Description

technical field

[0001] The present invention relates to the field of information technology, in particular to a method, device and terminal for constructing a knowledge map of scientific and technological figures based on a deep learning model. Background technique

[0002] With the advent of the "big data" era, the amount of data available for research and analysis has exploded. However, most of these massive data are unstructured text data composed of natural language. Therefore, how to extract effective information from unstructured text information and form structured information that is easy to understand and store has become a research hotspot in recent years. .

[0003] To process text data with complex entity relationships, there are generally the following two steps. First, extract information from the text data, and then store the extracted knowledge in a structured manner for further processing and utilization. In terms of information extraction, there are extra...
