带词性和tf-idf词频统计小巧中文分词词库.rar

在我的工作中自己总结完善的停用词词典，包含一些无意义的词语，短语等。通过剔除文章中的停用词，你可以大大减少LDA,TF-IDF等算法中词典的大小

欧洲音乐发布数据库，这是国外意大利资源小组iDF 内部下载程序，在里面可以下载多达20000张世界舞曲专辑。

自己根据乐鑫官方文档，机器加人工翻译的文档，不周之处还望理解。相关ESP32的教程请移步博文，本人渣渣，错误之处，大佬抬一手？

esp32-freertos-sdk 工具包 See the Getting Started guide links above for a detailed setup guide. This is a quick reference for common commands when working with ESP-IDF projects: Setup Build Environment (See Getting Started guide for a full list of required steps with details.) Install host build dependencies mentioned in Getting Started guide. Add tools/ directory to the PATH Run python -m pip install -r requirements.txt to install Python dependencies Configuring the Project idf.py menuconfig Opens a text-based configuration menu for the project. Use up & down arrow keys to navigate the menu. Use Enter key to go into a submenu, Escape key to go out or to exit. Type ? to see a help screen. Enter key exits the help screen. Use Space key, or Y and N keys to enable (Yes) and disable (No) configuration items with checkboxes "[*]" Pressing ? while highlighting a configuration item displays help about that item. Type / to search the configuration items. Once done configuring, press Escape multiple times to exit and say "Yes" to save the new configuration when prompted. Compiling the Project idf.py build ... will compile app, bootloader and generate a partition table based on the config. Flashing the Project When the build finishes, it will print a command line to use esptool.py to flash the chip. However you can also do this automatically by running: idf.py -p PORT flash Replace PORT with the name of your serial port (like COM3 on Windows, /dev/ttyUSB0 on Linux, or /dev/cu.usbserial-X on MacOS. If the -p option is left out, idf.py flash will try to flash the first available serial port. This will flash the entire project (app, bootloader and partition table) to a new chip. The settings for serial port flashing can be configured with idf.py menuconfig. You don't need to run idf.py build before running idf.py flash, idf.py flash will automatically rebuild anything which needs it. Viewing Serial Output The idf.py monitor target uses the idf_monitor tool to display se

采用tf-idf算法计算携程评论中的关键词，并输出前500个关键词，该算法不同于市面上的其他算法，保证了o（n）的时间复杂度，执行速度更快，同时具有更好的移植性和健壮性

计算TF-IDF的程序，使用java编写，能计算出输入文档的TF-idf值

这是一个使用python实现TF-IDF算法的代码，具体介绍见本人博客

通过python代码实现TF-IDF算法，并对文本提取关键词，可以自己添加词库以及停用词表。
