    This paper concerns computer applications for the management of archaeological data through GIS software, as related to the 2008 excavation campaign at “Mura Bastia”, Onigo (Treviso), Italy. The approach allows for the correlation of data previously acquired with those collected more recently using newer technologies. The shift from the traditional way of drawing archaeological records to the new digital technique began during the excavation of 2007. All of the walls and the layers were documented using a total station and a digital camera (photo-mosaic method). The elaboration of raw data was obtained using Free and Open Source Software only (GRASS, E-FOTO, GIMP, OPENJUMP, gvSIG). All of the new information levels (bi-dimensional raster and vector layers) were connected with the digitized plan of the old excavation into a GIS project that became the final product of the whole work. 3D terrestrial laser scanning surveys, integrated with classical topography and digital photogrammetric methodologies, allowed us to extract an accurate and photorealistic digital model of the Onigo castle. Moreover, a partial 3D virtual anastylosis of the tower was completed thanks to the reallocation of two missing elements in their correct position

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
