Functions to find edges for bibliometric networks like bibliographic coupling network, co-citation network and co-authorship network. The weights of network edges can be calculated according to different methods, depending on the type of networks, the type of nodes, and what you want to analyse. These functions are optimized to be be used on large dataset. The package contains functions inspired by: Leydesdorff, Loet and Park, Han Woo (2017) <doi:10.1016/j.joi.2016.11.007>; Perianes-Rodriguez, Antonio, Ludo Waltman, and Nees Jan Van Eck (2016) <doi:10.1016/j.joi.2016.10.006>; Sen, Subir K. and Shymal K.

Generates a list, with a size defined by the user, containing the main scientific references and the frequency distribution of authors and journals in the list obtained.
    The database is a dataframe with academic production metadata made available by bibliographic collections such as Scopus, Web of Science, etc.
    The temporal evolution of scientific production on a given topic is presented and ordered lists of articles are constructed by number of citations and of authors and journals by level of productivity.

Identifies and visualizes document overlap in any number of bibliographic datasets.
    This package implements the identification of overlapping documents through the exact match of a unique 
    identifier (e.g. Digital Object Identifier - DOI) and, for records where the identifier is absent, through a score calculated 
    from a set of fields commonly found in bibliographic datasets (Title, Source, Authors and Publication Year).
    Additionally, it provides functions to visualize the results of the document matching through a Venn diagram 
    and/or UpSet plot, as well as a summary of the matching procedure.
