Exploring Large Language Models for Product Attribute Value Identification
Kassem Sabeh, Mouna Kacimi, Johann Gamper +2
Product attribute value identification (PAVI) involves automatically identifying attributes and their values from product information, enabling features like product search, recomm…
An Empirical Comparison of Generative Approaches for Product Attribute-Value Identification
Kassem Sabeh, Robert Litschko, Mouna Kacimi +2
Product attributes are crucial for e-commerce platforms, supporting applications like search, recommendation, and question answering. The task of Product Attribute and Value Identi…
Indexing Temporal Relations for Range-Duration Queries
Matteo Ceccarello, Anton Dignös, Johann Gamper +1
Temporal information plays a crucial role in many database applications, however support for queries on such data is limited. We present an index structure, termed RD-index, to sup…
Upper Bounding the Graph Edit Distance Based on Rings and Machine Learning
David B. Blumenthal, Johann Gamper, Sébastien Bougleux +1
The graph edit distance (GED) is a flexible distance measure which is widely used for inexact graph matching. Since its exact computation is NP-hard, heuristics are used in practic…
Snapshot Semantics for Temporal Multiset Relations (Extended Version)
Anton Dignös, Boris Glavic, Xing Niu +2
Snapshot semantics is widely used for evaluating queries over temporal data: temporal relations are seen as sequences of snapshot relations, and queries are evaluated at each snaps…
Finding k-Dissimilar Paths with Minimum Collective Length
Theodoros Chondrogiannis, Panagiotis Bouros, Johann Gamper +2
Shortest path computation is a fundamental problem in road networks. However, in many real-world scenarios, determining solely the shortest path is not enough. In this paper, we st…
Model-Based Diagnosis with Qualitative Temporal Uncertainty
Wolfgang Nejdl, Johann Gamper
In this paper we describe a framework for model-based diagnosis of dynamic systems, which extends previous work in this field by using and expressing temporal uncertainty in the fo…
