title = {Transformer-based Swedish Semantic Role Labeling through Transfer Learning},
abstract = {Semantic Role Labeling (SRL) is a task in natural language understanding where the goal is to extract semantic roles for a given sentence. English SRL has achieved state-of-the-art performance using Transformer techniques and supervised learning. However, this technique is not a viable choice for smaller languages like Swedish due to the limited amount of training data. In this paper, we present the first effort in building a Transformer-based SRL system for Swedish by exploring multilingual and cross-lingual transfer learning methods and leveraging the Swedish FrameNet resource. We demonstrate that multilingual transfer learning outperforms two different cross-lingual transfer models. We also found some differences between frames in FrameNet that can either hinder or enhance the model’s performance. The resulting end-to-end model is freely available and will be made accessible through Språkbanken Text’s research infrastructure.},

abstract = {Many collections of digitized newspapers suffer from poor OCR quality, which impacts readability, information retrieval, and analysis of the material. Errors in OCR output can be reduced by applying machine translation models to translate it into a corrected version. Although transformer models show promising results in post-OCR correction and related tasks in other languages, they have not yet been explored for correcting OCR errors in Swedish texts. This paper presents a post-OCR correction model for Swedish 19th to 21th century newspapers based on the pre-trained transformer model ByT5. Three versions of the model were trained on different mixes of training data. The best model, which achieved a 36\% reduction in CER, is made freely available and will be integrated into the automatic processing pipeline of Språkbanken Text, a Swedish language technology infrastructure containing modern and historical written data.},

OCR errors: detection and corrections. For the first task, supervised machine learning methods have shown state-of-the-art performances. Previously proposed approaches have focused
most prominently on combining lexical, contextual and statistical features for detecting errors. In this study, we report a novel system to error detection which is based merely on the n-gram counts of a candidate token. In addition to being simple and computationally less expensive, our proposed system beats previous systems reported in the ICDAR2019 competition on OCR-error detection with notable margins. We achieved state-of-the-art F1-scores for eight out of the ten involved European languages. The maximum improvement is for Spanish which improved from 0.69 to 0.90, and the minimum for Polish from 0.82 to 0.84. },

It has been exploited in a range of natural language processing applications and has inspired the development of framenets for many languages. We present a methodological approach to the extraction and generation of a computational multilingual FrameNet-based grammar and lexicon. The approach leverages FrameNet-annotated corpora to automatically extract a set of cross-lingual semantico-syntactic valence patterns. Based on data from Berkeley FrameNet and Swedish FrameNet, the proposed approach has been implemented in Grammatical Framework (GF), a categorial grammar formalism specialized for multilingual grammars. The implementation of the grammar and lexicon is supported by the design of FrameNet, providing a frame semantic abstraction layer, an interlingual semantic application programming interface (API), over the interlingual syntactic API already provided by GF Resource Grammar Library. The evaluation of the acquired grammar and lexicon shows the feasibility of the approach. Additionally, we illustrate how the FrameNet-based grammar and lexicon are exploited in two distinct multilingual controlled natural language applications.

This raises the question: Do we always need many features to achieve better results? This is an open-ended question and its answer might depend on the task at hand. For OCR error detection, we experimented and found that interestingly a uni-feature based system conquered multi-feature based systems on a Swedish data set achieving state-of-the art results, and performed equally well on an English dataset. We also experimented to find which machine learning algorithm is more suitable for the task at hand by comparing the performance of five well-known machine learning algorithms, namely Logistic regression, Decision Trees, Bernoulli Naive Bayes, Naive Bays, and Support Vector Machines. },

abstract = {Great expectations are placed on the capacity of heritage institutions to make their collections available in digital format. Datadriven research is becoming a key concept within the humanities and social sciences. Kungliga biblioteket’s (National Library of Sweden, KB)collections of digitised newspaper can thus be regarded as unique cultural data sets with information that rarely is conveyed in other media types. The digital format makes it possible to explore these resources in ways not feasible while in printed form. As texts are no longer only read but also subjected to computer based analysis the demand on the correct rendering of the original text increases. OCR technologies for converting images to machine-readable text play a fundamental part in making these resources available, but the effectiveness vary with the type of document being processed. This is evident in relation to the digitisation of newspapers where factors relating to their production, layout and paper quality often impair the OCR production. In order to improve the machine readable text, especially in relation to the digitisation of newspapers, KB initiated the development of an OCR-module where key parameters can be adjusted according to the characteristics of the material being processed. The purpose of this paper is to present the project goals and methods.},

