It was found by the inventors of the present invention that for belonging to two INQUIRE statements of different field, although answering this two inquiries
Inquiry message needed for sentence can have very big difference, but different inquiry messages may be identical in information type.
For example, for the INQUIRE statement that belongs to weather field, " how is Pekinese's weather tomorrow" and belong to the inquiry in constellation field
" how is the luck tendency in this week of Taurus for sentence", date-time, and the inquiry that need to be extracted are directed in two INQUIRE statements
Also the extraction of date-time information is directed in information.
Therefore, the present inventor is it is considered that can collect the INQUIRE statement in each field and answer INQUIRE statement institute
The inquiry message needed, and therefrom definition by induction goes out some basic information types, for example, can be taken based on the specific of inquiry message
Value definition by induction goes out：Date-time type, place name type, numeric type, enumerated, eigenmode, community information type, whether the info class such as type
Type；And it for each information type, sets and the corresponding information extraction mode of the information type.In this way, it is determining to answer
After the information type of each inquiry message needed for INQUIRE statement, for each information type, can directly it transfer and the info class
The corresponding information extraction mode of type, extracts the inquiry message for belonging to the information type from INQUIRE statement.It is in this way, right
In belonging to two INQUIRE statements of different field, if answering in each inquiry message needed for the two INQUIRE statements, there are part phases
Same information type, then for identical each information type, may be employed identical information extraction mode to carry out the information
The extraction of the inquiry message of type；Similarly, for each INQUIRE statement, if answering each inquiry message needed for the INQUIRE statement
It is middle to there are the different inquiry messages for belonging to same information type, it can also be extracted using identical information extraction mode and belong to this
The value of the different inquiry messages of information type.
Further, be also contemplated that can be according to the information type of definition, for question answering system branch by the present inventor
The each field held is determined to answer the inquiry message and its info class that belongs to the INQUIRE statement in the field and must include
Type；And for each field, can pre-set with the corresponding field parameter configuration in the field, match somebody with somebody in the field parameter of setting
Answer is stored in putting and belongs to inquiry message and its information type that the INQUIRE statement in the field must include.In this way, per more
It supports a kind of question and answer query service request in field, need to only be directed to the setting that the field carries out field parameter configuration, without
For the newly-increased field increase newly the exploitation of the corresponding question and answer processing unit in field with this again, substantially reduce exploitation week
Phase improves the field scalability of question answering system.
The technical solution that the invention will now be described in detail with reference to the accompanying drawings.
In the embodiment of the present invention, before question and answer processing is carried out to INQUIRE statement, several information types need to be pre-defined,
And it for each information type, sets and the corresponding information extraction mode of the information type.
Specifically, can collect in advance setting quantity belong to the INQUIRE statement of different field after, for each inquiry language
Sentence, determines to answer the inquiry message needed for the INQUIRE statement；And according to the specific value of all inquiry messages determined, base
In XML（EXtensible Markup Language, extensible markup language）Specification or other syntax rules, definition by induction
Go out：Date-time type, place name type, numeric type, enumerated, eigenmode, community information type etc. set the information type of number of species.
It for example, can be by the peculiar word in field（The major styles of cooking of such as food and drink circle, each team name of basketball professional tournament）As row
The inquiry message of act type；It can will meet the information of some features（Such as license plate number, telephone number）Inquiry as eigenmode is believed
Breath；It can will be related to the community information of user as inquiry message of community information type etc..Then, go out for definition by induction
Each information type is set and the corresponding information extraction mode of the information type.Wherein, with the corresponding letter of the information type
Breath extraction mode is specifically what is be configured by those skilled in the art according to common information extraction technique means, for from inquiry
Ask the inquiry message for extracting that computer is intelligible, belongs to the information type in sentence.In fact, the value tool of inquiry message
Body can be the inquiry message of the character string forms extracted from INQUIRE statement；With the corresponding information extraction side of information type
Formula can specifically show as computer program code.
