Thematic search for information is an important problem now. The search for specialists can be called the most difficult direction for thematic search. This direction needs to be developed in many areas of activity. At the beginning of the article, a brief overview of existing approaches to solving this problem is given. The following is a list of existing information systems for finding specialists and experts. The paper describes an algorithm developed for solving this problem. Approbation of the algorithm is implemented on the data of the scientometric system IAS ISTINA, which has been used since 2012 to collect data on scientific activities at the Lomonosov Moscow State University. Thematic search uses data analysis of articles, reports and abstracts of conferences, monographs, dissertations, lectures and training courses. The following information about the objects of scientific activity is used: name of object; list of authors; keywords and annotations. The main features of the developed algorithm are: the search for specialists without their active participation in the search process, the ability to search in Russian and English; use all kind of scientific products for searching; additional definition of the authority of specialists in the co-authorship graph. The article describes the developed thematic search algorithm and the interface of its software implementation. This interface was created to test the algorithm on real data of the scientometric system ISTINA. In this interface, you can search by keywords with additional filtering by headings and view detailed information on the specialists found.
