Search condition.The interest in music portrait of user may include composer, music style, movement, the performance version etc. that user likes
Information.
S320 carries out music retrieval according to determining search condition.
Illustratively, the music retrieval sentence of user's input are as follows: play classical music.User is without special retrieval mesh at this time
, it is only intended at will listen some pleasing to the ear classical music.Then can be under the restrictive condition of classical music, and the music based on user is emerging
Interesting image, such as composer, this composer classical music works, this classical music for creating of the classical music liked of user are made
The temperature of product, user (play the performance version for works of performing music the fancy grade of this classical music works and user
Philharmonic society is played by family) the information such as fancy grade, to determine classical music that user finally likes.The search condition finally obtained
It may include: the information such as the performance version of work title and each work title.Then, it is indexed by these retrieval information.
For example, for determining that user may like the musical works of " Beethoven's Ninth ", according under this works
The temperature of version and the interest in music image of user are played, determines the performance version of the musical works of this " Beethoven's Ninth "
This, such as: New York Philharmonic.Then, all movements for the Beethoven's Ninth played by New York Philharmonic are extracted.
The movement of extraction can recommend user.It can be dimension to determining musical works, by the works of musical works when recommending
Title is ranked up, such as the information such as temperature of works.One by one version will be played accordingly under the musical works of each determination
All movements play to user.
In some embodiments, if user demand includes music type, user demand can be carried out extensive.So
In addition to music type, user demand further comprises the screening conditions of limitation music type.Screening conditions may include that limitation is such
The works informations such as style, composer, creative time, the player of the musical works of music type.Therefore, above-mentioned steps S300 is mentioned
The determination process of the retrieval mode of confession, as shown in figure 5, may include step S330 and step S340, it is as follows:
S330, if user demand includes the screening conditions of music type and limitation music type, according to music type
It draws a portrait with the interest in music of user and determines search condition.The purpose of this step is general to user demand progress based on music type
Change, obtains corresponding search condition.Its extensive effect is consistent with the effect of above mentioned step S3 10, and details are not described herein.
S340 carries out music retrieval according to determining search condition and screening conditions.
The music retrieval process of the present embodiment, based on the basis of extensive demand, the works letter provided dependent on screening conditions
Breath, and be consistent with the interest in music image of user.The present embodiment can be single based on the corresponding recommendation song of screening conditions maintenance.
For example, music retrieval sentence is " classical music that broadcasting rouses oneself, the works for being sown into barpque ", then music class can be determined
Type is " classical music rouse oneself ", and screening conditions are " barpque ".For the demand of experience retrieval, for example, often occurring
Search key, different search keys (Search Requirement) can be directed to, establishing different search keys respectively, (retrieval needs
Ask) under recommendation song it is single.For example, with the Search Requirement that " classical music of barpque creation rouse oneself " includes, foundation bar
The recommendation of the classical music rouse oneself in Lip river gram period is sung single.Recommend in song list, is indexed using musical works as first term, arrange Ba Luo
The classical music rouse oneself in gram period, and safeguard in secondary entry index the respective version of each classical music.
Therefore, single according to the corresponding recommendation song of search condition and screening conditions hit determined, this is directly recommended into song list
User is recommended, by each movement under the single different editions for playing classical music one by one that put in order of song.
Fig. 6 and Fig. 7 are please referred to, Fig. 6 is the schematic diagram of the storage index structure of pop music provided in an embodiment of the present invention；
Fig. 7 is the schematic diagram provided in an embodiment of the present invention with the storage index structure that musical works is index first place.The scheme of Fig. 6 can
To be described by taking pop music as an example.The scheme of Fig. 7 can be described by taking classical music as an example.Prevalence sound explained below
The different designs of storing data structure (storage index structure) between happy and classical music.
As shown in fig. 6, the conventional each single of pop music usually has a performance version, therefore its storing data knot
Structure is simple and flat, can be formed according to " singer-album-single " and clearly inquire chain.In retrieval, the unit of user's concern
Usually single, usual " singer+song title " can navigate to specific single.It therefore, is that retrieval main body is examined with single
Rope and recommend, be currently used music retrieval side, corresponding to storage index structure be also currently used Index Design
Method.
But for multiple classical music for playing version, each performance version has multiple movements, number
It is increasingly complex compared to conventional pop music according to structure.
Illustratively, by taking composer Beethovan as an example, create musical works include it is multiple, each works have it is multiple
Version is played, i.e., is deduced by multiple such as concert performers or philharmonic society.For example, the C ditty the 5th that the sound of reading aloud/New York Philharmonic plays is handed over
It rings bent.Such classical music has very many and diverse version, and each version can correspond to arrangement determination in certain sequence
Single, such as Opus One, the second movement etc..Wherein, the quantity for the single for being included under the different editions of same works is different
Fixed identical, the part movement because part version can only deduce in this works.
