Knowledge Graphs are applied in many fields such as search engines, semantic analysis, and question answering in recent years. However, there are many obstacles for building knowledge graphs as methodologies, data and tools. This paper introduces a novel methodology to build knowledge graph from heterogeneous documents.  We use the methodologies of Natural Language Processing and deep learning to build this graph. The knowledge graph can use in Question answering systems and Information retrieval especially in Computing domain

This article describes a method for composing fluent and complex natural language questions, while avoiding the standard pitfalls of free text queries. The method, based on Conceptual Authoring, is targeted at question-answering systems where reliability and transparency are critical, and where users cannot be expected to undergo extensive training in question composition. This scenario is found in most corporate domains, especially in applications that are risk-averse. We present a proof-of-concept system we have developed: a question-answering interface to a large repository of medical histories in the area of cancer. We show that the method allows users to successfully and reliably compose complex queries with minimal training.

The article is devoted to the application of the method of complex semantic-syntagmatic analysis of collocations, or combinatorially determined lexical and phraseological units, characterized by structural-semantic integrity and having functional, idio-ethnic and other limitations. The relevance of the work is due to the importance of their study as universal units inherent in all natural languages. The purpose of the article is to substantiate the advisability of using the method of complex analysis of collocations and with its help to identify the semantic, functional, syntagmatic mechanisms of their formation, as well as to discover the universal and specific characteristics of these units. The method is developed in the framework of combinatorial lexicology, studying the linear relations of words and their combinatorial potential. The novelty of the study is in the development of a detailed analysis technique, with the help of which it will be possible to detect the mechanisms of formation of various collocations. The material for study was colour collocations, which are created by the adjective type. An algorithm for performing complex analysis is presented, and the procedure for its implementation is demonstrated. Particular attention is paid to the semantic and combinatorial-syntagmatic blocks as the most important aspects of the study of the compatibility of lexemes in the framework of the combinatorial science of words.
