title = {Korp – the corpus infrastructure of Språkbanken},
abstract = {We present Korp, the corpus infrastructure of Språkbanken (the Swedish Language Bank). The infrastructure consists of three main components: the Korp corpus pipeline, the Korp backend, and the Korp frontend. The Korp corpus pipeline is used for importing corpora, annotating them, and then exporting the annotated corpora into different formats. An essential feature of the pipeline is the ability to leave existing annotations untouched, both structural and word level annotations, and to use the existing annotations as the foundation of other annotations. The Korp backend consists of a set of REST-based web services for searching in and retrieving information about the corpora. Finally, the Korp frontend is a graphical search interface that interacts with the Korp backend. The interface has been inspired by corpus search interfaces such as SketchEngine, Glossa, and DeepDict, and it uses State Chart XML (SCXML) in order to enable users to bookmark interaction states. We give a functional and technical overview of the three components, followed by a discussion of planned future work.

title = {The open lexical infrastructure of Språkbanken},
abstract = {We present our ongoing work on Karp, Språkbanken’s (the Swedish Language Bank) open lexical infrastructure, which has two main functions: (1) to support the work on creating, curating, and integrating our various lexical resources; and (2) to publish daily versions of the resources, making them searchable and downloadable. An important requirement on the lexical infrastructure is also that we maintain a strong bidirectional connection to our corpus infrastructure. At the heart of the infrastructure is the SweFN++ project with the goal to create free Swedish lexical resources geared towards language technology applications. The infrastructure currently hosts 15 Swedish lexical resources, including historical ones, some of which have been created from scratch using existing free resources, both external and in-house. The resources are integrated through links to a pivot lexical resource, SALDO, a large morphological and lexical-semantic resource for modern Swedish. SALDO has been selected as the pivot partly because of its size and quality, but also because its form and sense units have been assigned persistent identifiers (PIDs) to which the lexical information in other lexical resources and in corpora are linked.},

abstract = {Kolorektal cancer (KRC) är den tredje största cancerdiagnosen i Sverige med drygt 5500 drabbade årligen. Primär behandling är kirurgi kompletterad av pre- och postoperativ onkologisk behandling. Standardiserade koncept för accelererat vårdförlopp med kortare vårdtider lägger mycket fokus på fysisk rehabilitering, men mindre på den psykiska påfrestning det innebär att bli opererad för en cancerdiagnos. Patienter förväntas ta stort ansvar för sin rehabilitering, både på sjukhuset och hemma. För att vara förberedd behövs både skriftlig och muntlig information.
Syftet med studien var att kartlägga och karaktärisera det skriftliga informations- och utbildningsmaterial (IOU) som används till patienter som opereras elektivt för KRC. Vidare var syftet att beskriva patienters uppfattning om struktur och innehåll på IOU.
IOU från 28 kliniker som opererar patienter med KRC samlades in (totalt 220 st). För att kunna ge ett mått på texternas svårighetsgrad gjordes språkteknologisk analys på samtliga IOU, där bl.a. ordlängd, meningsbyggnad och jämförelse med annan typ av litteratur mättes På 117 st gjordes en suitabilityanalys med instrumentet SAM+CAM där domän som innehåll, läsbarhet, bilder, layout samt stimulans och motivation för lärande bedömdes. Fem fokusgrupper med patienter genomfördes där patienterna uppmanades att berätta om vad de tycker utmärker ett bra respektive dåligt IOU, vad de saknar i innehåll och när och på vilket sätt de vill ha materialet utlämnat.
Resultatet av språkteknologiska- och suitabilityanalysen visar att de flesta IOU bedömdes som ”adequate”, men spridningen var stor. Patienterna hade önskemål om mer nivåuppdelat/nivåriktat material, där man själv kan välja hur mycket information man vill ha vid ett visst tillfälle. Flera ämnen saknades, eller var för otydligt beskrivna för att patienterna skulle känna sig trygga vid hemgång.
Resultatet av de tre analysmetoderna bör kunna användas för att utveckla en ”verktygslåda” för att i framtiden kunna utforma bättre riktat IOU för patientgruppen.

