Two Papers Accepted at RecSys, ISMIR

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.

Shared Tasks on Authorship Analysis at PAN 2020

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). 


TISMIR Article on Culture-Aware User Models

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.

DBIS co-organizes PAN Style Change Detection Task

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:

  • Was the given document written by multiple authors? (task 1)
  • For each pair of consecutive paragraphs in the given document: is there a style change between these paragraphs? (task 2)

More information about the task can be found on the task website

International Society for Music Information Retrieval Conference

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".

DBIS at MediaEval 2019

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 featured in Standort

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). 

New Bachelor and Master Thesis Topics Available

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.

Paper Acceptance

Hooray - DBIS got three papers accepted at major conferences last week:

  • Generating Cross-Domain Text Corpora from Social Media Comments (Benjamin Murauer, Günther Specht) got accepted at the Conference and Labs of the Evaluation Forum (CLEF 2019)
  • Hit Song Prediction: Leveraging Low- and High-Level Audio Features (Eva Zangerle, Ramona Huber, Michael Vötter, Yi-Hsuan Yang) got accepted at the 20th Conference of the International Society for Music Information Retrieval (ISMIR 2019)
  • Article Quality Classification on Wikipedia: Introducing Document Embeddings and Content Features (Eva Zangerle, Manuel Schmidt) got accepted at the 15th International Symposium on Open Collaboration (OpenSym 2019)

ASI-PropertyServer is now Open Source

As a result of years of cooperation between the Austrian Standards International Working Group 011.09 "Technical Drawing and Documentation in Building Construction" and the research project freeBIM, which has been supported for years by the Economic Development Department of the state of Tyrol and the FFG, the ASI-PropertyServer is now Open Source and hence freely available to all interested parties, developers and companies. The already free and unlimited use of the ASI-PropertyServer for the Austrian BIM standard A 6241-2 has thus been expanded to include the option to install it locally, to supplement own special libraries and to cooperate in further development. It can be found at https://github.com/asi-propertyserver and is coordinated by the University of Innsbruck, Department of Databases and Information Systems (DBIS) under Univ. Prof. Dr. Günther Specht. 

The Economic Development Department of the state of Tyrol has recently confirmed that it will continue to support the further development of the project "freeBIM.connect" at the University of Innsbruck together with Tyrolean IT and industrial companies for the next two years.

ÖAW scholarship!

We are proud to announce that Benjamin's proposal for a DOC scholarship by the Österreichische Akademie der Wissenschaften has been accepted! This ensures that he can finish his PhD while remaining to do research in and for the department. Starting from July, the scholarship will provide financial support for two years.

StyleExplorer at ECIR 2019

This week, Michael is presenting our StyleExplorer tool at the 41st European Conference on Information Retrieval (ECIR 2019) in Cologne, Germany. StyleExplorer was developed by Thibault Gerrier as part of his Bachelor thesis and provides an online toolkit to analyze, visualize and compare arbitrary text documents. During the course of the ECIR conference, many participants expressed their interests and are looking forward to using it for their own research problems.
