In the embodiment of the present invention, the word for the event that event keyword can be used for indicating to reflect that needs are completed, When creating prompting, the event content for establishing daily prompting;Trigger condition keyword is associated with the event keyword, can It is carried out for indicating the event under what conditions, when creating prompting, the trigger condition for establishing daily prompting, In general, the trigger condition keyword can specifically include time-critical word with time attribute and/or with geographical location The geographical keyword of attribute.
In one preferred embodiment of the invention, event keyword is extracted described in step S100 from content of text, And the step of associated with event keyword trigger condition keyword, it can specifically include:
Step S110, trigger condition keyword of the extraction with event correlation from content of text;The trigger condition Keyword can specifically include time-critical word and/or geographical keyword;
In one preferred embodiment of the invention, the touching with event correlation of the extraction from the content of text The step of sending out condition keyword, can specifically include:
Step S111, matching inquiry is carried out in time-critical character library, with obtain with the content of text in include when Between keyword;The time-critical character library is to establish to obtain according to temporal expressions corpus;
In practical applications, text can be expressed with acquisition time, is added to temporal expressions corpus, and according to temporal expressions Corpus establishes the time-critical character library.For example, common temporal expressions text may include the date(On November 3rd, 2012, November 3 etc.), the moment(9: 15 grade), word for expressing date or moment(Tomorrow, morning are first-class)Equal texts.It can manage Solution, the embodiment of the present invention are established mode and are not limited to the specific of specific temporal expressions text and time key word library.
Step S112, matching inquiry is carried out in geographical key word library, to obtain and words phase in the content of text The geographical keyword matched;The geography key word library is to express corpus according to geographical location to establish to obtain;
In practical applications, common geographical location expression text can be collected, geographical location expression corpus is added to, And establish the geographical key word library according to geographical location expression corpus.For example, common geographical location expression text can be with Including:Text for expressing geographical location(Such as Tongfang mansion), for expressing the event that can be mapped to geographical location(One Surely it is happened at the event in specific geographical location)Text(Pharmacy can be mapped to by such as buying medicine event, and oiling event can map To gas station, the event of playing ball can be mapped to arena, and shopping event can be mapped to supermarket or market etc.)Equal texts.It can manage Solution, the embodiment of the present invention express the specific of text time key word library to specific geographical location and establish mode and do not limit.
It should be noted that after executing step S111 and step S112, time-critical word may be only obtained, it is also possible to only Obtain geographical keyword, it is also possible to while obtaining time-critical word and geographical keyword.
Step S113, using with event correlation the time-critical word and/or geographical keyword as with event The trigger condition keyword of relevance.
Remind and complete something in certain time and/or certain geographical location commonly used in prompt user, step S112 obtain when Between keyword can refer to all words with time attribute, still, the word with time attribute might not be with thing Part relevance, the time-critical word without event correlation are worth without prompting.For example, according to language expression Characteristic, for express certain time completion something word will not usually use accurate date or moment(Such as October 3 in 2012 Day, 9 points 30 seconds etc. 15 minutes)It goes to express, be carried in this way, not had usually using the time-critical word that accurate date or moment express It wakes up and is worth, it should abandon.
Similarly, the geographical keyword that step S113 is obtained can refer to all words with geographical location attribute, still, Word with geographical location attribute might not be with event correlation, the geographical keyword without event correlation Without prompting value.For example, according to language express characteristic, for express certain geographical location complete something word lead to The larger geographical location of Chang Buhui use scopes(Such as Beijing, Haidian District, Beijing City etc.)It goes to express, in this way, use scope is larger Geographical location expression geographical keyword usually do not have remind value, it should abandon.
In one preferred embodiment of the invention, described using the time-critical word with event correlation as tactile The step of sending out condition keyword, can specifically include:
Step S1131, the time accuracy of the time-critical word is obtained, and by whether judging the time accuracy Meet preset accuracy condition to judge whether the time-critical word has event correlation;
In the embodiment of the present invention, the time accuracy is used to indicate the accurate journey of time expressed by the time-critical word Degree in the concrete realization can be with the time accuracy of preset certain grade, such as in a kind of application example of the present invention, the time The grade of accuracy has:Roughly, accurate 1 grade, it is 2 grades accurate, 3 grades accurate, corresponding accuracy condition is specifically wrapped It includes:If the time accuracy is accurate 3 grades, the time-critical word does not have event correlation, if the time is accurate Degree is the rank outside accurate 3 grades, then the time-critical word has event correlation.Wherein, the coarse level corresponding time closes Key word, which generally comprises, is accurate to day or day and date incomplete word, such as tomorrow, tomorrow morning, November 3;Accurate 1 Grade generally includes the word for being accurate to hour, such as 9 points of tomorrow morning;The accurate 2 grades words for generally including to be accurate to point, such as 9 Point 15 grades;Accurate 3 grades generally include to be accurate to second or date complete word, such as 9 points 30 seconds 15 minutes, in October, 2012 3 days etc..It is appreciated that those skilled in the art can be according to actual conditions preset time accuracy and corresponding accuracy item Part, the present invention do not limit this.
Step S1132, matching inquiry is carried out in reminder time key word library according to the time-critical word, if matching at Work(, then the time-critical word is with event correlation;The reminder time key word library is to be built according to reminder time corpus Vertical to obtain, the reminder time corpus includes completing the reminder time text of something in certain time for expressing.
Due to completing the reminder time text of something in certain time for expressing(Such as meeting tomorrow morning, 7 points of tomorrow morning It gets up)The characteristic of language expression can be met, and there can be event correlation, therefore, built according to reminder time corpus Reminder time keyword in vertical obtained reminder time key word library has event correlation.
