KCIRec: Fusion of Knowledge Graph Information and Collaborative Information for Recommendation

Traditional recommender systems that are based on CF (Collaborative Filtering) usually suffer from the user-item interaction data sparsity problem. With the development of end-to-end models founded on GNNs, the sparsity issue can be addressed by introducing additional sources of information such as knowledge information. However, these models are insufficient to fuse multi-source information. To fill this gap, in this paper, we propose an end-to-end GNN based model called KCIRec , which fuses both K _ nowledge graph C _ ollaborative information and user-item I _ nteraction information for Rec _ ommender system.Technically, a type of two-channels’ information propagation and aggregation mechanism are conceived to generate the representation of user-item interactions graph and collaborative knowledge graph respectively.In addition, we design an attention mechanism to adaptively fuse the collaborative information and knowledge graph information extracted from the above two graph. Extensive experiments on three real-world datasets show improvements of our proposed KCIRec model over thestate-of-the-art methods such as KGNN-LS, KGAT, and CKE. The promising results show that the proposed KCIRec is able to effectively fuse knowledge graph information and improve recommender systems’ accuracy.
Development of emotional skills in schoolchildren with special educational needs in Primary Schooll

Education is an extremely complex and profound process. Education based on emotional intelligence starts from the fact that all the action, both important and small, ones allow the creation of a healthy balance in relationships with children. Actions must emphasize the importance of feelings and help us and our children, control our emotions, instead of actiong impulsively or being overwhelmed by feelings.
Fake News Detection via Graph-Based Markov Chains

Social media platforms have seen a major boom in the past decade. Apart from entertainment and establishing social connections, the use of social media to read news articles has become prevalent. News has not only become less costly but also fast and accessible. However, accessing news via social media has its own demerits. It is next to impossible for the end users to establish the validity of the news articles. Manual review of each and every article on the internet is neither quick nor economically feasible, considering the vast amount of news articles that are published on day-to-day basis. Hence, there arises a need for quick and highly accurate machine learning models to detect the fake news articles. In this paper, we propose a method to detect fake news via Graph based Markov chains. We initiate the classification process by first segregating the fake news articles from the real ones, then training two separate Markov Chains for both the classes, and finally calculating the probability that a news article was generated by a given Markov Chain. Our approach of establishing similarity between a text sequence and a Markov chain relies on probabilistic and statistical calculations, attained by performing random walks on the Markov chains. Such an approach has proven to provide a high accuracy on multiple datasets.
Workshop Kreatif Karakter Wayang Material Limbah Sebagai Media Pengenalan Seni Tradisi Untuk Siswa Sd Negeri VI Mojosongo Surakarta

Wayang has a lengthy history in Indonesia, with each part of the archipelago having its own distinctive development and legends. Until today, wayang has remained a typical feature of each region’s culture. The phenomena of extremely strong globalization current flow today, where in the increasingly fragile state of the nation’s morals with the emergence of hedonistic and individualistic cultures, impacted life among the younger generation. The fading awareness of moral principles passed down through centuries run by ancestors has begun to be altered by norms and rules from the west, which do not correspond to the conditions of the original society. One of the solutions to counteract or reduce the foreign culture is through cultural arts. This activity serves as the effort to preserve traditional art, especially wayang and as a medium of character education for elementary school students. The implementation of activities is at a public elementary school, SD Negeri Mojosongo VI Surakarta.

Knowledge Tracing via Attention Enhanced Encoder-Decoder

The knowledge tracing model takes students' learning behaviours data as input to determine their current knowledge status and predict their future answers. The learning behaviours data describes three main types of learning behaviours: learning process, learning end, and learning interval. The classical knowledge tracing models only use the data of the learning end, which contains limited information and the models cannot accurately describe constraint in the same learning behaviour in the time series. Subsequent models add other types of learning behaviours data but do not integrate different types of learning behaviours, and the models cannot accurately describe collaboration in different learning behaviours. To address these issues, knowledge tracing via attention-enhanced encoder-decoder is proposed to synthesize and analyse the three types of learning behaviours mentioned above and firstly adopts the multiheaded attention mechanism to describe constraint in the same learning behaviours; secondly adopts the channel attention mechanism modelling collaboration in the three types of learning behaviours. In the experiments, various comparisons are made with related models on several real data sets, and the results show that our model achieves certain advantages in terms of performance and knowledge state representation. In terms of practical application, an intelligent learning platform based on the model has been implemented, which predicts the future answer of students in the teaching process of two offline courses: computer and English and has achieved better performance than other knowledge tracing models.
Pembuatan dan Penggunaan Replika Sedimen Tsunami Purba untuk Media Pembelajaran Tsunami

