Office Action

§103
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . This Office Action is in response to correspondence filed 29 April 2026 in reference to application 18/755,364. Claims 1-22 are pending and have been examined. Response to Amendment The amendment filed 29 April 2026 has been accepted and considered in this office action. Claims 1, 7, 10, 14, and 21 have been amended. Claim Objections Claim 21 objected to because of the following informalities: In the amendment, “tagged training” should be “tagged training data”. Appropriate correction is required. Response to Arguments Applicant’s arguments, see Remarks, filed 29 April 2027, with respect to the rejections under 35 USC 101 have been fully considered and are persuasive. The 35 USC 101 rejection of the claims has been withdrawn. Applicant's arguments filed 29 April 2026 with respect to rejections made under 35 USC 103 have been fully considered but they are not persuasive. Applicant argues, see Remarks pages 10-11 that Offer fails to teach the limitation of “indexing the document, indexing the document comprising adding the root words determined for the first plurality of tokens to an index.” The examiner respectfully disagrees. At 0047-51 of Offer teaches that the key terms in the documents are broken into lemma and affixes in order to identify different versions of the same key term. These key terms are then subjected to TF/IDF analysis to determine the important terms and the documents are then annotates with these terms and indexed. Thus the terms, which would include the lemma or root are added to the index along with the document, and thus meet the limitation of the claim. Therefore Offer teaches these limitations. Claim Rejections - 35 USC § 103 The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. Claim(s) 21 and 22 is/are rejected under 35 U.S.C. 103 as being unpatentable over Offer et al. (US PAP 2019/0147109) in view of Nguyen et al. (A Robust Transformation- Based Learning Approach Using Ripple Down Rules for Part-of-Speech Tagging). Consider claim 21, Offer teaches a computer-implemented method comprising: receiving a first plurality of tokens generated from a document to be indexed (0044, tokenization of document text); executing computer code to assign first part-of-speech tags to the first plurality of tokens (0046, part of speech tagging); performing a lemmatization of the first plurality of tokens using the first part-of-speech tags to determine root words for the first plurality of tokens (0047, identifying lemma of each word based on POS tagging); and indexing the document, indexing the document comprising adding the root words determined for the first plurality of tokens to an index (0049-51, generating index based on morphological (lemma) analysis.). Offer does not specifically teach executing optimized computer code to assign first part-of-speech tags to the first plurality of tokens, the optimized computer code embodying ripple down rules generated by a machine learning ripple down rules generator that is trained on tagged training to generate single classification ripple down rules. In the same field of part of speech tagging, Nguyen teaches executing optimized computer code to assign first part-of-speech tags to the first plurality of tokens, the optimized computer code embodying ripple down rules generated by a machine learning ripple down rules generator that is trained on tagged training to generate single classification ripple down rules (section 3, specifically section 3.1, ripple down rules for POS tagging is learned via machine learning, Section 3.2, rules are executed (which requires computer code) to POS tag incoming text, section 3, gold standard training corpus). It would have been obvious to one of ordinary skill in the art at the time of effective filing to use machine learned ripple down rules as taught by Nguyen in the system of Offer in order to generate accurate POS tags automatically with minimal training time (Nguyen Abstract). Consider claim 22, Offer and Nguyen teach The computer-implemented method of claim 21, further comprising: receiving a second plurality of tokens, the second plurality of tokens generated from a search query (Offer 0054, receiving query, applying NPL processing used on documents including 0044, tokenization of document text); executing the optimized computer code to assign second part-of-speech tags to the second plurality of tokens (Offer 0054, receiving query, applying NPL processing used on documents including 0046, part of speech tagging,); performing a lemmatization of the second plurality of tokens using the second part-of-speech tags to determine root words for the second plurality of tokens (Offer 0054, receiving query, applying NPL processing used on documents including 0047, identifying lemma of each word based on POS tagging); and searching the index using the root words determined for the second plurality of tokens (0054-57, searching the index for concepts determining from processing including lemmas). Allowable Subject Matter Claims 1-20 are allowed. The following is an examiner’s statement of reasons for allowance: Consider claim 1, the closest prior art of record, Nguyen et al, teaches A computer-implemented method for a machine learning based rules compiler (abstract), the method comprising: processing a corpus of documents using a machine learning rules generator to generate ripple down rules for part-of-speech tagging for a language, the ripple down rules comprising exception rules for tags in a tag set, the exception rules comprising tag string comparisons (section 3.1, using a corpus of documents to learn ripple down rules for POS tagging. Section 1 provides for exception rules and string comparisons). However the prior art does not specifically teach or fairly suggest the limitations of “compiling the ripple down rules into optimized computer code, further comprising: generating an enumeration statement for an enumeration containing the tag set; translating the exception rules for each tag in the tag set into if-else statements for the tag, translating the exception rules further comprising replacing the tag string comparisons with the enumeration; and generating a switch case statement for a current tag, the switch case statement having a plurality of cases, each case in the plurality of cases corresponding to a respective tag from the tag set and including the if-else statements for the respective tag, wherein the optimized computer code comprises the enumeration statement and the switch case statement.” Rather, the prior art implements ripple down rules in a programing language such as JAVA, so there is no need to further compile them into computer code. Therefore claim 1 contains allowable subject matter. Claims 7 and 14 contain allowable subject matter as claim 1 and therefore contains allowable subject matter as well. Claims 2-6, 8-13, and 15-20 depend on and further limit claims 1, 7, and 14 and therefore contain allowable subject matter as well. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
