Survival analysis of author keywords: An application to the library and information sciences area

Abstract

Our purpose is to adapt a statistical method for the analysis of discrete numerical series to the keywords appearing in scientific articles of a given area. As an example, we apply our methodological approach to the study of the keywords in the Library and Information Sciences (LIS) area. Our objective is to detect the new author keywords that appear in a fixed knowledge area in the period of 1 year in order to quantify the probabilities of survival for 10 years as a function of the impact of the journals where they appeared. Many of the new keywords appearing in the LIS field are ephemeral. Actually, more than half are never used again. In general, the terms most commonly used in the LIS area come from other areas. The average survival time of these keywords is approximately 3 years, being slightly higher in the case of words that were published in journals classified in the second quartile of the area. We believe that measuring the appearance and disappearance of terms will allow understanding some relevant aspects of the evolution of a discipline, providing in this way a new bibliometric approach.

Análise de palavras-chave da produção científica de pesquisadores: o autor como indexador

“…O estudo realizado também demonstra que algumas diferenças entre marcação de usuário e indexador são distinções de palavras que poderiam ser superadas, por meio de truncamento ou lematização, além de existir igualmente outros vocabulários que diferem do vocabulário profissional, os quais poderiam ser aplicados durante a prática de atribuição de palavras-chave. chave do autor, na área de Ciência da Informação,Peset et al (2020) adaptaram um método estatístico de análise de séries numéricas discretas às palavraschave que aparecem em artigos, com o objetivo de detectar as novas palavraschave de autores, no período de um ano, para quantificar as probabilidades de sobrevivência por 10 anos, em função do impacto dos periódicos onde aparecem. Os resultados obtidos demonstram que o tempo médio de sobrevivência dessas palavras-chave é de três anos, e um pouco maior, em casos de artigos publicados no segundo quartil da área; muitas novas palavras-Hagedorn e processo de navegação e que o uso do vocabulário e sua estrutura contribui e influencia o processo de indexação e, consequentemente, a recuperação.A análise do Tesauro da Corte Interamericana de Direitos Humanos, realizada por Frota (2014), teve o objetivo de apontar elementos que cooperem para o aperfeiçoamento do Tesauro da Corte.…”

Physical Activity and Exercise: Text Mining Analysis

“…After pre-processing, we analysed a total of 85,368 documents published in the WOS after removing duplicates. Figure 2 shows the exponential increase in the number of articles published since 1990 due to the large number of journals recently included in the WOS in the different categories [ 2 ]. Obviously, we cannot dismiss the importance of the field of knowledge we analysed, and it seems that the interest of the scientific community in issues concerning the inclusion of different populations through exercise and sport is also a topical subject [ 10 ].…”

“…This helps us on many occasions to know a subject in depth, but it also leads to losing a global vision of the state of the art of the topic studied. The number of publications on a specific topic has been growing exponentially since the late 1980s [ 2 ]. To date, the ways of knowing the reality and the trends of the importance of what is being studied in a work field involves consulting meta-analysis, systematic reviews or reviews of the topics [ 3 ].…”

Information Visualization from the Perspective of Big Data Analysis and Fusion

“…e information isolated island and overloading of book data hinder users from acquiring and sharing of L&I [20,21]. L&I information is commonly organized in two modes: information fusion and information aggregation [22,23].…”