The evidence of past disasters can be used to support disaster risk reduction efforts. Many records of past disasters are obtained in the field based on geological studies related to disasters, for example the paleotsunami sediments of the Gua Ek Leuntie. The education process for this evidence cannot be carried out directly in the field. Therefore, an effort is needed so that evidence of past disasters can be presented to the community, for example through making replicas. This study aims to describe the process of making a replica of the Gua Ek Leuntie tsunami sediment and evaluate its design and use as a learning tool about the tsunami. Making a replica of the tsunami sediment of the Gua Ek Lentie was carried out using modeling techniques. The replica was placed in the Tsunami Museum to be assessed for its design and use by visitors, museum staff and artists. Data were collected by using observation and semi-structured interview techniques and then analyzed by qualitative descriptive. The result obtained is a replica that is similar to the original. Analysis of the design and use shows that replica can be a learning tool about tsunami
DOES KWL STRATEGY IMPROVE STUDENTS’ READING COMPREHENSION DURING DISTANCE LEARNING?

Penaksiran Parameter Distribusi Weibull Menggunakan Algoritma Genetika dan Particle Swarm Optimization

This study aims toestimate and compare the results of the estimated parameters of the Weibull distributionusing the Genetic Algorithm (GA) and Particle Swarm Optimization (PSO). The Weibull distribution used is a two-parameter Weibull distribution and a three-parameterWeibull distribution. In the GA Algorithm, there are evolution operators such as crossover and mutation. Meanwhile, in PSO algorithm doesn’t. The evolution operators that can optimize complex problems and a very wide search space Evaluation of the two method is carried out by observing the difference in the resulting fitness values.Based on the simulation data from the estimator obtained using the R program, it is found that the two-parameter Weibull distribution parameter and a three-parameterWeibull distribution using a AG algorithm are both used in this distribution. This is supported by the small difference in the fitness value of the GA algorithm obtained compared to the PSO algorithm. The sample space also affects the difference in fitness. The large the sample space, the greater the fitness.
Ciri Morfosemantik Afiks Derivasional {ber-} dalam Konstruksi Verba Denumeralia Bahasa Indonesia (Morphosemantic Features of Derivational Affix {ber-} in Indonesian Denumeral Verb Constructions)

This qualitative descriptive study aimed to analyze the morphosemantic features of the derivational affix {ber-} embedded in Indonesian's denumeral verbs (VDnum). The data in this study is in the form of a VDnum construction with affix of {ber-}. The research data source is the corpus Leipzig Corpora Collection-Indonesian (LCCI). The data collection technique is the corpus combined with the observation technique. The data were analyzed in stages based on the Bagi Unsur Langsung (BUL) technique according to the basic theory of Derivational Morphology and Transpositional Semantics. Based on the analysis, two findings were as follows. Firstly, the affix {ber-} is a key in trans-positioning numerals into verbs. Without the affix, the VDnum in bI cannot be realized. In addition, the affix {ber-} in the VDnum tends to: (a) derive definitive cardinal numerals, (b) create the VDnum semantic type 'state', and (c) embed the semantic role 'patient' in arguments distributed in one construction. This research concludes that morphosemantically the affix {ber-} in the construction of VDnum bI is essential in transposing numerals into verbs. Penelitian deskriptif kualitatif ini dilakukan untuk memaparkan ciri dan karakteristik morfosemantik afiks {ber-} dalam konstruksi derivasional verba denumeralia (VDnum) pada bahasa Indonesia (bI). Data dalam penelitian ini berwujud konstruksi VDnum yang berpemarkah asiks {ber-}. Sumber data penelitian adalah laman korpus bI dengan nama Leipzig Corpora Collection – Indonesian (LCCI) . Teknik pengumpulan data adalah korpus yang dikombinasikan dengan teknik observasi. Data dianalisis secara bertahap berbasis pada teknik Bagi Unsur Langsung (BUL) sesuai teori dasar Morfologi Derivasional dan Semantik Transposisional. Berdasarkan analisis, ditemukan dua hasil sebagai berikut. Pertama, secara umum, afiks {ber-} merupakan unsur kunci dalam proses transposisi numeralia menjadi verba. Tanpa afiks tersebut, konstruksi VDnum dalam bI tidak dapat terwujud. Kedua, secara khusus, afiks {ber-} dalam konstruksi VDnum berkecenderungan untuk (a) menderivasikan numeralia kardinal takrif, (b) menciptakan tipe semantik VDnum ‘keadaan’, dan (c) menyematkan status peran ‘pengalam’ pada argumen yang berdistribusi dalam satu konstruksi. Simpulan dari penelitian ini adalah secara morfosemantik afiks {ber-} dalam konstruksi VDnum bI memiliki ciri-ciri yang menjadi elemen kunci terjadinya proses transposisi numeralia menjadi verba dalam bI.
