Validating Streaming XML Documents - Segoufin, Vianu (2002) (7 citations) (Correct)

....XML with respect to a DTD (see http: www.tibco.com) To our understanding, their approach is based on traditional parsing techniques enhanced with heuristics geared towards streaming inputs. A lot of work has been done on continuous queries over the Internet [6, 3] and on query subscription [16, 14]. In this scenario the query is fixed and outputs a stream of data produced on line from an incoming stream of data. The emphasis is on filtering and incremental maintenance of views, including aggregate functions. Another large body of work focuses on numerical data streams such as sensor data. ....

Several hybrid algorithms have also been introduced; these algorithms support certain types of operators, such as equality or inequalityoperators, set containment, or range tests (see [6] Other approaches support SQL oriented queries [7, 10], XMLquery languages [2, 4, 5] or IR like keyword queries [15] Our work is inspired by tree based indexing strategies for keyword based search, such as the ranked tree method [14] Closely related to our work is the Elvin system [13] which includes a quenching mechanism that discards unneeded ....

Other systems [4, 3] address the problem of achieving scalability for internet event noti cation systems but do not consider XML messages. Within the database community, Continuous queries (CQ) [6, 14] and triggers [19] have been developed to permit users to be noti ed with changes of interest that occurs in the database. Continuous queries are long running queries that automatically notify users of changes in the answer. Triggers are used to detect speci c changes on speci ed database states. ....

Monitoring XML Data on the Web - Nguyen, Abiteboul, Cobena, Preda (2001) (23 citations) (Correct)

....A main distinction is that we are not directly aware of the changes of data on the web. This modifies somewhat the issues and introduces real challenges in terms of fast reaction to changes [12] Continuous query system have recently triggered a lot of interest. For instance, The Conquer system [16, 9, 15] can run SQL like queries on a given HTML document. Like ours, their system provides email notification. However, building a complex SQL like query with Conquer requires having a solid knowledge of the web page that is being monitored. The factorization of database triggers is studied in [13] The ....

We conclude the paper with a discussion on the related work and a summary of our contributions. 1 2 Our Experience 2. 1 Construction of Wrappers In the Continual Queries project at OGI [7, 6, 8], we have built an event driven update monitoring system for Internet information sources. Motivated by our initial experience and frustration from writing wrapper programs by hand, we have developed an interactive software tool, called XWRAP, for semi automatic generation of XML enabled wrappers ....

Currently, several implementations of alerting services already exist for the different applicational domains, such as Salamander [MJS97] Siena [Car98] Keryx [BK97a, BK97b, LRW97] or OpenCQ [LPT99, PL98, LPR98] and Conquer [LPTH99] The underlying models of these services do not meet al..l requirements found in applications suitable for wide area networks, such as digital libraries. Additionally, the models for existing alerting services mainly cover the applications the services are designed for. In this paper, we provide ....

For example, the update monitoring application (Section 4. 1) is realized by the Continual Queries project [6, 5]. The distributed multimedia example (Section 4.2) is realized by the Quasar project. The successive versions of Infopipe implementation will be evaluated in concrete applications that we have been working on. 4 Application Scenarios 4.1 Update Monitoring The deluge of Internet information ....

Due to the space limitation, we omit the complete syntax of the CQ specification language in this paper. Readers who are interested in more details may refer to [26]. A WebCQ sentinel example is given by Example 1. Example 1 Consider a WebCQ sentinel track any change on the IMDb Movie of the Day from the front page of the Internet Movie Database Web site . The installation the through WebCQ GUI is shown partially in Figure 4. The user may select regular ....

....Grouping to WebCQ Original Work on sentinel grouping in WebCQ began due to several limiting factors in the first implementation of WebCQ. The original WebCQ was a novel implementation of a change detection system for web pages. It incorporated several ideas from our earlier work on the CQ project [26], applying the concept of continual queries to data available over the web. However, the first implementation of WebCQ consumed too many resources in managing and executing sentinels. The system relied on the Oracle 9i database system to manage all of the metadata, including user profiles, ....

This architecture was motivated by the need for providing scalable and reliable continual query processing, and the need for sharing information among structured, semi structured, and ....
