Abstract
This paper discusses the use of text corpora in syntactic research, and how to search
for example sentences in corpora. During the past few decades, widely divergent
views have been expressed as to the value of corpora in syntactic argumentation. It
is argued in the paper that this disagreement stems from different views as to the
subject of linguistic research. The paper also discusses various problems that arise in
the interpretation of the information extracted from corpora - especially in drawing
conclusions from the silence of the texts on certain constructions. The main section
of the paper discusses the possibilities of searching for certain syntactic constructions
in different types of Icelandic corpora; raw untagged text, PoS tagged text, and text
where the major syntactic constituents and syntactic functions have been identified.
Data-driven PoS taggers have now been trained on Icelandic texts, and it is shown
that due to the inflectional character of Icelandic and the richness of the tagset, the re-
sulting PoS tagging is very effective in the search for various syntactic constructions.
