Partition semantics for relations
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. ...

A lexical metaschema for the UMLS semantic network
2005
Artificial Intelligence in Medicine
The comparison between the lexical partition and the semantic partition shows that they have very low similarity. ...
Objective: A metaschema is a high-level abstraction network of the UMLS's Semantic Network (SN) obtained from a partition of the SN's collection of semantic types. ...
Acknowledgement We thank the anonymous reviewers for their insightful remarks which helped to enhance this work. ...

Ontology for Task-Based Clinical Guidelines and the Theory of Granular Partitions
[chapter]
2003
Lecture Notes in Computer Science
We used as our starting point a DAML+OIL-based ontology for the WHO guideline for hypertension management, comparing this with related guidelines and attempting to show that TGP provides a flexible and ...
The theory of granular partitions (TGP) is a new approach to the understanding of ontologies and other classificatory systems. ...
A4: If two cells within a partition overlap, then one is a subcell of the other. These axioms relate to a granular partition as a system of cells. ...

Data Partitioning for Semantic Web
2014
International journal of computer and communication technology
An experiment is devised to show effect of data partitioning technique on query performance. It demonstrates the query performance analysis for partitioning techniques applied. ...
Semantic web database is an RDF database. Tremendous increase can be seen in semantic web data, as real life applications of semantic web are using this data. ...
RELATED WORK Partitioning data for semantic web ensures better performance is stated by Daniel Abadi where he shows that a vertical partitioned schema achieves similar performance to the property

For present purposes it is only relevant that something in the structure of partitives provides the partitive relation, be it a null relational noun or the partitive preposition. ...

2D Arrangement-based Hierarchical Spatial Partitioning
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
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. ...

On the Structure of Indefinite Possessives

Semantics and Linguistic Theory
embedded DP7 and from their partitive semantics. ...
Under either approach, the availability of the contextual interpretation for possessive partitives like some of John's dogs in (7b) follows from their partitive semantics: partitive DPs are restricted ...
If the partitive hypothesis is abandoned, some other structural property of indefinite possessives must be resorted to in order to account for their semantic peculiarity. ...

Graph-based partitioning of ontology with semantic similarity
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 ...

In particular, indefinite possessives do not license contextual interpretations, which are instead available for the corresponding definite possessives and possessive partitives. ...

Doing so, we are able to refine the partitioning of the social graph with semantic processing and to label the activity of detected communities. ...
For instance, during the partitioning of a social network with tags related to web topics, the user can reject skos:narrower relations of web such as web skos:narrower semantic web, in order to reveal ...

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. ...
