A system for generating a carpooling prediction includes a computer that performs the operations of receiving a query for a ride match location from a user computing device. The query includes a given destination location and target arrival time for reaching the destination. The computer is operative to transmit coordinates to the user computing device of a location where a user can find other users willing to rideshare. For a number of passengers that are looking for a ride to a given destination during a given time, the computer is operative to predict a number of drivers that will pass or end at the given destination during a given time interval that includes the target time. For a number of drivers that are looking to offer a ride to a given destination during a given time, the computer is further operative to predict a number of passengers that will pass or wait at a given node, for example, along the drivers' route or alternate route, for reaching the destination. Based on the prediction, the computer is further operative to transmit coordinates to the user computing device corresponding to a location where the at least one driver or passenger is predicted to pass or be located. The computer is further operative to process a transaction between two users in response to receiving a communication from a remote user device authenticating the transaction between the two users.

Predictive model for supporting carpooling

A system and method predict an optimal machine translation system for a first of a set of users. The method includes, for each of the users, providing a respective user profile which includes rankings for at least some machine translation systems from a set of machine translation systems. The user profile of the first user is updated, based on the user profiles of at least a subset of the other users. The updating includes generating at least one missing ranking. An optimal translation system for the first user from the set of machine translation systems is predicted, based on the updated user profile computed for the first user.

A system and method for preserving privacy of evidence are provided. In the method, an encrypted first image is generated by encrypting a first image acquired at a first location with a symmetric cryptographic key that is based on first information such as a license plate number extracted from the first image and first metadata associated with the first image, such as a time at which the first image was acquired. When a link is established between a second image and the first image, for example, through visual signature matching, the symmetric cryptographic key can be reconstructed, without having access to the first image, but based instead on the first metadata and information extracted from the second image. The reconstructed symmetric cryptographic key can then be used for decryption of the encrypted image to establish evidence that the license plate number was indeed extracted from the first image.

Privacy-preserving evidence in ALPR applications

A method and system are disclosed for wireless payment and information collection. A central system generates a personalized application including unique application and transaction identifiers, security keys, and signatures for a user device. The user device implements the personalized application in order to access the services of the associated network. Tags, capable of short-range communication with the user devices, are deployed to service access points of the associated network. The tags and user device mutually authenticate and share identifiers. Validation of the user device results in the tag updating an irreversible counter, generating transaction certificate, and logging this transaction information. The transaction certificate and a portion of the log are communicated to the user device, and service is granted. The user device transmits the transaction information and log to the central system for billing when a network connection is available.

A system and method predict the translation quality of a translated input document. The method includes receiving an input document pair composed of a plurality of sentence pairs, each sentence pair including a source sentence in a source language and a machine translation of the source language sentence to a target language sentence. For each of the sentence pairs, a representation of the sentence pair is generated, based on a set of features extracted for the sentence pair. Using a generative model, a representation of the input document pair is generated, based on the sentence pair representations. A translation quality of the translated input document is computed, based on the representation of the input document pair.

Predicting the quality of automatic translation of an entire document

A computer implemented system and method are disclosed for updating an electronic calendar. The method includes receiving an electronic message in a natural language in which a change in role is expressed and, with a natural language processor implemented by a computer processor, automatically detecting the change in role within the email message, optionally storing the change in role in a contacts database, and proposing updates for entries in an electronic calendar based on the detected change in role.

An initial organizational table for a document is determined based on textual similarity between entries of the organizational table and target text fragments and not taking into account text formatting. A classifier is trained to identify text fragment pairs consisting of entries of the organizational table and corresponding target text fragments based at least in part on text formatting features. The training employs a training set of examples annotated based on the initial organizational table. The initial organizational table is updated using the trained classifier.

Table of contents extraction based on textual similarity and formal aspects

A method for identifying header/footer content of a document, in order to sequence text fragments comprising recognizable text blocks as derived from the document. The textual variability of lines comprised of text blocks, including the different kinds of text blocks within the line is analyzed for assessment of textual variability. Header/footer zones are defined by textual content having a low textual variability. An alternative embodiment identifies pagination constructs by comparing selected text-boxes for similarity and proximity and clustering the text boxes satisfying a predetermined similarity value, wherein the clustered text boxes are deemed to comprise pagination constructs.