For example, in INQUIRE statement use natural language expressing word, such as " today ", " tomorrow ", " this week ",
" 2014-01-01 ", " 01.01.2014 " etc. meet the word of the form of date-time type, can use and date-time type
Corresponding information extraction mode carries out the extraction of the inquiry message of date-time type from INQUIRE statement and is converted into computer
The intelligible date.For example, may be employed with the corresponding information extraction mode of date-time type, from INQUIRE statement " today north
How is the weather in capital" extract " today ", and " today " for extracting is converted into specific " 2014 01 date on the same day
Month 01 day " afterwards as the date-time type in the INQUIRE statement inquiry message value.
In practical application, place name can generally be divided into five ranks：Country, province, districts and cities, area, street.Therefore, it is right
In the word of place name involved in INQUIRE statement, then may be employed with the corresponding information extraction mode of place name type from INQUIRE statement
It carries out the extraction of the inquiry message of place name type and is converted into the intelligible form of computer.For example, the inquiry of the place name type extracted
Ask that information can be embodied in the Pyatyi form in " country, province, districts and cities, area, street ", for example, " China, Shandong, Qingdao,
Shinan District, Zhuhai are all the way "；Certainly, on the premise of there is not place name ambiguity, the inquiry message of the place name type extracted can also
It shows as the level Four form in " province, districts and cities, area, street " or includes the form of less rank.
For the word of numeric type involved in INQUIRE statement, then may be employed and the corresponding information extraction mode of numeric type
The extraction of the inquiry message of numeric type is carried out from INQUIRE statement and is converted into the intelligible form of computer.For example, it can incite somebody to action
Computer intelligible digital " 360 " is directly extracted as the value of the inquiry message of numeric type, can also be by the number of literal expression
Value type word " 806 " be converted into digital " 860 " afterwards as numeric type inquiry message value.
In practical application, INQUIRE statement may be related to distinctive random enumerated word in the field belonging to it
Language, for example, the major styles of cooking of food and drink circle or each team of team name of basketball professional tournament etc..Therefore, for being related to enumerated word
INQUIRE statement, then may be employed with the corresponding information extraction mode of enumerated, with reference to pre-set neck in question answering system
The lists of keywords in domain extracts the content identical with the keyword in the lists of keywords from INQUIRE statement, and can be straight
Connect the value of the content that will extract as the inquiry message of enumerated.In fact, for distinctive random in field
Enumerated word, may be there are alias, therefore, can also be by the enumerated word for the enumerated word with alias
Alias be arranged in the lists of keywords in the field.
Further, before question and answer processing is carried out to INQUIRE statement, each neck supported for question answering system is also needed
Domain based on information type defined above, is pre-set and the corresponding field parameter configuration in the field, idiographic flow such as Fig. 1
It is shown, include the following steps：
S101：The INQUIRE statement for belonging to the field of predetermined quantity is collected, and for each INQUIRE statement collected, is determined
Go out to answer the inquiry message needed for the INQUIRE statement.
Wherein, each field supported for question answering system belongs to the INQUIRE statement in the field and answers what is collected
Inquiry message needed for INQUIRE statement is collected by those skilled in the art；And the particular content for the INQUIRE statement collected,
And the quantity for the INQUIRE statement collected is rule of thumb to be chosen and adjusted setting, purpose by those skilled in the art
It is to ensure subsequently determine to answer the inquiry that belongs to the INQUIRE statement in the field and must include according to the content of collection
Ask the information type of information.
S102：For each inquiry message determined, the information type of the inquiry message, and the letter that will be determined are determined
Cease information type of the type involved by as the INQUIRE statement.
It specifically, can be according to needed for answering the INQUIRE statement for each INQUIRE statement for belonging to the field of collection
Inquiry message specific value, determine the information type of the inquiry message, and using the information type determined as the inquiry
Ask the information type involved by sentence.Wherein, the information type of inquiry message is based on the specific of the inquiry message counted in advance
Defined in content, it can include：Date-time type, place name type, numeric type, enumerated, eigenmode, community information type etc..