In addition, the difference of classical music and conventional music is: classical music is largely external works, and the English of works
Literary fame claims usually longer, and the English name that user is difficult to directly input works carries out program request.Therefore most of works all correspond to
Chinese, so that user identifies and inquires.Meanwhile there is also alias for part works, and these alias are compared in its works
Literary fame claims more to be recognized by users, for example, " the 5th symphony of C ditty " of Beethovan is the Chinese of works, but wide
It is general to be recognized by its alias " destiny symphony ".
Based on the above analysis, the present embodiment breaks through its conventional method retrieved and recommended " with single entity ", establishes
" work title " this pseudo-entity forms " using work title as the storage index structure of the classical music of dimension " and with this
Carry out the retrieval and recommendation of music.
As described in Figure 7, it by the indexed sequential of composer, works, version and movement (single), establishes each classical music and makees
The storage index structure of product can be used when being retrieved based on this storage index structure according to different types of user demand
Corresponding retrieval mode is retrieved, as follows:
(1) retrieval of works is specified
Firstly, retrieving the works being consistent with it according to work title.Then, according to the performance version temperature of works, use
The dimensions such as family hobby, find most suitable performance version, this is recommended to play all movements under version to user, and user can be by
Whole movements under the played in order version.
(2) retrieval of works, concert performer is specified
Firstly, retrieving the works being consistent with it according to work title.Then, the performance can be matched by retrieving under this works
The performance version of family.Finally, this is played all movements under version to user, user can be played in order under the version
Whole movements.
(3) retrieval of works, movement is specified
Firstly, retrieving the works being consistent with it according to work title.Then, according to the temperature of the performance version of this works
Or the dimensions such as hobby of user, find most suitable performance version.Phase is extracted finally, playing in all single under version from this
This corresponding movement is supplied to user by the movement answered.User can play this corresponding movement.
(4) retrieval of works, concert performer, movement is specified
Firstly, retrieving the works being consistent with it according to work title.Then, according to retrieve under this works can under this works
To match the performance version of the concert performer.Corresponding movement is extracted finally, playing in all single under version from this, by this phase
The movement answered is supplied to user.User can play this corresponding movement.
Based on above-mentioned data structure and search method, the main retrieval mode of target user that classical music will be analyzed below,
To carry out carrying out the retrieval and recommendation of classical music using different retrieval modes.
(1) retrieval and recommendation of extensive demand
If user without specific purposes, is only intended at will listen some pleasing to the ear classical music, then can by the demand of user into
Row is extensive, obtains determining search condition.Then it carries out music retrieval and recommends.
Illustratively, query (query statement) are as follows: play classical music.
It is drawn a portrait according to the interest in music of user, such as: user likes which composer, the music of which style, which list
The information such as song, which concert performer, conjecture user may favorite musical works.Then, according to music temperature and user preferences etc.
Dimension filters out the favorite version of user's most probable, and putting in order according to row by musical works from the musical works of conjecture
List whole movements under the version of each musical works.Filtered list is finally recommended into user.
It in recommendation process, using musical works as dimension, is ranked up in certain sequence, and plays each music in order
The movement of respective version under works.
(2) song single retrieval and recommendation
If user on the basis of extensive demand, gives certain screening conditions, then can be determined based on extensive demand
Search condition and screening conditions, carry out music retrieval and recommend.The mode of usual screening conditions is works information.
Illustratively, query are as follows: the works for playing the classical music rouse oneself, playing barpque.
For such demand, search result depends on works information and the interest with the expression of user.Allow to protect
Card search result meets requirements above, but since data volume is excessive, is also difficult to accurately be pushed away in a large amount of works recalled
Recommend screening.Therefore, for such demand, classical music editor expert can be directed to user demand label, safeguard under different labels
Recommendation sing it is single.User demand can be determined according to the keyword that user often retrieves.In song list, it will add by dimension of works
Plus music, and screen corresponding version.In practical application, it is single to hit corresponding song according to the query statement of user.Then will
This song is singly supplied to user, and by the movement under each works of works played in order.
(3) retrieval and recommendation of precision demand
Compared to pop music, the classical music precision demand of user is more complicated, but is regarded as " work title+additional
Condition (can be default) ".
Illustratively, if query statement is " I wants to listen Beethoven's Ninth ", for the retrieval of specified works.Such as
Fruit query statement is " playing Beethoven's Ninth third movement ", for the retrieval of specified works, movement.If inquiring language
Sentence is " playing most hot Beethoven's Ninth version ", for the retrieval specified works, play version.If query statement
It is specified works, the retrieval for playing version for " Beethoven's Ninth for playing New York Philharmonic's performance ".
The implementation process of the present embodiment, which has been fully demonstrated, to be retrieved and is recommended excellent for dimension with work title (works)
