Semantic Web Search

Semantic Search

Semantic Search is a data searching technique in which a search query aims to not only find keywords but to determine the intent and contextual meaning of the words a person is using for search.

It’s a crucial aspect of SEO, as search engines like Google use semantic search principles to understand and deliver results based on search intent, rather than just raw text matching.

Concept Representation

Concept Representation is the process of translating the complex, multi-dimensional nature of real-world concepts into a format that a computer can understand.

It’s a key part of Semantic Search, as it allows search algorithms to understand the meaning and context of search queries.

This leads to more accurate and relevant search results.


Techniques for Concept Representation

Techniques for Concept Representation

There are several techniques for Concept Representation, including ontologies, taxonomies, and vector space models.

  • Ontologies define a set of concepts and the relationships between them. For example, an ontology for animals might define “dog” as a type of “mammal“, which is a type of “animal“.
  • Taxonomies are a type of ontology that classifies concepts into a hierarchy. For example, a taxonomy for a website might classify “Home“, “About Us“, and “Contact” as top-level pages, with further sub-pages under each.
  • Vector space models represent concepts as vectors in a multi-dimensional space. For example, the word “apple” might be represented as a vector that is close to “fruit” but far from “car“.
