey a canonical ordering and the inclination of semantically and rhetorically related information to cluster into larger textual spans. I formalize this criterion as a constraint satisfaction problem and I show how it can yield a decision procedure that is capable of distinguishing between coherent and incoherent texts. The procedure has been implemented in Lisp. Distinguishing between Coherent and Incoherent Texts

Investigation of Coherent and Incoherent Laser Beams Propagation Through Turbulent Atmosphere

In this paper propagation of combined laser beam through atmosphere is investigated. Laser beam is combined via lens array arrangement. Turbulence is considered as an affecting factor of atmosphere and its effects on transverse coherence length (Fried parameter), peak intensity, propagation efficiency, and spot size of the laser beam is investigated. Coherent and incoherent combined beam are co...

A STUDY OF GAMMA RAY EXPOSURE BUILDUP FACTORS IN STRATIFIED SHIELDS FOR POINT ISOTROPIC SOURCES, INCLUDING THE EFFECTS OF INCOHERENT AND COHERENT SCATTERING

The effects of including incoherent (bound-electron) and coherent (Rayleigh) scattering in exposure buildup factor calculations for point isotropic gamma ray sources, penetrating a two-layer water-lead shield have been investigated in the gamma ray energy (E?) range of 40 keV to 3 MeV. Incoherent scattering decreases the values of these factors in both layers up to E? ~ 200 keV and the effect i...

On Classifying Coherent/Incoherent Romanian Short Texts

In this paper we present and discuss the results of a text coherence experiment performed on a small corpus of Romanian text from a number of alternative high school manuals. During the last 10 years, an abundance of alternative manuals for high school was produced and distributed in Romania. Due to the large amount of material and to the relative short time in which it was produced, the questi...

Estimating the Coherence of Noise in Quantum Control of a Solid-State Qubit.

To exploit a given physical system for quantum information processing, it is critical to understand the different types of noise affecting quantum control. Distinguishing coherent and incoherent errors is extremely useful as they can be reduced in different ways. Coherent errors are generally easier to reduce at the hardware level, e.g., by improving calibration, whereas some sources of incoher...

A Note on Bayesian Rationality and Correlated Equilibrium

The correlated equilibrium is based on the assumptions that all players are Bayes rational, they have a common prior, and choose their strategies independently. It is shown that the common-prior assumption precludes strategic independence. More generally, if the priors of the players are equivalent, the choice of the strategies cannot be independent. By contrast, if the priors are disjoint, str...
