Popis pozice

The project team is researching various approaches to detecting explicit and potential duplicates in text written in the IDE in natural languages (English to start with). 

Our IntelliJ plugin helps streamline the process of writing technical documentation for a software application inside the IDE. It supports the concept of ‘single source’, which means that a chunk of content can be written once and re-used in multiple help articles or documentation outputs by including it by ID. 

The proposed inspection should be able to detect identical pieces of content, or, more importantly non-explicit duplicates so that they can be extracted to a library and reused. Such inspection should help:

  • maintain consistency throughout sources
  • avoid making multiple updates when an UI changes
  • reduce on the review and editing effort
  • reduce on localization costs

Comparing each chunk of text with all other chunks and suggesting duplicates based on the percentage of matches is not a task that can be run in the IDE at runtime on a large code base, so we expect you to research, try and test different approaches that may include ML, Elasticsearch, trigram search, the Apache Lucene engine, and whatever other approaches you can apply.

As a result of the internship project, we would expect you to: 

  • Create an inspection that can be run in the IDE or in an external web interface in the headless mode and provide data on the potential duplicates
  • An intention action in the IDE that would suggest extracting such duplicates to reusable chunks
  • An inspection that would analyze duplicates in the background and suggest replacing content with an existing chunk as you type (ideally)
