    • Indicator A pressure gauge; a water gauge, as for a steam boiler; an apparatus or instrument for showing the working of a machine or moving part
    • Indicator (Mach) A telltale connected with a hoisting machine, to show, at the surface, the position of the cage in the shaft of a mine, etc.
    • Indicator (Mach) An instrument which draws a diagram showing the varying pressure in the cylinder of an engine or pump at every point of the stroke. It consists of a small cylinder communicating with the engine cylinder and fitted with a piston which the varying pressure drives upward more or less against the resistance of a spring. A lever imparts motion to a pencil which traces the diagram on a card wrapped around a vertical drum which is turned back and forth by a string connected with the piston rod of the engine. See Indicator cardbelow).

    • n indicator One who indicates or points out; that which points out, directs, or reports, as a grade-post on a railroad, the pointer on a steam-gage, etc. It is used in compound names to describe a number of gaging or indicating appliances: as, leak-indicator, speed-indicator, etc.
    • n indicator Specifically— A steam (cylinder) pressure-gage. It is an apparatus for recording the variations of pressure or vacuum in the cylinder of a steam-engine. The accompanying cut represents a type of the indicator. The pipe with the stop-cock is screwed to the cylinder so that when the cock is opened the pressure of the steam within may enter the cylinder above, press the piston upward against the action of a spring constructed to give a definite resistance in pounds per square inch, and cause the lever-arm to rise and mark on the hollow cylinder at the left a vertical trace, the altitude of which measures the pressure. A card or a sheet of paper may be fitted to this cylinder, and the trace be made on the paper. The hollow cylinder is free to revolve, if drawn by the loose cord hanging from it. To operate the indicator, the cord is connected with some moving part of the engine so that a single stroke of the piston causes the cylinder and the card to revolve once (the return being secured by a spring) as the pencil makes one mark. Since the pencil-mark is timed to one stroke of the engine, the resulting curved line on the card gives a graphic report of the pressure or vacuum of the steam during one complete stroke. Such graphic curves are called indicator-diagrams, the marked card being called an indicator-card. See indicator-diagram, under diagram
    • n indicator The dial and pointer of a signal-telegraph used on private lines, where rapidity of delivery of the messages is not important. It consists of a dial having the letters of the alphabet printed upon it, and a pointer that traverses the circle, pausing before the letters of the word transmitted, thus spelling out the message. See telegraph.

    • n indicator In railroad signaling, a device for informing the leverman in a signal-cabin that a train is about to start from the station and indicating which track it will take; in its broadest sense, any appliance for displaying, in the signal-cabin, the condition of a track or of all the tracks in a yard, the position of the signals, semaphores, switches, and signal-lamps, the trains at rest, or moving, or about to enter or leave any block, etc. The indicator may be a number on a drop-plate, a disk or banneret, or a miniature signal-arm, and it may give information by its appearance or disappearance or by its position. It may also give a signal by means of a bell. An indicator may be operated from a distant station or cabin by a push-button, or it may be automatic, or it may be controlled by a train through a track-circuit.
    • n indicator In mining, an appearance of the surface of the ground which shows the presence of a mineral underneath.
    • n indicator Naval: An apparatus used in conjunction with a transmitter, operated by mechanical or electrical means for signaling orders from a central position to the various places on a war-ship at which the orders are to be executed. The transmitter is manipulated by the operator in the central station or in the conning-tower to show any desired order, and the same order is shown on one or more indicators connected to the transmitter by wires or shafting. A range-indicator shows the range of the object at which the guns are to be fired; a battle-order indicator shows various orders such as ‘commence firing,’ ‘load with shell,’ etc. An apparatus to show at a convenient Point the position of any mechanism: as, a revolution-indicator to show the direction of revolution of the main engines; a rudder -indicator, to show the position of the helm or rudder; a turret-indicator, to show the position of the turret guns with reference to the fore-and-aft line of the ship; etc.

Discarding peace over all the sea and land.

E inquieti, e, scorgendo--cola` soltanto il boia,
Si volgono all'usciuolo--scintillanti di gioia.
"Mastro Spaghi" by Ferdinando Fontana
Never reject a homely-sounding phrase,
That your whole meaning easily conveys,
For one made current by some courtly wit
Which barely indicates a shade of it,
Or which—for probably it so may fall—
Does not express what you would mean at all.

Our tour of link prediction algorithms starts with the mainstreaming class of algorithms, the so-called similarity-based algorithms 1, which are further classified into three categories according to the information used by the similarity indices: local indices, global indices and quasi-local indices.
Link Prediction in Complex Networks: A Survey
Here we adopt the simplest method, where 20 similarity indices are classified into three categories: the former 10 are local indices, followed by 7 global indices, and the last 3 are quasi-local indices, which do not require global topological information but make use of more information than local indices.
