Exploring the Impact of Negative Sampling on Patent Citation Recommendation

2023, Dessi, Rima, Aras, Hidir, Alam, Mehwish

Due to the increasing number of patents being published every day, patent citation recommendations have become one of the challenging tasks. Since patent citations may lead to legal and economic consequences, patent recommendations are even more challenging as compared to scientific article citations. One of the crucial components of the patent citation algorithm is negative sampling which is also a part of many other tasks such as text classification, knowledge graph completion, etc. This paper, particularly focuses on proposing a transformer-based ranking model for patent recommendations. It further experimentally compares the performance of patent recommendations based on various state-of-the-art negative sampling approaches to measure and compare the effectiveness of these approaches to aid future developments. These experiments are performed on a newly collected dataset of US patents from Google patents.

Towards Analyzing the Bias of News Recommender Systems Using Sentiment and Stance Detection

2022, Alam, Mehwish, Iana, Andreea, Grote, Alexander, Ludwig, Katharina, Müller, Philipp, Paulheim, Heiko, Laforest, Frédérique, Troncy, Raphael, Médini, Lionel, Herman, Ivan

News recommender systems are used by online news providers to alleviate information overload and to provide personalized content to users. However, algorithmic news curation has been hypothesized to create filter bubbles and to intensify users' selective exposure, potentially increasing their vulnerability to polarized opinions and fake news. In this paper, we show how information on news items' stance and sentiment can be utilized to analyze and quantify the extent to which recommender systems suffer from biases. To that end, we have annotated a German news corpus on the topic of migration using stance detection and sentiment analysis. In an experimental evaluation with four different recommender systems, our results show a slight tendency of all four models for recommending articles with negative sentiments and stances against the topic of refugees and migration. Moreover, we observed a positive correlation between the sentiment and stance bias of the text-based recommenders and the preexisting user bias, which indicates that these systems amplify users' opinions and decrease the diversity of recommended news. The knowledge-aware model appears to be the least prone to such biases, at the cost of predictive accuracy.

Verwertungsgesellschaften und Open Content – Schnittmengen und Friktionen

2023, Rack, Fabian, Fischer, Georg, Klingner, Stephan, Zill, Malte

Inhalte gegen Geld lizenzieren und an VG-Ausschüttungen teilhaben einerseits, Inhalte kostenlos der Allgemeinheit als »Open Content« zur Verfügung stellen andererseits – nur scheinbar ein Widerspruch. Der Beitrag zeigt an den Beispielen Musik und Text, wo sich beide Ansätze treffen und inwieweit sie miteinander vereinbar sind. Er plädiert dafür, die Vereinbarkeit der Ansätze zu stärken und Unsicherheiten in der praktischen Anwendung abzubauen.

A Data Model for Linked Stage Graph and the Historical Performing Arts Domain

2023, Tietz, Tabea, Bruns, Oleksandra, Sack, Harald, Bikakis, Antonis, Ferrario, Roberta, Jean, Stéphane, Markhoff, Béatrice, Mosca, Alessandro, Nicolosi Asmundo, Marianna

The performing arts are complex, dynamic and embedded into societal and political systems. Providing means to research historical performing arts data is therefore crucial for understanding our history and culture. However, currently no commonly accepted ontology for historical performing arts data exists. On the example of the Linked Stage Graph, this position paper presents the ongoing process of creating an application-driven and efficient data model by leveraging and building upon existing standards and ontologies like CIDOC-CRM, FRBR, and FRBRoo.

Toward a Comparison Framework for Interactive Ontology Enrichment Methodologies

2022, Vrolijk, Jarno, Reklos, Ioannis, Vafaie, Mahsa, Massari, Arcangelo, Mohammadi, Maryam, Rudolph, Sebastian, Fu, Bo, Lambrix, Patrick, Pesquita, Catia

The growing demand for well-modeled ontologies in diverse application areas increases the need for intuitive interaction techniques that support human domain experts in ontology modeling and enrichment tasks, such that quality expectations are met. Beyond the correctness of the specified information, the quality of an ontology depends on its (relative) completeness, i.e., whether the ontology contains all the necessary information to draw expected inferences. On an abstract level, the Ontology Enrichment problem consists of identifying and filling the gap between information that can be logically inferred from the ontology and the information expected to be inferable by the user. To this end, numerous approaches have been described in the literature, providing methodologies from the fields of Formal Semantics and Automated Reasoning targeted at eliciting knowledge from human domain experts. These approaches vary greatly in many aspects and their applicability typically depends on the specifics of the concrete modeling scenario at hand. Toward a better understanding of the landscape of methodological possibilities, this position paper proposes a framework consisting of multiple performance dimensions along which existing and future approaches to interactive ontology enrichment can be characterized. We apply our categorization scheme to a selection of methodologies from the literature. In light of this comparison, we address the limitations of the methods and propose directions for future work.

