General introduction
The intellecture property document adopts static document vector and dynamic document vector.To specifically set off a discussion below to patent documentation.In one embodiment, document vector can be applicable to any intellecture property document.Document vector is (keyword, weight) right set, and wherein keyword is speech or the phrase relevant with base document, and weight is the numerical metric of the importance of this keyword in document.More specifically, document vector is a kind of document identification mark, and it is used for representing literature content with the mode that helps the comparison between the document.It is the numeral that does not receive structurized word content of document.Because the patented claim of patent and announcement can frequently not change, so static document vector is associated with these documents.The dynamic document vector is associated with the polling character string data (hereinafter being called character string) that is submitted to the patent documentation set.Static document vector can resolve to gets rid of the peculiar character string of patent and almost nugatory character string when retrieving.The character string of being got rid of is called " stop-word ".In one embodiment, stop-word used herein is that patent field is distinctive.In addition, the chapters and sections that have regulation in every piece of patent documentation, each chapters and sections are represented the different piece of patent documentation.When carrying out patent retrieval, the different chapters and sections of patent documentation are provided with different values.Like this, according to the scope of patent retrieval, can retrieval be restricted to the particular chapter of patent documentation.So; In the patent documentation set, adopt document vector; So that through coming to generate efficiently and effectively results set with the relevant data of inquiry that are committed to the patent documentation set; This results set is one or more documents in the patent documentation set, and the static document vector of above-mentioned one or more documents is in calculating drops into the setting mathematics scope of the dynamic document vector relevant with the polling character string data of being submitted to.
Ins and outs
In the following description of embodiment, describe with reference to the accompanying drawing that is used to constitute this paper part, these accompanying drawings represent can embodiment of the present invention specific embodiment.Should be appreciated that without departing from the scope of the invention and can carry out structural change, thereby can adopt other embodiment.
Fig. 1 is the overview flow chart (100) of the retrieval of expression electronic literature set, and more specifically, it is the overall retrieval flow figure (100) of the expression patent set relevant with patent publications.At first, to the set of patent documentation collect (step 102).It should be understood that patent and patent publications are to be made up of a plurality of chapters and sections.After these documents of compilation, be this set produce index (step 104), the produce index process of this compilation comprises: data acquisition is converted to be suitable for search and data retrieved storehouse.More specifically, the authorized index of document set comprises: the document vector (step 106) that obtains each patent documentation in the set.Document vector comprises the weight list of speech and phrase.In one embodiment, the term that is selected into document vector includes but not limited to: the frequent speech that occurs in noun phrase, the speech that does not appear at beginning of the sentence and initial caps and the document.Calculating is placed into the weight of the term in the vector.In one embodiment; The following method that is used for calculating weight can include but not limited to: with speech change into numerical value between 1 and 0 (wherein, being assigned to the speech that the most often occurs in the document) in the frequency standard that document occurs, increase the right weight of speech or speech in the selected zone of document 1, to noun phrase specify higher weight, improve the speech of the initial caps in the document text weight, and relatively short character string specify higher weight to longer character string.In case selected to list in speech and phrase in the document vector, and selected weight, calculated document vector through using integrator for these speech and phrase.In one embodiment; Integrator can select two ways to list in the vector and the weight of listed speech and phrase increases degree, can select each factor to the percentage contribution of final term weight and can entity type be added in the incoming vector; For example; Improve the importance of the corporate entity that finds hereof, and increase the stop-word tabulation to remove the common phrase of finding in the database.The document vector that generates for each patent documentation in the set is called " static document vector ".
Except that indivedual exceptions, in case the patent documentation announcement can not change usually.And exception includes but not limited to: the examination once more of the issue of certificate correction, issued patents and the announcement once more of issued patents.In order to handle these exceptions, need to upgrade the document set.More specifically, Time Created at interval, with any variation (step 108) of the document that is used for upgrading set and relevant document vector.The example in the time interval includes but not limited to: every month, every half a year, annual or the like.Then, judge the time interval set up whether expire (step 110).If the judged result that step (110) is located is sure, then next turn back to step (102).Otherwise, as if the judged result that step (110) is located negate, then next wait for the period that sets, to upgrade the patent documentation vector,, next turn back to step (110) so that all changes of patent documentation are joined (step 112) in the document vector.In one embodiment, patent documentation is not limited to granted patent, also comprises the patented claim of announcement.Therefore, in view of the inherent attribute of patent, the patent documentation set should regular update, to handle all changes of all patents in the set.
