WORK HISTORY
Consultant @Tekxt
Tekxt supplies both products and consultancy services for \"knowledge extraction\" from text and image documents. Algorithms are based on rule engines, agent simulations, data science and machine learning techniques.Building on extensive image processing, semantic search and matching experience tekxt was founded to help companies find, extract and process information contained in a variety of image and document sources.We also assist with technology vendor evaluation, selection and management.Tekxt also supplies pre-built API solutions that are available on a variety of cloud platforms for various types of knowledge extraction from documents.A selection of successful projects:Designed and implemented a system that given a technical document with images describing a data schema could scrape and OCR the images along with the directed lines. This image sourced document was verified and augmented with other data extracted from the documentation and produced a schema output in a variety of formats. Including a 3d view.Given a product (brandname and/or description) determine its correct tarriff code. This involved data augmentation, data science and advanced semantic understanding whilst still being performant.To assist field technicians to successfully complete an installation we created a natural language search engine that given a set of technical documentation could answer questions from the technician. This was a vast improvement over previous keyword only search methods.
