20080228769 | Medical Entity Extraction From Patient Data - Members of a medical entity class are extracted from patient data. A semi-supervised approach uses one or more initial medical terms such as terms from an ontology, for a given category or medical canonical entity. A larger set of medical terms is extracted from the medical information. In one example, the extraction is performed using lexical surface form features, rather than syntactical parsing. | 09-18-2008 |
20080288292 | System and Method for Large Scale Code Classification for Medical Patient Records - A method for training classifiers for ICD-9 patient codes includes providing a set of documents regarding patient hospital visits, combining the documents for each patient visit to create a hospital visit profile, defining a feature as an ngram with a frequency of occurrence greater or equal to a predetermined value that does not appear in a standard list of ngrams, processing the profiles to remove redundancy at a paragraph level and perform tokenization and sentence splitting, performing feature selection, randomly dividing the documents into training, validation, and test sets, and training a set of binary classifiers using a weighted ridge regression, each binary classifier targeting a single ICD-9 code using the training set, wherein each classifier is adapted to determining a specific ICD-9 code by analyzing a patient's hospital records. | 11-20-2008 |
20090024615 | System and Method for Creating and Searching Medical Ontologies - A method for creating and searching medical ontologies includes providing a semi-structured information source comprising a plurality of articles linked to each other, each article having one or more sections and each article is associated with a concept, creating a directed unlabeled graph representative of the information source, providing a plurality of labels, labeling a subset of edges, and assigning each unlabeled edge an equal probability of being assigned one of the labels. For each node, the probability of each outgoing edge is updated by smoothing each probability by an overall probability distribution of labels over all outgoing edges of each node, and the probability of each incoming edge is updated the same way. A label with a maximum probability is assigned to an edge if said maximum probability is greater than a predetermined threshold to create a labeled graph. | 01-22-2009 |
20090106238 | Contextual Searching of Electronic Records and Visual Rule Construction - A web-based system for visual construction of logical rules includes a server, a network, and client operatively connected to the server via the network. The server includes a database and a search engine. The client includes a web-based visual rule building application including selectable windows for displaying and visually editing terms, logical operators, logical rules for storage in the database. The logical rules are generated by visually selecting at least one of the terms and logical operators from the windows. The server may further include a search engine configured to perform at least one of a direct search or a contextual search for an entered query string in records stored in the database and the client may include a visual interface for displaying results of the searches. The search results generated by the search engine may be stored as terms in the database for subsequent rule generation. | 04-23-2009 |
20100049756 | Medical Intelligence Framework - A framework executing on a computational structure and supporting a plurality of simultaneously executing software applications with a shared layer, wherein the framework is disposed between the plurality of applications and a set of data sources, the framework decomposing, processing, and analyzing data passed between the plurality of applications and the data sources into information elements. | 02-25-2010 |

20120323694 | NON-INVASIVE SAMPLING AND FINGERPRINTING OF ONLINE USERS AND THEIR BEHAVIOR - A system, method, apparatus, and processor readable non-transitive storage media are described for matching items in large datasets based on non-invasive fingerprints of users so that collected metric data for advertisements (media) and behavioral data may be reconciled and analyzed. Since user fingerprints may not generate a unique one to one correspondence or mapping under certain constraints, the various embodiments employ a sampling method that optimally matches the output of a random sampling of non-invasive fingerprints. The use of non-invasive fingerprints and specialized sampling enables the various embodiments to provide advanced analytics for advertising content and metric data in targeted behavior advertising campaigns. To compare impressions with user profile data, the various embodiments employ in part the time stamp dimension of user profiles to generate temporally unique persistent non-invasive fingerprints. | 12-20-2012 |
20130282493 | NON-UNIQUE IDENTIFIER FOR A GROUP OF MOBILE USERS - Embodiments are directed towards collecting, aggregating and indexing unique and non-unique user data from a plurality of users. The result for a query of this indexed aggregation of user data is provided in a plurality of sub-sets of aggregated user data. Each subset of aggregated user data corresponds to a particular portion of the plurality of users. Also, each of these particular portions of the users is set at least large enough to provide general anonymity for the individual users. User data may be collected by one or more user data suppliers and provided to a user data aggregator. In some embodiments, user data may be collected as unique user data, non-unique user data, or any combination thereof. In some embodiments, user data may be aggregated by zip code, expanded zip code, and/or one or more attributes. | 10-24-2013 |
