Every instance of <a href="http://sw.opencyc.org/concept/Mx4rGGsQIeqUEdqTjAACs6hPlA" class="cyc_term">IntelligentAgentActivity</a> is an action, each of whose "doers" (see <a href="http://sw.opencyc.org/concept/Mx4rwP1HmJwpEbGdrcN5Y29ycA" class="cyc_term">doneBy</a> and <a href="http://sw.opencyc.org/concept/Mx4rQ9dkLFWAQdeQE7cXOq70Qg" class="cyc_term">animateDoer</a>s) is either an <a href="http://sw.opencyc.org/concept/Mx4rvVinb5wpEbGdrcN5Y29ycA" class="cyc_term">IntelligentAgent</a> or a group of such agents (i.e. a <a href="http://sw.opencyc.org/concept/Mx4rvVjmoJwpEbGdrcN5Y29ycA" class="cyc_term">Group</a> all of whose members are intelligent agents). Specializations of this collection include <a href="http://sw.opencyc.org/concept/Mx4rvViN65wpEbGdrcN5Y29ycA" class="cyc_term">HumanActivity</a> and <a href="http://sw.opencyc.org/concept/Mx4rvVjVMpwpEbGdrcN5Y29ycA" class="cyc_term">Reading</a>. Brewing brewing The activity of producing beer. skilled activity This is the collection of collections of activities which require some specialized skill to perform--i.e., to play any role which is a specPred of <a href="http://sw.opencyc.org/concept/Mx4rwP1HmJwpEbGdrcN5Y29ycA" class="cyc_term">doneBy</a>. So, all skilled activities are learned, but not all learned activities are skilled. For instance, <a href="http://sw.opencyc.org/concept/Mx4rvVi0gpwpEbGdrcN5Y29ycA" class="cyc_term">WalkingOnTwoLegs</a> is an instance of <a href="http://sw.opencyc.org/concept/Mx4rvm8XOpwpEbGdrcN5Y29ycA" class="cyc_term">LearnedActivityType</a> but not an instance of <a href="http://sw.opencyc.org/concept/Mx4rvbVrl5wpEbGdrcN5Y29ycA" class="cyc_term">SkilledActivityType</a>. Since every normal person learns to walk, it requires no special skill. In contrast, <a href="http://sw.opencyc.org/concept/Mx4rvYn_nZwpEbGdrcN5Y29ycA" class="cyc_term">Juggling</a> is an instance of <a href="http://sw.opencyc.org/concept/Mx4rvbVrl5wpEbGdrcN5Y29ycA" class="cyc_term">SkilledActivityType</a>, for most people do not know how to juggle. SkilledActivityType Wikipedia Article URL (<a href="http://sw.opencyc.org/concept/Mx4rNv0nbm4TTjOp7yhmnzOyqg" class="cyc_term">wikipediaArticleURL</a> THING URL) means that in <a href="http://sw.opencyc.org/concept/Mx4rtqXA6OC8QdiWC72DuLJdUw" class="cyc_term">Wikipedia_WebSite</a> THING is described by an article located at URL wikipediaArticleURL Brewing brewing The activity of producing beer. Pretty String (<a href="http://sw.opencyc.org/concept/Mx4rwLSVCpwpEbGdrcN5Y29ycA" class="cyc_term">prettyString</a> TERM STRING) means that STRING is the English word or expression (sequence of words) commonly used to refer to TERM. The predicate <a href="http://sw.opencyc.org/concept/Mx4rwLSVCpwpEbGdrcN5Y29ycA" class="cyc_term">prettyString</a> is used by the code which generates CycL to English paraphrases, but its applicability is not restricted to this use. prettyString A specialization of <a href="http://sw.opencyc.org/concept/Mx4rvViAyZwpEbGdrcN5Y29ycA" class="cyc_term">equals</a> and a <a href="http://sw.opencyc.org/concept/Mx4rvWKHbpwpEbGdrcN5Y29ycA" class="cyc_term">CycLReformulatorConstant</a> that relates pairs of <a href="http://sw.opencyc.org/concept/Mx4rwE2kWpwpEbGdrcN5Y29ycA" class="cyc_term">CycLClosedDenotationalTerm</a>s. <a href="http://sw.opencyc.org/concept/Mx4rwTvAxJwpEbGdrcN5Y29ycA" class="cyc_term">rewriteOf</a> is, in a sense, a "directional" version of <a href="http://sw.opencyc.org/concept/Mx4rvViAyZwpEbGdrcN5Y29ycA" class="cyc_term">equals</a>. <code>(<a href="http://sw.opencyc.org/concept/Mx4rwTvAxJwpEbGdrcN5Y29ycA" class="cyc_term">rewriteOf</a> FAVORED-TERM DISFAVORED-TERM)</code> means that (1) <code>FAVORED-TERM</code> and <code>DISFAVORED-TERM</code> denote the same thing, and (2) <code>FAVORED-TERM</code> is deemed worthy of being privileged over <code>DISFAVORED-TERM</code> in the following senses: assertions made on <code>DISFAVORED-TERM</code> will be propagated to <code>FAVORED-TERM</code>, and whenever possible attempts to reason about <code>DISFAVORED-TERM</code> will be transformed into attempts to reason about <code>FAVORED-TERM</code>. The propagated assertions will differ from the original assertions only in that the propagated assertions will be the result of substituting <code>FAVORED-TERM</code> for <code>DISFAVORED-TERM</code> wherever <code>DISFAVORED-TERM</code> occurs in the original assertions. Note that substitution does not happen in the opposite direction. That is, assertions containing <code>FAVORED-TERM</code> will not propagate to <code>DISFAVORED-TERM</code>. One common use of <a href="http://sw.opencyc.org/concept/Mx4rwTvAxJwpEbGdrcN5Y29ycA" class="cyc_term">rewriteOf</a> is