Abstract: Similarity values are determined between pairs of stocks in a stock market. First, second and third optimum paths are determined which optimize respective functions of similarity values between first, second and third stocks, respectively, and a fourth stock. First, second and third concave regions are displayed to represent the first, second and third stocks, respectively. The third concave region is angularly adjacent the second concave region, but has a radial width that differs from a radial width of the second concave region. The first concave region is radially interposed between the second concave region and a region which represents the fourth stock to indicate that the first stock is in the second optimum path. The first concave region is radially interposed between the third concave region and the region to indicate that the first stock is in the third optimum path.

Abstract: A corresponding value is determined for each non-root node in a tree-defined path between a root node and a particular non-root node based on a weight W of the corresponding non-root node, a cumulative weight C1 of all descendants of the corresponding non-root node, and a cumulative weight C2 of all descendants of a parent of the corresponding non-root node. A product of all values corresponding to non-root nodes in the tree-defined path between the root node and the particular non-root node is determined. A region having an angular width and a radial width each based on the product is provided to represent the particular non-root node.

Abstract: An amount of interest to buy a stock in a stock market is determined based on a plurality of messages in which each of a plurality of brokers or dealers specifies an interest to buy the stock, a respective size of the stock to buy, and a respective price to buy the stock. The amount of interest to buy the stock in the stock market is visually represented in a user interface by a region approximately shaped as a circular annulus sector whose outer radius is based on the amount of interest to buy the stock. The outer radius is independent of a price change of the stock.

Abstract: A search expression is received. A first plurality of values is determined for a corresponding plurality of purchasable items. Each of the first plurality of values is based on a similarity between the search expression and its corresponding one of the purchasable items. A second plurality of values is determined for a corresponding plurality of pairs of the purchasable items. Each of the second plurality of values is based on a similarity between two purchasable items in a corresponding one of the pairs. A corresponding optimum path between the search expression and each of a subset of the purchasable items is determined based on at least one of the first plurality of similarity values and at least one of the second plurality of similarity values.
