Server updates – part of site down tonight

We are making some updates to the document application at data.copticscriptorium.org tonight (13 December 2016) approximately 7:30-8:30 pm Pacific time/10:30-11:30 Eastern time.  The service may be down.

You can still query and access our corpora in the ANNIS database at https://corpling.uis.georgetown.edu/annis/scriptorium .  That service will not be affected.  Thanks!

Online lexicon linked to our corpora!

We have a great announcement today.  Along with our German research partners as part of the KELLIA project, we are releasing an online Coptic lexicon linked to our corpora.

For over three years, the Berlin-Brandenberg Academy of Sciences has been working on a digital lexicon for Coptic.  Frank Feder began the work.  Frank Feder began creating it, encoding definitions for Coptic lemmas in three languages: English, French, and German. The final entries were completed by Maxim Kupreyev at the academy and Julien Delhez in Göttingen.  The base lexicon file is encoded in TEI-XML.  This summer Amir Zeldes and his student, Emma Manning, created a web interface.  We will release the source code soon as part of the KELLIA project.

It may still need some refinements and updates, but we think it is a useful achievement that will help anyone interested in Coptic.

Entries have definitions in French, German, and English.

You can use the lexicon as a standalone website.  For the pilot launch, it’s on the Georgetown server, but make no mistake, this is major research outcome for the BBAW.

We’ve also linked the dictionary to our texts in Coptic SCRIPTORIUM.  You can click on the ANNIS icon in the dictionary entry to search all corpora in Coptic SCRIPTORIUM for that word.

lexicon-to-ANNIS The link also goes in the other direction.  In the normalized visualization of our texts, you can click on a word and get taken to the entry for that word’s lemma in the dictionary.  You can do this in the normalized visualization in our web application for reading and accessing texts (pictured below), or in the normalized visualization embedded in the ANNIS tool.

Of course there will be refinements and developments to come.  We would love to hear your feedback on what works, what could work better, and where you find glitches.

On a more personal note, when Amir and I first came up with the idea for the project, we dreamed of creating a Perseus Digital Library for Coptic.  This dictionary is a huge step forward.  And honestly, I myself had almost nothing to do with this piece of the project.  It’s an example of the importance and power of collaboration.

Coptic Treebank Released

Yesterday we published the first public version of the Coptic Universal Dependency Treebank. This resource is the first syntactically annotated corpus of Coptic, containing complete analyses of each sentence in over 4,300 words of Coptic excerpts from Shenoute, the New Testament and the Apophthegmata Patrum.

To get an idea of the kind of analysis that Treebank data gives use, compare the following examples of an English and a Coptic dependency syntax tree. In the English tree below, the subject and object of the verb ‘depend’ on the verb for their grammatical function – the nominal subject (nsubj) is “I”, and the direct object (dobj) is “cat”.

cat_mat

We can quickly find out what’s going on in a sentence or ‘who did what to whom’ by looking at the arrows emanating from each word. The same holds for this Coptic example, which uses the same Universal Dependencies annotation schema, allowing us to compare English and Coptic syntax.

Treebanks are an essential component for linguistic research, but they also enable a variety of Natural Language Processing technologies to be used on a language. Beyond automatically parsing text to make some more analyzed data, we can use syntax trees for information extraction and entity recognition. For example, the first tree below shows us that “the Presbyter of Scetis” is a coherent entity (a subgraph, headed by a noun); the incorrect analysis following it would suggest Scetis is not part of the same unit as the Presbyter, meaning we could be dealing with a different person.

One time, the Presbyter of Scetis went...

One time, the Presbyter of Scetis went…

One time, the Presbyter went from Scetis... (incorrect!)

One time, the Presbyter went from Scetis… (incorrect!)

To find out more about this resource, check out the new Coptic Treebank webpage. And to read where the Presbyter of Scetis went, go to this URN: urn:cts:copticLit:ap.19.monbeg.

ANNIS embeds for websites and blogs

Starting this week, there’s a new feature in our ANNIS web interface: ANNIS embeds.

The ANNIS interface can now give you an HTML snippet that you can embed on your webpage, blog post and more.

