<h1>1. Introduction</h1>
<p>
MorphoDiTa: Morphological Dictionary and Tagger is an open-source tool for
morphological analysis of natural language texts. It performs morphological
analysis, morphological generation, tagging and tokenization and is distributed
as a standalone tool or a library, along with trained linguistic models. In the
Czech language, MorphoDiTa achieves state-of-the-art results with a throughput
around 10-200K words per second. MorphoDiTa is a free software under
<a href="http://www.mozilla.org/MPL/2.0/">Mozilla Public License 2.0</a> and the linguistic models
are free for non-commercial use and distributed under
<a href="http://creativecommons.org/licenses/by-nc-sa/4.0/">CC BY-NC-SA</a> license, although for some
models the original data used to create the model may impose additional
licensing conditions. MorphoDiTa is versioned using <a href="http://semver.org/">Semantic Versioning</a>.

<h1>5. MorphoDiTa User's Manual</h1>
<p>
In a natural language text, the task of morphological analysis is to assign for
each token (word) in a sentence its lemma (cannonical form) and
a part-of-speech tag (POS tag). This is usually achieved in two steps:
a morphological dictionary looks up all possible lemmas and POS tags for each
word, and subsequently, a morphological tagger picks for each word the best
lemma-POS tag candidate. The second task is called a disambiguation.
</p>
<p>
MorphoDiTa also performs these two steps of morphological analysis: It first
outputs all possible pairs of lemma and POS tag for each token. Consequently,
the optimal combination of lemmas and POS tags is selected for the words in
a sentence using an algorithm described in
<a href="http://aclweb.org/anthology//E/E09/E09-1087.pdf">Spoustová et al. 2009</a>.
</p>
<p>
Like any supervised machine learning tool, MorphoDiTa needs a trained linguistic model.
This section describes the available language models and also the commandline
tools and interfaces. The C++ library is described elsewhere, either in
MorphoDiTa API Tutorial or in MorphoDiTa API Reference.

<h3>5.1.3. MorfFlex CZ 2.0 Morphological System</h3>
<p>
The MorfFlex CZ 2.0 uses a so-called <i>PDT-C tag set</i>, which is an evolution
of the original <i>PDT tag set</i> devised by Jan Hajič
(<a href="http://books.google.cz/books?id=sB63AAAACAAJ">Hajič 2004</a>).
The tags are positional with 15 positions corresponding to part of speech,
detailed part of speech, gender, number, case, etc. (e.g. <code>NNFS1-----A----</code>).
Different meanings of same lemmas are distinguished and additional comments can
be provided for every lemma meaning. The lemma itself without the comments and
meaning specification is called a <i>raw lemma</i>. The following examples
illustrate this:
</p>
<ul>
<li><code>Japonsko_;G</code> (raw lemma: <code>Japonsko</code>)
</li>
<li><code>se_^(zvr._zájmeno/částice)</code> (raw lemma: <code>se</code>)
</li>
<li><code>tvořit_:T</code> (raw lemma: <code>tvořit</code>)
</li>
</ul>

<h3>5.1.4. PDT-C 1.0 Train/Dev/Test Split</h3>
<p>
The PDT-C corpus consists of four datasets, but some of them do not have
an official train/dev/test split. We therefore used the following split:
</p>
<ul>
<li>PDT dataset is already split into train, dev (<code>dtest</code>), and test (<code>etest</code>).
</li>
<li>PCEDT dataset is a translated version of the Wall Street Journal, so we used
the usual split into train (sections 0-18), dev (sections 19-21), and test
(sections 22-24).
</li>
<li>PDTSC and FAUST datasets have no split, so we split it into dev (documents
with identifiers ending with 6), test (documents with identifiers ending with 7),
and train (all the remaining documents).
</li>
</ul>

<h3>5.1.5. Model Variants</h3>
<p>
Apart from the primary model, which predicts all the 15 tag positions and processed
texts with diacritics, we also provide several variants:
</p>
<ul>
<li><code>pos_only</code>: Instead of all 15 tag positions, the model predicts only the first 2,
which contain the coarse and detailed POS, plus the full lemma, while being
circa 15 times faster than the primary model.
<p></p>
</li>
<li><code>no_dia</code>, <code>no_dia-pos_only</code>: The forms (during morphological analysis,
generation, and tagging) have the diacritical marks stripped; however, the
lemmas do include them. Useful for processing texts without diacritics.
</li>
</ul>

Czech morphological dictionary and the Czech tagger is trained on
<a href="http://ufal.mff.cuni.cz/pdt3.0">PDT 3.0</a>. The morpholodical derivator

Czech models work in MorphoDiTa version 1.9 or later.
</p>
<p>
Apart from MorfFlex CZ dictionary, a prefix guesser and statistical guesser
are implemented and can be optionally used when performing morphological analysis.
</p>
<p>
Czech models are versioned according to the version of the MorfFlex CZ
morphological dictionary used, the version format is <code>YYMMDD</code>, where <code>YY</code>,
<code>MM</code> and <code>DD</code> are two-digit representation of year, month and day,
respectively. The latest version is 161115.
</p>
<p>
Compared to Featurama <a href="http://sourceforge.net/projects/featurama/">http://sourceforge.net/projects/featurama/</a>
(state-of-the-art Czech tagger implementation), the models are 5 times faster
and 10 times smaller.

<h3>5.2.3. Czech Morphological System</h3>
<p>
In the Czech language, MorphoDiTa uses Czech morphological system by
Jan Hajič (<a href="http://books.google.cz/books?id=sB63AAAACAAJ">Hajič 2004</a>).
In this system, which we call <i>PDT tag set</i>, the tags are positional with 15
positions corresponding to part of speech, detailed part of speech, gender,
number, case, etc. (e.g. <code>NNFS1-----A----</code>). Different meanings of same
lemmas are distinguished and additional comments can be provided for every
lemma meaning. The lemma itself without the comments and meaning specification
is called a <i>raw lemma</i>. The following examples illustrate this:
</p>
<ul>
<li><code>Japonsko_;G</code> (raw lemma: <code>Japonsko</code>)
</li>
<li><code>se_^(zvr._zájmeno/částice)</code> (raw lemma: <code>se</code>)
</li>
<li><code>tvořit_:T</code> (raw lemma: <code>tvořit</code>)
</li>
</ul>
