, Dan (1-MAB; Boston, MA); Wang, Xiaoyang (1-SCA-C; Los Angeles, CA) Content-related interval queries on object histories.  ...  A particular property of object histories is that queries on them are typically multivalued. Many natural queries on object histories also return intervals of the original history.  ... 

Interval-based representation of spatio-temporal concepts [chapter]

Toshimi Tagashira, Toshiyuki Amagasa, Masayoshi Aritsugi, Yoshinari Kanamori
1997 Lecture Notes in Computer Science  
The definitions allow for uniform representations of the spatio-temporal queries on objects appearing in image sequences using intervals.  ...  This paper also gives examples of such queries for contents retrieval, and illustrates how they are performed in our method.  ...  Based on the definitions we can express spatio-temporal queries on objects appearing in image sequences, and can derive the answers for the queries from MBC data.  ...

An XML-Based Approach to Publishing and Querying the History of Databases

Fusheng Wang, Carlo Zaniolo
2005 World wide web (Bussum)  
We show that XML with XQuery can provide surprisingly effective solutions to the problem of supporting historical queries on past content of database relations and their evolution.  ...  This approach is very general, insofar as it can be used to store the version history of arbitrary documents and, for relational databases, it also supports queries on the evolution of their schema.  ...  Similarly, by coalescing the intervals of all empno, we get the interval of empno in the relation. Thus, the change history of every attribute of the relation is preserved.  ...

Diversifying Search Results Using Time [chapter]

Dhruv Gupta, Klaus Berberich
2016 Lecture Notes in Computer Science  
Our approach first identifies time intervals of interest to the given keyword query based on pseudo-relevant documents.  ...  It then re-ranks query results so as to maximize the coverage of identified time intervals. We present a novel and objective evaluation for our proposed approach.  ...  Formally, the objective is to maximize the probability that the user sees at least one result relevant to her time interval of interest.  ...

A survey on content-based retrieval for multimedia databases

A. Yoshitaka, T. Ichikawa
1999 IEEE Transactions on Knowledge and Data Engineering  
Implementation of the content-based retrieval facility is not based on a single fundamental, but is closely related to an underlying data model, a priori knowledge of the area of interest, and the scheme  ...  for representing queries.  ...  The point-based representation represents the position of objects by points on timeline, whereas the interval-based representation represents the relatedness of objects by means of the intervals of their  ...

Letter from the Chief Editor

Won Kim
1988 IEEE Data Engineering Bulletin  
Should the model incorporate objects? The standard relational model does not, but an argument can be made that object identity is crucial when time is modelled.  ...  difficulties with defining time, researchers focussed on formalizing, as carefully as possible, extensions or replacements for the relational model, algebra, and calculus.  ...  ACKNOWLEDGEMENT The authors would like to thank Professor Richard Snodgrass, University of North Carolina, for his comments and helpful criticism on an earlier draft of this paper.  ...

Abortable and query-abortable objects and their efficient implementation

Marcos K. Aguilera, Svend Frolund, Vassos Hadzilacos, Stephanie L. Horn, Sam Toueg
2007 Proceedings of the twenty-sixth annual ACM symposium on Principles of distributed computing - PODC '07  
Since this uncertainty is problematic, a query-abortable object supports a QUERY operation that each process can use to determine its last non-QUERY operation on the object that caused a state transition  ...  We introduce abortable and query-abortable objects, intended for asynchronous shared-memory systems with low contention.  ...  We now consider a different definition of non-triviality -one based on step contention instead of interval contention.  ...

A Temporal Knowledge Representation Model OSAM*/T and Its Query Language OQL/T

Stanley Y. W. Su, Hsin-Hsing M. Chen
1991 Very Large Data Bases Conference  
Most of the existing research on temporal databases have been based on the relational data model which has limited capabilities in modeling complex objects, constraints, and behavioral properties.  ...  It is an extension of the object-oriented semantic association model OSAM* to capture the concepts of time and history.  ...  One strategy is to evaluate the rest of the query against all these intervals; the other is to select only one interval for query evaluation.  ...

A Proactive Method for Content Distribution in a Data Indexed DHT Overlay [chapter]

Bassam A. Alqaralleh, Chen Wang, Bing Bing Zhou, Albert Y. Zomaya
2007 Lecture Notes in Computer Science  
Queries are distributed to these databases in a nonuniform way. Constructing content distribution networks for popular databases is effective for addressing the skew problem.  ...  Our experiments show that the approach is able to adapt quickly to flash query crowds and improve the query service quality of the systems.  ...  The first batch contains 2000 queries with mean generating interval 2ms; the second batch contains 4000 queries with mean generating interval 1.4ms and the third batch contains 6000 queries with mean interval  ...

Graph-Based Navigation Strategies for Heterogeneous Spatial Data Sets [chapter]

Andrea Rodríguez, Francisco Godoy
2006 Lecture Notes in Computer Science  
Querying heterogeneous spatial databases involves not only characterizing and comparing the information content of several databases, but also navigating or accessing the data sets with the query answer  ...  This work proposes a formalism that relates the information content of data sets by three basic types of correspondence relations: data equivalence, difference of data omission, and difference of data  ...  Using this formalism for query processing implies that one needs to characterize the information content of data sets associated with query windows in spatial databases.  ...

Querying the uncertain position of moving objects [chapter]

A. Prasad Sistla, Ouri Wolfson, Sam Chamberlain, Son Dao
1998 Lecture Notes in Computer Science  
In other words, the answer to a query depends not only on the database contents, but also on the time at which the query is entered.  ...  For example, suppose that there is a relation MOTELS (that resides, for example, in a satellite) giving for each motel its geographic-coordinates, room-price, and availability.  ...  the routes and speeds of moving objects and about the positions of statinary objects on the routes, then we can write an SQL query that computes a relation denoting the the ids of objects and the time  ...

Accommodating hybrid retrieval in a comprehensive video database management system

S.S.M. Chan, Qing Li, Yi Wu, Yueting Zhuang
2002 IEEE transactions on multimedia  
We also describe an experimental prototype being developed based on a commercial object-oriented toolkit using VC++ and Java.  ...  In this paper, we advocate a hybrid retrieval approach by integrating a query-based (database) mechanism with content-based retrieval (CBR) functions.  ...  Overall, the MPEG-7 standard and its related projects concentrate on content description and metadata attachment to multimedia data.  ...
