LogMap family participation in the OAEI 2018

Ernesto Jiménez-Ruiz, Bernardo Cuenca Grau, Valerie Cross
2018 International Semantic Web Conference  
We present the participation of LogMap and its variants in the OAEI 2018 campaign.  ...  This is our eight participation in the OAEI and the experience has so far been very positive. LogMap is one of the few systems that participates in (almost) all OAEI tracks.  ...  We would also like to thank Ian Horrocks, Alessandro Solimando, Anton Morant, Yujiao Zhou, Weiguo Xia, Xi Chen, Yuan Gong and Shuo Zhang, who have contributed to the LogMap project in the past.  ...

The Knowledge Graph Track at OAEI – Gold Standards, Baselines, and the Golden Hammer Bias [article]

Sven Hertling, Heiko Paulheim
2020 arXiv   pre-print
In 2018, we have started the Knowledge Graph track, whose goal is to evaluate the simultaneous matching of entities and schemas of large-scale knowledge graphs.  ...  The Ontology Alignment Evaluation Initiative (OAEI) is an annual evaluation of ontology matching tools.  ...  Only the systems of the LogMap family and POMAP++ do not return any alignments.  ...

MELT - Matching EvaLuation Toolkit [chapter]

Sven Hertling, Jan Portisch, Heiko Paulheim
2019 Lecture Notes in Computer Science  
Our contributions are twofold: We present an open source matching toolkit that integrates well into existing platforms, as well as an exemplary analysis of two OAEI 2018 tracks demonstrating advantages  ...  Compared to existing tools in the ontology matching domain, our framework offers detailed evaluation capabilities on the correspondence level of alignments as well as extensive group evaluation possibilities  ...  In the 2018 campaign, the same matchers mentioned above participated with the addition of LogMapBio, a matcher from the LogMap family [17] .  ...

Simulated Annealing-based Ontology Matching

Majid Mohammadi, Wout Hofman, Yao-Hua Tan
2019 ACM Transactions on Management Information Systems  
In contrast to populationbased EAs, the simulated annealing need not generate populations, which makes it significantly swift and memory-efficient for the ontology alignment problem.  ...  Ontology matching, or alignment, is one approach to make the heterogeneous information systems interoperable by finding the semantically identical concepts of two ontologies that are stated in distinct  ...  The preliminary implementation of SANOM participated in the OAEI 2017 (Mohammadi et al. 2017a) , and the current, enhanced implementation participates in the OAEI 2017.5 and 2018.  ...

A gold standard dataset for large knowledge graphs matching

Omaima Fallatah, Ziqi Zhang, Frank Hopfgartner
2020 International Semantic Web Conference  
In 2018, OAEI has introduced a specific track for KG matching systems. Nonetheless, a major limitation of the current benchmark is their lack of representation of real-world KGs.  ...  We believe that the dataset which we make public in this work makes the largest domain-independent gold standard dataset for matching KG classes.  ...  In contrast, the second to best performing matchers on the OAEI dataset, i.e., the LogMap family, obtained a recall of 0.79, which is the best recall on our gold standard.  ...

Interactive ontology matching based on partial reference alignment

Xingsi Xue, Xin Yao
2018 Applied Soft Computing  
AML, XMap and LogMap family can not return with very good alignments. The Pheno family reverted with huge but poor alignments.  ...  LogMap family [16] consists of three matching systems, i.e., LogMap, LogMapLt and LogMap-Bio .LogMapLt is a lightweight variant of LogMap, which only applies string matching techniques.  ...  Lessons Learned and Discussion In ICHEA, the user gets involved in the evolving process of the algorithm.  ...

Ernesto Jiménez-Ruiz, Oktie Hassanzadeh, Vasilis Efthymiou, Jiaoyan Chen, Kavitha Srinivas
2020 Lecture Notes in Computer Science  
In this paper, we report about the datasets, infrastructure and lessons learned from the first edition of the SemTab challenge.  ...  This task is a challenging problem for various reasons, including the lack of metadata (e.g., table and column names), the noisiness, heterogeneity, incompleteness and ambiguity in the data.  ...  We would like to thank the challenge participants, the ISWC & OM organisers, the AIcrowd team, and our sponsors (SIRIUS and IBM Research) that played a key role in the success of SemTab.  ...

Majid Mohammadi, Wout Hofman, Yao-Hua Tan
2018 IEEE Transactions on Knowledge and Data Engineering  
The statistical methods are then applied to benchmark and multifarm tracks from the ontology matching evaluation initiative (OAEI) 2015 and their results are reported and visualized by critical difference  ...  For comparison of two systems, the Wilcoxon signed-rank and McNemar's mid-p and asymptotic tests are recommended due to their robustness and statistical safety in different circumstances.  ...  Recently, more ontologies in other languages are also added so that ontologies in 10 different languages participated in the OAEI 2015.  ...
