Most of the AES is using machine learning (ML) to enhance student’s scores but did not consider the proper construction of the essay questions. This study aims to integrate the cognitive level of Blooms’ taxonomy (BT) in constructing essay questions and compare the scores of the student. Identifying the most appropriate ML method in classifying essay exam questions (EEQ) based on BT that will be embedded in the Essay Question Generator (EQG). Using F1-Measure, the evaluation results show that the Support Vector Machine (SVM) (85.7%) outperforms Naïve Bayes (82.6%) and K-Nearest Neighbor (77.6%). Therefore, SVM together with the NLP techniques is applied to automatically extract essay questions from the given text for the teachers to select and apply. The EQG was evaluated using the scores of 375 students who answered two sets of...

This study aims to convert the extracted decision tree rules sets from decision tree algorithm and the learning path sequence of the learning management system. This paper converts decision tree and learning management system rules into deterministic finite automaton. The decision tree rule sets are rule sets used to predict the vulnerability of not having graduation on time. The learning management system rules are the backbones of the learning management system in order to provide individualized learning scheme tailored to the preferences of the learners. The conversion of decision tree rules of student graduation and adaptive learning environment lead to easier interpretation and visualization of the methods and processes involved.

During typhoons, earthquakes and other calamities, agreement about language is vital to understand each other well to avoid high number of deaths, delay in access to basic needs and slow response time. However, some of the people involved in this domain find it hard to coordinate and respond to different emergency situations due to lack of familiarization and knowledge about the different terms or concepts. In disaster risk management, the consistency and reusability of the sharing of information is important to avoid possible risks. Due to this reason, an ontology is incorporated to aid in the disaster management process. The use of ontology enables quick retrieving and incorporating "consistent data" and information related to disaster management which plays an important for making decisions efficiently. This paper aims to implement and evaluate the accuracy of Sup...

In this study, we extracted Twitter tweets about the three major airlines in the country today, Cebu Pacific, Air Asia, and Philippine Airlines. Various models, techniques and classifiers were introduced in computing the sentiment scores of the Tweets gathered which is useful to different fields like education and businesses. This study aims to apply a new approach in implementing sentiment analysis task thru pattern matching using a regular expression and implementing lexicon-based scoring of sentiments. Its main purpose is to assign the correct polarity to get the sentiments of the Filipino travelers.

However, few studies have been performed to investigate the outcomes of employing game development, rather than video games per se, in the classroom. This posed a large gap in the existing body of literature of integrating the game industry into the education sector. Thus, this study served to address this gap, and argued that game development could serve as a pedagogical methodology much like video games for introducing related Information and Communications Technology (ICT) skills such as programming and multimedia topics, among other things. Conducted over three consecutive trimesters, this study explores game development as an educational tool in promoting the development of related ICT literacy skills among freshmen students in addition to the learning acquisition of the game development itself. More specifically, this exploratory-descriptive study so...

Furthermore, the same channel provides the easiest medium to distribute illicit images and videos without an autonomous content supervision process. In this study, an application was developed grounded from a pixel-based approach and a skin tone detection filter to identify images and videos with a large skin color count and considered as pornographic in nature. With nudity detection algorithm as the foundation of the system, all multimedia files were preprocessed, segmented, and filtered to analyze skin-colored pixels by processing in YCbCr space and then classifying it as skin or non-skin pixels. Afterwards, the percentage of skin pixels relative to the size of the frames is calculated to be part of the mean baseline for nudity and non-nudity materials. Lastly, the application classifies the files as nude or not, and then filter it. The application was evaluated by supplying a dataset of 1,239 multimedia files (Images = 986; Videos = 253) collected from the Web. On the final testing set, the application obtained a precision of 90.33% and accuracy of 80.23% using the supplied dataset.

In this paper, the researchers aimed to develop a logical guessing riddle mobile gaming application that focuses on randomization of questions in the game by selecting the index together with the same generated number and derived from combining the words wit and wisdom. It also has educational features that enhances the logical thinking of a person, and improves the cultural awareness and linguistic aspect of a person. The algorithm can determine how many questions the riddle game has and that total number of questions will be considered as the length of an array that used for Fisher Yates algorithm. Each array has its own corresponding index. The index is always starting with zero up to the last number of array. The researchers set a random values and it always greater than or equal 0 and less than the index.
