What are the features of job and resume ranking?

Job and resume ranking is the task of sorting and evaluating the relevance of documents (job postings or resumes) based on a user's query. Features include:

• Multifactorial: various attributes are considered — keywords, experience, skills, geography, salary expectations.
• Use of Learning to Rank (LTR) models: trainable models that establish the optimal order of results based on multiple features.
• Handling synonyms and variations: NLP techniques are applied to improve search quality.
• Personalization: user preferences and history are taken into account.
• Balance between accuracy and diversity: to avoid showing too similar job postings or resumes consecutively.

Thus, ranking is a complex process that combines classical information retrieval methods with modern ML approaches to enhance the quality of selection.
