Priyanka Nikam, B.R. Nandwalkar
2015 International Journal of Computer Applications  
VISCOM classes collect the semantic content types and relations. Ontology based fuzzy video data semantic model which uses spatial and temporal relations in event and concept definition is proposed.  ...  In proposed system a semantic content extraction system that allows the user to query and regain objects, events, and concepts that are extracted automatically.  ...  To solve such problem some system uses ontology for representation and uses both techniques ontology and spatio temporal relations for semantic content extraction.  ...

The t4sql temporal query language

Carlo Combi, Angelo Montanari, Giuseppe Pozzi
2007 Proceedings of the sixteenth ACM conference on Conference on information and knowledge management - CIKM '07  
T4SQL is capable to deal with different temporal semantics (atemporal aka non-sequenced, current, sequenced, next) with respect to every temporal dimension.  ...  Moreover, T4SQL provides a novel temporal grouping clause and an orthogonal management of temporal properties when defining the selection condition(s) and the schema for the output relation.  ...  by the system.  ...

Cross-document event ordering through temporal, lexical and distributional knowledge

Borja Navarro-Colorado, Estela Saquete
2016 Knowledge-Based Systems  
The system deals with problems such as automatic event extraction, cross-document temporal relation extraction and cross-document event coreference resolution.  ...  Its main characteristic is the application of three different types of knowledge: temporal knowledge, lexical-semantic knowledge and distributional-semantic knowledge, in order to anchor and order the  ...  M A N U S C R I P T temporal relation assignment obtained by the TipSEM system.  ...

Cross-Document Event Ordering through Temporal Relation Inference and Distributional Semantic Models

Estela Saquete, Borja Navarro-Colorado
2017 Revista de Procesamiento de Lenguaje Natural (SEPLN)  
This paper focuses on the contribution of temporal relations inference and distributional semantic models to the event ordering task.  ...  Our system automatically builds ordered timelines of events from different written texts in English by performing first temporal clustering and then semantic clustering.  ...  Formally: coref (e1, e2) → (e1 t = e2 t ) ∧ (e1 s e2 s ) From this idea, our system is structured in four steps: Event and temporal relation extraction using Temporal Information Processing; 2.  ...

Compositional Semantics and Inference System for Temporal Order based on Japanese CCG [article]

Tomoki Sugimoto, Hitomi Yanaka
2022 arXiv   pre-print
Our system performs inference involving temporal order by using axioms for temporal relations and automated theorem provers.  ...  However, a Japanese NLI system for temporal order based on the analysis of formal semantics has not been sufficiently developed.  ...  The previous logicbased inference system (Onishi et al., 2020) introduced 169 axioms for these 13 temporal relations.  ...

A Framework for Temporal Content Modeling of Video Data Using an Ontological Infrastructure

B. Qasemizadeh, H. R. Haghi, M. Kangavari
2006 2006 Semantics, Knowledge and Grid, Second International Conference on  
Semantic video retrieval has emerged in the last decade as one of the most important features of pervasive multimedia systems.  ...  In this paper, a novel framework for temporal semantic video modeling based on ontologies is introduced.  ...  Also in the current version, the proposed system do not support semantic web languages e.g. OWL. We will adopt the system with these languages to benefit from the future semantic web in our system.  ...

2012 Proceedings of the 27th Annual ACM Symposium on Applied Computing - SAC '12  
These semantics allow one to specify how the system must manage temporal and spatial dimensions for evaluating the queries.  ...  In [4] a framework for modeling spatio-temporal data in relational databases has been proposed. The model is based on the notions of temporal, spatial, and spatio-temporal granularities.  ...  These semantics allows one to specify how the system has to manage temporal dimensions in order to evaluate queries. The proposed semantics for temporal querying are defined on time points.  ...

An architecture for supporting interoperability among temporal databases [chapter]

Claudio Bettini, X. Sean Wang, Sushil Jajodia
1998 Lecture Notes in Computer Science  
We propose a multidatabase architecture where an appropriate formalization of the intended semantics is associated with each temporal relation and temporal database.  ...  We also describe how the temporal mediator can provide a user interface to the multidatabase system allowing temporal queries in terms of arbitrary granularities and involving relations in different TDBMS  ...  Semantic assumptions used in our multidatabase system architecture are related to the idea of "semantic values" [SSR94] . A semantic value is a value that has an associated environment.  ...

Snapshot semantics for temporal multiset relations

Anton Dignös, Boris Glavic, Xing Niu, Michael Böhlen, Johann Gamper
2019 Proceedings of the VLDB Endowment  
Snapshot semantics is widely used for evaluating queries over temporal data: temporal relations are seen as sequences of snapshot relations, and queries are evaluated at each snapshot.  ...  We introduce a novel temporal data model based on K-relations that overcomes these bugs and prove it to correctly encode snapshot semantics.  ...  system for snapshot semantics over snapshot K-relations.  ...

Logical Specification of Real-Time Granular Systems in an Object Oriented Language

Emanuele Ciapessoni, Edoardo Corsetti, Manlio Migliorati, Elena Ratto
1993 International Joint Conference on Artificial Intelligence  
This paper presents the semantics of TRIO*, an object oriented language devoted to specify realtime systems referring to different time granularities.  ...  TRIO* semantics is expressed by translation into a logical framework supporting the notion of time granularity. Such a semantics provides the executability of object oriented specifications.  ...  Introduction The aim of the paper is to present the semantics of TRIO*, an object oriented language, devoted to specify real-time systems, in which several temporal granularities can be referred.  ...
