  • Patent number: 7716352
    Abstract: An editing system that allows a user, when browsing the web, to select a web page, which is currently being viewed, to be edited. When a user navigates to a web page that the user can edit, the editing system displays an appropriate indication that the page can be edited. When the user selects to edit the currently displayed web page, the editing system enters an editing mode that allows the user to edit the web page within a browsing context. When in editing mode, the editing system may enable various toolbars and buttons within the window of the browser to facilitate the editing. When the user has completed the editing of the web page, the editing system automatically updates the web page at the web site.

  • Patent number: 7650335
    Abstract: A method and system for allowing end users to create a database and a user interface to interact with database data are provided. The database management system provides a database abstraction layer that hides the complexities of a database and vendor-specific implementation details from the end user, while still allowing the end user to perform powerful database tasks. The database management system allows an end user with little or no knowledge about databases to create, edit, and maintain a database without understanding the details behind the database. The database management system also provides a facility for the easy creation of web pages to access the database to provide features such as searching, data entry, and browsing data stored in the database.

  • Patent number: 7555472
    Abstract: A method and system for augmenting a corpus with documents on concepts not sufficiently covered within the corpus is provided. The augmentation system generates a corpus concept graph from the documents of a corpus. A corpus concept graph represents concepts of the documents as nodes and related concepts as links between nodes. To generate a corpus concept graph, the augmentation system identifies the concepts that are related within each document of the corpus and adds nodes and links to the corpus concept graph for related concepts. The augmentation system analyzes the corpus concept graph to determine whether the relatedness of concepts of the documents of the corpus is sufficient. If the relatedness of a pair of concepts is not sufficient, then the augmentation system attempts to identify documents not already in the corpus that are related to the concepts that are not sufficiently related.