that in which <code>FAVORED-TERM</code> is a syntactically simpler term than <code>DISFAVORED-TERM</code>. For example, <code>FAVORED-TERM</code> may contain fewer nested terms that denote <a href="http://sw.opencyc.org/concept/Mx4rvVxAsJwpEbGdrcN5Y29ycA" class="cyc_term">Function_Denotational</a>s than does <code>DISFAVORED-TERM</code>. (<a href="http://sw.opencyc.org/concept/Mx4rwTvAxJwpEbGdrcN5Y29ycA" class="cyc_term">rewriteOf</a> <a href="http://sw.opencyc.org/concept/Mx4rvVjxdJwpEbGdrcN5Y29ycA" class="cyc_term">UnitedStatesNavy</a> (<a href="http://sw.opencyc.org/concept/Mx4rwGGrfpwpEbGdrcN5Y29ycA" class="cyc_term">NavyFn</a> <a href="http://sw.opencyc.org/concept/Mx4rvVikKpwpEbGdrcN5Y29ycA" class="cyc_term">UnitedStatesOfAmerica</a>)) is a good example of this common sort of use. Note that <a href="http://sw.opencyc.org/concept/Mx4rwTvAxJwpEbGdrcN5Y29ycA" class="cyc_term">rewriteOf</a> expresses a strictly conventional notion of "directional" equality. Pragmatic considerations, not ontology, will dictate which term is chosen to occur as the privileged (left-hand side) term in a <a href="http://sw.opencyc.org/concept/Mx4rwTvAxJwpEbGdrcN5Y29ycA" class="cyc_term">rewriteOf</a> assertion. Thus, in the example the fact that simpler terms are generally easier to use (remember, manipulate, etc.) dictates that <a href="http://sw.opencyc.org/concept/Mx4rvVjxdJwpEbGdrcN5Y29ycA" class="cyc_term">UnitedStatesNavy</a> should be a rewrite of (<a href="http://sw.opencyc.org/concept/Mx4rwGGrfpwpEbGdrcN5Y29ycA" class="cyc_term">NavyFn</a> <a href="http://sw.opencyc.org/concept/Mx4rvVikKpwpEbGdrcN5Y29ycA" class="cyc_term">UnitedStatesOfAmerica</a>), and not vice versa. Rewrite Of rewriteOf TemporalObjectType temporal object type A specialization of <a href="http://sw.opencyc.org/concept/Mx4rvVirnZwpEbGdrcN5Y29ycA" class="cyc_term">ObjectType</a> (q.v.) whose instances are all and only those collections that are temporally object-like. A collection <code>COL</code> is temporally object-like just in case it generally holds that any proper purely temporal parts (see <a href="http://sw.opencyc.org/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA" class="cyc_term">timeSlices</a>) of an instance of <code>COL</code> is not itself an instance of <code>COL</code>. More precisely, a collection <code>COL</code> is an instance of <a href="http://sw.opencyc.org/concept/Mx4rvViq35wpEbGdrcN5Y29ycA" class="cyc_term">TemporalObjectType</a> just in case it satisfies the following: For any distinct <code>OBJ1</code> and <code>OBJ2</code>, if <code>(<a href="http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> OBJ1 COL)</code> and <code>(<a href="http://sw.opencyc.org/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA" class="cyc_term">timeSlices</a> OBJ1 OBJ2)</code>, then not <code>(<a href="http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> OBJ2 COL)</code>. For example, none of the proper time-slices of a <a href="http://sw.opencyc.org/concept/Mx4rvVjyV5wpEbGdrcN5Y29ycA" class="cyc_term">CalendarYear</a> is itself a calendar year. Likewise for <a href="http://sw.opencyc.org/concept/Mx4rvViYBpwpEbGdrcN5Y29ycA" class="cyc_term">TakingAStep</a>. So <a href="http://sw.opencyc.org/concept/Mx4rvVjyV5wpEbGdrcN5Y29ycA" class="cyc_term">CalendarYear</a> and <a href="http://sw.opencyc.org/concept/Mx4rvViYBpwpEbGdrcN5Y29ycA" class="cyc_term">TakingAStep</a> are both instances of <a href="http://sw.opencyc.org/concept/Mx4rvViq35wpEbGdrcN5Y29ycA" class="cyc_term">TemporalObjectType</a>. Conversely, a proper time-slice of a given <a href="http://sw.opencyc.org/concept/Mx4rvVisWZwpEbGdrcN5Y29ycA" class="cyc_term">Date</a> might itself be a <a href="http://sw.opencyc.org/concept/Mx4rvVisWZwpEbGdrcN5Y29ycA" class="cyc_term">Date</a> (e.g. an hour has minutes and seconds as time-slices); so <a href="http://sw.opencyc.org/concept/Mx4rvVisWZwpEbGdrcN5Y29ycA" class="cyc_term">Date</a> is not a temporal-object-type. See <a href="http://sw.opencyc.org/concept/Mx4rvVitN5wpEbGdrcN5Y29ycA" class="cyc_term">TemporalStuffType</a> for the disjoint notion of being temporally stuff-like. producing a batch of an alcoholic beverage Making a batch of some alcoholic beverage such as beer, wine, etc. ProducingAnAlcoholicBeverage brewing (MakingFn Beer) wikipediaArticleName (<a href="http://sw.opencyc.org/concept/Mx4rTv-jk9SPTXa991kk5mAvHg" class="cyc_term">wikipediaArticleName</a> THING NAME) means that in <a href="http://sw.opencyc.org/concept/Mx4rtqXA6OC8QdiWC72DuLJdUw" class="cyc_term">Wikipedia_WebSite</a> THING is described by an article with the title NAME Wikipedia Article Name
