[0040]Example 1
[0041]First of all, it needs to be explained that the present invention is a method for generating knowledge graphs for extracting information related to online resources. The purpose of this invention is to extract fine-grained information related to resources in the context sentences of online resource citations in scientific literature, and generate knowledge based on the extracted information. Atlas. Fine-grained information extraction includes the extraction of online resource-related technology entities and the extraction of the relationship between target resource entities and online resource-related technology entities. This problem has the following formal definition: Given a context sentence containing online resource references s={w1,w2,...,wN}, for example, the context sentence "We selectedour vocabulary from terms(words and phrases)in WordNet lexicon", N is the length of the sentence word sequence (in the example given above, the context sentence consists...

[0098](1) Experimental data settings
[0099]Before introducing the experimental data, firstly, the definition of the online resource-related scientific and technological entities and the resource-entity relationship as the object of fine-grained information extraction in the present invention is given.
[0100]For online resource-related technology entities related to target resource entities, there are six different entity categories, namely: Task, Method, Data, Metric, and Generic Term ). The detailed definition and examples of each technology entity category are as follows:
[0101]1) Task: includes the description of the scientific and technological entities that need to be solved, the system to be built, and specific application scenarios that can be completed as the goal.
[0102]For example.: Language modeling,relation classification,transductiveinference,tree parsing...
[0103]2) Method: Including algorithms, strategies, models, tools, software, code bases, frameworks, sys...
