To compare the results with other studies, we conducted experiments on two benchmark datasets for the Russian language. The results for named entity recognition demonstrate significant improvement and outperform the state-of-the-art results. Our results for relation extraction are comparable to other research.

Sentence segmentation, a subfield of text segmentation, is the problem of dividing a string of natural language text into its component sentences. Current methods of sentence segmentation are often either hardcoded—they require manual implementation of fixed grammar and segmentation rules—or require extensive training on labeled corpora and are not explainable—they are \"black box\" algorithms that cannot be understood by humans. In this paper, we present a novel explainable sentence segmentation method capable of separating bodies of text into grammatically valid sentences solely based on the grammatical relationships between individual words or tokens. The proposed NLS architecture can both automate the input query parsing and semantic query execution components of voice-activated question answering and information retrieval systems as well as enable automatic summarization, entity extraction, sentiment identification, and a variety of other natural language processing (NLP) algorithms that operate at the sentential level.","PeriodicalId":201402,"journal":{"name":"2020 Science and Artificial Intelligence conference (S.A.I.ence)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125165988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The docking control sites were: Y745 (tyrosine 745), a critical site for TRPM8. We also analyzed the intermolecular docking of TRPM8 with its sites of manifestation of the biological effect: R1008 (phenylalanine 1008) and L1009 (alanine 1009). About 10 potential ligands were predicted, which were further verified by the \"AUTODOCK\" method. Intermolecular docking, carried out using the AUTODOCK program, was carried out in coordinates for each of the sites set in the closest position to the docking point. The program identified the potential for successful interactions for eight out of ten predicted candidates for each of the sites. Two of the predicted ligands do not have the ability to successfully interact with TRPM8, the rest showed a high minimum binding energy and the number of reactive conformations compared to the classical ligand, menthol. In this work, we used the method of in silico selection of ligands using deep neural network, with further verification by the AUTODOCK program. This method will speed up the search for potential medicinal substances in the future.","PeriodicalId":201402,"journal":{"name":"2020 Science and Artificial Intelligence conference (S.A.I.ence)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133786088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
