Title: |
HYBRID APPROACH TO AUTOMATIC SUMMARIZATION OF SCIENTIFIC AND TECHNICAL TEXTS |
Author: |
AIGERIM M. BAKIYEVA, TATIANA V. BATURA |
Abstract: |
The paper is devoted to the methods of automatic summarization, which use the
representation of a text in the form of a graph. And contains an attempt at
formal description of the text transformation in terms of the predicate calculus
logic. The proposed method combines the use of a linguistic knowledge base,
graph representation of texts and machine learning. The fragments of a text,
such as words, sentences, paragraphs, are represented as graph nodes, and
relations between nodes, for example, rhetorical relations, are denoted by
edges. Automatic determination of rhetorical relations in the text allows you to
set the location of the nucleus and satellite. To compile a brief annotation, it
is necessary to transform the original text, based on the assumption that the
nucleus contains the most important part of the statement. The relations between
discursive markers in the text define a hierarchy that allows one to solve
various problems of word processing in a natural language, including the task of
automatically compiling a short abstract on a large volume of text. The
summarization process created by the authors consists of six main steps:
preprocessing, topic modeling, rhetorical analysis and transformation, weight
evaluation, sentence selection, and smoothing. Topic modeling is used to
discover key terms. First, unigram topiс models, that contain only one-word
terms, are constructed. These models are further expanded by adding multiword
terms. The most significant fragments of the source document are determined in
the process of rhetorical analysis using discursive markers. Presentation of
texts in the form of graphs helps to demonstrate the transformations with the
text necessary to highlight important fragments. In assessing the importance of
the text fragments are also included keywords, multiword and scientific terms,
describing the scientific and technical texts. To store the marker information
has created a linguistic knowledge base. The final step in the formation of the
annotation is smoothing  a text conversion procedure that allows you to make
the text of the abstract (annotation) received more coherent and consistent. The
importance of sentences is determined using discursive markers and connectors.
We used additive regularization for topic modeling (ARTM) to extract keywords
and discover the topics. Our proposed BigARTM and Rake hybrid method for
obtaining thematic models and the task of obtaining an abstract using RST
markers, action and templates showed its effectiveness and efficiency in testing
and in comparison with other methods as was shown in comparisons using the
precision, recall and F- measure calculated in a way similar to [2, 10]. |

Title: |
ARABIC DISORDERED SPEECH PHONETIC DICTIONARY GENERATOR FOR AUTOMATIC SPEECH
RECOGNITION |
Author: |
ASSAL A. M. ALQUDAH, MOHAMMAD A. M. ALSHRAIDEH, AHMAD A. S. SHARIEH |
Abstract: |
The phonetic dictionary, which is also known as pronunciation dictionary and
lexicon, contains a mapping between the words of the intended language and their
corresponding phoneme sequences. It is an essential component for developing an
Automatic Speech Recognition (ASR) system. The phonetic dictionary acts as an
intermediary component with other ASR components such as the acoustic model and
the language model. This research aims to design and develop a phonetic
dictionary generator (PDG) for Modern Standard Arabic (MSA) and Arabic
disordered speech that can be used for ASR research and development. This
rule-based PDG receives Arabic texts and transforms them into their
corresponding phoneme sequences using pre-defined rules. Since ASR systems must
accommodate different needs of speakers and users including the speech of normal
speakers and speakers with speech and articulation disorders, this PDG will be
able to produce phoneme sequences for both normal speech and disordered speech
using pre-defined rules too. The input speech from speakers with speech and
articulation disorders such as substitution and distortion articulation speech
disorders can be different from the speech of normal speakers. In this release
of the PDG, the substitution and distortion articulation speech disorders are
considered for their importance and frequent recurrence. The PDG is evaluated
using an Arabic text that contains 1,623 unique words. The output phonetic
dictionary for normal speakers contains 2,473 phoneme sequences, whereas the
output phonetic dictionary for speakers with disordered speech contains 62,997
phoneme sequences. This indicates that the output phonetic dictionary for
speakers with disordered speech is more comprehensive and contains more
possibilities and variations of the same unique word, which would ease the
recognition task in ASR systems in a manner that suits different speakers with
different pronunciation variations. |

