A method for searching a document directory hierarchy which partitions a user-initiated search. The document directory hierarchy comprises a plurality of document directories stored in a tree data structure. Each of the plurality of document directories corresponds to a category within a class hierarchy and stores at least one document. A user query comprising one or more search terms is accepted from an input device. If the user query includes a user-selected category, a directed search is performed. However, if the user query does not include a user-selected category, an undirected search is performed. The directed search confines the search to one of the plurality of document directories corresponding to the user-selected category, and returns relevant documents within the user-selected category. The undirected search is performed within each of the plurality of document directories within the document directory hierarchy, and returns relevant categories corresponding to document directories within the document directory hierarchy.

A distributed collection of web-crawlers to gather information over a large portion of the cyberspace. These crawlers share the overall crawling through a cyberspace partition scheme. They also collaborate with each other through load balancing to maximally utilize the computing resources of each of the crawlers. The invention takes advantage of the hierarchical nature of the cyberspace namespace and uses the syntactic components of the URL structure as the main vehicle for dividing and assigning crawling workload to individual crawler. The partition scheme is completely distributed in which each crawler makes the partitioning decision based on its own crawling status and a globally replicated partition tree data structure.

A data structure, added to a modified form of the Blink-tree data structure, tracks delete states for nodes. The index delete state (DX) indicates whether it is safe to directly access an index node without re-traversing the B-tree. The DX state is maintained globally, outside of the tree structure. The data delete state (DD) indicates whether it is safe to post an index term for a new leaf node. A DD state is maintained in each level 1 node for its leaf nodes. Delete states indicate whether a specific node has not been deleted, or whether it may have been deleted. Delete states are used to remove the necessity for atomic node splits and chains of latches for deletes, while not requiring retraversal. This property of not requiring a retraversal is exploited to simplify the tree modification operations.

A virtual web-based computing platform combining a particular network database hierarchy, graphical user interface, and integrated suite of computational tools accessible on demand, by which users gain access to an integrated Virtual Workspace for organizing emails, contacts, bookmarks, tasks, documents, notes, and all other relevant information.

Embodiments provide a strategy for computing the motions of a mobile robot operating in an obstacle-laden environment without requiring prior knowledge of the distribution of obstacles in the environment or knowing the trajectory of a target tracked by the robot. Embodiments provide an algorithm that governs the motion of the observer robot based on measurements of the target's position and the location of obstacles in the environment. The algorithm computes a description of the geometric arrangement between the target and the observer's visibility region produced by the obstacles and computes a continuous control rule using this description. Embodiments employ an escape-path tree data structure to categorize the target's possible modes of escaping from the observer robot's sensors and use the escape-path tree to determine the target's shortest escape path.

Disclosed is a method for data synchronization in a web-based transmission device management system, in which managing data requiring synchronization between a web server and a client is constructed as a tree data structure, and a change flag for judging a data change is easily set. The web server increases a second event number by a certain degree whenever an event datagram is transmitted to the client, and the client judges whether or not the event datagram is lost by comparing the second event number and a first event number stored by the client whenever an event datagram is transmitted from the web server. If the event datagram is not lost, the client increases the first event number by a certain degree and performs data synchronization using the received event datagram. However, if the event datagram is lost, the client transmits every checksum of the leaf nodes in its tree data structure in one request datagram to the web server, and performs data synchronization by receiving changed data from the web server. Therefore, a loss of data is recognized promptly and precisely, and change of data on the web server also can be recognized promptly.

Transformations of digital records are used as lowest level inputs to a tree data structure having a root in a core system and having nodes computed as digital combinations of child node values. A combination of root values is published in a permanent medium. Signature vectors are associated with the digital records and have parameters that enable recomputation upward through the tree data structure to either a current root value or to the published value. Recomputation yields the same value only if a candidate digital record is an exact version of the original digital record included in the original computation of the value.

A method of predicting consumer response to given content. The process begins with the step of collecting a dataset of consumer response to the content, each data item including values for a selected set of segmentation variables related to past consumer behavior. The dataset contains at least twice the number of entries required to provide statistical validity. The process continues by constructing a classification tree structure using the dataset, in which the dataset is subdivided into learning and validation datasets of substantially equal size. Also, the criterion for each successive split is the lowest entropy of segmentation variables not employed to the point of such split. Each successive split of the learning dataset is performed only if that split produces child nodes statistically different from one another, and an identical split of the validation data set produces child nodes statistically similar to child nodes produced on the learning dataset. The system estimates consumer responses by first receiving a data item related to a new consumer, including values for the segmentation variables and then computing the likely response of the new consumer to the content, employing the classification tree data structure.

The program extracts and determines properties from the content data request issued by the client. The program searches the tree data structure with the determined properties in order to find an instruction format node, whose associated node selection condition matches the properties. Thus, the instruction data set returned to the client can be provided in a flexible manner.