For example, for each inquiry message determined, if exist in the lists of keywords in the pre-set field with
The identical keyword of the value of the inquiry message, the then information type that can determine the inquiry message are enumerated.If the inquiry
The value of information is identical with the place name recorded in place name type corresponding ground list of file names, i.e. the specific value of the inquiry message is related to
The information of place names such as national city are arrived, then the information type that can determine the inquiry message is place name type.If the inquiry message
Value is identical with the community information recorded in the corresponding community list of information of community information type, then can determine the inquiry
The information type of information is community information type.If the ASCII of the inquiry message（American Standard Code for
Information Interchange, ASCII）Code, then can be true in the range of digital ASCII character
The information type of the fixed inquiry message is numeric type.If the value of the inquiry message and the corresponding date-time of date-time type
The keyword recorded in list is identical, then the information type that can determine the inquiry message is date-time type.Further, exist
Determine the information type of inquiry message for after numeric type, can also determine whether the value of the inquiry message of the numeric type is
The no form for meeting date-time type, if so, the information type that can determine the inquiry message is date-time type；Similarly,
It can determine whether the value of the inquiry message of the numeric type meets the regular expression of setting, if so, can be true
The information type of the fixed inquiry message is eigenmode.
S103：The information type that all INQUIRE statements for belonging to the field of collection are related to jointly is determined as and the field
Information type included in corresponding field parameter configuration.
Specifically, for each INQUIRE statement for belonging to the field of collection, by the info class involved by the INQUIRE statement
Type therefrom determines the information type being related to jointly compared with the information type involved by other INQUIRE statements.It is actual to answer
In, since the information type that all INQUIRE statements for belonging to the field are related to jointly can reflect answer to a certain extent
The information type for the key message that the INQUIRE statement in the field must include；In the inquiry message extracted from INQUIRE statement
When containing all key messages, question answering system can find out the answer content of the INQUIRE statement according to inquiry message.Therefore,
It can be using the information type that all INQUIRE statements for belonging to the field of collection are related to jointly as the inquiry language for answering the field
The information type of inquiry message that sentence must include, and be determined as with included in the corresponding field parameter configuration in the field
Information type（It can be also simply referred to as the information type involved by the field herein）.
More preferably, it can also determine after answering the inquiry message needed for each INQUIRE statement, count in step S101
Answer the common inquiry message included needed for all INQUIRE statements collected；Then, for each inquiry message counted,
Determine the information type of the inquiry message.In this way, it is possible to further which the information type of the inquiry message counted is determined
For with the corresponding field parameter configuration in the field included in information type；The institute that the answer counted can also be collected
Have the common inquiry message included needed for INQUIRE statement, be determined as with included in the corresponding field parameter configuration in the field
Inquiry message.
In practical application, for belonging to the INQUIRE statement in different fields, comprising inquiry message may belong to identical
Information type, but the requirement for the specific value of inquiry message has differences.So it more preferably, is setting and the field phase
During corresponding field parameter configuration, the information type involved by the field can also be defined, be increased with this
The discrimination of every field in question answering system, and so that the value positioning of the inquiry message of the information type extracted is more smart
Really, the search efficiency of question answering system is improved.It for example, can be to using what is extracted with the corresponding information extraction mode of numeric type
The value range of inquiry message is defined or to being believed using the inquiry extracted with the corresponding information extraction mode of place name type
The rank of breath is defined.
Field parameter configuration and domain knowledge number based on above-mentioned pre-defined information type and for the setting of each field
According to storehouse, an embodiment of the present invention provides a kind of question and answer processing methods of question answering system, and idiographic flow is as shown in Fig. 2, including as follows
Step：
S201：Question answering system determines the field belonging to the INQUIRE statement after the INQUIRE statement of user's transmission is received.