title = {Adding a constructicon to the Swedish resource network of Språkbanken},
abstract = {This paper presents the integrated Swedish resource network of Språkbanken in general, and its latest addition – a constructicon – in particular. The constructicon, which is still in its early stages, is a collection of (partially) schematic multi-word units, constructions, developed as an addition to the Swedish FrameNet (SweFN). SweFN and the constructicon are integrated with other parts of Språkbanken, both lexical resources and corpora, through the lexical resource SALDO. In most respects, the constructicon is modeled on its English counterpart in Berkeley, and, thus, following the FrameNet format. The most striking differencies are the inclusion of so-called collostructional elements and the treatment of semantic roles, which are defined globally instead of locally as in FrameNet. Incorporating subprojects such as developing methods for automatic identification of constructions in authentic text on the one hand, and accounting for constructions problematic for L2 acquisition on the other, the approach is highly cross-disciplinary in nature, combining various theoretical linguistic perspectives on construction grammar with language technology, lexicography, and L2 research.},

We add the frame information to an extract of the Swedish side of the Kotus and JRC-Acquis corpora using an automatic frame labeler and copy it to the Finnish side. We focus on evaluating the results to get an estimation on how often the parallel sentences can be said to
express the same frame. This sheds light to the questions: Are the same situations in the two languages expressed using different frames, i.e. are the frames transferable even in theory? How well can the frame information of running text be transferred from language to another?

title = {Building Corpus-Informed Word Lists for L2 Vocabulary Learning in Nine Languages},
abstract = {Lexical competence constitutes a crucial aspect in L2 learning, since building a rich repository of words is considered indispensable for successful communication. CALL practitioners have experimented with various kinds of computer-mediated glosses to facilitate L2 vocabulary building in the context of incidental vocabulary learning. Intentional learning, on the other hand, is generally underestimated, since it is considered out of fashion and not in line with the communicative L2 learning paradigm. Yet, work is still being done in this area and substantial body of research indicates that the usefulness of incidental vocabulary learning does not exclude the use of dedicated vocabulary study and that by using aids explicitly geared to building vocabularies (such as word lists and word cards) L2 learners exhibit good retention rates and faster learning gains. Intentional vocabulary study should, therefore, have its place in the instructional and learning context. Regardless of the approach, incidental or intentional, the crucial question with respect to vocabulary teaching/learning remains: which and how many words should we teach/learn at different language levels? An attempt to answer the above question was made within the framework of the EU-funded project titled “KELLY” (Keywords for Language Learning for Young and Adults Alike) presented here. The project aimed at building corpus-informed vocabulary lists for L2 learners ranging from A1 to C2 levels for nine languages: Arabic, Chinese, English, Greek, Italian, Norwegian, Polish, Russian and Swedish. },

The aim of the study is to examine whether the vocabulary used in queries posted to a Swedish regional health web site can be assessed in a way that will enable a terminologist or medical data analysts to instantly identify new term candidates and their relations based on significant co-occurrence patterns. We provide an example application in order to illustrate how the visualizations of co-occurrence relationships between medical and general entities occurring in such logs can be visualized, accessed and explored. To enable a visual exploration of the generated co-occurrence graphs, we employ a general purpose social network analysis tool, Visone (http://visone.info), that permits to visualize and analyze various types of graph structures. Our examples show that visual analytics based on co-occurrence analysis provides insights into the use of layman language in relation to established (professional) terminologies, which may help terminologists decide which terms to include in future terminologies. Increased understanding of the used querying language is also of interest in the context of public health web sites. The query results should reflect the intentions of the information seekers, who may express themselves in layman language that differs from the one used on the available web sites provided by medical professionals.},

abstract = {Online health information seeking has become an important part of people's everyday lives. However, studies have shown that many of those have problems forming effective queries. In order to develop better support and tools for assisting people in health-related query formation we have to gain a deeper understanding into their information seeking behaviour in relation to key issues, such as medication and drugs. The present study attempts to understand the semantics of the users' information needs with respect to medication-related information. Search log queries from the Swedish 1177.se health portal were automatically annotated and categorized according to relevant background knowledge sources. Understanding the semantics of information needs can enable optimization and tailoring of (official) health related information presented to the online consumer, provide better terminology support and thematic coding of the queries and in the long run better models of consumers’ information needs.

title = {Initial Experiments of Medication Event Extraction Using Frame Semantics},
abstract = {Semantic annotation of text corpora for mining complex relations and events has gained a considerable growing attention in the medical domain. The goal of this paper is to present a snapshot of ongoing work that aims to develop and apply an appropriate infrastructure for automatic event labelling and extraction in the Swedish medical domain. Annotated text samples, appropriate lexical resources (e.g. term lists and the Swedish Frame-Net++) and hybrid techniques are currently developed in order to alleviate some of the difficulties of the task. As a case study this paper presents a pilot approach based on the application of the theory of frame semantics to automatically identify and extract detailed medication information from medical texts. Medication information is often written in narrative form (e.g. in clinical records) and is therefore difficult to be acquired and used in computerized systems (e.g. decision support). Currently our approach uses a combination of generic entity and terminology taggers, specifically designed medical frames and various frame-related patterns. Future work intends to improve and enhance current results by using more annotated samples, more medically-relevant frames and combination of supervised learning techniques with the regular expression patterns.},