In case resolved the document set to generate the static document vector of this set, just can inquire about this set.Fig. 2 is the overall process of inquiry is submitted in expression to the patent documentation set a process flow diagram (200).At first, receive input inquiry (step 202).In one embodiment, input inquiry is made up of character string.For input inquiry generates document vector (step 204).Because the document vector of inquiry generates when submitting to, so hereinafter is referred to as " dynamic document vector ".The dynamic document vector is based on that the text input of inquiry generates.More specifically, the dynamic document vector is to be made up of the maximally related term in the inquiry input text.In order to select character string included in the dynamic document vector, and, can adopt different tools for to the selected term allocation weight that is included in the dynamic document vector.In one embodiment, extract following character string from input inquiry: the frequent twin words that occurs in the frequent speech that occurs, the document in the speech of noun phrase, initial caps (that is, first letter capitalization but do not appear at beginning of the sentence), the document.For the stop-word of the appointment in the static document vector, it is removed from dynamic document vector, thereby be not included in the dynamic document vector.After the text from input inquiry has extracted the selected term that is included in the dynamic vector, be these term allocation weights.In one embodiment, the frequency standard that each speech or phrase are occurred in document changes into the numeral between 1 and 0, wherein distributes to the speech that the most often occurs in the document with 1.Equally, in one embodiment, increase weight such as speech in the special areas such as title or twin words; Distribute higher weight to noun phrase; Increase the weight of the speech of the initial caps in the document text, distribute to longer character string to be higher than weight than short character strings, or the like.The calculating of document vector has higher configuration property.In one embodiment, the user can be to retrieval term allocation weight.Therefore, can use following various tool, this instrument can generate the appropriate dynamic document vector based on the inquiry input.
In step (204) afterwards, the inquiry with dynamic document vector form is submitted to document set (step 206), wherein, the static document vector in dynamic document vector and the patent documentation set is compared (step 208).Then, judge in the document set whether have the static document vector (step 210) in the definition mathematics scope that falls into the dynamic document vector.If the judged result of step (210) is sure, all in then next document being gathered have one or more basic patent documents that fall into the static document vector in the definition mathematics scope and put into result set (step 212).In step (212) afterwards or when the judged result located of step (210) was to negate, whether judges hoped to submit new inquiry (step 214) to the document set.In one embodiment, the new inquiry scope that can dwindle the inquiry of previous submission.Similarly, new inquiry also can enlarge the scope of the inquiry of previous submission.No matter the scope of new inquiry how,, then next turn back to step (204) if the judged result that step (214) is located is sure.Similarly, the negative evaluation located of step (214) shows that the inquiry submission process to the document set finishes.Therefore, the submission inquiry to the document set comprises: convert the character string of submitting to the dynamic document vector, and the static vector of dynamic document vector with the document set compared.
The patent documentation set is the set of unique technique document.The form of patent documentation has the granted patent and the disclosed patented claim of bulletin.Difference between these two types of documents has been confirmed their power of enforcement.More specifically, granted patent is to be weighed by the realized property that law court executes, and disclosed patented claim is the application of unexamined, is patent right undetermined.Every piece of patent documentation writing comprises speech and phrase habitual in the application.Yet, because these speech and phrase appear in most of patent documentations, and be not that invention is peculiar, so these speech and phrase almost do not have the value retrieved.For example, the example of these speech and phrase includes but not limited to " embodiment ", " exemplary ", " prior art " or the like.Similarly, can have different everyday words in each national patented claim.For example, in some country, speech " is characterised in that " it is everyday words, does not almost have the value of authorizing or retrieving.Here, these speech are called " stop-word ".The purpose that is used to discern country, language and/or cultural peculiar stop-word is to make the scale of the document vector of treating to retrieve as much as possible little.Can resolve each document vector in the patent documentation set, so that the stop-word of confirming is removed from the document set.
