Preliminaries

Before starting, you may want to have a quick look at the documentation and visualization system introduction.

The online documentation is stored on GitHub, a service for projects using the Git version control system. To contribute, you need a GitHub account.

If you already have a GitHub account, just make sure you are logged in before moving on. If you do not, please go to https://github.com/join and create an account first. (It’s free, only takes a minute, and there’s a reasonable privacy policy in place.)

After logging in to GitHub, see the following:

How to edit the documentation
How to file bug reports, feature requests, etc.

Editing

(Note: the following instructions are for project members. If you are not a member, see here.)

To get started with editing the materials, first read the brief style guidelines and the file format description below. Then, the easiest way to edit the materials is to use the online editing features provided by GitHub. If you prefer to use your own text editor or need to make larger changes, you may wish to use the git version control system and work on the files on your own computer.

Style guidelines

See also the guidelines for language-specific documentation. To maintain the consistency of the documentation, please follow these guidelines:

All types / labels (POS tags, feature names/values, relation labels) are in constant width font. To achieve this, use either a documentation link (see below), or backticks in Markdown (e.g. `nsubj`) or <code> in HTML (e.g. <code>nsubj</code>).
The first mention of any type other than the one that is the focus of the page (the titular one) is linked to the relevant page of documentation. For example, on the page for nsubj, write “`nsubj`” and “[case]()”. Repeated mentions of the same type may be optionally be linked (if they are too far apart, it makes sense to hyperlink again, but it does not make sense to highlight several occurrences in the same paragraph)
Examples in a foreign language should be followed by an English translation, which is not italicized but it is enclosed in quotes, e.g. der Mann “the man”.
- Note that Markdown processing converts straight ASCII quotes (") to typographic (directional) quotation marks (“”), which should be used for all quotes.
Examples given in a foreign script are only italicized if it is Cyrillic or Greek. (In some scripts Italics don’t look nice and the foreign script highlights the word anyway.) They should be immediately followed by a Latin-based transliteration, which is in italics. The transliteration is separated from the original script by a slash, which is not italics.
- Иван лучший танцор / Ivan lučšij tancor “Ivan is the best dancer”
- राम इवान से भी बेहतर है / rāma ivāna se bhī behatara hai “Ram is even better than Ivan”
To emphasize part of an example, use the <b> tag. For example, _<b>Which</b> car_ renders as follows: Which car.
- To emphasize text that is not part of an example, use _light emphasis_ (rendering as light emphasis) or **heavy emphasis** (heavy emphasis), but not the <b> tag.
If an in-line example shall contain a verbose translation, it is also italics and without quotes, separated by the non-italics abbreviation “lit.” Multi-word expressions that correspond to one token in the original language are joined by a hyphen. The verbose translation is followed by a fluent English translation in its usual format.
- Seděla na lavičce pod mostem. lit. She-sat on bench under bridge. “She was sitting on a bench under the bridge.”
If it is necessary / expedient to identify the language of the example, it is either identified in plain English (such as German ich bin gekommen “I have come”) or the ISO 639 language code in square brackets is used as shortcut (such as [de] ich bin gekommen “I have come”).

File format

The online documentation is generated from a simple format that largely resembles plain text. Similarly, the embedded visualizations are generated from representations in the Stanford Dependency or CoNLL-X formats, each of which can be created and edited manually or copied in from the output of relevant tools.

For example, the following:

A copula is the relation between the complement of a copular verb and the copular verb to be (only). (We normally take a copula as a dependent of its complement.)

Bill is an honest man
cop(man, is)

Ivan is the best dancer
nsubj(dancer-5, Ivan-1)
cop(dancer-5, is-2)
det(dancer-5, the-3)
amod(dancer-5, best-4)

The copula be is not treated as the head of a clause, but rather the dependent of a lexical predicate, as exemplified above.

is generated from this input:

A copula is the relation between the complement of a copular verb and
the copular verb *to be* (only).  (We normally take a copula as a dependent of its
complement.)

~~~ sdparse
Bill is an honest man
cop(man, is)
~~~

~~~ sdparse
Ivan is the best dancer
nsubj(dancer-5, Ivan-1)
cop(dancer-5, is-2)
det(dancer-5, the-3)
amod(dancer-5, best-4)
~~~

The copula *be* is not treated as the
head of a clause, but rather the dependent of a lexical predicate, as exemplified above.

