Borderline personality disorder (BPD) is characterized by impulsivity, emotion dysregulation, disturbed relationships, and identity disturbances. Despite the known variable co-occurrence of BPD symptoms, the possible causal relationships are not well understood. We addressed this by creating a hierarchical network model of BPD, which identifies the most likely acyclic causal pathways that are driving BPD development. Cross-sectional data was obtained from the Structured Clinical Interview-II (SCID-II), and possible causal relationships between symptoms were identified from conditional independence relations. The symptoms’ hierarchy values, assessing their role in causal pathways, was determined by a random walk-based algorithm. By analyzing the directed network of BPD symptoms, it was found that symptoms in initial stages of causal pathways were abandonment, physical fights, impulsivity, suicidal threats, identity disturbances, and affective instability. Based on the assessed role symptoms play in causal pathways of BPD development, specific symptoms can be targeted during early diagnosis and clinical assessment.

The article proposes an approach to determining the hierarchical network model of information provision representation of the submitted domain. The hierarchical network model represents the interconnection of information objects by subordination levels. One of the key issues in the development of information provision is the choice of the content delivery model in such a way as to ensure the most effective work with it as a user and developer. There are two main approaches - empirical and theoretical. The first is based on the study of the organization principles of human memory and the simulation of solving human problems mechanisms. The second approach can be defined as theoretically substantiated, which guarantees the correctness of the solutions, and the corresponding models - formal models of presentation of knowledge. The sequence of application of materials is included in the model, since the effectiveness of the perception of the material depends, among other things, on how much the person is "ready" to perceive the proposed information, that is, has a rather basic knowledge. Depending on the type of input data, possible ways of forming hierarchical network models of information support are proposed. If the input data is represented by a plurality of information elements, the number of which is relatively small and possible for the application of expert methods, the algorithm for constructing a hierarchical network two-level model of information provision is proposed. If the input data is represented by the "Tree of Knowledge", that is, the hierarchical model of information support, the algorithm for constructing a hierarchical network model is proposed. The hierarchical network model of information support, designed to manage the processes of acquisition and use of knowledge, which allows you to take into account the usefulness of information elements and didactic connections between them. The method of information support formation is proposed for the hierarchical network representation of the subject area, which allows to structure the information content and reference and other systems, which differ from the known of selection interrelated stages, clustering and content streamlining. The obtained results can be used to support decision-making in the acquisition and application of knowledge: in developing programs of individual advanced training courses; informational support of electronic learning systems; when forming distant education programs; in the development and subsequent adjustment of curricula; the formation of educational, reference materials, lecture courses for individual disciplines.
