How to Choose a Provider to Outsource Text Annotation

Annotation, as we perhaps know, is the act of adding information to data that makes it meaningful and easy to understand. In other words, we enhance the data by annotating it. When this enhancement is done for data that is textual, we refer to it as ‘text annotation.’ But this is in English. The reference point here is enhancement of data so that it can be understood by computers. It is generally done as an input to building an Artificial Intelligence (AI) engine through a process of Machine learning (ML). What do we mean by ‘text annotation’ in this context? Let us take an example. Of Resume parsing. The context here is employment. Traditionally, the first step, when an employer sought to fill a position, was to request interested candidates to submit a Resume. The Resume, once submitted, would be perused by the HR team to ascertain suitability based on which it would be taken forward for further processing. This has been a manual, resource-hungry task for decades. With increasing volumes and pressure on performance, employers looked for technology solutions. As technology developed, in order to make processing more efficient, employers developed a database into which interested candidates could directly input their particulars, that would otherwise be submitted by means of a Resume. While this created efficiency for the employer, as they were able to sort, evaluate and process much faster and more accurately, it created additional work for the candidate. She had to input the information already present on her Resume, into a new database. And perhaps as many times as the jobs she was applying to. Enter AI. Leading to the evolution of Resume Parsing. What is the process now? Instead of keying in information field by field on the employer database, the candidate has to upload a copy of her Resume. The employer has a Resume parser at work which reads the information on the Resume and fills up the database fields by itself, only for a final assent by the candidate that she agrees with the final outcome. It is perhaps limited to large employers currently but adoption is rapidly increasing. This has been made possible through ML for which inputs have been created with the help of text annotation provider. Human text annotators have annotated thousands and millions of Resumes to identify what part of the text should be placed in which field of a manpower database. After being trained with enough data and with enough variations, the AI engine used by the employer can read the next Resume that gets submitted, and correctly classify it, even though it has not been annotated by a human being. This is the contribution of text annotation outsourcing to AI and ML. In more technical terms, it can be referred to as the addition of metadata to text so that it becomes meaningful for machines to read (or view) and understand. And, of course, it needs to be done by human hand. Text annotation being a critical input for AI and ML, for an outsourcer, it is important to ensure that they have the right and reliable partner to outsource text annotation. The ensuing paragraphs suggest a set of criteria based on which the selection should be made and questions that should be asked during the evaluation process. This would enable you to separate the grain from the chaff and select suitable provider/s out of a long list. To make the process simple, for each criteria, a set of questions is listed that an outsourcer should be asking vendors interested in providing text annotation outsourcing to them. These are neither mandatory nor sequential but meant as an indicative set to display the range that you might need to cover during the evaluation process. Depending upon the work that is being outsourced, you may need to shift your emphasis, leave out questions that may not be relevant and, at times, perhaps even go beyond this set. So, here we go.
