  • Patent number: 11010430
    Abstract: A user submits a query to a search system that produces a search results page having one or more segments and a plurality of URLs relevant to the query. Embodiments of the disclosure ensure cohesion between the URLs and the segments on the search results page by evaluating each segment relative to the URLs. A relevancy score is calculated for each segment based on the URLs. The relevancy score for each segment is compared to one or more thresholds. Depending on whether the relevancy score for each segment exceeds one or more thresholds, the segment can be eliminated from the search page, relocated on the search page, or left alone. Calculation of each relevancy score is based on information determined from a search log. A feedback loop can help improve the functioning of the suppression and/or relocation functions.

  • Publication number: 20170116638
    Abstract: A/B experiment validation implementations are presented that generally validate an A/B experiment prior to its release. One implementation involves employing multiple test execution engines to test a A/B experiment, and then aggregating the results. More particularly, a request to validate an A/B experiment is received from a requesting entity along with data pertaining to the A/B experiment. A category of the A/B experiment is then determined, and test execution engines applicable to the A/B experiment category are identified. For each test execution engine identified, the A/B experiment data is passed to the test execution engine, the test execution engine is requested to execute a test for the A/B experiment, and test results from the test of the A/B experiment are received. Once test results are received from the identified test execution engines, the test results are aggregated to produce a validation indicator.

  • Patent number: 8997235
    Abstract: Web applications, systems and services, which are prone to cyber-attacks, can utilize an adaptive fuzzing system and methodology to intelligently employ fuzzer technology to test web site pages for vulnerabilities. A breadth first search and minimal fuzzing testing is performed on identified pages of a web site looking for either a vulnerability or the potential for a vulnerability. Heuristics are gathered and/or generated on each tested web page to determine a vulnerability score for the page that is an indication of the page's potential for hosting a vulnerability. When a page is discovered with a vulnerability score that indicates the page has the potential for a vulnerability a depth first search and expanded fuzzing testing is performed on one or more branches of the web site that begin with the page with the potential vulnerability.

  • Patent number: 8972435
    Abstract: Query suggestions are generated based on a Breadth-First-Search having a configurable decaying radius. A computer system receives an initial set of semantically similar queries. The computer system expands the set to include related terms. The set of related terms is included in the initial set. The expansion process is repeated for each query or related term in the set. The radius may be reduced for each subsequent related term added to the query. The process may stop when the radius reaches a specified threshold, e.g., a predetermined number of queries or terms for the set is reached. The set includes the related terms and search queries. The set may be used for, among other things, suggesting related terms to a researcher, improving search engine performance, or selecting appropriate advertisements.

  • Patent number: 8700592
    Abstract: A web search system uses humans to rank the relevance of results returned for various sample search queries. The search results may be divided into groups allowing training and validation with the ranked results. Consistent guidelines for human evaluation allow consistent results across a number of people performing the ranking. After a machine learning categorization tool, such as MART, has been programmed and validated, it may be used to provide an absolute rank of relevance for documents returned, rather than a simple relative ranking, based, for example, on key word matches and click counts. Documents with lower relevance rankings may be excluded from consideration when developing related refinements, such as category and price sorting.
