AQL currently includes the following operators:
|For non-terminal nodes, precedence is determined by the right-most and left-most terminal children. In corpora with multiple segmentations the layer on which consecutivity holds may be specified with
|For specific sizes of precedence spans,
.n,m can be used, e.g.
.3,4 - between 3 and 4 token distance; the default maximum distance for
.* is 50 tokens. As above, segmentation layers may be specified, e.g.
|Same as precedence, but in either order. In corpora with multiple segmentations the layer on which consecutivity holds may be specified with
|Like indirect precedence in either order. The form
^n,m can be used, e.g.
^3,4 - between 3 and 4 token distance; the default maximum distance for
^* is 50 tokens. As above, segmentation layers may be specified, e.g.
|A specific edge type may be specified, e.g.
>secedge to find secondary edges. Edge labels are specified in brackets, e.g.
>[func="OA"] for an edge with the function 'object, accusative'
|For specific distance of dominance,
>n,m can be used, e.g.
>3,4 - dominates with 3 to 4 edges distance
|part of sub-corpus
|Left attribute is part of a sub-corpus having the attribute of the right-hand side. For specific distance range in the sub-corpus hierarchy,
@n,m can be used.
|Applies when two annotations cover the exact same span of tokens
|Applies when one annotation covers a span identical to or larger than another
|Both elements span an area beginning with the same token
|Both elements span an area ending with the same token
|A = B
|The value of the annotation or token A is identical to that of B (this operator does not bind, i.e. the nodes must be connected by some other criteria too)
|A ≠ B
|The value of the annotation or token A is different from B (this operator does not bind, i.e. the nodes must be connected by some other criteria too)
|labeled pointing relation
|A labeled, directed relationship between two elements. Annotations can be specified with
|indirect pointing relation
|An indirect labeled relationship between two elements. The length of the chain may be specified with
->LABEL n,m for relation chains of length n to m
|Specifies the amount of directly dominated children that the searched node has
|True for two attributes that belong to the same node
The following operators have been available in the legacy version ANNIS3, but are not yet implemented in the newest ANNIS version.
|Overlap, but only on the left or right side
|common parent node
|common ancestor node
|Specifies the length of the span of tokens covered by the node
|Specifies that the node is not dominated by any other node within its namespace s
