[CWB] CQPWeb -- Query restriction using file-level free text metadata

[Hardie, Andrew]

The Restricted Query interface works solely off Classification metadata. The “right way” to search free-text metadata is via the subcorpus-create function, as you suspect.

The difference is that for Classifications, zones of the corpus are predefined and can therefore be used to set up selectable restrictions. With free-text metadata there is no knowing what someone is going to search for – so they have to actually search for what they want i.e. via the subcorpus interface and then once they’ve found a selection of texts, the subcorpus becomes available for restricting queries.

I won’t argue that this will never be clumsy/confusing, however, I submit that this organisation is less clumsy and confusing than it would be to cram both the classification-based restrictions and the (multiple) search forms for free-text metadata all into one web form!

best

Andrew.

Subject: [CWB] CQPWeb -- Query restriction using file-level free text metadata

Hi,

I have a corpus for which I have file level metadata in CQP web. I currently have a couple of classification metadata and a couple of free text metadata.

When I go to the Restricted query interface I get checkboxes for Gender and Location (my classification metadata) but not for the others (Interview ID, Age, Year). Is there any possibility to restrict queries on the basis of those free text metadata on this restricted query interface. I have seen I can create subcorpora, but that seems can be a bit clumsy/confusing for the users (foreign language teachers) I have in mind.

By the way in the "Manage metadata" interface I have seen I can include corpus-level metadata. Are these metadata different from the metadata added at the text-level (that is, using the text id)?

Thanks in advance,
