We are interested in knowing how well a research group in an area of knowledge is doing relatively to a pre-selected set of reference groups, where each group is composed by academics or researchers. To assess academic productivity we propose a new metric, which we call P-score. Our metric P-score assigns weights to venues using only the publication patterns of selected reference groups. This implies that P-score does not depend on citation data and thus, that it is simpler to compute particularly in contexts in which citation data is not easily available. Also, preliminary experiments suggest that P-score preserves strong correlation with citation-based metrics.

Tal problema consiste em uma variante do roteamento de veículos clássico, em que a demanda de cada cliente deve ser atendida durante um intervalo temporal pré-estabelecido. Dado o caráter altamente combinatório do problema, que pertence à classe NP-Difícil, sua resolução por abordagens puramente exatas é, em muitos casos, computacionalmente impraticável. Este fato motiva o desenvolvimento de algoritmos heurísticos para sua resolução, que são mais rápidos, porém não garantem a obtenção da melhor solução para o problema. Neste trabalho é proposto um algoritmo heurístico híbrido, que combina os métodos Iterated Local Search, Variable Neighborhood Descent e um procedimento exato de particionamento de conjunto. Esse procedimento de programação matemática é acionado periodicamente com vistas a combinar da melhor forma as rotas geradas ao longo do algoritmo. Os resultados computacionais obtidos mostram que o al...

This ranking relies on a careful analysis of the research groups in terms of their size, number of PhDs graduated, research results and their impact, among other variables. While research results are not the only variable to consider, they are frequently given special attention because of the notoriety they confer to the researchers and the programs they are affiliated with. In here we introduce a new metric for quantifying publication output, called R-Score for reputation-based score, which can be used in support to the ranking of research groups or programs. The novelty is that the metric depends solely on the listings of the publications of the members of a group, with no dependency on citation counts. R-Score has some interesting properties: (a) it does not require access to the contents of published material, (b) it can be curated to produce highly accurate results, and (c) it can be naturally used to compare publication output of research groups (e.g., graduate programs) inside a same country, geographical area, or across the world. An experiment comparing the publication output of 25 CS graduate programs from Brazil suggests that R-Score can be quite useful for providing early insights into the publication patterns of the various research groups one wants to compare.
