A data-driven, hierarchical information search and navigation system and method enable search and navigation of sets of documents or other materials by certain common attributes that characterize the materials. The invention includes several aspects of a data-driven, hierarchical search and navigation system that employs this search and navigation mode. The search and navigation system of the present invention includes features of an navigation interface, a search interface, a knowledge base and a taxonomy definition process and a classification process for generating the knowledge base, a graph-based navigable data structure and method for generating the data structure, World Wide Web-based applications of the system, and methods of implementing the system. Users are able to search or browse a particular collection of documents by selecting desired values for the attributes or by searching the attribute-value pairs. A data-driven, hierarchical information search and navigation system and method enable this navigation mode by associating terms with the materials, defining a set of hierarchical relationships among the terms, providing a guided navigation mechanism based on the relationship between the terms, and providing a search mechanism that can respond to free-text queries with single-term or multi-term interpretations. In another aspect of the invention, implementations of the invention may be scalable through parallel or distributed computation.

Systems and methods for dynamically load-balancing clients across available servers without the need for a load balancer in front of a network are provided. Exemplary methods assign servers to clients in wireless and wireline networks based on server load. Methods and systems for using the authentication, authorization, and accounting (AAA) protocols to load-balance network servers are provided. The load-balancing systems and methods further include using the Diameter AAA protocol routing attribute value pairs (AVPs) to implement bootstrap functionality and load balancing. Methods and systems using the Diameter protocol to manage client assignments are disclosed. Methods and systems for dynamically load-balancing clients across available servers using an AAA protocol are further described. Methods and systems to redirect clients to available servers with the least load are disclosed.

A method is disclosed for modifying the results of a search performed in a collection of items by a search and navigation system. The method includes receiving a query from a user interface and determining a navigation state, defined by expressions of attribute-value pairs, based on the received query. The user interface accepts both selecting and deselecting of any of the attribute-value pairs in an expression corresponding to a navigation state to obtain an expression corresponding to a different navigation state, and each selection and deselection forms a new query. The method further includes retrieving, from the collection, items associated with the navigation state to form a set of unmodified search results, the set of unmodified search results having an arrangement for presentation to the user. A rule filter that includes a metadata expression is applied to a set of rules, each rule having a trigger, an action, and metadata. The application of the rule filter to the set of rules includes evaluating the metadata expression of the rule filter based on the metadata of each rule and passing rules for which the metadata expression of the rule filter evaluates as logical true. The trigger of each rule passed by the rule filter is evaluated, and the action of each rule for which the trigger of the rule evaluates as logical true is executed to modify the unmodified search results to form modified search results.

A method and system for retrieving and normalizing product information are described. The system retrieves product information from sources that are accessed over a network. Next, the system creates markup language based on the product information. The markup language includes a first attribute-value pair that includes a first attribute and a first value. Next, the system normalizes the markup language by translating the first attribute to a second attribute responsive to an identification of the first attribute in a list that includes a plurality of attributes that are associated with a first product and the second attribute. The second attribute is a canonical representation of the plurality of attributes respectively.

One or more classification algorithms are applied to at least one natural language document in order to extract both attributes and values of a given product. Supervised classification algorithms, semi-supervised classification algorithms, unsupervised classification algorithms or combinations of such classification algorithms may be employed for this purpose. The at least one natural language document may be obtained via a public communication network. Two or more attributes (or two or more values) thus identified may be merged to form one or more attribute phrases or value phrases. Once attributes and values have been extracted in this manner, association or linking operations may be performed to establish attribute-value pairs that are descriptive of the product. In a presently preferred embodiment, an (unsupervised) algorithm is used to generate seed attributes and values which can then support a supervised or semi-supervised classification algorithm.

Mechanisms for developing Diameter applications are provided. The mechanisms extend the application server servlet model to support Diameter applications. A “base protocol” servlet is provided that handles the basic Diameter protocol functionality. Base application servlets are provided for each Diameter interface (for example, an “Sh” base servlet for the IMS “Sh” interface). These servlets are base classes for application code. The base application servlets implement additional semantics on top of the base protocol servlet to support additional attribute-value pair semantics. With the system and method, Diameter servlets share the same ServletContext as HTTP and SIP servlets. This mechanism facilitates communication between the various application entities and facilitates generation of converged applications.

There is disclosed a method for charging for services in a communication system supporting a Diameter IP protocol, comprising defining at least one attribute value pair to define sponsorship information.

A device for generating semantic folder annotations is provided. The device includes a semantic folder editor which enables a user to create attribute-value pairs corresponding to a semantic folder(s). The device is capable of downloading ontolog(ies) and associated data from an ontology server which may be utilized to determine relationships between the attribute-value pairs created by the user. The device includes an annotations generator which specifies the semantic folder descriptions of the semantic folders based on attribute-value relationships determined by the ontolog(ies). The device is capable of allowing a user to insert an object(s) into a semantic folder(s) and the annotations generator assigns all attribute-value pairs corresponding to the semantic folder to the object(s). The annotations assigned to object(s) may be stored in a semantic triple store. The device further includes a search engine which may be employed by a user to search semantic folders to locate an object(s).

A method and system for communication between server-less computing devices or clients in computers communicating over networks, such as the World Wide Web (WWW) using stateless protocols, e.g., HTTP. In this scheme there are two classes of clients which can operate independently or can be combined in computer communicating over the network: a) Clients that issue commands and request status or data, and b) clients which function as service brokers for provide services and processing commands, updating status and providing specific data. Based on the description of the latter client device it would resemble a server device but without accessible TCP / IP ports. Each service providing device is authenticated, retains a unique identity and establishes a soft state with the globally accessible server or servers. All devices and clients can compile and process a globally common command language established between all communicating network clients. The central server includes a CGI processing program and a database to retain client specific information. The server database represents a collection of queues, each having a client unique identifiable status, pending commands and / or data components. In this scheme commands and signaling transmitted between the servers and clients utilize standard HTTP protocol semantics and HTML or standard markup language syntax. Clients encapsulate or embed information as parameters passed to HTTP CGI as a set of standard HTTP conversations. A CGI processing program converts, parses or processes each conversation and passes arguments with or without data to queues. Each conversation is includes a client identification key(s) and commands which are structured as attribute-value pair tuples. The service-handler client connects to the central server and accesses the client queue on the central server to check for any pending commands or update their status in either synchronous or asynchronous manner. The synchronous server access scheme is regulated temporally by either deterministic clocking on server response or by a server based adaptive algorithm which can monitor network and client activities and optimize client access patterns.
