    The Internet and the Web have brought about a revolution in the way people live, obtain information, and interact with others. They have also brought about major changes in governance and commerce. Unfortunately, just as in the offline world, the transgressions of a minority of the people inhabiting the online world have made it costly and unhappy for the great majority of the people.

    Summary form only given. Though search on the World-Wide Web has focused mostly on unstructured text, there is an increasing amount of structured data on the Web and growing interest in harnessing such data. Moreover, structured data is starting to play a greater role in many of the social movements enabled by the Web, such as citizen participation in government. The paper describes several curren...

    Given a set of spatial points $D$ containing keywords information, a set of query objects Q and m query keywords, a top-k aggregate nearest keyword (ANK) query retrieves k objects from Q with the minimum sum of distances to its nearest points in D such that each nearest point matches at least one of query keywords. For example, consider there is a spatial database D which manages facilities (e.g.,... View full abstract»

    In recent years, there has been a growing need for location-based services (LBS), ranging from resource tracking to personal life assistance. The Moving k Nearest Neighbor (MkNN) query is a main problem in the LBS area, which retrieves the top k nearest neighbors while the query consumer moves. Considerable attention is attracted to this query type and a large number of studies are proposed recent... View full abstract»

    Flash memory has many advantages such as high performance, low electronic power, non-volatile storage and physical stability, over hard-disks. For this reason, flash memory has been deployed as data storage for mobile devices, including PDAs, MP3 players, laptop-computers and database systems. According to the cell type, flash memory can be divided into SLC(Single Level Chip) and MLC(Multi Level C... View full abstract»

    Flash disks have become a popular alternative for magnetic disks, due to their fast I/O speed and other features such as small-size, shock-resistance, energy-efficient and non-volatile. However, flash disks also have characteristics of out-of-place update and asymmetric I/O latencies for read, write, and erase operations, which introduce new challenges into the indexing mechanism for flash disks. ...

    MapReduce is a programming framework introduced by Google for large-scale data processing. It is usually used in a scan-centric fashion where all the data are split into blocks and Maps are generated for each block to scan and process the data in the block, then Reduces merge outputs from all the Maps. When a query intends to process only a subset of the data selected by a predicate, this brute-fo... View full abstract»

    Because the amount of information contained on the Deep Web is much larger than the surface web, how to use it well has become a popular problem to research. When a query is sent to a deep web resource and the data sources return few results or even no result, a proper query relaxation solution should be adopted to get more satisfactory results to users. In this paper, such a query relaxation solu... View full abstract»

    Keyword-based search exploits the exact match between the index terms of a query and documents. Thus, some documents, although they are relevant to the given query, may not be returned to users unless the documents include the index terms of the query. Some search engines use the authority of documents, which is derived from the links of documents, to help keyword-based search provide more accurat... View full abstract»

    This paper proposes a novel approach to service management and monitoring on the basis of service collaboration relations that can be extracted from service composition history. An undirected and weighted service collaboration network is constructed therefore. On the network, two abstractions are defined: service centrality, which measures a service's collaboration capability comparing to other se... View full abstract»

    In workflow management systems (WFMSs), time management plays an essential role in controlling the lifecycle of business processes. Especially, run-time analysis of time constraints is necessary to help process manager proactively detect possible deadline violations and appropriately handle these violations. Traditional time constraint analyses either present deterministic results which are too re... View full abstract»

    It is desired to have a system that can recommend news articles according to interests of a user, which would change with time. In this paper, we attempt to improve a news recommendation system with supervised classification by integrating a clustering method into the system in order to adapt flexibly to the variety of interests of a user. To follow the changes of interests with time, we need to m... View full abstract»
