Smart Ranking and Customized Results
The relevance in vLex is calculated by combining several technologies and exclusive algorithms:
- Textual Ranking. Shows documents where the searched terms have more importance (more occurrences and key fragments).
- Legal Ranking. Gives priority to results from sources of higher legal status: thus, a result of a higher court will have more priority over a minor court, same applies to a law over a decree, that is, the law will have more priority over the decree.
- Ranking by citation graph. The system analyzes citations from legal documents, and gives more ranking to those documents that are more frequently cited, especially those that are cited by important and recent documents.
- Social ranking. Analyzes the behavior of users by identifying signs that a document has been a good result (for example: printing the document, downloading, sending by e-mail, etc.) or that it has been a bad result (“bounce rate”: immediately go back to the search and click on another result). It uses repeated searches to identify which documents are preferred by users and gives those documents a more prominent place. As more users continue to use the system, it learns, giving more relevant results and adapting the results rankings as the legal and social environment evolves.
- Personal ranking. Analyzes your personal conduct, using the SmartTopics and subscribed documents as indicators.
- Editorial ranking. For the most frequent searches our documentary team manually selects the key search results for that term.
In addition to organizing the search results by relevance (default option) you also have the ability to select how you want your search results organized. The available criteria are:
- Sort by date (most recent or oldest)
- Sort by popularity. We organize the results based on the success of the search among vLex users (social ranking)
- Sort by number of citations. This option is only available in Canada