Method and apparatus for detecting pagination constructs including a header and a footer in legacy documents

A method of detection of numbered captions in a document includes receiving a document including a sequence of document pages and identifying illustrations on pages of the document. For each identified illustration, associated text is identified. An imitation page is generated for each of the identified illustrations, each imitation page comprising a single illustration and its associated text. For a sequence of the imitation pages, a sequence of terms is identified. Each term is derived from a text fragment of the associate text of a respective imitation page. The terms of a sequence complying with at least one predefined numbering scheme which defines a form and an incremental state of the terms in a sequence. The terms of the identified sequence of terms are construed as being at least a part of a numbered caption for a respective illustration in the document.

Detection of numbered captions

A method and system for document processing allow a service provider to process a document without having access the textual content of the document. The system includes memory which receives an encoded source document from an associated client system. The encoded source document includes structural information and encoded content information. The encoded content information includes a plurality of encoded tokens generated by individually encoding each of a plurality of text tokens of the source document. The structural information includes location information for each of the plurality of text tokens. A processing module processes the encoded document to generate a modified document, without decoding the encoded tokens. A transmission module transmits the modified document to an associated client system whereby the client system is able to generate a transformed document based on the modified document and the plurality of text tokens.

Confidentiality preserving document analysis system and method

A method and system are disclosed for post optical character recognition font size determination. Optical character recognition output from an optical character recognition engine that includes character and bounding box information is aggregated into character strings. Measurements are then collected from each character in each character string that correspond to alignment heights of the top or bottom of the character with an ascender-line, a cap-line, a digit-line, a mean-line, a base-line, or a descender-line. Histograms are formed for each of these heights for each character string from the collected measurements. Based on the histograms, a pivot height is selected and used to determine the relative font size of the character string. The relative font size is normalized using a preselected factor associated with the selected pivot height. The normalized font size is then output as the font size of characters in the optical character recognition output.

Post optical character recognition determination of font size

A system and method generate an ontology of linked resources. The method includes providing a policy comprising at least one logical rule which is to hold across an ontology of linked resources and initializing a set of resources with an initial subset of the set of resources, each resource in the initial subset being identified by a respective link. Each of the resources in the subset is processed, which includes populating the ontology with a corresponding member of a resource class, for a resource that is valid against a schema, asserting the member's class as a class specific to the schema of the validated resource in the ontology and providing a dependency specification for extracting links within the resource, each extracted link identifying one of the set of resources. A link property is asserted in the ontology for a link between the resource of the subset containing an extracted link and the resource identified by the extracted link and the ontology populated with a member of the resource class for each newly identified resource. A verification that the at least one logical rule holds across the set of resources in the ontology is performed.

Enforcing policies over linked XML resources

A digital processing device is configured to perform a method comprising: identifying logical page numbers of a document, the identifying constrained to identify either zero or one logical page number per page of the document, the logical page numbers and an ordering of the pages of the document defining an ordered sequence of logical page numbers; identifying a sequence of logical page number references in the document, each logical page number reference matching one of the logical page numbers of the document; and selecting a sub-sequence of the sequence of logical page number references for which corresponding logical page numbers are in a nondecreasing order in the ordered sequence of logical page numbers. The sub-sequence is used in organizing the document, for example by generating hyperlinks linking the logical page number references of the selected sub-sequence with corresponding pages indicated by the logical page numbers.

Document organizing based on page numbers

In a method for identifying a table of contents in a document, an ordered sequence of text fragments is derived from the document. A table of contents is selected as a contiguous sub-sequence of the ordered sequence of text fragments satisfying the criteria: (i) entries defined by text fragments of the table of contents each have a link to a target text fragment having textual similarity with the entry; (ii) no target text fragment lies within the table of contents; and (iii) the target text fragments have an ascending ordering corresponding to an ascending ordering of the entries defining the target text fragments.
