System and method for managing information flow between members of an online social network

An online social network is provided in which members of the online social network control who may view their personal information and who may communicate with them. The members control who may view their personal information by setting a visibility preference. A member may not view another member's full personal profile if the measure of relatedness between the two is greater than the visibility preference of the other member. The members also control who may communicate with them by setting a contactability preference. A member may not communicate with another member if the measure of relatedness between the two is greater than the contactability preference of the other member.

System and method for ranking search results using file types

Search results of a search query on a network are ranked according to an additional ranking function for the prior probability of relevance of a document based on document property. The document property may be the document's file type, the file size, the document language, or another query-independent property of the document. The query-independent values for each document property may be weighted according to relevance measurements of the document based on the document property. As more relevance measurements of the documents may be obtained, the query-independent values for each document property may be updated to reflect the new measurements.

System and method for generating normalized relevance measure for analysis of search results

A system and related techniques permit a search service operator to access a variety of disparate relevance measures, and integrate those measures into idealized or unified data sets. A search service operator may employ self-learning networks to generate relevance rankings of Web site hits in response to user queries or searches, such as Boolean text or other searches. To improve the accuracy and quality of the rankings of results, the service provider may accept as inputs relevance measures created from query logs, from human-annotated search records, from independent commercial or other search sites, or from other sources and feed those measures to a normalization engine. That engine may normalize those relevance ratings to a common scale, such as quintiles, percentages or other scales or levels. The provider may then use that idealized or normalized combined measure to, for example, train the search algorithms or heuristics to arrive at better or more accurate results.

Search engine with increased performance and specificity

The present invention discloses a system and methods for retrieval of most relevant information from a given digital data repository. This is done in the first step by verifying two conditions of relevance, presence of query words plus presence of at least one type of relationship between the words in the data record. Additionally a numeric relevance score is computed for each relevant record, such that they can be sorted descendingly according to this relevance metric. The most relevant results will be shown first, while irrelevant records are eliminated. This reduces the volume of the results substantially. The information retrieval system according to this invention includes: a data pre-processing component where multiple steps of processing is performed, a second new data repository where the modified data is stored, a user interface with the capability of real-time translation of user's query, a search engine, and computing hardware in a distributed architecture.

Mined semantic analysis techniques (MSA) include generating a first subset of concepts, from a NL corpus, that are latently associated with an NL candidate term based on (i) a second subset of concepts from the corpus that are explicitly or implicitly associated with the candidate term and (ii) a set of concept association rules. The concept association rules are mined from a transaction dictionary constructed from the corpus and defining discovered latent associations between corpus concepts. A concept space of the candidate term includes at least portions of both the first and second subset of concepts, and includes indications of relationships between latently-associated concepts and the explicitly / implicitly-associated concepts from which the latently-associated concepts were derived. Measures of relatedness between candidate terms are deterministically determined based on their respective concept spaces.

A method and apparatus are provided for organizing media files using parameters obtained from the visual content and metadata of the media files. Using machine learning, an algorithm is trained to apply user preferences to organize the media files. The user indicates their preferences by viewing the media files and selecting relevancy measures and organizational actions for a subset of the media files (i.e., training data). Using the media-file parameters, the algorithm calculates relevancy values for respective media files. The algorithm is trained to minimize the error between the calculated relevancy value and the user determined relevancy measures of the training data. The media-file parameters can include, e.g., the blurriness of and facial and pattern recognition of the visual content; the source, location, time, edit history, and the frequency and recency of access to the media files as recoded in the metadata.

The system comprises a laser, wherein laser light emitted by the laser passes through a semi-permeable and semi-reflective mirror after being expanded for illuminating a tested object and a reference object surface respectively; the tested object surface and the reference object surface are imaged simultaneously on the target surface of a CCD (Charge Coupled Device) camera through an imaging lens by means of the semi-permeable and semi-reflective mirror; the semi-permeable and semi-reflective mirror is arranged obliquely at an angle of 45 degrees relative to incident rays; and when a reference path exists, object surface speckles and reference surface speckles are interfered with mutually on the target surface of the CCD camera to form an interference speckle image for measuring an off-plane displacement component. A reference substance light path is removed, a speckle image on the object surface is acquired, and two components of in-plane displacement are calculated by using two speckle images acquired before and after deformation. A typical digital speckle light path which is sensitive to the off-plane displacement is utilized, so that the in-plane displacement and speckle interference off-plane displacement of a speckle relevance measuring object are realized, and three-dimensional displacement measurement is realized; and and the system and the method have the advantages of simple light path, and easiness and rapidness for operating and processing data.
