To achieve this aim, a diverse set of novel and complementary analysis techniques have been integrated into a single, but extensible software platform on which such applications can be built. The platform combines state-of-the-art techniques for extracting facts, opinions and sentiment from multimedia documents, and unlike earlier platforms, it exploits both visual and textual techniques to support multimedia information retrieval. Foreseeing the usefulness of this software in the wider community, the platform has been made generally available as an open-source project. This paper describes the platform design, gives an overview of the analysis algorithms integrated into the system and describes two applications that utilise the system for multimedia information retrieval.}, author = {Dupplaw, David and Matthews, Michael and Johansson, Richard and Boato, Giulia and Costanzo, Andrea and Fontani, Marco and Minack, Enrico and Demidova, Elena and Blanco, Roi and Griffiths, Thomas and Lewis, Paul and Hare, Jonathon and Moschitti, Alessandro}, year = {2014}, volume = {3}, number = {2}, pages = {97--111}, } @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{Günther-Tobias2014-201512, title = {RTRGO: Enhancing the GU-MLT-LT System for Sentiment Analysis of Short Messages}, abstract = {This paper describes the enhancements made to our GU-MLT-LT system (Günther and Furrer, 2013) for the SemEval-2014 re-run of the SemEval-2013 shared task on sentiment analysis in Twitter.

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{Adesam-Yvonne2014-211376, title = {Koala – Korp’s Linguistic Annotations Developing an infrastructure for text-based research with high-quality annotations}, booktitle = {Proceedings of the Fifth Swedish Language Technology Conference, Uppsala, 13-14 November 2014}, author = {Adesam, Yvonne and Borin, Lars and Bouma, Gerlof and Forsberg, Markus and Johansson, Richard}, year = {2014}, }
