Database Generation¶

To create database, one should provide a CSV file of products. This file should contains columns 編號, 品牌, 中文品名, and 中文簡介. Next run ./util/database_generate.py. It will automatic generate setting files in <DATABASE>/etc/.

<DATABASE>/etc/brand0.txt

the list of brand aliases. Each line corresponds to the aliases of a brand, separated by spaces.

<DATABASE>/etc/head0.txt

the list of head words. Each line corresponds to a head. One may refer the automatically generated file head0.txt.auto for modification.

<DATABASE>/etc/compound0.txt

the list of head word compounds. Each line corresponds to a compound and its word segmentation, separated by a tab.

<DATABASE>/etc/core0.lex

the core lexicon. Each line corresponds to a word and (optional) its post-tag, separated by a tab.

<DATABASE>/etc/infix0.lex

the infix lexicon. Each line corresponds to a word and (optional) its post-tag, separated by a tab.

<DATABASE>/etc/product.head0

the list of product heads. Each line corresponds to a product ID and its head, separated by a tab. One may refer the automatically generated file product.head0.auto for modification.

<DATABASE>/etc/etc0.py

an extra script, executed after loading each product from the CSV file. The data of the product is store in:

self.pid: 編號

self.bname: 品牌

self.pname: 中文品名

self.descr: 中文簡介

Please manually modify above files. After modification, run ./util/database_generate.py again. Repeat modification and executing ./util/database_generate.py until there is no error message.
