Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Media Promosi Laptop Dengan Teknologi Augmented Reality Berbasis Android
No full textPerkembangan teknologi berjalan begitu pesat di era Teknologi Informasi ini, khususnya alat elektronik yang sudah banyak penggunanya yaitu laptop. Pengguna laptop tersebut telah menyebar luas di lapisan masyarakat, mulai dari pegawai, dosen, guru, siswa/siswi SMA terutama mahasiswa. Karena banyaknya peminat laptop tersebut, penjualan produk laptop pun ada dimana-mana, baik di pasar modern, toko-toko eletronik maupun pada pameran laptop. Dalam sebuah pameran, penjual laptop mengalami kesulitan dalam mempromosikan produknya, karena keterbatasan stand pada pameran sehingga tidak membawa semua jenis laptop seperti di brosur. Sedangkan pembeli membutuhkan laptop secara nyata. Baik menyangkut dimensi dan spesifikasi laptop itu sendiri. Untuk itu dirancang sebuah aplikasi media promosi laptop menggunakan augmented reality berbasis android. Teknologi Augmented Reality ini dipilih karena dapat menampilkan objek 3D secara virtual dengan memanfaatkan marker yang berupa gambar laptop tersebut kedalam lingkungan nyata secara realtime. Metode yang digunakan dalam pembuatan marker pada Augmented Reality tersebut menggunakan FAST Courner Detection karena memanfaatkan feature pada marker sebagai metode pelacakan. Berdasarkan hasil pengujian dengan melakukan quisioner dengan delapan pertanyaan, bahwa sebanyak 80,5% responden menyatakan setuju, karena selain aplikasi mudah digunakan, aplikasi ini dapat memberikan informasi yang interaktif kepada para penggunanya
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
PEMBOBOTAN PARAMETER DENGAN PAIRWISE COMPARISON PADA CASE BASED REASONING PENYAKIT TANAMAN ANGGREK MENGGUNAKAN ALGORITMA SIMILARITAS KNN BERBOBOT
Full text linkNowadays, orchid farmers or hobbyists are starting to increase, because the diversity of the unique flowers and their rarity has attracted farmers and plant hobbyists. Lots of people want this beautiful plant, but caring for this orchid plant is not easy, it requires high accuracy, so that orchid plants do not die from disease. When orchid plants are attacked by a disease, orchid farmers and hobbyists need consultation about diseases that attack orchid plants, but experts or orchid plant extension agents are relatively difficult to find. Based on this, farmers and hobbyists need a system or application that can be accessed anytime and anywhere. An expert system is the right answer to make it easier to conduct consultations without having to visit an orchid plant expert. To provide information about how to diagnose types of diseases and how to deal with orchid plant diseases, an expert system application that can represent an expert in their field is needed to provide solutions to orchid plant disease problems using the pairwise comparison method and the KNN similarity algorithm. Pairwise comparison method on case-based reasoning of orchid plant disease produced weights with 3 categories of symptoms, namely mild symptoms with a weight of 0.09, moderate symptoms with a weight of 0.24 and severe symptoms with a weight of 0.67. Weighting parameters with pairwise comparison on case-based reasoning of orchid plant disease using the weighted KNN similarity algorithm will recommend several diseases with similarity above 0.5 and diseases with similarity below 0.5 will be entered into the revise table to find a solution
