The article describes all stages of the development of an Information system for the creation, development and support of scientific research in geology: from the Information and analytical environment to the Unified Digital Space of geological scientific knowledge. The current stage of the Project under development is a step forward from the traditional geographically distributed geological system to the digital environment of the future.

The article describes the main stages of the application of information technologies for scientific research in geology. A number of digital technologies of the near future, which currently have prospects for application in geology, are considered. The first results of the work at the GGM RAS showed the prospects of applying the next steps in the development of OT technologies in the creation of information and computing systems to support geological research.

Series of Conferences took place on the modern information technologies in the Earth Sciences in Russian Far East. This publication represents the historical review of these Conferences.

This work is related to the development of a high-tech popular science Internet portal "History of the Earth". The developed resource sets as its main goal the popularization of modern scientific geological knowledge using popular science multimedia content and software tools for interactive work with it. The Internet resource is intended for schoolchildren and students, as well as a wide range of Internet users.

A brief overview of some methods of artificial intelligence in the field of Earth sciences is given. The prospects of using these methods to obtain new knowledge are noted. The results of the authors' first attempts to apply natural language processing methods for processing scientific articles on geology are presented. The possibilities of developing work in this direction are discussed.

A new approach related to the extraction of terms of relative geological age from the metadata of scientific geological publications is described. Based on the developed and adapted approaches and technological solutions, a set of macros is implemented that implements the functions of searching, extracting and adding new metadata to scientific publications.

The article describes the role of museum data in scientific geological research, as well as the integration of this data into the digital space of geological knowledge for more efficient use and analysis of distributed geological and museum resources and the possibility of building digital models.

The article describes new approaches related to the collection of data from heterogeneous information systems of access to scientific publications using open international standards and protocols for the formation of systems of open access to scientific geological publications. Based on developed and adapted approaches and technological solutions, a set of programs of information and analytical system of access to scientific publications has been implemented, implementing functions of collection, search, cataloguing, filtering and management of scientific publications and their metadata.

The article describes the use of information technologies and modern means of digitalization in organizing and holding a Conference on IT in Earth Sciences. Modern aspects of visualization are also described in the reports of the Conference participants.

The materials presented at the Conference describe the results of recent years in the following areas: Open access to scientific data and knowledge in Earth Sciences; Data peculiarities in Earth Sciences: new concepts and methods, tools for their collection, integration and processing in different information systems, including systems with intensive use of data; Data mining and mathematical simulation of natural processes in Earth Sciences. Evolution of classical GIS-applications in Earth Sciences; Application to Critical Raw Materials (CRM); social aspects of mining (e.g., the Social Licence to Operate [SLO]); predictive mapping and applications to exploration, landuse and search for extensions of known deposits; Intelligent data analysis, elicitation of facts and knowledge from scientific publications. Thesauruses, ontologies and conceptual modeling. Semantic WEB, linked data. Services. Content semantic structuring. Applications for geosciences, e.g., Ontology-based Dynamic Decision Graphs for Expert systems and decision-aid tools; Application of methods and technologies of the remote sensing in Earth Sciences: from satellites to unmanned aerial vehicles; Information technologies for demonstration and popularization of scientific achievements in Earth Sciences; Applications: environmental risks including mining wastes, natural hazards, water resource management, etc.

This paper discusses heterogeneous geographically distributed computing systems for processing geological data and approaches to organizing interaction with these systems. The systems are classified by the authors into a number of groups based on the main functional capabilities and technological solutions. A description of the main properties for each type of systems is given, including possible ways for interaction.

An approach is proposed for organizing a single workspace with access to heterogeneous geographically distributed computing systems within the ecosystem developed by the authors. The architecture of the proposed solution and the rules of interaction for its participants are described. A software prototype is demonstrated that implements the described principles on the example of several heterogeneous systems for processing geological information.

The paper describes new approaches to collecting data on scientific publications from open access systems with the subject of Earth Science. Based on the developed and adapted approaches, an archive of scientific publications (repository) and a set of programs for accessing scientific publications for collecting, searching, filtering, cataloging and managing publications and their metadata have been created. In order to improve the availability of publications and other related data on the websites of the SGM RAS, the Wiki – Geology of Russia system has been developed. This system is a thematic rubric in the direction of "Mineral deposits of Russia", with an additional topic "Mineralogy". All articles must have a link to the source of information from the archive of scientific publications and, optionally, additional links on similar topics. Wiki – Geology of Russia is the first step in creating a knowledge base on mineral deposits.

The aggregation of scientific information is essential for a comprehensive analysis of geological objects. This paper explores the potential and possibilities of semantic search to select thematically similar publications in the geological domain. Various language models are examined in the context of identifying similarities and differences in texts describing mineral deposits. After additional training of language models, a significant improvement in search results is demonstrated. Two web services are presented, based on a method for calculating the semantic similarity between texts and providing a quantitative assessment of their similarity.
