Sentiment
Every page and document in your Opensolr Index carries a tone score: how positive, how neutral and how negative it reads, plus one overall score from -1 (very negative) to +1 (very positive).
Use it to let visitors keep only the positive reviews, to find the complaints in a support archive, or to watch the tone of a news site.
What is measured
The title, the description and the start of the text, for crawled pages and pushed documents alike. The tone is measured for English text.
Four numbers are stored with each document:
| Field | What it holds |
|---|---|
sent_com | The overall score, from -1 to +1 |
sent_pos | The positive share of the text |
sent_neu | The neutral share |
sent_neg | The negative share |
Turn it into a filter

Ask the chat bot
The chat bot command /language tells the language and the tone of any text you paste: positive, negative or neutral, with the overall score. See Chat bot commands.
