2019 Scientific-practical Workshop Information Technologies: Algorithms, Models, Systems  
We consider some perspective approaches for the deeplearning-based table detection, heuristic-based table structure recognition, rule-based table analysis, and knowledge-based table interpretation.  ...  Our application experience confirms that such solutions are demanded for populating databases and generating ontologies with tabular data being extracted from weakly and semi-structured documents.  ...  Additionally, ad-hoc heuristics can be handcrafted and tuned for various domain-specific PDF documents.  ...

Towards Aligning Multi-concern Models via NLP

Fatma Basak Aydemir, Fabiano Dalpiaz
2017 2017 IEEE 25th International Requirements Engineering Conference Workshops (REW)  
The design of large-scale complex systems requires their analysis from multiple perspectives, often through the use of requirements models.  ...  Many querying methods exist: Exact match: The ontology contains an entry that is an exact match of the noun. Contains: There is an entry in the ontology that contains the noun, e.g.  ...  This paper paves the way for future work. The focus group confirmed the need for different heuristics based on the individual preferences of the modelers.  ...

Breathing ontological knowledge into feature model synthesis: an empirical study

Guillaume Bécan, Mathieu Acher, Benoit Baudry, Sana Ben Nasr
2015 Empirical Software Engineering  
We develop six heuristics for clustering and weighting the logical, syntactical and semantical relationships between feature names.  ...  Numerous synthesis techniques and tools have been proposed, but only a few consider both configuration and ontological semantics of an FM.  ...  Key findings for RQ2. -The experiment demonstrates that an approach based on ontological heuristics provides the best support for producing ranking lists.  ...

2017 Communications in Computer and Information Science  
The architecture offers a holistic view of the main challenges involved in labeling data and generating prediction models for social services.  ...  A fundamental reason for this gap is the difficulty in labeling and annotating social services data.

Ordering Heuristics for Description Logic Reasoning

Dmitry Tsarkov, Ian Horrocks
2005 International Joint Conference on Artificial Intelligence  
We present a new architecture for Description Logic implementations, a range of new optimisation techniques and an empirical analysis of their effectiveness.  ...  ., configuration [McGuinness & Wright, 1998 ], and reasoning with database schemas and queries [Calvanese et al., 1998b; 1998a] ), they are perhaps best known as the basis for widely used ontology languages  ...  The idea is to make an initial guess based on an analysis of the syntactic structure of the ontology (it should be quite easy to distinguish GALEN-like ontologies from DOLCE and WineFood-like ontologies  ...

Toward MUI: Ontology assisted global identification of Audio Resources

Giovanni Tummarello, Christian Morbidoni, Dimitrios Kourtesis, Francesco Piazza, Paolo Puliti
2005 Semantic Web Applications and Perspectives  
For machine and individuals to successfully exchange annotations about audio resources, a technique is needed to provide these with stable identifiers.  ...  In this paper we propose ontological definitions of some identification problems and discuss the preliminary conceptual structure of the Music URI Infrastructure (MUI) project.  ...  completely uncorrelated tune.  ...

Fast and simple semantic class assignment for biomedical text

K. Bretonnel Cohen, Tom Christiansen, William A. Baumgartner Jr., Karin Verspoor, Lawrence Hunter
2011 Workshop on Biomedical Natural Language Processing  
A simple and accurate method for assigning broad semantic classes to text strings is presented.  ...  The method is to map text strings to terms in ontologies based on a pipeline of exact matches, normalized strings, headword matching, and stemming headwords.  ...  Future work The heuristics that we implemented for extracting headwords from OBO terms were very simple, in keeping with our initial goal of developing an easy, fast method for semantic class assignment  ...
