Introduction

Berkeley Prosopography Services (BPS) is an open-source prosopographical toolkit that generates interactive visualizations of the biological and social connections that link documented individuals, providing a dynamic and heuristic tool for researching historical communities documented in legal and administrative archives.

We are currently exploring and developing a prototype application with a single target corpus, but will soon expand to support multiple corpora. The initial corpus is a set of Hellenistic Babylonian legal texts (cuneiform tablets).

Project Vision
  • Build a generalized SNA reasoner
  • Build graphical visualization tools for families, social networks, that support what-if and similar workflows.
  • Deployment projects build additional recognizers for names, activities, etc., and rule-bases for various languages, corpora
  • Communities prepare and import corpora, and share assertions about the corpora, in a model of collaborative research.

BPS gets ready to launch a blog: berkeleypros.wordpress.com.  We'll post  updates, developments in community and services, as they happen.  We'll share our progress and the conversations that have prompted our work.

April 23, 2013

We participated in the launch of the campus d-lab with a poster, ppt and live demo.

March 22, 2013

On March 22, BPS hosted a webinar, to which individuals who had participated in previous workshops were invited.  Laurie Pearce and Davide Semenzin demonstrated the a “state of the project”: live connection and use of BPS tools, the graph viz (running on a local stack with live data), and screen shots of features to be developed.  The audio/video file is available for download. The Q&A and comments and responses that follow were sent to PM Laurie Pearce following the webinar.

Q: Is the size of corpus limited? 10,000 texts, say?

A: There is no physical limit to the size of the corpus BPS can handle. The back-end of the system scales well, and at this point we have not encountered any issues that suggest we must limit the corpus size.  However, very large corpus (such as 10K texts) will consume more computing resources and the reasoning will take longer to complete.  A graph visualization of a corpus that large with many citations of the same people would be terribly slow to generate.


Q: Is there or will there be a conventionalized or standardized say of coding prosopographical relationships within TEI or some other format? Perhaps unique IDs for a particular individual in antiquity? This would let people build prosopographical relationships into their corpus in a standard, BPS readable way, even if their corpus is too big to upload or not public. In other words, if there were a convention, people could aim for that, even if there are technical limitations at the moment.

A:  There will be standards for the coding of prosopographical relationships, but we have not yet published them.  

Part of the process of establishing the unique ID’s for individuals will be to declare the citation of that individual in a particular text as canonical and develop a pointer to all other citations of that individual.  In the case of a corpus that is entered into BPS with all the assertions made (i.e., all namesakes disambiguated), part of the pre-processing will entail adding ids to the individuals.

 

Comment: I think one way to make the matrix one step more useful is a richer filtering set of parameters (forgive my language here; I'm not sure if I'm using the right words).  I think it would be really useful to limit connections between people that involve, say, more that 1 mina of silver or that involve cultic paraphernalia or the like.  This suggestion is probably obvious, but my interests don't have me asking who is connected, but what is connecting them (beyond, say, slave to master, or son to father).  

Response: The architecture of the system is designed to handle customization of features that can be grouped by category or property.  If the corpus curator can assign that feature an attribute, BPS will be able to filter for it.  Filtering for “greater/less than” is not feasible to mark in the TEI.  However if the user wanted to assign attributes such as “big/small amount of silver” to text, that could be the basis of filters.  We’re happy to talk about dealing with specific features on which you would like to filter and about how they would be grouped in cateogries.  Compile a list and send it to us!

 

Comment: I would love to see connections and networks plotted against geography, both local and Mesopotamia-wide.    I think even a simple map with quadrants and the ability to chart connections between two particular quadrants over a span of years could yield some remarkable information.  

Response: Geographic markers is one feature for which BPS parses.  It is necessary to be able to recognize geographic meta-data as well as be able to associate that with other specific attributes.  If the user wants to map where an activity takes place, where a text was found, where a transaction takes place, the TEI must be marked for those features. There is a lot of metadata that needs to be marked, and some functionality needs to be implemented through BPS.  Again, compiling lists of geographic features and activity/role/date markers the user would like to explore will provide us with the basis for a discussion of the user’s particular needs.     

