What can or cannot be data?

After two classes of my Text Mining for History and Literature class this semester at Cornell I am starting to question the limits of the word “data.”  In class we were posed with the task to define data and decide if literature is data. Initially, the answer appeared to be an overwhelming consensus that yes, literature is data but, then things began to become more murky when the discussion began to attempt to define what data actually is. This is something I had never really considered before, whether some objects or concepts could be data or not. There were many phrases thrown around about how data must be able to be read by a computer, be read algorithmically, or that it must inherently be quantifiable.

This concept of data that was created in our class confused me at the start, I began to think about emotions and thought and whether they were quantifiable aspects of life. They are caused by electrical impulses in our brains that can be measured, but can we get to this same quantifiable entity through the study of an author’ word choice. Does this fit into a typical definition of data?

At this point I think the more prudent question to ask is “what can or cannot be data?,” rather than “what is data?” We know what already is data, but if the aim is to create new knowledge and research it would be better to ask what can become data and be analyzed. Rather than focusing on what aspects of literature, history, human nature, and life fit into the preconceived notion of “data,” might it be better to see where the farthest boundaries of data lie through experimentation and attempting to understand non-traditional datasets as data? Hopefully I will come up with an answer eventually.

Sentiment Analysis of Philo of Alexandria

Sentiment analysis is the process of identifying the emotions present in a text based on the emotive connotations of the language present. By analyzing the texts with the programming language R, I produced the following graphs representing the emotions and polarity present in the entire corpus of Philo as well as his views of “man,” “woman,” “women,” and “female.” Female_EmotionFemale_Polarityemo  Man Emotion Man Polarity Philo_Polarity Woman_Emotion Woman_Polarity Women_Emotion Women_Polarity

The Freedom of Research in the Digital Humanities

Access to information is pivotal to the creation of new knowledge. However, access to new information can be difficult for a variety of reasons.  Making information available to the public is the key to furthering research and the easiest way to disseminate information to the public is to incorporate tools and techniques developed within the Digital Humanities into the research process. These tools allows information to be distributed more quickly and in an inviting and exciting way that breeds new attention and research. The division between the traditional Humanities and the Digital humanities is rapidly shrinking and soon what we consider now to be two separate entities will become one unified discipline of Humanities.

For years research has been a coveted prize for scholars, kept locked away in fear that someone else may publish their findings first. This was a logical concern; it could make or break a career. A prime example would be the original study of the Dead Sea scrolls, where for many years scholars would only release a trickle of information regarding this tremendous discovery and the raw data was kept from the public view, thus allowing only a small group of scholars to study the scrolls, and in turn generating only a small range of views regarding the deciphering and interpretation of these texts.

In our digital age, research has the ability to spread rapidly far and wide.  This can be a risk as work might be released too early or in still developing forms. However, in a digital format work can be edited and updated as research progresses while logging this progress publicly.  Posting ideas on blogs, archaeological research on www.opencontext.org, GIS information on Pleiades, creating online collections and exhibits, databasing texts, and creating networks of research all serve to expand the collective knowledge of scholarship while establishing a documented trail of development that can be easily cited and referenced. When we allow our work to be viewed by others, input increases and output grows as a result. The Digital Humanities allows for this growth as it gives scholars access to as much information that one allows to be published and gives us the ability to further research in a new and innovative way.

Chedorlaomer’s Campaign in Genesis 14

Here is a theoretical map of the campaign led by Chedorlaomer’s coalition of kings against the pentapolis of Sodom, Gomorrah, Admah, Zeboiim, and Bela. This map was created in order to further research and understand the context of Genesis 14 for my M.A. thesis I am writing on Melchizedek. The map is based on research from several commentaries on Genesis 14 for the most likely origins of the eastern kings.

Digital Models: More than a Picture

Digital modeling has mainly been a method of visualization in the archaeological realm, however it serves other purposes.  While the method of digital modeling still remains a specialized tool in the archaeological tool kit, it can also provide means to learn many facets of history.  The process of digital archaeological modeling forces the student to break the site down to its component level, a wall is not just a wall anymore, it is a system of stones working together to act as a wall and you must model each stone.  This can teach students how different cultures throughout time built their structures, leading the students to be in the mind of the ancient people they are studying.

Through working in a component style you see what elements make up the features of the site. In the program that I use, Presagis Creator, you can even apply the properties of the materials to the model to see how material types effect the construction.  It also gives you the option to view the features in ways that are not possible in real life: you can see them in isolation and even how they look underground.  This is something only possible in virtual reality; it creates “born-digital” research that could not happen without the aid of technology.

I am experiencing this first hand as I build the digital model of Tel-Azekah.  The first area I modeled was area W1 and there was a large Persian Period layer and a Middle Bronze fortification wall.  As I built these features I became very familiar with the building styles, then I moved to area E, which contains Roman period remains.  At first the new construction styles confused me, but soon I realized how the Romans style differed. I went from the rough field stone construction of the Middle Bronze age to the even hewn stones of the Roman period.  By having to reconstruct the remains, I gained a deeper understanding of these building styles that one cannot gain from reading, viewing, and even excavating.

