"The LNCS journal Transactions on Large-Scale Data- and Knowledge-Centered Systems focuses on data management, knowledge discovery, and knowledge processing, which are core and hot topics in computer science. Since the 1990s, the Internet has become the main driving force behind application development in all domains. An increase in the demand for resource sharing across different sites connected through networks has led to an evolution of data- and knowledge-management systems from centralized systems to decentralized systems enabling large-scale distributed applications providing high scalability. Current decentralized systems still focus on data and knowledge as their main resource. Feasibility of these systems relies basically on P2P (peer-to-peer) techniques and the support of agent systems with scaling and decentralized control. Synergy between Grids, P2P systems, and agent technologies is the key to data- and knowledge-centered systems in large-scale environments. This, the fifth issue of Transactions on Large-Scale Data- and Knowledge-Centered Systems, contains nine selected full-length papers, focusing on the topics of query processing, information extraction, management of dataspaces and contents, and mobile applications."

"PT. Indosat Tbk adalah salah satu perusahaan yang berkembang pada industri telekomunikasi. Namun, PT. Indosat Tbk memiliki permasalahan mengenai customer satisfaction yang cenderung menurun dari tahun ke tahun. Data media sosial, terutama twitter, menawarkan data mengenai opini publik yang sangat padat. Namun data twitter yang masih bersifat unstructured diperlukan proses lebih lanjut untuk dapat menemukan dimensi-dimensi beserta sentimen masyarakat terhadap dimensi tersebut. Latent Dirichlet Allocation (LDA) dengan Generative Statistical modelnya memungkinkan suatu set data pengamatan dapat dijelaskan oleh kelompok yang tidak teramati. Penelitian ini menentukan 30 kelompok kata representatif dari hasil LDA. Hasilnya terdapat 18 dimensi yang paling banyak dibicarakan mengenai Indosat pada linimasa twitter. Dimensidimensi tersebut mewakili 14 dimensi yang sudah ditemukan pada penelitian-penelitian sebelumnya mengenai kepuasan pelanggan pada layanan telekomunikasi, bahkan dengan LDA mendapatkan dimensi lebih detail dan lebih real time. Masing-masing dokumen dalam dimensi tersebut diberi label sentimennya, dan ditentukan akurasinya menggunakan supervised classification, hasilnya adalah 72% akurasi dengan model Naive Bayes Classification. Mengabaikan sentimen netral, sentimen negatif Indosat masih lebih tinggi daripada sentimen positifnya, yaitu dengan 16% sentimen negatif. Persentase negatif tersebut masih didominasi dengan dimensi berkaitan dengan layanan Indosat. Sementara dominasi sentimen positif ada pada dimensi yang berhubungan dengan ketersediaan layanan untuk pengguna.

PT. Indosat Tbk is One of the companies developing in the telecommunications industry. However, PT. Indosat Tbk is very concerned about customer satisfaction which tends to decrease from year to year. Social media media, especially Twitter, offer data about public opinion that is very crowded. However, the twitter data that is still unstructured requires a further process to be able to find the dimensions and sentiments of the community towards that dimension. Latent Dirichlet Allocation (LDA) with the Generative Statistics model allows a monitoring data set to be accessed by unobserved groups. This study determines 30 groups of words that represent the results of the LDA. There are 18 dimensions that are most talked about about Indosat on the Twitter timeline. These dimensions represent the 14 dimensions found in previous studies of customer satisfaction in telecommunications services, even with LDA getting more detailed and more real-time dimensions. Each document in this dimension is labeled sentiment, and its accuracy is determined using a supervised classification, obtained 72% accuracy with the Naive Bayes Classification model. Ignoring the negative sentiment, Indosat's negative sentiment was still higher than the positive sentiment, namely with a 16% negative sentiment. The negative percentage is still a comparison with Indosat services. While the dominance of positive sentiment is in the dimensions associated with service support for users."

ABSTRACTFood is a human right that must always be fulfilled by the society with the appropriate purchasing power and high and safe food quality. This encourages food sovereignty of a country, which independently meets the food needs of its people based on a food system that is fair to the entire community. Peraturan Pemerintah Republik Indonesia Nomor 17 Tahun 2015 requires an information system on food and nutrition and the theory of e-government 3.0 evolution. Therefore, one solution that supports these regulations and the e-government 3.0 approach is the text mining approach. This research processes data from LAPOR! and online news on food sovereignty to extract information and find patterns that will produce information on food sovereignty in Indonesia so that it can assist decision-making based on data through web-based visualization representation. The type of information analysis used is Document Classification for document filtering, Named Entity Recognition which is used to find out location entities and food commodities from textual data, and Topic Modeling to find topics from a collection of text news documents and complaints LAPOR !. The algorithm used in this study is Conditional Random Fields and Conditional Markov Models for the implementation of Named Entity Recognition. Latent Dirichlet Allocation and Non-Negative Matrix Factorization for the implementation of Topic Modeling. In addition Naïve Bayes, Support Vector Machine, and Logistic Regression are used for document classification. Whereas the selection of this model uses Conditional Random Field with an F1-score value for location entities of 83.85 and a food commodity entity of 90.98 used in online news data. In the LAPOR! Complaint data, the location entity uses Conditional Markov Model with an F1-Score value of 60.35 and food commodity entities amounting to 89.74. In classifying documents, the Support Vector Machine model with unigram features has a precision value of 92.00. In Topic Modeling, the Non-Negative Matrix Factorization model has a higher coherence value than the Latent Direchlete Allocation in three experiments with different datasets. In addition, visualization of food sovereignty is based on the processing of the data above to facilitate policy making by leaders such as the Expert Team at the Kantor Staf Presiden.

ABSTRACT<>br>In recent years, the problem of measuring the credibility of information on the social network received considerable attention, especially under emergency situations. This is the consequence of too many information, especially when everyone is free to act as a source of information.The study highlights the blurring of the dividing wall between fact and hoax in Indonesia, so it causes many cases of spread of hoaxes in the media. If left unchecked it can be bad for a person or organization that attacked the issue of hoaxes. Surveys conducted by Intelligence Media Management IMM said there is a sharp increase in 2016 from 1572 content into 7311 content spread in media. And based on the results of a survey conducted by telematics community Mastel Indonesia almost of all respondents 84.5 declared disturbed by the rise of the hoax news that could disturb social harmony and impede national development.According to the Minister of Communications and Information Rudiantara, concrete steps that can be done is to filter information faster and firmer. It required the action so that the spread of hoax in the media can be derived. The purpose of this research is to identify content in social media is a hoax or not when the content is spreading. The methodology used in this research begins with collecting tweets that indicated hoax and then performed data processing by creating a text mining model that can predict a potentially hoax content or not.The result of this research is a machine learning model using LinearSVC algorithm with 91 accuracy which can predict whether tweet potentially hoax or not, thus helping the filtering of information expected to reduce the spread of hoax in Indonesia."
