An algorithm for the bit-string encoding of objects described by discrete attributes with a binary similarity operation on each attribute value is proposed and analyzed. In this encoding, the bitwise multiplication operation must correspond to the componentwise similarity operation.

Scientometric analysis of a rapidly developing interdisciplinary area that covers problems of the creation and development of quantum technologies is carried out. General characteristics of the subject are given and key areas of research are identified. The publication activities of different countries are evaluated for the 2000–2016 period based on the analysis of papers indexed in the Web of Science database. The leading countries (United States and China) are determined. The most actively progressing research areas are considered. A short-term prediction on the expected number of publications for the United States and China is made. Particular attention is paid to the publication activities of Russian scientists on subject categories of the Web of Science index. The intensity of international cooperation in the field of quantum technologies and the degree of internationalization of research are studied.

One of the tools for the semantic enrichment of the content of information resources is semantic annotating, which makes it possible to comment on and evaluate annotated resources and their fragments and to carry out a semantic search on their basis. The use of the taxonomic approach simultaneously allows classifying the subjects of annotating and generating new scientometric indicators. This paper considers the essence of semantic annotating, defines the basic concepts, discusses the general model of semantic annotation and taxonomic approach to presenting the semantics of annotations, and gives the examples of taxonomies based on various properties of annotations. The implementation of semantic annotating in the Socionet scientific information system is considered as an example.
