For example, present education resource is audio frequency and video educational resource, and all important word of present education resource has:
" Newton interpolation algorithm ", " acceleration ", " counteracting force "；The current knowledge point of present education resource is that newton second moves
Law, in the first corresponding relation, word corresponding to this knowledge point of Newton interpolation algorithm is that " it is fixed that newton second moves
Rule ", " acceleration "；Determine that the important word that current knowledge point is corresponding is " Newton interpolation algorithm ", " acceleration "；" cattle
Pause second law of motion " occur in that in the resource document of present education resource 3 times, " acceleration " occurs in that in resource document
2 times, the occurred position of " Newton interpolation algorithm " is: 1 point 10 seconds, 2 points 20 seconds, 3 points 30 seconds；Owning of " acceleration "
Occur position be: 1 point 20 seconds, 4 points 10 seconds；1 point 10 seconds is the occurred position of all important word that current knowledge point is corresponding
Put the appearance position of middle foremost, using 1 point 10 seconds as original position, 4 points 10 seconds is corresponding all important of current knowledge point
Rearmost in the occurred position of word there is position, using 4 points 10 seconds as final position, determine current knowledge point pair
The resource segment answered is within 10 seconds, to start to 4 points of fragments terminated for 10 seconds from 1 point in present education resource.
Other knowledge point, therefore, different knowledge points may be also related in the resource segment that certain knowledge point is corresponding
The situation of the possible memory overlay of corresponding resource segment.For example, in the religion corresponding to above-mentioned Newton interpolation algorithm
Educating in resource, also include the knowledge point of gravity, gravity, terminates to the 6th point from the beginning of 10 seconds from the 3rd of this educational resource the point for 30 seconds,
So, the 3rd point of this educational resource starts for 10 seconds, and the fragment to the 6th point of end in 30 seconds is the money that this knowledge point of gravity is corresponding
Source fragment.It is to say, there is coincidence part in resource segment corresponding to the Newton interpolation algorithm resource segment corresponding with gravity
Point, this intersection from the beginning of 10 seconds from the 3rd of educational resource the point, terminates to the 4th point, in intersection, i.e. relates to cattle for 10 seconds
This knowledge point of second law of motion is directed to this knowledge point of gravity.
In order to preferably utilize educational resource, in an embodiment of the present invention, also include: pre-set access times with difficult
Second corresponding relation of degree grade, pre-sets counting principle, and described counting principle includes: at any first use present education
When the resource content of resource comprises more than the preset ratio of Current resource fragment, determine use Current resource fragment once；
After the resource segment that the described each knowledge point determining present education resource is corresponding, also include:
According to described counting principle, statistics uses the access times of Current resource fragment；
Access times according to Current resource fragment and described second corresponding relation, determine the difficulty that Current resource fragment is corresponding
Degree grade.
In general, during user learning, when running into the difficult knowledge point of comparison, this knowledge point can be used for multiple times corresponding
Resource segment, in the present embodiment, by the second corresponding relation by the grade of difficulty of the resource segment of educational resource by making
Reflect with number of times.Assume that preset ratio is 1/2nd, corresponding with this knowledge point of above-mentioned Newton interpolation algorithm
As a example by resource segment, when 2 points of the content of certain broadcasting once educational resource from this resource segment place are from the beginning of 10 seconds, to 5
Point within 40 seconds, terminate, then in this content play from 2 points 10 seconds to 4 points within 10 seconds, be this knowledge point pair of Newton interpolation algorithm
Content in the resource segment answered, this section of content accounts for more than 1/2nd of whole resource segment, so determining that this broadcasting makes
With resource segment corresponding to Newton interpolation algorithm once；When the religion from this resource segment place of the content of certain broadcasting once
Educate 3 points of resource to start for 10 seconds, within 40 seconds, terminate to 6 points, then in this content play from 3 points 10 seconds to 4 points within 10 seconds, be newton
Content in the resource segment that this knowledge point of second law of motion is corresponding, this section of content accounts for 1/2nd of whole resource segment
Hereinafter, so determining that this broadcasting does not use the resource segment that Newton interpolation algorithm is corresponding.Based on this counting principle, system
Count out the access times of each resource segment.
For the second corresponding relation citing, it is as follows that the second corresponding relation is set: when access times are more than or equal to 2000 times, right
Answer difficulty level；When access times are less than 2000 times more than or equal to 1000 times, the more difficult grade of correspondence；Access times are more than or equal to
When being less than 1000 times 500 times, corresponding normal level；When access times are less than 500 times, corresponding easily grade.Such as: as newton
When the access times of the resource segment that this knowledge point of two law of motions is corresponding are 1500 times, then this resource segment can be divided
For more difficult grade, namely knowledge point corresponding for this resource segment is divided into more difficult grade.Teacher can be according to this use
The statistical information of number of times, explains knowledge point for student targetedly, such as: Newton interpolation algorithm is more difficult grade, religion
Teacher can be the most deep explain this knowledge point for student.
As in figure 2 it is shown, embodiments provide a kind of method processing educational resource, the method can include following
Step:
Step 201: pre-set the first corresponding relation of knowledge point and word, pre-set access times and grade of difficulty
The second corresponding relation, pre-set corpus, described corpus includes multiple document, pre-sets counting principle, counts former
Then include: more than the preset ratio comprising Current resource fragment in the resource content of any first use present education resource
Time, determine use Current resource fragment once.
In the first corresponding relation, knowledge point can be by being manually configured, and word corresponding to knowledge point can also
Rule of thumb arranging, word corresponding to knowledge point can be the key word that can embody this knowledge point, such as: newton second transports
The word moving this knowledge point of law corresponding can be " Newton interpolation algorithm ".
