Abstract: Improved data content determination techniques are disclosed for use in accordance with information-seeking systems. For example, in one illustrative aspect of the invention, a technique for determining data content for a response to a query comprises obtaining a user query, and dynamically determining data content suitable for generating a response to the query, wherein data content determination is modeled as an optimization operation which attempts to balance context-based selection constraints. Further, the step of dynamically determining data content may further comprise modeling the context-based selection constraints as feature-based metrics. The feature-based metrics may be formulated using contextual information. Still further, the step of dynamically determining data content may further comprise performing the optimization operation such that one or more desirability metrics are maximized and one or more cost metrics are minimized, thus balancing the various constraints.

Abstract: In a system that switches multiple database servers to separate computers, a switching order of the database servers is variably changed and set. In the system that allows an executive system computer and a standby system computer having the database servers to share a database respectively, the system is switched from the database server of the executive system computer to the database server of the standby system computer.

Abstract: An apparatus, circuit, and method are provided herein for locating and extracting a plurality of matching entries from one or more databases stored within a Content Addressable Memory (CAM) device. The apparatus, circuit, and method may locate the plurality of matching entries by comparing variations of a single search key to the entire database of entries. In other words, a number of bits may be stored within each of the database entries as a descriptor field. When searching for a particular entry or entries, a corresponding descriptor field included within (or appended to) the search key may be modified, after at least one matching entry is found, for locating and extracting additional entries matching the original search key. Use of the descriptor field, therefore, enables the circuit and method to locate and extract a potentially unlimited number of entries matching the original search key.

Abstract: Systems and methods for automatically updating queries on a data store, such as a personal content database (PCDB), are provided. A query engine runs queries against two indexes: a first index that represents a previous state of documents and a second index that represents a current state of documents. The query is run twice and a delta analysis is performed, i.e., a determination is made as to which documents have changed in some respect from the previous state to the current state, and a view or a count associated with at least one query changes in accordance with the delta analysis. Transactions may be batched dynamically by a transaction manager until an optimal number of documents have changed or a certain amount of time has passed prior to re-running the query and performing the delta analysis.
