WIPO Patent Application WO/2022/108206
Kind Code:
A1
Abstract:
Disclosed are a method and apparatus for completing a describable knowledge graph. According to the present invention, provided is the apparatus for completing a describable knowledge graph, comprising: a processor; and a memory connected to the processor, wherein the memory stores program instructions executable by the processor to: extract a plurality of relation paths for connecting a subject and an object in a query triple including the subject, a predicate, and the object; generate a plurality of describable segments by using the extracted plurality of relation paths; extract an embedding vector for each of the generated plurality of describable segments by using a neural network model in which a CNN and an LSTM are combined; compare the semantic similarity between the plurality of describable segments represented by the embedding vector and the query predicate included in the query triple, by using an attention mechanism; and determine a segment having high importance for link prediction regarding the query triple from among the plurality of describable segments via the semantic similarity comparison.