them are taken. These directions often need to be revised when not beforehand foreseen problems arise. One assumption that was made already in the early development stages of SweFN was that each lexical entry from the reference lexicon, SALDO, would evoke only one semantic frame in SweFN. If a lexical entry evoked more than one frame, it entailed more than one sense and therefore required a new entry in the lexicon.
As work progressed, this inclination towards splitting, in the perpetual lumpers and splitters discussion proved to be progressively untenable. This paper will give an account of the problems which were encountered and suggestions for solutions on polysemy issues forcing a discussion on lumping or splitting.},

abstract = {Cultural heritage appears to be a very useful use case for Semantic Web technologies. The domain provides with plenty of circumstances where linkages between different knowledge sources are required to ensure access to rich information and respond to the needs of professionals dealing with cultural heritage content. Semantic Web technologies offer the technological backbone to meet the requirement of integrating heterogeneous data easily, but they are still more adapted to be consumed by computers than by humans, especially non-engineers or developers. This chapter is about a technique which allows interaction in natural language with semantic knowledge bases. The proposed technique offers a method that allows querying a semantic repository in natural language and obtaining results from it as a coherent text. This unique solution includes several steps of transition from natural language to SPARQL and from RDF to coherent multilingual descriptions, using the Grammatical Framework, GF. The approach builds on a semantic knowledge infrastructure in RDF, it is based on OWLIM-SE and the data integration method Reason-able View supplied with an ontological reference layer. The latter is connected via formal rules with abstract representations derived from the syntactic trees of natural language input using the GF resource grammar library.

abstract = {One of the first issues that a programmer must tackle when writing a complete computer program that processes natural language is
how to design the morphological component. A typical morphological component should cover three main aspects in a given language:
(1) the lexicon, i.e. how morphemes are encoded, (2) orthographic changes, and (3) morphotactic variations. This is in particular
challenging when dealing with Semitic languages because of their non-concatenative morphology called root-and pattern morphology.
In this paper we describe the design of two morphological components for Hebrew and Maltese verbs in the context of the Grammatical
Framework (GF). The components are implemented as a part of larger grammars and are currently under development. We found that
although Hebrew and Maltese share some common characteristics in their morphology, it seems difficult to generalize morphosyntactic
rules across Semitic verbs when the focus is towards computational linguistics motivated lexicons. We describe and compare the verb
morphology of Hebrew and Maltese and motivate our implementation efforts towards a complete open source type theoretical resource
grammars for Semitic languages. Future work will focus on semantic aspects of morphological processing.},

abstract = {During the last decade, there has been a shift from developing natural language systems to developing generic systems that are capable of producing natural language descriptions directly from Web ontologies. To make these descriptions coherent and accessible in different languages, a methodology is needed for identifying the general principles that would determine the distribution of referential forms. Previous work has proved through crosslinguistic investigations that strategies for building co-reference are language dependent. However, to our knowledge, there is no language generation methodology that makes a distinction between languages about the generation of referential chains. To determine the principles governing referential chains, we gathered data from three languages: English, Swedish and Hebrew, and studied how co-reference is expressed in a discourse. As a result of the study, a set of language specific co-reference strategies were identified. Using these strategies, an ontology based multilingual grammar for generating written natural language descriptions about paintings was implemented in the Grammatical Framework. A preliminary evaluation of our method shows language-dependent coreference strategies lead to better generation results. },

We investigate how chains of referential expressions are realized in English, Swedish and Hebrew, and suggest several coreference strategies that can be used to generate coherent descriptions about paintings. The suggested strategies focus on the need to produce paragraph-sized written natural language descriptions from formal structured representations presented in the Semantic Web. We account for principles of coreference by introducing a new modularized approach to automatically generate chains of referential expressions from ontologies. We demonstrate the feasibility of the approach by implementing a system where a Semantic Web domain ontology serves as the background knowledge representation and where
the language-specific coreference strategies are incorporated. The system uses both the principles of discourse structures and coreference strategies to guide the generation process. We show how the system successfully generates coherent, well-formed descriptions in multiple languages.},

