Each instance of <a href="http://sw.opencyc.org/concept/Mx4rpNxmkr2TQdif39yddHO67Q" class="cyc_term">Bicycle_MultiGear</a> is a bicycle built with the ability to change gears. Bicycle-MultiGear rideable transportation device MountableTransporter A <a href="http://sw.opencyc.org/concept/Mx4rwOy_T5wpEbGdrcN5Y29ycA" class="cyc_term">MountableTransporter</a> is a transporter that one `rides' or `rides on' but does not `ride in'. This collection was originally created to enable the following sorts of natural language interpretations. Anyone who is said to `ride' such an object is most likely to be the <a href="http://sw.opencyc.org/concept/Mx4rvVi_RZwpEbGdrcN5Y29ycA" class="cyc_term">driverActor</a>. If someone `rides' a non <a href="http://sw.opencyc.org/concept/Mx4rwOy_T5wpEbGdrcN5Y29ycA" class="cyc_term">MountableTransporter</a> (e.g. a train) is most likely not a <a href="http://sw.opencyc.org/concept/Mx4rvVi_RZwpEbGdrcN5Y29ycA" class="cyc_term">driverActor</a> but a <a href="http://sw.opencyc.org/concept/Mx4rvViM4pwpEbGdrcN5Y29ycA" class="cyc_term">passengers</a>. Positive exemplars include horses, jet skis, motorcycles, bicycles. Negative exemplars include cars, trains, planes. A borderline positive example is a skateboard. When one `rides' a skateboard one is most likely the <a href="http://sw.opencyc.org/concept/Mx4rvVi_RZwpEbGdrcN5Y29ycA" class="cyc_term">driverActor</a>, but, unlike typical <a href="http://sw.opencyc.org/concept/Mx4rwOy_T5wpEbGdrcN5Y29ycA" class="cyc_term">MountableTransporter</a>s, one is also most likely not sitting. 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 seeAlsoURI <code>(<a href="http://sw.opencyc.org/concept/Mx4riWVFR6HJSpaEaHrcWS3MSA" class="cyc_term">seeAlsoURI</a> THING URI)</code> means that a description of the resource identified by URI is likely to contain information pertinent to THING. This predicate is roughly equivalent to rdfs:seeAlso. See Also URI BicycleMarketCategory bicycle market category A type of <a href="http://sw.opencyc.org/concept/Mx4rvVkEW5wpEbGdrcN5Y29ycA" class="cyc_term">PartiallyTangibleProduct</a>. <a href="http://sw.opencyc.org/concept/Mx4rwQCTu5wpEbGdrcN5Y29ycA" class="cyc_term">BicycleMarketCategory</a> is a <a href="http://sw.opencyc.org/concept/Mx4rvVi84ZwpEbGdrcN5Y29ycA" class="cyc_term">ProductTypeByMarketCategory</a>. bilaterally symmetrical object BilaterallySymmetricObject A specialization of <a href="http://sw.opencyc.org/concept/Mx4ro5wCxPfVEdmAAAACs0uFOQ" class="cyc_term">AxisymmetricObject</a> (q.v.). Each instance of <a href="http://sw.opencyc.org/concept/Mx4rvVi5S5wpEbGdrcN5Y29ycA" class="cyc_term">BilaterallySymmetricObject</a> is a (tangible or intangible) spatial object that is symmetric with respect to some bisecting straight line (if the object is planar) or plane (if it's non-planar). In this context, symmetric means that the line or plane divides the object into two equal halves with the same shape (or mirror-image shapes). For example, a <a href="http://sw.opencyc.org/concept/Mx4rmSmWUM7yEdmAAAACs0uFOQ" class="cyc_term">Circle</a>, an isosceles <a href="http://sw.opencyc.org/concept/Mx4rvVjrapwpEbGdrcN5Y29ycA" class="cyc_term">Triangle</a>, a <a href="http://sw.opencyc.org/concept/Mx4rwQwzSJwpEbGdrcN5Y29ycA" class="cyc_term">Cone</a>, and a human body are all bilaterally symmetric objects. If a <a href="http://sw.opencyc.org/concept/Mx4rvVi5S5wpEbGdrcN5Y29ycA" class="cyc_term">BilaterallySymmetricObject</a> <code>OBJ</code> is a one- or two-dimensional planar region, then any bisecting line with respect to which <code>OBJ</code> is symmetric is an axis of symmetry (see <a href="http://sw.opencyc.org/concept/Mx4r4BM6CvVqEdmAAAACs0uFOQ" class="cyc_term">symmetricAxes</a>) of <code>OBJ</code>. If <code>OBJ</code> is a two- or three-dimensional non-planar object that is symmetric with respect to a bisecting plane <code>PLANE</code>, then any straight line with respect to which the space-region intersection of <code>OBJ</code> and <code>PLANE</code> is symmetric is itself an axis of symmetry of <code>OBJ</code>. Thus, a circle has an infinite number of axes of symmetry (viz. any straight line that intersects the circle and passes through its center); an isosceles triangle has exactly one axis of symmetry; a cone has at least one axis of symmetry; and a human body has no axis of symmetry (though it does have three <a href="http://sw.opencyc.org/concept/Mx4r-y7_GvfZEdmAAAACs0uFOQ" class="cyc_term">objectAxes</a> (q.v.)).

Instances are specs of <a href="http://sw.opencyc.org/concept/Mx4rvVjVQJwpEbGdrcN5Y29ycA" class="cyc_term">TransportationDevice</a>, the main function of which is to play the purpose of a vehicle, i.e., to play the role of <a href="http://sw.opencyc.org/concept/Mx4rvViog5wpEbGdrcN5Y29ycA" class="cyc_term">vehicle</a> in transportation events. type of vehicle BT broaderTerm <code>(<a href="http://sw.opencyc.org/concept/Mx4rZOAVeiYGEdqAAAACs2IMmw" class="cyc_term">broaderTerm</a> TERM1 TERM2)</code> means that <code>TERM2</code> is broader than <code>TERM1</code>, in an extremely general sense of "broader". For example, <code>TERM2</code> is, in the relevant sense, broader than <code>TERM1</code> if any of the following hold: <code>TERM2</code> is a collection that subsumes <code>TERM1</code>; <code>TERM2</code> is a collection that has <code>TERM1</code> as an instance; <code>TERM2</code> is a collection, instances of which have instances of the collection <code>TERM1</code> as parts; <code>TERM2</code> has <code>TERM1</code> as a part; This list of reasons for why <code>(<a href="http://sw.opencyc.org/concept/Mx4rZOAVeiYGEdqAAAACs2IMmw" class="cyc_term">broaderTerm</a> TERM1 TERM2)</code> could hold is not exhaustive, but it should give a good indication of how general the <a href="http://sw.opencyc.org/concept/Mx4rZOAVeiYGEdqAAAACs2IMmw" class="cyc_term">broaderTerm</a> relation actually is. SpatiallyDisjointObjectType type of object whose instances do not physically overlap A collection of collections and a specialization of <a href="http://sw.opencyc.org/concept/Mx4rvVirnZwpEbGdrcN5Y29ycA" class="cyc_term">ObjectType</a> (q.v.). Each instance of <a href="http://sw.opencyc.org/concept/Mx4rpPHhAOB1EdqAAAACs6hRXg" class="cyc_term">SpatiallyDisjointObjectType</a> is a collection C of spatial things (see <a href="http://sw.opencyc.org/concept/Mx4rvVjpUZwpEbGdrcN5Y29ycA" class="cyc_term">SpatialThing</a>), where each of the spatial things in C is spatially disjoint with the other spatial things in C. For example, the collection <a href="http://sw.opencyc.org/concept/Mx4rvVjaoJwpEbGdrcN5Y29ycA" class="cyc_term">Dog</a> is an instance of <a href="http://sw.opencyc.org/concept/Mx4rpPHhAOB1EdqAAAACs6hRXg" class="cyc_term">SpatiallyDisjointObjectType</a>, since dogs do not spatially overlap. Even pregnant dogs do not spatially overlap the pups they bear; rather, pregnant dogs contain their unborn pups. Other instances of <a href="http://sw.opencyc.org/concept/Mx4rpPHhAOB1EdqAAAACs6hRXg" class="cyc_term">SpatiallyDisjointObjectType</a> include <a href="http://sw.opencyc.org/concept/Mx4rwVGrQ5wpEbGdrcN5Y29ycA" class="cyc_term">LatitudeLine</a>, <a href="http://sw.opencyc.org/concept/Mx4rvW4n1pwpEbGdrcN5Y29ycA" class="cyc_term">CompactDisc_Audio</a>, and <a href="http://sw.opencyc.org/concept/Mx4rwR7UWZwpEbGdrcN5Y29ycA" class="cyc_term">PlanetaryBody</a>.