 

Comment:  Will one be able to work with professions separately (or, perhaps I'd say overlapping-ly)?  It would be interesting to me (especially in temple contexts) to work up a matrix filtered in whatever way, and then view the results not as individuals but by their clan- or professional affiliation as a sort of meta-overlayer.  

Response: Yes.  At this point, BPS has a limited number of role/profession/clan filters operating.  But these are all to be implemented, and depend primarily on providing our technical team with the data on which to filter and the means to recognize it.  You can help us by providing lists of terms on which you would like to perform such a search (ideally, send as much information as possible, e.g.:  normalized Akkadian and orthographies subsumed under that citation form).  We need to consider the taxonomy of professions and whether several professional designations could/should be rolled up into generic categories.  Another  point for consideration is whether a profession is a life-role or an activity (or both), as that will impact how the TEI gets marked.

 

Comment: This is probably a small matter but potentially interesting … there's an opportunity here for people interested in the names themselves (that is, to run tests on theophoric or grammatical elements in names, that sort of thing).   It may be worth thinking through a separate element for Namenforschung (study of names).  Jan Tavernier would have some ideas on what tools would be useful to people with those interests.  

 Response:  Although this sort of research is a legitimate and valuable component of prosopographical research, on first look, onomastic parsing and analysis appears to be beyond BPS’s scope and mission of identifying individuals, relationships, social networks and creating graph visualizations of the results.  However, since features of names (inclusion of theophoric elements, morphological and syntactic features of the source language of the name) can be important diagnostics in establishing correlations between standard name forms and hypocoristica (nicknames, shortened forms of names), there is value in exploring the incorporation of such a component into BPS.

Laurie Pearce participated in the NEH-sponsored LAWDI at the Institute for the Study of the Ancient World (NYU).  The program may be viewed here.  Notes and observations will be posted soon.

April 8-9, 2011 Workshop

BPS held another workshop on the Berkeley campus. Participants: Patrick Schmitz, Laurie Pearce, Niek Veldhuis, Jay Crisostomo, Yoram Cohen, Mike Kozuh, Cornelia Wunsch, John Nielsen; via Skype: Caroline Waerzeggers, Allon Wagner. Also in attendance from Berkeley IST Data Services: David Greenbaum, Steve Masover, Fernando Alvarez. 
April 8: Laurie presented a brief review of the history and development of BPS in a Powerpoint presentation.  Patrick then presented the current version of the BPS tools. He described the content and functionality of the Corpora and Workspace areas of the website.  Features include the ability to load corpora, identify individuals, roles and activities.  The functionality to weight assertions made in the context of documents, inter-documents and intra-documents is in place and will be active soon.  The afternoon session was "hands-on" exploration of the tools.   Participants loaded corpora and explored both the corpora and workspace features of the service. They successfully loaded, sorted names, viewed name citations, and entered into the workspace.
April 9: Schmitz, Pearce, Nielsen, Crisostomo, Wunsch, Kozuh and Waerzeggers (via Skype) assessed the relative importance of each item in a list of desiderata Schmitz compiled on the basis of participant reactions and comments during yesterday's hands-on. The ranking of their votes will allow Pearce and Schmitz to evaluate specific items for near-term development and resolution. A view of the features discussed in this context is here.

Another corpus in preparation for BPS

In August 2010, Professor Andrea Seri returned to Berkeley for training in the preparation of texts for inclusion in the Oracc consortium and in the development corpora for BPS. Professor Seri's project focuses on an archive from the city of Uruk in the Old Babylonian period (c. 1750 BCE). The focus of the archive is the institution of the bit asiri, the prison, and her preliminary work on the social networks evident in this administrative institution appears in this diagram. Professor Seri has indicated that substantially revised diagram will appear in her forthcoming monograph and that this image is to be used only on this site and exclusively for illustrative purposes.

