    Similarity-Based Alignment of Monolingual Corpora for Text Simplification2016In: CL4LC 2016 - Computational Linguistics for Linguistic Complexity: Proceedings of the Workshop, 2016, p. 154-163Conference paper (Refereed)
    Abstract [en]

    Comparable or parallel corpora are beneficial for many NLP tasks.  The automatic collection of corpora enables large-scale resources, even for less-resourced languages, which in turn can be useful for deducing rules and patterns for text rewriting algorithms, a subtask of automatic text simplification. We present two methods for the alignment of Swedish easy-to-read text segments to text segments from a reference corpus.  The first method (M1) was originally developed for the task of text reuse detection, measuring sentence similarity by a modified version of a TF-IDF vector space model. A second method (M2), also accounting for part-of-speech tags, was devel- oped, and the methods were compared.  For evaluation, a crowdsourcing platform was built for human judgement data collection, and preliminary results showed that cosine similarity relates better to human ranks than the Dice coefficient. We also saw a tendency that including syntactic context to the TF-IDF vector space model is beneficial for this kind of paraphrase alignment task.

    A Method for Iterative Implementation of Dialogue Management2001In: IJCAI Workshop on Knowledge and Reasoning in Practical Dialogue Systems, Seattle, 2001Conference paper (Refereed)
    Abstract [en]

    This paper presents an approach to implementation of dialogue management modules for dialogue systems. The implementation method is divided into two distinct, but correlated, steps; Conceptual design and Framework customisation. Conceptual design and framework customisation are two mutually dependent sides of the same phenomena, where the former is an on-paper activity that results in a design document and the latter results in the actual program code. The method is iterative and conforms with software development methods, such as, extreme programming, scenario-based design and reusable object-oriented software development. In the paper, this is further elaborated and how it relates to dialogue systems development.

    LinTest, A development tool for testing dialogue systems2006In: Proceedings of INTERSPEECH. 2006 VOLS 1-5, Baixas, FRANCE: International Speech Communication Association , 2006, p. 489-492Conference paper (Refereed)
    Abstract [en]

    In this paper we present a development tool for testing dialogue systems. Testing software through the specification is important for software development in general and should be as automated as possible. For dialogue systems, the corpus can be seen as one part of the specification and the dialogue system should be tested on available corpora on each new build. The testing tool is inspired from work on agile software development methods, test driven development and unit testing, and can be used in two modes and during various phases of development.

    Features indicating readability in Swedish text2013In: Proceedings of the 19th Nordic Conference of Computational Linguistics (NODALIDA 2013) / [ed] Stephan Oepen, Kristin Hagen, Janne Bondi Johannesse, Linköping, 2013, p. 27-40Conference paper (Refereed)
    Abstract [en]

    Studies have shown that modern methods of readability assessment, using automated linguistic analysis and machine learning (ML), is a viable road forward for readability classification and ranking. In this paper we present a study of different levels of analysis and a large number of features and how they affect an ML-system’s accuracy when it comes to readability assessment. We test a large number of features proposed for different languages (mainly English) and evaluate their usefulness for readability assessment for Swedish as well as comparing their performance to that of established metrics. We find that the best performing features are language models based on part-of-speech and dependency type.

    Classifying easy-to-read texts without parsing2014In: Proceedings of the 3rd Workshop on Predicting and Improving Text Readability for Target Reader Populations (PITR), Association for Computational Linguistics, 2014, p. 114-122Conference paper (Refereed)
    Abstract [en]

    Document classification using automated linguistic analysis and machine learning (ML) has been shown to be a viable road forward for readability assessment. The best models can be trained to decide if a text is easy to read or not with very high accuracy, e.g. a model using 117 parameters from shallow, lexical, morphological and syntactic analyses achieves 98,9% accuracy. In this paper we compare models created by parameter optimization over subsets of that total model to find out to which extent different high-performing models tend to consist of the same parameters and if it is possible to find models that only use features not requiring parsing. We used a genetic algorithm to systematically optimize parameter sets of fixed sizes using accuracy of a Support Vector Machine classi- fier as fitness function. Our results show that it is possible to find models almost as good as the currently best models while omitting parsing based features.

    Implicit readability ranking using the latent variable of a Bayesian Probit model2016In: CL4LC 2016 - Computational Linguistics for Linguistic Complexity: Proceedings of the Workshop, 2016, p. 104-112Conference paper (Refereed)
    Abstract [en]

    Data driven approaches to readability analysis for languages other than English has been plagued by a scarcity of suitable corpora.  Often, relevant corpora consist only of easy-to-read texts with no  rank  information  or  empirical  readability  scores,  making  only  binary  approaches,  such  as classification, applicable.  We propose a Bayesian, latent variable, approach to get the most out of these kinds of corpora. In this paper we present results on using such a model for readability ranking. The model is evaluated on a preliminary corpus of ranked student texts with encourag- ing results.  We also assess the model by showing that it performs readability classification on par with a state of the art classifier while at the same being transparent enough to allow more sophisticated interpretations.

