We are a subdivision of the Department of Computer Science at the University of Innsbruck.
Our passion lies in developing innovative methods for efficient data storage and analyses aiming to assist users and businesses to meet their information needs.
Eva will be co-organizing the PERSPECTIVES Workshop: Perspectives on the Evaluation of Recommender Systems at the ACM Recommender Systems Conference 2021 in Amsterdam, The Netherlands. Together with Christine Bauer and Alan Said. In this workshop, we aim to capture the current state of evaluation of recommender systems, and gauge whether there is, or should be, a different target that RS evaluation should strive for.
Our article titled "Leveraging Affective Hashtags for Ranking Music Recommendations" recently appeared in IEEE Transactions on Affective Computing (impact factor 7.512). Together with Yi-Hsuan Yang (Academia Sinica, Taiwan) and Chih-Ming Chen and Ming-Feng Tsai (both National Chengchi University, Taiwan), Eva extracted affective contextual information from hashtags that music listeners use to describe music on Twitter. The gathered information is modelled as a graph and via state-of-the-art network embedding methods, we learn latent feature representations of users, tracks and hashtags. Based on these representations, we propose eight ranking methods for personalized music recommendations.
DBIS is presenting two workshop papers at the MediaEval 2020 on Monday.
At 14:00, we will present our solution to Music mood and theme detiction, and at 16:00 we talk about our solution for detecting conspiracies regarding 5g and Corona.
The registration is free, so feel free to drop in and join the discussions.
This week, we finished two submissions to two challenges organized by the MediaEval benchmarking initiative.
In FakeNews: Corona virus and 5G conspiracy, the task is to classify Twitter messages into three categories, and determine whether they contain assumptions correlating 5G with the outbreak of the Corona virus, or not.
In Emotions and Themes in Music, we predict user-defined tags associated to music tracks by analyzing low-level audio features.
Stay tuned for the results of our approaches in these challenges, as well as our working notes.
Last week, two conference papers co-authored by DBIS member Eva Zangerle have been accepted at conferences:
The paper "Personality Bias of Music Recommendation Algorithms" together with Alessandro Melchiorre and Markus Schedl of JKU Linz has been accepted as a short paper at the 14th ACM Conference on Recommender Systems (acceptance rate for short papers: 20%). The paper "Pandemics, music, and collective sentiment: evidence from the outbreak of COVID-19" together with Meijun Liu and Xiao Hu (both University of Hong Kong) and Alessandro Melchiorre and Markus Schedl (both JKU Linz) has been accepted at the International Society for Music Information Retrieval Conference.
The tasks of the PAN workshop on authorship analyses have been features and presented at the European Conference on Information Retrieval (ECIR) 2020. At PAN, DBIS organizes one of four tasks, the Style Change Detection Task, which is already underway and is still open for new teams and submissions.
You can find the paper at ECIR in the proceedings of ECIR 2020 (Springer LNCS).
Our article "User Models for Culture-Aware Music Recommendation: Fusing Acoustic and Cultural Cues" together with Markus Schedl from JKU Linz, Austria has just been published by the Transactions of the International Society for Music Information Retrieval journal. In this article, we propose a novel approach to jointly model users by their musical preferences and cultural backgrounds. We describe the musical preferences of users by the acoustic features of the songs the users have listened to and characterize the cultural background of users by culture-related socio-economic features that we infer from the user’s country.
You can find the article here.
As in previous years, DBIS members are co-chairs of the PAN Style Change Detection task, co-located with CLEF 2020 (Conference and Labs of the Evaluation Forum).
The goal of the style change detection task is to detect changes in writing style to identify text positions within a given multi-author document at which the author switches. Particularly, given a document, we ask participants to answer the following two questions:
More information about the task can be found on the task website.
This week, the thirty-third Conference on Neural Information Processing Systems (NeuIPS) takes place. Together with Suzana Ilic and Asir Saeed, Eva has made a contribution to the Machine Learning for Creativity and Design Workshop, in which we present a generative adversarial network approach for the generation of creative contents such as poems, lyrics or metaphors: Creative GANs for generating poems, lyrics, and metaphors.
This week, Eva and Michael are at the 20th International Society for Music Information Retrieval Conference (ISMIR) in Delft, The Netherlands. At the conference, Eva will be a project guide at the WiMIR 2nd Annual Workshop, a satellite event of ISMIR 2019. She also served as co-chair for tutorials for the conference and together with Michael, she will present their paper "Hit Song Prediction: Leveraging Low- and High-level Features".
This week, Max is at MediaEval 2019 in Nice, France. MediaEval is a workshop consisting of various challenges in the area of multimedia information retrieval. Together with our partners from Academia Sinica and Taiwan AI Labs, DBIS co-authored two papers on the Emotion and Theme Recognition in Music Using Jamendo task. Max will present one of those papers (Recognizing Song Mood and Theme Using Convolutional Recurrent Neural Networks) on Tuesday.
Günther Specht is featured in the Standort magazine, where he discusses Building Information Management (BIM) and particularly, our freeBIM project.
This week, Benjamin and Eva are in Lugano for the CLEF conference (Conference and Labs of the Evaluation Forum, a central conference on evaluating information retrieval tasks) to present their works. Benjamin will present his full paper entitled "Generating Cross-Domain Text Corpora from Social Media Comments" at the main conference on Wednesday. Eva was task chair for the Style Change Detection task of the PAN@CLEF Challenge 2019 and will present the task and the participant's results as part of the PAN lab (Overview of the Style Change Detection Task at PAN 2019, Overview of PAN 2019: Bots and Gender Profiling, Celebrity Profiling, Cross-Domain Authorship Attribution and Style Change Detection).
We are happy to announce that new topics for Bachelor and Master theses are available now. They cover the whole spectrum of our research. You can choose from music, natural language and database related topics.
Take a look at our theses page for further details.
Hooray - DBIS got three papers accepted at major conferences last week:
