信息检索与Web搜索

2 学分难度 超难👥 21 人学过

The course discusses the theory, design, and implementation of Information Retrieval (IR) techniques in text-based information systems. The theoretical component of the course focuses on IR methods for the processing, indexing, querying, ranking, organisation, and classification of textual documents, including Web documents. A variety of current research topics are also covered, including professional search and recommendation systems. The practical component of the course addresses the design and implementation of high-capacity text retrieval and filtering systems such as web search engines.

毕业生去向(整体)

下面是匠人学院毕业生整体去过的公司分布(来自脱敏校友证言)。这是全平台的总体去向,不代表选这门课的人一定去这些公司。

统计自 313 份脱敏校友证言

Deloitte

关于这块数据,我们说实话

雇主墙来自脱敏毕业生证言（testimonials）的整体分布，无法关联到具体学员或其所选课程；仅作为毕业生去向的总体社会证明展示。

我们没有"某位学长选了这门课、后来进了哪家公司"这种可查询的个人去向档案 —— 校友证言是脱敏的,无法关联到具体的人或他选过的课。所以这里只给整体分布,不给个人路径,不编。
