Information Retrieval Techniques based on Ontology for High Effectiveness
نویسندگان
چکیده
Information Retrieving is task of recuperating information with high relevance, precision and recall. Basic methods for information retrieval include Boolean Retrieval, Fuzzy retrieval, Vector Space model. Searching depends on matching keywords between user-query and document. Ontology can be used in information retrieval. In software engineering and information science, ontology is a formal naming and meaning of the types, properties, and interrelationships of the elements that truly or in a broad sense exist for a specific domain of discourse. Ontology provides us with vocabulary of terms. New terms and relations could be found out using the existing relations. Many Information retrieval techniques exist amongst which many depend on keywords. Relations between keywords are considered here so as to get higher precision and recall.

Developing 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 کاملSteganography Scheme Based on Reed-Muller Code with Improving Payload and Ability to Retrieval of Destroyed Data for Digital Images
In this paper, a new steganography scheme with high embedding payload and good visual quality is presented. Before embedding process, secret information is encoded as block using Reed-Muller error correction code. After data encoding and embedding into the low-order bits of host image, modulus function is used to increase visual quality of stego image. Since the proposed method is able to embed...
