Most poetry works can also be cited story ancient books and records and practical work background, make poetry works under the appearance of graceful text, contain
There is deeper emotional expression.The characteristics of based on poem text, so that it can not pass through merely surface text in semantic analysis
Word determines the true semanteme of poem, and for part poetry works, meaning expression is excessively obscure mild and roundabout, passes through text merely
Analysis is difficult to obtain the real meaning of poetry works.Such as the Tang Dynasty poet's Li Shangyin《Untitled brocade plucked instrument》In verse " Zhuan Shengxiao
Butterfly is confused in dream, hopes Supreme Being's desire for love support cuckoo.Deep blue sea month jewel has tear, the warm beautiful raw cigarette in Lantian day." four allusions are used in conjunction, express its sorrow
Hurt the feelings of miss, this obscure affective content is difficult simple to find out from word content.Therefore it in poem retrieving, answers
The semanteme of poetry works is analyzed, not only to analyze poem textual content, but also the expression that textual content is hidden behind is thought
Think that also there is important reference significance.
In order in poem retrieving, take into account word content and express thoughts, when analyzing poem source text, also to lead to
The analysis to the corresponding appreciation text of poem is crossed, expressing thoughts for poetry works is obtained.Therefore the poem money mentioned in the application

The attribute information of poem be refer to characterization poem and poem related content information, including indispensable attributes information and
Non necessary attribute information, indispensable attributes information are the information that can be directly determined according to poem original text, such as：Title, original text, work
Person, theme, emotion etc., indispensable attributes information are the occurrences shown in vocabulary content, such as：Indicate the vocabulary " drink of title
Wine ", etc.；Show the vocabulary " picking chrysanthemum by the east fence down " etc. of original text；Show the vocabulary " TAO Yuan-ming " etc. of author.Non necessary attribute information is
Refer to the other information in addition to indispensable attributes information, poem resource cannot clearly be judged by non necessary attribute information, but can be true
Determine the wish that user has retrieval poem resource, shows as：Creative time, poem type, poem type of poem etc..For example,
" a first poem of four lines " can be understood as non necessary attribute poem type (poem of four lines), lack indispensable attributes information.As it can be seen that user is in poem
In retrieving, to obtain the poem resource for meeting self-demand, in the text retrieved, it is necessary to necessary comprising at least one
Attribute information.But user may have half knowledge for desired poem, cannot correctly describe the attribute of poem before retrieving
Information makes to lack indispensable attributes information in the text of input.
By way of taking turns session, guidance user correctly enters in text input comprising indispensable attributes information the application more
Content of text specifically include following implementation to retrieve the poem resource for being more in line with user search wish：
Embodiment one
It is a kind of flow diagram of poem search method based on semantic analysis referring to Fig. 1.
Poem search method provided by the present application based on semantic analysis, including：
S101：Obtain the session text of user's input；
S102：According to the session content of text, judge whether containing indispensable attributes information in the session text, it is described
Indispensable attributes information includes vocabulary corresponding with poem textual content and/or the vocabulary for describing poem；
S103：If not containing indispensable attributes information, display reminding information in the session text, and obtain user again
The supplemental text of input, and according to the supplemental text content, determine indispensable attributes information, the prompt information includes inquiry must
Attribute information and prompt is wanted to input information again；
S104：Vocabulary content, which is corresponded to, according to the indispensable attributes information determines range of search；
S105：The poem resource vocabulary corresponding with the indispensable attributes information in the range of search is matched, determines retrieval
As a result, simultaneously feedback searching result.
For step S101, user inputs session text by the search interface of terminal device, and determines operation executing
Afterwards, the session text is sent to server by terminal device, server receives the session text from terminal device, and right
Session text is analyzed and processed.The terminal of the application refers to text input and display function and communicates with server foundation
The electronic equipment of network connection, such as computer, mobile phone, tablet computer, electronic reader.
