A Corpus-based Study of Temporal Signals
نویسندگان
چکیده
Automatic temporal ordering of events described in discourse has been of great interest in recent years. Event orderings are conveyed in text via various linguistic mechanisms including the use of expressions such as “before”, “after” or “during” that explicitly assert a temporal relation – temporal signals. In this paper, we investigate the role of temporal signals in temporal relation extraction and provide a quantitative analysis of these expressions in the TimeBank annotated corpus.

This paper involves in prediction of temporal relation between tensed-verb events on the basis of conjunctions in texts. For this purpose, tensed verb event data were extracted from Contemporary Persian Corpus and were examined carefully. The temporal relations between events were identified. After analyzing data on the basis of temporal relation according to Bird’s and Allen’s categorization, ...
متن کاملProper integration time of polarization signals of internetwork regions using Sunrise/IMaX data
Distribution of magnetic fields in the quiet-Sun internetwork areas has been affected by weak polarization (in particular Stokes Q and U) signals. To improve the signal-to-noise ratio (SNR) of the weak polarization signals, several approaches, including temporal integrations, have been proposed in the literature. In this study, we aim to investigate a proper temporal-integration time with which...

Consideration of comparative research as a "separate and different research process" is an issue that has not been addressed thoroughly, at least in Iran, and few of the research conducted under the title of "comparative" refer to studies conducted using different methods than the usual research methods. On the other hand, there has been a rise in the importance of interaction between different...
متن کاملDepth of anesthesia estimation based on EEG signal using brain effective connectivity between frontal and temporal regions
Background: Ensuring adequate depth of anesthesia during surgery is essential for anesthesiologists to prevent the occurrence of unwanted alertness during surgery or failure to return to consciousness. Since the purpose of using anesthetics is to affect the central nervous system, brain signal processing such as electroencephalography (EEG) can be used to predict different levels of anesthesia....
متن کاملEMG-based wrist gesture recognition using a convolutional neural network
Background: Deep learning has revolutionized artificial intelligence and has transformed many fields. It allows processing high-dimensional data (such as signals or images) without the need for feature engineering. The aim of this research is to develop a deep learning-based system to decode motor intent from electromyogram (EMG) signals. Methods: A myoelectric system based on convolutional ne...