Here’s an example of an embedded visualizer for a passage from Besa’s letter to Aphthonia, in which he recounts Aphthonia’s threat to go to another monastery:

(MONB.BA 47, urn:cts:copticLit:besa.aphthonia.monbba)

The code snippet for this visualization is as follows:

<iframe src="https://corpling.uis.georgetown.edu/annis/?id=31e2a273-426f-4aaf-922a-7fa0f0b311e1" width="100%" height="500"/>

To get an embeddable snippet, click the share icon at the top left of your search result and choose the visualization you want. To share the entire set of results, use the share button at the top right of the results page. Additionally, if you want to share an ANNIS search result via e-mail, you can still copy and paste the URL as before, but now you can also get a specific shareable link for individual hits using the same share button .

Let us know if you have any feedback!

Annotation tools now include DDGLC Greek Loanword List

We are pleased to announce the release of our newest versions of some of our natural language processing tools for Coptic which incorporate the lemma list of loanwords developed by the Database and Dictionary of Greek Loanwords in Coptic (DDGLC).

The DDGLC is part of the KELLIA partnership between American and German digital Coptic projects funded by the NEH Office of Digital Humanities and the DFG.  The DDGLC, under the direction of Prof. Dr. Tonio Sebastian Richter, has been building a database of Greek loanwords in Coptic in order to facilitate the study of language contact, language borrowing, and multilingualism in Egypt.

We have integrated the Greek lemma list into our language of origin tagger, tokenizer and morphology analysis, and lemmatizer.

Our online natural language processing web service (which bundles together all of our NLP tools into one web application) also includes this new data from the DDGLC.

The Greek loanword list should greatly increase the accuracy of many of our tools.  If you use them, please let us know how it goes!

We at Coptic SCRIPTORIUM are grateful for this partnership and the generosity of the DDGLC team.

New Coptic morphological anlaysis

A new component has been added to the Coptic NLP pipe-line at:

https://corpling.uis.georgetown.edu/coptic-nlp/

This adds morphological analysis of complex word forms, including multiple affixes (e.g. derived nouns with affixes such as Coptic ‘mnt’, equivalent to English ‘-ness’), compounds (noun-noun combinations) and complex verbs. Using the automatic morphological analysis will substantially reduce the amount of manual work involved in putting new texts online, meaning we will be able to concentrate on getting more texts out there faster, as well as developing new tools and ways of interacting with the data.

Coptic NLP pipeline Part 2

With the creation of the Coptic NLP (Natural Language Processor) pipeline by Amir Zeldes, it is now possible to run all our NLP tools simultaneously without the need to individually download and run them. The web application will tokenize bound groups into words, and will normalize the spelling of words and diacritics. It will also tag for part-of-speech, lemmatize, and tag for language of origin for borrowed (foreign) words. The interface is XML tolerant (preserves tags in the input) and the output is tagged in SGML. One of the options is to encode the lines breaks in a word or sentence which is useful for encoding manuscripts. However, keep in mind to double check results because the interface is still in the beta stage.

As an example, the screenshot below is a snippet from I See Your Eagerness from manuscript MONB.GL29.

 

1.1

Notice it contains an XML tag to encode a letter as “large ekthetic”. “Large ekthetic” corresponds to the alpha letter to designate it as a large character in the left margin of the manuscript’s column of text.  This tag will be preserved in the output.

2

The results are shown above. Bounds group are shown and along with the part of speech tag abbreviated as “pos”. The snippet from I See Your Eagerness has also been lemmatized, shown as “lemma”. Also, near the bottom of the screenshot, the language of origin of borrowed (foreign) words in the snippet has been identified as “Greek”.  These tags also correspond to the annotation layers you see in our multi-layer search and visualization tool ANNIS.

We hope the NLP service serves you well.

 

New Coptic NLP pipeline

The entire tool chain of Coptic Natural Language Processing has been difficult to get running for some: it involves a bunch of command line tools, and special attention needed to be paid to coordinating word division expectations between the tools (normalization, tagging, language of origin detection). In order to make this process simpler, we now offer a Web interface that let’s you paste in Coptic text and run all tools on the input automatically, without installing anything. You can find the interface here:

https://corpling.uis.georgetown.edu/coptic-nlp/

The pipeline is XML tolerant (preserves tags in the input) and there’s also a machine actionable API version for external software to use these resources. Please let the Scriptorium team know if you’re using the pipeline and/or run into any problems.

 

Happy processing!
