International Classification:

G06N 5/02
G06F 17/21

US Classification:

706 48, 706 61

Abstract:

The invention includes methods and software tools for acquiring data from diverse sources, and structuring the data in a form that may be used to determine object equivalence. Practice of the invention includes one or more of the following tools: a data acquisition web agent creator, a web agent created by the web agent creator, an agent manager for deploying said web agent, and ontology-directed classifier, an ontology-directed extractor, and an ontology-directed matcher. The tools are example driven through a graphical user interface.

Abstract:

A user programmable deductive spreadsheet is implemented as an add-in to an existing mathematical spreadsheet program and allows the use of a logic programming language such as Prolog via a familiar spreadsheet interface. A syntax is provided whereby a set of multiple values can be stored in a cell and can be operated on recursively by an expression in another cell. Rows and columns can be given user defined names and cells can be referenced by row and column name. Cells can reference cells in other spreadsheets or can reference an entire spreadsheet in one cell. A cell expression can reference itself. Logical, arithmetic, and lifted operators are provided. Spreadsheets can be defined as a transformation of another spreadsheet. When no negative or aggregate operators are used in the cell expressions, the meaning of the spreadsheet is given in terms of least fixed points. Otherwise, the meaning is given in terms of perfect models.

Assignee:

Pitney Bowes - Stamford CT

International Classification:

G06F 900

US Classification:

380 23

Abstract:

A system for the metering of encrypted postage and similar indicia includes a device for printing such indicia and a device for reading such indicia. The printing is accomplished with a dot matrix printer driven by signals obtained by altering character generation signals with encryption signals. The interleaving is accomplished on a row-by-row basis by inserting delays from an encryption circuit into signals from a character generator circuit. The reading is accomplished by correlating received characters against a stored array of a symbols to determine the presence of a symbol, the extraction of coded data from character data of the received and identified character, and the comparison of the separated coded data with a reference code to determine the accuracy of the printed material. Thereby, forgery and alteration is inhibited. The coding is accomplished with the dot matrix format of the characters by displacing some of the dots slightly from the remainder so as to retain the general form of the character for recognition of the character while the displaced dots serve as the code for the encryption.
