Optionally, in first database, the target word " Nan Shannan " of the word in target text is searched, is obtained To the target word " Nan Shannan/NM " for having markup information, then " Nan Shannan/NM " is determined as to the participle of target sheet.Word " south The field that the markup information " NM " in mountain south " can be used for marking belonging to it is music field, then may further determine that " South Mountain South " is the song " Nan Shannan " in music field, rather than the address " Nan Shannan " in geographic territory.
Optionally, the participle of the target text of the embodiment can also have part-of-speech tagging, for example, having noun n, verb The part-of-speech taggings such as v.
Optionally, when which searches target word in first database, pass through Tire tree-efficient storage retrieval knot Structure searches target word, to greatly improve the search efficiency to target word.Finally it is re-introduced into even numbers group Tire tree Structure advanced optimizes the memory footprint of general T ire tree.Wherein, Tire tree is a kind of tree structure, because it is dictionary A kind of storage mode, therefore be called dictionary tree.Each of dictionary word shows as one in Tire tree and points out from root knot The path of hair, it is exactly a Tire tree that the point on the side of path, which links up,；Even numbers group Trie (Double-ArrayTrie) is Trie One of tree is simple and effectively realizes, is made of two integer arrays, is looked into even numbers group dictionary tree for each participle The mark of inquiry.
Step S408 determines that the target of participle is semantic according to target markup information.
In the technical solution that the application above-mentioned steps S408 is provided, will there is target markup information in first database Target word, be determined as after the participle of target text, determine that the target of participle is semantic according to target markup information.
The target markup information of the embodiment is used to indicate field belonging to target word, can be according to target markup information Determine that the target of participle is semantic, for example, target word is " Nan Shannan ", there are two types of meanings in the South Mountain south, and one is song " South Mountain South ", another kind is geographical location " Nan Shannan ".It, can be according to " NM " when the target markup information of target word is " NM " Determine that " Nan Shannan " belongs to the word in music field, then the target semanteme for segmenting " Nan Shannan/NM " is song " Nan Shannan "；When When the target markup information of target word is " NP ", the word in geographic territory can be belonged to according to " NP " determination " Nan Shannan " Language, then the target semanteme for segmenting " Nan Shannan/NP " is geographical location " Nan Shannan ".
Step S410, it is semantic according to the target of participle, determine the semanteme of target text.
In the technical solution that the application above-mentioned steps S410 is provided, target text is being determined according to target markup information After the target of participle is semantic, the target according to the participle of target text is semantic, determines the semanteme of target text, and then execute mesh Mark order indicated by the semanteme of text.For example, it is semantic according to the target of " navigation ", " arriving ", " Shenzhen University ", determine target text The semanteme of this " navigating to Shenzhen University " is to navigate to Shenzhen University, and then execute navigation command, realizes navigation purposes.
S402 to step S410 through the above steps obtains the target text identified to target voice；? In one database, the target word in the word of target text is searched, wherein first database has markup information for storing Word, markup information is used to indicate field belonging to the word with markup information；Target is found in first database In the case where word, with the target word of target markup information, the participle of target text will be determined as in first database, In, markup information includes target markup information, and target markup information is used to indicate field belonging to target word；According to target mark It infuses information and determines that the target of participle is semantic；It is semantic according to the target of participle, determine the semanteme of target text.Due to target text Participle determines the semanteme of target text, has reached guarantee target text with the markup information for marking participle fields The semantic purpose correctly identified has reached the technical effect for improving the efficiency of semantics recognition, and then has solved in the related technology There is technical issues that semantics recognition.
As an alternative embodiment, step S404 is searched in the word of target text in first database Target word includes: at least one word to be selected from the word of target text, and at least one word is determined as target word Language；Target word is searched in first database.
In this embodiment, the word of target text includes multiple words, for example, target text is " it is too soft to play the heart ", Then " needing to play the heart too soft " may include multiple words, for example, including " needs ", " broadcasting ", " heart is too soft " three words.From At least one word is selected in the word of target text, be can choose all words in target text, also be can choose target A word in multiple words of text, also can choose more than two words in the word of target text, for example, mesh Word " needs ", " broadcasting ", " heart is too soft " three words in text " needing to play the heart too soft " are marked, due to " needs ", " are broadcast Put " for verb, semanteme is specific, thus can only select " heart is too soft " from " needs ", " broadcastings ", " heart is too soft " this is a Word.At least one word selected from target text is determined as to the target word of target text, for example, by the word " heart It is too soft " it is determined as the target word of target text " needing to play the heart too soft ".At least one is selected in the word from target text A word, and after at least one word is determined as target word, target word is searched in first database, for example, the One database includes the data in music field, " heart is too soft " is searched in first database, if looked into first database " heart is too soft " is found, then the participle by " heart too soft/NM " with markup information as target text " needing to play the heart too soft ".
