- We create a gold standard for sentiment annotation of Swedish terms, using the freely available SALDO lexicon and the Gigaword corpus. For this purpose, we employ a multi-stage approach combining corpus-based frequency sampling, direct score annotation and Best-Worst Scaling. In addition to obtaining a gold standard, we analyze the data from our process and we draw conclusions about the optimal sentiment model.

Konferensbidrag (refereegranskat)abstract
- The natural language processing subfield known as sentiment analysis or opinion mining has seen an explosive expansion over the last decade or so, and sentiment analysis has become a standard item in the NLP toolbox. Still, many theoretical and methodological questions remain unanswered and resource gaps unfilled. Most work on automated sentiment analysis has been done on English and a few other languages; for most written languages of the world, this tool is not available. This paper describes the development of an extensive sentiment lexicon for written (standard) Swedish. We investigate different methods for developing a sentiment lexicon for Swedish. We use an existing gold standard dataset for training and testing. For each word sense from the SALDO Swedish lexicon, we assign a real value sentiment score in the range [-1,1] and produce a sentiment label. We implement and evaluate three methods: a graph-based method that iterates over the SALDO structure, a method based on random paths over the SALDO structure and a corpus-driven method based on word embeddings. The resulting sense-disambiguated sentiment lexicon (SenSALDO) is an open source resource and freely available from Språkbanken, The Swedish Language Bank at the University of Gothenburg.

Synchronic and Diachronic Aspects of Kanashi
- 2022
-
Samlingsverk (redaktörskap) (refereegranskat)abstract
- Kanashi, a Sino-Tibetan (ST) language belonging to the West Himalayish (WH) subbranch of this language family, is spoken in one single village (Malana in Kullu district, Himachal Pradesh state, India), which is surrounded by villages where – entirely unrelated – Indo-Aryan (IA) languages are spoken. Until we started working on Kanashi, very little linguistic material was available. Researchers have long speculated about the prehistory of Kanashi: how did it happen that it ended up spoken in one single village, completely cut off from its closest linguistic relatives? Even though suggestions have been made of a close genealogical relation between Kanashi and Kinnauri (another WH language), at present separated by over 200 km of rugged mountainous terrain, their shared linguistic features have not been discussed in the literature.Based on primary fieldwork, this volume presents some synchronic and diachronic aspects of Kanashi. The synchronic description of Kanashi includes a general introduction on Malana and the Kanashi language community (chapter 1), linguistic descriptions of its sound system (chapter 2), of phonological variation in Kanashi (chapter 4), of its grammar (chapter 3) and of its intriguing numeral systems (chapter 5), as well as basic vocabulary lists (Kanashi-English, English-Kanashi) (chapter 9).As for the diachronic and genealogical aspects (chapters 6–8), we compare and contrast Kanashi with other ST languages of this region (in particular languages of Kinnaur, notably Kinnauri), thereby uncovering some intriguing linguistic features common to Kanashi and Kinnauri which provide insights into their common history. For instance: a subset of borrowed IA nouns and adjectives in both languages end in -(a)ŋ or -(a)s, elements which do not otherwise appear in Kanashi or Kinnauri, nor in the IA donor languages (chapter 6); and both languages have a valency changing mechanism where the valency increasing marker -jaː alternates with the intransitive marker -e(d) in borrowed IA verbs (again: elements without an obvious provenance in the donor or recipient language) (chapter 7). These features are neither found in IA languages nor in the WH languages geographically closest to Kanashi (Pattani, Bunan, Tinani), but only in Kinnauri, which is spoken further away. Intriguingly, traces of some of these features are also found in some ST languages belonging to different ST subgroups (both WH and non-WH), spoken in Uttarakhand in India and in western Nepal (e.g. Rongpo, Chaudangsi, Raji and Raute). This raises fundamental questions regarding genealogical classification, language contact and prehistory of the WH group of languages and of this part of the Indian Himalayas, which are also discussed in the volume (chapter 8).

Defining a gold standard for a Swedish sentiment lexicon: Towards higher-yield text mining in the digital humanities
- 2018

Konferensbidrag (refereegranskat)abstract
- There is an increasing demand for multilingual sentiment analysis, and most work on sentiment lexicons is still carried out based on English lexicons like WordNet. In addition, many of the non-English sentiment lexicons that do exist have been compiled by (machine) translation from English resources, thereby arguably obscuring possible language-specific characteristics of sentiment-loaded vocabulary. In this paper we describe the creation from scratch of a gold standard for the sentiment annotation of Swedish terms as a first step towards the creation of a full-fledged sentiment lexicon for Swedish.

A bird’s-eye view on South Asian languages through LSI: Areal or genetic relationships?
- 2021

Tidskriftsartikel (refereegranskat)abstract
- We present initial exploratory work on illuminating the long-standing question of areal versus genealogical connections in South Asia using computational data visualization tools. With respect to genealogy, we focus on the subclassification of Indo-Aryan, the most ubiquitous language family of South Asia. The intent here is methodological: we explore computational methods for visualizing large datasets of linguistic features, in our case 63 features from 200 languages representing four language families of South Asia, coming out of a digitized version of Grierson’s Linguistic Survey of India. To this dataset we apply phylogenetic software originally developed in the context of computational biology for clustering the languages and displaying the clusters in the form of networks. We further explore multiple correspondence analysis as a way of illustrating how linguistic feature bundles correlate with extrinsically defined groupings of languages (genealogical and geographical). Finally, map visualization of combinations of linguistic features and language genealogy is suggested as an aid in distinguishing genealogical and areal features. On the whole, our results are in line with the conclusions of earlier studies: Areality and genealogy are strongly intertwined in South Asia, the traditional lower-level subclassification of Indo-Aryan is largely upheld, and there is a clearly discernible areal east–west divide cutting across language families.

Swedish FrameNet++ and comparative linguistics

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- In this chapter we describe a multilingual extension of Swedish FrameNet++, intended to address research questions of a broad comparative nature, in genealogical, areal and typological linguistics, focusing on the integration into Swedish FrameNet++ of so-called core vocabularies, used in several linguistic subfields in order to conduct massive comparative studies involving large numbers of languages. Specifically, we describe the inclusion of two such lexical databases covering several hundred South Asian languages, with the aim of investigating areal and genealogical connections among these languages.