MODERATING ROLE OF CONTENT MARKETING ON THE RELATIONSHIP BETWEEN PERCEIVED RISK
AND THE INTENTION TO ONLINE SHOPPING |
Author: |
JASSIM AHMAD AL-GASAWNEH, KHALID MOHAMMAD OMAR |
Abstract: |
This paper examined the moderation role of content marketing on the relationship
between Perceived risk and Online shopping intention in Jordan based on
perceived risk theory (PRT), Stimulus-Organism-Response theory (SOR), and
e-technology acceptance model (TAM). The questionnaire was used to obtain data
from 215 customers. Partial least squares structural equation modelling was used
to analyses the results, and this study concluded a negative relationship
between the Perceived risk and online shopping intention. Also, content
marketing was found to moderate the perceived risk in order to increase the
intent of customers toward online shopping. In practice, this study proves the
importance of adequate content marketing particularly on the product and the
online shopping procedure, as this can motivate the intention of online shopping
among customers. This study is of value to online sellers, both individuals and
companies. |

Title: |
ENTROPY-BASED FUZZY RANDOM FOREST FOR IMBALANCED DATASETS |
Author: |
SHROUK EL-AMIR, SAMIRELMOUGY |
Abstract: |
With the recent wave of data analytics accessing every domain, there is a
growing interest in handling an imbalanced classification problem. In many
datasets, the positive class size is extra smaller compared with the major class
(negative class), as in the case of disease detection, cyber-attacks, and many
data mining applications. Among the different algorithms that addressed this
problem, Random Forest (RF) attracted many researchers because of its general
robustness. But, RSs and other cost-sensitive algorithms are suffering from low
sensitivity and low precision according to positive class when dealing with
imbalanced dataset problem. In this paper, we propose and develop an
Entropy-based Fuzzy Random Forest (EFRF) algorithm to deal with imbalanced
classification problem. Fuzzy membership is applied to the training instances
such that different instances offer different contributions to the classifiers.
Samples that have a higher class certainty are assigned to larger fuzzy
memberships. EFRF uses the entropy to pay more attention to the samples with
higher class certainty to result in more robust decision making to avoid losing
information like other undersampling algorithms. The proposed algorithm showed
promising results compared to other imbalanced classification techniques
including Entropy-based Fuzzy Support Vector Machine (EFSVM) technique. It
featured both high precision and high recall which makes it an excellent choice
for security-wise application. |

LEARNING APPROACHES |
Author: |

Abstract: |
Recently, Sentiment Analysis applied to social media data has gradually become
one of the significant research interest in the data mining domain due to the
large volume of data available on social media networks. Sentiment Analysis is
concerned with analyzing text to identify opinions or emotions and categorizing
them as positive, negative or neutral. Applying sentiment analysis to short
texts such as Twitter messages is a challenging task because tweets might
contain a combination of formal and informal language, special characters,
emojis and symbols. Therefore, it is often difficult to understand the semantics
of the text and it is complex to extract the proper emotions expressed by users.
In this paper, sentiment analysis approaches, namely: lexicon-based and machine
learning approaches, are applied and evaluated on an Arabic tweets dataset
(short texts) regarding the Syrian civil war and crises. The experimental
results revealed that machine learning approaches outperformed the lexicon-based
in the context of predicting the subjectivity of tweets. In terms of machine
learning, five popular machine learning algorithms were applied and evaluated.
According to the experimental results, the Logistic Model Trees (LMT) algorithm
achieved the highest performance results, followed by the simple logistic and
the SVM algorithms, respectively. The results also showed that there are
enhancements in performance when utilizing feature selection approaches. Based
on all performance evaluation measures, the LMT algorithms reported the best
performance results (Acc= 85.55, F1= 0.92 and AUC= 0.86). |

