I have a large collection of strings that each contain information about a
certain product. For example:
wine Bardolo red 1L 12b 12%
La Tulipe, 13* box 3 bottles, 2005
Great Johnny Walker 7CL 22% red label
Wisky Jonny Walken .7 Red limited editon
The number of product names is limited, as are most other properties, but
they might be misspelled.
I would like to extract keywords from all those strings. Product name,
product type, volume, etc. But I'm not sure what the best approach would be
and if ElasticSearch would be the tool of choice. I've looked at
PostgreSQL's trigram plugin (pg_tgrm) since all data sits in a PostgreSQL
db at the moment, but that seems limited. I was thinking about creating
some kind of master list of proper keyword and try to match words from a
string with those keywords. These words could be misspelled meaning they
would have to be:
- fuzzy matched
- matched by hand
- match by some sort of neural network trained with existing data
Someone suggested "analyzing the entire string as an ngram using the ngram
tokenizer", but I'm not sure. Any pointers where I should direct my effort
would be highly appreciated!
