Abstract: To improve traditional keyword based search engines, the present inventors devised, among other things, systems, methods, and software that use word co-occurrence probabilities not only to identify documents conceptually related to user queries, but also to score and rank search results. One exemplary system combines inverse-document-frequency searching with concept searching based on word co-occurrence probabilities to facilitate finding of documents that would otherwise go unfound using a given query. The exemplary system also allows ranking of search results based both on both keyword matching and concept presence, promoting more efficient organization and review of search results.

Abstract: The present invention provides a corpus-independent method for determining relevancy of terms to content of text appearing in a document by analyzing the document itself. Conventional information extraction, or other methods, may be applied to a document to generate a list of terms. The invention analyzes the document using relevancy scoring algorithms to determine a term relevancy score representing the term's relevance to the text contained in the document. The scores, including an aggregate score, may be normalized in the process. Based on relevancy scoring, terms are then ranked and further processed. In this manner relevancy is determined based on the subject document itself and by analyzing the occurrences and locations of the terms within the document. Additional techniques may be applied to relate the relevancy scores generated by the present invention to a corpus or collection of documents.

Abstract: The present invention provides a valve assembly designed to regulate air flow through a musical instrument and is designed to avoid bumps typically associated with valve construction that result in distortion and other harmful effects on vibrating columns of air that pass there-through. The valve assembly comprises: a cylindrical-shaped valve casing having openings formed therein that define at least one ingress and at least one egress through which vibrating columns of air pass; and a valve piston received within the valve casing and linearly displaceable therein, the valve piston comprising at least one passageway having a cross-section that is open and u-shaped, whereby other passageways formed in the valve piston are bump-free.

Abstract: The present invention relates to enhanced workflow solutions for authors (e.g., researchers, scientists, and scholarly authors) and publishers (e.g., journals and professional and technical societies) in preparing documents in structured format for facilitating efficient and accurate validation of references cited or included in papers and other submissions for publication or for review. An author prepares a document containing a set of cited references using a formatting structure. A system includes a processor to process the document to extract embedded metadata associated with the set of cited references. The processor executes code associated with a reference validation software module and automatically recognizes the formatting structure and the embedded metadata. The processor automatically extracts the embedded metadata and compares the extracted metadata against an authority database to determine the validity of the set of cited references.

Abstract: The present invention provides a feedback gate bias circuit for use in radio frequency amplifiers to more effectively control operation of LDFET, GaNFET, GaAsFET, and JFET type transistors used in such circuits. The invention provides a transistor gate bias circuit that senses drain current and automatically adjusts or biases the gate voltage to maintain drain current independently of temperature, time, input drive, frequency, as well as from device to device variations. The invention provides additional circuits to provide temperature compensation, RF power monitoring and drain current control, RF output power leveler, high power gain block, and optional digital control of various functions.

Abstract: The present invention comprises a system and method for automatically processing one or more citations contained within a document while the document is presented by a document rendering application. The method of the present invention comprises scanning the document to identify an unformatted citation and parsing the unformatted citation to determine one or more citation terms. One or more citation libraries are queried to find citations comprising the one or more citation terms. A citation falling within the scope of the query is selected and inserted into the document.

Abstract: The present invention provides a computer-implemented method for automatically generating and placing documents associated with a tax and accounting related engagement, for example assessing risks associated with an audit. A user is presented with a plurality of audit items and a set of risk levels associated with the audit items and may also be presented with a plurality of prompts designed to elicit a set of responses from the user. The set of user responses being associated with a set of risks associated with the audit. The set of risk levels being associated with a set of assertions associated with the audit items and may include first and second risk levels of different degrees. The method further includes processing a set of responses received from the user in response to the items presented. The method includes automatically generating a suggested audit approach that is based at least in part on the processed responses.

Abstract: An information-retrieval system includes a server that receives queries for documents from client devices and means for outputting results of queries to the client devices, with the results provided in association with one or more interactive control features that are selectable to invoke display of information regarding entities, such as professionals, referenced in the results.

Abstract: A method and system receives one or more target distribution amounts corresponding to currency totals for one or more foreign entities to distribute to one or more domestic entities in one or more years, the foreign entities being direct or indirect subsidiaries of the one or more domestic entities, then it receives entity data pertaining to tax relevant attributes for the one or more domestic and foreign entities over the one or more years, and receives distribution constraints for each foreign entity, the distribution constraints including a minimum distribution amount and a maximum distribution amount for each entity in each year. The method and system creates one or more distribution scenarios including corresponding tax costs based on the entity data and the distribution constraints and identifies a distribution scenario from the one or more distribution scenarios having the lowest tax and meeting the one or more target distribution amounts.

Abstract: In an embodiment one or more alternate entity structures are created in response to a base entity structure. A tax liability is determined for each alternate entity structure and the base entity structure; furthermore, a result is generated in response to comparing each of the determined tax liabilities with one another.

Abstract: The present invention provides a Distinct Author Identification System (“DAIS”) for disambiguating data to discern author entities and link or associate authorships with such author entities. The invention provides powerful disambiguation processes applied across one or more databases to yield a disambiguated authority database of authors. An entire database of publications may be processed by the DAIS to group/link authorships and to identify author entities. The author entities may then be matched or associated with actual authors to establish an authority database of authors. After initial evaluation, the DAIS may be used to reevaluate some or all of the database(s) and/or the authority database established by the DAIS may be used to add or update information. DAIS may use “hierarchical clustering” to link authorships and identify authors based on authorship similarity. DAIS evaluates the likelihood that authorships are from the same author.

Abstract: Many companies provide online search facilities that enable users to conduct computerized searches for documents. Unfortunately, these searches frequently provide results that include duplicate documents—that is, documents that are completely or substantially identical to each other. This problem is particularly vexing when searching news stories, for example. Moreover, the duplicate documents are intermixed in the search results, leaving users to manually manage the complexities of identifying and/or filtering them. Accordingly, the present inventors devised systems, methods, and software that facilitate the identification and/or grouping of duplicate documents in search results.