BASED CLASSIFIER AND STACKED MACHINE LEARNING CLASSIFIERS-SVM, KNN AND C5.0 |
Author: |
SANGEETA RANI, NASIB SINGH GILL |
Abstract: |
Social Networking sites like Twitter and Facebook has offered the possibility to
users to express their opinion on various topics and events. Opinion mining is a
technique to find the sentiment of people about these topics, which can be
useful in decision support. Various government policies can also be monitored by
doing the sentiment analysis of related tweets. The objective of this research
is to enhance the accuracy of twitter sentiment classification. The paper
proposes a framework for a hybrid approach with an ensemble of stacked machine
learning algorithms and dictionary based classifier. Sentiment Score extracted
from dictionary based classifier is added as additional feature in the feature
set. Three machine learning algorithms SVM, KNN and C5.0 are stacked to build an
ensemble by using two Meta learners RF and GLM. Real time manually labeled
tweets based on “Clean India Mission†an Indian government policy is used for
implementation of the model. Proposed model is compared with different machine
learning and ensemble classifiers. Proposed hybrid model recorded higher
accuracy of 0.9066377 for 5 fold cross validation and 0.9124793 for 10 fold
cross validation as compared to 0.8667328 in case of stacked ensemble of
SVMRadial, KNN and C5.0 by using RF as Meta classifier. RF Meta classifier
performed better as compared to GLM in all stacked based ensemble. Proposed
model also recorded higher accuracy as compared to machine learning
classifiers-SVM, Naïve Bayes, Decision Tree, Random forest and Maximum Entropy.
The contribution of the research is to enhance the accuracy of stacked based
ensemble classifiers for twitter sentiment classification by using additional
sentiment score provided by dictionary based classifier. |

YASSINE DABACHINE, MOHAMED BINIZ, BELAID BOUIKHALENE, ABDESSAMAD BALOUKI |
Abstract: |
During the participation in the 2018 International Conference on Air Transport
Research, "ICRAT" the scientific community of air transport stressed the
importance of traffic control within airport taxiways. Scheduling aircraft
(ASCP) is addressed in this document for taxiways (single-track road). For
different aircraft categories, a detailed examination of the variable response
to aircraft delay is provided. A heuristic method based on the prediction of the
global conflict distribution (CDPG) is the first approach presented. In the
CDPG, two problems that restricted the implementation of the system are fixed:
the impasse situation and an optimal travel strategy. The second part details a
"first come, first served"(FCFS) planner to develop an integrated departure and
arrival management system at Mohamed V Airport. Improved traffic flow management
has been implemented to take into account directional constraints on traffic
lane links as well as crossing constraints at traffic lane intersections. Rather
than using preset itineraries, a route assignment mechanism is added. Scheduling
is applied to each route. Numerical experiments demonstrate an optimal
solution for the CDPG in a very short calculation time can be achieved. |

Abstract: |
This research presents the ILS-AntMiner rules-based algorithm, a hybrid Iterated
Local Search and Ant Colony Optimization, to improve classification accuracy and
the size of the classification model. This hybridisation aims to enhance the
classification performance in both accuracy and simplicity by increasing the
profit of neighbourhood structures in the exploitation mechanism. The
experimental results in this research are compared with the most related
ant-mining classifiers, including ACO/PSO2 and ACO/SA across various datasets.
The results indicate that the proposed classification algorithm can effectively
search the training space based on multiple structures to escape from local
optima and achieve high classification accuracy and model size. |

RECOMMENDATION ALGORITHM BASED ON TIME CONTEXT AND TAG OPTIMIZATION |
Author: |
ZHANG KAI, LI FEI DA, ZHANG XU QIAN |
Abstract: |
At present, some progress has been made in the research of context-based
recommendation algorithm and label-based recommendation algorithm. However,
there are some problems such as sparse scoring data for items by users and low
precision of recommendation results. In response to the above problems, this
paper proposes a recommendation algorithm that integrates time context and tag
optimization. The recommendation algorithm is improved by integrating user
behavior time interval and user attribute label information. Firstly, Long
Short-Term Memory (LSTM) is introduced to study the effect of time interval on
tags. Then, each output layer is combined with Latent Dirichlet Allocation (LDA)
to weigh the tags with high importance. Finally, the prediction value is
obtained by fusing the scoring information. Experiments show that the new
algorithm has effectively alleviated the problem of sparse scoring data and
improves the precision of recommendation results. |

