ABSTRACT
Since social media era and Web 2.0 launch, personalized tools become a necessity. In this context, users need customized treatment caused by physical librarian’s absence. OPAC should response this by adopting better interface and functionalities. For example, OPAC will be using membership instead of visitor logs, enhancing search capabilities, maintaining query optimization and deploying semantic to learn member uses. Recent studies also have built some recommendation systems to help library users effectively identify their needed books. Combining search history, pattern-based search, and ontology as unified terminology and semantic inter-relations between concepts are some keywords on recent research (L.C.P.K.I. Liao, 2014).