    An Exploratory Study on Genre Classification using Readability Features2016Conference paper (Other academic)
    Abstract [en]

    We present a preliminary study that explores whether text features used for readability assessment are reliable genre-revealingfeatures. We empirically explore the difference between genre and domain. We carry out two sets of experiments with bothsupervised and unsupervised methods. Findings on the Swedish national corpus (the SUC) show that readability cues are goodindicators of genre variation.

    A multivariate model for classifying texts’ readability2015In: Proceedings of the 20th Nordic Conference of Computational Linguistics / [ed] Beáta Megyesi, 2015, p. 257-261Conference paper (Refereed)
    Abstract [en]

    We report on results from using the multivariate readability model SVIT to classify texts into various levels. We investigate how the language features integrated in the SVIT model can be transformed to values on known criteria like vocabulary, grammatical fluency and propositional knowledge. Such text criteria, sensitive to content, readability and genre in combination with the profile of a student’s reading ability form the base to individually adapted texts. The procedure of levelling texts into different stages of complexity is presented along with results from the first cycle of tests conducted on 8th grade students. The results show that SVIT can be used to classify texts into different complexity levels.

    Studies on automatic assessment of students’ reading ability2014In: Proceedings of the Fifth Swedish Language Technology Conference (SLTC-14), 2014Conference paper (Refereed)
    Abstract [en]

    We report results from ongoing research on developing sophisticated measures for assessing a student’s reading ability and a tool for the student and teacher to create a profile of this ability. In the project we will also investigate how these measures can be transformed to values on known criteria like vocabulary, grammatical fluency and so forth, and how these can be used to analyse texts. Such text criteria, sensitive to content, readability and genre in combination with the profile of a student’s reading ability will form the base to individually adapted texts. Techniques and tools will be developed for selecting suitable texts, automatic summarisation of texts and automatic transformation to easy-to-read Swedish.

    Abstract [en]

    Developing software is a key methodology in cognitive science. Lisp is a family of programming languages that historically has been very influential in cognitive science in general and in the field of artificial intelligence in particular. Scientists and practitioners alike were drawn to Lisp due to its intelligent design and elegance. However, for various reasons it has become more and more uncommon to use Lisp in cognitive science and AI research.

    Clojure is a modern Lisp language that compiles both to the Java virtual machine and to Javascript. This enables us to write fast, stand-alone applications in Lisp that runs on computers, smartphones and in web browsers - everything written in the same language. Clojure encourages functional programming – an approach to software development in where we model our application in terms of data flowing through the system. The design and implementation of an application then become a process where the developer writes modular parts that transforms data. Such workflow open up for very elegant solutions to some of today's problems in software development in general and in the field of web applications in particular.

    Clojure can be used for everything from resource-intensive server-side applications to lightweight applications that runs in the browser or as a smartphone application. In addition, Clojure has a rich eco-system of freely available libraries to make development become like building things with LEGO.

    In this talk, we will give a technical demonstration of the language in where we demonstrate various aspects of the language that is relevant for cognitive science researchers and practitioners. We will also demonstrate an e- Health application that has been written in Clojure. It enables clinical practitioners to use the Internet to provide psychological treatment to individuals with for example depression and anxiety. Our experiences with Clojure in developing this application will be described. We have also made efforts to teach software development with Clojure to clinical psychologists to enable them to write e-Health web applications without any background in software development. This project will also be described in the talk.

    We believe that Clojure combines the best of both worlds – elegance and performance. With this talk, we hope to demonstrate why we believe Clojure is a perfect fit for both research and practice in the field of cognitive science.

    Abstract [en]

    Natural language interfaces require dialogue models that allow for robust, habitable and efficient interaction. This paper presents such a model for dialogue management for natural language interfaces. The model is based on empirical studies of human computer interaction in various simple service applications. It is shown that for applications belonging to this class the dialogue can be handled using fairly simple means. The interaction can be modeled in a dialogue grammar with information on the functional role of an utterance as conveyed in the linguistic structure. Focusing is handled using dialogue objects recorded in a dialogue tree representing the constituents of the dialogue. The dialogue objects in the dialogue tree can be accessed by the various modules for interpretation, generation and background system access. Focused entities are modeled in entities pertaining to objects or sets of objects, and related domain concept information; properties of the domain objects. A simple copying principle, where a new dialogue object's focal parameters are instantiated with information from the preceding dialogue object, accounts for most context dependent utterances. The action to be carried out by the interface is determined on the basis of how the objects and related properties are specified. This in turn depends on information presented in the user utterance, context information from the dialogue tree and information in the domain model. The use of dialogue objects facilitates customization to the sublanguage utilized in a specific application. The framework has successfully been applied to various background systems and interaction modalities. In the paper results from the customization of the dialogue manager to three typed interaction applications are presented together with results from applying the model to two applications utilizing spoken interaction.

