In this paper, we aim at tackling the problem of dynamic user profiling in the context of streams of short texts. Profiling users' expertise in such context is more challenging than in the case of long documents in static collection as it is difficult to track users' dynamic expertise in streaming sparse data. To obtain better profiling performance, we propose a streaming profiling algorithm (SPA). SPA first utilizes the proposed user expertise tracking topic model (UET) to track the changes of users' dynamic expertise and then utilizes the proposed streaming keyword diversification algorithm (SKDA) to produce top-k diversified keywords for profiling users' dynamic expertise at a specific point in time. Experimental results validate the effectiveness of the proposed algorithms.
SHFAYIM, Israel (Reuters) - Technology that has helped Israel's military drive tanks, guide and intercept missiles, and keep its computer systems secure is being redeployed in the development of driverless cars. Investment from firms seeking access to Israeli expertise in automated driving, much of it gathered by engineers during their conscription, is pouring into startups. U.S. chipmaker Intel, German auto supplier Continental, Samsung, Daimler, Ford Motor Co and GM are among those to have bought startups or set up their own development centers in Israel. Inexperience in car-making, distance from traditional auto centers and competition from other tech sectors for top staff are a challenge for investors. Israeli auto tech startups still raised almost as much as similar U.S. companies last year.
