Semantic Image Annotation using Ontology And
SPARQL
A. Gauthami Latha, Ch. Satyanarayana, Y. Srinivas
Abstract: Based on user’s interest or requirements, the search
and retrieve images from large scale the databases, the content-
based image retrieval (CBIR) technique has become the primary
emerging area in research for digital image processing which
makes the visual contents to use.
Most promising tools for image searching are Google
Images and Yahoo Image search. They are used for annotations
based on textual of the images. In this, the images are annotated
manually with the help of keywords and then the retrieval is
carried by using various search methods based on text. Due to
this method, the system performance is too low. Therefore, CBIR
goal is to construct Image Ontology. The Ontology extracts the
relevant images from the database by using low-level features
like texture, shape and color.
In multimedia technology, the challenging task is to
retrieve the relevant images from an image database. For
representation, organization and retrieving of images, the
searching approaches based on semantic provide effective and
efficient results by using image ontology. In this paper, protege
software shows us how to create ontology and SPARQL query
language provides semantic annotation for images. In addition to
this, OntoViz and OntoGraph were used to generate Ontology
in a graphical form for the relevant application.
Keywords - Image Annotation, Ontology, OntoGraph,
OntoViz, OWL, Protégé Semantic, and SPARQL.
I. INTRODUCTION
In the universe, Web (WWW) is huge database. This
discovers files, documents, images etc. for the human. The
current search is based on keyword where the machines are
lacking in understanding the meaning and relationships
among the data. It lacks in semantic structure, where the
components scalability and interdependency is maintained .
In turn, returns the results for the input query using the
hyperlinks among resources and may also retrieve
irrelevant information to the user.
With the help of hyperlinks, the resources are
accessed, where the content is available on the web and
here the disadvantage is, the information is in machine
readable form which fails in making the machine
understand. Therefore, effective search or retrieval of
information has becomes highly crucial. In context of given
query, the process of extracting relevant results is defined
as information retrieval explicitly. We can extract keywords
by using various information retrieval techniques.
Therefore new search strategies are to be adopted.
Semantic based search provides appropriate and
relevant results than that of traditional keyword based
search. The efficiency of semantic based search depends on

the ontology [1]. The process of representation by
making use of the properties and relationships among the
images are termed as ontology and it is constructed by
considering the level of human understanding. Ontology is
constructed by making use of the low-level features like
texture, color and shape of images which replicates human
understanding. Therefore ontology is considered as more
useful for retrieval of images that are semantic based.
If the feature count varies from high to low, then
the ontology construction tends to be inefficient. The,
Resource Description Framework (RDF) framework is used
to describe and interchange metadata which provide
intelligent access among heterogeneous and distributed
information and also to construct domain ontology, Web
Ontology Language (OWL), is widely used. The two main
search approaches for image are:
1. Annotation Based
2. Content Based
Annotation based approach is based on keywords
or image metadata. [2]-[3]. Images Google Search is one of
the examples for this approach.
In this the search engine relies on the properties or
content of the image. The properties of the image include
name/title, creation date, format of the image, resolution,
copyright information and so on. Whereas, content based
metadata match with the properties of the entities depicted
like person, object, etc. The Semantic Web (SW) provides
framework which allows data to share and reuse for various
applications, enterprises etc and this termed as Resource
Description Framework (RDF).
To represent the knowledge resources, RDF is used and
to identify the resources, Uniform Resource Identifier
(URI) is used.
To represent the resources based on web and SPARQL
(Standard Protocol for RDF Query language), RDF
Schema is used, to obtain information or data from
RDF graphs. These graphs in-turn represented in
machine understandable form.
Semantic Search engines and browsers are used for
semantic traversal where the agents act as programs for
transferring the meaningful data.
The paper covers the keyword based annotation structure,
and ontology guided reasoning methods for the retrieval of
images. Our proposed approach has been implemented using
protégé for retrieval using. Images are retrieved using the
content description of the images by SPARQL query.
II. VISION OF SEMANTIC WEB
The idea of Semantic Web (SW) is proposed by Tim
Berners Lee in 1996.
The vision of Semantic Web
is to access data from the