THE IMPLICATION OF THE EUROPEAN UNION’S GENERAL DATA PROTECTION REGULATION
(GDPR) ON THE GLOBAL DATA PRIVACY |
Author: |
DR. ABDULAH M. ASERI |
Abstract: |
The study examined the implications of the European Union's General Data
Protection Regulations on Global Data Privacy. Based on a qualitative technique,
primary data were collected using semi-structured interviews. The thematic
method was used in the analysis of the interview transcripts collected from 10
interviewees. The results indicate that the new data protection is effective and
could negatively impact companies that fail to comply especially those located
outside the EU. The policy in promoting data privacy necessitates a practical
methodology in seeking data consent from participants while enforcing the
viability of information acquisition and usage through affirmative action. As
part of the user-centric initiative, GDPR has developed a sense of tailored
accountability while reducing security breaches that impact on business
potentials. The requirement for enhancing content-sensitive information by
global firms and organizations increases responsibility on organizational
compliance with GDPR data policies thereby with the realization of a
considerable improvement in data security and privacy. The finding also shows
that the GDPR is likely to address most of the privacy issues associated with
the development of digital technology in the world. The policy controls the key
privacy issues associated with the data collection and management such as the
privacy, security, integrity and access among many others. Through the GDPR, the
companies will embrace strategies to enhance the rights to be forgotten and the
access aspects, hence, addressing the privacy issues. |

ROBOT NAVIGATION SYSTEM USING LASER AND A MONOCULAR CAMERA |
Author: |
TAMER ABUKHALIL, MALEK ALKSASBEH, BASSAM ALQARALLEH, ANAS ABUKARAKI |
Abstract: |
The key contribution in this research work is introducing a technique that can
be used to avoid unknown objects to a mobile robot. Most vision-based obstacle
avoidance systems tend to have high computational complexity in order to
compensate for accuracy. The proposed method tries to overcome that using
pattern recognition of two laser pointers in the view of a single camera. This
vision combination along with the program that runs on a base station is
designed as a module that detects objects around the robot. Such obstacles are
detected by calculating the intensity of the red laser points found on each
frame being captured by the camera in real-time. Distance and angle to the
objects is measured using Lagrange interpolation formula applied separately to
each laser projection in the framed image. A map is created to show the robot’s
actual distances versus estimated ones as the robot keeps track of objects which
are in the camera’s view. The algorithm successfully manages to avoid obstacles
as shown in the experiments. The effectiveness of the proposed system is
evaluated by deploying the robot and performing a simple navigation task. The
results show that the concept algorithm along with the hardware module is able
to utilize the monocular vision with classification error of 3.63%. |

Author: |
SIRIAKSORN JAKBORVORNPHAN |
Abstract: |
The trend of exchanging information data will continuously increase due to the
rapid development of mobile communication networks. The new fifth-generation
(5G) technology is designed to support the ever increasing demand for internet
traffic volume over wide coverage ranges. This paper focuses on the studies of
empirical path loss prediction models for network planning of 5G mobile
communication systems. The relationship between path loss and other wireless
propagation parameters such as transmitter-receiver antennas separation
distance, antenna heights, operating frequency are presented to improve the
performance optimisation of wireless networks. The data provided in this paper
was analysed in MATLAB computer program to predict signal path loss; estimate
radio coverage; avoid interferences; and determine received power level. The
results based on the studied model showed that the propagation path loss
decreases in accordance with the increase in base station tower antenna height.
Okumura model is the most suitable model for short-haul applications in 5G radio
network communication. |
