++h(3, "lemmatization") Lemmatization
+
++aside("Examples")
+    |   In English, this means:#[br]
+    |  #[strong Adjectives]: happier, happiest → happy#[br]
+    |  #[strong Adverbs]: worse, worst → badly#[br]
+    |  #[strong Nouns]: dogs, children → dog, child#[br]
+    |  #[strong Verbs]: writes, wirting, wrote, written → write
+
+
+p
+    |  A lemma is the uninflected form of a word. The English lemmatization
+    |  data is taken from #[+a("https://wordnet.princeton.edu") WordNet].
+    |  Lookup tables are taken from
+    |  #[+a("http://www.lexiconista.com/datasets/lemmatization/") Lexiconista].
+    |  spaCy also adds a #[strong special case for pronouns]: all pronouns
+    |  are lemmatized to the special token #[code -PRON-].
+
++infobox("About spaCy's custom pronoun lemma", "⚠️")
+    |  Unlike verbs and common nouns, there's no clear base form of a personal
+    |  pronoun. Should the lemma of "me" be "I", or should we normalize person
+    |  as well, giving "it" — or maybe "he"? spaCy's solution is to introduce a
+    |  novel symbol, #[code -PRON-], which is used as the lemma for
+    |  all personal pronouns.
+
++h(3, "sentence-boundary") Sentence boundary detection
+
+p
+    |  Sentence boundaries are calculated from the syntactic parse tree, so
+    |  features such as punctuation and capitalisation play an important but
+    |  non-decisive role in determining the sentence boundaries. Usually this
+    |  means that the sentence boundaries will at least coincide with clause
+    |  boundaries, even given poorly punctuated text.

-    p A "lemma" is the uninflected form of a word. In English, this means:
-
-    +list
-        +item #[strong Adjectives]: The form like "happy", not "happier" or "happiest"
-        +item #[strong Adverbs]: The form like "badly", not "worse" or "worst"
-        +item #[strong Nouns]: The form like "dog", not "dogs"; like "child", not "children"
-        +item #[strong Verbs]: The form like "write", not "writes", "writing", "wrote" or "written"
-
-    p
-        |  The lemmatization data is taken from
-        |  #[+a("https://wordnet.princeton.edu") WordNet]. However, we also add a
-        |  special case for pronouns: all pronouns are lemmatized to the special
-        |  token #[code -PRON-].
-
-    +infobox("About spaCy's custom pronoun lemma")
-        |  Unlike verbs and common nouns, there's no clear base form of a personal
-        |  pronoun. Should the lemma of "me" be "I", or should we normalize person
-        |  as well, giving "it" — or maybe "he"? spaCy's solution is to introduce a
-        |  novel symbol, #[code -PRON-], which is used as the lemma for
-        |  all personal pronouns.