The input is primarily in the Markdown format (see also GitHub Markdown Basics and GitHub Flavored Markdown), which can be mostly written like plain text and mixed freely with inline HTML. The only exception is the format used for embedding visualizations, which is supported as an extension specific to this project. To embed a visualization represented in the Stanford Dependency format, simply wrap it in lines with ~~~ sdparse and ~~~, as in the example above. (Or, correspondingly, wrap in HTML tags <div class="sd-parse"> and </div>)

The documentation system also supports linking of pages in collections using a compact syntax: for example, [u-dep/aux]() expands into the following link: u-dep/aux

For more detail, you can see the documentation for the Markdown syntax and embedded visualizations. However, we believe that the formats are simple enough to learn by example and by doing, and suggest to proceed directly to the next section (editing).

Editing online

GitHub provides basic online editing functionality. The interface looks something like this:

To get started, the only relevant parts are the large black edit area and the “Cancel” and “Commit changes” buttons at the bottom.

To give this a quick try, click on the following link: edit sandbox document. This opens a “sandbox” document in a new tab. After testing it out, feel free to either cancel without saving your changes, or save them into the version control system using the “Commit changes” button. You can see the resulting document here (reload to see changes, and please note it may take some time for the changes to show up.)

For experimenting with the system, we recommend using the sandbox document instead of the “real” documents.

To edit the actual documentation, first find the page you’re interested in. For example, to navigate to the documentation for the English language dobj (direct object) dependency:

Start from the homepage (http://universaldependencies.org/)
Click on the “English relations index” link (go to http://universaldependencies.org/en/dep/index.html)
Click on the “dobj” link (go to http://universaldependencies.org/en/dep/dobj.html)

Then, edit and save your changes:

Click on the “edit page” link on the top
Make your changes in the GitHub editor
(Optional: add a message describing your changes in the “Commit changes” box)
Click on “Commit changes”

Finally, wait a moment for your revisions to the documentation to be compiled (normally no more than 10 seconds) and reload the documentation page to make sure they look right.

That’s all you need to get started. If you have any issues using the system, please see the troubleshooting section below.

Using Git

As an alternative to using the online editing features, you can also edit the materials using the Git version control system as described in this section.

If you are not previously familiar with Git, please see GitHub instructions on setup and basic use. The rest of this section assumes that you have git set up and are working on a terminal in a unix-like environment. For other use cases, please see GitHub documentation.

The project materials are found in the repository https://github.com/universaldependencies/docs. To check out these materials from GitHub, run the following command:

git clone git@github.com:UniversalDependencies/docs.git

If successful, this will create the subdirectory docs/ containing the data of the repository in your current directory. You can then edit the files in the repository normally, using your favorite text editor. After completing a set of changes, you can commit the changes with the command

git commit -a

and push them to the shared online repository with

git push

if you see the error error: failed to push some refs, it’s likely that others pushed changes to the shared online repository while you were working. You can retrieve these changes and merge them with yours with the command

git pull

This covers the very basics only. Please see the extensive materials available online at GitHub and elsewhere for details.

Technical note: please do not commit anything into the gh-pages branch of the repository. The files in this branch are autogenerated and will be overwritten on any changes to the repository. (If this note makes no sense to you, don’t worry – you cannot do this by accident.)

Filing issues

To file bug reports, feature requests, suggestions for improvement, etc., you can use the project issue tracker: https://github.com/universaldependencies/docs/issues.

The issue tracker is open to members and non-members alike, and can be used to let (other) project members know of any issue with the online documentation, including technical problems, mistakes in the descriptions or examples, or suggestions for how to improve any aspect of the project.

Non-members

Although only members of this project can directly edit the online materials, you do not need to be a member to contribute. Non-members can either file issues on the project bug tracker, or submit proposed changes as pull requests.

Troubleshooting

Issue: when running locally, the system gives the error message cannot load such file – jekyll-redirect-from.

Solution: install the ruby gem jekyll-redirect-from, for example with gem install jekyll-redirect-from.

Issue: when running locally, the system gives the error message CodeRay::Scanners could not load plugin.

Solution: check that CodeRay is not running. The _config.yml option kramdown: enable_coderay: false should disable coderay.

If you have any trouble with the system, just ask Sampo (sampo.pyysalo@gmail.com) or Filip (ginter@cs.utu.fi) or open an issue at http://github.com/universaldependencies/docs/issues.
