  • This invention is directed to methods and systems for determining similarity between user profile data, for a network having a plurality of users, and to methods for facilitating co-location of network users.
  • Embodiments of the invention relate in particular to social networking and mobile communication systems and more specifically to social connections and encounters used to search and find activity partners among like-minded individuals with similar interests.
  • Previous mobile apps offer friend finder and dating services using email ID, mobile number or even a social networking account for registering a user. They generally match subscriber profiles using profile information, responses to questionnaires or quizzes and location information of a subscriber.
  • the aforementioned services offer the convenience of a finding potential partners or friends in the virtual world using their computers or mobile devices. However they do not address one or more of the following issues of critical importance to online and especially mobile dating subscribers and subscribers wishing to encounter new friends in real life.
  • Such questionnaires also require large amounts of complex computational processing, and can therefore be a drain on resources, for example in low-margin server farms, or in mobile user devices having little battery life.

  • one embodiment of a first aspect of the invention can provide a method of determining similarity between user profile data, for a network having a plurality of users, the method comprising:; on presentation of media presentation items from a set of media presentation items to a first user and to a second user of the network, recording respective user device inputs from the first and second users in response to each media presentation item; and comparing the first and second user response inputs for each media presentation item to determine a similarity measure for a first and second user profile data pair.
  • the set of media presentation items may have been obtained beforehand.
  • the method may comprise identification of media presentation items at a remote resource, and arranging or otherwise instructing for media presentation items from the remote resource to be presented to the users.
  • the user responses should also be more objective, as the input from the user is a simple response to a media item, rather than to a complex question inviting subjective assessment by the user.
  • This method also removes the need for an up-front questionnaire, and also for a lengthy set of initial questions or statements, which can save computational load on a user device or server.
  • the step of recording comprises recording a user device input selecting one of the set of available responses.
  • the response set may be a binary yes/no, like/dislike,
  • the response set may also comprise ratings or rankings of the presentation item.
  • the step of comparing comprises identifying a media presentation item for which the first and second user responses match. For example, if the set of available responses is positive/negative (e.g. yes/no), a match may be that both users choose positive or both choose negative.
  • a "match" of user responses may include instances where the first and second user responses are identical; these are considered an "exact match”. But there may be other instances where the "match" is more broadly defined.
  • the step of comparing may comprise identifying a media presentation item for which the first and second user responses correlate to a sufficient extent that they can be considered for all intents and purposes to be a "match", or at least a good match. For instance, if one user responds to a particular media presentation item with a "strong like", and another user responds to the same media presentation with a "like”, a correlation may be identified that both users "like” that particular media presentation item, although one user likes it more than the other user. That may be sufficient to identify that the users are potentially compatible with one another, that they may be a potential match themselves. Or, this identified correlation may form part of an identification - along with their responses to other posters, for example - to an identification the users are a potential match.
  • the step of comparing comprises determining the similarity measure as a function of matches and/or non-matches of the responses of the first and second users to the set of media presentation items.
  • x1 is the number of matches (which may be or include the number of exact matches or may be or include the number of correlations), for the set of media presentation items for the first and second users, of a positive response;
  • x2 is the number of matches (which may be or include the number of exact matches or may be or include the number of correlations) of a negative response;
  • x3 is the number of non-matches of response. Further, where x1 or x2 is a count including identified correlations, further weighting can be applied to that in the calculation given that the correlation does not necessarily identify that the two users responded in precisely the same way to the same media presentation item; the weighting may account for slight differences in response, such as a "like” compared to "strong like".