From Floppy Disks to 5-Star LOD: FAIR Research Infrastructure for NFDI4Culture

2023, Tietz, Tabea, Bruns, Oleksandra, Söhn, Linnaea, Tolksdorf, Julia, Posthumus, Etienne, Steller, Jonatan Jalle, Fliegl, Heike, Norouzi, Ebrahim, Waitelonis, Jörg, Schrade, Torsten, Sack, Harald

NFDI4Culture is establishing an infrastructure for research data on material and immaterial cultural heritage in the context of the German National Research Data Infrastructure (NFDI) in compliance with the FAIR principles. The NFDI4Culture Knowledge Graph is developed and integrated with the Culture Information Portal to aggregate diverse and isolated data from the culture research landscape and thereby increase the discoverability, interoperability and reusability of cultural heritage data. This paper presents the research data management strategy in the long-term project NFDI4Culture, which combines a CMS and a Knowledge Graph-based infrastructure to enable an intuitive and meaningful interaction with research resources in the cultural heritage domain.

On the Impact of Temporal Representations on Metaphor Detection

2022, Giorgio Ottolina, Matteo Palmonari, Manuel Vimercati, Mehwish Alam, Calzolari, Nicoletta, Béchet, Frédéric, Blache, Philippe, Choukri, Khalid, Cieri, Christopher, Declerck, Thierry, Goggi, Sara, Isahara, Hitoshi, Maegaard, Bente, Mariani, Joseph, Mazo, Hélène, Odijk, Jan, Piperidis, Stelios

State-of-the-art approaches for metaphor detection compare their literal - or core - meaning and their contextual meaning using metaphor classifiers based on neural networks. However, metaphorical expressions evolve over time due to various reasons, such as cultural and societal impact. Metaphorical expressions are known to co-evolve with language and literal word meanings, and even drive, to some extent, this evolution. This poses the question of whether different, possibly time-specific, representations of literal meanings may impact the metaphor detection task. To the best of our knowledge, this is the first study that examines the metaphor detection task with a detailed exploratory analysis where different temporal and static word embeddings are used to account for different representations of literal meanings. Our experimental analysis is based on three popular benchmarks used for metaphor detection and word embeddings extracted from different corpora and temporally aligned using different state-of-the-art approaches. The results suggest that the usage of different static word embedding methods does impact the metaphor detection task and some temporal word embeddings slightly outperform static methods. However, the results also suggest that temporal word embeddings may provide representations of the core meaning of the metaphor even too close to their contextual meaning, thus confusing the classifier. Overall, the interaction between temporal language evolution and metaphor detection appears tiny in the benchmark datasets used in our experiments. This suggests that future work for the computational analysis of this important linguistic phenomenon should first start by creating a new dataset where this interaction is better represented.

Data Steward Service Center (DSSC): FAIRagro RDM-Expertise Hub

2023, Svoboda, Nikolai, Vedder, Lucia, Böhm, Franziska, Möller, Markus, Rey-Mazón, Elena, Schmidt, Marcus, Lindstädt, Birte, Stahl, Ulrike

The Data Steward Service Center (DSSC) is the central institution within FAIRagro to develop data management tools based on the needs of the scientific community. The DSSC organizes the continuous exchange of RDM knowledge and experience with other institutions, channels user requests from the community, and transfers knowledge from the FAIRagro task areas to the FAIRagro data stewards. FAIRagro data stewards are experts in the field of RDM for agrosystems research supervising and will train data curators in our community. Data stewards have core competencies in research data management (e.g., cross-scale from genes, phenomics, management to region; sensitive data, remote sensing, time series, plant, soil and related FAIRagro data). Knowledge and expertise is pooled to provide the full range of expertise to the community in one place to foster the coalescence of the community. The DSSC is headed by a coordinator and will house five data stewards, who are active in the community e.g. train data curators, give legal support. In the course of the project, further institutional or project data stewards will be integrated and the pool of experts will be further expanded. The network to the other NFDI consortia is continuously growing.

About Migration Flows and Sentiment Analysis on Twitter Data: Building the Bridge Between Technical and Legal approaches to data protection

2022, Gottschalk, Thilo, Pichierri, Francesca, Rigault, Mickaël, Arranz, Victoria, Siegert, Ingo

Sentiment analysis has always been an important driver of political decisions and campaigns across all fields. Novel technologies allow automatizing analysis of sentiments on a big scale and hence provide allegedly more accurate outcomes. With user numbers in the billions and their increasingly important role in societal discussions, social media platforms become a glaring data source for these types of analysis. Due to its public availability, the relative ease of access and the sheer amount of available data, the Twitter API has become a particularly important source to researchers and data analysts alike. Despite the evident value of these data sources, the analysis of such data comes with legal, ethical and societal risks that should be taken into consideration when analysing data from Twitter. This paper describes these risks along the technical processing pipeline and proposes related mitigation measures.
