Abstract: 【Purpose/significance】To understand the current status of e-service in public libraries, and analysis factors influencing readers’satisfaction of e-services.【Method/process】Online review data of 10 public libraries were crawled, and an e-service diction⁃ ary was constructed. An e-service review corpus were established via matching the dictionary with online reviews. The Senta_BiLSTM model was employed to analysis the e-service review sentiment, and the reviews were categorized based on the sentiment. The factors impacting e-service satisfaction were extracted.【Result/conclusion】Four categories of public library e-service were constructed, and the factors positively or negatively impact satisfaction of e-service in public libraries were identified. The conclusions can shed light on the digitalization construction strategy for public libraries.【Innovation/limitation】This study constructed the public library eservice dictionary, and explored user satisfaction toward e-service. However, public library e-service dictionary construction might be impacted by subjective perceptions of researchers, and only ten public libraries were selected. More cases and data can be included in the future to enrich public library e-service dictionary.
