<h2>Documentation</h2>
<p>The functions in this module take the same parameters and return the same values as their counterparts in <a href="pattern-en.html">pattern.en</a>. Refer to the documentation there for more details. </p>
<h3>Noun singularization & pluralization</h3>
<p>For Spanish nouns there is <span class="inline_code">singularize()</span> and <span class="inline_code">pluralize()</span>. The implementation is slightly less robust than the English version (accuracy 94% for singularization and 78% for pluralization).</p>
<div class="example">
<pre class="brush:python; gutter:false; light:true;">>>> from pattern.es import singularize, pluralize
>>>
>>> print singularize('gatos')
>>> print pluralize('gato')
gato
gatos </pre></div>
<h3>Verb conjugation</h3>
<p>For Spanish verbs there is <span class="inline_code">conjugate()</span>, <span class="inline_code">lemma()</span>, <span class="inline_code">lexeme()</span> and <span class="inline_code">tenses()</span>. The lexicon for verb conjugation contains about 600 common Spanish verbs, composed by Fred Jehle. For unknown verbs it will fall back to a rule-based approach with an accuracy of about 84%. </p>
<p>Spanish verbs have more tenses than English verbs. In particular, the plural differs for each person, and there are additional forms for the <span class="inline_code">FUTURE</span> and <span class="inline_code">CONDITIONAL</span> tense, the <span class="inline_code">IMPERATIVE</span> and <span class="inline_code">SUBJUNCTIVE</span> mood and the <span class="inline_code">PERFECTIVE</span> aspect:</p>
<div class="example">
<pre class="brush:python; gutter:false; light:true;">>>> from pattern.es import conjugate
>>> from pattern.es import INFINITIVE, PRESENT, PAST, SG, SUBJUNCTIVE, PERFECTIVE
>>>
>>> print conjugate('soy', INFINITIVE)
>>> print conjugate('soy', PRESENT, 1, SG, mood=SUBJUNCTIVE)
>>> print conjugate('soy', PAST, 3, SG)
>>> print conjugate('soy', PAST, 3, SG, aspect=PERFECTIVE)
ser
sea
era
fue </pre></div>
<p>For <span class="inline_code">PAST</span> tense + <span class="inline_code">PERFECTIVE</span> aspect we can also use <span class="inline_code">PRETERITE</span>. For <span class="inline_code">PAST</span> tense + <span class="inline_code">IMPERFECTIVE</span> aspect we can also use <span class="inline_code">IMPERFECT</span>:</p>
<div class="example">
<pre class="brush:python; gutter:false; light:true;">>>> from pattern.es import conjugate
>>> from pattern.es import IMPERFECT, PRETERITE
>>>
>>> print conjugate('soy', IMPERFECT, 3, SG)
>>> print conjugate('soy', PRETERITE, 3, SG)
era
fue </pre></div>
<p> The <span class="inline_code">conjugate()</span> function takes the following optional parameters:</p>

<p>Instead of optional parameters, a single short alias, or <span class="inline_code">PARTICIPLE</span> or <span class="inline_code">PAST+PARTICIPLE</span> can also be given. With no parameters, the infinitive form of the verb is returned.</p>
<p class="small"><span style="text-decoration: underline;">Reference</span><span>: Jehle, F. (2012). <em>Spanish Verb Forms</em>. Retrieved from: </span><span><a class="noexternal" style="color: inherit;" href="http://users.ipfw.edu/jehle/verblist.htm" target="_blank">http://users.ipfw.edu/jehle/verblist.htm</a>.</span></p>
<h3>Attributive & predicative adjectives </h3>
<p>Spanish adjectives inflect with an <span class="inline_code">-o</span>, <span class="inline_code">-a</span> , <span class="inline_code">-os</span>, <span class="inline_code">-as</span>, or <span class="inline_code">-es</span> suffix (e.g., <em>curioso</em> → <em>los gatos curiosos</em>) depending on gender. You can get the base form with the <span class="inline_code">predicative()</span> function, or vice versa with <span class="inline_code">attributive()</span>. For predicative, a statistical approach is used with an accuracy of 93%. For attributive, you need to supply gender (<span class="inline_code">MALE</span>, <span class="inline_code">FEMALE</span>, <span class="inline_code">NEUTRAL</span> and/or <span class="inline_code">PLURAL</span>).</p>
<div class="example">
<pre class="brush:python; gutter:false; light:true;">>>> from pattern.es import attributive, predicative
>>> from pattern.es import FEMALE, PLURAL
>>>
>>> print predicative('curiosos')
>>> print attributive('curioso', gender=FEMALE)
>>> print attributive('curioso', gender=FEMALE+PLURAL)
curioso
curiosa
curiosas </pre></div>
<h3>Parser</h3>
<p>For parsing there is <span class="inline_code" style="font-family: Courier, monospace; font-size: 12px;">parse()</span>, <span class="inline_code">parsetree()</span> and <span class="inline_code" style="font-family: Courier, monospace; font-size: 12px;">split()</span>. The <span class="inline_code">parse()</span> function annotates words in the given string with their part-of-speech <a class="link-maintenance" href="mbsp-tags.html">tags</a> (e.g., <span class="postag">NN</span> for nouns and <span class="postag">VB</span> for verbs). The <span class="inline_code">parsetree()</span> function takes a string and returns a tree of nested objects (<span class="inline_code">Text</span> → <span class="inline_code">Sentence</span> → <span class="inline_code">Chunk</span> → <span class="inline_code">Word</span>). The <span class="inline_code">split()</span> function takes the output of <span class="inline_code">parse()</span> and returns a <span class="inline_code">Text</span>. See the <span class="inline_code">pattern.en</span> documentation (<span class="link-maintenance" style="color: #78aaff;"><a style="color: #8caaff; outline-style: none !important; outline-width: initial !important; outline-color: initial !important;" href="pattern-en.html#tree">here</a></span>) how to manipulate <span class="inline_code">Text</span> objects. </p>
<div class="example">
<pre class="brush:python; gutter:false; light:true;">>>> from pattern.es import parse, split
>>>
>>> s = parse('El gato negro se sienta en la estera.')
>>> for sentence in split(s):
>>> print sentence
Sentence('El/DT/B-NP/O gato/NN/I-NP/O negro/JJ/I-NP/O'
'se/PRP/B-NP/O sienta/VB/B-VP/O'
'en/IN/B-PP/B-PNP la/DT/B-NP/I-PNP estera/NN/I-NP/I-PNP ././O/O')</pre></div>
<p>The parser is trained on the Spanish portion of <a href="http://www.lsi.upc.edu/~nlp/wikicorpus/" target="_blank">Wikicorpus </a> using 1.5M words from the tagged sections 10,000–15,000. The accuracy is around 92%. The original <a href="http://www.lsi.upc.edu/~nlp/SVMTool/parole.html" target="_blank">Parole</a> tagset is mapped to <a href="mbsp-tags.html">Penn Treebank</a> tagset. If you need to work with the original tags you can also use <span class="inline_code">parse()</span> with an optional parameter <span class="inline_code">tagset="parole"</span>.</p>

<h3>Sentiment analysis</h3>
<p>There's no <span class="inline_code">sentiment()</span> function for Spanish yet.</p>