It addition, word corresponding to knowledge point can also be come really by the method determining important word in the embodiment of the present invention
Fixed, specifically, obtain current knowledge point corresponding multiple knowledge points document；Each knowledge point document is carried out participle, obtains each
The word that knowledge point document is corresponding；The significance level of each word in the document of each knowledge point is determined according to formula one；Will be every
In the document of individual knowledge point, significance level is at the word of front n name as important word, determines the primary word of each knowledge point document
Language；The word that current knowledge point is corresponding determined in important word according to each knowledge point document, and n here is one to be preset
Value.Specifically, can be using important word the highest for significance level in the important word of each knowledge point document as current knowledge
The word that point is corresponding, or, using the highest for the frequency of occurrences in all important word in the document of all knowledge points as currently knowing
Know the word that point is corresponding.
Step 202: identify present education resource, determine the resource document that present education resource is corresponding.
Here present education resource includes: audio frequency and video educational resource, document educational resource, specifically, can be audio frequency
Form, visual form, word form, pdf form, ppt form etc..When for various types of educational resources, all by therein
Content Transformation is resource document.Such as: for audio frequency and video educational resource, the identification of audio frequency and video can be carried out, generate resource document；
For the educational resource of word, pdf or ppt form, Text region can be carried out, extract word content therein, generate money
Source document.
Generate resource document time, can in resource document coal addition position, for example, at audio frequency and video educational resource
In, " cattle " this word identifies at 10 points for 10 seconds, then the position of " cattle " this word be 10 points 10 seconds；In word form, pdf shape
In the educational resource of formula or ppt form, " power " this word identifies at page 2 the 3rd row, then the position of " power " this word
For page 2 the 3rd row.
Step 203: resource document carries out participle, obtains the word that resource document is corresponding.
After obtaining the word that resource document is corresponding, it can be each word mark position.Specifically, can be by each word
The position of language first character is as the position of this word, or using the position of each word the last character as the position of this word
Put.For example, in resource document, the position of " cattle " in " Newton interpolation algorithm " be 10 points 10 seconds, the position of " rule "
Put be 10 points 12 seconds, then can be using 10 seconds positions as " Newton interpolation algorithm ", 10 points, position of " cattle ", it is also possible to will
12 seconds positions as " Newton interpolation algorithm ", 10 points, the position " restrained ".
Step 204: determine each word occurrence number in resource document, determines the quantity of document in corpus, point
Do not determine the quantity of the document comprising each word in corpus.
When performing the quantity determining the document comprising each word in corpus respectively, for each word, determine
The quantity of the document of this word is comprised, for example, the word that resource document is corresponding includes: " newton " " weight in corpus
Power ", it is determined that in corpus, comprise the quantity of the document of " newton ", and determine the document comprising " gravity " in corpus
Quantity.
Step 205: determine the significance level of each word according to formula one.
Wherein, described formula one includes:
Wherein, F is the significance level of arbitrary word, and n is this word occurrence number in resource document, and N is resource literary composition
The occurrence number sum of all words in Dang, M is the quantity of document in corpus, and m is the literary composition comprising this word in corpus
The quantity of shelves.
Step 206: using significance level in resource document at the word of front preset value name as important word.
For example, preset value can be 10, then using significance level at the word of top 10 as important word.
Step 207: according to the first corresponding relation, determine the knowledge point that each important word is corresponding.
Above-mentioned preset value could be arranged to bigger value, and such as 100,1000 etc..Because knowledge point also needs to and first
Corresponding relation carries out coupling and just can determine that, and word corresponding to each knowledge point will not be typically everyday words.For example, in time
Important word includes: " " everyday words such as "Yes", the word that each knowledge point of the first corresponding relation is corresponding the most also will not
Including " " everyday words such as "Yes".
In the present embodiment, it is determined by important word and carrying out with the first corresponding relation to mate two steps and determine and know
Know point, so that the knowledge point determined is more accurate.
Step 208: using knowledge point corresponding for each important word as the knowledge point of present education resource.
Because the important word that the present embodiment is determined can reflect the content of educational resource more accurately, all, logical
Cross knowledge point that important word determines also the most accurately.
Step 209: the important word corresponding according to present education resource and the first corresponding relation, determines present education resource
Important word corresponding to each knowledge point.
In this step, important word corresponding to each knowledge point may have multiple, and may have in these important words
Identical word, but position is different.For example, the current knowledge point of present education resource is Newton interpolation algorithm,
Determine that important word corresponding to this knowledge point is for " Newton interpolation algorithm "；" Newton interpolation algorithm " is at present education
Occurring in that in the resource document of resource 3 times, the occurred position of " Newton interpolation algorithm " is: 1 point 10 seconds, 2 points 20 seconds,
3 points 30 seconds, although be same word, but position be different.In this step, corresponding each heavy of current knowledge point is determined
Want all positions of word.
Step 210: respectively by the going out of foremost in the occurred position of all important word corresponding for each knowledge point
Existing position is as original position.
Described above " Newton interpolation algorithm ", the appearance position of foremost be 1 point 10 seconds, then original position is 1 point
10 seconds.
It is of course also possible to using before the appearance position of foremost, the position of preset increments is as original position, such as: preset
Increment is 10 seconds, then using the position of 10 seconds before the appearance position of foremost as original position；Can also going out foremost
After existing position, the position of preset increments is as original position, such as: preset increments is 10 seconds, then by the appearance position of foremost
The position of 10 seconds is as original position afterwards.User can rule of thumb or need arrange flexibly.
Step 211: respectively by the occurred position of all important word corresponding for each knowledge point rearmost go out
Existing position is as final position.
