CQL – search structures
Structures refer to sentences, paragraphs, documents or any other parts or sections into which a corpus might be divided. Another way of saying this is that certain parts of a corpus can be labelled, e.g. direct speech might be labelled using structures to make it possible to limit the search to only direct speech.
Introduction to structures and values
If a corpus has structures (most corpora have them), the structures may or may not have values. Values are used to categorize instances of the same structure.
A corpus with only structures
Structures can be different in each corpus but most corpora will use at least s, p and doc (sentences, paragraphs and documents respectively) as seen in the examples below. To see the list of all structures used in the corpus, go to the Corpus statistics and details page. The page is also useful to check how the common structures are labelled. For example, sentence can use s, sent, sen or snt. This may vary between corpora.