Supervised machine learning was applied to monitor the performance of the rule-based method, using Memory Based Learning (MBL). The rule-based algorithm was evaluated on a hand tagged acronym corpus and performance was measured using standard measures recall, precision and f-score.
The results show that performance
could further improve by increasing the training set and modifying the input settings for the machine learning algorithms. An analysis of the errors produced indicates that further improvement of the rule-based method requires the use of syntactic information and textual pre-processing.},

title = {Thinking Green: Toward Swedish FrameNet++},
abstract = {Access to multi-layered lexical, grammatical and semantic information representing
text content is a prerequisite for efficient automatic understanding
and generation of natural language. A FrameNet is considered a valuable
resource for both linguistics and language technology research that
may contribute to the achievement of these goals.
Currently, FrameNet-like resources exist for a few languages,1 including
some domain-specific and multilingual initiatives (Dolbey et al., 2006;
Boas, 2009; Uematsu et al., 2009; Venturi et al., 2009), but are unavailable
for most languages, including Swedish, although there have been some
pilot studies exploring the semi-automatic acquisition of Swedish frames
(Johansson & Nugues, 2006; Borin et al., 2007).
At the University of Gothenburg, we are now embarking on a project to
build a Swedish FrameNet-like resource. A novel feature of this project is
that the Swedish FrameNetwill be an integral part of a largermany-faceted
lexical resource. Hence the name Swedish FrameNet++ (SweFN++).

title = {The Value of Weights in Automatically Generated Text Structures},
abstract = {One question that arises if we want to evolve generation techniques
to accommodate Web ontologies is how to capture and expose the
relevant ontology content to the user. This paper presents an attempt
to answer the question about how to select the ontology statements that
are significant for the user and present those statements in a way that
helps the user to learn. Our generation approach combines bottom-up
and top-down techniques with enhanced comparison methods to tailor
descriptions about a concept described in an ontology. A preliminary
evaluation indicates that the process of computing preferable property
weights in addition to enhanced generation methods has a positive effect
on the text structure and its content. Future work aims to assign
grammar rules and lexical entries in order to produce coherent texts that
follow on from the generated text structures in several languages.},

(CRM) ISO standard for conceptual models of museums. The rationale of this work is to increase users’ knowledge and interest in
the cultural heritage domain by allowing the user to select his preferable syntax presentation and influence the order of the generated
information using generation techniques and Semantic Web technologies. We chose for study a small amount of logical relations represented
in the ontology and wrote a grammar that is capable to describe them in natural language through user editing. We present the
multilingual source authoring environment, which is built upon the grammatical framework (GF) formalism and show how it is utilized
to generate multiple texts from the CRM domain ontology. The initial results comprise texts, which vary in syntax and content.},

prototype multilingual generator that presents simulated breast cancer Electronic Health Records (EHRs) in English to French and Swedish. The purpose of this work was to test how much effort
it would require to modify this limited-domain, template-based English generator to enable it to generate in French and Swedish. We describe the
adaptation to both languages, viewing the grammatical aspects involved and explaining the modifications performed. This work illustrates how the same
underlying knowledge representation can be used to generate output texts in multiple languages with only minor linguistic modifications.},

title = {Recognizing Acronyms and their Definitions in Swedish Medical Texts},
abstract = {This paper addresses the task of recognizing acronym-definition pairs in Swedish (medical) texts as well as the compilation of a freely
available sample of such manually annotated pairs. A material suitable not only for supervised learning experiments, but also as
a testbed for the evaluation of the quality of future acronym-definition recognition systems. There are a number of approaches to
the identification described in the literature, particularly within the biomedical domain, but none of those addresses the variation and
complexity exhibited in a language other than English. This is realized by the fact that we can have a mixture of two languages in
the same document and/or sentence, i.e. Swedish and English; that Swedish is a compound language that significantly deteriorates
the performance of previous approaches (without adaptations) and, most importantly, the fact that there is a large variation of
possible acronym-definition permutations realized in the analysed corpora, a variation that is usually ignored in previous studies.
