It could also be a phrasal lexicon, where the key field is a phrase rather than a single word.
A thesaurus also consists of record-structured data, where we look up entries via non-key fields that correspond to topics.
We can also construct special tabulations (known as paradigms) to illustrate contrasts and systematic variation, as shown in 1.3 for three verbs. At the most abstract level, a text is a representation of a real or fictional speech event, and the time-course of that event carries over into the text itself.
A text could be a small unit, such as a word or sentence, or a complete narrative or dialogue.
Structured collections of annotated linguistic data are essential in most areas of NLP, however, we still face many obstacles in using them.
