Keywords is our keyword extractor that identifies the "information carrying" words text.
Using free Japanese text as input, Keywords analyses and extracts the most important words in the text while leaving out uninteresting words.

Try hovering to highlight words in the below newspaper article excerpt.
The important words are highlighted in green, and their relative importance is indicated by colour intensity.
Keywords supports a range of important applications within search and analytics:
- Social media analytics. Understand the gist or dominant trend of what people are saying in social media about a given brand, company or topic across a large document set.
Searching by example. Instead of inputting a few terms that describe what you are looking
for, with Keywords you can provide sample passages of text (or whole documents) and have a large query
automatically built to match the provided content.
Negative examples are also possible. For example, give me documents about "apple", but I'm not interested in fruit so include some fruit articles as negative examples to make sure "fruity" articles will not be included in my search result.
These queries tend to be too hard for people to formulate themselves.
- Content based personalisation. Many personalisation approaches today are based on so-called collaborative filtering, i.e. personalisation based on events around an item or document, but doesn't take the content of the document itself into account. Keywords can be used to make content-based personalisation and recommendation systems.
