vacancy_skills_data

3 datasets representing processed skill-sets for job advertisements obtained from HeadHunter online hiring platform (collected with open API https://dev.hh.ru/) for specialists in Information Technologies (in accordance with classifier https://github.com/hhru/api/blob/master/docs_eng/specializations.md). Description of main fields for vacancies is available via link https://github.com/hhru/api/blob/master/docs_eng/vacancies.md.<br><b>Datasets</b>:<br>1. "<i>vacancy_skill.csv</i>" - two column dataset, representing vacancy ID ("vacid") and processed skill name [in-demand skill] ("lv");<br>2. "<i>sh_soft_clusters.csv</i>" - three column dataset, representing initial formulations (translated) of "soft" skills ("V1"), the frequency of occurrence in the sample ("V2"), the etalon name [generalized categories of "soft" skills] ("ETALON");<br>3. "<i>jaccard_matrix.csv</i>" - dissimilarity square matrix between processed skill names (1,730 X 1,730) with Jaccard distances (computed by comparison of vacancy ID sets for each skill pair) [the first row and the first column contain skill names].

本数据集包含3份经标准化处理的岗位技能集数据，均采自HeadHunter在线招聘平台（通过公开API https://dev.hh.ru/ 采集），覆盖信息技术领域岗位（分类标准遵循 https://github.com/hhru/api/blob/master/docs_eng/specializations.md）。招聘启事核心字段的详细说明可通过链接 https://github.com/hhru/api/blob/master/docs_eng/vacancies.md 获取。<br><b>数据集详情</b>：<br>1. **`vacancy_skill.csv`**：该数据集包含两列，分别为岗位ID（"vacid"）与经处理的岗位刚需技能名称（"lv"）。<br>2. **`sh_soft_clusters.csv`**：该数据集包含三列，分别为软技能的初始译写表述（"V1"）、其在样本中的出现频次（"V2"），以及软技能的标准化类别名称（"ETALON"）。<br>3. **`jaccard_matrix.csv`**：该文件为处理后技能名称间的相异性平方矩阵（1730 × 1730），采用杰卡德距离（Jaccard distance）计算（通过比对每对技能对应的岗位ID集合得到），矩阵的首行与首列均为技能名称。