The process of digital modeling forces the user to think about all of the aspects that go into the archaeological site.  Through modeling all the aspects of you have to think about the site like a spatial network; how does one object interact with others and questions like this fuel the modeling process. It allows me to immerse myself in a culture, to represent what they were and tell their story to a modern world.

“From Dirt to Digital” A presentation for the University of Iowa Digital Studio for the Public Arts and Humanities

Here is a video short of a presentation I gave for the Studio’s lightning rounds at the University of Iowa. Check out the Studio at http://thestudio.uiowa.edu/wp/, it is a great resource at Iowa and they are involved in a lot of great projects. The presentation is on new approaches to digital archaeological modeling that are being used for the digital model of Tel Azekah (http://azekah.org). This is one of the main research projects that I and my advisor, Robert Cargill, are currently working on.  Watch the video and see what you can do with archaeology in virtual reality.

Khirbet et-Tannur: a new approach

Online resources for the study of the ancient world are increasingly available in recent years.  Interactive websites are creating environments conducive for learning in a supplementary way to publications.  This is accomplished though online collections, mapping, and 3D modeling.  By creating these resources for as many archaeological sites as possible, we are giving history a new life and a wider spread of influence in modern life.

The Nabatean people were lost in the sands of the desert for centuries only to recently be lost in the pages of books.  This fascinating and important culture existed in the ancient Near East, stretching from Arabia, across Jordan, and into the Negev and the Sinai.  They were skillful merchants and vital to the spice trade. They are best known for their architecture; specifically the cliff side carved building of Petra.  Another site was excavated in the 1930’s by Nelson Glueck that is essential to the study of Nabatean religion, which has long been ignored: Khirbet et-Tannur.

jebel tannur 001

Khirbet et-Tannur is a Nabatean temple located in Wadi Hasa built on the summit of the 300m high Jebel Tannur 70km north of Petra.  Construction of the temple started in the 2nd-3rd century BCE and continued through three phases till the 1st century CE. The temple was highly decorated and contained statues and reliefs of many deities, such as Zeus Hadad, Atargatis, and fish and grain goddesses.  Without any remains of settlement, Khirbet et-Tannur was most likely a sanctuary for pilgrimages.  Due to its remote area the site has remained untouched for many years.

Renewed interest in the Nabatean culture and Khirbet et-Tannur has led to the recent release of two ASOR volumes on the site. The volumes detail Glueck’s excavation and propose new conclusions while giving readers an in-depth introduction to the site and the Nabatean culture of the region.  While these volumes are impressive, I wanted to create something for a wider audience.  Arising from a class project, the website for Khirbet et-Tannur was created Andrew Deloucas (now of Leiden University) and myself. The website combines an online collection of artifacts with ArcGIS mapping and Sketchup 3D models (both of which are available for download on the site) to create a resource for understanding this important site in the ancient world.  So, take a look through the site tannur.omeka.net

Preserving Apamea from Iowa

Cultural preservation is a growing concern in the modern world of archaeology and ancient Near Eastern studies. The rise and distress in the Near East has endangered archaeological sites with many becoming victims of destruction and looting. While this has been a problem since ancient times with grave robbers emptying tombs and burials for profit, the problem has become increasingly worse in modern times.

In the past few years, many sites in Syria are actively looted and destroyed due to the civil war and conflict.  This distress has created problems for archaeologists and the sites cannot be excavated, studied, or properly protected. The Roman city of Apamea has been particularly devastated. This extraordinary site boasts one of the largest standing colonnades and theatres in the Roman world.  It also contains many mosaics, church remains, and the remains of a large agora; the site was once a large hub of commerce and culture for the Syrio-Palestine Roman world. Now Apamea has been reduced to crumbling remains and looter’s pits, far from its condition in just 2011.  Below are two pictures of the site in 2011 and 2012.

In a course I am currently enrolled in at the University of Iowa, Digital Approaches to Art History, my professor, Björn Anderson, approached our class with the problem of representing and preserving history that succumbs to destruction. As a class, we decided the answer was to reconstruct the site using 3D models including Sketchup, Google Earth, and excavation reports.  I chose to model the Roman theatre, one of the largest of the Roman Empire with a cavea diameter of 139m.  As of 2010, only 1/8th of the theatre has been excavated, but thanks to excavation reports and drawings of the excavations led by Cynthia Finlayson from 2007-2010 I was able to create the reconstruction below:

From this project people will be able to view and study the ruins of Apamea from across the world.  Through preserving sites in this way scholars can create a virtual representation of the physical remains that will survive environmental and human destruction. This method of cultural preservation allows individuals who may not be versed in archaeological jargon to understand, appreciate, and draw attention to important remains that are inaccessible to many.  Through using programs like Sketchup and Google Earth, both of which have free versions, the archaeological record can come alive on the Internet and be available to everyone for free.
