New release of Natural Language Processing Tools

Amir Zeldes and Luke Gessler  have spent much of the past summer improving Coptic Scriptorium’s Natural Language Processing tools, and are now happy to announce the release of Coptic-NLP V3.0.0. You can read more about what we’ve been doing and the impact on performance in our three part blog post (part 1, part 2, part 3). Some of the new improvements include:

  • A new 3 step normalization framework, which allows us to hypothetically normalize bound groups before deciding how to segment them, then normalize each segment again
  • A smart rebinding module which can handle deciding to merge split bound groups based on context (useful for processing messy texts with line-breaks mid word, or other segmentation anomalies)
  • A re-implemented segmentation algorithm which is especially better at handling ambiguous groups in context (e.g. “nau” in “peja|f na|u” vs. “nau ero|f”) and spelling variation
  • A brand new, more accurate part of speech tagger
  • Higher accuracy across tools thanks to hyperparameter optimization
  • More robust test suite to ensure new errors don’t creep in
  • Various data/lexicon/ruleset improvements and bugfixes

You can download the latest version of the tools here:

We appreciate your feedback and comments, and hope to release more data processed with these tools very soon!

On the Road Summer 2019

Coptic Scriptorium is busy this summer conference season.

I had the privilege of teaching one of the Sunoikisis Digital Classicist summer session earlier in July.

I also presented some research on girls and girlhood using the Coptic Scriptorium Corpora and the Online Coptic Dictionary at the annual UCLA-St. Shenouda Society Coptic Studies Conference.  This year was the 20th anniversary conference, and the theme was Shenoute and the White Monastery.

This week,  the American Digital Humanities organization, the Association for Computational Humanities, held a conference in Pittsburgh.  There I talked about colonialism, Coptic manuscripts, and resisting continuing colonialist tendencies in digitizing these manuscripts.

Meanwhile we’ve also been working on digitizing and annotating more texts, which we hope to release in the fall.

Happy summer everyone!

Congratulating our colleagues!

Two pillars in the fields of Digital Humanities, cultural heritage, and the manuscripts of the Eastern Mediterranean world received honors this month, and we at Coptic Scriptorium wish to congratulate them both.

Dr.  Tito Orlandi was awarded the Busa Prize for lifetime achievement by the Alliance of Digital Humanities Organizations at the annual Digital Humanities Conference in Utrecht.  This honor is bestowed only every three years and thus is quite a distinguished award. Tito’s work in text encoding, developing stable identifiers for manuscripts, digital lexica, and digitization has been foundational for Coptic Studies.  He founded the Corpus dei Manoscritti Copti Letterari
(CMCL) project.

Dr. Columba Stewart, Director of the Hill Museum and Manuscript Library at St. John’s University, has been named the Jefferson Lecturer by the National Endowment for the Humanities for 2019.  Other luminaries who have received this honor include Toni Morrison, John Updike, and others.  Columba’s scholarship on early monasticism—especially Evagrius and Cassian—is well-known, widely respected, and oft-cited.  He is being honored by the NEH in particular for his work at HMML to collaborate with communities in the Middle East to photograph and preserve manuscripts manuscripts from both Christian and Muslim communities and traditions that are endangered for various political, cultural, and geographic reasons.

On a personal note, Tito has been a supportive colleague long before Coptic Scriptorium existed.  At my first Congress of the International Association of Coptic Studies in Leiden in 2000, Tito chaired the session in which I gave my paper.  I will never forget when my slides first went up on the screen with one of my photographs of the White Monastery Church, he warmly remarked how happy it made him to see the White Monastery.   This sounds like a small thing, but for a grad student at this international conference for the first time, it was a reassuring way to start my paper.  When we began Coptic Scriptorium, Tito shared with us his digital lexica, which allowed us to shave at least a year off of our labors. Conversations with Tito over the years have enriched our work.

Likewise, Columba has been a kind and generous colleague and mentor since we first met in 1999 at the Oxford Patristics Conference.  Columba’s research on early monasticism has inspired me for a long time, and his work at HMML and the vHMML online reading room is a model for public-facing cultural heritage preservation and collaborations between American scholars and heritage communities in the Middle East.  Columba’s work is sometimes framed as saving manuscripts from ISIS, but Columba himself talks about the American role in the loss of cultural heritage in the Middle East and is, in my opinion, open about the geopolitical and colonialist power dynamics at work. As I said more informally to some friends on social media, Columba is 100% the real deal.

