Searching the corpus

APLS provides powerful search capabilities for finding linguistic patterns in the interview data. It all starts from the Search page: https://apls.pitt.edu/labbcat/search. Once you create a search, you can export the results in a variety of formats.

If you are looking for information on the Search results page, go to the Exporting data documentation page.

Because the Search page has many options that will be of interest to a variety of different researchers, these documentation pages are more focused on giving users an understanding of the Search page capabilities through “Try it!” tutorials. If you would like to understand the data structure that the Search page relies on, read the Layer typology documentation page.
