Konferensbidrag (refereegranskat)abstract
- Using the technique of ”semantic mirroring”a graph is obtained that representswords and their translations from a parallelcorpus or a bilingual lexicon. The connectednessof the graph holds informationabout the different meanings of words thatoccur in the translations. Spectral graphtheory is used to partition the graph, whichleads to a grouping of the words accordingto different senses. We also report resultsfrom an evaluation using a small sample ofseed words from a lexicon of Swedish andEnglish adjectives.

A knowledge-lite approach to word alignment
- 2000

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- The most promising approach to word alignment is to combine statistical methods with non-statistical information sources. Some of the proposed non-statistical sources, including bilingual dictionaries, POS-taggers and lemmatizers, rely on considerable linguistic knowledge, while other knowledge-lite sources such as cognate heuristics and word order heuristics can be implemented relatively easy. While knowledge-heavy sources might be expected to give better performance, knowledge-lite systems are easier to port to new language pairs and text types, and they can give sufficiently good results for many purposes, e.g. if the output is to be used by a human user for the creation of a complete word-aligned bitext. In this paper we describe the current status of the Linköping Word Aligner (LWA), which combines the use of statistical measures of co-occurrence with four knowledge-lite modules for (i)) word categorization, (ii) morphological variation, (iii) word order, and (iv) phrase recognition. We demonstrate the portability of the system (from English-Swedish texts to French-English texts) and present results for these two language-pairs. Finally, we will report observations from an error analysis of system output, and identify the major strengths and weaknesses of the system.

A New Gold Standard for Swedish NERC

Konferensbidrag (refereegranskat)abstract
- Starting in 2018 Swe-Clarin members are working cross-instituionally on special themes. In thispaper we report ongoing work in a project aimed at the creation of a new gold standard forSwedish Named-Entity Recognition and Categorisation. In contrast to previous efforts the newresource will contain data from both social media and edited text. The resource will be madefreely available through Spr ̊akbankenText

Alignment-based profiling of Europarl data in an English-Swedish parallel corpus
- 2010
-
Ingår i: Proceedings of the Seventh conference on International Language Resources and Evaluation (LREC'10). - Paris, France : European Language Resources Association (ELRA). ; , s. 3398-3404
-
Konferensbidrag (refereegranskat)abstract
- This paper profiles the Europarl part of an English-Swedish parallel corpus and compares it with three other subcorpora of the sameparallel corpus. We first describe our method for comparison which is based on alignments, both at the token level and the structurallevel. Although two of the other subcorpora contains fiction, it is found that the Europarl part is the one having the highest proportion ofmany types of restructurings, including additions, deletions and long distance reorderings. We explain this by the fact that the majorityof Europarl segments are parallel translations.

Analysing Changes in Official Use of the Design Concept Using SweCLARIN Resources
- 2022
-
Ingår i: Proceedings of the CLARIN Annual meeting.
-
Konferensbidrag (refereegranskat)abstract
- We show how the tools and language resources developed within the SweClarin infrastructure can be used to investigate changes in the use and understanding of the Swedish related words arkitektur, design, form, and formgivning. Specifically, we compare their use in two governmental public reports on design, one from 1999 and the other from 2015. We test the hypothesis that their meaning has developed in a way that blurs distinctions that may be important to stakeholders in the respective fields.

Analysing changes in official use of the design concept using SweCLARIN resources

Ingår i: Selected papers from the CLARIN Annual Conference 2022. - Linköping : Linköping University Electronic Press. - 9789180752541
-
Konferensbidrag (refereegranskat)abstract
- We investigate changes in the use of four Swedish words from the fields of design and archi- tecture. It has been suggested that their meanings have been blurred, especially in governmental reports and policy documents, so that distinctions between them that are important to stakeholders in the respective fields are lost. Specifically, we compare usage in two governmental public reports on design, one from 1999 and the other from 2015, and additionally in opinion responses to the 2015 report. Our approach is to contextualise occurrences of the words in different representations of the texts using word embeddings, topic modelling and sentiment analysis. Tools and language resources developed within the SweClarin infrastructure have been crucial for the implementation of the study.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Since the SweClarin project began in 2015 its resources in terms of data and tools have been used in many different projects including linguistics. A research area where they have been less employed is the study of names. In this paper I suggest that language technology and general corpora can be used to contribute to the sociological study of personal names and offer a few examples. As is fit for the occasioin I take Lars as the point of departure.

Automatic Processing of Parallel Corpora: A Swedish Perspective
- 1999
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- As empirical methods have come to the fore in multilingual language technology and translation studies, the processing of parallel texts and parallel corpora have become a major research area in computational linguistics. In this article we review the state of the art in alignment and data extraction techniques for parallel texts, and give an overview of current work in Sweden in this area. In a final section, we summarize the results achieved so far and make some proposals for future research.
