Publication number: 20150134463Abstract: Techniques and mechanisms described herein facilitate the performance metric based placement of bids. According to various embodiments, a first threshold value for bid placement may be identified. The first threshold value may designate a first threshold performance metric level for advertising opportunity bid requests received during a designated time period. An estimated performance metric may be determined for a designated advertising opportunity bid request received during the designated time period. A bid placement message may be transmitted via a communications interface when the estimated performance metric is greater than the first threshold value. The bid request may identify the designated advertising opportunity bid request and a bid placement value.Type: ApplicationFiled: November 8, 2013Publication date: May 14, 2015Applicant: Turn Inc.Inventors: Ali Jalali, Ali Dasdan, Kuang-chih Lee

Patent number: 8880449Abstract: This disclosure describes systems and methods for identifying and correcting anomalies in web graphs. A web graph is transformed into a set of weighted features. The set of weighted features are then transformed into a signature via a SimHash algorithm. The signature is compared to the signature of one or more other web graphs in order to determine similarity between web graphs. Actions are then carried out to remove anomalous web graphs and modify parameters governing web mapping in order to decrease the likelihood of future anomalous web graphs being built.Type: GrantFiled: September 24, 2008Date of Patent: November 4, 2014Assignee: Yahoo! Inc.Inventors: Ali Dasdan, Panagiotis Papadimitriou

Publication number: 20140304086Abstract: A bid determination platform receives specifications for advertisements, each associated with a model configured to adjust a parameter value of a bid based on different combinations of user and/or media content characteristics associated with different advertisement requests. The platform also receives an advertisement request for placement of an advertisement on an advertisement space of a publisher's media content that has been requested by a user, and the advertisement request is associated with a set of user and media content profile data. For each of the advertisements, all or a subset of the set of user and/or media content profile data is input to each model so as to determine an associated parameter value. Bids for each advertisement are determined, with at least some bids being based on the associated parameter value. An optimum bid is sent with a location of its advertisement to the advertisement request sender.Type: ApplicationFiled: September 27, 2013Publication date: October 9, 2014Applicant: Turn Inc.Inventors: Ali Dasdan, Andrey Svirsky

Publication number: 20140226910Abstract: Techniques for identifying prohibited information within an image are described. For example, a machine accesses an image that depicts an item. The image may include prohibited information that is disallowed in accordance with a policy. The machine identifies the prohibited information within the image based on an analysis of the image. The machine initiates a response to the prohibited information based on the identifying of the prohibited information within the image.Type: ApplicationFiled: April 17, 2014Publication date: August 14, 2014Applicant: eBay Inc.Inventors: Sanjay Pundlkrao Ghatare, Ali Dasdan, Naren Chittar

Publication number: 20140164146Abstract: Image-based features may be significantly correlated with click-through rates of images that depict a product, which may provide a more formal basis for the informal notion that good quality images will result in better click-through rates, as compared to poor quality images. Accordingly, an image assessment machine is configured to analyze image-based features to improve click-through rates for shopping search applications (e.g., a product search engine). Moreover, the image assessment machine may rank search results based on image quality factors and may notify sellers about low quality images. This may have the effect of improving the brand value for an online shopping website and accordingly have a positive long-term impact on the online shopping website.Type: ApplicationFiled: February 13, 2014Publication date: June 12, 2014Applicant: EBAY INC.Inventors: Anjan Goswami, Naren Chittar, Ali Dasdan, Sanjay Pundlkrao Ghatare, Sandip Namdeo Gaikwad, Sung Hwan Chung

Patent number: 8750557Abstract: A metadata extraction machine accesses an image that depicts an item and identifies an attribute of the item and a descriptor that specifies a value for the identified attribute. The machine identifies the attribute and the descriptor based on an analysis of the accessed image that includes distinguishing a foreground portion of the image from a background portion of the image. Distinguishing a foreground portion from the background portion may include segmenting the image to identify the foreground and background portions. Some or all of the analysis may be performed by the machine. The machine then stores the identified descriptor of the item as metadata of the item.Type: GrantFiled: February 15, 2011Date of Patent: June 10, 2014Assignee: eBay Inc.Inventors: Sanjay Pundlkrao Ghatare, Ali Dasdan, Naren Chittar

Patent number: 8726290Abstract: The subject matter disclosed herein relates to a system and/or method for allocating data among reduce processes. In a particular implementation, a map process may be executed to provide intermediate data associating key/value pairs with input data. Intermediate data may be allocated among a plurality of reduce processes. At least a portion of intermediate data initially allocated to one or more of said reduce processes may be re-allocated based, at least in part, on a load factor associated with one or more reduce processes.Type: GrantFiled: June 12, 2008Date of Patent: May 13, 2014Assignee: Yahoo!

Publication number: 20140046754Abstract: Embodiments of the invention present an approach to conversion rate estimation which relies on using past performance observations along user, publisher, and advertiser data hierarchies. More specifically, embodiments of the invention model the conversion event at different select hierarchical levels with separate binomial distributions and estimate the distribution parameters individually. It is shown how to combine these individual estimators using logistic regression to identify conversion events accurately. Embodiments of the invention can also handle many practical issues, such as data imbalance, missing data, and output probability calibration, which render this estimation problem more difficult for a real-world implementation of the approach.Type: ApplicationFiled: August 13, 2012Publication date: February 13, 2014Inventors: Kuang-Chih LEE, Burkay Birant ORTEN, Ali DASDAN, Wentong LI

Patent number: 8417657Abstract: This disclosure describes systems and methods for identifying and correcting anomalies in web graphs. A web graph is transformed into a sequence of tokens via a walk algorithm. The sequence is fingerprinted to form a set of shingles. The singles are compared to shingles for other web graphs in order to determine similarity between web graphs. Actions are then carried out to remove anomalous web graphs and modify parameters governing web mapping in order to decrease the likelihood of future anomalous web graphs being built.Type: GrantFiled: May 2, 2011Date of Patent: April 9, 2013Assignee: Yahoo!

Patent number: 8190610Abstract: An input data set is treated as a plurality of grouped sets of key/value pairs, which enhances the utility of the MapReduce programming methodology. By utilizing such a grouping, map processing can be carried out independently on two or more related but possibly heterogeneous datasets (e.g., related by being characterized by a common primary key). The intermediate results of the map processing (key/value pairs) for a particular key can be processed together in a single reduce function by applying a different iterator to intermediate values for each group. Different iterators can be arranged inside reduce functions in ways however desired.Type: GrantFiled: October 5, 2006Date of Patent: May 29, 2012Assignee: Yahoo!
