In one embodiment, a method includes specifying a client profile including at least one scenario of interest, the scenario of interest being formulated in an event calculus formalism; analyzing a portion of text for relevant information at least partially described by the scenario of interest; detecting relevant information including detecting a positive match between at least part of information relevant to the scenario of interest and at least part of the portion of text being analyzed; upon detecting such relevant information, extracting the relevant information; representing the extracted relevant information in the event calculus formalism; and performing an inference process on the extracted relevant information represented in the event calculus formalism. ## Claims ### Claim 1 A method comprising using a computer to automatically process a plurality of documents containing text to extract information of interest to a client, the processing performed by the computer including: creating a client profile based on at least one scenario of interest to the client, the scenario of interest including a sequence of events, the client profile including an ordering of event representations that are of interest to the client; conceptually decomposing the text in the documents into decomposed data; applying event calculus axioms and formula to the client profile and the decomposed data to detect relevant information in the documents; and upon detecting such relevant information, extracting the relevant information from the documents. ### Claim 2 (depends on 1) The method of claim 1, wherein the processing further comprises performing an inference process on the extracted relevant information, including at least one of deductively determining when the extracted relevant information embodies the scenario of interest and abductively determining when the extracted relevant information embodies a scenario of interest. ### Claim 3 (depends on 2) The method of claim 2, wherein deductively determining when the extracted relevant information embodies the scenario of interest includes at least one of confirming the occurrence of the scenario of interest in the extracted relevant information and predicting the occurrence of the scenario of interest in the extracted relevant information. ### Claim 4 (depends on 3) The method of claim 3, wherein predicting the occurrence of the scenario of interest includes determining that the extracted relevant information only partially embodies the scenario of interest, and determining that a confidence weight attached to the partially-embodied scenario of interest is satisfied. ### Claim 5 (depends on 1) The method of claim 1, wherein the processing further comprises performing an inference process on the extracted relevant information, including abductively determining a most likely profiled scenario compatible with a plurality of user-specified events. ### Claim 6 (depends on 5) The method of claim 5, wherein abductively determining a most likely profiled scenario includes performing an inference process based on a logical formula represented as a conjunction F of a set of logical formulae describing events and activities drawn from the portion of text, the conjunction F including the plurality of user-specified events, and finding a logical description Δ(M) of reported events such that F=Σ(B)Σ(E)Δ(N)Δ(M), where “” is the logical “AND” operator, and where: Σ(B) is a background theory comprising axioms for change in space-time, including changes in temporal and spatial locations. ### Claim 7 (depends on 1) The method of claim 1, wherein the processing further comprises performing an inference process on the extracted relevant information, including determining that one or more confidence weights attached to a partially-embodied scenario of interest are satisfied. ### Claim 8 (depends on 1) The method of claim 1, wherein creating a client profile includes specifying at least one of an event and a state of affairs integrated with at least one participant;