    Experiences from combining dialogue system development with information extraction techniques2004In: New Directions in Question Answering / [ed] Mark T. Maybury, Boston: AAAIMIT Press , 2004, p. 153-163Chapter in book (Other academic)
    Abstract [en]

    Next generation question answering systems are challenged on many fronts including but not limited to massive, heterogeneous and sometimes streaming collections, diverse and challenging users, and the need to be sensitive to context, ambiguity, and even deception. This chapter describes new directions in question answering (QA) including enhanced question processing, source selection, document retrieval, answer determination, and answer presentation generation. We consider important directions such as answering questions in context (e.g., previous queries, day or time, the data, the task, location of the interactive device), scenario based QA, event and temporal QA, spatial QA, opinionoid QA, multimodal QA, multilingual QA, user centered and collaborative QA, explanation, interactive QA, QA reuse, and novel architectures for QA. The chapter concludes by outlining a roadmap of the future of question answering, articulating necessary resources for, impediments to, and planned or possible future capabilities.

    Using Language Technology to Improve Interaction and Provide Skim Reading Abilities to Audio Information Services2008In: Collaboration and the Knowledge Economy: Issues, Applications, Case Studies / [ed] Paul Cunningham and Miriam Cunningham, IOS Press, 2008, p. 1289-Conference paper (Other academic)
    Abstract [en]

    In this paper we present language technology enhancements to audio-based information services (i.e. services where information is presented using spoken language). The enhancements presented in the paper addresses two issues for audio-based services: 1) interaction with the service is rigid and 2) the ability to listen to summaries is limited. Our developments allow for more natural and efficient control of the service and means that facilitates skim reading. Using speech dialogue instead of traditional buttons provides means for more advanced navigation in the audio material. Vector space techniques are used to collect the most relevant sentences in a text and allows for skim reading of varying depth.

    Distilling dialogues - A method using natural dialogue corpora for dialogue systems development2000In: Proceedings of 6th Applied Natural Language Processing Conference, Seattle, USA: Association for Computational Linguistics Stroudsburg , 2000, p. 44-51Conference paper (Refereed)
    Abstract [en]

    We report on a method for utilising corpora collected in natural settings. It is based on distilling (re-writing) natural dialogues to elicit the type of dialogue that would occur if one the dialogue participants was a computer instead of a human. The method is a complement to other means such as Wizard of Oz-studies and un-distilled natural dialogues. We present the distilling method and guidelines for distillation. We also illustrate how the method affects a corpus of dialogues and discuss the pros and cons of three approaches in different phases of dialogue systems development.

    T-MASTER -- A tool for assessing students' reading abilities2015In: Proceedings of the 7th International Conference on Computer Supported Education (CSEDU 2015), Lisbon, Portugal, SciTePress, 2015, p. 220-227Conference paper (Refereed)
    Abstract [en]

    We present T-MASTER, a tool for assessing students’ reading skills on a variety of dimensions. T-MASTER uses sophisticated measures for assessing a student’s reading comprehension and vocabulary understanding. Texts are selected based on their difficulty using novel readability measures and tests are created based on the texts. The results are analyzed in T-MASTER, and the numerical results are mapped to textual descriptions that describe the student’s reading abilities on the dimensions being analysed. These results are presented to the teacher in a form that is easily comprehensible, and lends itself to inspection of each individual student’s results.

    Investigations of Synonym Replacement for Swedish2013In: Northern European Journal of Language Technology (NEJLT), ISSN 2000-1533, Vol. 3, no 3, p. 41-59Article in journal (Refereed)
    Abstract [en]

    We present results from an investigation on automatic synonym replacement for Swedish. Three different methods for choosing alternative synonyms were evaluated: (1) based on word frequency, (2) based on word length, and (3) based on level of synonymy. These three strategies were evaluated in terms of standardized readability metrics for Swedish, average word length, proportion of long words, and in relation to the ratio of errors in relation to replacements. The results show an improvement in readability for most strategies, but also show that erroneous substitutions are frequent.

    Automatic handling of Frequently Asked Questions using Latent Semantic Analysis2009In: IJCAI Workshop on Knowledge and Reasoning in Practical Dialogue Systems, Association for the Advancement of Artificial Intelligence , 2009Conference paper (Refereed)
    Abstract [en]

    We present results from using Latent Semantic Analysis (LSA) for automatic handling of FAQs (Frequently Asked Questions). FAQs have a high language variability and include a mixture of technical and non-technical terms. LSA has a potential to be useful for automatic handling of FAQ as it reduces the linguistic variability and capture semantically related concept. It is also easy to adapt for FAQ. LSA does not require any sophisticated linguistic analyses and merely involves various vector operations. We evaluate LSA for FAQ on a corpus comprising 4905 FAQ items from a collection of 65000 mail conversations. Our results show that Latent Semantic Analysis, without linguistic analyses, gives results that are on par other methods for automatic FAQ.
