Sentiment Analysis Using Common-Sense and Context Information
Algorithm 1
Build domain specific ontology from common-sense knowledge base.
INPUT Raw Assertions related to domain extracted from ConceptNet. | OUTPUT Ontology with domain-concepts | Step 1. Every relation r in the ontology is constructed by connecting two concepts i.e. concept1 (c1) and concept2 (c2). | Step 2. Generate a graph structure using these relations. Root of this graph is the domain itself. | Step 3. We connect two vertices V1 (i.e. concept1) and V2 (i.e. concept2) with an edge E (i.e. relation r). Connect all the | nodes extracted from ConceptNet to construct the ontology. | Step 4. First level nodes of this ontology are considered as new domain names and further synonyms are extracted from the | WordNet for expansion of the ontology. | Step 5. Repeat Steps 1–3 to construct ontology for each synonym word of the main domain. | Step 6. Merge all the extracted ontology to generate a single domain specific ontology. |