Additionally, for those of us who work on Christianity in the ancient Eastern Mediterranean and the languages and manuscripts of these communities, these two awards cast a warm glow over the whole field.  Thank you Columba and Tito for your work, and thank you to the ADHO and the NEH for honoring them and by extension their areas of work.

A warm, sincere congratulations to you both!

Spring 2019 Corpora Release 2.7.0

We at Coptic Scriptorium are pleased to version 2.7.0 of our corpora.  The release includes several new documents:

  • several more sayings in the Coptic Apophthegmata Patrum (edited & annotated by Marina Ghaly)
  • additional fragments of Shenoute’s sermon Some Kinds of People Sift Dirt (edited & annotated by Christine Luckritz Marquis, editions provided by David Brakke)
  • Besa’s letter On Vigilance (edited and annotated by So Miyagawa and others)
  • several more fragments of the monastic canons of Apa Johannes (annotated by Elizabeth Platte and Caroline T. Schroeder, digital edition provided by Diliana Atanassova)

All documents have metadata for word segmentation, tagging, and parsing to indicate whether those annotations are machine annotations only (automatic), checked for accuracy by an expert in Coptic (checked), or closely reviewed for accuracy, usually as a result of manual parsing (gold).

You can search all corpora at https://corpling.uis.georgetown.edu/annis/scriptorium and download the data in 4 formats (relANNIS database files, PAULA XML files, TEI XML files, and SGML files in Tree-tagger format).

Our total annotated corpora are now at over 780,000 words; corpora that have human editors who reviewed the machine annotations amount to over 100,000 words.

Enjoy!

Corpora release 2.6

We are pleased to announce release 2.6 of our corpora! Some exciting new things:

  • Expanded Coptic Old Testament
  • More gold-standard treebanked texts
  • Updated files of Shenoute’s Abraham Our Father and Acephalous Work 22
  • New metadata fields to indicate whether documents have been machine annotated or if an editor has reviewed the machine annotations

Expanded Coptic Old Testament

Our Coptic Old Testament corpus is updated and expanded, with digital text from the our partners at the Digital Edition of the Coptic Old Testament project in Goettingen.  All annotations in this corpora are fully machine-processed (no human editing, because it’s BIG). You can read through all the text in two different visualizations online and search it in the ANNIS database:

  1. analytic: the normalized text segmented into words aligned with part of speech tags; each verse is aligned with Brenton’s English translation of the Septuagint
  2. chapter: the normalized text presented as chapters and verses; each word links to the online Coptic dictionary
  3. ANNIS search: full search of text, lemmas, parts of speech, syntactic annotations, etc. (see our ANNIS tips if you’re new to ANNIS)

Please keep in mind this corpus is fully machine-annotated, and we currently do not have the capacity to make manual changes to a corpus of this size.  If you notice systemic errors (the same thing tagged incorrectly often, for example) please let us know.  Otherwise, please be patient: as the tools improve, we will update this corpus.

We’ve also machine-aligned the text with Brenton’s English translation of the Septuagint. It’s possible there will be some misalignments.  Thanks for your understanding!

Treebanks

We’ve added more documents to our separate gold-standard treebank corpus.  (Want to learn more about treebanks?) In this corpus, the treebank/syntactic annotations have been manually corrected; the documents are part of the Universal Dependencies project for cross-language linguistics research.  New treebanked documents include selections from 1 Corinthians, the Gospel of Mark, Shenoute’s Abraham Our Father, Shenoute’s Acephalous Work 22, and the Martyrdom of Victor.  This means the self-standing treebank corpus is expanded, and any documents we’ve treebanked have updated word segmentation, part of speech tagging, etc., in their regular corpora.

Updated Shenoute Documents

Documents in the corpora for Shenoute’s Abraham Our Father and Acephalous Work 22 have several updates.

