Abstract: A system and method of identifying suspicious item-related features are disclosed. In some embodiments, a new item listing is received. The item listing may correspond to a request to list an item for sale on an e-commerce website. Item-related data for the item listing may be extracted. The item-related data can be used by a model to classify the new item listing. The model may be trained on data comprising identifications of which item listings in the sample of item listings are suspicious and identifications of which item listings in the sample of item listings are not suspicious may be received.

Abstract: Example embodiments described herein disclose systems and methods for near-identical multi-faceted entity identification within search results from an online marketplace. The online marketplace may be or include a group of one or more server machines configured to provide one or more online marketplace services, including the near-identical multi-faceted entity identification system. A user device may accordingly request and receive, from the online marketplace, a set of item listings based on submitted search criteria. The online marketplace may then access the set of item listings and identify one or more similar item listings among the set of item listings in order to demote a ranking of the similar item listings within the set.

Abstract: A user may submit a search query to a search engine. The search engine may process the search query and generate a set of results. Each of the items searched by the search engine may have been pre-assigned to a category in a category tree. Previous interactions by other users with the items after similar queries may have been recorded. The search engine may identify categories based on the distribution of the interacted-with results among the categories. The category tree may be analyzed at different levels, based on the entropy observed at each level. A level with low entropy may be chosen, and categories at that level used to constrain the query.

Abstract translation: 用户可以向搜索引擎提交搜索查询。 搜索引擎可以处理搜索查询并生成一组结果。 搜索引擎搜索的每个项目可能已被预分配给类别树中的类别。 其他用户在类似查询之后的以前交互可能已被记录。 搜索引擎可以基于与类别之间的交互的结果的分布来识别类别。 可以基于在每个级别观察到的熵来分类不同级别的类别树。 可以选择具有低熵的级别，并且该级别的类别用于约束查询。
