في هذا البحث ، تم اقتراح طريقة جديدة منخفضة التكلفة للتعرف على لوحات ترخيص المركبات (LPR) والتي يمكن استخدامها بسهولة في لوحات أخرى. تم استخدام تقنية تجزئة LP جديدة مع ثلاث مجموعات من نواقل الميزات مع مطابقة القالب لتشكيل الوحدتين الرئيسيتين: وحدة توطين لوحة الترخيص ووحدة LPR. تم اختبار هذه الطريقة على أكثر من 238 صورة مركبة مأخوذة من مشاهد مختلفة بخطوط وخلفيات مختلفة من دولتين عربيتين. كانت دقة التجزئة للنظام المنفذ 97.5٪ مع دقة التعرف على 99٪ للصور المشوهة إلى حد ما. يوضح النموذج المقدم أنه على الرغم من التأثير السلبي للظلال والشقوق والأوساخ وفصل الشخصيات ، أظهر النظام معدل نجاح إجمالي بنسبة 92٪ في توطين الألواح و 95٪ لتجزئة اللوحات و 92٪ للتعرف على البلد والمدينة و 99 ٪ لتجزئة الرقم والتمييز. أدى الجمع بين جميع المعدلات إلى دقة نظام كلية بلغت 93٪. مقارنة بالعديد من أنظمة LPR المتطورة ، يستخدم هذا النظام المطور حديثًا 3 مجموعات تدريب صغيرة تقلل من أوقات تشغيل الحل المقترح إلى أقل من 5 ثوانٍ باستخدام MATLAB R2008A الذي يعمل على Compaq 8510W مع ذاكرة وصول عشوائي (RAM) 4 جيجا. النتائج قابلة للمقارنة ، وفي بعض الحالات تكون أفضل مع ظروف مقيدة مثل مكان الانحراف وحجم اللوحة والإضاءة والخلفية.

Sentiment classification and sarcasm detection attract a lot of attention by the NLP research community. However, solving these two problems in Arabic and on the basis of social network data (i.e., Twitter) is still of lower interest. In this paper w
e present designated solutions for sentiment classification and sarcasm detection tasks that were introduced as part of a shared task by Abu Farha et al. (2021). We adjust the existing state-of-the-art transformer pretrained models for our needs. In addition, we use a variety of machine-learning techniques such as down-sampling, augmentation, bagging, and usage of meta-features to improve the models performance. We achieve an F1-score of 0.75 over the sentiment classification problem where the F1-score is calculated over the positive and negative classes (the neutral class is not taken into account). We achieve an F1-score of 0.66 over the sarcasm detection problem where the F1-score is calculated over the sarcastic class only. In both cases, the above reported results are evaluated over the ArSarcasm-v2--an extended dataset of the ArSarcasm (Farha and Magdy, 2020) that was introduced as part of the shared task. This reflects an improvement to the state-of-the-art results in both tasks.
This paper presents one of the top five winning solutions for the Shared Task on Sarcasm and Sentiment Detection in Arabic (Subtask-1 Sarcasm Detection). The goal of the task is to identify whether a tweet is sarcastic or not. Our solution has been d
eveloped using ensemble technique with AraBERT pre-trained model. We describe the architecture of the submitted solution in the shared task. We also provide the experiments and the hyperparameter tuning that lead to this result. Besides, we discuss and analyze the results by comparing all the models that we trained or tested to achieve a better score in a table design. Our model is ranked fifth out of 27 teams with an F1 score of 0.5985. It is worth mentioning that our model achieved the highest accuracy score of 0.7830
The ability of learning disentangled representations represents a major step for interpretable NLP systems as it allows latent linguistic features to be controlled. Most approaches to disentanglement rely on continuous variables, both for images and
text. We argue that despite being suitable for image datasets, continuous variables may not be ideal to model features of textual data, due to the fact that most generative factors in text are discrete. We propose a Variational Autoencoder based method which models language features as discrete variables and encourages independence between variables for learning disentangled representations. The proposed model outperforms continuous and discrete baselines on several qualitative and quantitative benchmarks for disentanglement as well as on a text style transfer downstream application.
Sarcasm detection is one of the top challenging tasks in text classification, particularly for informal Arabic with high syntactic and semantic ambiguity. We propose two systems that harness knowledge from multiple tasks to improve the performance of
the classifier. This paper presents the systems used in our participation to the two sub-tasks of the Sixth Arabic Natural Language Processing Workshop (WANLP); Sarcasm Detection and Sentiment Analysis. Our methodology is driven by the hypothesis that tweets with negative sentiment and tweets with sarcasm content are more likely to have offensive content, thus, fine-tuning the classification model using large corpus of offensive language, supports the learning process of the model to effectively detect sentiment and sarcasm contents. Results demonstrate the effectiveness of our approach for sarcasm detection task over sentiment analysis task.
Exploring aspects of sentential meaning that are implicit or underspecified in context is important for sentence understanding. In this paper, we propose a novel architecture based on mentions for revision requirements detection. The goal is to impro
ve understandability, addressing some types of revisions, especially for the Replaced Pronoun type. We show that our mention-based system can predict replaced pronouns well on the mention-level. However, our combined sentence-level system does not improve on the sentence-level BERT baseline. We also present additional contrastive systems, and show results for each type of edit.
