Introduction

Ontology (知識地圖) The ontology is a collection of key concepts and their interrelationships collectively providing an abstract view of an application domain. An ontology is a formal, explicit specification of a shared conceptualization. Conceptualization Explicit Formal

Ontology (知識地圖) Ontology–explicit formal specifications of the terms in the domain and relations among them. An ontology contains a hierarchy of concepts within a domain and describes each concept’s property through an attribute-value mechanism. Relations between concepts describe additional logical sentence.

Characteristics of Ontology Formal Semantics Consensus of terms Machine readable and processable Model of real world Domain specific

Reasons to Develop Ontologies To share common understanding of the structure of information among people or software agents. To enable reuse of domain knowledge. To make domain assumptions explicit. To separate domain knowledge from the operational knowledge. To analyze domain knowledge.

Process of Developing an Ontology Developing an ontology includes: Determine the domain and scope of the ontology. Consider reusing existing ontologies. Enumerate important terms in the ontology. Define classes in the ontology and arrange the classes in a taxonomic (subclass-superclass) hierarchy. Define attribute and describe allowed values for these attribute. Fill in the values for attribute for instance.

Why Semantic Search? Mass information make user confused, current search engines are not good enough. (e.g. 腦科 v.s. 電腦科學) Quality is more important than Quantity Search by "what they means" not just "what they say" The user who has no idea about domain terminologies can’t find information easily.

Ontology Construction

Automatic Construction of OO Ontology Use object-oriented data model to represent ontologies. Follow object-oriented analysis procedure to build ontologies. Apply natural language processing technology to extract key terms from documents.

Automatic Construction of OO Ontology Apply SOM clustering technology to find concepts and instances. Apply data mining technology and morphological analysis to extract attributes, operations, and associations of instances. Aggregate attributes, operations, and associations of instances to class.