Several aspects of the task are investigated, including the selection of machine learning features, the effect of choice of syntactic parser, and the ability of the system to generalize to new frames and new genres.
In addition, we evaluate two methods to make the role label classifier more robust: cross-frame generalization and cluster-based features.
Although the small amount of training data limits the performance achievable at the moment, we reach promising results. In particular, the classifier that extracts the boundaries of arguments works well for new frames, which suggests that it already at this stage can be useful in a semi-automatic setting.},

title = {Men, Women and Gods: Distant Reading in Literary Collections - Combining Visual Analytics with Language Technology},
abstract = {The volumes of digitized literary collections in various languages increase at a rapid pace and so increases the need to computationally support the analysis of such data. Literature can be studied in a number of different ways and from many different perspectives and text analysis make up a central component of literature studies. If such analysis can be integrated with advanced visual methods and fed back to the daily work of the literature researcher, then it is likely to reveal the presence of useful and nuanced insights into the complex daily lives, ideas and beliefs of the main characters found in many of the literary works. In this paper we describe the combination of robust text analysis with visual analytics and bring a new set of tools to literary analysis. As a show case, we analyzed a small subset (13 novels of a single author) taken from a large literary collection, the Swedish Literature Bank <http://litteraturbanken.se/#!om/inenglish>. The analysis is based upon two levels of inquiry, namely by focusing on mentions of theistic beings (e.g. Gods' names) as well as mentions of persons' names, including their gender and their normalized, linked variant forms, and examining their appearance in sentences, paragraphs and chapters. The case study shows several successful applications of visual analytics methods to various literature problems and demonstrates the advantages of the implementation of visual literature fingerprinting. Our work is inspired by the notion of distant reading or macronalysis for the analyses of literature collections. We start by recognizing all characters in the novels using a mature language technology (named entity recognition) which can be turned into a tool in aid of text analysis in this field. We apply context cues, lists of animacy and gender markers and inspired by the document centered approach and the labelled consistency principle which is a form of on-line learning from documents under processing which looks at unambiguous usages of words or names for assigning annotations in ambiguous words or names. For instance, if in an unambiguous context where there is a strong gender indicator, such as 'Mrs Alexander' the name 'Alexander' is assigned a feminine gender, then subsequent mentions of the same name in the same discourse will be assigned the feminine gender as well unless there is a conflict with another person with the same name. We argue, that the integration of text analysis such as the one briefly outlined and visualization techniques, such as higher resolution pixel-based fingerprinting, could be put to effective use also in literature studies. We also see an opportunity to devise new ways of exploring the large volumes of literary texts being made available through national cultural heritage digitization projects, for instance by exploring the possibility to show several literary texts (novels) at once. We will illustrate some of the applied techniques using several examples from our case study, such as summary plots based on all the characters in these novels as well as fingerprints based on the distribution of characters across the novels.},

abstract = {Biomedical text mining applications are largely dependent on high quality knowledge resources. Traditionally, these include lexical databases, terminologies, nomenclatures and ontologies and, during the last decade, also corpora of various sizes, variety and diversity. Some of these corpora are annotated with an expanding range of information types and metadata while others become available with a minimal set of annotations. At the same time, it is of great importance that biomedical corpora for lesser-spoken languages also get developed in order to support and facilitate the implementation of practical applications for such languages and to stimulate the development of language technology research and innovation infrastructures in the domain. This paper provides a detailed description of a Swedish biomedical corpus based on the electronic editions of the Journal of the Swedish Medical Association "Läkartidningen" of the years 1996-2010. The corpus consists of a variety of documents that can be related to different medical domains, developed as a response to the increasing needs for large and reliable medical information for Swedish biomedical NLP. The corpus has been structurally annotated with a minimal set of meta information and automatically indexed with the largest and systematically organised computer processable collection of medical terminology, the Swedish SNOMED CT (Systematized Nomenclature of Medicine -- Clinical Terms). This way topic-focused subcorpora, e.g. with diabetes-related content, can be easily developed.},

