Table retrieval method for engineering standard specifications with correlated semantic information
摘要
Abstract
According to the characteristics of tables in engineering standard specifications,a method is proposed to achieve automatic retrieval of their associated tables via query sentences by constructing a concentration joint repre-sentation between query sentences and multiple attributes of tables.Firstly,the concentration vector is obtained by calculating the pre-concentration between the keywords of the query and the attributes of the table title,table header and cells.Subsequently,the joint vector of query and tables is obtained by the bidirectional long short term memory network(Bi-LSTM)and multi-headed self-attention(MHA).Then,the concentration-joint representation between query and tables is constructed by fusing the concentration vector with the joint vector.Finally,the concentration-joint vector is input to the single-layer perceptron to obtain the similarity between query and tables.Experimental verification is carried out on the publicly available Chinese table datasets and constructed table datasets of engineer-ing fields,which shows that the proposed method has significant superiority in retrieval accuracy.关键词
