+# class-zbmath-identifier
+
+This is a proxy dataset to model semantic similarity of short mathematical texts from [zbMath](https://zbMath.org).This proxy only contains zbMath.org identifiers (aka an) instead of full titles / abstracts.
+
+## Columns
+
+* **an_a** (*string*): zbMath.org identifier of work *a*
+* **MSC_a** (*string*): primary MSC<sub>5</sub> of work *a*
+* **MSC2_a** (*list(string)*): secondary MSC<sub>5</sub>s of work *a*
+* **an_b** (*string*): zbMath.org identifier of work *b*
+* **MSC_b** (*string*): primary MSC<sub>5</sub> of work *b*
+* **MSC2_b** (*list(string)*): secondary MSC<sub>5</sub>s of work *b*
+* **label** (*bool*):
+  * **1**: semantically similar texts
+  * **0**: semantically dissimilar texts
+
+
+
+The label is based on the MSC and MSC2 classification codes. If **MSC_a** and **MSC_b** are equal and **MSC2_a** and **MSC2_b** overlap in at least one code, works are defined as semantically similar.
