We describe the method and discuss the many challenges encountered. We have loaded the data into an online database to make it accessible for anyone to explore and we present our own first explorations of it. The focus of the paper is thus twofold, covering pedagogical and methodological aspects of the lists’ construction, and linguistic aspects of the by-product of the project, the KELLY database. }, author = {Kilgariff, Adam and Charalabopoulou, Frieda and Gavrilidou, Maria and Bondi Johannessen, Janne and Khalil, Saussan and Johansson Kokkinakis, Sofie and Lew, Robert and Sharoff, Serge and Vadlapudi, R. and Volodina, Elena}, year = {2014}, volume = {48}, number = {1}, pages = {121--163}, } @inProceedings{Pilán-Ildikó2014-200967, title = {Reusing Swedish FrameNet for training semantic roles}, abstract = {In this article we present the first experiences of reusing the Swedish FrameNet (SweFN) as a resource for training semantic roles. We give an account of the procedure we used to adapt SweFN to the needs of students of Linguistics in the form of an automatically generated exercise. During this adaptation, the mapping of the fine-grained distinction of roles from SweFN into learner-friendlier coarse-grained roles presented a major challenge. Besides discussing the details of this mapping, we describe the resulting multiple-choice exercise and its graphical user interface. The exercise was made available through Lärka, an online platform for students of Linguistics and learners of Swedish as a second language. We outline also aspects underlying the selection of the incorrect answer options which include semantic as well as frequency-based criteria. Finally, we present our own observations and initial user feedback about the applicability of such a resource in the pedagogical domain. Students' answers indicated an overall positive experience, the majority found the exercise useful for learning semantic roles. }, booktitle = {Proceedings of LREC 2014, May 26-31, 2014, Reykjavik, Iceland}, author = {Pilán, Ildikó and Volodina, Elena}, year = {2014}, ISBN = { 978-2-9517408-8-4}, pages = {1359--1363}, } @inProceedings{Pil?n-Ildik?2014-10, title = "Rule-based and machine learning approaches for second language sentence-level readability.", booktitle = "Proceeding of the ACL 2014 9th Workshop on Innovative Use of NLP for Building Educational Applications, Baltimore, june 22-27 2014", author = "Pilán, Ildikó and Volodina, Elena and Johansson, Richard", year = "2014", isbn = "978-1-941643-03-7", url = "http://www.aclweb.org/anthology/W/W14/W14-1821.pdf", pages = "174--184", } @inProceedings{Volodina-Elena2014-201885, title = {A flexible language learning platform based on language resources and web services. }, abstract = {We present Lärka, the language learning platform of Språkbanken (the Swedish Language Bank).

Lärka can therefore be viewed as a case of a real-life language resource evaluation with end users.

In this work we merged methods and knowledge from machine learning-based readability research, from rule-based studies of Good Dictionary Examples and from second language learning syllabuses. The proposed selection methods have also been implemented as a module in a free web-based language learning platform. Users can use different parameters and linguistic filters to personalize their sentence search with or without a machine learning component assessing readability. The sentences selected have already found practical use as multiple-choice exercise items within the same platform. Out of a number of deep linguistic indicators explored, we found mainly lexical-morphological and semantic features informative for second language sentence-level readability. We obtained a readability classification accuracy result of 71%, which approaches the performance of other models used in similar tasks. Furthermore, during an empirical evaluation with teachers and students, about seven out of ten sentences selected were considered understandable, the rule-based approach slightly outperforming the method incorporating the machine learning model.}, booktitle = {Proceedings of the Ninth Workshop on Innovative Use of NLP for Building Educational Applications, June 26, 2014 Baltimore, Maryland, USA}, author = {Pilán, Ildikó and Volodina, Elena and Johansson, Richard}, year = {2014}, ISBN = {978-1-941643-03-7}, pages = {174----184}, } @inProceedings{Volodina-Elena2014-206132, title = {You get what you annotate: a pedagogically annotated corpus of coursebooks for Swedish as a Second Language.}, abstract = {We present the COCTAILL corpus, containing over 700.000 tokens of Swedish texts from 12 coursebooks aimed at second/foreign language (L2) learning. Each text in the corpus is labelled with a proficiency level according to the CEFR proficiency scale. Genres, topics, associated activities, vocabulary lists and other types of information are annotated in the coursebooks to facilitate Second Language Acquisition (SLA)-aware studies and experiments aimed at Intelligent Computer-Assisted Language Learning (ICALL). Linguistic annotation in the form of parts-of-speech (POS; e.g. nouns, verbs), base forms (lemmas) and syntactic relations (e.g. subject, object) has been also added to the corpus. In the article we describe our annotation scheme and the editor we have developed for the content mark-up of the coursebooks, including the taxonomy of pedagogical activities and linguistic skills. Inter-annotator agreement has been computed and reported on a subset of the corpus. Surprisingly, we have not found any other examples of pedagogically marked-up corpora based on L2 coursebooks to draw on existing experiences. Hence, our work may be viewed as “groping in the darkness” and eventually a starting point for others. The paper also presents our first quantitative exploration of the corpus where we focus on textually and pedagogically annotated features of the coursebooks to exemplify what types of studies can be performed using the presented annotation scheme. We explore trends shown in use of topics and genres over proficiency levels and compare pedagogical focus of exercises across levels. The final section of the paper summarises the potential this corpus holds for research within SLA and various ICALL tasks. }, booktitle = {NEALT Proceedings Series}, author = {Volodina, Elena and Pilán, Ildikó and Eide, Stian Rødven and Heidarsson, Hannes}, year = {2014}, volume = {22}, ISBN = {978-91-7519-175-1}, pages = {128--144}, }
