    The Text Annotation Tool For Teams

    Your product is designed very well - congrats! We have teams of annotators and i know how difficult it can be if the ux isnt easy to navigate - thanks for being thoughtful of that! Seing how much work would need to be manually tagged, our approach of having a rule-based tokenizer is a wise decision, and LightTag's ability to import them is an awesome feature! We looked at just about every product we could find when we decided we needed to in-house our NER.

    LightTag was the only candidate that was handling the management of multiple annotators well a must for us given the scale and speed we need. On top of that, the SaaS option let us get started without any building on our side, which meant our engineering resources could stay focussed on their primary goals.

    LightTag is an excellent extension of our machine learning team. Thanks so much for all the help and support during the labeling project! It is such a great tool! We have found LightTag to be the best software for marking up our voluminous corpus of Buddhist eTexts so that we can can eventually use AI to automate much of our metadata production and also for the creation of a corpus-derived dictionary tool.

Some processes and industries are harder to change, especially those that have been around for a long time. Court systems in many countries are one of the oldest and most well established processes to ensure all-around fairness, even if it must sacrifice expediency. Thankfully, the legal industry has taken major strides towards adapting to the digital age with the evolution of eDiscovery and document imaging.

When we think about OCR, we inevitably think of lots of paperwork - bank cheques and legal documents, ID cards and street signs. In this blog post, we will try to predict the text present in number plate images. What we are dealing with is an optical character recognition library that leverages deep learning and attention mechanism to make predictions about what a particular character or word in an image is, if there is one at all.

    Lots of big words thrown there, so we'll take it step by step and explore the state of OCR technology and different approaches used for these tasks.

    Optical character recognition or OCR refers to a set of computer vision problems that require us to convert images of digital or hand-written text images to machine readable text in a form your computer can process, store and edit as a text file or as a part of a data entry and manipulation software. The images can include documents, invoices, legal forms, ID cards or OCR in the wild like reading street signs, shipping container numbers or vehicle number plates. People have tried solving the OCR problem with several conventional computer vision techniques like image filters, contour detection and image classification which performed well on narrow, template based datasets which did not vary much in their orientation, image quality, etc but to make our models robust to these variations so that a business can deploy their machine learning applications at scale, new methods have to be explored.

    There are a lot of services and ocr softwares that perform differently on different kinds of OCR tasks.

    Deep learning approaches have improved over the last few years, reviving an interest in the OCR problem, where neural networks can be used to combine the tasks of localizing text in an image along with understanding what the text is. Using deep convolutional neural architectures and attention mechanisms and recurrent networks have gone a long way in this regard.

    One of these deep learning approaches is the basis of Attention - OCR, the library we are going to be using to predict the text in number plate images. Think of it like this. The overall pipeline for many architectures for OCR tasks follow this template - a convolutional network to extract image features as encoded vectors followed by a recurrent network that uses these encoded features to predict where each of the letters in the image text might be and what they are.

    You might be aware of RNNs or LSTMsneural network architectures that predict output at each time step, providing us with sequence generation as we need for language.

    This breed of neural networks intended to learn patterns in sequential data by modifying their current state based on current input and previous states iteratively.

    But due to limitations on memory and issues like vanishing gradientswe found RNNs and LSTMs not able to really capture the influence of words farther away. Attention mechanism tries to fix this.

    It is a way to get your model learn long range dependencies in a sequence and has found several applications in natural language processing and machine translation.

    24 Best Image Annotation Tools for Computer Vision

    In a nutshell, attention is a feed-forward layer with trainable weights that help us capture the relationships between different elements of sequences. It works by using query, key and value matrices, passing the input embeddings through a series of operations and getting an encoded representation of our original input sequence. There are flavors to attention mechanisms. They can be hard or soft attention depending on whether the entire image is available to the attention or only a patch.

    Having soft attention by laying each patch smoothly over the sequence makes it differentiable, but hurts the time taken to run computations. A better explanation can be found here. The secret sauce is the different ways of applying transformers.

    If you understand how attention works, it shouldn't take much effort to grasp how transformers work. In essence, the paper uses multi-headed attention, which is nothing but using several query, key and value matrices and training them independently, concatenating them and then extracting a useable matrix for our following network by using an additional set of weights.The Advanced Image Annotation Tool is for everyone from photography enthusiasts to small to mid sized businesses that wish to manage image documents by saving and retrieving them on a file system.

    This tool can get your images from your scanner or digital camera. The images may be OCR'ed and you can add other relevant information to the image itself for later searches that ensure quick and easy retrieval.

    Because the images are saved directly to the file system with the data safely contained in the image itself, they may be archived, backed up or shared easily. Microsoft Desktop Search may be used to retrieve images from the text descriptions added to the images. Anyone may view an image with this tool and see the data contained within.