In an embodiment of the present invention, the reminder time key word library can be established as follows:
Step S11321, reminder time text is collected, and is added to reminder time corpus;The reminder time text is used In expression something is completed in certain time;
Step S11322, semantic analysis is carried out to reminder time text in the reminder time corpus, and according to semanteme Analysis result extracts reminder time keyword from the reminder time text;
Step S11323, the reminder time keyword extracted is added to reminder time key word library.
By " meeting tomorrow morning ", " 7 points of tomorrow morning gets up " reminder time text for, then extract to remind and obtain Reminder time keyword is respectively " tomorrow morning ", " 7 points of tomorrow morning ".
It should be noted that in the embodiment of the present invention, reminder time text is used equally for expressing certain with temporal expressions text Time, but one of the main distinction of the two is, and the former completes something for expressing in certain time, and the time of expression also has Event correlation;And the latter is used to express certain time, the time of expression not necessarily has event correlation.
In addition, the present invention is using the time-critical word with event correlation as the scheme of trigger condition keyword, Step S1131 or step S1132 can be individually used, can also use step S1131 and step S1132 to obtain more simultaneously Accurate judging result.
In one preferred embodiment of the invention, described using the geographical keyword with event correlation as tool There is the step of trigger condition keyword of event relevance, can specifically include:
Step S1135, the position fine granularity of the geographical location keyword is obtained, and by judging the position fine granularity Whether preset fine granularity condition is met to judge whether the geographical location keyword has event correlation;
In the embodiment of the present invention, the position fine granularity can be used for indicating geographical location expressed by the geographical keyword Levels of precision.
Those skilled in the art can be set according to actual needs the position fine granularity, for example, for city, institute Rheme sets fine granularity and can specifically include province, city, area, street, community even mansion, commercial circle title etc., the typical case of community Son specifically includes:" five road junctions ", " village Dong Wang ", " village Xi Wang ", " Wangjing " etc., the example of mansion may include " soho network Mansion ", " Tongfang mansion ", " purple light mansion " etc.;For rural area, the position fine granularity can specifically include province, city, County, small towns, village etc.;The application does not limit specific position fine granularity.
In a kind of application example of the present invention, the corresponding fine granularity condition in city can specifically include:If the position Fine granularity is province, city or area, then the geographical location keyword does not have event correlation, if the position fine granularity is street Road, community, mansion or commercial circle title, then the geographical location keyword is with event correlation.Certainly, the present invention is to specific Fine granularity condition does not limit.
Step S1136, carry out matching inquiry in geography reminds key word library according to the geographical keyword, if matching at Work(, then the geographical location keyword is with event correlation;The geographical prompting key word library is to remind language material according to geographical Library is established to obtain, and the geographical prompting corpus includes completing the geographical prompting text of something in certain geographical location for expressing This.
Due to completing the geographical prompting text of something in certain geographical location for expressing(If eyebrow state Dong Po has a dinner party, five road junctions It goes window-shopping Hua Lian)The characteristic of language expression can be met, and there can be event correlation, therefore, language material is reminded according to geographical The geographical geographical prompting keyword reminded in key word library that library is established has event correlation.
In an embodiment of the present invention, the geographical prompting key word library can be established as follows:
Step S11361, geographical prompting text is collected, and is added to geographical prompting corpus;The geographical prompting text is used In expression something is completed in certain geographical location;
Step S11362, text is reminded to carry out semantic analysis to geographical in the geographical prompting corpus, and according to semanteme Analysis result extracts geographical prompting keyword from geographical remind in text;
Step S11363, the geographical prompting keyword extracted is added to geographical prompting key word library.
By " eyebrow state Dong Po has a dinner party ", " five road junction Hua Lians go window-shopping " and it is geographical remind text for, then extract to remind and obtain It is respectively " eyebrow state Dong Po ", " five road junction Hua Lians " that geography, which reminds keyword,.
It should be noted that in the embodiment of the present invention, geography reminds text to be used equally for table with geographical location expression text One of the main distinction up to certain geographical location, but the two is that the former completes something, expression for expressing in certain geographical location Geographical location also have event correlation;And the latter not necessarily has for expressing certain geographical location, the geographical location of expression There is event relevance.
It is appreciated that when judging whether geographical keyword has event correlation, can individually using step S1135 or Step S1136 can also use step S1135 and step S1136 to obtain more accurate judging result simultaneously.
In another preferred embodiment of the invention, the step S110 can also use reminder time key word library and Geography reminds one or both of key word library, triggering item of the extraction with event correlation directly from the content of text Part keyword, correspondingly, the step S110 can specifically include:
Matching inquiry is carried out in reminder time key word library, to obtain the tool to match with words in the content of text There is the time-critical word of event relevance;The reminder time key word library is to establish to obtain according to reminder time corpus, institute It includes completing the reminder time text of something in certain time for expressing to state reminder time corpus;And/or
Matching inquiry is carried out in geography reminds key word library, to obtain the tool to match with words in the content of text There is the geographical location keyword of event relevance;The geographical prompting key word library is to remind corpus to establish according to geographical It arrives, the geographical prompting corpus includes completing the geographical prompting text of something in certain geographical location for expressing.
Step S120, semantic analysis is carried out to the context of the trigger condition keyword, and according to semantic analysis result Event keyword is extracted from the context.
The trigger condition keyword obtained in step S110 has event correlation, and described touch then is to determine in step S120 It is associated with which event to send out condition keyword.
In practical applications, the context of the trigger condition keyword is used to indicate in content of text and the triggering item Part keyword is connected above and below.