Fig. 3 is that the process flow diagram (300) of stop-word with the process of the static document vector in the further parsing patent documentation set used in expression.Before submitting inquiry to, judge whether to resolve stop-word to obtain static document vector to the document set.Stop-word is subject to particular country (302), language-specific (304) and/or particular culture (306).After positive response, generate the compilation of stop-word, so that resolve the static document vector (step 308) in the patent documentation set to step (302), any single selection that (304) and/or (306) are located or combination selection.To the set of patent documentation collect (step 310).In one embodiment, the set of patent documentation possibly be subject to selected country, language and/or particular culture.At compilation document (step 310) afterwards, be set produce index (step 312), and from set, parse stop-word (step 314).Produce index and the process that from compilation, removes stop-word comprise: data acquisition is converted to be suitable for search and data retrieved storehouse.In step (314) afterwards, one or more chapters and sections of selecting set Chinese to offer are with in the document vector to be generated that adds set (step 316).Based on the selection of at least one chapters and sections in the step (316), for each patent documentation in the set generates document vector (step 318).More specifically, compile in collaboration with the system index for archives after, the document vector that is selected chapters and sections of every piece of patent documentation in obtaining gathering, and the stop-word of deletion warp identification from resulting document vector.Here, this type document vector is called static document vector.
Only if indivedual special circumstances, in case the patent documentation bulletin can not change usually.In order to handle these indivedual special circumstances, upgrade the document set aperiodically.More specifically, Time Created is (320) at interval, so that any variation of document in the pair set and related document vector is upgraded.For example, the time interval includes but not limited to every month, every half a year, annual or the like.The time interval of judge setting up then, whether expire (322).If the judged result located of step (322) negates, then next wait for the time cycle of setting (324), upgrading the patent documentation vector, thereby any variation of patent documentation is joined in the document vector, turn back to step (320) afterwards.Yet,, next judge whether to exist any new stop-word (step 326) in the document set that is applied to if the judged result located of step (322) is sure.If the judged result that step (326) is located negates then next to turn back to step (310); If the judged result located of step (326) is sure, then next new stop-word and/or phrase are joined in the compilation of irrelevant patent term (step 328).In step (328) afterwards, the generation and/or the renewal process of the static document vector of patent documentation set turn back to step (310).Thereby, can resolve static document vector, select stop-word, thereby can the submission of inquiry be focused on the relevant character string in the static document set through identification.
It should be understood that bulletin patent and disclosed patented claim are divided into a plurality of chapters and sections.Submit complete patented claim to, each chapters and sections of patent documentation all are essential, and each chapters and sections of patent all have its purposes.No longer go through the details of each chapters and sections of patented claim at this.Yet, will identify these different chapters and sections.In most cases, each patented claim comprises title, priority date, summary, background technology, summary, brief description of drawings (if any), embodiment and claim.In the patent activity, adopt different retrieval classifications according to the retrieval purpose.For example, it is relevant with the speech in the claim that infringement and/or product are really weighed retrieval, thereby should retrieve the claim that exists in the document set.Effective and/or invalid retrieval is relevant with any known systems, and need examine the priority date of patent documentation.Before the inventor is submitting patented claim to or after when wanting to judge their novelty of an invention, inventor perhaps his/her procurator or representative can adopt novelty search.This retrieval can de-emphasize claim, and pays close attention to the embodiment of invention.Therefore, as described herein, every kind of retrieval focuses on the different chapters and sections of the patent documentation in the document set.
As stated, can resolve each patent in the document set, to be chosen in the fashionable almost nonsensical stop-word of retrieved set.Yet except selecting stop-word, also expectation is single patent documentation a plurality of static document vectors that collect, and each of the patent documentation in each different document vector and the set is relevant through discerning chapters and sections.The generation of a plurality of document vectors (wherein each document vector is used to discern a particular chapter) can make the retrieval of document set become accurate based on the range of search that defines.For example, can the infringement retrieval of document set be limited to the relevant document vector of claim chapters and sections of each patent in the document set.