title = {Contextualisation of functional symptoms in primary health care},
abstract = {Background: a number of patients consulting primary health care have physical symptoms that may be labeled “medically unexplained”, i.e. absence of a demonstrable organic etiology. Common functional somatic symptoms (FSS) are irritable bowel, tension headache and chronic fatigue. FSS-patients are generally frustrated with the inability of health care to alleviate their illness. Health care staff often also feel frustration. The communication between patient and care giver is the key for coming to terms with the problem. Objective: to investigate how complex, vague and long-standing symptoms with no identified organic cause are put into context, interpreted and acted upon in primary health-care interactions. Two types of interventions are envisaged (i) methods for early identification of patients at risk of entering a vicious circle of functional symptoms and (ii) methods for re-interpreting symptoms in alternative and more purposeful ways. Methods: the project studies interactions between patients and nurses giving advice over telephone, consultations between patients and physicians, interviews and study patients' medical case notes. Eligible patients (18-65 y.o.) contact their primary health care centre by telephone, have had at least eight physical consultations with nurses or physicians in the last 12 months and if a majority of the symptoms within this time span had no clear organic or psychiatric cause. The project contains a number of subprojects, according to the type of data collected. Several methods of analysis will be used, mainly critical discourse analysis, phenomenologic-hermeneutic and computation linguistic analyses. (Expected) Results: using the collected data, we describe characteristics of the communication that takes place in these settings and the way symptoms and diseases are represented. This will facilitate the development of future interventions aimed at decreasing the morbidity due to FSS and give further insights into the problem.

define a filter that for each source word selects a small set of target lexical entries, from which
the best match is then selected using generalized edit distance, where edit operations can be
assigned an arbitrary weight. The filter combines a specialized hash function with best-first
search. Our work extends and improves upon a previously proposed hash-based filter, developed
for matching with uniform-weight edit distance. We evaluate an approximate matching system
implemented with the new best-first filter, by conducting several experiments on a historical
corpus and a set of weighted rules taken from the literature. We present running times and
discuss how performance varies using different stopping criteria and target lexica. The results
show that the filter is suitable for large rule sets and million word corpora, and encourage
further development.

@techreport{wilhelmsson-2012-adverbialkarakteristik-160440,
title = {Adverbialkarakteristik för praktisk informationsextraktion i svensk text - Projektrapport},
abstract = {Den aktuella rapporten beskriver ett projekt som i första hand har inneburit ett praktiskt arbete syftande till att skapa en automatiserad process som returnerar frågeled, t.ex. varifrån, för adverbialled, t.ex. inifrån rummet, i svensk digital text. Det är en utbytesprocess som behövs av rent praktiska skäl i uppgiften frågegenerering, vilken innebär att en samling frågor som en text besvarar genereras snabbt automatiskt. Denna process finner sin plats i program som på olika sätt syftar till att ge informationsåtkomst i godtycklig okänd svensk text. Det är i detta tillämpningsfall fråga om att på något sätt öppna upp för den stora informationsmängd som i datalogiskt perspektiv ligger ’ostrukturerad’, dvs. i naturligt språk-form.
Syftet med att avgöra lämpliga frågeled (ofta till en hv-form) för förekommande satsled i text har dock förmodligen en mer allmän relevans än användning i nämnda programtyp. Förutom att också behövas i andra liknande datalingvistiska applikationer kan själva frågeställningen rymmas inom ramarna för grundforskningen. De vanliga semantiskt grundade adverbialkategorierna (vilka skiljer sig åt mellan olika grammatikor) definierar gärna adverbialkategorier just genom att beskriva vilka slags frågor de besvarar. Att som här sikta på att avgöra frågeled för adverbial är en mer detaljerad uppgift än att avgöra adverbialkategori.
Den praktiska metod som implementerats i projektet kan sönderdelas i ett antal steg som antas vara allmängiltiga och svåra att undgå med det aktuella syftet. Indata till programmet är ett i princip godtyckligt adverbialled som användaren i prototypprogrammet kan skriva in. De nämnda steg som tar vid är de följande. 1) En uppmärkning med ordklass- och annan grammatisk information för varje löpord inleder. Detta sker med en statistisk trigrambaserad s.k. Hidden Markov-modell. 2/3) Ett avgörande av vilken strukturtyp som ledet har (bisats, PP, etc.) görs utifrån löporden med informationen i föregående steg. Intimt förknippat med denna uppgift är bestämning av huvudord, och för flera led även bestämning av andra signifikanta komponenter som rektionshuvudord. Lösningen till detta delsteg heter rangbaserad chunkning. 4) De steg som följer härefter skiljer sig mycket åt beroende på den aktuella strukturtypen. För prepositionsfraser undersöks t.ex. preposition och, beroende på vilken preposition det är fråga om, rektionshuvudord, dess grundform och andra ingående textsegment. I arbetet har t.ex. SweFN (Borin, Dannélls, Forsberg, Toporowska Gronostaj, & Kokkinakis, 2010) delvis undersökts för att eventuellt förbättra avgörandet av substantivsemantik, vilket ofta blir relevant för PP-adverbial.
Rapporten visar hur uppgiften praktiskt sett varierar mycket i svårighetsgrad, från de fall där adverbialet utgörs av t.ex. particip-, adverbfraser eller bisatser, då en mappning till motsvarande frågeled ofta kan ske direkt utifrån huvudordet – till de mest komplicerade fallen av PP och s.k. som-fraser där kombinationer av huvudord, rektionshuvudord, dess grundform samt annan syntaktisk och semantisk information krävs för att urskilja förekomsters särskilda frågemotsvarigheter. Ett återkommande tema i det praktiska arbetet är undantag som behöver kännas igen. Exempelvis kategorin satsadverbial, som kan anta många olika strukturella former men som ändå oftast renderar resultatet ’ingen frågemotsvarighet’, måste kännas igen uttryckligen (ev. tillsammans med andra med samma frågeledsresultat). Även processen som helhet bygger emellertid programmeringstekniskt på grundfall och undantag. I många fall, som t.ex. för i-PP finns det en mängd olika motsvarigheter och vad som får utgöra grundfall i programmet blir en empirisk/heuristisk fråga under det att regler skrivs mot faktiska förekomster av adverbial i Stockholm Umeå Corpus (Hädanefter SUC). Att i liksom andra prepositioner kan sägas ha en prototypisk riktningsbetydelse betyder inte att var nödvändigtvis ska fungera som utgångsfall. Det förekommer ’lager’ av undantag inom olika strukturslag i programmet men även externt motiverade sådana utgående från huvudverbet, som genom valensmatchning kan klargöra att ett adverbial är ’prepositionsobjekt’ och därmed får andra omfrågningsegenskaper. De användargränssnitt som skapats och använts för regelskrivande utifrån faktiska exempel har tillåtit viss omedelbar regeluppdatering och återkontroll vid åsynen av felaktiga resultat. Det är också genom tillägg av nya undantagsregler i någon mening som programmet rimligen ska kunna förbättras framöver från den aktuella kvalitetsnivån. Korrektheten som uppnåtts hittills är inte kvantitativt övertygande men detta arbete som saknar föregångare möjliggör kontinuerlig förbättring genom programmet.