As an alternative embodiment, searching the target word in the word of target text in first database Before, this method further include: from the word with markup information obtained in server in multiple fields, wherein have mark The word of information marks above-mentioned markup information on the server；Word with markup information is imported in first database.
In this embodiment, first database can be used for storing the word with markup information in multiple fields, clothes Word in the available multiple fields of device of being engaged in, and the word in multiple fields is labeled, make the word in each field All there is markup information.Optionally, multiple fields can for operation excavation applications, music field, map field, communication field, School field etc., no limitations are hereby intended, the markup information on automatic marking on the server of the word in multiple fields, than Such as, server adds markup information to the target position of each word, can anterior locations to each word or back position Addition markup information is set, for example, " Nan Shannan/NM " is obtained to addition markup information " NM " behind word " Nan Shannan ", thus Realize the automatic marking to word.
From in server obtain multiple fields in the word with markup information after, by the word with markup information Language imports in first database, for example, importing the word with markup information runed in excavation applications to first database, leading Enter the word with markup information in map field, import the word for listening content with markup information in music field, And the word with local address book in importing communication field, phase is interacted with vehicle-mounted voice in addition to this it is possible to import The word etc. in other fields closed, no limitations are hereby intended.
As an alternative embodiment, step S404 is searched in the word of target text in first database Target word includes: to search the target word in the word of target text in the first database with dictionary tree construction, In, the word with markup information in multiple fields is distributed in the mulitpath of dictionary tree construction.
In this embodiment, dictionary tree is a kind of tree structure, is a kind of storage mode of dictionary.Each of dictionary Word shows as the path from root node in dictionary tree, and it is exactly a dictionary tree that the point on the side of path, which links up,. In the first database with dictionary tree construction, the target word in the word of target text, the word in dictionary tree are searched There is common prefix in dictionary tree, common prefix is stored in shared memory space, that is, the common prefix of dictionary data Can be with the communal space, magnanimity dictionary data recall precision is unrelated with dictionary item number, and ratio establishes Hash (Hash) table in this way, past from a left side Splicing word goes the scheme searched in Hash table more to save space again afterwards.There is mark in the multiple fields of the embodiment The word of information is distributed in the mulitpath of dictionary tree construction, so as to search participle in the path of dictionary tree.
Optionally, the dictionary tree of embodiment includes even numbers group dictionary tree, and even numbers group dictionary tree can subtract to a certain extent The waste of few memory.Even numbers group dictionary tree includes that two shaping arrays can be used to indicate that for example, one is array base [] The array of the base address of descendant node, its value are the base value of state transfer, another is check [], for identifying forerunner's section The address of point, is equivalent to check value, for checking that the state whether there is, the corresponding word of the state.If array index is I, each word can be indicated by the subscript of even numbers group.The each word of even numbers group is inquired in even numbers group dictionary tree Mark, if base [i], check [i] are 0, then it represents that the position, if base [i] is negative value, indicates the state to be empty To terminate state (i.e. word), check [i] indicates the previous state of the state.In the first number with even numbers group dictionary tree construction According to the target word in library, searched in the word of target text, query time of each word in even numbers group dictionary tree and every The length of a word is related, for example, when word length more in short-term, query time is shorter, when the length of word is longer, inquires Time is longer.
The even numbers group dictionary tree of the embodiment can be constructed as a kind of dynamic retrieval method, to solve to be inserted into and delete institute There are the problem of.For example, when being inserted into new base value, it is only necessary to traverse dummy status.One can be constructed to all dummy status A sequence only needs to scan the sequence when determining base value.The useless node generated when for deleting leaf node can incite somebody to action They are set to sky, so that being reused when being inserted into neologisms, after deleting a state, array end is likely to occur continuous Dummy status is also directly to delete, to advanced optimize memory footprint.

As an alternative embodiment, updated with markup information in multiple fields from obtaining in server Word include: from server obtain multiple fields in the modified word with markup information, wherein in first database The word with markup information before being stored with modification corresponding with the modified word with markup information, updated tool The word for having markup information includes the modified word with markup information；Adding into first database updated has The word of markup information, obtaining updated first database includes: to have mark before the modification that will be stored in first database The word for infusing information, replaces with the modified word with markup information, obtains updated first database.
In this embodiment, the data in different field will be updated, and the data of update can be in different field to original The data that data are modified.When from the updated word with markup information in multiple fields is obtained in server, from The modified word with markup information in multiple fields is obtained in server, and after being stored with and modifying in first database The corresponding modification of the word with markup information before the word with markup information, for example, it is modified have mark letter The word of breath is " Nan Shannan/NM ", and the word with markup information before modifying is " Nan Shannan/NP ".From server After obtaining the word with markup information increased newly in multiple fields, will there is mark before the modification stored in first database The word for infusing information, replaces with the modified word with markup information, obtains updated first database, for example, will The word " Nan Shannan/NP " with markup information before the modification stored in first database replaces with modified with mark The word " Nan Shannan/NM " for infusing information, so that updated first database is obtained, so that the content in first database It is adapted to the update of word in multiple fields, guarantees that the word in subsequent first database can be with the word in target text Correct matching, improves the accuracy of semantics recognition.