First, some documents are in our treebank corpus and are now significantly more accurate in terms of word segmentation, tagging, etc.

Second, we’ve added chapter and verse segmentation to these works.  Since there are no comprehensive print editions of these works with versification, we’ve applied our own chapter and verse numbers.  We recognize that versification is arbitrary, but nonetheless useful for citation.  For texts transcribed from manuscripts, chapter divisions typically occur when an ekthesis occurs in the manuscript. (Ekthesis describes a letter hanging in the margin.)  They do not necessarily occur with each ekthesis (if ekthesis is very frequent), but we try to make the divisions occur only with ekthesis.  Verses typically equal one sentence, sometimes more than one sentence per verse for very short sentences or more than one verse per sentence for very long Shenoutean sentences.

Third, we’ve added “Order” metadata to make it easier to read a work in order if it’s broken into multiple documents.  Check out Abraham Our Father, for example: the first document in the list is the beginning of the work.

When you’re reading through a document, click on “Next” to get the next document in reading order.  (If there are multiple manuscript witnesses to a work, we’ll send you to the next document in order with the fewest lacunae, or missing segments.)

Of course, you can always click on documents in any order you want to read however you like!

And everything is fully searchable across all documents in ANNIS.

New Metadata Fields Documenting Annotation

We sometimes get asked: which corpora do scholars annotate and which corpora are machine-annotated?  The answer is complicated — almost everything is machine annotated, with different levels of scholarly review.  So we’re adding three new metadata fields to help show users what kinds of annotation each document get:

  • Segmentation refers to word segmentation (or “tokenization”) performed by the tokenizer tool.
  • Tagging refers to part of speech, language of origin, and lemma tagging performed by our tagger
  • Parsing refers to dependency syntax annotations (which are part of our treebanking)

Each of these fields contains one of the following values:

  • automatic: fully machine annotated; no manual review or corrections to the tool output
  • checked: the tool has annotated the text, and a scholar has reviewed the annotations before publication
  • gold: the tools have been run and the annotations have received thorough review; this value usually applies only to documents that have been treebanked by a scholar (requiring rigorous review of word segmentation and tagging along the way)

For example, in the first image of document metadata visible in ANNIS, the document has automatic parsing; a scholar has checked the word segmentation and tagging.

In the next image of document metadata, a scholar has treebanked the text, making segmentation, tagging, and parsing all gold.

We are rolling out these annotations with each new corpus and newly edited corpus; not every corpus has them, yet — only the ones in this release.  Our New Testament and Old Testament corpora are machine-annotated (automatic) in all annotations.

 

We hope you enjoy!

Research Talk, Georgetown University Linguistics Speaker Series

In September, as part of the Georgetown University Department of Linguistics Friday Speaker Series, the project presented a summary of our latest work and our goals for the new NEH Digital Humanities Advancement Grant we received. “A Linked Digital Environment for Coptic Studies”.  Caroline T. Schroeder provided an overview of the project. Amir Zeldes presented the technology required to machine-process Coptic text in order to produce an annotated, digital corpus and linked online lexicon. Rebecca Krawiec discussed the research potential of an annotated digital corpus for research in early monasticism. Elizabeth Platte introduced the concept of linked data and demonstrated our linked geographic data features. (Christine Luckritz Marquis was scheduled present research on space and place in monastic literature but was unfortunately sidelined by a hurricane.)

Material of Christian Apocrypha Conference

In December, Caroline T. Schroeder gave a paper at the Material of Christian Apocrypha Conference hosted at the University of Virginia, under the auspices of the North American Society for the Study of Christian Apocryphal Literature.  Dr. Schroeder’s paper, “The Materiality of Digital Apocryphal Studies,” addressed the role of digital humanities in studying the colonial history of manuscripts, people and places in early Christian literature, and public humanities.  It was part of a panel on Christian Apocrypha and the Digital Humanities, which also included papers by James Walters (Rochester College) on “The Digital Syriac Corpus: A New Resource for the Study of Syriac Texts” and  Brandon Hawk (Rhode Island College) on “The Medieval Social Network of the Gospel of Pseudo-Matthew”.  Datasets used in the presentation are available at Dr. Schroeder’s GitHub site.
