Automatic Extraction of Semantic Roles in Support Verb Constructions
2021
This paper deals with paraphrastic relations in Italian. In the following sentences: (a) Max strappò delle lacrime a Sara 'Max moved Sara to tears' and (b) Max fece piangere Sara 'Max made Sara cry', the verbs differ syntactically and semantically. Strappare 'tear/rip/wring' is transitive, fare ‘have/make’ is a causative, and piangere 'cry' is intransitive. Despite this, a translation of (a) as (b) is legitimate and therefore (a) is a paraphrase of (b). In theoretical linguistics this raises an issue concerning the relationship between strappare and fare/piangere in Italian, and that in English between move and make. In computational linguistics, can such paraphrases be obtained automatical…
Oggetti interni e reaction objects come nomi predicativi di costrutti a verbo supporto
2011
Analyses regarding clauses with a cognate object (CO), e.g. Alice laughed a scornful laugh, have frequently been based on the query: is the CO an adjunct or a complement? This paper aims to contribute to the debate with an alternative suggestion: the CO functions as a noun predicate licensing the subject, to which it assigns a semantic role, whilst the verb functions as a support (a ‘light verb’). A number of the well-known properties of COs, e.g. certain constraints on the determiner, appear to corroborate this analysis. Clauses with the so-called reaction object (RO), e.g. Alice coughed a scornful laugh, are analyzed as multi-predicative as well: also the RO is a noun predicate which lice…
Cognitive Linguistics as the Underlying Framework for Semantic Annotation
2012
In recent years many attempts have been made to design suitable sets of rules aimed at extracting the semantic meaning from plain text, and to achieve annotation, but very few approaches make extensive use of grammars. Current systems are mainly focused on extracting the semantic role of the entities described in the text. This approach has limitations: in such applications the semantic role is conceived merely as the meaning of the involved entities without considering their context. As an example, current semantic annotators often specify a date entity without any annotation regarding the kind of the date itself i.e. a birth date, a book publication date, and so on. Moreover, these system…
