In this paper, we proposed an integrated deep learning model for factoid question answering system. This study uses the Delta Reading Comprehension Dataset (DRCD) to build a model to implement a factoid question answering system and to combine the classification of question and answer to evaluate with exact match (EM) and F1 score. The study determines whether the comparison can increase the proportion of EM and whether the expected answer type can effectively increase the answer accuracy rate. To perfect the transformation, a question-and-answer system that uses the BERT pre-training model is applied to the DRCD dataset together with the expected answer type analysis and comparison. The contribution of this paper is that we proposed a system architecture of factoid question answering (QA) system using BERT with question expected answer type (Q-EAT) and answer type classification (AT) models. Findings confirm that the classification of question and answer can improve the EM ratio. When the question sentence and the answer classification are the same, the prediction accuracy EM of the question answering system will be improved.","PeriodicalId":93159,"journal":{"name":"2020 IEEE 21st International Conference on Information Reuse and Integration for Data Science : IRI 2020 : proceedings : virtual conference, 11-13 August 2020.

Machine learning applications are not limited to autonomous cars or robotics but are widely used in almost all sectors including finance, healthcare, entertainment, government systems, telecommunications, and many others. Due to a lack of enterprise ML strategy, many enterprises still repeat the tedious steps and spend most of the time massaging the required data. It is easier to access a variety of data because of big data lakes and data democratization. Despite it and decent advances in ML, engineers still spend significant time in data cleansing and feature engineering. Most of the steps are often repeated in this exercise. As a result, it generates identical features with variations that lead to inconsistent results in testing and training ML applications. It often stretches the time to go-live and increases the number of iterations to ship a final ML application. Sharing the best practices and best features are not only time-savers but they also help to jumpstart ML application development. The democratization of ML features is a powerful way to share useful features, to reduce time go-live, and to enable rapid ML application development. It is one of the emerging trends in enterprise ML application development and this paper presents details about a way to achieve ML feature democratization.","PeriodicalId":93159,"journal":{"name":"2020 IEEE 21st International Conference on Information Reuse and Integration for Data Science : IRI 2020 : proceedings : virtual conference, 11-13 August 2020.

Multilayer Perceptron (MLP) technique is a machine learning technique used in detecting attack vs. benign data. However, it is difficult to construct any effective model when there are imbalances in the dataset that prevent proper classification of attack samples in data. In this research, we use UGR’16 dataset to conduct data wrangling initially. This technique helps to prepare a test set from the original dataset to train the neural network model effectively. We experimented with a series of inputs of varying sizes (i.e. 10000, 50000, 1 million) to observe the performance of the MLP neural network model with distribution of features over accuracy. Later, we use Generative Adversarial Network (GAN) model that produces samples of different attack labels (e.g. blacklist, anomaly spam, ssh scan) for balancing the dataset. These samples are generated based on data from the UGR’16 dataset. Further experiments with MLP neural network model shows that a balanced attack sample dataset, made possible with GAN, produces more accurate results than an imbalanced one.","PeriodicalId":93159,"journal":{"name":"2020 IEEE 21st International Conference on Information Reuse and Integration for Data Science : IRI 2020 : proceedings : virtual conference, 11-13 August 2020.

While there are tools to define AOIs to extract eye movement data for the analysis of gaze measurements, they may require users to draw boundaries of AOIs on eye tracking stimuli manually or use markers to define AOIs in the space to generate AOI-mapped gaze locations. In this paper, we introduce a novel method to dynamically filter eye movement data from AOIs for the analysis of advanced eye gaze metrics. We incorporate pre-trained object detectors for offline detection of dynamic AOIs in dynamic eye-tracking stimuli such as video streams. We present our implementation and evaluation of object detectors to find the best object detector to be integrated in a real-time eye movement analysis pipeline to filter eye movement data that falls within the polygonal boundaries of detected dynamic AOIs. Our results indicate the utility of our method by applying it to a publicly available dataset.","PeriodicalId":93159,"journal":{"name":"2020 IEEE 21st International Conference on Information Reuse and Integration for Data Science : IRI 2020 : proceedings : virtual conference, 11-13 August 2020.

The huge volume of publications can be contributed to a substantial increase in the total number of academic journals, including the increasing number of predatory or fake scientific journals, which yield high volumes of poor-quality research work. The effect of this scenario is that there is an obsolete jungle of journals to flip through in searching for high-quality and relevant references for researchers, ranging from the ones who simply look for citations to cite or latest development and knowledge in a specific scientific area of study. Querying existing web search engines and research paper archived websites is not the solution to the problem, since they are m-equipped to suggest high quality publications to meet the users’ information needs. In solving this problem, we propose an elegant research paper recommender, which is unique compared with existing ones, since besides considering the topics and contents of related publications, it also examines the authority and popularity of each publication to ensure its quality. Conducted empirical study shows that our recommender outperforms existing research paper recommenders and contributes to the design of searching relevant publications.","PeriodicalId":93159,"journal":{"name":"2020 IEEE 21st International Conference on Information Reuse and Integration for Data Science : IRI 2020 : proceedings : virtual conference, 11-13 August 2020.

Meanwhile the decomposition graph algorithm and the combination query paths algorithm are designed. The query graph with spatiotemporal features is split into multiple paths, and then every path in the query graph is used to search for the best matching path in the path sets contained in the data graph. Due to the existence of inaccurate matchings, approximate matchings are performed according to the evaluation function to find the best matching path.

To date, the Bengali language does not have any sentiment lexicon of its own; only the translated versions of English lexica are available. Therefore, in this work, we focus on developing a Bengali sentiment lexicon from a large Bengali review corpus utilizing a cross-lingual approach. To build the sentiment dictionary, we first created a Bengali corpus of around 42000 drama reviews; among them, we manually annotated around 12000 reviews. Utilizing a machine translation system, labeled and unlabeled Bengali review corpus, English sentiment lexica, pointwise mutual information (PMI), and supervised machine learning (ML) classifiers in different phases, we develop a Bengali sentiment lexicon of around 1000 sentiment words. We compare the coverage of our lexicon with the translated English lexica in two evaluation datasets. The proposed lexicon achieves 70%-74% coverage in document-level and around 65% coverage in word-level, which is approximately 30%-100% improvement over the translated lexica in word-level and 30%-50% in document-level. The results demonstrate that our developed lexicon is highly effective in recognizing sentiments in the Bengali text.","PeriodicalId":93159,"journal":{"name":"2020 IEEE 21st International Conference on Information Reuse and Integration for Data Science : IRI 2020 : proceedings : virtual conference, 11-13 August 2020.
