Embodiment Construction
[0032] The present invention will be further described below in conjunction with the accompanying drawings.
[0033] Such as figure 1 As shown, the present invention proposes an entity relationship extraction method for automatically constructing a data set, including the following processes:
[0034] Step 1, carrying out the collection and preprocessing of corpus;
[0035] Step 2, define a triple dictionary table, and build a synonym table;
[0036] Step 3, using the LTP tool to generate a training data set and a test data set;
[0037] Step 4, training the network model according to the training data set;
[0038] Step 5. Perform entity and relationship prediction on the test data set through the trained network model;
[0039] Step 6. Optimizing the prediction results to obtain a triplet data set.
[0040] specific,
[0041] In step 1, crawler data and undisclosed document data are mainly collected, the collected multi-source heterogeneous data is cleaned up, and fina...
