- With the development of technology, the keyword-based detection mechanism is insufficient due to the extraction of large amounts of irrelevant information. This article proposes a semantic search engine. In view of this, the algorithm of a search engine based on voice search based on a conceptual search engine that receives a user request through voice is described. This query is converted to text using an intelligent multimodal interface, which, based on the ontological search in the semantic network, allows you to get an accurate result.

- Many experts predict that the next huge step forward in web information technology will be achieved by adding semantics to web data and possibly consist of a semantic network. This article presents an approach to semantic search that combines standard web search with ontological knowledge. In fact, this article is devoted to the use of standard search engines as the main method of data output for ontology search. In this paper, we propose to use lightweight software clients for annotation and query parsing. It also develops a formal model that can be implemented in an intelligent multimodal interface. In addition, it presents the results of experiments proving the possibility of using this approach for the analysis of very large amounts of data.

- In recent years, extensive research is aimed at creating a semantic network as a future form of the internet. Web search as a key technology of the internet is evolving into a new form of search in the semantic internet. A promising approach to such semantic search on the internet is based on combining standard search engines as the main output of semantic search results. This paper proposes an improved approach to semantic search. This includes the ability to handle inconsistencies, noise and incompleteness that are likely to occur in distributed and heterogeneous environments such as the internet.

- To determine the effect of dispersed reinforcement on the properties of concrete requires the construction of adequate mathematical models. The article discusses the mathematical basis for taking into account the effect of dispersed reinforcement on the hardening of concrete, taking into account the geometric dimensions of the structure. The coefficients of orientational attenuation of the deformation of the fiber with an isotropic distribution of fibers and taking into account the effect of constraint are obtained. An improved model of random deformations of a thin fiber during mixing is given. Technological proposals have been developed to increase the strength of products and structures made of fibrous concrete due to an increase in the concentration of fiber in the surface layer by pressing.
