Abstract: This disclosure describes, generally, methods and systems for determining a natural hierarchy for a data set. The method determines one or more pair-wise combinations within the data set. The one or more pair-wise combinations each include a first field and a second field from the database. The method then determines a distinct count for each entry in the first field grouped by the second field of the one or more pair-wise combinations, and determines that the distinct counts for each entry has a value equal to one. The method further includes based on the determination that the distinct counts for each entry have a value equal to one, setting the first field in the pair-wise combination as the parent and the second field in the pair-wise combination as the child in a default hierarchy for the data set.

Abstract: The invention concerns an improved electronic mail system, wherein incoming mail is automatically sorted into mailboxes, based on criteria defined by the user. In addition, the user can rank the mailboxes in order of importance, and the mailboxes are presented to the user in the order of rank. The user can also establish thresholds for any measurable characteristic of a mailbox. For example, one measurable characteristic may be the total number of unread messages. The user may choose to be informed when the total number of unread messages exceeds a threshold. If the threshold is set to ten, for example, then, when the eleventh message is received, the system triggers an alarm, notifying the user. The system also includes an interface which displays multiple windows to the user simultaneously, showing not only the contents of mail messages, but also other information about the user's mail, such as the ranking of the mailboxes and the criteria for triggering alarms.

Abstract: A technique is provided for passively browsing the Internet or an intranet by displaying images from web pages on a user's display screen. The user can select an image by clicking on it using a pointer manipulated by a mouse or trackball. A mapping list is maintained that maps the image universal resource locator (URL) for each image to the URL of the web page containing the image. Using the mapping list, the user's web browser can be driven to the web page associated with the image selected by the user. A group of web pages may be defined based on the results of a search, by entering URLs for sites or web pages of interest, using a bookmarks file, based on the currently displayed web page in a web browser, or by determining which web pages are associated with the images stored in an image cache.

Abstract: An information retrieval method wherein users may submit a query via a graphical bitmapping technique. The user provides an information retrieval system with a bitmap of a printed, written, or graphical query by either scanning the query with a graphical scanner, or employing a standard facsimile transmission machine. The information retrieval system then performs an optical image/character recognition process upon the received bitmap to determine the content of the query, information is then retried based upon the recognized characters and images. In a particular method of the invention, the user is provided with a bitmap of the retrieved information.

Abstract: Interactive Methods and apparatus for studying similarities of values in very large data sets. The methods and apparatus employ a dotplot in an interactive graphical user interface to make the relationship between the similarities and the data set visible. A variety of filtering, weighting, and compression techniques make it possible to employ the dot plot with sequences of more than 10,000 tokens and to interactively magnify the dot plot, change weighting and display quantization, and view the underlying data. Also disclosed is a technique which is employed in the apparatus for identifying long sequences of similar tokens. The apparatus is used in the study of large bodies of text and code.

Abstract: A method of analyzing a plurality of code segments to determine the similar static and dynamic features of the code segments compares the static and dynamic features of each of the code segments. Each code segment is comprised of one or more lines of program instructions. One or more predetermined static attributes are extracted from each code segment. Each code segment is then run so that the dynamic attributes of the code segment can be determined. The dynamic attributes are extracted from each code segment and a distance function is computed which is based on the extracted static and dynamic attributes for a given pair of code segments. The distance function produces a distance measurement which indicates the relative degree of similarity between the given pair of code segments.
