The Smart Query Editor

In this section you'll learn how to use the Smart Query Editor, a special editor that allows you to compose queries which exploit corpus annotation (things like part-of-speech and lemma).

To open the Smart Query Editor follow these steps:

start Carcass and connect to the server

in the Corpus Selector click on “English”

click on UkWaC 1

At this point the three main query editors (Simple, Smart and Expert) will be open.

Select the Smart query editor.

The Smart query editor will open. If your computer has a small screen it may look like this:

You may want to maximise the application window at this point. Remember also that you can drag the separators to redistribute the space in the application (see the basic tutorial for more info on this).

The application should look more or less like this at this point (you should be able to see all the elements in the Smart Query Editor):

The smart editor contains three Position descriptors, each of these represents the constraint you want to put on a token in your query. You don't need to use all three positions in your query, nor do you need to use all the options offered by the editor.

For instance, let's say that you want to look for examples of the use of the verb “apply” (in all its inflected forms) in the UkWaC corpus.

In the lemma box of position 1 type:

apply

leave everything else untouched and click on Submit.

In a few seconds the results will appear and you'll notice that they also include inflected forms of the verb “apply” (i.e. “applying”, “applied”, “applies”, etc.)

In the next part of the tutorial you'll learn more about the Smart Query Editor.
