Аннотация

In this paper we address the problem of automatic extraction of facts from Russian texts. The facts under examination are the intentions of social network users to purchase certain goods or use certain services. The utilized approach is machine learning with annotation. A training set for expert annotation consists of messages from the “VKontakte” social network, selected through the LeadScanner API. The invented system of semantic tags allows distinguishing between various intentional blocks: objects, their different properties and emphatic constructions. Pre-processing of the training set includes lemmatization and grammatical tagging with PyMorphy2. Then, on the material of the training set, a directed graph is constructed. Each node in this graph corresponds to an intentional block, including information about its expertly-assigned intentional tag, grammatical and/or lexical properties of its main word. The edges of the graph connect the intentional blocks that can be found in adjacent positions across all the messages of the training set. Extraction of intention objects and their properties is achieved by test set analysis in accordance to the constructed graph. Test set includes both messages containing non-consumer intentions or no intentions at all. The precision and recall of intention extraction with macro average is 82% and 74% respectively.
