This paper presents an overview of the MPEG-7 Description Definition Language (DDL). The DDL provides the syntactic rules for creating, combining, extending and refining MPEG-7 Descriptors (Ds) and Description Schemes (DSs). In the interests of interoperability, the W3C’s XML Schema language, with the addition of certain MPEG-7-specific extensions, has been chosen as the DDL. This paper describ...

in this research, recognition of karstic water-bearing zones using the management of exploration data in kal-qorno valley, situated in the tepal area of shahrood, has been considered. for this purpose, the sequential exploration method was conducted using geological evidences and applying remote sensing and geoelectrical resistivity methods in two major phases including the regional and local s...

Our position is founded on two assumptions. First, we assume that the SQL data definition language (SQL-DDL) is capable of encoding substantial domain semantics, albeit not in ways syntactically accessible to inference engines. Second, the layered architecture of the Semantic Web, a.k.a. the layer cake, transcends the Semantic Web. In other words, we assume that the hierarchy of increasingly ex...

Electrical load forecasting is very crucial for electrical power systems’ planning and operation. Both buildings’ demand meteorological datasets may contain hidden patterns that are required to be investigated studied show their potential impact on forecasting. The data analyzed in this study through different mining techniques aiming predict the of a factory located Riyadh, Saudi Arabia. used ...
