NEPOMUK: Social Semantic Desktop NEPOMUK - Networked Environment for Personalized Ontology-based Management of Unified Knowledge, about 20 participating organizations with budget over 11 mln euros - Desktop: Help individuals in managing information on their PC - Semantic: Make content available to automated processing - Social: Enable exchange across individual boundaries Person Email friend Event Topic acquaintance Person WebSite Document colleague Image Personal Semantic Web: a semantically enlarged Social protocols NEPOMUK enabled intimate supplement to memory and distributed search peers Sergey Chernov, Tereza Iofciu, Wolfgang Nejdl, Xuan Zhou 01/05/19

NEPOMUK: The Society-Scale Semantic Web Application Today necessary technologies & communities exist: Standardized metadata: Semantic Web Scalable distributed infrastructure: P2P Computing Knowledge articulation and interaction: Desktop Technology Human centric information exchange: Online Social Networks Memex (Vannevar Bush) A memex is "a device in which an individual stores all his books, records, and communications”. Open Hypertext System (Doug Engelbart) “The open hyperdocument system is a standards-based, open source framework for developing collaborative, knowledge management applications.” WWW (Tim Berners-Lee) “There was a second part of the dream[…] we could then use computers to help us analyse it, make sense of what we re doing, where we individually fit in, and how we can better work together.” Challenge: Extension & merging of research streams Ontology driven distributed Social Networking Ontology driven Social Networking Semantic Desktop Social Semantic Desktop P2P networks Semantic Web Desktop/ Wiki Semantic P2P Social Networking Phase 1 Phase 2 Phase 3 Sergey Chernov, Tereza Iofciu, Wolfgang Nejdl, Xuan Zhou 01/05/19

Desktop Metadata Missing from INEX StoredFrom - Web links as sources of publications ReceivedFrom - Email activity information, emails containing publications EmailAnnotations - Email annotations (from sender) SearchKeyword - Search keywords, which were used at Web search engine to find the document OpenLast, MovedFrom - User action history in regard to the publications Annotation - User annotations Sergey Chernov, Tereza Iofciu, Wolfgang Nejdl, Xuan Zhou 01/05/19

Challenges for Designing a Dataset for Desktop Data obtained through logging Pros: real-data Cons: privacy issues, high level of user cooperation is required, low-scalability Data created through simulations Pros: scalable, easy-to-modify, cheap, less restrictions regarding privacy , existing datasets like INEX or Enterprise Track can be re-used Cons: can be based on wrong assumptions Sergey Chernov, Tereza Iofciu, Wolfgang Nejdl, Xuan Zhou 01/05/19

Our suggestion We invite everyone to collaborate in creating a dataset for desktop search It would be nice to consider additional metadata when designing new INEX collection Sergey Chernov, Tereza Iofciu, Wolfgang Nejdl, Xuan Zhou 01/05/19
