Described in embodiment do not represent all implementations consistent with this disclosure.On the contrary, they be only with it is such as appended
The example of the consistent device and method of some aspects be described in detail in claims, the disclosure.
Include usually temporal information in the text message that user is received by mobile terminals such as mobile phones at present, user is reading
Usually the temporal information for including in text information is forgotten about when text information, usually brings loss to user.For example, false
If the content that user is connected to the short message of good friend is " this month No. 15 plays together ", user may see this in a russ
After short message, exact date is not noticed, user is caused to miss the time played together with good friend.
In order to avoid the above problem occurs, when mobile terminal receives text message, following any technology can be passed through
Scheme extracts temporal information from text information, then informs the user the temporal information.Alternatively, according to the temporal information
Increase event reminder events in the application of the time alarms such as the calendar in mobile terminal, to be carried in the temporal information corresponding time
Wake up user.
In the disclosure, production of grammar default first, which includes a plurality of node path, every node road
Diameter at least corresponds to a form of temporal information, and the node in production of grammar includes type of word, word, output identification and is somebody's turn to do
One or more of corresponding intermediate language form word of word, which is time word, be, for example, include it is modern, when,
Go, yesterday, it is upper one, last, one upper, bright, next, next, next, preceding, upper, last, rear, lower and under it is next etc..
Wherein, the node in production of grammar includes following three types, respectively：
The first node includes type of word and output identification, and type of word is numeric type.
For example, with reference to the production of grammar described in Fig. 1, the first node includes node 4 and section in the production of grammar
Point 11, node 4 and node 11 include numeric type and output identification@.
Second of node includes word, output identification and the corresponding intermediate language form word of the word.
For example, with reference to production of grammar shown in FIG. 1, in the production of grammar second of node include node 1,2,3,
5,6 ... etc.；For node 1, node 1 include word " when, it is modern, this ", output identification@and word " when, it is modern, this " it is corresponding
Intermediate language form word " current ".
In addition, the word can be red-letter day, i.e., may include red-letter day, output identification centre corresponding with the red-letter day in node
Linguistic form word.For example, the node includes International Labour Day, output identification@and International Labour Day corresponding intermediate language form word
For 5month 1day.
The third node includes word.
For example, with reference to production of grammar shown in FIG. 1, the third node includes node 8 in the production of grammar, is being saved
Point 8 include word " ".
In production of grammar, every node path at least indicates a form of temporal information, so if there is one
Bit string is matched with certain node path in production of grammar, then the bit string may be a temporal information.
For example, with reference to Fig. 1, for the node path being made of node 1,5,9,6,10,7, it is assumed that there are a bit string is " modern
In on June 14, in ", first word " the present " of the bit string matches with the word " the present " in node 1, second word of the bit string
Language " year " is matched with the word " year " in node 5, type of word and the number in node 9 of the third word " 6 " of the bit string
Word type matching, the 4th word " moon " in the bit string match with the word " moon " in node 6, and the in the bit string the 5th
The type of word of a word " 14 " is matched with the numeric type in node 10, the 6th in the bit string word " number " and node
Word " number " matching in 7, so the bit string is matched with the node path, which is a temporal information.
Fig. 2 is a kind of method of extracting time information shown according to an exemplary embodiment, including：
In a step 101, the text for meeting time format is captured from text message to be analyzed.
In a step 102, the temporal information in the text is obtained.
In step 103, which is converted into the time of reference format.
In the disclosure, the text of time format is met by being captured from text message, obtains the time in the text
Information, and the temporal information is converted into the time of reference format, it can so inform the user the time.Alternatively, according to this
Increase event reminder events in the application of the time alarms such as calendar of the time in mobile terminal, in time alarm user.
Fig. 3 is a kind of flow chart of the method for extracting time information shown according to an exemplary embodiment, the present embodiment
Executive agent can be that mobile terminals, this method such as mobile phone, tablet computer or PDA include：
In step 201, text message to be analyzed is segmented, obtains each word that text information includes.
In this step, text message to be analyzed can be the short text information that mobile terminal receives, for example, can be
Short message, microblogging or instant messaging information etc..
For example, mobile terminal receives a short message, it is assumed that the content of the short message is " June 14 this year ", short to this
Information is segmented, obtain word that the short message includes be respectively the present, year, 6, the moon, 14, number.
In step 202, since first word of text information, the word in text information is produced with the syntax
The node in every node path in raw formula is matched, when matching the node including the word or the type of word,
Determine the node and the word match.
In this step, since first word in text information, by the section in the word and production of grammar
Point is matched, if matching the node including the word or the node including the type of word, is shown the word and is somebody's turn to do
Node matching；It is if not obtaining the next word adjacent with the word with the node of the word match, this is next
Word is matched with the node in production of grammar.
