Fig. 4 is the method according to embodiments of the present invention that entity search is carried out based on entity storehouse, as shown in figure 4, according to this
The entity search method based on entity storehouse of inventive embodiments, including：
Step S402, the query from user is received, and determine the entity word frequency of the query；
Step S404, the entity word frequency based on the query are determined and query similarity highest high frequencies query；
Step S406, using above-mentioned high frequency query as entity word, relevant information search is carried out into entity storehouse.
In entity search method provided in an embodiment of the present invention, a variety of realities in the query from user are may recognize that
Body search intention, determine with the entity Word similarity highest high frequency query in query, be entity based on high frequency query
Word carries out the search of relevant information into magnanimity information and with user's request click model entity storehouse, to provide use
Family meets the search result of the demand intensity of its search intention.
In the present embodiment, the statistics for the query that can be initiated in advance user, judge that user sends out for same query
The height of the frequency risen, and a predetermined threshold value is set, and then subsequently received query is judged.If sentence
Disconnected query entity word frequency is greater than or equal to predetermined threshold value, it is determined that the query is high frequency query, now, can be straight
Connect with the query sheets as entity word, and with the entity word, relevant information search is carried out into entity storehouse.If the query's
Entity word frequency is less than predetermined threshold value, it is determined that the query is low frequency query, now, it is possible to in low frequency query
Entity is index search and low frequency query similarity highest high frequency query, and using high frequency query as entity word, to reality
Relevant information search is carried out in body storehouse.

The search that carries out relevant information is can be directly in entity storehouse from the query of user.For low frequency query, do not have in possible entity storehouse
Having directly includes low frequency query corresponding entities in itself.At this moment, it is possible to the entity in low frequency query is first analyzed, with
Entity in low frequency query is searched for index by related algorithm and low frequency query similarity highest query, is based on
The query is the search that entity word carries out relevant information into entity storehouse.The scheme provided based on the present embodiment, no matter use by oneself
The query at family belongs to high frequency query or low frequency query, can the quickly query-related information into entity storehouse, and then accurately
Provide the user Query Result corresponding with the query of user.
Preferably, include entity demand queue in the user's request click model in entity storehouse, therefore, it is determined that with it is low
, can be real to the high frequency query for having calculated that entity demand queue is established during frequency query similarity highest high frequency query
Body query inverted indexs, after identifying the entity in low frequency query, correlation is found by entity query inverted indexs
Query lists, each query in low frequency query and query row is calculated by simarank, deep learning correlation technique
Similarity, then it is that entity word carries out related letter into entity storehouse to find out to low frequency query similarity highest high frequencies query
The search of breath.
For example, if it is " Lee " to receive the query from user, by real in " Lee " this query
The frequency of " Lee " of pronouns, general term for nouns, numerals and measure words is analyzed, and determines that the query belongs to high frequency query, now can is directly arrived with " Lee "
The search of relevant information in entity storehouse.Related entities demand team has been had calculated that in user's request click model in entity storehouse
Row, at this moment can is directly presented to user as entity search result.
If it is " relevant information of Lee " to receive the query from user, by the entity word in this query
The frequency of " relevant information of Lee " is analyzed, and determines that the query belongs to low frequency query.If directly with the " correlation of Lee
Information " is entity word, possibly accurately can not obtain relevant information directly from entity storehouse.Now, can be will calculate
The high frequency query of entity demand queue establishes entity query inverted indexs.
Inverted index comes to be needed to be recorded to search according to the value of attribute in practical application, each single item in this concordance list
All include the address of a property value and each record with the property value.Due to not being to determine property value by recording, but
The position of record, thus referred to as inverted index (invertedindex) are determined by property value.Entity query inverted indexs are
Entity corresponding with high frequency query will be obtained based on the high frequency query having calculated that, by real corresponding to high frequency query
Body can link to high frequency query.When the query received is the relevant information of Lee " when ", may recognize that in the query
Entity be " Lee ", by query inverted indexs find correlation query lists, pass through simrank or depth study
Correlation technique can is by the similarity of each query in " relevant information of Lee " and query lists, if calculating " Lee
Similarity highest query in the relevant information of certain " and query lists, or similarity are more than the query of predetermined threshold value and are
" Lee ", then it is the search that entity word carries out relevant information into entity storehouse with " Lee ", that is to say, that the query " phases of Lee
Pass information " inherits " Lee " this high frequency query entity demand queue.
It should be noted that in practical application, above-mentioned all optional embodiments can be any group by the way of combining
Close, form the alternative embodiment of the present invention, this is no longer going to repeat them.
