Specific embodiment
Below in conjunction with the accompanying drawings the present invention is described in detail with embodiment.
As shown in figure 1, the definite value item matching process of embodiment of the present invention, it comprises the steps：
Step S11, generates each self-corresponding characteristic vector of definite value item to be matched.I.e. each definite value item correspondence can generate a feature
Generally speaking vector, definite value item matching refers to the matching between two definite value items.
Step S12, using the cosine law included angle cosine value between characteristic vector is calculated.Calculate two using the cosine law
Included angle cosine value between each self-corresponding characteristic vector of individual definite value item.
Whether step S13, judge included angle cosine value in the range of pre-set limit.The pre-set limit defines error permission
Scope, only when the included angle cosine value is in the error range of considered critical, can just be judged as that the match is successful.
Specifically, in step s 13, if more than the angle between the characteristic vector corresponding to two definite value items to be matched
String value is judged as that the match is successful in the range of pre-set limit, then；No person, then be judged as that it fails to match.
For example, its concrete matching process substantially can be following manner：
By equipment one（Such as protect letter system and Production MIS）Definite value item 1, the definite value item 2 ... that middle nomenclature is included is calmly
Value item n successively in the way of traveling through respectively with equipment two（Such as fixed value adjusting system）Definite value item 1 ' that middle nomenclature is included,
Definite value item 2 ' ... definite value item n ' is matched.Specifically, by the characteristic vector 1 generated by definite value item 1 successively with by definite value item
1 ' the characteristic vector 1 ' for generating is matched, if matching is unsuccessful, is being carried out with the characteristic vector 2 ' generated by definite value item 2 '
Matching ... is until the match is successful or all matching is completed；Then above-mentioned steps are repeated to definite value item 2.Certainly, equipment one
It is middle to need the definite value item of matching to be set on demand in advance, it is not necessarily required to whole matchings.
Among the step of generation definite value item to be matched each self-corresponding characteristic vector, i.e., in step s 11, including：Will
Definite value item to be matched is analyzed according to preassigned pattern and then generates corresponding characteristic vector.Specifically, the step S11 bag
Include following sub-step：
Step S111, term extraction.
Specifically, according to the title of term table scan definite value item, match the term that includes and be converted to the first predefined value.
Step S112, ordinal number is extracted.
Specifically, term is deleted from title, title is divided into into multiple first segmentations according to delete position, each the
The ordinal number phrase comprising ordinal number is extracted in one segmentation and the second predefined value is converted to.
Step S113, digital extraction.
Specifically, ordinal number phrase is deleted from the comprising ordinal number first segmentation, is again split into according to delete position multiple
Second segmentation, digital value is extracted using as determiner in each second segmentation.
And step S114, it is vectorial according to characteristic value construction feature is extracted.
Specifically, according to the first predefined value, the second predefined value and determiner structural feature vector.
In one embodiment, specifically before the step of generating definite value item to be matched each self-corresponding characteristic vector, i.e.,
Before step S11, also including step S10：The project name of definite value item is collected, nomenclature is built accordingly.
Wherein, the step of nomenclature is built among S10, including：Number to the list item of each nomenclature, and give weight
Value.The parameter of characteristic vector can be optimized by way of numbering and giving weighted value, that what is improved definite value item the match is successful is accurate
Property.

Included angle cosine value.
And judging unit 13, whether judging unit 13 is connected with computing unit 12, for judging included angle cosine value pre-
In the range of value of limiting, if in the range of pre-set limit, being judged as that the match is successful.
The signal generating unit 11 is used to that definite value item to be matched to be analyzed according to preassigned pattern and then be generated corresponding
Characteristic vector.
Further, signal generating unit 11 matches the term for including specifically for the title according to term table scan definite value item
And be converted to the first predefined value；Term is deleted from title, title is divided into into multiple first segmentations according to delete position；
The ordinal number phrase comprising ordinal number is extracted in each first segmentation and be converted to the second predefined value；By ordinal number phrase from comprising ordinal number
First segmentation in delete, according to delete position be again split into it is multiple second segmentation；Digital value is extracted in each second segmentation
Using as determiner；According to the first predefined value, the second predefined value and determiner structural feature vector.
Definite value item matching system also includes the structural unit 10 being connected with signal generating unit 11, and structural unit 10 is used to collect fixed
The project name of value item, builds accordingly nomenclature.Wherein, the structural unit 10 is additionally operable to be numbered to the list item of each nomenclature,
And give weighted value.