For example, for first word " the present ", first word " the present " is matched with node shown in FIG. 1, and
Include first word " the present " with egress 1, i.e. node 1 is matched with first word " the present ".
In step 203, it if the node includes output identification intermediate language form word corresponding with the word, exports
The intermediate language form word；If the node includes output identification and numeric type, which is intermediate language form word
Language exports the word.
Since the form of the temporal information in text message is varied, possibly can not all be identified by mobile terminal, institute
In this step, various forms of temporal informations in text message are converted into unified form, which can be moved
Dynamic terminal is identified.
If the node includes numeric type, show that the word is a number, digital intermediate language form word is it
Itself, therefore can directly export.The intermediate language form word of output is used to form the information word of an intermediate language form
Symbol string.
For example, for the matched node 1 of word " the present ", node 1 include output identification@and word " the present " it is corresponding in
Between linguistic form word " current ", export the intermediate language form word " current ", the intermediate language formed at this moment
The information character string " current " of form.
Wherein, it needs in illustrating：If with not including output identification in the node of the word match, do not export any
Content.
If there is not matched word in text information, step 204 is continued to execute, that is, continues to match next word
Language.
In step 204, the corresponding each child node of adjacent with the word next word and the node is obtained, by this
Next word is matched with each child node respectively, when matching the node including the word or the type of word, is determined
The node and the word match, execute step 203.
In this step, when having matched all words in text information, step 205 is executed.
For example, the 1 corresponding child node 5,6,7 of next word " year " and node of word " the present " is obtained, by word " year "
It is matched respectively with child node 5,6,7, matching egress 5 includes word " year ", i.e. node 5 is matched with word " year "；In node 5
Including output identification@and the corresponding intermediate language form word " year " of word " year ", the intermediate language form word is exported
" year ", the information character string formed at this time are " current year ".
The 5 corresponding child node 9 of next word " 6 " and node for obtaining word " year ", by word " 6 " and child node 9
Match, matching egress 9 includes the numeric type of output identification and word " 6 ", i.e. node 9 is matched with word " 6 "；Export word
Language " 6 ", the information character string formed at this time are " current year 6 ".
The 9 corresponding child node 6 of next word " moon " and node for obtaining word " 6 ", by word " moon " and child node 6
Match, matching egress 6 includes word " moon ", i.e. node 6 is matched with word " moon "；Node 6 includes output identification@and word
" moon " corresponding intermediate language form word " month ", exports the intermediate language form word " month ", the letter formed at this time
It is " 6 month of current year " to cease character string.
The 6 corresponding child node 10 of next word " 14 " and node for obtaining word " moon ", by word " 14 " and child node
10 matchings, matching egress 10 include the numeric type of output identification and word " 14 ", i.e. node 10 and word " 14 "
Match；The word 14 is exported, the information character string formed at this time is " 6 month 14 of current year ".
The 10 corresponding child node 7 of next word " number " and node for obtaining word " 14 ", by word " number " and child node 7
Matching, matching egress 7 includes word " number ", i.e. node 7 is matched with word " number "；Node 7 includes output identification@and word
The corresponding intermediate language form word " day " of language " number ", exports the intermediate language form word " day ", the information formed at this time
Character string is " 6 month of current year, 14 day ".
In step 205, it is analyzed since first word in the information character string of composition, if the word of present analysis
Language is the corresponding intermediate voice form word of word of Fuzzy Time class, then obtains adjacent with the word of the present analysis next
A word.
For example, for information character string " 6 month 14day of current year ", from " current year 6
First word current of month 14day " starts to analyze, i.e., the word of present analysis is current, present analysis
Word current is fuzzy words when, modern and this corresponding intermediate voice form word, so obtaining the word with the present analysis
The adjacent next word year of language.
In step 206, according to current time, the word and next word of present analysis, by the word of present analysis
Language and next word are converted into the time word of reference format, and form one with the time word of the reference format obtained
Temporal information.
In this step, it according to the semanteme of the word of present analysis and the semanteme of next word, and combines current
The word of present analysis and next word are converted into the time word of reference format by the time.Can be：
If the word of present analysis be it is modern, when or this corresponding intermediate language form word, to next word
The semanteme of language is judged, if next word is year, obtains current year, and the word of present analysis is next with this
The time word that a word is converted into reference format is respectively current year and year.If next word is the moon, obtain
Current month, it is respectively current month that the word of present analysis and next word, which are converted into the time word of reference format,
And the moon.If next word is day, the date on the same day is obtained, the word of present analysis and next word are converted into
The time word of reference format is respectively date on the same day and day.
For example, the word for obtaining present analysis in step 205 is current and next word is year, current point
The word current of analysis be it is modern, when or this corresponding intermediate language form word, which is year, then obtains
Current year 2015 is taken, the time word that the word of present analysis and next word are converted into reference format is respectively to work as
Preceding time 2015 and year, i.e., 2015.
