“…But it soon turned out that writing such grammars from scratch for each application was untenable, as each application had to reimplement morphology and syntax. To relieve this task, the GF Resource Grammar Library (RGL) (Ranta, 2009) was created, inspired by the resource grammars of CLE (Core Language Engine) (Rayner et al, 2000). The current RGL includes 30 languages, implementing the inflectional morphology and a comprehensive part of the syntax of each language.…”

“…The key operations provided by the run-time library are parsing, generation, and (by combining the former two) translation. The GF run-time library is also available as a web service, which can be used to create interactive natural language web applications (Bringert et al, 2009;. Examples can be seen in Figures 6 and 7.…”

This paper describes a grammar-based translation system built by a company for a paying customer. The system uses a multilingual grammar for English, Finnish, German, Spanish, and Swedish written in GF (Grammatical Framework). The grammar covers a corpus of technical texts in Swedish, describing properties of places and objects related to accessibility by disabled people. This task is more complex than most previous GF tasks, which have addressed controlled languages. The main goals of the paper are: (1) to find a grammar architecture and workflow for domain-specific grammars on real data (2) to estimate the quality reachable with a reasonable engineering effort (3) to assess the cost of grammar-based translation and its commercial viability. IntroductionWhile statistical methods dominate in assimilation (browsing quality) translation, grammars have been argued to have a niche in dissemination (publication quality). The rationale is that such tasks are often domain-specific and need high precision rather than wide coverage. A recent effort in this direction was the European MOLTO project (Hallgren et al., 2012), which developed tools for such tasks building on the grammar formalism GF (Grammatical Framework, (Ranta, 2011)).MOLTO also built showcases for a few domains (mathematics (Saludes and Xambó, 2011), paintings (Damova et al., 2014), business models (Davis et al., 2012), and touristic phrases (Ranta et al., 2012)). But these showcases were all dealing with CNL (controlled natural language), which was defined by the grammar writers and designed to be processable by formal grammars. The present paper takes a step beyond these research prototypes, as the language to be translated is not controlled, but naturally written by different authors at different times. The system was ordered by a paying customer to solve a real problem. Also the size of the language is larger than in the mentioned MOLTO applications.The task was to create a translation system for a web service documenting the accessibility to different sites, e.g. whether they can be visited by wheelchair users 1 . The service provider had a set of text templates written in Swedish, for instance stating that the width of the door is [X]. These templates had previously been translated by professional translators to English and partly to other languages. Also Google translate had been used for some languages.For quality reasons, Google translate was deemed unsatisfactory by the customer. Manual translation was problematic because of its high cost and low speed: the system is updated by new texts continuously, and their translations should appear without delays. Therefore the customer contracted a company 2 to build an automatic system that could deliver high-quality translations faster than before. This paper addresses a part of the task: a grammar used for translating from Swedish to English, Finnish, German, and Spanish. The translation system parses Swedish sentences (i.e. templates) and generates translations in other languages, by using th...

Abstract. The paper introduces GF, Grammatical Framework, as a tool for implementing controlled languages. GF provides a high-level grammar formalism and a resource grammar library that make it easy to write grammars that cover similar fragments in several natural languages at the same time. Authoring help tools and automatic translation are provided for all grammars. As an example, a grammar of Attempto Controlled English is implemented and then ported to French, German, and Swedish.
