**3. Methodology**

The process and methods of this study are one of the important aspects for designing and creating taxonomy and ontology. In this original research paper, the matured level open-source tools and techniques have been selected for the creation of visual vocabulary. Apart from this it also explores how to construct a visual thesaurus in an offline and online environment on Ubuntu operating system for easy constructing of the different terms and relations such as narrower term, broader term, related term, used for, scope note, and so on. So, this paper consists of two parts such as online and offline for term relations.

Visuwords is an online visual graphical dictionary as well as controlled vocabulary tool. Actually it provides the visual interface of each word and its respective meaning on the basis of English grammar. This is very user-friendly for definition of any words from any subjects can be represented in a separate color dashboard. Wheel and zoom are possible by using the mouse. It explores the word synonym, derivation, and antonym to extend the meaning of any facets available in an web-based environment (https://visuwords.com/library). **Figure 1** represents the Visuwords interface in an online environment for visual graphic dictionary. It is possible to easily identify the noun, verb, adjective, and adverb for construction the

Linked Open Vocabularies is a new concept in semantic web ontology. It consists of large amount of dataset around 660 vocabularies as on March 10, 2019. It fully supports the OWL and RDF framework for better management and identification of the right link available in an online database. SPARQL endpoint is easily accessed by using this interface. Properties and classes can be done on the basis of ontology concept that is subject, predicate, and object (https://lov.linkeddata.es/dataset/ lov/). Here all the dataset belongs to the vocabulary content or element type. **Figure 2** represents the Linked Open Vocabularies interface in semantic web for

WebVOWL is a web-based ontology visualization open-source tool and is very interactive. This is written by high-level programming language named as Java which implements the visual notation and graphical interface of different nodal points in web ontology language. It explores the creation of ontology and combined forced graph in different formats such as JSON, RDF, and XML and other relevant file formats in an integrated semantic web environment (http://visualdataweb.de/ webvowl/). **Figure 3** represents the WebVOWL interface in semantic web for link-
