{"doi":"10.3145/epi.2021.ene.21","title":"A proposal to revise the disruption index","abstract":"<jats:p>The disruption index (DI) based on bibliographic coupling and uncoupling between a document and its references was first proposed by Funk &amp; Owen-Smith (2017) for citation relations among patents and then adapted for scholarly papers by Wu et al. (2019). However, Wu &amp; Wu (2019) argued that this indicator would be inconsistent. We propose revised disruption indices (DI* and DI#) which make the indicator theoretically more robust and consistent. Along similar lines, Chen et al. (2020) developed the indicator into two dimensions: disruption and consolidation. We elaborate the improvements in simulations and empirically. The relations between disruption, consolidation, and bibliographic coupling are further specified. Bibliographic coupling of a focal paper with its cited references generates historical continuity. A two-dimensional framework is used to conceptualize dis-continuity not as a residual, but a dimension which can further be specified.</jats:p>","journal":"El profesional de la información","year":2021,"id":7526,"datarank":0.40620753016533157,"base_score":2.70805020110221,"endowment":2.70805020110221,"self_citation_contribution":0.40620753016533157,"citation_network_contribution":0.0,"self_endowment_contribution":0.40620753016533157,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":14,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.0487,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2021-02-24","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":4556,"name":"Alexander Tekles","orcid":"0000-0001-8765-9331","position":1,"is_corresponding":false},{"id":661,"name":"Lutz Bornmann","orcid":"0000-0003-0810-7091","position":2,"is_corresponding":false},{"id":663,"name":"Loet Leydesdorff","orcid":"0000-0002-7835-3098","position":0,"is_corresponding":true}],"reference_count":16,"raw_metadata":null,"created_at":"2026-03-01T18:20:47.508186Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
