Semantic Search Using Constrained Spread Activation for Semantic Digital Library

The work presented includes a prototype that demonstrates semantic search using constrained spread activation for relationship inference for semantic digital library domain. A java applet forms the basic user interface for this prototype. The user submits search query which is expanded using semantic digital library domain ontology. Based on the expanded query, initial nodes are activated and the activation is made to travel to other nodes using the constrained spread algorithm. The spread is constrained by making use of the distance constraint, which is supplied by the user.. The semantic search proposed here is the combination of spread activation techniques with traditional search engines techniques to obtain its results.