  • the system is therefore dynamic and iterative, in contrast to previous systems in which all assessment of the user's tastes is done in an initial stage.
  • Figure 10 illustrates an example of a chat window accessible from user profiles ( Figure 7), providing a typical instant messaging option.
  • a chat window is shown to the user that shows the name of the user profile being viewed (1 001 ), and the messages so far exchanged (1002).
  • a message typing window is here shown at the bottom of the screen (1004).
  • the system also displays posters in the background behind the chat window, to highlight how the users responded to posters.
  • the full background screen 1005 is accessible by clicking a button or swiping, and the screen shows the indicators 1006 and 1007 of which user (indicated by the picture above) liked or disliked the poster.
  • the user can swipe to see the next poster in the series.
  • the posters can be made to appear sequentially behind the chat window, for example by a scrolling or fade in/out motion. This allows the users to instantly see how their interests match, and facilitates topics of conversation.
  • Figure 5 illustrates steps of a method according to another embodiment of the invention, concerning "hangspots".
  • the system first determines a similarity measure for user profile data between a first user and another network user (502). If this does not exceed a threshold (504), the method goes back to the first step, to find another user profile data set which may match more closely.
  • the first user is permitted access to the second user's user profile data (506), which includes their hangspot data.
  • This data is generated by the (second) user by first recording location and time or time period data for a planned activity, before the activity is to take place (508).
  • This can be a single activity, or more usually a series of activities. Users can upload an entire diary of their usual activities, such as going to work on a public transport vehicle between certain times on weekdays, going to a swimming pool on Sunday mornings, and the like.
  • the first user is permitted access to the location and time data for the planned activity (510), so that they can arrange to be at one of the places at a time or during a time period, in order to initiate an encounter.
  • Users can also control who can see their hangspots by setting an option to explicitly share it with a person, with everyone or with people who they have already initiated a conversation with.
  • RSVP RSVP concept
  • check-in may create excitement
  • checkout may offer a closure. It is believed that the combination of RSVP/check-in/checkout has not hitherto been available. ln previous systems, notification of a list or diary of a person's activities is not available in advance, so other users do not have an opportunity to join in. In others, there is no means of identifying persons attending who may be people interested in meeting a person like you; this is facilitated in embodiments of the invention by the matching score.
  • One advantage is that it may enable social encounters in real life at places where people normally hang out in such places as coffee shop, yoga classes, gym, parks, expos, resorts, cinema, restaurants etc.
  • the methods as described above help users target users they share mutual interests in real world things, chat with them instantly and establish a person rapport to some extent.
  • the relationships truly begin only when they meet in real life.
  • Embodiments of the invention address this issue of by facilitating social encounters in real life, wherein such encounters are informal in nature in a public place without any pressure to even meet or greet the other person.
  • Most encounters could just be a casual lookup of other people, checking out who they really are in person and studying how they look and act in the real world. Such encounters are very valuable to every user in deciding whether they like to initiate a relationship
  • a location could be any place on a map such as a public park (1 101 ) or a coffee shop (1 102).
  • the time or period when a user expects to hang out at the given location can be expressed in different ways that include but are not limited to specific date and time, days of week and time and duration with start and end date, for example, in a hangspot calendar. These hangspots are shared with other users as controlled by the user by choosing to share (1 104) with everyone matching their target criteria, who they communicate with, or specific persons explicitly.
  • the check out function can also be activated automatically, for example by a location function of a user's device.
  • a location function of a user's device In an example, a user may leave a geographical location, and a GPS function on the user's mobile device, linked to the software application for the hangspot, can alert the software that the user has left the location, toggling the check out.
  • the check in function can also be set to automatically sign a person into a location in this way.
  • certain of the above embodiments of the invention may be conveniently realized as a computer system (such as a server or mobile device) suitably programmed with instructions for carrying out the steps of the methods according to the invention.
  • a central processing unit 1304 is able to implement such steps as obtaining a set of media presentation items for presentation, on user devices, to users of the network; on presentation of media presentation items from the set to a first user and to a second user of the network, recording respective user device inputs from the first and second users in response to each media presentation item; and comparing the first and second user response inputs for each media presentation item to determine a similarity measure for a first and second user profile data pair.
  • Data can be received by port 1305 which could be a reader for portable data storage media (e.g. CD-ROM); a direct link with apparatus or a connection to a network.

Abstract

L'invention concerne des procédés et des systèmes pour déterminer une similarité entre des données de profil d'utilisateur, pour un réseau ayant une pluralité d'utilisateurs. Un ensemble d'éléments de présentation multimédia est obtenu pour une présentation, sur des dispositifs d'utilisateur, à des utilisateurs du réseau. Lors de la présentation d'éléments de présentation multimédia provenant de l'ensemble à un premier utilisateur et à un second utilisateur du réseau, des entrées de dispositif d'utilisateur respectives provenant des premier et second utilisateurs en réponse à chaque élément de présentation multimédia sont enregistrées. Les entrées de réponse des premier et second utilisateurs pour chaque élément de présentation multimédia sont ensuite comparées pour déterminer une mesure de similarité pour une paire de données de profil des premier et second utilisateurs. Les éléments de présentation multimédia peuvent prendre la forme, par exemple, de publicités de type affiches interactives. L'invention concerne également un procédé pour faciliter la co-implantation de premier et second utilisateurs d'un réseau.
