A method of operating a computerized document search system where information is matched against a database containing documents in response to user queries includes receiving a query identifying a source document that has information content related to the documents within the database. Important words within the source document are detected automatically, where at least one of the important words has been processed using at least two dictionary functions consisting of Derived Words, Acronym, Word Capitalization, and Hyphenation. An importance value is generated for important words in a processed document using a WordRatio and at least one of a selected set of values. A score is generated for a processed document based partly on the importance value of at least one important word in that document. A document list is created for identifying documents that are related to a source document.

In an automated leads-and-bids matching system, bid profiles are defined to describe desires of lead buyers. Received leads are matched to active ones of the bid profiles whose specifications the leads substantially match. Lead segmentation data is captured on-the-fly for example by inducing potential consumers to navigate their way through tree-organized web sites that categorize the consumers according to their geographic location, income / revenue range, class of products desired and / or other attributes. Live voice or other telecommunication connections to the pre-classified consumers are coupled to corresponding, pre-classified telecommunication nodes of a call processing system. The call processing system deduces the segmentation data of the consumers from the identities of the pre-classified nodes through which their connections pass. The deduced segmentation data is passed to an automated matching system or auctioning subsystem that finds the highest bids for each given lead. A quality rating database rates the quality of leads provided by different sellers. A price discounting engine discounts the amount paid to sellers who are hot-rated as sources of inferior leads.

Systematic use of infrared imaging characterizes marks made on items and identifies the particular marking tool with better accuracy than use of visual imaging. Infrared imaging performed in total darkness eliminates shadows, glint, and other lighting variations and artifacts associated with visible imaging. Although normally used to obtain temperature measurements, details in IR imagery result from emissivity variations as well as thermal variations. Disturbing an item's surface texture creates an emissivity difference producing local changes in the infrared image. Identification is most accurate when IR images of unknown marks are compared to IR images of marks made by known tools. However, infrared analysis offers improvements even when only visual reference images are available. Comparing simultaneous infrared and visual images of an unknown item, such as bullet or shell casing, can detect illumination-induced artifacts in the visual image prior to searching the visual database, thereby reducing potential erroneous matches. Computer numerically controlled positioning of the toolmark relative to imaging sensors which use fixed focus optics with shallow depth of focus, varying focus distance and orientation systematically to construct a sequence of images, maximizes reliability of resulting images and their comparisons.

This invention introduces a new concept called virtual construct intervals (VCI), where each predicate interval is decomposed into one or more of these construct intervals. These VCIs strictly cover the predicate interval. Namely, every attribute value covered by the predicate interval is also covered by at least one of the decomposed VCIs, and vice versa. Each construct interval has a unique ID or interval coordinate and a set of endpoints. A construct interval is considered activated when a predicate interval using it in its decomposition is added to the system. The predicate ID is then inserted into the ID lists associated with the decomposed VCIs. To facilitate fast search, a bitmap vector is used to indicate the activation of VCIs that cover an event value. The challenge is to find an appropriate set of construct intervals to make predicate decomposition simple and, more importantly, to build efficient bitmap indexes. Because each construct interval covers only a small range of attribute values, the invention also uses bitmap clipping to cut unnecessary bitmap storage. To facilitate bitmap clipping, the invention introduce the covering segment concept. Bit positions outside a covering segment are pruned.
