Semantic Caching in Location-Dependent Query Processing - Zheng, Lee (2001) (7 citations) (Correct)
....location. Xu et al. proposed a bit vector approach to identify the valid scope of the data, and investigated a couple of advanced methods of validating caches based on this approach [15] Semantic caches: A semantic cache stores data and a semantic description of the data in the mobile client [10]. The semantic description enables the cache to provide partial answers to queries which don t match the cache data exactly. As such, wireless traffic can be reduced and queries may be answered even in the case of disconnections. This characteristic makes a semantic cache an ideal scheme for ....

Location Dependent Query Processing - Seydim, Dunham, Kumar (2001) (6 citations) (Correct)
....Operands in a Simple Predicate havetobe ########## as being from the same domains. For example, one can use comparison operators as an operator and compare the attribute ######## with a constant Dallas but not with a constant 2001 since they havedi erent domains. A Compare Predicate de ned in [14] is a type of Simple Predicate. With a similar approach, we will not include #=in our studies, as it brings complexity in predicate evaluation. Since we are concentrating on the query processing issues of location dependent data, without loss of generality, we ignore the #= comparison. De ....
