Influence of Treebank Design on Representation of Multiword Expressions
نویسندگان
چکیده
Multiword Expressions (MWEs) are important linguistic units that require special treatment in many NLP applications. It is thus desirable to be able to recognize them automatically. Semantically annotated corpora should mark MWEs in a clear way that facilitates development of automatic recognition tools. In the present paper we discuss various corpus design decisions from this perspective. We propose guidelines that should lead to MWE-friendly annotation and evaluate them on numerous sentence examples. Our experience of identifying MWEs in the Prague Dependency Treebank provides the base for the discussion and examples from other languages are added whenever appropriate.

Annotation of Multiword Expressions in the Prague Dependency Treebank
We describe annotation of multiword expressions in the Prague Dependency Treebank, using several automatic pre-annotation steps. We use subtrees of the tectogrammatical tree structures of the Prague dependency treebank to store representations of the multiword expressions in the dictionary and pre-annotate following occurrences automatically. We also show a way to measure reliability of this ty...
متن کاملUse of Coreference in Automatic Searching for Multiword Discourse Markers in the Prague Dependency Treebank
The paper introduces a possibility of new research offered by a multi-dimensional annotation of the Prague Dependency Treebank. It focuses on exploitation of the annotation of coreference for the annotation of discourse relations expressed by multiword expressions. It tries to find which aspect interlinks these linguistic areas and how we can use this interplay in automatic searching for Czech ...
متن کاملFinalising Multiword Annotations in PDT
We describe the annotation of multiword expressions and multiword named entities in the Prague Dependency Treebank. This paper includes some statistics of data and inter-annotator agreement. We also present an easy way to search and view the annotation, even if it is closely connected with deep syntactic treebank.
متن کاملSyntactic Identification of Occurrences of Multiword Expressions in Text using a Lexicon with Dependency Structures
We deal with syntactic identification of occurrences of multiword expression (MWE) from an existing dictionary in a text corpus. The MWEs we identify can be of arbitrary length and can be interrupted in the surface sentence. We analyse and compare three approaches based on linguistic analysis at a varying level, ranging from surface word order to deep syntax. The evaluation is conducted using t...
متن کاملExtracting Verbal Multiword Data from Rich Treebank Annotation
The PARSEME Shared Task on automatic identification of verbal multiword expressions aims at identifying such expressions in running texts. Typology of verbal multiword expressions, very detailed annotation guidelines and gold-standard data for as many languages as possible will be provided. Since the Prague Dependency Treebank includes Czech multiword expression annotation, it was natural to ma...
