This article provides definitions of terms used in other articles in this section related to tagging in SPAN sports performance analysis platform.
Tag template
A tag template contains tags and relationships between tags specific to a particular analysis strategy.
Example 1: A team level tag template could feature attack, defence and transitions as categories.
Example 2: A player level tag template could feature the list of players as categories.
Primary category
A
primary category is always attached to any given event in a match. Due
to this, it is mandatory to have primary categories in a tag template to
start tagging.
Example 1: A team-level football/soccer template could consist of goals, assists, shots, etc. as primary categories.
Example 2: For player-level analysis, individual players in a team could serve as primary categories.
Label
Labels
add information to an event that has already been tagged with a primary
category. While adding labels is not compulsory, unlike primary
categories, labels play an important role in providing multi-dimensional
and in-depth analysis.
Example
1: In a template, where team actions could be primary categories (like
attack, defence, transition), players could be tagged as labels. This
means it is optional to add a player tag.
Example
2: In a basketball template, if players were used as primary
categories, the actions made by them such as defensive rebounds, steals,
blocks, etc. could be used as labels. This means it is optional to add
an action tag.
Secondary category
A secondary category is a group of labels. It
is often beneficial for analysts to group the labels for further
analysis. This is where secondary categories come into the picture.
Unlike primary categories, which are directly attached to an event,
secondary categories are indirectly attached by choosing labels from
their groups.
Example 1:
Labels such as "shot off-target" and "shot on-target" can be grouped
into a single secondary category called "shot attempts". Similarly,
labels such as "left corners" and "right corners" could be part of a
secondary category called "corner kick".
Example
2: In basketball, the secondary category "field goal" could consist of
labels such as "successful 2-pointer", "missed 2-pointer", "successful
3-pointer" and a "missed 3-pointer".
