There has been increasing demand to develop effective computer-assisted language training (CAPT) systems, which can provide feedback on mispronunciations and facilitate second-language (L2) learners to improve their speaking proficiency through repea
ted practice. Due to the shortage of non-native speech for training the automatic speech recognition (ASR) module of a CAPT system, the corresponding mispronunciation detection performance is often affected by imperfect ASR. Recognizing this importance, we in this paper put forward a two-stage mispronunciation detection method. In the first stage, the speech uttered by an L2 learner is processed by an end-to-end ASR module to produce N-best phone sequence hypotheses. In the second stage, these hypotheses are fed into a pronunciation model which seeks to faithfully predict the phone sequence hypothesis that is most likely pronounced by the learner, so as to improve the performance of mispronunciation detection. Empirical experiments conducted a English benchmark dataset seem to confirm the utility of our method.
Terminological consistency is an essential requirement for industrial translation. High-quality, hand-crafted terminologies contain entries in their nominal forms. Integrating such a terminology into machine translation is not a trivial task. The MT
system must be able to disambiguate homographs on the source side and choose the correct wordform on the target side. In this work, we propose a simple but effective method for homograph disambiguation and a method of wordform selection by introducing multi-choice lexical constraints. We also propose a metric to measure the terminological consistency of the translation. Our results have a significant improvement over the current SOTA in terms of terminological consistency without any loss of the BLEU score. All the code used in this work will be published as open-source.

r creating annotation projects, conducting annotations, adjudicating disagreements, and analyzing annotation results. ActiveAnno embeds a highly configurable and interactive user interface. The tool also integrates a RESTful API that enables integration into other software systems, including an API for machine learning integration. ActiveAnno is built with extensible design and easy deployment in mind, all to enable users to perform annotation tasks with high efficiency and high-quality annotation results.
With the increase in the number of published academic papers, growing expectations have been placed on research related to supporting the writing process of scientific papers. Recently, research has been conducted on various tasks such as citation wo
rthiness (judging whether a sentence requires citation), citation recommendation, and citation-text generation. However, since each task has been studied and evaluated using data that has been independently developed, it is currently impossible to verify whether such tasks can be successfully pipelined to effective use in scientific-document writing. In this paper, we first define a series of tasks related to scientific-document writing that can be pipelined. Then, we create a dataset of academic papers that can be used for the evaluation of each task as well as a series of these tasks. Finally, using the dataset, we evaluate the tasks of citation worthiness and citation recommendation as well as both of these tasks integrated. The results of our evaluations show that the proposed approach is promising.
This study aims at recognizing the differences in some skills of emotional expression
from teachers’ and parents’ perspectives between the simple mentally retardation pupils
integrated in first stage in basic learning and those who are nonintegrate
d.
The population consisted of 20 pupils of simple mentally retardation (8-12 years)
integrated in public schools in first stage in basic learning, and 20 peer pupils in private
centers. Whereas the teachers were selected (15 male/female) in public schools and (10
male/female) in private centers. Parents (80 )are the fathers and mothers of (20) pupils in
public schools and (20) pupils in private centers.
The study used the descriptive approach by designing a questionnaire to measure the
differences in some skills of emotional expression between the simple mentally retardation
pupils who are integrated in public schools and nonintegrated pupils who are in private
centers. This questionnaire was distributed to teachers and parents. Then the data were
analyzed statistically by SPSS. The results were as follows:
- There are statistically significant differences between integrated and nonintegrated
pupils on all dimensions of the scale for the sake of integrated pupils.
- There are statistically significant differences between the means of some skills of
emotional expressions (joy, love) according to the variable of gender for the sake of
females.
- There are statistically significant differences in (anger)for the sake of males.
We present in this article a game of chance (Saint Petersburg Paradox) and
generalize it on a probability space as an example of a previsible (predictable) process,
from which we get a discrete stochastic integration (DSI). Then we define a marting
ale
and present it as a good integrator of a discrete stochastic integration ∫ , which is
called the martingale transform of by such that is a previsible process.
After that we present the most important properties of the DSI, which include that the
DSI is also a martingale , the theorem of stability for it, the definition of the covariation of
two given martingales and the proof that the DSI is centered with a specific given variance.
Finally, we define Doob-decomposition and the quadratic variation and present Itȏformula
as a certain sort of it.
The crisis in Syria since the beginning of the year 2011 had devastating
effects on Syrian economy, which based on the priorities of the war
economy and stopped the economic reform programs and long-term
development plans to move to the social market economy and integration
into the world economy.
The European integrative experience is a unique experience, both in terms of the
circumstances of its establishment, or founding member states, or integrative successes that
have been achieved in a never before achieved by any economic bloc, region
al or
international integration in modern and contemporary history.
Thus, this study focus on European integrative experience in terms of integrative
successes that have been achieved, and the most important factors which helpthe
memberstates of the European Integrative process to deepen their integration both
horizontally and vertically, and help them in facing the current challenges and strengthen
the EU's position in the international arena.
Studying and drawing the soil maps is considered by using the way of data
integrating the remote sensing and the geographical information system of new and
developed technologies in which we define what all related to soil through these studies
an
d drawing maps to it for example
a possibility of drawing the following maps:
1- Drawing a map of situation and the materials of soil surface.
2- Drawing a map of difference of soil colors sensing the soil content of organic
matter.
3- A map of lands declination and their salinity and efficiency of drainage in them.
4- Drawing a map of drainage.
In the research performing and drawing the up mentioned soil maps for south-west of
Hama region by using the new technologies which they have opened for us many horizons
in all domains related to many subjects particularly, the subject of this research .
This article reviews the structure of an integrated navigation system made up of unit inertial sensors manufactured by MEMS technology, a GPS Receiver unit, magnetic compasses manufactured by MEMS technology, and a high barometric sensor. The integra
ted system is built using an Extended Kalman Filter (EKF). This reviewing is performed with the use of a closed-loop system that has simple integration namely the Loosely Coupling Integration.
After conducting several air tests to collect real navigational data, antipersonnel navigational data has been used to do the integrated navigation system analysis with EKF environment in the software Matlab.
It has been noticed after the analysis that the complementary horizontal navigation system error does not exceed 50 m. With deliberate withholding of GPS data for different periods in order to test the performance of the integrated navigation system in case of withholding the GPS signal, we have found that the integrated navigation system achieves good accuracy, where the horizontal error does not exceed 200 m value when the withholding GPS data for 120 seconds. This can be considered as small and acceptable values compared with the horizontal error value for inertial navigation unit stim300 when operating independently of up to 8200 m.