If the word of present analysis be it is bright, under, next, next or next corresponding intermediate language form word,
Then the semanteme of next word is judged, if next word is year, the next year after obtaining currently
In the time, the time word that the word of present analysis and next word are converted into reference format is respectively the time of next year
And year.If next word is the moon, obtain the month in the lower January after current month, by the word of present analysis and
The time word that next word is converted into reference format is respectively the month and the moon in lower January.If next word is
Day, then obtain the next day date on the same day, by the word of present analysis and next word be converted into reference format when
Between word be respectively next day date and day.
If the word of present analysis be it is rear, lower or under next corresponding intermediate language form word, under this
The semanteme of one word is judged, if next word is year, obtains the time in the year after next after current year, will
The time word that the word of present analysis and next word are converted into reference format is respectively the time and year for obtaining the year after next.
If next word is the moon, the month of the month after next after current month is obtained, by the word of present analysis and is somebody's turn to do
The time word that next word is converted into reference format is respectively the month and the moon for obtaining month after next.
If the word of present analysis be upper one, last, yesterday, the word for removing corresponding intermediate language form, to this
The semanteme of next word is judged, the upper time before obtaining currently, will be current if next word is year
The time word that the word of analysis and next word are converted into reference format is respectively the time and year of upper one year.If should
Next word is the moon, then the month in the upper January before current month is obtained, by the word of present analysis and next word
The time word that language is converted into reference format is respectively the month and the moon in upper January.If next word is day, obtain
The date upper one day on the same day, the time word that the word of present analysis and next word are converted into reference format are respectively
Date upper one day and day.
If the word of present analysis be before, last or upper corresponding intermediate language form word, under this
The semanteme of one word is judged, if next word is year, in the time of the previous year before obtaining currently, will be worked as
The time word that the word of preceding analysis and next word are converted into reference format is respectively the time and year of the previous year.Such as
Fruit next word is the moon, then the month of the previous moon before obtaining current month, will be under the word of present analysis and this
The time word that one word is converted into reference format is respectively the month and the moon in the preceding January.If next word is
Day, then obtain the date of the previous day on the same day, by the word of present analysis and next word be converted into reference format when
Between word be respectively the previous day date and day.
In step 207, if the word of present analysis is number, using the word of present analysis as reference format
The time word of the time word and the reference format obtained is formed a temporal information by time word.
In a step 208, it if the word of present analysis is year, the moon or day corresponding intermediate language form word, obtains
The time word for taking the corresponding reference format of intermediate language form language, by the time word and the reference format that has obtained
Time word forms a temporal information.
For example, the corresponding intermediate language form word of year, month and day is respectively year, month and day, year, month
The time word of reference format corresponding with day is respectively year, month and day, or is all "/" etc..
In step 209, if there is also non-switched words in the temporal information string, from remaining non-switched first
A word starts to analyze, and returns to step 205,207 or 208.
Wherein, if each word in the temporal information string is turned into the word of reference format, end operation,
In the temporal information as finally extracted of the temporal information that finally forms, can show the temporal information of extraction.
For example, the word for being not converted into reference format in information character string " 6 month 14day of current year " is
" 6 month 14day " is analyzed since first word 6 in non-switched word " 6 month 14day "；And current point
The word 6 of analysis be number, the time word by the word 6 of present analysis as reference format, by the time word 6 with obtained
Reference format the temporal information 2016 6 of composition one of time word 2015.
At this point, the word that the information character string " 6 month 14day of current year " is not converted into reference format is
" month 14day " is analyzed since first word month in non-switched word " month 14day "；And current point
The word month of analysis is year, the moon or day corresponding intermediate language form word, obtains month pairs of the intermediate language form word
Word moon time for the reference format answered, by 6 groups of word moon time and the time word of reference format obtained 2015
At a temporal information in June, 2016.
Later, the word which is not converted into reference format is
" 14day " is analyzed since first word 14 in non-switched word " 14day "；And the word 14 of present analysis is number
Word, the time word by the word 14 of present analysis as reference format, by the time word 14 and the reference format obtained
Time word in June, 2015 form temporal information June 14 in 2016.
Later, which is not converted into the word of reference format
For " day ", analyzed since first word day in non-switched word " day "；And the word day of present analysis be year,
The moon or day corresponding intermediate language form word, obtain the time word of the corresponding reference formats of intermediate language form word day
Language day the time word of word day time and the reference format obtained is formed into a temporal information June 14 in 2015
On June 14th, 2016.At this moment by each word in the information character string " 6 month 14day of current year "
It is converted into the time word of reference format, and temporal information on the June 14th, 2016 formed is the temporal information finally formed, and
It can show the temporal information.