For step S102, after server receives the session text, server judges according to session content of text
Whether contain indispensable attributes information in the session text, specifically, after server receives the session text, to the meeting
Words text is split by vocabulary, obtains whole lexical informations in session text, then by analysis part of speech and word content, go
Except the not modal particle of physical meaning and the word unrelated with poem resource.For example, the session content of text of user's input is
The original text of plucked string instrument with a fretted fingerboard basketry row " Wish i knew what is ", participle tool is split session text, and example is as follows：
I/thinking/know/plucked string instrument with a fretted fingerboard basketry row// original text/be/what；
By analysis the vocabulary after segmentation is analyzed, it is known that, " I ", " thinking ", " knowing ", " ", "Yes", " what "
It is all the word unrelated with poem resource, therefore server only retains " plucked string instrument with a fretted fingerboard basketry row " and " original text " the two vocabulary in retrieval.
In the application, the indispensable attributes information includes vocabulary corresponding with poem textual content and/or the vocabulary for describing poem.It is above-mentioned
Example, " plucked string instrument with a fretted fingerboard basketry row " are the titles of poem, are that can characterize the indispensable attributes information of poem content, and " original text " can although being
It indicates poem or relevant vocabulary, but cannot indicate the particular content of poem, therefore be a kind of non necessary attribute information.It needs
Bright, " original text " only indicates the vocabulary content of user conversation text herein, no with " original text " in above-mentioned indispensable attributes information
It is same concept.That is, " original text " only indicates " original text " the two words herein, and " original text " in above-mentioned indispensable attributes information is
Indicate corresponding textual content in poem resource, such as " waterside Yangjiang head night sees a visitor out, and maple leaf reed autumn is rustle ".Therefore, in order to distinguish
Similar concept, can be equipped with a kind of non necessary attribute information " mode ", including indicate vocabulary content of text, such as " original text ",
" context " etc., and will be the value that " original text " regards as the non necessary attribute information herein.
Whether server judges containing indispensable attributes information in the session content of text in the present embodiment, if
Include indispensable attributes information in the session text, executes step S104；If not including indispensable attributes in the session text
Information executes step S103.
For step S103, when lacking indispensable attributes information in the session text, server can not be according to input
Content of text judges the retrieval wish of user, at this point, server sends prompt information to terminal, terminal will be prompted to information to user
It has been shown that, user can input again according to prompt information.In the present embodiment, prompt information is presented to use in the form of session
The interaction with user is realized at family, such as：
The session content of text of user's input is " carrying out a first ancient poetry ", after segmenting to this session text, can be obtained
It arrives：
" carrying out/mono- head/ancient poetry "
Wherein, " next " and " one is first " is the vocabulary unrelated with poem resource, and " ancient poetry " cannot specifically determine specifically poem
Therefore word resource content judges not containing the indispensable attributes information in the session text, at this time display reminding information, such as
" range that you retrieve is excessive, please re-enter keyword ", prompts user to input supplemental text again.Further, described to mention
Show that information can be generated according to the content of session text, the session text inputted as far as possible close to user on diction, and
Including with sample text similar in prompt information content, such as：According to the participle for inputting session text " come a first ancient poetry "
Content, it is that " you want which type of first ancient poetry carried out that corresponding prompt information content, which can be generated, in " next " and " one is first "？Also,
While display reminding information, stich can also be pushed at random or one head of push retrieves the high poem of frequency, while being shown
Example text sheet will include indispensable attributes information in sample text, further inquiry to retrieve the author of poem resource, title, emotion,
Theme or part verse content etc., such as while display " you want which type of first ancient poetry carried out ", also display is " for example, one
First sad ancient poetry " inputs correct supplemental text with prompt information and sample text guidance user.
After user re-enters supplemental text, server judges whether believe containing indispensable attributes in supplemental text again
Breath executes step S104 if containing indispensable attributes information, if not containing indispensable attributes information still, executes step again
S103, until the supplemental text of user's input includes indispensable attributes information.If user is after receiving prompt information, without again
Supplemental information is inputted, then in the present embodiment, obtains retrieval temperature highest and is inputted in session text similar in content with user
Correspondence vocabulary of the vocabulary as indispensable attributes information, continues to retrieve, but when exporting search result, should give display, example
As " everybody is looking for ' one first sad ancient poetry ' ".
