First-order logic—also known as predicate logic, quantificational logic, and first-order predicate calculus—is a collection of formal systems used in mathematics, philosophy, linguistics, and computer science. First-order logic uses quantified variables over non-logical objects and allows the use of sentences that contain variables, so that rather than propositions such as Socrates is a man one can have expressions in the form "there exists x such that x is Socrates and x is a man" and there exists is a quantifier while x is a variable. This distinguishes it from propositional logic, which does not use quantifiers or relations; in this sense, propositional logic is the foundation of first-order logic.

ActiveUS20060048044A1Improve welfareText processingSpecial data processing applicationsFirst-order logicTheoretical computer science
A computerized spreadsheet system includes a set of cells and a separate set of logical constraints on the values of cells. The constraints may be many-to-many relationships that permit omni-directional propagation of values between cells. The constraints may be expressed in a language encompassing first-order logic. Cells are dynamically reclassified as base cells or computed cells as a user specifies values for cells. Non-explosive consequences of the base cell values are computed and displayed in computed cells, even when the values in the base cells are inconsistent with the constraints. The spreadsheet system may also include an auto-complete feature that automatically fills in empty cells with values consistent with the logical constraints and an auto-deconflict feature that automatically changes values in cells to reduce conflicts with the logical constraints.

Automated anomaly detection
ActiveUS7627543B2Avoid overfitting noisy dataError detection/correctionDigital computer detailsData setNoisy data
A method of anomaly detection applicable to telecommunications or retail fraud or software vulnerabilities uses inductive logic programming to develop anomaly characterization rules from relevant background knowledge and a training data set, which includes positive anomaly samples of data covered by rules. Data samples include 1 or 0 indicating association or otherwise with anomalies. An anomaly is detected by a rule having condition set which the anomaly fu,lfils. Rules are developed by addition of conditions and unification of variables, and are filtered to remove duplicates, equivalents, symmetric rules and unnecessary conditions. Overfitting of noisy data is avoided by an encoding cost criterion. Termination of rule construction involves criteria of rule length, absence of negative examples, rule significance and accuracy, and absence of recent refinement. Iteration of rule construction involves selecting rules with unterminated construction, selecting rule refinements associated with high accuracies, and iterating a rule refinement, filtering and evaluation procedure to identify any refined rule usable to test data. Rule development may use first order logic or Higher Order logic.

Network configuration management by model finding

Complex, end-to-end network services are set up via the configuration method: each component has a finite number of configuration parameters each of which is set to definite values. End-to-end network service requirements can be on connectivity, security, performance and fault-tolerance. A number of subsidiary requirements are created that constrain, for example, the protocols to be used, and the logical structures and associated policies to be set up at different protocol layers. By performing different types of reasoning with these requirements, different configuration tasks are accomplished. These include configuration synthesis, configuration error diagnosis, configuration error fixing, reconfiguration as requirements or components are added and deleted, and requirement verification. A method of performing network configuration management by model finding formalizes and automates such reasoning using a logical system called Alloy. Given a first-order logic formula and a domain of interpretation, Alloy tries to find whether the formula is satisfiable in that domain, i.e., whether it has a model. Alloy is used to build a Requirement Solver that takes as input a set of network components and requirements upon their configurations and determines component configurations satisfying those requirements. This Requirement Solver is used in different ways to accomplish the above reasoning tasks.
