20100306213 | Merging Search Results - Merging search results is required, for example, where an information retrieval system issues a query to multiple sources and obtains multiple results lists. In an embodiment a search engine at an Enterprise domain sends a query to the Enterprise search engine and also to a public Internet search engine. In embodiments, results lists obtained from different sources are merged using a merging model which is learnt using a machine learning process and updates when click-through data is observed for example. In examples, user information available in the Enterprise domain is used to influence the merging process to improve the relevance of results. In some examples, the user information is used for query modification. In an embodiment a user is able to impersonate a user of a specified group in order to promote particular results. | 12-02-2010 |
20110179017 | DETECTING SPIKING QUERIES - Methods, systems, and media are provided for identifying and clustering queries that are rising in popularity. Resultant clustered queries can be compared to other stored queries using textual and temporal correlations. Fresh indices containing information and results from recently crawled content sources are searched to obtain the most recent query activity. Historical indices are also searched to obtain temporally correlated information and results that match the clustered query stream. A weighted average acceleration of a spike can be calculated to distinguish between a legitimate spike and a non-legitimate spike. Legitimate clusters are combined with other stored clusters and presented as grouped content results to a user output device. | 07-21-2011 |
20110218946 | PRESENTING CONTENT ITEMS USING TOPICAL RELEVANCE AND TRENDING POPULARITY - A user may request a presentation of a content item set, such as a social network comprising a set of status messages or an image database comprising a set of images. However, the volume and diversity of content items of the content item set may reduce the interest of the user in the presented content items. The potential interest of the user in the presented content items may be improved by selecting content items that are associated with one or more topics of potential interest to the user, and having a positive trending popularity among users of the content item set. Moreover, the interaction of the user with a presented content item may be monitored and used to determine the interest of the user in the topics associated with the presented content item and the popularity of the content item. | 09-08-2011 |
20110307483 | ENTITY DETECTION AND EXTRACTION FOR ENTITY CARDS - A system and method are provided for detecting entity information contained within search results. The detected entity information can be used to determine a category of entity as well as a specific entity within the search results. Entity information can be extracted from the documents associated with the search results. This information can be used as part of the information for an entity card, which can be displayed to a user in conjunction with and/or in place of the search results. | 12-15-2011 |
20130138638 | TEMPORAL VISUALIZATION OF QUERY RESULTS - One or more techniques and/or systems are disclosed for constructing a temporal visualization of query results. That is, query results associated with temporal information, such as timestamps, may be used to create a temporal distribution (e.g., query results comprising images and image capture dates, web pages and web page creation dates, etc.). The temporal distribution may comprise a distribution of the query results over time (e.g., query results may be sorted and/or grouped based upon dates specified by the timestamps). A temporal visualization of the query results may be constructed using the temporal distribution. For example, query results may be assigned to date slots within the temporal visualization. The temporal visualization may illustrate a substantial number of query results (e.g., thousands) that may otherwise not be visually presentable at once. Zoom commands and/or hover commands may be processed to provide finer and/or coarser granularity of the query results. | 05-30-2013 |
20130246412 | RANKING SEARCH RESULTS USING RESULT REPETITION - Ranking search results using result repetition is described. In an embodiment, a set of results generated by a search engine is ranked or re-ranked based on whether any of the results were included in previous sets of results generated in response to earlier queries by the same user in one or more searching sessions. User behavior data, such as whether a user clicks on a result, skips a result or misses a result, is stored in real-time and the stored data is used in performing the ranking. In various examples, the ranking is performed using a machine-learning algorithm and various parameters, such as whether a result in a current set of results has previously been clicked, skipped or missed in the same session, are generated based on the user behavior data for the current session and input to the machine-learning algorithm. | 09-19-2013 |
20150213360 | CROWDSOURCING SYSTEM WITH COMMUNITY LEARNING - Crowdsourcing systems with machine learning are described, for example, to aggregate answers to a crowdsourced task in a manner achieving good accuracy even where observed data about past behavior of crowd members is sparse. In various examples a machine learning system jointly learns variables describing characteristics of both individual crowd workers and communities of the workers. In various examples, the machine learning system learns aggregated labels. In examples learnt variables describing characteristics of an individual crowd worker are related, by addition of noise, to learnt variables describing characteristics of a community of which the individual is a member. In examples the crowdsourcing system uses the learnt variables describing characteristics of individual workers and of communities of workers for any one or more of: active learning, targeted training of workers, targeted issuance of tasks, calculating and issuing rewards. | 07-30-2015 |
20150363485 | LEARNING AND USING CONTEXTUAL CONTENT RETRIEVAL RULES FOR QUERY DISAMBIGUATION - Various technologies related to generating and applying content retrieval rules are described herein. A content retrieval rule maps a combination of a query and a context to one of a query reformulation or content. The content retrieval rule is learned from search logs of a search engine, and is applied when the query having the context is received at the search engine. | 12-17-2015 |
20160034471 | ENTITY DETECTION AND EXTRACTION FOR ENTITY CARDS - A system and method are provided for detecting entity information contained within search results. The detected entity information can be used to determine a category of entity as well as a specific entity within the search results. Entity information can be extracted from the documents associated with the search results. This information can be used as part of the information for an entity card, which can be displayed to a user in conjunction with and/or in place of the search results. | 02-04-2016 |
