Taxonomy, Thesaurus and Ontology


Description of Services

Controlled vocabularies such as taxonomy, thesaurus and ontology are the main terminological resources that play a key role in developing the information architecture for online portals and search platforms.
Taxonomies provide the hierarchical categorization and classification of content into subject categories and also help to categorize and classify products and brands represented in online directories and product catalogues.

Thesaurus and lexicon provide the expanded terms of the basic taxonomic classification to incorporate user variants and improve the recall efficiency of the search and retrieval process.

Ontology provides the semantic description for the taxonomy terms and establishes the relationship between categories to facilitate conceptual search and natural language queries.

Specific Scope Offerings

Scope has developed its own taxonomy, thesaurus, lexicon and ontology for Medical and Life Science domains. We also provide customized solutions to meet the specific requirements of clients in the following areas: 

  • Taxonomy development and maintenance
  • Taxonomy Mapping/ Integration
  • Thesaurus and Lexicon development
  • Taxonomy expansion
  • Semantic labeling of taxonomy nodes through ontology
  • Development of niche taxonomies for medical specialties and consumer health portals
  • Automated content mining and vertical search solutions through the deployment of taxonomy and ontology

Lexicon development

Scope can develop lexicon for any domain, incorporating the following variants:
  • Word variants
  • Spelling variants
  • Morphological variants
  • Language variants

Thesaurus Construction

Scope has the expertise to developing thesauri as per the international standards for thesaurus constructions such as ANSI/ NISO Z39.19-2005 Guidelines, to facilitate both pre-coordinate and post-coordinate indexing of scholarly articles.

Some of the unique features of Scope's thesaurus development methodology are:
  • Multilevel Broader and Narrower Terms Hierarchical Displays
  • Construction of Equivalent Terms (Synonyms)
  • Construction of Associated Terms (Related Terms)

Ontology Development

Scope has a rich resource of Subject Matter Experts and Ontology Consultants to develop ontology for any vertical and its sub domains.

Scope's pre-built and customized ontology can be used in automated text mining and semantic processing applications for providing a search and retrieval platform, more advanced than the "Google" type keyword based search features. Some of the key features of Scope's ontology development are:
  • Conceptual definition for each node
  • Disambiguation of homonyms
  • Deconstruction of existing taxonomies and semantic labeling of taxonomy nodes.

Scope Methodology

Before embarking on any projects in this area, Scope's taxonomic experts and domain experts will have an in-depth discussion with the customer on their business objectives and specific requirements for the development of taxonomy, thesaurus and lexicon. 

Scope will study the existing information architecture and content management systems of the customer, do a gap analysis and identify the extent of enhancement and additions required in terms of taxonomy development, expansion and enrichment.

For developing the taxonomy, Scope uses a mix of automated crawlers and experienced web researchers to generate a very comprehensive list of terminologies used in a particular domain.

These terminological resources are further curated by our taxonomy experts, and a structured and granular taxonomy is developed depending on the level navigation and depth of search required by the customer.
Scope provides further value addition in the form of thesaurus, lexicon and ontology to improve the recall, precision and conceptual relevance of the search and retrieval process.

Scope has also developed online collaboration and web enablement tools for a real time, interactive and dynamic development process with all the stakeholders involved in the development process of taxonomy, thesaurus and ontology.

Leveraging its experience and expertise in taxonomy development, Scope has developed a pre-built taxonomy for organic chemistry domain and is in the process of developing taxonomies for bio technology, food processing and environmental science.

Client Benefits

The client can benefit with our one-stop solutions for all their requirements in the areas of taxonomy, thesaurus and ontology construction. Scope can help the customer right from the stage of requirements planning, design and development of the taxonomy, expansion and enrichment of the taxonomy with thesaurus and ontology, and regular maintenance and updation of taxonomies.

Scope can also use a combination of their internally developed taxonomies and their proprietary content mining tool, to develop advanced search and retrieval, and knowledge discovery platforms for extraction of conceptual entities; thematic clustering and dynamic visualization of results, and their relationships.
