Abstract: A client application installed on end user computers generates metadata from the content of web pages visited by end users and provides the metadata to a search engine. When an end user visits a web page, the end user's computer downloads and displays the web page to the end user. The client application may simultaneously access the web page content and generate this metadata in the form of a content signature of the web page from the web page content. The client application then provides the content signature to a search engine. The search engine may employ content signatures to identify new web pages to crawl and index. Additionally, the search engine may employ content signatures to identify changes to web pages and determine the crawl frequency of web pages.

Abstract: An adaptive data replication and caching system configured for deployment at the network edge. This system can include a data caching system configured to cache application data in a data store and to satisfy queries for application data from the cache. The system also can include a data replication system configured to replicate application data in the data store and to satisfy queries for application data against the replicated application data. Finally, the adaptive data replication and caching system can include a configurator for configuring portions of the data store for exclusive use by the data caching system and the data replication system.

Abstract: Methods, systems, and computer program products are provided for prefetching and caching portal information in a client application in a logically separated client/server computing environment. Before a user requests a specific portlet view to be displayed at the user's web browser, portlet information from a server is prefetched. The portlet information may include content data to be displayed in a portlet view, meta data describing how the content data will be displayed, and combinations of both content data and meta data. The prefetching step is performed on the client of the logically separated client/server computing environment. The client stores the prefetched portlet. Once the prefetched portlet information has been stored, upon a user request such as clicking on a link in a portlet view, the method retrieves the stored portlet information and displays the portlet information in a corresponding portlet view.

Abstract: A method, system and computer program product is provided for deploying software in a data processing system. A topology pattern is selected in which the selected topology pattern describes an arrangement of software and hardware devices. Augments to the selected topology pattern are received to form an augmented topology pattern after a selection of a selected topology pattern from a plurality of topology patterns. The augmented topology pattern is transformed into a set of deployable scripts, wherein the set of deployable scripts is used for the software deployment.
