The subject matter disclosed herein relates to processing information regarding events. In one particular example, a stabbing query may be formulated in response to an event. One or more sets are associated with and/or mapped to nodes of a tree.

A query optimization technique that determines whether a query includes a self join that is transitively derived through table expressions having UNION operators. If so, the query is simplified to eliminate the table expressions and to reduce the query to an equivalent query over tables.

A method for publishing relational data as XML by translating XML queries into queries against an relational database. Conversion of the relational database into an XML database is not required. Each relational table is mapped to a virtual XML document, and XML queries are issued over these virtual documents. An XML query is parsed and transformed into a language-neutral intermediate representation, which is a sequence of operations describing how the output document is derived from the underlying relational tables. The intermediate representation is then translated into an SQL query over the underlying relational tables and into instructions for a tagger. The SQL query is executed, and the SQL query results are then fed into the tagger, which follows tagger instructions to generate the marked up output.

Techniques are provided relating to conducting bucket testing in connection with guaranteed delivery online advertising associated with an online advertising marketplace. Techniques are provided in which advertising supply, demand, or both are partitioned into buckets. Operating policies are established for each of the buckets, in which the operating policies for each of the buckets differ. Following serving of advertisements in accordance with the operating policies, difference is measured in at least one outcome, between buckets.

A method for pricing a contract for serving advertisements in an online display advertising environment comprising receiving a subject contract, the subject contract having at a target predicate for matching to a user visit, then forecasting, using a computer-based forecasting module, a set of user visits eligible to be served to the subject contract, wherein eligibility is based on matching the target predicate to a user visit (which user visit may be associated with an event predicate). Having a set of forecasted (matching) user visits, the method proceeds to select a set of eligible historical contracts that would be eligible to be served to the forecasted user visits. Finally, having a set of eligible historical contracts that would be eligible to be served to the target predicate, a curve fitting technique yields a price for the subject contract that minimizes the error in the price relative to expected user visits.
摘要:
A system and method for bidding on advertisements. The system includes a query engine and an advertisement engine. The query engine receives a query from the user. The query engine analyzes the query to determine a query intent that is matched to a predetermined domain. A translated query is generated including the domain type. Once a domain is selected, the query may be further analyzed to determine generic domain information. The domain and associated information may then be matched to a list of advertisements. The advertisement may be assigned a score based on a bid price and a quality of the advertisement.

A system, method, and computer program product for processing XML queries over relational data and meta-data using a relational database system. The invention runs a query to generate a view definition, so a regular query processor can handle queries on a mix of data and meta-data. Names of desired tables are data-dependent, so the invention represents a default XML view as an XML query over the relational tables, gets the table names and table data by recursively invoking the query processor (first by querying the catalog table, and then querying base data according to a new construct). The invention thus processes queries over table names in addition to table values.
