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份经预处理的岗位技能集数据，采自HeadHunter在线招聘平台（通过公开API https://dev.hh.ru/ 采集），覆盖信息技术领域专业人才岗位（分类标准遵循 https://github.com/hhru/api/blob/master/docs_eng/specializations.md）。岗位招聘信息的主要字段说明可通过链接 https://github.com/hhru/api/blob/master/docs_eng/vacancies.md 查询。 **数据集**： 1. *vacancy_skill.csv*：该数据集共两列，分别为岗位ID（"vacid"）与经预处理的刚需技能名称（"lv"）； 2. *sh_soft_clusters.csv*：该数据集共三列，分别为“软技能”的原始表述（已完成翻译，"V1"）、在样本中的出现频次（"V2"）以及软技能广义分类的标准名称（"ETALON"）； 3. *jaccard_matrix.csv*：该文件为经预处理的技能名称间的相异性方阵（1730×1730），采用杰卡德距离（Jaccard Distance）计算，计算逻辑为比对每对技能对应的岗位ID集合，矩阵的首行与首列包含技能名称。
