<h3>Keyword Tagging Component Ouput</h3>

Change "Ouput" to "Output"

---

docs/docs/Release-Notes.md line 60 at r1 (raw file):

- Updated the Keyword Tagging Component to generate output in the same format as the  Transformer Tagging Component. For
  example, the output properties used to take the form `[INPUT] TRIGGER WORDS` and `[INPUT] TRIGGER WORDS OFFSET`:

Square brackets usually mean optional. For example, this is from the ln man page: ln [OPTION]... [-T] TARGET LINK_NAME. We normally use angle brackets to represent a place holder. The "Trigger Support" section use both of these conventions:
<prop_name>=<prop_value1>[;<prop_value2>...]

---

docs/docs/Release-Notes.md line 80 at r1 (raw file):

- Notice that in the above example the new output properties include the word `TRAVEL`. If trigger words are detected
  for other tags, such as `FINANCIAL` and `VEHICLE`, those words will be used in separate `TRIGGER WORDS` and
  `TRIGGER WORDS OFFSET` output properies.

Change "properies" to "properties"
