Extending a Verb-lexicon Using a Semantically Annotated Corpus
نویسندگان
چکیده
This paper describes the association of an hierarchical verb lexicon, VerbNet, with a semantically annotated corpus, the Proposition Bank. It focuses on comparisons of the syntactic coverage of the two resources as a method of evaluating their correspondence. Both VerbNet and PropBank have explicit syntactic frames associated with each verb, which allowed an automatic mapping between the two resources for almost 50,000 instances. We aim at both a quantitative and qualitative analysis of how the syntactic frames in VerbNet reflect the syntactic frames that actually occurred in PropBank. VerbNet accounts for about 78% exact matches to these frames and 81% somewhat more relaxed matches.

Using Prepositions To Extend A Verb Lexicon
This paper presents a detailed account of prepositional mismatch between our handcrafted verb lexicon and a semantically annotated corpus. The analysis of these mismatches allows us to re ne the lexicon and to create a more robust resource capable of better semantic predictions based on the verb-preposition relations.
متن کاملA new semantically annotated corpus with syntactic-semantic and cross-lingual senses
In this article, we describe a new sense-tagged corpus for Word Sense Disambiguation. The corpus is constituted of instances of 20 French polysemous verbs. Each verb instance is annotated with three sense labels: (1) the actual translation of the verb in the english version of this instance in a parallel corpus, (2) an entry of the verb in a computational dictionary of French (the Lexicon-Gramm...
متن کاملUsing inheritance and coreness sets to improve a verb lexicon harvested from FrameNet
We investigate two aspects of the annotation scheme underlying the FrameNet semantically annotated corpus — the inheritance relation on semantic types with its corresponding links between semantic roles of increasing granularity, and the specification of coreness sets of related semantic roles — against the background of our ongoing effort to harvest a lexicon of verb entries for deep parsing. ...
متن کاملMaking Virtue of Necessity: A Verb Lexicon
We describe the verb lexicon of OpenWordNet-PT, a wordnetlike resource for (mostly Brazilian) Portuguese and a series of experiments that we designed to extend its coverage. These experiments include checking online lists of most common verbs, checking corpora freely available such as the Bosque-UD (the Bosque corpus annotated with Universal Dependencies) and especially checking a dictionary of...
متن کاملEvaluating Complement-Modifier Distinctions in a Semantically Annotated Corpus
We evaluate the extent to which the distinction between semantically core and non-core dependents as used in the FrameNet corpus corresponds to the traditional distinction between syntactic complements and modifiers of a verb, for the purposes of harvesting a widecoverage verb lexicon from FrameNet for use in deep linguistic processing applications. We use the VerbNet verb database as our gold ...
