  4. Where we need to work on more Research Areas 이동주 명재석 • Query Management • Parser • Query Expansion • Using dictionary, context • Query Mediation • Service Combining • Hot to combine different services? • When different services should be combined? • * Context Monitoring • Keeps monitoring on data & logs • Generate service rules • Push requests to matcher by catching context • Data Monitoring • Log Monitoring • Service Rule Generation • Matcher • Recieves requests • Decides which algorithms to be used Provides what the algorithms need • Recommendation • Music Recommendation • Other contents? • Question & Answering • Semantic Search • * Log Management • What do we need to log? • Data(Ontology) Modeling • User • Contents • Context • Ontology Manager • Lets us see heterogeneous data, logs, etc (physical) as one integrated ontology that includes user, context, contents,… (logical) • Methodology : how to map heterogeneous databases to an ontology? • Configurations • Inference Engine • Knowledge Expansion • Add semantics to raw data • Inference new semantics from existing context • * Mediator (Dealing with heterogeneity) • Data Mediator • Log Mediator • Database to Ontology Mapping • Synchronization • Index Manager • Crawler • Crawls data from a wide range of sources and saves to databases properly • Focused Crawling • Opinion Mining 강승석 이재원 이철기 이동주 양정연 Many of us