A good model for discourse structure analysis needs to account both for local dependencies at the token-level and for global dependencies and statistics. We present techniques on using inter-sentential or sentence-level (global), data-driven, non-grammatical features in the task of parsing
discourse. The parser model follows up previous approach based on using token-level (local) features with conditional random fields for shallow discourse parsing, which is lacking in structural knowledge
of discourse. The parser adopts a two-stage approach where first the local constraints are applied and then global constraints are used on a reduced weighted search space (n-best). In the latter stage we experiment with different rerankers
trained on the first stage n-best parses, which are generated using lexico-syntactic local features. The two-stage parser yields significant improvements over the best performing model of discourse parser on the PDTB corpus.},

Furthermore, the user can instruct OperaVOX™ to automatically and confidentially send these data via email to their speech therapist, voice coach or researcher team. OperaVOX™ makes it easy for everyone to accurately measure changes in the quality of their voice every hour, day, or week and without having to travel to the hospital. Two versions of OperaVOX™ will soon be available on the Apple App Store, one for the general public and another for professionals such as speech and language therapists. We have also worked with world-leading University research teams both in the UK and North America to develop bespoke versions of OperaVOX™ specifically tailored for their research and clinical requirements.},

title = {Calculating the reliability of likelihood ratios: Addressing modelling problems related to small n and tails},
abstract = {In forensic speech science we are often faced with the problem of having a relatively small amount of data which is also
multivariate and distributionally complex. This results in a serious problem exactly in the scenario where potentially large
strengths of evidence could be obtained, i.e., when the trace data are on a tail of the distribution which models either the
prosecution or defence hypothesis and a large magnitude log likelihood ratio is calculated. By definition the sampling of
a distribution is sparse on its tails and this problem is compounded if the model is trained on a small amount of data – small
fluctuations in the training data can lead to large changes in the calculated likelihoods on the tails and thus large changes
in the calculated likelihood ratios for trace data on the tails. Large-magnitude calculated log likelihood ratios are therefore
inherently unreliable.},
