What Shall We Do With the Unseen Sailor?:Estimating the Size of the Dutch East India Company Using an Unseen Species Model
Get PDFHistorians base their inquiries on the sources that are available to them. However, not all sources that are relevant to the historian’s inquiry may have survived the test of time. Consequently, the resulting data can be biased in unknown ways, possibly skewing analyses. This paper deals with the Dutch East India Company its digitized ledgers of contracts. We apply an unseen species model, a method from ecology, to estimate the actual number of unique seafarers contracted. We find that the lower bound of actual seafarers is much higher than what the remaining contracts indicate: at least, thirty-six percent of the seafarers is unknown. Moreover, we find that even in periods when few records survived, we can still credibly estimate a lower bound on the unique number of seafarers

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
