Cienciometría e Informetría
La Cienciometría investiga los aspectos cuantitativos de la ciencia; es el brazo cuantitativo de la ciencia de la ciencia, de los estudios científicos de la comunicación y de los estudios de la política de la ciencia.
La Informetría investiga aspectos cuantitativos de los procesos de las ciencias de la información y de la ciencia de la biblioteca.
Cienciometría e Informetría están limitados por su interés mutuo en la literatura científica. Su orientación estadística y matemática no imposibilita los análisis por métodos cualitativos.

"The applications of bibliometric research methods are centred towards science and technology. There is an expressed need for bibliometric indicators in science policy, and databases covering scientific literature have been available for more than 30 years now. Bibliometrics and scientometrics have almost become synonymous. Within fiction literature bibliometric studies are rare. However, already in 1966 Karl-Erik Rosengren published a book called "The Literary System", in which he introduced the co-mention approach to graphically display the frame of reference of fiction book reviewers (Rosengren 1966, 1968). In fiction book reviews he identified the most frequently mentioned authors and their co-occurrences. Then he was able to draw a map with authors as nodes and the distances between them were estimated using their co-occurrences. Essentially, this is the same visualization method that Henry Small discovered, independently of Rosengren, in the early 1970ies (Small 1973), which has been widely applied in science studies (co-citation analysis)."

"What is the typical structure of interactions at a research department? To some extent that can be inferred from bibliometric studies. Firstly, we know that most papers have several authors. This is typical for papers in the life and natural sciences, which according to some studies have three or more authors. In the near future we can expect papers with four authors to be the most frequent combination. Secondly, we usually find a skewed distribution of papers by author. These two general attributes of a set of papers means that we could expect to find an internal network centred around a few productive scientists, and if there are several research groups they would show up as separate clusters. These types of network patterns have also been shown to appear empirically. Peters & VanRaan(1991) made a study of the co-authorship network of a chemical engineering department, and found clusters of authors that where centred around leading full professors. Using sociometric techniques Allen(1979) found similar structures of the internal communication networks of research labs. Intra-departmental interactions can be observed using several methods. Allen asked about discussion partners using surveys while Latour & Woolgar(1986) and Knorr-Cetina(1999) used ethnographic techniques and interviewing. These methods demand considerable time and could hardly be replicated over a longer period of time."

"The decline of Swedish scientific impact has been noted in several articles and reports. Most of the time these observations are based on the National Science Indicators Database (NSIOD) produced by Institute for Scientific Information (ISI). Let's have a look at the figures once more. Both Sweden and Netherlands show an increasing share of world output of papers, but Netherlands is increasing its output faster than Sweden (Table 1). The citation impact is also well above the World average, but it is going down for Sweden, while it is stable for Netherlands. Sweden appears to have lost its leading role already in the late 1980-ies."

"All inventors names are registered in the US-patents along with their country name. Then we can use the USPTO-server and identify all patents with a Swedish inventor. Then if we look at the percentage of those patents co-invented with other countries, US-inventors appear in about 3 percent during the years 1986-1996 (Table 1). This is a much lower figure compared to the percentage of papers co-authored with the US, which suggests that basic research is much more internationalized than technological development. However, we can note a dramatic increase over the years, which leads us to conclude that internationalization is as evident in technology as in basic research. If we study the co-inventions by region we can conclude that North America and EU carry similar weight for Swedish inventors (Table 2). The fact is that collaboration with the US is somewhat stronger. Thus, we cannot up to 1996 find evidence of any marked effect of EU-membership as is the case in basic science."

"A series of bibliometric maps based on papers in Scientometrics. They are all based on 1062 papers published in vol 1:1978 to vol 44:1999 and the records were retrieved from SSCI using the Web of Science interface."
