Exercise CQP 1

Excercise

1. Try out the queries from the tutorial and check the results choosing Frequency breakdown from the drop-down menu in the upper right corner and clicking on Go.

To remember

• Word and lemma are called positional attributes in CQP.
• Positional attributes are attributes on the token level.
• Typical positional attributes of a corpus are: word, lemma and pos (part-of-speech).
• A token is surrounded by square brackets: [].
• Use attribute-value syntax to define the query more closely: [attribute="value"], e.g., [lemma="word"]
• The attribute specifies the type of annotation (word, lemma or part-of-speech), the value specifies the search string.

2. Try out:

   [word="search.+"]
   [word="search.{2}"]
   [word="search.{2,3}"]

   and check the results using Frequency breakdown

3. Execute the querie below and check the results using Frequency breakdown

[word="[a-zA-Z]orse"]

You can also negate a character set using ^ inside the scquare brackets.

[word="[^whm]orse"]

4. Execute the queries and check the result using Frequency breakdown

determiners or nouns:

[pos="DT|NN"]

verbs (including full verbs, auxiliary verbs but no modals)

[pos="V.*"]

full verbs only:

[pos="VV.*"]

full verbs in the past tense

[pos="VV[DN]"]

verbs beginning with under or over

[(pos = "V.*") & (word = "(under|over).+")]
