Conference Paper

This study describes the ongoing development of the finite-state description for an endangered minority language, Komi-Zyrian. This work is located in the context where large written and spoken language corpora are available, which creates a set of unique challenges that have to be, and can be, addressed. We describe how we have designed the transd...
Chapter
This is the Festschrift of Dr. Jack Rueter. The book presents peer-reviewed scientific work from Dr. Rueter’s colleagues related to the latest advances in natural language processing, digital resources and endangered languages in a variety of languages such as historical English, Chukchi, Mansi, Erzya, Komi, Finnish, Apurina, Sign Languages, Sami l...

The article presents a rule-based machine translation system from Northern Sami to Norwegian. The grammatical analysis is done with Giellatekno and Divvun's North Sami program for analysis and translation. We have written the transfer component (transfer lexicon and grammatical rules) within the framework of the open machine translation system Aper...

In this episode, we talk about Wikipedia. Is this something that researchers should engage themselves in? What is the greater good? How do you resolve conflicts over facts? And does your research credentials matter for the Wikipedia-community? In 2011 the Guardian wrote an article on this: Wikipedia wants more contributions from academics. Our gues...

Presentasjon frå Wikipedia-akademiet 2015 Wikipedia finst for 287 språk, og på same måte som språka sjølv, varierer storleiken på dei ulikeWikipediaversjonane. Storleiken på språksamfunnet er likevel berre ein av fleire faktorar som harinnverknad på kor vellukka Wikipedia kan bli. Tema her er 6 mellomstore Wikipedia-versjonar (70000-400000 artiklar...

Full-text available
This paper describes the ongoing process of creating a computational morphological model of Plains Cree, a language native to North America, making use of finite-state machines, and with a focus on verbs. We cover prior linguistic theoretical and descriptive models of Plains Cree, moving on to the computational implementation of (chiefly) inflectio...

Full-text available
In this introduction we have tried to present concisely the history of language technology for Uralic languages up until today, and a bit of a desiderata from the point of view of why we organised this special issue. It is of course not possible to cover everything that has happened in a short introduction like this. We have attempted to cover the...
Article
Full-text available
The paper describes a rule-based machine translation (MT) system from North to South Saami. The system is designed for a workflow where North Saami functions as pivot language in translation from Norwegian or Swedish. We envisage manual translation from Norwegian or Swedish to North Saami, and thereafter MT to South Saami. The system was aimed at a...
Article
Full-text available
In recent years, there has been a focus upon open access to research articles, and to access to the data underlying the analyses. The story of the fictious Zigglebottom Tagger stresses the importance of the ability to reproduce results, and the talk will discuss how this goal can be achieved.
Conference Paper
Full-text available
This paper presents aspects of a computational model of the morphology of Plains Cree based on the technology of finite state transducers (FST). The paper focuses in particular on the modeling of nominal morphology. Plains Cree is a polysynthetic language whose nominal morphology relies on prefixes, suffixes and circumfixes. The model of Plains Cre...
Conference Paper
Full-text available
This paper presents an ICALL system for learning complex inflection systems, based upon finite state transducers (FST). Using a FST has several advantages: it makes it possible to generate a virtually unlimited set of exercises with a relatively small amount of work, and it makes it possible to process both input and output according to a wide rang...
Article
This article presents a novel way of combining finite-state transducers (FSTs) with electronic dictionaries, thereby creating efficient reading comprehension dictionaries. We compare a North Saami - Norwegian and a South Saami - Norwegian dictionary, both enriched with an FST, with existing, available dictionaries containing pre-generated paradigms...

!--[if gte mso 9]> <!--[if gte mso 9]> The freedom of choosing what language to use in various contexts is restricted by a wide range of non-linguistic factors. One often-overlooked factor is the availability of a digital infrastructure for the languages in question. To put it bluntly: With no keyboard layout available there also will be no texts w...
Conference Paper
Full-text available
The goal of this article was to show that even a small constraint grammar may achieve results good enough to be used as a lemmatiser. The result shows that a rule set of 115 CG rules is efficient enough to give a lemmatisation accuracy (lemma + POS identification) of 1.056 for open POS.
Conference Paper
Full-text available
Grammatical approaches to language technology are often considered less optimal than statistical approaches in multilingual settings, where large-scale portability becomes an important issue. The present paper argues that there is a notable gain in reusing grammatical resources when porting technology to new languages. The pivot language is North S...

This paper describes the development of two prototype systems for machine trans- lation between North Sámi and Lule Sámi. Experiments were conducted in rule-based machine translation (RBMT), using the Apertium platform, and statistical ma- chine translation (SMT) using the Moses- decoder. The experiments show that both approaches have their advanta...

Full-text available
The article presents Vuosttáš Digisánit (VD), an electronic dictionary from North Sámi to Norwegian. Its novelty lies in the way we have utilized existing resources (a basic dictionary and a morphological analyser/generator) in order to create a reception dictionary for language learners for a morphologically rich language. With only 7,9 % of the w...

Article
Full-text available
The article gives an analysis of the demographic material for North Sa´mi in Norway during the last 150 years, and compares it to key tendencies in some of the Uralic languages of the Soviet Union. The present linguistic landscape can be predicted with great accuracy from Friis’ survey of 1860. At that time, bilingualism among the Norwegians was wi...

Reduplication, the remaining problem in computational morphology is a morpholog- ical process that involves copying the base form wholly or partially. Reduplication can also be classified as either bounded or un- bounded reduplication. Some solutions have been proposed for bounded reduplication. Some of the proposed solutions use ordered replace ru...

This paper describes an annotation system for Sámi language corpora, which consists of structured, running texts. The annotation of the texts is fully automatic, starting from the original documents in different formats. The texts are first extracted from the original documents preserving the original structural markup. The markup is enhanced by a...
Article
This article presents a set of gender assignment rules for Old Norse, which generates gender for the nouns found in Fritzner's Ordbog over Det gamle norske Sprog (Fritzner, 1973). The rule set covers approximately 22 500 of the 26 900 nouns in this dictionary, or 81%. If final -r is taken as a sufficient criterion for masculine (i.e. if we do not a...

14.1 Introduction Koskenniemi's two-level morphology was the first practical general model in the history of computational linguistics for the analysis of morphologically complex languages. In this article we will reconsider one of the key innovations in Koskenniemi (1983), namely the treatment of consonant gra-dation in finite state transducers. W...

Article
The article consists of a principled discussion of how parallel corpora can be used when working with grammatical documentation and lexicographic and terminological language planning for minority languages. An important point is that explicit tools are needed to transfer results achieved in majority language research over to other languages which g...

Artikkelen kvilar på to aksiom: Genustilordning i norsk er regelstyrt, ikkje tilfeldig, og maskulinum er default genus i norsk (norske substantiv er maskuline viss ingenting tilseier noko anna). Ut i frå desse aksioma blir det presentert eit sett av semantiske, morfologiske og fonologiske reglar som gir korrekt genus for ca. 94 % av substantiva i n...
