Using a CV or vacancy parser based on Named Entity Recognition (NER) can complement and enhance the adoption of large language models (LLMs) in several ways and provide advantages over using LLMs alone. Here's how it can accelerate adoption of LLMs and be a better solution:

Data Preprocessing

CV or vacancy parsers based on NER can serve as a preprocessing step to extract structured information from resumes or job listings. They can identify and label specific entities such as job titles, skills, education details, work experience, and contact information. By extracting structured data, the parser can provide cleaner and more organized input to LLMs, which can then focus on higher-level understanding and generation tasks.

Data Augmentation

CV or vacancy parsers can generate labeled training data for fine-tuning LLMs. By using the parser to extract named entities from a large corpus of resumes or job listings, one can create additional labeled examples for training LLMs specifically for the job application domain. This data augmentation technique can help improve the performance of LLMs by providing domain-specific training signals.

Custom Entity Recognition

CV or vacancy parsers can be designed to recognize domain-specific entities that are not typically covered by general-purpose LLMs. For example, in the context of recruitment, specific entities like salary expectations, project details, or specific industry-related keywords can be identified by the parser. This custom entity recognition helps address the unique requirements of the job application domain and enables more precise information extraction compared to LLMs that may not have been trained specifically for this domain.

Efficiency and Scalability

NER-based parsers are often more efficient in terms of computational resources and processing time compared to large language models. By offloading the task of entity recognition to a dedicated parser, the overall system can be more scalable, enabling faster processing of large volumes of resumes or job listings. This efficiency is particularly advantageous in applications that require real-time or near-real-time processing, such as automated recruitment platforms.

Domain-Specific Knowledge

CV or vacancy parsers can incorporate domain-specific knowledge and rules to improve entity recognition accuracy. They can be trained or fine-tuned using domain-specific data, allowing the parser to capture job-specific terminology, abbreviations, and variations in resume formats. This domain-specific knowledge ensures higher precision in extracting relevant entities compared to LLMs that have a more generalized understanding of language.

By combining the strengths of CV or vacancy parsers based on NER with the capabilities of LLMs, adoption of LLMs can be accelerated and the overall solution can be more effective. The parser acts as a specialized tool to preprocess and extract structured information, improving the quality and relevance of the input data for LLMs. Together, they provide a more powerful and tailored solution for understanding, generating, and processing job-related text data.