For step S104, after containing indispensable attributes information in judging the session text or the supplemental text, root
Vocabulary, which is corresponded to, according to the indispensable attributes information determines range of search.In the present embodiment, the range of search refers to and is judged as must
The corresponding poem resource collection of the vocabulary of attribute information is wanted, i.e., in range of search, comprising corresponding with the indispensable attributes information
The poem resource that vocabulary is consistent.Further, range of search can be some classification in poem resource database, can also be with
It is the poem resource that vocabulary corresponding with the indispensable attributes information is consistent in Internet resources.
For step S105, after determining range of search, the poem resource in the range of search and institute are further matched
It states indispensable attributes information and corresponds to vocabulary, determine that the poem resource for corresponding to vocabulary comprising the indispensable attributes information in range of search is
Search result, and feedback searching result.In the retrieving of poem resource, the session text difference of user's input is larger.Have
When can express retrieval wish session content of text it is more ambiguous so that meeting the search result quantity of the session text not only
One, it, can wherein the highest single poem of retrieval temperature provides according to selection for the search result of multiple quantity in the present embodiment
Source according to pre-defined rule as a result, can also such as retrieve temperature, be ranked up to all search results, and show to user.
For example, the session content of text of user's input is " Li Shangyin is untitled ", the content of session text by analysis can
Know, " Li Shangyin " is author information, and " untitled " is heading message, and the two is all indispensable attributes information, and in the database, author
For " Li Shangyin ", entitled " untitled " poem resource is totally 15 first, wherein《Untitled difficulty Hard To Say Goodbye when meeting each other》Retrieval temperature
Highest, therefore search result is determined as《Untitled difficulty Hard To Say Goodbye when meeting each other》, and the original text of the poem, description and appreciation etc. are believed
Breath feeds back to user terminal.
Embodiment two
In the present embodiment, as shown in Fig. 2, in order to increase the accuracy rate to poem resource retrieval, to be provided more for user
Add search result abundant, present invention also provides the poem resources banks for retrieving poem resource, to avoid network data
It is excessively lengthy and jumbled, nonstandard problem of classifying.Correspondingly, the application is further comprising the steps of before retrieving to poem resource：
S201：Obtain poem text information, the poem text information include poem source text, poem describe text with
And poem appreciation text；
S202：Determine that poem attribute information, the attribute information are that text information is corresponding according to the poem text information
Feature lexical set；
S203：Classified according to the poem attribute information to the poem text information, and determines each classification
Tag along sort；
S204：Poem resources bank is constructed according to sorted poem text.
In the present embodiment, poem text information is obtained first, wherein the acquisition source of poem text information, which can be, to be passed through
In server end by manual entry, it is also possible to obtain by the calling to Internet resources and automatic identification poem.Calling net
In network resource process, the source text that related poem is stated in resource, poem description should be determined by the analysis to Internet resources
Text and poem appreciation text.Due to may only include one of above-mentioned text in single network resource, in order to advise
Model resources bank is to classify, and after analyzing Internet resources, should continue to adjust in a network according to the relevant information of poem resource
With other Internet resources, the text completion that will lack.
After getting poem text information, the attribute information of poem is determined according to poem text information.Poem is provided
The source text in source, attribute information, that is, textual content.For poem source text, it should the original text with whole first poem be according to
According to, but when being judged according to this, data processing amount can be greatly increased and reduce the richness of search result.Therefore, it is carrying out
When retrieval, it should using the vocabulary in poem source text as the corresponding attribute information of text information, at this point, attribute information is original
The set of all feature vocabulary in text.Text is described for poem, it should expression poem resource is determined in the description text
Feature Words, such as indicate the name vocabulary of author information and the pseudonym of corresponding author, word and number grade vocabulary；Indicate theme
Vocabulary；Indicate that poem resource is included or the vocabulary in source etc..For poem appreciation text, the main creation according to poem is carried on the back
Scape, e.g., the Turmoil of Anshi in Tang Dynasty makes tranquil the Feature Words as expression poem attribute such as change of health etc. or author's life resume.
