Abstract: A tool to be used with a search engine for a information management system includes methods for refining, filtering, and organizing search queries and search results. A query tuner in the tool allows a user to automatically reformulate a query in order to find a reasonable number of matching documents from the search engine by selectively modifying individual search terms to be weaker or stronger and concurrently requesting a plurality of searches, each with a respectively different modified query. The tool also uses a dynamic filter which employs a dynamic set of record tokens to restrict the results of an arbitrary search query to selectively include or exclude records which correspond to the set of record tokens. The tool also includes a results organizer which aids the user in understanding and visualizing a large number of matching documents returned in response to a search query by clustering like items returned from the search.

Abstract: Relationships among a plurality of web pages are indicated to a plurality of users. Icons are displayed, each of which corresponds to one of the web pages. Data associated with each of the pages is maintained for each of the users. This data may exist in the web page or be entered as a notation by each user. Data maintained locally for one user can be provided to another user. Web pages which have already been accessed are also indicated. A map is provided to guide the user so that the user may know which web pages have been accessed, which web pages are to be accessed next and what each web page means to the user Icons are added to the map for each material accessed. Links between icons may be established by the user or by the creator of the map. These links are displayed on the map as a user traverses among the accessible materials.

Abstract: A method and concomitant apparatus for performing motion analysis on a sequence of images is disclosed. Initially, the sequence of images is received from a video source. The sequence of images captures a plurality of objects each moving along a trajectory in an area imaged by the video source. Motion information is extracted from the sequence of images for each of the plurality of objects. Spatial patterns are then determined from the extracted motion information.

Abstract: A management tool is disclosed which aids the user in controlling the flow of data from one database table to another in computer memory, particularly when both the potential amount of data and the number of programmed functions which can be performed upon or be controlled by the data are large.
