CAT: Credibility Analysis of Arabic Content on Twitter
(
Association for Computational Linguistics (ACL)
, 2017 , Conference Paper)
Data generated on Twitter has become a rich source for various data mining tasks. Those data analysis tasks that are dependent on the tweet semantics, such as sentiment analysis, emotion mining, and rumor detection among ...
A Characterization Study of Arabic Twitter Data with a Benchmarking for State-of-the-Art Opinion Mining Models
(
Association for Computational Linguistics (ACL)
, 2017 , Conference Paper)
Opinion mining in Arabic is a challenging task given the rich morphology of the language. The task becomes more challenging when it is applied to Twitter data, which contains additional sources of noise, such as the use ...
Methodical evaluation of Arabic word embeddings
(
Association for Computational Linguistics (ACL)
, 2017 , Conference Paper)
Many unsupervised learning techniques have been proposed to obtain meaningful representations of words from text. In this study, we evaluate these various techniques when used to generate Arabic word embeddings. We first ...
Comparative Evaluation of Sentiment Analysis Methods Across Arabic Dialects
(
Elsevier
, 2017 , Conference Paper)
Sentiment analysis in Arabic is challenging due to the complex morphology of the language. The task becomes more challenging when considering Twitter data that contain significant amounts of noise such as the use of Arabizi, ...
Evaluating the lending channel of monetary transmission in Qatar
(
Inderscience Enterprises Ltd.
, 2017 , Conference Paper)
This study uses OLS, fixed effect and random effect models to evaluate the lending channel of the monetary policy transmission in Qatar over the 2000-2013 period. The growth in the loans extended by the Qatari banks is ...
The moderating role of competition and paradoxical leadership on perceptions of fairness towards IoT monitoring
(
Americas Conference on Information Systems
, 2017 , Conference Paper)
Recent advances in monitoring systems used in the workspace are stirring a great deal of controversy. Several devices connected to the internet, coined as the Internet of Things (IoT), are now used to capture and analyze ...
A need for functionally graded stiffness femoral stem for reduction in stress shielding and promoting bone growth: Computational analysis
(
American Society of Mechanical Engineers (ASME)
, 2017 , Conference Paper)
Total Hip Arthroplasty (THA) is an orthopaedic procedure that is available to reduce pain and restore the functionality of hip joints. THA has been successfully implemented for the last 40 years. However, after more than ...
Analysis of CO2 Solubility and Absorption Heat into Aqueous 1-Diethylamino-2-propanol
(
Elsevier
, 2017 , Conference Paper)
In this work, the CO2 equilibrium solubility in 2 M 1-diethylamino-2-propanol (1DEA2P) solution were determined as function of temperature (in the range of 298-333K), and CO2 partial pressure (in the range of 8-101 kPa). ...
Regeneration Energy Analysis of Aqueous Tri-Solvent Blends Containing 2-Amino-2-Methyl-1-Propanol (AMP), Methyldiethanolamine (MDEA) and Diethylenetriamine (DETA) for Carbon Dioxide (CO2) Capture
(
Elsevier
, 2017 , Conference Paper)
This study investigated the contribution of absorption heat, sensible heat and heat of vaporization towards the regeneration energy (Qreg, kJ/g-CO2) of AMP-MDEA-DETA tri-solvent blends. The experiment was conducted at ...
Environmental degradation of 30 to 50 years old reinforced concrete structures in Qatari climate
(
Advanced Engineering Solutions
