About Lucid scores

Multi-state features in Lucid may be scored using seven possible scores:

A more in depth explanation of each score type is available. Below outlines a summary of each.

Absent score icon Absent – the state does not occur in the entity.

common score icon Common – the state occurs commonly (or always) in the entity.

rare score iconRare – the state occurs rarely in the entity.

uncertain score icon Uncertain – it is not known whether the state occurs in the entity or not

common misinterpreted score icon Common and Misinterpreted – the state does not occur in the entity, but it could be commonly misinterpreted that it does.

rare misinterpreted score icon Rare and Misinterpreted – the state does not occur in the entity, but it could be misinterpreted that it does, though only rarely.

not scoped score icon Not Scoped – all states of the feature are not scored and will not be scored for the entity.

Numeric features in Lucid may be scored using four possible scores:

Numeric score not set icon  Numeric absent – the numeric feature does not occur in the entity

Numeric score set icon Normal – the numeric feature occurs normally in the entity

Numeric score set icon Misinterpreted – the numeric feature does not occur in the entity, but it could be misinterpreted that it does.

Numeric score set icon Uncertain – the value for the numeric feature for the entity is not known.

not scoped score icon Not Scoped – the numeric feature is not scored and will not be scored for the entity

Note

Normal, Misinterpreted and Uncertain numeric scores are set and distinguished via the Numeric Score Dialog not within the item trees.

Once a numeric Feature has been scored the icon changes to bold.

Scoring

Scoring multi-state features in the Features and Entities panels

Lucid Builder Score Mode button and Score Mode toggle buttonThe simplest way to score entities and features in the Lucid Builder is to click the Enable Score Mode Toggle score mode icon  button  to the right of the Entities panel. If the currently active selected item is an entity, score boxes will appear in the Features tree; if the currently active selected item is a state, score boxes will appear in the Entities tree. At any time you can flip between scoring entities for a state, or states for an entity, by clicking on the Change Score Mode Toggle score mode type icon button.

Tip

If a Feature node is selected in the Features tree instead of a state node, clicking on the Enable Score Mode button will place the Entities tree into score mode but no score boxes will appear. In this case, select a state in the Features tree. Similarly, if nodes of the Features tree are closed so no states are visible, clicking on Enable Score Mode with an entity selected will place the Features tree into score mode but no score boxes will appear. In this case, open nodes in the Features tree to display some states.

Lucid Builder Score toolbarWhen the Lucid Builder is placed in score mode, a series of buttons providing the different possible scores will appear to the right hand side of the Entities panel. Choose the appropriate score by clicking on one of the score buttons, then click on one or more score boxes in the Features or Entities panels.

Scores can be changed at any time, simply by choosing a different score and clicking on a scored box again.

Note that the Not Scoped score can only be applied to all states of a feature. If the Not Scoped score is selected, clicking on the score box for any state will set all states of the feature to Not Scoped. Conversely, if the states of a feature are currently coded using Not Scoped, giving any other score to one state will cause all other states to be given the Absent score.

Propagate scores icon Score propagation

If your key has an Entity hierarchy it is possible to have the Lucid Builder propagate an applied score to a parent entity to propagated down to all the children. The score propagation option can be toggled on or off depending on your needs via the Propagate score mode button Propagate scores icon on the Score toolbar. Alternatively, if you only wish to enable score propagation temporarily you can hold down the Control (ctrl) key when you apply a score to a parent Entity.

Warning

Any score applied to the parent Entity, while Score Propagation is enabled, will overwrite any scores that have already been applied to the child Entities. You can override the propagated score with another score value at anytime. If you mistakenly override scores to child Entities use Undo (ctrl + z) to revert back to the original scores.

Scoring multi-state features in the Score Spreadsheet

Scoring in the Features or Entities trees provides a view of all state scores for one entity, or all entity scores for one state. The Spreadsheet Scoring panel allows you to see all scores arranged into a handy spreadsheet, with entities as columns and states as rows.

To use Spreadsheet score mode, click the Spreadsheet Scoring tab at the base of the tree panels.

To score, select the scoring type needed from the scoring buttons to the right, then click the scoring box corresponding to the entity and feature you wish to score.

The feature list can be expanded or contracted by clicking the plus or minus buttons located next to the parent items or by using the expand all and collapse all buttons in the main toolbar.

Spreadsheet “bulk” Scoring

Where common scores apply to a number of entities listed next to each other or character states you can “bulk score” these by using the shift key. For example, hold down the shift key and score the desired cell, move to the last cell across where you wish to apply the scores to and continue to hold down the shift key and score the cell. All cells between the selected cells will take on this new score value. This same technique can be also used to un-score or change scores in cells. It can also be applied across multiple rows.

Warning

Undo is not available for this action.

Display settings in the Spreadsheet Scoring panel are set through the Builder Preferences dialog box.

See the topic Configuring the Lucid Builder for more information.

Scoring numeric features

In score mode in the Features or Entities trees or in the Spreadsheet Scoring panel, numeric features are shown with a hash symbol in the score box Numeric score set icon. Clicking on a numeric feature’s score box will open the Numeric Scores panel. In this panel, enter the values that the entity can have for the feature.

Four values may be entered – for the outside minimum, normal minimum, normal maximum and outside maximum. Think of the outside scores as rare ranges and the inside as a normal range. For instance, a plant may have leaves that are normally 10-20 mm long, but are occasionally as low as 8 mm or as high as 25 mm. In text, this is often written (8-)10-20(-25). In the dialog box, use 8 for Outside Minimum, 10 for Normal Minimum, 20 for Normal Maximum and 25 for Outside Maximum.

It is not necessary for all these values to be different. The following table gives some examples of valid scores:

Valid Numeric Scores table example

Note

Sometimes a taxon will need to be scored with a disjunct range. For instance, consider a plant that may have 5 or 10-15 petals. In this case, click on the Add Numeric Record button in the Numeric Features panel. A new row will be inserted into the Numeric Scores panel. Score the two (or more) disjunct ranges in separate rows:

Numeric Scoring disjunct range example
Numeric Scoring disjunct range example

The Score Type column in the Numeric Scores panel can be used to assign numeric scores of type NormalUncertain and Misinterpreted.

Use Normal when the values entered are normal for the entity being scored. This is equivalent to the Normally Present and Rarely Present scores for a multi-state feature.

Use the Misinterpreted score type when you are scoring a numeric range for a Feature that may be misinterpreted as being present. For example, a key to insects may include a species that has very small antennae, but large antenna-like structures that could be misinterpreted by a user as being antennae. In this case record the length of the real antennae using a Normal numeric score, and record the length of the antenna-like structures using a Misinterpreted numeric score:

Numeric Scoring Misinterpreted example
Numeric Scoring Misinterpreted example

In this way, a key builder can preempt a mistake made by a user measuring the length of the pseudo-antennae instead of the real antennae.

Use the Uncertain score type to record that a value for a numeric feature is currently unknown.

For more information on the way Misinterpreted and Uncertain scores are handled in the Lucid Player, see How to use the Lucid scores.

Numeric Precision

It is recommend that you maintain a consistent precision level through the scoring of numerics. Take the following example,

 Festuca occidentalis, with scored anther lengths of (1) 1.5 – 2.5 (3) mm

A user of the key enters the following value for the anthers in the Player of 0.5-0.6

Because of the difference between precision on the first compared anther value (1) for Festuca occidentalis, Lucid rounds the 0.5 to 1, leaving Festuca occidentalis in the entities remaining. If the precision level was set to (1.0) then no rounding would occur and Festuca occidentalis would be discarded as a match.
