    Social Influences in Recommendation Systems

    Full text link
    Social networking sites such as Flickr and Facebook allow users to share content with family, friends, and interest groups. Also, tags can often assign to resources. In the previous research using few association rules FAR, we have seen that high-quality and efficient association-based tag recommendation is possible, but the set-up that we considered was very generic and did not take social information into account. The proposed method in the previous paper, FAR, in particular, exhibited a favorable trade-off between recommendation quality and runtime. Unfortunately, recommendation quality is unlikely to be optimal because the algorithms are not aware of any social information that may be available. Two proposed approaches take a more social view on tag recommendation regarding the issue: social contact variants and social groups of interest. The user data is varied and used as a source of associations. The adoption of social contact variants has two approaches. The first social variant is User-centered Knowledge, to contrast Collective Knowledge. It improves tag recommendation by grouping historic tag data according to friend relationships and interests. The second variant is dubbed 'social batched personomy' and attempts to address both quality and scalability issues by processing queries in batches instead of individually, such as done in a conventional personomy approach. For the social group of interest, 'community batched personomy' is proposed to provide better accuracy groups of recommendation systems in contrast also to Collective Knowledge. By taking social information into account can enhance the performance of recommendation systems.Comment: 6 page

    Improving Performance of Relation Extraction Algorithm via Leveled Adversarial PCNN and Database Expansion

    Full text link
    This study introduces database expansion using the Minimum Description Length (MDL) algorithm to expand the database for better relation extraction. Different from other previous relation extraction researches, our method improves system performance by expanding data. The goal of database expansion, together with a robust deep learning classifier, is to diminish wrong labels due to the incomplete or not found nature of relation instances in the relation database (e.g., Freebase). The study uses a deep learning method (Piecewise Convolutional Neural Network or PCNN) as the base classifier of our proposed approach: the leveled adversarial attention neural networks (LATTADV-ATT). In the database expansion process, the semantic entity identification is used to enlarge new instances using the most similar itemsets of the most common patterns of the data to get its pairs of entities. About the deep learning method, the use of attention of selective sentences in PCNN can reduce noisy sentences. Also, the use of adversarial perturbation training is useful to improve the robustness of system performance. The performance even further is improved using a combination of leveled strategy and database expansion. There are two issues: 1) database expansion method: rule generation by allowing step sizes on selected strong semantic of most similar itemsets with aims to find entity pair for generating instances, 2) a better classifier model for relation extraction. Experimental result has shown that the use of the database expansion is beneficial. The MDL database expansion helps improvements in all methods compared to the unexpanded method. The LATTADV-ATT performs as a good classifier with high precision P@100=0.842 (at no expansion). It is even better while implemented on the expansion data with P@100=0.891 (at expansion factor k=7).Comment: 6 page

    Highly Relevant Routing Recommendation Systems for Handling Few Data Using MDL Principle and Embedded Relevance Boosting Factors

    Get PDF
    A route recommendation system can provide better recommendation if it also takes collected user reviews into account, e.g. places that generally get positive reviews may be preferred. However, to classify sentiment, many classification algorithms existing today suffer in handling small data items such as short written reviews. In this paper we propose a model for a strongly relevant route recommendation system that is based on an MDL-based (Minimum Description Length) sentiment classification and show that such a system is capable of handling small data items (short user reviews). Another highlight of the model is the inclusion of a set of boosting factors in the relevance calculation to improve the relevance in any recommendation system that implements the model.Comment: ACM SIGIR 2018 Workshop on Learning from Limited or Noisy Data for Information Retrieval (LND4IR'18), July 12, 2018, Ann Arbor, Michigan, USA, 8 pages, 9 figure

    PERBANDINGAN ALGORITMA KRUSKAL DENGAN ALGORITMA GENETIKA DALAM PENYELESAIAN MASALAH MINIMUM SPANNING TREE (MST)

    This research aims to develop a problem solving system of Minimum Spanning Tree using Kruskal Algorithm and Genetic Algorithm. The problem of Minimum Spanning Tree is how to calculate minimum distance in a complete graph where each nodes are connected and the selected edge should not make sircuit. This application system is built using Visual Basic 6.0 programming and  MySQL database. The result of the whole process of this Minimum Spanning Tree aplication system is minimum distance which is calculated using Kruskal Algorithm and Gentic Algorithm. The displayed result are both text and visualization graph which show the minimum tree of a graph. Kruskal Algorithm generally shows better result than Genetic Algorithm with minimum distance resulted and running time as the parameters. For 5-25 nodes, Kruskal Algorithm generate minimum distance up to 50%  and running time process 50 times faster than Genetic Algorithm

    Sistem Informasi Geografis Pemetaan Faktor-faktor Yang Mempengaruhi Angka Kematian Ibu (Aki) Dan Angka Kematian Bayi (Akb) Dengan Metode K-means Clustering (Studi Kasus: Provinsi Bengkulu)

    Angka Kematian Ibu (AKI) dan Angka Kematian Bayi (AKB) merupakan salah satu indikator penting dalam menilai tingkat derajat kesehatan masyarakat di suatu negara. Berdasarkan data Dinas Kesehatan Provinsi Bengkulu tahun 2012 hingga 2015, AKI dan AKB di Provinsi Bengkulu masih diatas rata-rata nasional. K-Means Clustering merupakan salah satu metode pengelompokan non hirarki yang bertujuan mengelompokkan objek sedemikian hingga jarak-jarak tiap objek ke pusat kelompok di dalam satu kelompok adalah minimum. Penelitian ini bertujuan (1) Merancang dan membangun Sistem Informasi Geografis untuk memetakan angka kematian ibu dan bayi di setiap Kota/Kabupaten di Provinsi Bengkulu menggunakan metode K-Means Clustering, (2) Mengetahui perbedaan dan status pengelompokkan angka kematian ibu dan bayi di setiap Kota/Kabupaten di Provinsi Bengkulu. Hasil penelitian yang diperoleh yaitu (1) Penelitian ini berhasil memetakan angka kematian ibu dan bayi dalam 3 kelompok, yaitu rendah, sedang dan tinggi (2) berhasil menerapkan metode K-Means Clustering (3) Persentasi AKI berdasarkan kota/kabupaten di Provinsi Bengkulu, sebagai berikut: 15% kota/kabupaten berada di tingkat rendah, 65% berada di tingkat sedang dan 20% berada di tingkat tinggi. Sedangkan persentasi AKB-nya 32,5% kota/kabupaten berada di tingkat rendah, 60% berada di tingkat sedang dan 7,5% berada di tingkat tinggi. Secara keseluruhan dapat dikatakan bahwa tingkat AKI/AKB di Provinsi Bengkulu masih belum memuaskan, yaitu < 15% AKI dan < 32,5% AKB.
