项目推荐的数据库管理

Question

I am collecting user review from my site. Review can have 1,2,3,4,5 rate.

From each review I am collceting list of adjectives. So I will have good, nice, great, excellent etc scrapped from these reviews.

Currently I am taking adjectives from review and storing into table. I append each new set of adjectives coming from reviewa with previous list.

Then I have seperate function call to which counts occurrence of each word and store into another table.

What I want:

I want to create review recommendation which grade the recommendation system based on adjective occurrence.

Depending on how many adjectives (good, great,nice etc) count review has, it will be ranked. Good in 4 star review has more value then good in 3 star review.

means displaying the best review (4-5 star) having maximum positive adjectives.

I am wondering how should I manage my database so that I can get rid of this in faster way.

any thought would be highly apprecited.

Answer 1

ok, I think making query - select review from table where max (good,nice,great) and business_type = 'xyz' order by review_rate desc; will do.

for max (good,nice,great) - selecting reviews from table in which contents adjective which have highest occurence. how can I make query for this?

I have seperate table which contains words and occurrence

word   count
-------------
good    463
great   345
nice    321
best    234
