However, previous works on applying SVMs to the F-term patent classification task did not obtain as good results as other learning algorithms such as kNN. This is due to the fact that F-term patent classification is different from conventional document classification in several aspects, mainly because it is a multiclass, multilabel classification problem with semi-structured documents and multi-faceted hierarchical categories.<\/jats:p>\n          <jats:p>This article describes our SVM-based system and several techniques we developed successfully to adapt SVM for the specific features of the F-term patent classification task. We evaluate the techniques using the NTCIR-6 F-term classification terms assigned to Japanese patents. Moreover, our system participated in the NTCIR-6 patent classification evaluation and obtained the best results according to two of the three metrics used for task performance evaluation. Following the NTCIR-6 participation, we developed two new techniques, which achieved even better scores using all three NTCIR-6 metrics, effectively outperforming all participating systems. This article presents this new work and the experimental results that demonstrate the benefits of the latest approach.<\/jats:p>","DOI":"10.1145\/1362782.1362786","type":"journal-article","created":{"date-parts":[[2008,5,28]],"date-time":"2008-05-28T12:21:21Z","timestamp":1211977281000},"page":"1-19","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Adapting Support Vector Machines for F-term-based Classification of Patents"],"prefix":"10.1145","volume":"7","author":[{"given":"Yaoyong","family":"Li","sequence":"first","affiliation":[{"name":"University of Sheffield, UK"}]},{"given":"Kalina","family":"Bontcheva","sequence":"additional","affiliation":[{"name":"University of Sheffield, UK"}]}],"member":"320","published-online":{"date-parts":[[2008,4]]},"reference":[{"volume-title":"Proceedings of the 11th Text Retrieval Conference (TREC'02)","author":"Cancedda N.","key":"e_1_2_1_1_1"},{"volume-title":"Proceedings of the Conference on Advances in Neural Information Processing Systems (NIPS'04)","author":"Cesa-Bianchi N.","key":"e_1_2_1_2_1"},{"volume-title":"An Introduction to Support Vector Machines and Other Kernel-Based Learning Methods","author":"Cristianini N.","key":"e_1_2_1_3_1","doi-asserted-by":"crossref","DOI":"10.1017\/CBO9780511801389"},{"volume-title":"Proceedings of the 6th NTCIR Workshop Meeting on Evaluation of Information Access Technologies: Information Retrieval, Question Answering and Cross-Lingual Information Access (NTCIR'07)","author":"Fujino A.","key":"e_1_2_1_4_1"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1145\/500933.500944"},{"volume-title":"Proceedings of the 6th NTCIR Workshop Meeting on Evaluation of Information Access Technologies: Information Retrieval, Question Answering and Cross-Lingual Information Access (NTCIR'07)","author":"Hashimoto K.","key":"e_1_2_1_6_1"},{"volume-title":"Proceedings of NTCIR-5 Workshop Meeting.","author":"Iwayama M.","key":"e_1_2_1_7_1"},{"volume-title":"Proceedings of the 6th NTCIR Workshop Meeting on Evaluation of Information Access Technologies: Information Retrieval, Question Answering and Cross-Lingual Information Access (NTCIR'07)","author":"Iwayama M.","key":"e_1_2_1_8_1"},{"key":"e_1_2_1_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/BFb0026683"},{"key":"e_1_2_1_10_1","doi-asserted-by":"publisher","DOI":"10.5555\/1005332.1005345"},{"volume-title":"Proceedings of the 1st International Workshop on Evaluating Information Access (EVIA'07)","author":"Li Y.","key":"e_1_2_1_11_1"},{"volume-title":"Proceedings of the 6th NTCIR Workshop Meeting on Evaluation of Information Access Technologies: Information Retrieval, Question Answering and Cross-Lingual Information Access (NTCIR'07)","author":"Li Y.","key":"e_1_2_1_12_1"},{"volume-title":"Proceedings of The 17th Pacific Asia Conference on Language, Information and Computation (PACLIC17)","author":"Li Y.","key":"e_1_2_1_13_1"},{"key":"e_1_2_1_14_1","doi-asserted-by":"publisher","DOI":"10.2481\/dsj.6.S255"},{"volume-title":"Proceedings of Machine Translation Summit IX.