As an alternative embodiment, step S404 is searched in the word of target text in first database Target word includes: a variety of division results for obtaining and being divided to target text, wherein every kind of division result is by target The word of text forms；The target division result for meeting goal rule is determined in a variety of division results；In first database, Search the target word in the word of target division result.
In this embodiment, target text is divided, obtains a variety of division results, it can be by decision model to mesh Mark text is divided.Goal rule is imported to the decision model, which is the rule divided to target text. The a variety of division results divided to target text are obtained, for example, target text is " it is too soft to play the heart ", can be based on Three adjacent words of dictionary cutting " play the heart too soft ", obtain a variety of division results " broadcasting _ heart _ too soft ", " broadcasting _ heart _ too ", " broadcast _ trust _ too soft ", " broadcast _ trust _ too ", " broadcast _ put _ heart ", every kind of division result is made of the word of target text.It is obtaining It takes after carrying out a variety of division results that word segmentation processing obtains to target text, is determined from a variety of division results and meet target rule Target division result then, for example, determining that length is maximum, average length is maximum, word variation is minimum, single from a variety of division results The division result for meeting the goal rule is determined as target division result, and then obtained by the highest division result of free morpheme degree It takes at least one of the target division result to segment, the markup information of each participle is determined in first database, according to mark Note information determines that target of each participle in target domain is semantic, finally semantic according to the target of each participle, determines target The semanteme of text, to reach the technical effect for improving the efficiency of semantics recognition.
As an alternative embodiment, determining the target division result for meeting goal rule in a variety of division results It include: to obtain the sum of length of all words in every kind of division result in a variety of division results and determine all words Maximum first division result of the sum of length, wherein the quantity of the first division result is the first quantity；It is 1 in the first quantity In the case of, the first division result is determined as to meet the target division result of goal rule；The case where the first quantity is not 1 Under, in the first division result of the first quantity, the average length of all words in every kind of first division result of acquisition is simultaneously true Maximum second division result of average length of fixed all words, wherein the quantity of the second division result is the second quantity, second Quantity is less than or equal to the first quantity；In the case where the second quantity is 1, it is determined as the second division result to meet goal rule Target division result；In the case where the second quantity is not 1, in the second division result of the second quantity, every kind second is obtained The long amplitude of variation of word of all words in division result simultaneously determines that the smallest third of the long amplitude of variation of word of all words divides As a result, wherein the quantity of third division result is third quantity, and third quantity is less than or equal to the second quantity；It is 1 in third quantity In the case where, third division result is determined as to meet the target division result of goal rule；The case where third quantity is not 1 Under, in the third division result of third quantity, obtain the free morpheme degree, simultaneously of all words in every kind of third division result Determining highest 4th division result of the free morpheme degree of all words, wherein the quantity of the 4th division result is the 4th quantity, 4th quantity is less than or equal to third quantity, and free morpheme degree is used to indicate word and morpheme constitutes the probability of new word；? In the case that four quantity are 1, the 4th division result is determined as to meet the target division result of goal rule.
In this embodiment, when determination meets the target division result of goal rule from a variety of division results, more In kind division result, obtains the sum of length of all words in every kind of division result and determine the sum of the length of all words Maximum first division result, the quantity of the first division result are the first quantity；In the case where the first quantity is 1, by first Division result is determined as meeting the target division result of goal rule.
For example, in a variety of division results, the sum of the length of all words in every kind of division result is obtained, than Such as, a variety of division results be " broadcasting _ heart _ too soft ", " broadcasting _ heart _ too ", " broadcast _ trust _ too soft ", " broadcast _ trust _ too ", " broadcast _ Put _ the heart ", wherein " broadcasting _ heart _ too soft " has 3 words " broadcasting ", " heart ", " too soft ", and the length summation of this 3 words is 5, " broadcasting _ heart _ too " there are 3 words " broadcasting ", " heart ", " too ", the length summation of this 3 words is 4, " broadcast _ trust _ too soft " have 3 words " broadcasting ", " trusting ", " too soft ", the length summation of this 3 words are 5, " broadcast _ trust _ too " have 3 words " broadcasting ", " trusting ", " too ", the length summation of this 3 words are 4, and " broadcasting _ put _ heart " has 3 words " broadcasting ", " putting ", " hearts ", this 3 points The length summation of word is 3.Determine maximum first division result of the sum of length of all words, due to division result " play _ The heart _ too soft " and " broadcast _ trusts _ it is too soft " length be 5, thus above-mentioned first division result be " broadcasting _ heart _ too soft " and " broadcast _ trust _ too soft ", the first quantity of first division result is 2, is not 1, can't determine target division result.