NEH Seminar on the Networks and Network Analysis in the Humanities

Laurie Pearce was an invited speaker at the NEH-sponsored Advanced Topics in Digital Humanities Seminar "Networks and Network Analysis in the Humanities" at UCLA in August 2010. The program of the 10-day seminar can be seen here.  She presented a "success story" (Re-)constructing cuneiform communities: ancient and modern (the slides from the presentation may be seen here).  The main thread of the narrative focused on the placement of HBTIN in the collaborative environment of the cuneiform consortium Oracc and the role of HBTIN as the demonstrator corpus for BPS. Immediate feed-back came from two young scholars who expressed interest both in the prosopography tools we are developing (in particular for a study of Enlightenment Germany and its intelligentsia) and in the linkage of marked-up original texts to the prosopographical tools (for Chinese prosopography).  This confirms our conviction that BPS has much to offer a broad range of humanities research.

BPS Workshop Brings International Scholars to Berkeley

On March 25-26,2010, BPS team members Laurie Pearce and Patrick Schmitz led a workshop attended by scholars from the cuneiform community.

BPS at CDLI meeting at UCLA.

September 2009: Laurie Pearce and Stephanie Langin-Hooper attended the CDLI meeting at UCLA. One session was devoted to the development of a CDLI seal/seal-impression database. This is being developed by Christina Tsouparopolou (Berlin) and is intended to catalogue seals and seal-impressions from all periods of usage in Mesopotamia. Pearce and Langin-Hooper presented the existing HBTIN seal-impression database. The points they highlighted included: problems in transformation of legacy databases; attribution of scholars' published descriptions of seal iconography; database design and how it influences and shapes the query and data-recovery process.

Seal-impression database edits complete.

August 2009: Ronald Wallenfels, Laurie Pearce, Jay Crisostomo and Stephanie Langin-Hooper completed the editing of the seal(-impression) database created for HBTIN. In Jan. 2009, Steve Tinney transformed Wallenfels' legacy Nota Bene files used to produce Wallenfels' 1994 catalogue raisonee, "Uruk: Hellenistic Seal Impressions" (AUWE 19. Mainz: Phillip von Zabern). The iconographic data and prosopographic notices associated with the seal-impressions are central to the creation of a full data set and underscore that the "complete object" (text and image) must be included in any artifact analysis. These data strengthen the BPS tool-set and further define the potential of the prosopography tools. Pearce and Langin-Hooper will attend a September CDLI conference in order to participate in the discussion and development of the CDLI seal catalogue.

Modern Prosopography paper presented at RAI.

July 9, 2009: Stephanie Langin-Hooper and Laurie Pearce present a paper (CDL, HBTIN & BPS: The Very Model of a Major Modern Prosopography) at the Rencontre Assyriologique Internationale, Paris. The paper explains the interconnections between CDL, HBTIN and BPS and presents a mock-up of how the prosopography tool will work. Selected slides from the Powerpoint presentation are here.

BPS presents at UC Berkeley HART symposium

  • Compile summary results of needs assessment(done Read the results_)_
  • Investigate example documents (done)
  • Design generalized architecture (done)
  • Build team (done)
  • Develop core pieces, one at a time (In process)** User-centered-design for presentation, etc.

Background Research and Related Projects

  • Oracc
    The On-line Richly Annotated Cuneiform Corpus at University of Pennsylvania is a collaborative network of projects. Linked to a global registry for cuneiform documents (the CDLI catalog), tools for corpus-development (the ATF specification and related software and web-services), educational pages (the CDLI wiki) and a free hosting service to support the development of special-interest projects. We've talked quite a bit with Steve Tinney, and are leveraging other Oracc resources as well.
  • PASE
    The Prosopography of Anglo-Saxon England (PASE) is a database which aims to cover all of the recorded inhabitants of England from the late sixth to the end of the eleventh century. It is based on a systematic examination of the available written sources for the period, including chronicles, saints’ Lives, charters, libri vitae, inscriptions, and coins.
  • Prosopographia Ptolemaica
    According to this project's website, "The Prosopographia Ptolemaica started as a list of all inhabitants of Egypt between 300 and 30 B.C., from Greek, Egyptian and Latin sources, both authors and documents. It is now being extended to the Roman and Byzantine periods. The Prosopographia Ptolemaic has been integrated in the papyrological framework of http://www.trismegistos.org Trismegistos. It is also set up in close collaboration with the Heidelberger Gesamtverzeichnis and the Duke Database of Documentary Papyri."
