Parallel Entity And Treebank Annotation
نویسندگان
چکیده
We describe a parallel annotation approach for PubMed abstracts. It includes both entity/relation annotation and a treebank containing syntactic structure, with a goal of mapping entities to constituents in the treebank. Crucial to this approach is a modification of the Penn Treebank guidelines and the characterization of entities as relation components, which allows the integration of the entity annotation with the syntactic structure while retaining the capacity to annotate and extract more complex events.

An annotation scheme for Persian based on Autonomous Phrases Theory and Universal Dependencies
A treebank is a corpus with linguistic annotations above the level of the parts of speech. During the first half of the present decade, three treebanks have been developed for Persian either originally or subsequently based on dependency grammar: Persian Treebank (PerTreeBank), Persian Syntactic Dependency Treebank, and Uppsala Persian Dependency Treebank (UPDT). The syntactic analysis of a sen...
متن کاملFrame-Semantic Annotation on a Parallel Treebank
This paper reports on experiments in frame-semantic annotation of a parallel treebank. Selected English and Swedish sentences that contained verbs of motion and communication were annotated independently by two annotators. We found that they assigned the same frame to corresponding sentences in 52% of the cases. This leads us to the conclusion that parallel treebanks can save considerable effor...
متن کاملCorrecting Syntactic Annotation Errors Using a Synchronous Tree Substitution Grammar
This paper proposes a method of correcting annotation errors in a treebank. By using a synchronous grammar, the method transforms parse trees containing annotation errors into the ones whose errors are corrected. The synchronous grammar is automatically induced from the treebank. We report an experimental result of applying our method to the Penn Treebank. The result demonstrates that our metho...
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 کاملArborest – a VISL-Style Treebank Derived from an Estonian Constraint Grammar Corpus
Treebank creation is a very labor-consuming task, especially if the applications intended include machine learning, gold standard parser evaluation or teaching, since only a manually checked syntactically annotated corpus can provide optimal support for these purposes. There are, however, possibilities to make the annotation process (partly) automatic, saving (manual) annotation time and/or all...
