An information extraction support device includes a receptor, a pattern generator, a data generator, and an output controller. The receptor receives input of a first training example for learning a model used in at least one of extraction of information and extraction of a relation between a plurality of pieces of information, and clue information indicating a basis on which the first training example is used for learning. The pattern generator generates a supervised pattern for generating a training example used for learning, using the first training example and the clue information. The data generator generates a second training example using the supervised pattern. The output controller outputs the second training example and the clue information that is used to generate the supervised pattern having generated the second training example.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. An information extraction support device, comprising: one or more hardware processors configured to receive input of a first training example for learning a model used in at least one of extraction of information or extraction of a relation between a plurality of pieces of information; receive clue information indicating a basis of using the first training example for learning; generate a supervised pattern for generating a training example used for learning using the first training example and the clue information; generate a second training example using the supervised pattern; and output the second training example and the clue information that is used to generate the supervised pattern. 2. The information extraction support device according to claim 1, wherein the one or more hardware processors are further configured to receive input of a determination result indicating whether the second training example is correct, and the one or more hardware processors are further configured to update the generated supervised pattern based on the determination result. 3. The information extraction support device according to claim 2, wherein the one or more hardware processors are further configured to generate a third training example using the updated supervised pattern, and the one or more hardware processors are further configured to output a difference between the second training example and the third training example. 4. The information extraction support device according to claim 1, wherein the one or more hardware processors are further configured to receive a keyword used for searching information including the first training example as the clue information. 5. The information extraction support device according to claim 1, wherein the supervised pattern is a pattern for generating a training example and a determination result indicating whether the training example is correct, the one or more hardware processors are further configured to generate, using the supervised pattern, the second training example and a determination result of the second training example, and the one or more hardware processors are further configured to associate the supervised pattern with the determination result of the second training example generated using the supervised pattern and to output the associated result. 6. The information extraction support device according to claim 1, wherein the supervised pattern defines a condition to be satisfied by a training example used for learning, and the one or more hardware processors are further configured to generate the second training example satisfying the condition. 7. The information extraction support device according to claim 1, wherein the one or more hardware processors are further configured to generate the supervised pattern to which a degree of importance is associated, and the one or more hardware processors are further configured to change the supervised pattern generating the second training example in accordance with the degree of importance. 8. The information extraction support device according to claim 1, wherein the one or more hardware processors are further configured to learn the model using at least one of the second training example and a training example newly generated using the supervised pattern. 9. The information extraction support device according to claim 1, wherein the one or more hardware processors are further configured to output another training example with the same or similar clue information as the second training example. 10. An information extraction support method, comprising: receiving input of a first training example for learning a model used in at least one of extraction of information or extraction of a relation between a plurality of pieces of information; receiving clue information indicating a basis of using the first training example for learning; generating a supervised pattern for generating a training example used for learning using the first training example and the clue information; generating a second training example using the supervised pattern; and outputting the second training example and the clue information that is used to generate the supervised pattern. 11. A computer program product having a non-transitory computer readable medium including programmed instructions, wherein the instructions, when executed by a computer, causing the computer to perform operations comprising: receiving input of a first training example for learning a model used in at least one of extraction of information or extraction of a relation between a plurality of pieces of information; receiving clue information indicating a basis of using the first training example for learning; generating a supervised pattern for generating a training example used for learning using the first training example and the clue information; generating a second training example using the supervised pattern; and outputting the second training example and the clue information that is used to generate the supervised pattern.
