FrameNet Resource Grammar Library for GF

Abstract

Abstract. In this paper we present an ongoing research investigating the possibility and potential of integrating frame semantics, particularly FrameNet, in the Grammatical Framework (GF) application grammar development. An important component of GF is its Resource Grammar Library (RGL) that encapsulates the low-level linguistic knowledge about morphology and syntax of currently more than 20 languages facilitating rapid development of multilingual applications. In the ideal case, porting a GF application grammar to a new language would only require introducing the domain lexicon -translation equivalents that are interlinked via common abstract terms. While it is possible for a highly restricted CNL, developing and porting a less restricted CNL requires above average linguistic knowledge about the particular language, and above average GF experience. Specifying a lexicon is mostly straightforward in the case of nouns (incl. multi-word units), however, verbs are the most complex category (in terms of both inflectional paradigms and argument structure), and adding them to a GF application grammar is not a straightforward task. In this paper we are focusing on verbs, investigating the possibility of creating a multilingual FrameNet-based GF library. We propose an extension to the current RGL, allowing GF application developers to define clauses on the semantic level, thus leaving the language-specific syntactic mapping to this extension. We demonstrate our approach by reengineering the MOLTO Phrasebook application grammar.

A semantic grammar for beginning communicators

“…Gruzitis et al [20] propose a general-purpose semantic grammar based on FrameNet in order to facilitate the development of multilingual controlled natural languages applications in GF as an extension of the current RGL. The idea is to provide a frame semantic abstraction layer derived from FrameNet, a shared semantic API over the syntactic RGL.…”

A Type-Theoretical Reduction of Morphological, Syntactic and Semantic Compositionality to a Single Level of Description

“…Because it is geared towards writing NL grammars, it does not offer a selection of different mathematical formalisms to work with, being thus unsuitable for a general (low level) modeling of NL and theories thereof. In addition, it does not concern itself with modeling compositional semantics, although a FrameNet API for GF has been proposed and partly implemented (Gruzitis et al, 2012;Gruzitis and Dannélls, 2017).…”

FrameNet CNL: A Knowledge Representation and Information Extraction Language

“…(Ieva Akuratere had a soloist position) Ieva Akuratere bija Puķu burves amatā [8] (Ieva Akuratere had a Flower fairy position) Ieva Akuratere bija mūziķes un aktrises amatā [5] (… had a musician and actress position) Ieva Akuratere bija deputātes amatā Rīgas domē [ (… had a member position in Riga city council) Ieva Akuratere bija solista amatā Koncertuzvedumā [4] (… had a soloist position in a Concert) Ieva Akuratere bija dziedātājas amatā [3] (… had a singer position) Ieva Akuratere bija triju Zvaigžņu ordeņa virsnieka amatā Latvijā [3] (…had an Honor position in Latvia) This mixed approach allows for creating a convenient user interface, where instance data from the AKR database in Fig. 4 is verbalized in FN-CNL using a light version of [11] producing simple FN-CNL sentences as illustrated in Fig. 6 which further can be arranged in the Curriculum Vitae like document.…”

“…As illustrated in Fig. 1, FN-CNL is a verbalization of the knowledge representation database content (all or partial) by means of some FrameNet verbalization framework, such as [11]. We have implemented FN-CNL verbalization for AKR of 26 frames in Latvian FrameNet and also tested that frame-semantic parsing on this FN-CNL output achieves close to 100% accuracy (which can further be improved by hand-editing human-editable C6.0 generated frame-semantic parsing rules illustrated in Fig.…”
