Dataset Card for "code_x_glue_cc_clone_detection_big_clone_bench"

Dataset Summary

CodeXGLUE Clone-detection-BigCloneBench dataset, available at

Given two codes as the input, the task is to do binary classification (0/1), where 1 stands for semantic equivalence and 0 for others. Models are evaluated by F1 score. The dataset we use is BigCloneBench and filtered following the paper Detecting Code Clones with Graph Neural Network and Flow-Augmented Abstract Syntax Tree.

Supported Tasks and Leaderboards

  • semantic-similarity-classification: The dataset can be used to train a model for classifying if two given java methods are cloens of each other.


  • Java programming language

Dataset Structure

Data Instances

An example of 'test' looks as follows.

    "func1": "    @Test(expected = GadgetException.class)\n    public void malformedGadgetSpecIsCachedAndThrows() throws Exception {\n        HttpRequest request = createCacheableRequest();\n        expect(pipeline.execute(request)).andReturn(new HttpResponse(\"malformed junk\")).once();\n        replay(pipeline);\n        try {\n            specFactory.getGadgetSpec(createContext(SPEC_URL, false));\n            fail(\"No exception thrown on bad parse\");\n        } catch (GadgetException e) {\n        }\n        specFactory.getGadgetSpec(createContext(SPEC_URL, false));\n    }\n", 
    "func2": "    public InputStream getInputStream() throws TGBrowserException {\n        try {\n            if (!this.isFolder()) {\n                URL url = new URL(this.url);\n                InputStream stream = url.openStream();\n                return stream;\n            }\n        } catch (Throwable throwable) {\n            throw new TGBrowserException(throwable);\n        }\n        return null;\n    }\n",

Data Fields

In the following each data field in go is explained for each config. The data fields are the same among all splits.


field name type description
id int32 Index of the sample
id1 int32 The first function id
id2 int32 The second function id
func1 string The full text of the first function
func2 string The full text of the second function
label bool 1 is the functions are not equivalent, 0 otherwise