In the case where the first quantity is not 1, in the first division result of the first quantity, every kind first division knot is obtained The average length of all words in fruit and maximum second division result of average length for determining all words, wherein second The quantity of division result is the second quantity, and the second quantity is less than or equal to the first quantity；In the case where the second quantity is 1, by the Two division results are determined as meeting the target division result of goal rule.
For example, in the first division result of the first quantity, all participles in every kind of first division result are obtained Average length, for example, " broadcasting _ heart _ too soft " has 3 participles, the average length of each participle is 1.667 (5/3= 1.667), " broadcast _ trust _ too soft " has 3 participles, and the average length of each participle is 1.667 (5/3=1.667), " play _ The heart _ too soft " and " broadcast _ trusts _ it is too soft " average length be 1.667, thus, " broadcasting _ heart _ too soft " and " broadcast _ trust _ too It is soft " it is the second division result, the second quantity is 2, is not 1, can't determine target division result.
In the case where the second quantity is not 1, in the second division result of the second quantity, every kind second division knot is obtained The long amplitude of variation of word of all words in fruit and the smallest third division result of the long amplitude of variation of word for determining all words, Wherein, the quantity of third division result is third quantity, and third quantity is less than or equal to the second quantity；The feelings for being 1 in third quantity Under condition, third division result is determined as to meet the target division result of goal rule.
For example, in the second division result of the second quantity, all participles in every kind of second division result are obtained The long amplitude of variation of word, the long amplitude of variation of the word are the long standard deviation of the word of participle.For the second division result " broadcasting _ heart _ too soft ", There are 3 participles " broadcasting ", " heart ", " too soft ", the long amplitude of variation of word is For the second division result " broadcast _ trust _ too soft ", there are 3 participles " broadcasting ", " trusting ", " too soft ", the long amplitude of variation of word isDue to the second division result " broadcasting _ heart _ too soft " and " broadcast _ Trust _ it is too soft " the long amplitude of variation of word be 0.577, the smallest third division result of the long amplitude of variation of the word of all participles is " broadcasting _ heart _ too soft " and " broadcast _ trust _ too soft ", the third quantity of third division result is 2, is not 1, can't determine mesh Mark division result.
In the case where third quantity is not 1, in the third division result of third quantity, obtains every kind of third and divide knot The free morpheme degree of all words in fruit and highest 4th division result of free morpheme degree for determining all words, wherein The quantity of 4th division result is the 4th quantity, and the 4th quantity is less than or equal to third quantity, and free morpheme degree is used to indicate word The probability of new word is constituted with morpheme；In the case where the 4th quantity is 1, the 4th division result is determined as to meet target rule Target division result then.
For example, in the third division result of third quantity, all participles in every kind of third division result are obtained Free morpheme degree, for example, obtaining third division result respectively is " broadcasting _ heart _ too soft " and the freedom of " broadcast _ trust _ too soft " Morpheme degree, free morpheme be can separate words, the morpheme of word can be also combined into other morpheme, free morpheme degree is used for It indicates that participle constitutes the probability of word, can be indicated with natural logrithm.Wherein, third division result is the " broadcasting _ heart _ too It is soft " length be 5, average length 1.667, the long amplitude of variation of word be 0.577, natural logrithm calculated result be 13.0072, Third division result be the length of " broadcast _ trust _ too soft " be 5, average length 1.667, the long amplitude of variation of word is 0.577, Natural logrithm calculated result is 10.1699.Thus third division result be " broadcasting _ heart _ too soft " individual character free morpheme degree most Height, is the 4th division result, and quantity 1 then is determined as the 4th division result " broadcasting _ heart _ too soft " to meet goal rule Target division result, and then obtain at least one of target division result participle, determine the target semanteme number of each participle According to, it is finally semantic according to the target of each participle, the semanteme of target text is determined, to reach the efficiency for improving semantics recognition Technical effect.
Optionally, if the 4th quantity is not 1, a kind of draw can be randomly choosed from the 4th division result of the 4th quantity Divide result as target division result, and then in first database, search the target word in the word of target division result, In the case where finding target word in first database, will there is the target word of target markup information in first database Language is determined as the participle of target text, determines that the target of participle is semantic according to target markup information, according to the target language of participle Justice determines the semanteme of target text.If the semanteme inaccuracy of target text, user can feed back this time language to target text The opinion for the result that justice is identified, and the correct semanteme thought.The data of user feedback are obtained, and on server Report, product and operation personnel can limit the division result that terminal is made according to the data fed back on line, to reduce Next time selects a kind of probability of the above-mentioned division result being randomly selected as target division result.
