Network Analysis <strong>and</strong> Digital Prosopography<br />
In 2009, a new digital research project, the Berkeley Prosopography Service (BPS), 533 received<br />
fund<str<strong>on</strong>g>in</str<strong>on</strong>g>g from the Office of Digital Humanities (ODH) of the NEH to create “an open source digital<br />
toolkit that extracts prosopographic data from TEI encoded text <strong>and</strong> generates <str<strong>on</strong>g>in</str<strong>on</strong>g>teractive visual<br />
representati<strong>on</strong>s of social networks.” 534 This project is led by Niek Veldhuis, al<strong>on</strong>g with Laurie Pearce<br />
<strong>and</strong> Patrick Schmitz, <strong>and</strong> they are utiliz<str<strong>on</strong>g>in</str<strong>on</strong>g>g NLP <strong>and</strong> social network analysis (SNA) techniques to<br />
extract pers<strong>on</strong>al names <strong>and</strong> family relati<strong>on</strong>ships of people menti<strong>on</strong>ed <str<strong>on</strong>g>in</str<strong>on</strong>g> texts <strong>and</strong> to then assemble a<br />
social network of people based <strong>on</strong> described activities. 535 The <str<strong>on</strong>g>in</str<strong>on</strong>g>itial tool will be applied to a corpus 536<br />
of approximately 700 cuneiform tablets from the CDLI that record sales <strong>and</strong> lease transacti<strong>on</strong>s am<strong>on</strong>g<br />
a small group of Mesopotamians from Uruk (southern Iraq) between 331 <strong>and</strong> 346 BC. After the Uruk<br />
text corpus 537 has been c<strong>on</strong>verted <str<strong>on</strong>g>in</str<strong>on</strong>g>to TEI-XML, prosopographic data will be automatically extracted<br />
from the TEI files, SNA techniques will be used to create various networks, <strong>and</strong> users will then be able<br />
to visualize the results <str<strong>on</strong>g>in</str<strong>on</strong>g> various ways:<br />
A probabilistic eng<str<strong>on</strong>g>in</str<strong>on</strong>g>e will collate all the pers<strong>on</strong>-references <str<strong>on</strong>g>in</str<strong>on</strong>g> the corpus, al<strong>on</strong>g with some<br />
basic world knowledge, like the typical length of adult activity, <strong>and</strong> will then associate the<br />
names to <str<strong>on</strong>g>in</str<strong>on</strong>g>dividual pers<strong>on</strong>s, <strong>and</strong> f<str<strong>on</strong>g>in</str<strong>on</strong>g>ally will relate the people to <strong>on</strong>e another by the k<str<strong>on</strong>g>in</str<strong>on</strong>g>d of<br />
activities they engaged <str<strong>on</strong>g>in</str<strong>on</strong>g>. The result<str<strong>on</strong>g>in</str<strong>on</strong>g>g graph model can be used to produce a variety of<br />
reports <strong>and</strong> visualizati<strong>on</strong> tools, <str<strong>on</strong>g>in</str<strong>on</strong>g>clud<str<strong>on</strong>g>in</str<strong>on</strong>g>g simple name lists <strong>and</strong> family trees, as well as<br />
<str<strong>on</strong>g>in</str<strong>on</strong>g>teractive models. By <str<strong>on</strong>g>in</str<strong>on</strong>g>tegrat<str<strong>on</strong>g>in</str<strong>on</strong>g>g graph visualizati<strong>on</strong> tools, the project will provide <str<strong>on</strong>g>in</str<strong>on</strong>g>teractive<br />
tools that let researchers explore the network of associati<strong>on</strong>s <strong>and</strong> activities. They can focus <strong>on</strong><br />
an <str<strong>on</strong>g>in</str<strong>on</strong>g>dividual, <strong>on</strong> a given type of activity (e.g., real-estate sales), or explore other aspects of the<br />
model. This should enable the researchers to answer many complex questi<strong>on</strong>s more easily, <strong>and</strong><br />
with a visual resp<strong>on</strong>se (Schmitz 2009).<br />
The BPS will provide researchers with <str<strong>on</strong>g>in</str<strong>on</strong>g>dividual workspaces <strong>and</strong> will be the first <str<strong>on</strong>g>in</str<strong>on</strong>g>dependent tool to<br />
be <str<strong>on</strong>g>in</str<strong>on</strong>g>corporated <str<strong>on</strong>g>in</str<strong>on</strong>g>to the CDLI. Dur<str<strong>on</strong>g>in</str<strong>on</strong>g>g the <str<strong>on</strong>g>in</str<strong>on</strong>g>itial grant period, beta test<str<strong>on</strong>g>in</str<strong>on</strong>g>g will be c<strong>on</strong>ducted with other<br />
corpora to test the extent to which this tool can be scaled <strong>and</strong> generalized for use <str<strong>on</strong>g>in</str<strong>on</strong>g> other<br />
prosopographical projects. The BPS is also participat<str<strong>on</strong>g>in</str<strong>on</strong>g>g <str<strong>on</strong>g>in</str<strong>on</strong>g> Project Bamboo as <strong>on</strong>e of their<br />
dem<strong>on</strong>strators.<br />
Other work us<str<strong>on</strong>g>in</str<strong>on</strong>g>g network analysis 538 as a means of explor<str<strong>on</strong>g>in</str<strong>on</strong>g>g classical prosopography has been<br />
discussed by Graham <strong>and</strong> Ruff<str<strong>on</strong>g>in</str<strong>on</strong>g>i (2007). They noted that rapid developments <str<strong>on</strong>g>in</str<strong>on</strong>g> computer technology,<br />
particularly graph theory, provided both network analysts, <strong>and</strong> c<strong>on</strong>sequently prosopographers, with<br />
new tools for answer<str<strong>on</strong>g>in</str<strong>on</strong>g>g complex questi<strong>on</strong>s <str<strong>on</strong>g>in</str<strong>on</strong>g>volv<str<strong>on</strong>g>in</str<strong>on</strong>g>g the degrees of separati<strong>on</strong> between network<br />
members or how densely or loosely c<strong>on</strong>nected networks might be:<br />
Such questi<strong>on</strong>s hold a natural <str<strong>on</strong>g>in</str<strong>on</strong>g>terest for prosopographers, who can then beg<str<strong>on</strong>g>in</str<strong>on</strong>g> to look for<br />
certa<str<strong>on</strong>g>in</str<strong>on</strong>g> characteristics—class, office, occupati<strong>on</strong>, gender—<strong>and</strong> identify patterns of c<strong>on</strong>nectivity<br />
that they might have otherwise missed when c<strong>on</strong>fr<strong>on</strong>ted with a mass of data too large for<br />
normal synthetic approaches. And yet, network analysis has been slow to take root am<strong>on</strong>g<br />
