Extraction of social context and application to personal multimedia exploration

摘要: Personal media collections are often viewed and managed along the social dimension, places we spend time at people see, thus tools for extracting using this information required. We present novel algorithms identifying socially significant termed spheres unobtrusively from GPS traces of daily life, label them as one Home, Work, or Other, with quantitative evaluation 9 months taken 5 users. extract locational co-presence these users formulate a measure tie strength based on frequency interaction, nature it occurs within. Comparative user studies multimedia browser designed to demonstrate utility metadata indicate usefulness simple interface allowing navigation filtering in terms. note application context is potentially much broader than personal management, including context-aware device behaviour, life logs, networks, location-aware services.
