“…A first approach towards this end was the proposal to use plain XQuery [2] on top of an XML repository for MPEG-7 based multimedia content retrieval [11], without taking into account the peculiarities of the MPEG-7 description elements. The major limitation of this approach is that, using XQuery only, the different MPEG-7 metadata description elements cannot be fully exploited.…”

1 We present in this paper MP7QL, a powerful query language that we are developing for querying MPEG-7 descriptions, and a user preference model that allows for expressing preferences about every aspect of an MPEG-7 multimedia content description. The MP7QL queries may utilize the user preferences as context, thus allowing for personalized multimedia content retrieval. The user preference model supports multimedia Filtering and Search Preferences (FASP) that allow for expressing semantic preferences, preferences regarding the low-level visual features and preferences regarding media-related aspects (creation, classification, source etc). The proposed FASPs essentially are MP7QL queries, allow for the systematic integration of domain knowledge in the semantic preferences of the users and have the standard MPEG-7 FASPs as a special case. The MP7QL and the FASP model have been expressed using both XML Schema and OWL syntax. An implementation on top of an XML Repository is currently under way.

“…Thus, none of these systems can answer queries like "give me the MPEG-2 video segments created by the Eurosport that contain goals of France against Italy and contain a region similar to this in one of their frames" (the image region given as an example may be the face of a player). A first research effort for the establishment of a uniform and transparent MPEG-7 retrieval and filtering framework was the use of plain XQuery [23] on top of an XML repository for MPEG-7 based multimedia content retrieval [19]. This system does not make use of domain knowledge.…”

We present in this paper the MPEG-7 Query Language (MP7QL), a powerful query language that we have developed for querying MPEG-7 descriptions, as well as its compatible Filtering and Search Preferences (FASP) model. The MP7QL has the MPEG-7 as data model and allows for querying every aspect of an MPEG-7 multimedia content description. It allows the users to express the conditions that should hold for the multimedia content returned to them regarding semantics, low-level visual and audio features and media-related aspects. The MP7QL queries may utilize the users' FASP and Usage History as context, thus allowing for personalized multimedia content retrieval. The FASP model supported is compatible with the MP7QL and has the model of the standard MPEG-7 FASPs as a special case. The proposed FASPs essentially are MP7QL queries. Both the MP7QL and its compatible FASP model allow for the exploitation of domain knowledge encoded using pure MPEG-7 constructs. In addition, they allow the explicit specification of boolean operators and/or preference values in order to allow both the combination of the query conditions according to the user intentions and the expression of the importance of the individual conditions for the users. The MP7QL query results are represented as MPEG-7 documents, guaranteeing the closure of the results within the MPEG-7 space. The MP7QL and the FASP model have been expressed using both XML Schema and OWL syntax. An implementation of the MP7QL, on top of an XML Native Database is currently in progress. A real world-world evaluation study on the expressive power of the MP7QL shows that it covers both general purpose and domain specific requirements in multimedia content retrieval.
