Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with examples and drawings to this hair
It is bright to be described in further detail.
As shown in Figure 1, being the individualized knowledge library recombination method process based on domain knowledge, comprising the following steps:
Step 10 chooses interested domain knowledge according to user demand again；
Step 20 carries out necessary screening conditions setting to whether the corresponding material of knowledge is selected into knowledge base；
Step 30 combines corresponding material screening conditions, constructs corresponding story extraction instruction, that is, constitutes restructuring plan；
The knowledge distributing that step 40 is related to according to instruction is extracted, is executed parallel, is generated knowledge base, that is, is performed recombination
Plan；
Step 50, which is added not extracting the interested material into knowledge base or delete to have extracted, does not feel emerging into knowledge base
The material of interest.
Above-mentioned steps 10 are reconstruct domain knowledge；Domain knowledge is usually the professional domain knowledge body of society, commercial press building
System describes usually in the form of field vocabulary or domain body.Domain knowledge includes the pass between concept and concept in field
It is that the relationship in typical field vocabulary includes use, generation, category, divides, ginseng, and domain body also typically includes built-in generality and closes
It is (such as antisense) and a large amount of customized relationship.Domain knowledge usually carries out tissue (such as vocabulary by the taxonomical hierarchy of concept
In category divide relationship, the SubClassof relationship in domain body), it can be understood as the concept system of multiple trees, i.e.,
Constitute the structure of forest.Domain knowledge is constructed generally directed to specific professional domain, the range (or being interpreted as granularity) being related to
It is changeable, depending on specific application demand.In addition, domain knowledge is since its is professional, often while automatic building,
The participation of a large amount of domain expert is needed, artificial editor and audit are carried out.
Under the scene of individualized knowledge library recombination, domain knowledge needs to carry out certain reconstruct, to meet of user
Property demand.In view of the professional and authoritative of domain knowledge, change the tissue of domain knowledge with throwing the reins to it is difficult to ensure that neck
The consistency of domain knowledge does not generate contradiction in logic, therefore, the domain knowledge reconstruct that this patent is related to is pertained only to for existing
There are the merging and screening of domain knowledge.The merging of domain knowledge, which refers to, (may be from different fields in existing domain knowledge
Knowledge hierarchy) concept extract in the demand in current knowledge library；The screening of domain knowledge refers to the domain knowledge concept of selection
The related notion being related to is deleted, and the concept that user is concerned about conscientiously is only chosen.Use can be generated in above domain knowledge reconstruct
Family describes the personalization of concept needed for knowledge base.Typically, since concept may relate to different knowledge hierarchy, and pass through
Screening, can constitute multiple tree-shaped hierarchical structures, i.e. forest.
Reconstruction field knowledge interacts as shown in Fig. 2, listing the available multiple fields knowledge hierarchy of user, and user is by dragging
It drags corresponding concept and chooses the knowledge point that knowledge base is related to, optionally delete the sub- concept of conceptual dependency.
Above-mentioned steps 20 are configuration screening conditions (as shown in Figure 3), under the scene of individualized knowledge library recombination, configuration sieve
The material for selecting condition to refer to that regulation knowledge base includes needs the condition met, is generally screened by the associated metadata of material.
For commercial press field, screening conditions are typically comprised: author, copyright information, publisher, time range,
Languages, user oriented positioning etc..Different applications may relate to different metadata screening conditions, can be dynamic by configuration file
The screening item that state loading system is supported.
Above-mentioned steps 30 are to generate restructuring plan (as shown in Figure 4), and restructuring plan is the inside table of regrouping knowledge base instruction
Show, for describing how automatically to extract the associated material of domain knowledge.Since domain knowledge is usually the number of a forest
According to structure, while knowledge base is configured with screening conditions, therefore corresponding executive plan is usually the data structure of a forest,
In each tree construction represent the domain knowledge concept of user's needs, and be labelled on tree construction the screening conditions of configuration.It should
The screening conditions that the domain knowledge and step 20 that process can be reconstructed easily by step 10 configure are constructed.
Above-mentioned steps 40 are to execute restructuring plan (as shown in Figure 5), and executing recombination strategy is the recombination configured to step 30
Strategy explains execution, generates the process of recombinant product.Typical implementation procedure is that traversal restructuring plan each of is related to knowing
Know item, according to screening conditions, the relevant material of the knowledge item is extracted from material database.The foundation of extraction is usually the index of material
, if material itself lacks index item, text-type material can be extracted by way of full-text search.
The execution of reassembly algorithm is usually directed to the story extraction of different domain knowledge items, therefore can use parallel execution
Method with raising efficiency, such as in the case where single machine in the way of multithreading, or utilize under distributed environment
The thought of Map-Reduce.
Above-mentioned steps 50 are the adjustment (as shown in Figure 6) of content material, and the knowledge base constructed automatically based on above step is very
Difficulty accomplishes to comply fully with the demand of user, therefore is introduced into the mechanism of content material in adjustment knowledge base.The step is man-machine interactively
Adjustment process, user can delete the uninterested material extracted, can also be added and be felt based on the demand of oneself
The material of interest.
Although disclosed herein embodiment it is as above, the content is only to facilitate understanding the present invention and adopting
Embodiment is not intended to limit the invention.Any those skilled in the art to which this invention pertains are not departing from this
Under the premise of the disclosed spirit and scope of invention, any modification and change can be made in the implementing form and in details,
But scope of patent protection of the invention, still should be subject to the scope of the claims as defined in the appended claims.
