Abstract: In various example embodiments, systems and methods for providing category aspect information by mining historical data is provided. In example embodiments, a table comprising joined data is accessed. The table includes historical data that comprises user behavior data based on actions performed with past queries by users, data describing publication, and a determined category for each publication. Demand scores based on the joined data are determined. The determined demand scores are used to determine most relevant aspect name and aspect value pairs for a category. Publications having at least one of the most relevant aspect name and aspect value pairs are displayed visually distinguished from less relevant publications that exclude the most relevant aspect name and aspect value pairs.

Abstract: A system receives images of objects. The system identifies a category for each of the objects, and extracts features from the images. The features relate to a quality of the image. The features of the images are stored in a database according to the category of each object, such that each set of features is associated with its corresponding image. The system displays the images on a network-based publication system, and receives data relating to the displayed images. The data is analyzed, and the images are ranked as a function of the analysis. The system redisplays the images on the network-based publication system as a function of the ranking of the images.

Abstract: Systems and methods for providing category aspect information by mining historical data is provided. A table comprising joined data is accessed. The table includes historical data that comprises user behavior data based on actions performed with past queries by users listing data that includes aspect data for each listing and a determined category for each listing. Demand scores based on the joined data are determined. The determined demand scores are used to determine at least one relevant aspect name for a category. A message is transmitted for display on a device of the user that indicates the at least one most relevant aspect name for the category and suggests the user provide an aspect value that corresponds to the at least one most relevant aspect name to be included in a new listing.

Abstract: In an example embodiment, a pseudo product group for an item to be listed in an online marketplace having unstructured data is determined. Then, a fair market price for the item is determined using past data from listings in the pseudo product group. The fair market price may be used as a reference price in a curve of price elasticity versus price to obtain a price elasticity value. A price range may then be recommended to a user for the listing based upon the fair market price and the price elasticity value.

Abstract: A system and method of determining the level of diversity for a search query are described. Distances between leaf categories in a hierarchical category tree are determined using co-click counts between the leaf categories for a query. Coordinate representations of the leaf categories are determined using the distances between the leaf categories. A diversity score for the query is determined using the coordinate representations. The diversity score represents a degree of variability in what different users find relevant to the query. In some embodiments, determining distances between leaf categories comprises determining the distances using a normalization of the co-click counts that uses co-impression counts between the leaf categories for the query. In some embodiments, a manifold learning algorithm is used to determine the coordinate representations. In some embodiments, multi-dimensional scaling is used to determine the coordinate representations.
