A method and system organize and retrieve information using taxonomies, a document classifier, and an autocontextualizer. Documents (or other knowledge containers) in an organization and retrieval subsystem may be manually or automatically classified into taxonomies. Documents are transformed from clear text into a structured record. Automatically constructed indexes help identify when the structured record is an appropriate response to a query. An automatic term extractor creates a list of terms indicative of the documents' subject matter. A subject matter expert identifies the terms relevant to the taxonomies. A term analysis system assigns the relevant terms to one or more taxonomies, and a suitable algorithm is then used to determine the relatedness between each list of terms and its associated taxonomy. The system then clusters documents for each taxonomy in accordance with the weights ascribed to the terms in the taxonomy's list and a directed acyclic graph (DAG) structure is created.

System and method for implementing a knowledge management system

A method and system are disclosed for retrieving information through the use of a multi-stage interaction with a client to identify particular knowledge content associated with a knowledge map. The present invention is an application program running on a server accessed via the world-wide web or other data network using standard Internet protocols, a web browser and web server software. In addition to an automated portion, the present invention allows a human dialog designer to model the way the system elicits information, giving a human feel to the dialog and a better customer experience. In operation, users start a dialog by directing their web browser to a designated web page. This web page asks the user some initial questions that are then passed to a dialog engine. The dialog engine then applies its methods and algorithms to a knowledge map, using dialog control information\ and the user's responses to provide feedback to the user. The feedback may include follow-up questions, relevant documents, and instructions to the user (e.g., instructions to contact a human customer service representative). This dialog engine response is rendered as a web page and returned to the user's web browser. The user can then respond further to the follow-up questions he or she is presented, and the cycle repeats. The invention can be implemented so that it can interact with customers through a wide variety of communication channels including the Internet, wireless devices (e.g., telephone, pager, etc.), handheld devices such as a Personal Data Assistant (PDA), email, and via a telephone where the automated system is delivered using an interactive voice response (IVR) and/or speech-recognition system.

A method of retrieving documents using a search engine includes providing a reverse index including one or more keywords and a list of documents containing the one or more keywords, the reverse index further including a measure of confidence (MOC) value associated with the one or more keywords. One or more query terms are input into the search engine. The query terms are disambiguated and a MOC value is associated with each meaning of the disambiguated query term. A list of documents is retrieved containing the query terms wherein the documents are initially ranked based at least in part on the MOC values of the keywords and query terms. The list of documents may be re-ranked based at least in part on the semantic similarity of each document to the disambiguated query terms.

An integrated data mining and relational database management system is provided on a server. The data mining engine determines characteristics of relationships between input data values and an output data value that are obtained from a relational database (managed by the relational database management system). The integration allows direct conversion of data values from the relational database to data mining identifiers used for data mining operations by the data mining engine, and vice-versa. The integrated server also makes patterns uncovered during data mining (e.g., “understand” and “predict” information) available in virtual relational database tables that can be queried.

Techniques to improve query caching performance by efficiently selecting queries stored in a cache for evaluation and increasing the cache hit rate by allowing for inexact matches. A list of candidate queries stored in the cache that potentially could be used to answer a new query is first determined. This list may include all cached queries, cached queries containing exact matches for select list items, or cached queries containing exact and/or inexact matches. Each of at least one candidate query is then evaluated to determine whether or not there is a cache hit, which indicates that the candidate query could be used to answer the new query. The evaluation is performed using a set of rules that allows for inexact matches of aggregates, if any, in the new query. A query plan is generated for the new query based on a specific candidate query with a cache hit.

Detecting and processing cache hits for queries with aggregates

Methods and systems for performing cross store joins in a multi-tenant store are described. In one embodiment, such a method includes retrieving data from a multi-tenant database system having a relational data store and a non-relational data store, receiving a request specifying data to be retrieved from the multi-tenant database system, retrieving, based on the request, one or more locations of the data to be retrieved, generating a database query based on the request, in which the database query specifies a plurality of data elements to be retrieved, the plurality of data elements including one or more data elements residing within the non-relational data store and one or more other data elements residing within the relational data store, and executing the database query against the multi-tenant database system to retrieve the data.

Hybrid target indexes are employed for skewed data set domains. Such hybrid indexes contain multiple value representations within a given index. The representations can be optimized for particular keys in highly skewed data set domains. For example, a hybrid target index on customer states might employ a bitmap to represent the index value for a California key and also employ, in the same index, an uncompressed list of row-IDs to represent the index value for a Delaware key.

System and method for continuously adaptive indexes

The present invention is directed towards systems and methods for generating a compressed data file providing access to one or more selected portions of data contained within the data file. The file is partitioned into one or more chunks, a given chunk comprising a separate unit of data representing a subset of data from the file. The one or more chunks are compressed through use of a compression algorithm, and the one or more chunks are combined to form a compressed file. Metadata is also generated that indicates a chunk offset of a given chunk, thereby allowing direct parallel access to one or more given chunks. Similarly, legacy applications may ignore the chunk structure in the compressed file and access the file according to techniques know in the art, thereby preserving backwards compatibility with such legacy applications.
