No full textOn the Feature Selection and Classification Based on Information Gain for Document Sentiment Analysis
No full textSentiment analysis in a movie review is the needs of today lifestyle. Unfortunately, enormous features make the sentiment of analysis slow and less sensitive. Finding the optimum feature selection and classification is still a challenge. In order to handle an enormous number of features and provide better sentiment classification, an information-based feature selection and classification are proposed. The proposed method reduces more than 90% unnecessary features while the proposed classification scheme achieves 96% accuracy of sentiment classification. From the experimental results, it can be concluded that the combination of proposed feature selection and classification achieves the best performance so far
New Results on the (Super) Edge-Magic Deficiency of Chain Graphs
No full textLet G be a graph of order v and size e. An edge-magic labeling of G is a bijection f:V(G)∪E(G)→{1,2,3,…,v+e} such that f(x)+f(xy)+f(y) is a constant for every edge xy∈E(G). An edge-magic labeling f of G with f(V(G))={1,2,3,…,v} is called a super edge-magic labeling. Furthermore, the edge-magic deficiency of a graph G, μ(G), is defined as the smallest nonnegative integer n such that G∪nK1 has an edge-magic labeling. Similarly, the super edge-magic deficiency of a graph G, μs(G), is either the smallest nonnegative integer n such that G∪nK1 has a super edge-magic labeling or +∞ if there exists no such integer n. In this paper, we investigate the (super) edge-magic deficiency of chain graphs. Referring to these, we propose some open problems

Continuing Disputes and Validity of Voting for the Regent and Deputy Regent of Yalimo Regency in Papua Indonesia
No full textThis study examines the disputed decisions made by the Constitutional Court of the
Republic of Indonesia on the election of the Regent and Deputy Regent of Yalimo Regency,
Papua Province, in 2020 that do not adhere to the principle of permanent and final legal force.
The Constitutional Court's decision on the dispute over the election of the elected Regent and
Deputy Regent resulted in a lengthy case due to the possibility of re-election, which still
resulted in general election disputes. The author discusses the consequences of re-election,
which has the potential for ongoing disputes at the Constitutional Court of the Republic of
Indonesia, as well as non-compliance with the principle of final punishment, which has
permanent legal force from the standpoint of fairness and justice. Findings from the study of
the proposed candidate having been sentenced by the court, as well as the validity of the vote
count results in the District that has been declared valid and not re-voted in the
Constitutional Court Decision Number 97/PHP.BUP-XIX/2021 (Study of Constitutional
Court Decision Number 145/PHP BUP-XIX/2021) are also presented. According to this
study, in the dispute over the election of Yalimo's regent and deputy regent, the judge decided
on the same case, which had permanent legal force and violated the principle of legal certainty.