In the present embodiment, after determining poem attribute information, classification processing is carried out to poem resource, the foundation of classification can be from
Multiple angles are repeatedly judged.In the application, for single poem resource, multiple classification can be belonged to, for example,《Water tune
What time song head bright moon has》Poem resource, belonging to classification can be：Author is the classification of Soviet Union's horizontal bar in the front of a carriage used as an armrest, and creative time is north
The classification of Song expresses thoughts as the classification etc. of miss.In the present embodiment, the tag along sort of each classification should be somebody's turn to do for expression
The feature vocabulary of classification.Such as author is the classification of Soviet Union's horizontal bar in the front of a carriage used as an armrest, tag along sort is " Soviet Union's horizontal bar in the front of a carriage used as an armrest ", in order to correctly judge poem resource
Classify, should also include lexical set identical with feature lexical meaning in the tag along sort.For example, tag along sort is " Soviet Union
The classification of the horizontal bar in the front of a carriage used as an armrest " should also include that can express other vocabulary that author is " Soviet Union's horizontal bar in the front of a carriage used as an armrest ", such as " Soviet Union and Eastern Europe slope ", " perillaseed is looked forward or upwards ", " Su Xian "
Deng.Poem resources bank is finally constructed according to sorted poem text, and poem resources bank is saved.
In addition, the classification system of poem resource can be constructed when classifying to poem resource, i.e., according to the poem
Attribute information constructs classification system model.Can also construct disaggregated model in advance, then by classification algorithm training poem resource from
And the classification of poem resource is obtained, specific sorting algorithm is it is known in the art that repeating no more.
Embodiment three
As shown in figure 3, the difference of the present embodiment and above-described embodiment is, according to the session content of text, institute is judged
It states whether containing indispensable attributes information in session text, the indispensable attributes information includes vocabulary corresponding with poem textual content
And/or the step of describing the vocabulary of poem, including：
S301：Extract the keyword in the session text；
S302：Obtain the corresponding preset corpus of the indispensable attributes information, and by the keyword and the preset corpus
It is matched, the preset corpus includes preset vocabulary corresponding with poem textual content in the database, and/or description
The vocabulary of poem；
S303：According to the matching result, determining keyword corresponding with the preset corpus is indispensable attributes information.
In existing retrieving, usually by the vocabulary in session text, directly with the whole in poem resources bank
Text data is matched, and the data call amount of this matching process is huge, can reduce recall precision, and for poem text
Information and keyword carry out in matching process, since there are appreciation texts, it is also possible to will not be the vocabulary mistakes of indispensable attributes information
Keyword is thought, so that the search result for not meeting user intention is fed back to user.
In order to avoid the above problem, in the present embodiment, the keyword extracted in the session text is first passed through, then will be described
Keyword preset corpus corresponding with the indispensable attributes information is matched, thus judge extract keyword in whether include
Indispensable attributes information.By the way that preset corpus is arranged, keyword is matched with the text in preset corpus, that is, can determine user
It whether include indispensable attributes information in the session text of input.Preset corpus, which can be, indicates that the tag along sort of each classification is constituted
Set, and updated with the update of poem resources bank.By the matching of preset corpus and keyword relative to poem
Resource, which directly carries out matching, can greatly reduce data call amount, improve recall precision, while also avoid not being necessary
The vocabulary of attribute information is mistakenly considered indispensable attributes information.
Since single poem resource can belong to multiple classification, determination poem resource in order to be more accurate,
In retrieving, user can be prompted to input the indispensable attributes information of multiple determining poem resources by way of taking turns session more.
Vocabulary is corresponded to by each indispensable attributes information and determines classification, and then the poem for belonging to multiple classification is determined by multiple attribute informations
Word resource, as search result.Further, when corresponding including multiple indispensable attributes information in the session text of user's input
