چکیده
in addition to the multimedia content repository, the module assumes the existence of a domain knowledge base (KB) described by a domain ontology, and the availability of annotations of the content by KB entities. one of the fundamental novel features provided by the module is a ranking algorithm integrating the classic iR view of the notion of relevance and approximate search results, with the formal ontology-based notion of query answering.

Semiautomatic Image Retrieval Using the High Level Semantic Labels
Content-based image retrieval and text-based image retrieval are two fundamental approaches in the field of image retrieval. The challenges related to each of these approaches, guide the researchers to use combining approaches and semi-automatic retrieval using the user interaction in the retrieval cycle. Hence, in this paper, an image retrieval system is introduced that provided two kind of qu...
متن کاملMultifaceted Entity/Fact/Relation Retrieval via Semantic Search Interface based on Domain Knowledge Extraction
A significant kind of information search on the Web is concerned with finding entities of a specific type that satisfy certain semantic conditions. Nevertheless, the conventional keyword-based search mechanism commonly found on the Web does not enable the user to specify the semantic type/conditions for the entities sought, and accordingly does not return the entities as direct search results. ...
متن کاملDeveloping a BIM-based Spatial Ontology for Semantic Querying of 3D Property Information
With the growing dominance of complex and multi-level urban structures, current cadastral systems, which are often developed based on 2D representations, are not capable of providing unambiguous spatial information about urban properties. Therefore, the concept of 3D cadastre is proposed to support 3D digital representation of land and properties and facilitate the communication of legal owners...
متن کاملA Semantic Enhanced Model for effective Spatial Information Retrieval
A lot of information on the web is geographically referenced. Discovering and retrieving this geographic information to satisfy various users needs across both open and distributed Spatial Data Infrastructures (SDI) poses eminent research challenges. However, this is mostly caused by semantic heterogeneity in user’s query and lack of semantic referencing of the Geographic Information (GI) metad...
متن کاملCombining Fact and Document Retrieval with Spreading Activation for Semantic Desktop Search
The Semantic Desktop is a means to support users in Personal Information Management (PIM). It provides an excellent test bed for Semantic Web technology: resources (e. g., persons, projects, messages, documents) are distributed amongst multiple systems, ontologies are used to link and annotate them. Finding information is a core element in PIM. For the end user, the search interface has to be i...
