Partition semantics for relations

Stavros S. Cosmadakis, Paris C. Kanellakis, Nicolas Spyratos
1986 Journal of computer and system sciences (Print)  
We use set-theoretic partitions to assign semantics to relation schemes, relations, and dependencies.  ...  Finally, we provide a polynomial time test for consistency of a set of relations with a set of PDs.  ...  Thus attributes play the critical role in determining partition semantics for many relation schemes.  ...

Murat Yirci, Mathieu Brédif, Julien Perret, Nicolas Paparoditis
2013 Proceedings of the Sixth ACM SIGSPATIAL International Workshop on Computational Transportation Science - IWCTS '13  
Semantic objects such as buildings, sidewalks and roads are described by grouping other objects and partition elements with their semantic relationships.  ...  It proposes a hierarchical spatial surface partitioning, encoding the spatial partition with a 2D arrangement and structuring a generic hierarchy of semantic objects with a directed acyclic graph (DAG)  ...  The authors also would like to thank the CGAL project for providing brilliant building blocks for geometric data structures and algorithms which we heavily utilized in our implementations.  ...

SemTree: An index for supporting semantic retrieval of documents

Flora Amato, Aniello De Santo, Francesco Gargiulo, Vincenzo Moscato, Fabio Persia, Antonio Picariello, Silvestro Roberto Poccia
2015 2015 31st IEEE International Conference on Data Engineering Workshops  
In this paper, we propose SemTree, a novel semantic index for supporting retrieval of information from huge amount of document collections, assuming that semantics of a document can be effectively expressed  ...  We investigate the feasibility of our approach in a real case study, considering the problem of finding inconsistencies in documents related to software requirements and report some preliminary experimental  ...  The result is a partition tree in which some partitions are used just for routing and others for storing data.  ...

Graph-based partitioning of ontology with semantic similarity

Soudabeh Ghafourian, Amin Rezaeian, Mahmoud Naghibzadeh
2013 ICCKE 2013  
In this paper, we partition a given ontology according to its semantic and structure to accomplish reusability.  ...  In our work, more relationships are taken into account than other approaches that only consider hierarchical relations. We propose an agglomerative and a heuristic algorithm to partition ontologies.  ...  Furthermore, the subclass relations give some important information about classes, so these relationships have high semantic contribution for ontology partitioning but not as much as the equivalent relations  ...

Target definition is a process aimed at partitioning the potential audience of an advertiser into several classes, according to specific criteria.  ...  One of the most important is that easily understandable segments are not effective for marketing purposes due to their triviality, whereas more complex segmentations are hard to understand.  ...  With respect to a partition p, denoting as U p (N ) the set of users related to the native partitioning, as U p to the k-means partitioning, and as U p (S) the set of users related to the SBS partitioning  ...
