20120011204 | AUTOMATED AGING OF CONTACTS AND CLASSIFYING RELATIONSHIPS - One or more interactions between a first user and a second user of a social networking system are identified. Each respective interaction of the one or more interactions is scored based on a group score and a time penalty. The group score is based on the number of users in the respective interaction and the time penalty is based on a time between a current time and a time of a last interaction between the first user and the second user. A relationship ranking that measures the first user's affinity towards the second user is determined, where the relationship ranking comprises one or more interaction scores. An indicator representing the relationship ranking is sent to a client for display. | 01-12-2012 |
20120124479 | Method And System For Tagging Content - Systems and methods for tagging digital content are provided. In some embodiments, a method comprises receiving and storing personal data of a first user of an internet-based social network. The personal data of the first user can include one or more digital images or other digital content that the first user is willing to share with other users of the social network. Accordingly, a request from a second user of the internet-based social network can be received to view some of the digital content of the first user. A viewer image can be used to tag the digital content of the first user allowing the owner of the digital content to quick determine the viewers. The viewer image can be a personal profile picture, an image, an icon, an avatar (two-dimensional or three-dimensional), or other on-screen representation that includes a visual indicator of the second user. | 05-17-2012 |
20120124508 | Method And System For A Personal Network - Systems and methods for asynchronous communications within an information sharing platform are provided. Traditional social network models use bi-directional friendship or unidirectional following. In contrast to these models, embodiments of the present invention provide for a unidirectional sharing friendship model. The unidirectional friendship model allows people to share information through a path of communications with a set of recipients selected by the sharer. | 05-17-2012 |
20130339449 | Method and System for Tagging Content - Systems and methods for tagging digital content are provided. In some embodiments, a method comprises receiving and storing personal data of a first user of an internet-based social network. The personal data of the first user can include one or more digital images or other digital content that the first user is willing to share with other users of the social network. Accordingly, a request from a second user of the internet-based social network can be received to view some of the digital content of the first user. A viewer image can be used to tag the digital content of the first user allowing the owner of the digital content to quick determine the viewers. The viewer image can be a personal profile picture, an image, an icon, an avatar (two-dimensional or three-dimensional), or other on-screen representation that includes a visual indicator of the second user. | 12-19-2013 |
20140074937 | Automated Aging of Contacts and Classifying Relationships - One or more interactions between a first user and a second user of a social networking system are identified. Each respective interaction of the one or more interactions is scored based on a group score and a time penalty. The group score is based on the number of users in the respective interaction and the time penalty is based on a time between a current time and a time of a last interaction between the first user and the second user. A relationship ranking that measures the first user's affinity towards the second user is determined, where the relationship ranking comprises one or more interaction scores. An indicator representing the relationship ranking is sent to a client for display. | 03-13-2014 |

20100087682 | Low metal loaded, catalyst compositions including acidic mixed metal oxide as support - The invention provides a catalyst composition composed of a support portion and a catalyst portion. The support portion includes an acidic mixed metal oxide including a transitional alumina and a second metal oxide. The transitional alumina can comprise delta or theta alumina, in combination with other transitional phases, or an alpha or gamma alumina. The second metal oxide has a weight percentage that is less than the weight percentage of alumina. The catalyst portion is 25 weight percent or less of the catalyst composition and is composed of nickel and rhenium. The catalyst portion includes nickel in an amount in the range of 2 to 20 weight percent, based upon total catalyst composition weight, and there is no boron in the catalyst portion. | 04-08-2010 |
20100094007 | Methods of making cyclic, N-amino functional triamines - The present invention provides strategies for making cyclic triamines. Reactant media including certain precursors and/or certain types of catalysts can be converted into cyclic triamines with improved conversion and selectivity. The strategies can be incorporated into reactions that involve transamination schemes and/or reductive amination schemes. In the case of transamination, for instance, using transamination to cause ring closure of higher amines in the presence of a suitable catalyst leads to desired cyclic triamines with notable conversion and yield. In the case of reductive amination, reacting suitable polyfunctional precursors in the presence of a suitable catalyst also yields cyclic triamines via ring closure with notable selectivity and conversion. Both transamination and reductive amination methodologies can be practiced under much milder temperatures than are used when solely acid catalysts are used. Preferred embodiments can produce reaction mixtures that are generally free of salt by-products. | 04-15-2010 |

20100137642 | Low metal loaded, alumina supported, catalyst compositions and amination process - The present invention provides catalyst compositions useful for transamination reactions. The catalyst compositions have a catalyst support that includes transitional alumina, use a low metal loading (for example, less than 25 wt. %), and do not require the presence of rhenium. The catalyst compositions are able to advantageously promote transamination of a reactant product (such as the transamination of EDA to DETA) with excellent activity and selectivity, and similar to transaminations promoted using a precious metal-containing catalyst. | 06-03-2010 |
20120238780 | LOW METAL LOADED, CATALYST COMPOSITIONS INCLUDING ACIDIC MIXED METAL OXIDE AS SUPPORT - The invention provides a method of transaminating a reactant with a catalyst composition comprising support and catalyst portions. The support includes an acidic mixed metal oxide including a transitional alumina and a second metal oxide. The transitional alumina can comprise delta or theta alumina, in combination with other transitional phases, or an alpha or gamma alumina. The second metal oxide has a weight percentage less than the weight percentage of alumina. The catalyst portion is 25 weight percent or less of the catalyst composition and is composed of nickel and rhenium. The catalyst portion includes nickel in an amount in the range of 2 to 20 weight percent, based upon total catalyst composition weight, and there is no boron in the catalyst portion. The method provides high activity and selectivity for reactant transamination to a desired product while minimizing the formation of unwanted cyclic products. | 09-20-2012 |