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 href="http://sw.opencyc.org/concept/Mx4rwHLvC5wpEbGdrcN5Y29ycA" class="cyc_term">WheeledTransportationDevice</a> is a specialization of <a href="http://sw.opencyc.org/concept/Mx4rvVjU_5wpEbGdrcN5Y29ycA" class="cyc_term">LandTransportationDevice</a>.

This collection includes not only many instances of <a href="http://sw.opencyc.org/concept/Mx4rwLzhaZwpEbGdrcN5Y29ycA" class="cyc_term">TransportationDevice_Vehicle</a>, but also non-self-powered devices such as <a href="http://sw.opencyc.org/concept/Mx4rvVjo0JwpEbGdrcN5Y29ycA" class="cyc_term">Bicycle</a>s and <a href="http://sw.opencyc.org/concept/Mx4rwP1mLpwpEbGdrcN5Y29ycA" class="cyc_term">Wagon</a>s. wheeled vehicle WheeledTransportationDevice product ManufacturedGoods The collection of all <a href="http://sw.opencyc.org/concept/Mx4rvVkH_ZwpEbGdrcN5Y29ycA" class="cyc_term">Artifact</a>s that are made or processed in large-scale industrial operations for distribution (normally sale) to agents outside the manufacturing organization. This includes manufactured stuff, e.g. Finlandia vodka; refined ore, e.g. iron; otherwise procesed natural material, e.g. cut diamonds, as well as manufactured objects. This collection excludes handicrafts; privately made stuff, e.g. moonshine; and other artifacts produced by one or a few people on a small scale. Device-UserPowered user-powered device A specialization of <a href="http://sw.opencyc.org/concept/Mx4rvViT7ZwpEbGdrcN5Y29ycA" class="cyc_term">MusclePoweredDevice</a>. Each instance of <a href="http://sw.opencyc.org/concept/Mx4rvViU95wpEbGdrcN5Y29ycA" class="cyc_term">Device_UserPowered</a> is an artifact deliberately designed to perform a particular function, and one which depends upon the physical efforts of the user to perform that function in part or in whole. A paradigm example would be a bicycle. However, the definition also leaves room for some counterintuitive cases -- for example, combs and forks also qualify as user-powered devices. Borderline cases would be devices which require effort on the part of the user to perform part of the function, but not all of it. For example, many gas-powered lawnmowers have to be pushed by hand, but use an internal combustion engine to impart the necessary velocity to the cutting surfaces. <a href="http://sw.opencyc.org/concept/Mx4rvVjo0JwpEbGdrcN5Y29ycA" class="cyc_term">Bicycle</a> is a specialization of <a href="http://sw.opencyc.org/concept/Mx4rwHLvC5wpEbGdrcN5Y29ycA" class="cyc_term">WheeledTransportationDevice</a>, <a href="http://sw.opencyc.org/concept/Mx4rwOy_T5wpEbGdrcN5Y29ycA" class="cyc_term">MountableTransporter</a>, <a href="http://sw.opencyc.org/concept/Mx4rvViU95wpEbGdrcN5Y29ycA" class="cyc_term">Device_UserPowered</a>, and <a href="http://sw.opencyc.org/concept/Mx4rwIPuOJwpEbGdrcN5Y29ycA" class="cyc_term">Device_UserControlled</a>.
