Abstract

The present invention relates to a system and method for recommending multimedia elements comprising:

• • means for identifying the number of times that a user has accessed or accessed and played a musical piece or multimedia element in a certain time period, and
  • means for arranging said identified pieces in the form of a preference or relevance profile for said user, taking into account the following indicators:
    • number of accesses, or accesses and plays, per piece for said certain time period, and
    • number of accesses, or accesses and plays, per piece during a sub-period located in a last section of said certain time period.

The method proposes a recommendation made from a plurality of preference profiles of multiple users, generally comparing the preference profile of a user with the remaining preference profiles of other users.

Claims

1-27. -27. (canceled)

28. A system for recommending multimedia elements, preferably applicable to the music recommendations to a user, of the type comprising:

means for accessing and playing multimedia elements by at least one user;

means for ascertaining the multimedia element preferences of said user, who is at least one in number,

characterized in that said means for ascertaining the multimedia element preferences of said user comprise;

identification means for automatically identifying the number of times that said user has accessed or accessed and played at least in part each one of said multimedia elements in a certain time period, and

arranging means associated to said identification means for arranging said identified pieces in the form of a preference or relevance profile for said user, who is at least one in number, taking into account the following indicators;

said number of accesses, or accesses and plays, per multimedia element for said certain time period, and

the number of accesses, or accesses and plays, per multimedia element during a sub-period located in a last section of said certain time period.

29. The system according to claim 28, characterized in that it comprises a database associated to said arranging means for storing a series of preference profiles, each of which corresponding to a user and obtained according to said arrangement for each one of said users according to said indicators.

30. The system according to claim 29, characterized in that said identification means, said arranging means and said database are synchronously associated so as to enable updating the preference profiles of the database for each user.

31. The system according to claim 29, characterized in that it comprises recommendation supply means associated to said database for selecting and supplying to each of the users at least one recommendation of a multimedia element according to its relevance within a certain number of said preference profiles.

32. The system according to claim 31, characterized in that it comprises a series of first devices, at least one per user, arranged in a series of local points, each of them accessible by the user, and at least one second device arranged at a remote point with regard to said local points, said second device being bi-directionally intercommunicated with all the first devices so as to allow said identification and said supply of recommendations, and each one of said first devices comprising at least part of said means for accessing and playing multimedia elements, and said second device said database.

33. The system according to claim 31, characterized in that said first devices are, each one of them, at least one of the group consisting of:

mobile telephones, electronic agendas, personal computers, television sets, audio equipment and video equipment, and said second device is a computer acting as a service server.

34. The system according to claim 32, characterized in that said first devices are intercommunicated with said second device through a communications network, which is one of the group consisting of:

mobile or land telephony network, local, mid- or long-range computer network, land or wireless television network.

35. The system according to claim 32, characterized in that said first devices comprise selection means associated to said means for ascertaining the preferences for each user to select at least one list out of a series of lists of multimedia elements and thus modify his/her respective user profile in said database.

36. The system according to claim 35, characterized in that said first devices comprise activity detection means associated to said selection means so as to detect the activity carried out by a user and selecting, according to said activity, at least one list out of a series of lists of multimedia elements and thus modifying his/her respective user profile in said database.

37. A method for recommending multimedia elements, preferably applicable to the music recommendation to a user, comprising the following steps:

a) identifying the number of times that at least one user has accessed or accessed and played at least in part each one of a series of multimedia elements in a certain time period, and

b) arranging said identified multimedia elements in the form of a preference or relevance profile for said user, who is at least one in number, taking into account;

a first indicator relating to said number of accesses or accesses and plays per multimedia element for said certain time period,

a second indicator relating to the number of accesses or accesses and plays per multimedia element during a sub-period located in a last section of said certain time period, and

said arrangement is carried out by assigning different weights or levels of importance to the different identified multimedia elements depending on said indicators.

38. The method according to claim 37, characterized in that it comprises assigning weights or levels of importance to the multimedia elements identified as accessed or accessed and played within said sub-period greater than those of the accessed or accessed and played multimedia elements outside of it.

39. The method according to claim 37, characterized in that said first and second indicators have a different level of importance from one another when each of said user profiles is obtained.

40. The method according to claim 37, characterized in that it comprises carrying out said steps a) and b) for several users, generating after said step b) a preference profile for each one of said users and storing said profiles.

41. The method according to claim 40, characterized in that it comprises after having generated a series of profile preferences:

c) selecting and supplying to each of the users at least one recommendation of a multimedia element taking into consideration their relevance within said preference profiles.

42. The method according to claim 41, characterized in that said recommendation, which is at least one in number, is carried out after a corresponding request by the user.

43. The method according to claim 41, characterized in that said step a) is carried out for several certain time periods and in that said arrangement in step b) is carried out according to said number of accesses or accesses and plays for said certain time periods in the reverse order of the succession of said time periods from more to least recent.

44. The method according to claim 43, characterized in that said step b) also comprises arranging said identified multimedia elements for said user according to the time percentage that said user has maintained access or access and play to each of them as regards the total duration of each of them.

45. The method according to claim 39, characterized in that the level of importance of said second indicator is according to a predetermined parameter.

46. The method according to claim 39, characterized in that the level of importance of said second indicator is according to an adjustable parameter.

47. The method according to claim 40, characterized in that it comprises carrying out after said step b) and before said step c), a step b1) for selecting and arranging only a percentage of the multimedia elements accessed or accessed and played at least in part of each of the preference profiles, generating a preference sub-profile with said selected multimedia elements.
