چکیده
Multimedia database systems largely focus on the management of media of one particular type and suffer from inflexible architectures, which makes it difficult to adapt them to individual application needs. This paper gives an overview of METIS, a flexible multimedia database foundation for the unified management of media of arbitrary types, characterized by profound customizability. METIS can be customized to feature any media types, metadata attributes, and associations desired for media description and classification. The system offers frameworks supporting the integration of any query operators, similarity measures, and/or feature extraction algorithms required for media retrieval. METIS makes use of a persistence abstraction layer that allows one to change storage back-ends and includes a highly customizable web front-end for administration and media management tasks. Along with the concept of semantic packs, which allow the bundling of domain-specific customizations, METIS constitutes a ready-to-use but nevertheless highly adaptable database foundation for a wide range of multimedia applications.

Proseminar Multimedia-Databases & Retrieval: An introduction to METIS - a Flexible Database Foundation for Uni ed Media Management
This paper introduces the idea, architecture and purpose of METIS which is a exible and highly costumizable multimedia database. It is the result of pushing a truly multimedia approach in the landscape of mostly single-media oriented databases. METIS can be depicted as a comprehensive system to all kinds of media, their metadata attributes, internal connections and requirements in feature-gener...
متن کاملYlvi - Multimedia-izing the Semantic Wiki
Semantic and semi-structured wiki implementations, which extend traditional, purely string-based wikis by adding machine-processable metadata, suffer from a lack of support for media management. Currently, it is difficult to maintain semantically rich metadata for both wiki pages and associated media assets; media management functionalities are cumbersome or missing. With Ylvi, a semantic wiki ...
متن کاملEffects of the Soil-Foundation-Structure Interaction on the Component Demand Modifier Factor of Concrete Gravity Beams based on ASCE 41-06 Standard
The aim of the present paper is to evaluate the influence of the Soil- Foundation- Structure Interaction (SFSI) effects on the component demand modifier factor of concrete gravity beams based on ASCE 41-06 standard. To this end, the beam on the nonlinear Winkler foundation approach is employed which is a simple and efficient method. At first, four sets of 3-, 6-, 10- and 15-storey concrete mome...

This paper aims to study the influence of soil-structure interaction on plastic energy demand spectra directly derived from the energy-balance equations of soil-shallow-foundation structure with respect to an ensemble of far-field strong ground motions obtained from Pacific Earthquake Engineering Research (PEER) database and recorded on alluvium soil. The superstructure is modeled as a single-d...
متن کاملStudying Impact of Unified Power Flow Controller on improve transient stability by Improved Harmony Search Algorithm
Main contribution of this work is improving transient stability by installing Flexible AC Transmission System (FACTS) in power systems. For do this, Unified Power Flow Controller (UPFC) has been selected. Also a novel structure has been suggested to improve classic Harmony Search algorithm and suggested improved Harmony Search (iHS) algorithm. This algorithm has been used to obtain UPFC paramet...
