==Overview==

Almost all of the '''semantic tagging''' that's taking place in [[Directory:Centiare|Centiare]] will fall into two types of scenarios -- '''[[Centiare:Relations|Relations]]''' and '''[[Centiare:Attributes|Attributes]]'''.

Suppose you were writing an article about the city of Berlin, Germany.  You could easily type out in the article that "'''Berlin is the capital of the unified country of Germany, and there are nearly 3.4 million people living in its metropolitan area.'''"  That's really good encyclopedia information.

However, if someone searches for the exact phrase "capital of Germany" or "population of Berlin", your sentence that happens to answer both of those questions would not be returned by either of those particular text searches.   What we hope to see in Centiare is active use of the semantic tagging process, so that such information is more likely to be found -- by either humans typing in commands, or machines programmed to find information.  

So, the essence of semantic tagging is, somewhere in the Berlin article text, or in an infobox, or even in an addendum at the bottom of the article, if you want to create a semantic link that describes a "capital-relationship", this is done by writing:

 <nowiki>[[capital of::Germany]]</nowiki>

Note the use of two (2) colons in succession.  You've just created a semantic tag '''Relation'''.

Furthermore, if you want to create a semantic link that describes a "population-attribute", this is done by writing:

 <nowiki>[[population:=3396990]]</nowiki>

Note the use of the colon and equal sign in succession.  You've just created a semantic tag '''Attribute'''. (By the way, don't add commas to  [[Attribute:population|population]]; this attribute has a [[Type:Integer]], which means it will be displayed as 3,396,990.)

==Custom Tags==
<div id="newarticletext" style="background: white; border: 2px solid blue; margin: 8px 100px; padding: 8px 16px">
Consult first with [[User_talk:Snerfling|Snerfling]] before attempting to create any custom '''''[[Special:attributes|attributes]]''''' and/or '''''[[Special:relations|relations]]'''''. There may be tags already in place to fit your needs; if new tags ''are'' needed for a specific application, seek  assistance in proper design and utilization.

'''Incorrectly designed and/or documented tags are subject to deletion.'''

===Ordinal Attributes===

There are many advantages to using [[Centiare:ordinal identifier|ordinal identifier]]s (Centiare convention is numbers) to further differentiate between certain related attributes.

The two general cases are:
*When attribute '''''values''''' are variable/non-standard e.g. job titles vs movie titles, which means one searches on attributes themselves, not attribute ''values''. In other words, while [[Centiare:Tutorial#Use_uniform_titles_when_identifying_any_Key_Person|job titles]] may vary between different key people, such as president, vice-president, director, etc., there is only one (the original) "Gone With the Wind". Here's an example from the [[Special:Attributes|attributes list]]:

<pre>
Key Person1 Title
Key Person2 Title
</pre>

*When attributes have '''''relations''''' to other attributes e.g. [[Attribute:Key_Person1|key person]] <-> [[Attribute:Key_Person1_Title|job title]]. Expanding upon the example shown above, job titles can be associated with the respective individuals who hold those positions:

<pre>
Key Person1
Key Person1 Title
Key Person2
Key Person2 Title
Key Person3
Key Person3 Title
Key Person4
Key Person4 Title
</pre>


In this way, [[Attribute:Association|professional associations]] don't normally require ordinal identifiers, unless at some point there are secondary attribute relations. For example association <-> committee, association <-> year joined, etc.

===Relations===

Concepts such as [[Relation:Subject Interest|subject interest]]s can also be semantically tagged as ''[[Centiare:relations|relations]]'', since common Directory or Main pages can be interlinked to multiple users via [[Centiare:ASK|ASK]] queries (see [[Skiing]] for an example).

==Standards==
Centiare is beginning to standardize the use of tags in certain specified areas. It is expected these guidelines will be used to form a consistent approach towards classifying information to increase both usability and searching.

==Search Queries==

Centiare uses a parser function called '''[[Centiare:ASK|ASK]]''' to perform free-form queries. ASK provides a ready complement to the [[Centiare:Search Triple|Search Triple]] query-by-form facility.

When people use the [[Special:SearchTriple|"Search Triple"]] feature in Centiare, they will have utmost confidence and success in finding the articles they are looking for, if they correctly use the search forms, and you've correctly tagged your articles for semantic searching.

The possibilities for this are literally limitless, for both businesses and individuals.  Imagine conducting a search for a male, born in Michigan between 1965 and 1968, who has interests in both skiing and poker.  Do you think that would be easy with MySpace, Wikipedia, or Google?  Fat chance.  But on Centiare, it will be a [[Directory:Gregory_J._Kohs|piece of cake]], if you [[Centiare:Learning ASK|learn to use]] the '''ASK''' function.
