DEXA: Supporting Non-Expert Annotators with Dynamic Examples from Experts [article]

Markus Zlabinger, Marta Sabou, Sebastian Hofstätter, Mete Sertkan, Allan Hanbury
2020 arXiv   pre-print
(referred to as Dynamic Examples for Annotation, DEXA).  ...  To overcome these limitations, we propose to support workers in addition to task-level examples, also with "task-instance level" examples that are semantically similar to the currently annotated data sample  ...  CONCLUSION We presented the Dexa annotation approach in which non-expert annotators are supported not only by task level annotation examples (as in Control) but also by dynamic, task-instance level examples  ...

ENIO: An Enterprise Application Integration Ontology

Athanasios Bouras, Panagiotis Gouvas, Gregoris Mentzas
2007 18th International Conference on Database and Expert Systems Applications (DEXA 2007)  
ENIO consists of an Upper EAI ontology, which is based on the DOLCE-SUMO alignment, with extensions called facets that cover several dimensions of the EAI domain.  ...  Each facet contains a relative meta-model that utilizes widely adopted standards 18th International Workshop on Database and Expert Systems Applications 1529-4188/07 $25.00  ...  Finding the best fitting super-concept in DOLCE for a SUMO term was therefore non-trivial.  ...

Axiom-Based Feedback Cycle for Relation Extraction in Ontology Learning from Text

Witold Abramowicz, Maria Vargas-Vera, Marek Wisniewski
2008 2008 19th International Conference on Database and Expert Systems Applications  
The ontology learning from text cycle consists of the consecutive phases of term, synonym, concept, taxonomy and relation extraction.  ...  The lessons indicate that the approach is complementary to supervised relation extraction methods and can be used in conjunction with them as a mean to bootstrap an initial ontology.  ...  Such non-monotonic reasoning capabilities seem crucial for systems with incomplete information about This work has been partially supported by Marie Curie Transfer of Knowledge Fellowship of the European  ...

Agile Browsing of a Document Collection with Dynamic Taxonomies

Sébastien Ferré
2008 2008 19th International Conference on Database and Expert Systems Applications  
The main function of dynamic taxonomies is to start with the full collection, and zoom-in to a small enough subset of items for direct inspection.  ...  Dynamic taxonomies and faceted search are increasingly used to organize and browse document collections.  ...  Querying by Examples A query can be determined by the selection of a subset of items, thus supporting querying by examples.  ...

A Comparison of Distance Measures for Clustering Video Sequences

Werner Bailer
2008 2008 19th International Conference on Database and Expert Systems Applications  
In order to determine nearly identical content, such as repeated takes of the same scene, very precise matching of sequences of features extracted from the video segments needs to be performed.  ...  In this paper we compare the performance of three distance measures for the task of clustering multiple takes of the same scene: Dynamic Time Warping (DTW) and two variants of Longest Common Subsequence  ...  Examples are several takes of a scene in rushes material or an event recorded from several very similarly positioned cameras, which is a typical case in news covered by different broadcasters.  ...