Fig. 4 is expressed as the process flow diagram (400) that every piece of patent documentation in the set generates the process of a plurality of document vectors.At first, the set (step 402) of compilation patent documentation, and be its produce index (step 404).With variable M
TotalBe appointed as the sum of the document in the patent documentation set, counting variable M is appointed as integer 1 (step 408).Identify the quantity (step 410) of the chapters and sections that the patent documentation M in the set had.In step (410) afterwards, variable N
TotalBe appointed as the sum of the chapters and sections among the patent documentation M, counting variable N is appointed as integer 1 (step 414).Each chapters and sections generation document vector for every piece of patent documentation in the set.More specifically, generate document vector (step 416) for each chapters and sections N among the patent documentation M.In case locate to generate document vector in step (416), if patent documentation also has other chapters and sections, counts variable N (step 418), thus get into the next chapters and sections of patent documentation so that generate next document vector for next chapters and sections.In step (418) afterwards, judge whether also there are other chapters and sections (step 420) that will generate document vector in the patent documentation.If the judged result that step (420) is located negates then next to turn back to step (416).Otherwise,, then next increase progressively variable M (step 422) if the judged result that step (420) is located is sure.Then, judge whether each document in the set has received parsing to generate a plurality of document vectors (step 424).The judged result of locating in step (424) be negate the time, next turn back to step (410), for the next document in the set generates a plurality of document vectors.As stated, known in the art is possibly need the static document set of regular update.The frequency of upgrading possibly be frequent or not frequent, and this depends on the accuracy of set.In one embodiment, the renewal frequency of static document vector can be proportional with the bulletin speed of patent.The affirmative determination result that step (424) is located is indicated as every piece of patent documentation and generates a plurality of document vectors and resolved the patent documentation set.Then, the time interval of judging the static vector be used for upgrading set whether expired (step 426).If the judged result that step (426) is located is sure, then next turn back to step (402).Otherwise, as if the judged result that step (426) is located negate, then next turning back to step (426) before, wait for the time interval of setting, so that upgrade the patent documentation vector, thereby any variation of patent documentation is joined (step 428) in the document vector.Thereby, can resolve every piece of patent documentation in the document set, to generate a plurality of static document vectors, wherein each vector is relevant with warp identification chapters and sections of patent documentation.
In case thereby patent documentation has been resolved to each document in the set generates a plurality of document vectors, the inquiry of submission just can balanced utilize the parsing of document chapters and sections.Fig. 5 is the process of inquiry is submitted in expression to the document set with a plurality of document vectors a process flow diagram (500).At first, submit to the user of inquiry to define the scope (step 502) of retrieval to set.In one embodiment, can the graphic user interface as the panel of computer instruction be provided, thereby be convenient to select the scope retrieved to the user.In step (502) afterwards, the range of search that defines is associated (step 504) with the document vector classification of selecting for the document set, and submits inquiry string (step 506) to the document set.Then, for the inquiry string of being submitted to generates dynamic document vector (step 508), the dynamic document vector is committed to the document set to confirm related document (step 510).The comparison (step 512) between the static document vector of selection that is subject to dynamic document vector and document set is submitted in inquiry to.In one embodiment, the static document vector of selection can be one group of static document vector (step 513) selecting.More specifically, the retrieval that is subject to the claim chapters and sections in the patent documentation is the static document vector of the sharp claim chapters and sections of patent searching document set special secondary school or the group of similar static document vector only.In the step (512) relatively is the mathematics comparison between dynamic document vector and the static document vector.Based on mathematics relatively, with result set relatively sort (step 514).In one embodiment, carry out above-mentioned ordering according to the static document vector of document set and the degree of approach (closeness) of dynamic document vector.Thereby, the static document vector through dynamic document vector and set relatively produced result set.
In case result set is sorted (step 514), the degree of approach scope (step 516) that is confirmed as related document that just adopts numerical value to define to be sorted.In step (516) afterwards, judge in ordered set, whether to exist any document to drop in the mathematics scope that defines (518).If the judged result located of step (518) is sure, the tabulation that then next static document vector is in all basic patent in the confining spectrum of dynamic document vector is placed on (step 520) in the result set.In step (520) afterwards or when the comparative result located of step (518) is to negate, whether judges wants to submit to new inquiry string or the further previous inquiry string of submitting to (step 522) of restriction.If the result of determining step (522) negates to show that then inquiry submission process finishes.Otherwise if the judged result located of step (522) is sure, then next whether judges wants to change the chapters and sections (that is static document vector) (step 524) of comparing with inquiry (that is dynamic document vector) in the retrieval.In one embodiment, can directly change the selection of the static document vector that uses in the retrieval through the scope that changes retrieval.If the judged result that step (524) is located is sure, then next turn back to step (502), new inquiry will change the chapters and sections that in the next round inquiry, will assess in the patent documentation.Otherwise, as if the judged result that step (524) is located negate, show that then new inquiry will further limit the scope of previous inquiry, keep restriction simultaneously to the document vector identical in the patent set with previous inquiry.In this way, after judged result negates, submit the inquiry of further revising to, and do not submit the document vector of patent documentation set to, turn back to step (506) then.Thereby, can revise the scope of retrieval from two aspects, thereby relatively revise results set according to the static document vector of the dynamic document vector of inquiry and patent documentation set.
