20100262596 | METHODS AND SYSTEMS FOR DERIVING DEMAND METRICS USED IN ORDERING ITEM LISTINGS PRESENTED IN A SEARCH RESULTS PAGE - Methods and systems for using a half-life formula for deriving demand metrics used in ordering item listings, when presenting those item listings in a search results page, are described. In some embodiments, a demand metric for an item listing is derived by monitoring events associated with item listings, such as, keeping a count of the number of search impressions an item listing receives. A half-life formula is used to ensure that events occurring earlier in time contribute less to the demand metric than more recently occurring events. The demand metric are used to order the item listings, when the item listings are being presented in a search results page. | 10-14-2010 |

20100262601 | METHODS AND SYSTEMS FOR ASSESSING THE QUALITY OF AN ITEM LISTING - Methods and systems for assessing the quality of an item listing are described. In an example embodiment, a listing quality score for an item listing is derived as a weighted sum of first and second parts. The first part represents a predicted score based on a comparison of item attributes for the item listing that are known at listing time, with item attributes of similar item listings that have historical data available for assessing their actual performance. The second part is based on one or more observed demand metrics representing actual historical performance of the item listing. The weighting factor is derived, such that over time, the emphasis shifts from the predicted to the observed score. | 10-14-2010 |
20100262602 | METHODS AND SYSTEMS FOR DERIVING A SCORE WITH WHICH ITEM LISTINGS ARE ORDERED WHEN PRESENTED IN SEARCH RESULTS - Methods and systems for analyzing, ordering and presenting item listings are described. In one example embodiment, a search query is processed to identify item listings satisfying the search query. Then, for each item listing that satisfies the search query, a ranking score is derived and assigned to the item listing. The ranking score is based in part on a relevance score, a listing quality score and a business rules score (or, adjustment factor). Finally, the item listings are ordered, based on their corresponding ranking score, and presented in order in a search results page. | 10-14-2010 |

The data engine module processes the API commands to identify and communicate relevant listing performance data that is used by a listing performance algorithm to assign a listing performance score to item listings satisfying a search request. The listing performance data provides sellers who have items listed for sale an insight as to how their item listings are performing in comparison to other item listings. | 03-31-2011 |
20110235902 | PRE-COMPUTING DIGESTS FOR IMAGE SIMILARITY SEARCHING OF IMAGE-BASED LISTINGS IN A NETWORK-BASED PUBLICATION SYSTEM - A system and method, which may be an offline method, extracts relevant image features about listing items in a network-based publication system for enabling image similarity searching of such listing items. When a seller lists an item, an image of the item is uploaded and may be sent to a picture processing service, which generates several digests. The digests are compressed data structures each representing a particular image feature such as edge, color, texture, or words. These digests are then stored in a search database, where the digests can be used to retrieve listings by image similarity at scale. A similar process can be performed for a query listing for searching the search database for items similar to the query listing. | 09-29-2011 |
20110238659 | TWO-PASS SEARCHING FOR IMAGE SIMILARITY OF DIGESTS OF IMAGE-BASED LISTINGS IN A NETWORK-BASED PUBLICATION SYSTEM - Using a processor, receiving, a query including a query image. A database is searched for a set of images similar to the query image, using a two-pass search. The results of the searching are then provided, the results including image members of the set of images similar to the query image. The first pass may be performed using a TF-IDF algorithm and the second pass ranks a predetermined number of results from the first pass by a best match algorithm or other type of algorithm. The type of second pass algorithm may be selectable by a user. If an end signal is not detected, a further two-pass search may be made based on a subsequent query having a subsequent query image. The subsequent query image may one of the results of the previous two pass search. A subsequent query image may change from an image of a product of a first product category to an image of a product of a second product category. | 09-29-2011 |
20110295716 | METHOD, MEDIUM, AND SYSTEM FOR ADJUSTING PRODUCT RANKING SCORES BASED ON AN ADJUSTMENT FACTOR - Methods and systems for evaluating business rules for the purpose of promoting or demoting an item listing are presented. Consistent with an example embodiment, a conditional statement of a business rule that includes one or more expressions involving an item attribute and/or a seller attribute for an item listing is evaluated. If the conditional statement evaluates true, an adjustment factor set forth in the business rule is applied to a ranking score assigned to the item listing. The item listing is then presented in a search results page in a position relative to other item listings based upon the adjusted ranking score. | 12-01-2011 |
20110314031 | PRODUCT CATEGORY OPTIMIZATION FOR IMAGE SIMILARITY SEARCHING OF IMAGE-BASED LISTINGS IN A NETWORK-BASED PUBLICATION SYSTEM - A weighted combination of attributes including but not limited to color, shape, pattern, brand, style, size, and material may be used to rank items when searching for similar items of a given category on an ecommerce system website. The weights on each attribute may be optimized by using feedback from users, the feedback indicating the importance of each attribute to a purchaser when searching for similar items of various categories. Alternatively, click-through patterns from the ecommerce system website can be mined and used to optimize the importance of each attribute to users by item category. The optimum attribute weights for that items category are used to rank the results in a search for similar items in that category. | 12-22-2011 |
20120041846 | SELLER CONVERSION FACTOR TO RANKING SCORE FOR PRESENTED ITEM LISTINGS - Various embodiments include a method and system for a seller conversion factor to ranking score for presented item listings. In an online marketplace with sellers and item listings, a first sum may be calculated by identifying a first set of item listings associated with the seller. A second sum may also be calculated by identifying a second set of item listings, where the second set is a subset of the first set and are successful item listings. Further, a conversion factor may be calculated from the first and second sums by dividing the second sum by the first sum. The conversion factor may then be used as a component in an item listing quality score for a third set of item listings associated with the seller. | 02-16-2012 |
