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
Sistem pakar diagnosa penyakit sayuran tomat dengan menggunakan metode Forward Chaining
Full text linkSayuran tomat adalah komoditas yang multiguna, tidak mengherankan jika komoditas terus berkembang di area pertanian dan perdagangan internasional.Karena itu akan sangat mengkhawatirkan jika tanaman tomat banyak yang
menderita penyakit, tetapi tidak tahu bagaimana cara menanganinya karena tidak bisa berkonsultasi langsung dengan pakar pertanian. Namun semua hal itu dapat diatasi dengan adanya sistem pakar yang dapat mendiagnosa 16 jenis penyakit yang berasal dari 34 gejala yang berbeda. Sistem pakar ini dibangun menggunakan kombinasi teknologi web populer terbaru yaitu PHP 5, HTML 5, CSS 3 , jQuery dan MySQL. Perancangan yang digunakan yaitu SSAD (Structured System Design and Analisis). Metode pengembangan perangkat lunak menggunakan metode waterfall atau yang lebih dikenal dengan sekuensial linier.Sistem pakar diagnosa penyakit sayuran tomat ini diharapkan dapat membantu petani yang
kesulitan berkonsultasi dengan pakar pertanian dengan cara memberikan solusi setelah berkonsultasi melalui sistem. Sehingga kesulitan berkonsultasi dengan penyuluh bukan lagi halangan untuk mendapatkan hasil pertanian yang lebih baik
Seleksi Fitur Enity Resolution Dalam Kasus Prostitusi Online Di Twitter
Full text linkUsaha menemukan solusi atas maraknya prostitusi online melalui Twitter salah satunya dengan menerapkan entity resolution dari identitas akun media sosial yang memiliki fitur spesifik yang menandakan prostitusi online. Entity resolution adalah proses menentukan apakah dua referensi untuk objek dunia nyata mengacu pada objek yang sama atau berbeda. Penelitian ini menerapkan entity resolution berdasarkan fitur dengan pelatihan Regularized Logistic Regression dan penentuan Active Learning pada Dedupe dan berdasarkan graph menggunakan Neo4j dan Node2Vec.
Metode penelitian yang digunakan mencakup tahapan: (1) penyiapan data, (2) ekstraksi fitur, (3) menyusun data latih dan data uji, (4) pencocokan entity resolution, dan (5) ujicoba dan analisis hasil penelitian. Data yang digunakan adalah hasil scrapping Twitter dari tagar tertentu, dengan ekstraksi fitur berbasis pada (a) informasi pengguna pada kolom bio yang terdiri dari lokasi dan teks yang diekstraksi lebih detail menjadi spesifikasi personal dan nomor kontak, dan (b) aliran data berupa konten cuitan yang berupa tagar berdasarkan 5 tagar teratas.
Penelitian ini menemukan bahwa (1) similarity maksimal bernilai 1 ketika jumlah fitur (spesifikasi personal, lokasi dan bio) lengkap, similarity minimal bernilai 0.025662627 ketika semakin banyak jumlah data latih negatif (2) fitur yang paling mempengaruhi similarity adalah nomor hp dengan rentang terendah mulai dari 0.997678459 hingga 0.999993523 (3) parameter - length of walk per source memberikan pengaruh sehingga mencapai akurasi similarity terbaik mencapai 71,4 % (prediksi 14 dan hasil 10 ) saat parameter bernilai -d:16 -q:2 -l:80
=========================================================
The effort to find a solution for online prostitution through Twitter is by applying the entity resolution of the identity of social media accounts that have specific features that indicate online prostitution. Entity resolution is the process of determining whether two references to real-world objects refer to the same or different objects. This study applies entity resolution based on features with the Regularized Logistic Regression training and determination of Active Learning on Dedupe and based on graphs using Neo4j and Node2Vec.
The research method used includes stages: (1) data preparation, (2) feature extraction, (3) compiling training data and test data, (4) matching entity resolution, and (5) testing and analysis of research results. The data used is the result of Twitter scrapping of certain tags, with feature extraction based on (a) user information in the bio column consisting of location and extracted text in more detail into personal specifications and contact numbers, and (b) data flow in the form of cuit content in the form of a hashtag based on the top 5 tags.
This study found that (1) maximum similarity is 1 when the number of features (personal, location and bio specifications) is complete, minimum similarity is 0.025662627 when the number of negative training data (2) the most influencing similarity feature is the cellphone number with the lowest starting range from 0.997678459 to 0.999993523 (3) the parameter - length of walk per source has the effect of achieving the best similarity accuracy reaching 71.4% (prediction 14 and yield 10) when the parameter is : -d 16 -q: 2 -l: 8
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
