Structured Query Construction via Knowledge Graph Embedding
Table 2: Average time cost of each module
['Module', 'Avg.Time Cost (ms)']
The average time cost of our framework to construct the graph-structured query and obtain answers for a given NLQ is 601.4ms. The phrase mapping module spends much more time than the other modules due to the large scale of DBpedia which also increases the time cost of the query evaluation process.
