The paper presents an ongoing research that aims at OWL ontology authoring and verbalization using a deterministic controlled natural language (CNL) that would be as natural and intuitive as possible. Moreover, we focus on a multilingual CNL interface to OWL by considering both highly analytical and highly synthetic languages (namely, English and Latvian).(More)
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(More)
We present the creation of an English-Swedish FrameNet-based grammar in Grammatical Framework. The aim of this research is to make existing framenets computationally accessible for multilingual natural language applications via a common semantic grammar API, and to facilitate the porting of such grammar to other languages. In this paper, we describe the(More)
When an OWL ontology, together with SWRL rules, is defined or verbalized in controlled natural language (CNL) it is important to ensure that the meaning of CNL statements will be unambiguously (predictably) interpreted by both human and machine. CNLs that are based on analytical languages (namely, English) impose a number of syntactic restrictions that(More)
Controlled natural languages (mostly English-based) recently have emerged as seemingly informal supplementary means for OWL ontology authoring, if compared to the formal notations that are used by professional knowledge engineers. In this paper we present by examples controlled Latvian language that has been designed to be compliant with the state of the(More)
This paper presents a currently bilingual but potentially multilingual FrameNet-based grammar library implemented in Grammatical Framework. The contribution of this paper is twofold. First, it offers a methodological approach to automatically generate the grammar based on semantico-syntactic valence patterns extracted from FrameNet-annotated corpora.(More)
Re-engineering of successful pre-OWL ontologies or other formal ER or UML system models towards OWL DL compliance opens new possibilities in ontology debugging, enabled by the formal semantics and automated reasoners developed for OWL DL, such as RacerPro and others. Meanwhile the transformation of pre-OWL ontologies to OWL DL is a challenging and(More)
