de um peri´odico para medir a freq¨uˆencia com que a m´edia dos artigos em um peri´odico foi citado
em um ano espec´ıfico. O fator de impacto permite avaliar a importˆancia relativa de um peri´odico,
especialmente quando o compara com outros na mesma ´area.
O cˆomputo do fator de impacto ´e realizado dividindo-se o n´umero de citac¸˜oes no ano corrente
para artigos publicados nos dois anos anteriores, pelo n´umero total de artigos publicados nos dois
anos anteriores. Por exemplo, considere o cˆomputo do fator de impacto para os peri´odicos:

O Fator de Impacto e o Sistema de Classificac¸˜ao de Peri´odicos da CAPES
Atualmente a CAPES possui uma base de dados para a classificac¸˜ao dos peri´odicos utilizados
pelos programas de p´os graduac¸˜ao para a divulgac¸˜ao da produc¸˜ao intelectual de seus docentes e
alunos. Esta base de dados, conhecida por Qualis, abrange todas as ´areas do conhecimento e,
atualmente, se divide em peri´odicos internacionais (A,B,C) e nacionais (A,B,C).
Dentro das Engenharias IV, no qual o nosso programa de p´os-graduac¸˜ao em Engenharia El´etrica
se encontra, a classificac¸˜ao dos peri´odicos internacionais em A, B ou C “parece” seguir a seguinte
m´etrica:
•
Peri´odicos internacionais A – Fator de Impacto > 0.3, e relevante para a ´area.
•
Peri´odicos internacionais B – Fator de Impacto < 0.3 e > 0.1, e relevante para a ´area..
•
Peri´odicos internacionais C – Fator de Impacto < 0.1, incluindo tamb´em os peri´odicos n˜ao
indexados por´em “conhecidos”
Para um peri´odico nacional ser considerado n´ıvel A, basta que o mesmo pertenc¸a a alguma
Sociedade Cient´ıfica.
A lista completa dos peri´odicos que comp˜oem a base do Qualis, por t´ıtulo, por ´area de avaliac¸˜ao
ou ISSN pode ser obtida no enderec¸o abaixo, no campo consulta:

anteriormente entre si equivale a misturar alhos com bugalhos. Para n˜ao dizer outra coisa.
H´a princ´ıpios b´asicos que devem ser observados quando se fazem comparac¸˜oes neste contexto. O mais b´asico deles consiste em agrupar peri´odicos em ´areas e sub-´areas. Al´em disso, ´e de se esperar que para alguma grande ´area, como a multidisciplinar, um fator de impacto “alto”, por exemplo, de 30, possa ser considerado o limite (eg, Nature tem fator de impacto de 30.979 e Science tem fator de impacto de 29.162). Por outro lado, no contexto de Engenharia El´etrica e ´areas relacionadas, acredito que as tabelas anterio-res abarcam a maior parte dos peri´odicos e estabelecem sub-tetos para (sub-)´areas dentro da Engenharia El´etrica.
Ainda exemplificando, escolhendo a sub-´area de controle/filtragem/estimac¸˜ao em um contexto um tanto “m´ıope”e pessoal, particularmente eu selecionaria, das tabelas anteriores, dentro de escalas, aqueles peri´odicos que considero importantes por focarem com relevˆancia em seus fasc´ıculos t´opicos desta sub-´area.
• Peri´odicos com fator de impacto ≥ 2 – IEEE Control Systems Magazine.
• Peri´odicos com fator de impacto < 2 e ≥ 1 – IEEE Transactions on Automatic Control; Chaos; IEEE Transactions on Fuzzy Systems; Automatica; IEEE Transactions on Signal Processing; SIAM Journal on Control and Optimization; Systems and Control Letters; Journal of Process Control; IEEE Transactions on Control Systems Technology; International Journal of Bifurcation and Chaos; IEEE Transactions on Circuits and Systems I; A International Journal of Robust and Nonlinear Control.
• Peri´odicos com fator de impacto < 1 e ≥ 0.6 – International Journal of Control; IEE Proceedings Control Theory and Applications; IEEE Transactions on Aerospace and Electronic Systems; Linear Algebra and its Applications.
• Peri´odicos com fator de impacto < 0.6 e ≥ 0.4 – Journal of Optimization Theory and Applications; Fuzzy Sets and Systems; Signal Processing; Journal of the Franklin Institute; European Journal of Control; International J. Adaptive Control and Signal Processing; Control Engineering Practice; International Journal of Systems Science; J. Dynamic Systems, Measurements and Control-Trans. of the ASME.
• Peri´odicos com fator de impacto < 0.4 e ≥ 0.1 – Kybernetika; Automation and Remote Control; Computers & Electrical Engineering; Optimal Control Applications & Methods.
• Peri´odicos com fator de impacto < 0.1 – Control Engineering.
Concluindo, particularmente o c´eu n˜ao ´e o limite na ´area que foi selecionada6, e para o JCR-2003 ´e de 2.413.
