Sections in the corpus [corpus]¶

documents.sections

Abstract sections [corpus]¶

documents.sections:abstract

or

documents.sections(name == "abstract")

First is faster.

Abstract sections in the test set [corpus]¶

documents(set == "test").sections:abstract

This assumes that documents have a feature with key set that denote the set to which it pertains.

All genes and taxa [section]¶

layer:genes | layer:taxa

or

layer('ne-tpe' == "gene" or 'ne-type' == "species")

The first is faster. It assumes that all gene annotations are in a layer named genes, and that all taxon annotations are in a layer taxa. The annotations are given in the following order: first genes in standard order, then taxa in standard order.

The second assumes that annotations have a feature names ne-type containing the named entity type of the annotation. The annotations are given in standard order regardless of the type.

All words included in a sentence [annotation]¶

inside:words

This assumes that the context element is an annotation representing a sentence. It also assumes that all words are in a layer named words.

All verbs [section]¶

layer:words(pos ^= "V")

or

layer:words(pos =~ "^V")

Both assume all word annotations are in a layer named words and have a feature with key pos whose value denote its POS. First should be slightly faster.

All syntactic dependencies [section]¶

relations:dependencies.tuples

This assumes syntactic dependencies are in a relation named dependencies.

Words that are subject [section]¶

relations:dependencies.tuples(label == "SUBJ:V-N").args:dependent

If you insist to check they are subjet to verbs:

relations:dependencies.tuples(label == "SUBJ:V-N" and args:head.pos ^= "V").args:dependent

Subject of a verb [annotation]¶

tuple:dependencies:head(label == "SUBJ:V-N").args:dependent
