The text-tokenizer and the text_to_sequence functions hold a lot of untapped value. If you want to implement such a model in production environment, I would recommend playing with the text-preprocessing parameters. I am pretty sure that are better parameters to tune the model. I hope the short tutorial illustrated how to preprocess text in order to build a text-based deep-learning learning classifier. In the movies dataset each record represents a movie available on Rotten Tomatoes, with the URL used for the scraping, movie tile, description, genres, duration, director, actors, users ratings, and critics ratings. Layer_dense(units=num_classes, activation = 'softmax')įinally, we plot the training progress and conclude that it is possible to train a classifier without too much effort. Layer_dense(units = 512, input_shape = c(max_words), activation="relu") %>% So basically one builds a dictionary in which each index refers to a particular word. The texts are represented as a vector of integers (indexes). In order to make it easy for a practitioner to create their own applications, I will try to detail the necessary preprocessing. However, looking at the code, it becomes clear that data preprocessing part is skipped. I used the code as a guideline for the model. Hence, the task is similar to the Reuters news categorization task. So the task at hand is to use a lengthy description to interfere a (noisy) label. Explore it and a catalogue of free data sets across numerous topics below. The raw uncompressed data files contain approximately 6.2 million titles and approximately 9. The following COVID-19 data visualization is representative of the the types of visualizations that can be created using free public data sets. IMDb offers a great deal of useful structured information for research. I chose to randomly pick one genre in case of multiple assignments. tf.( path'imdb. With the information provided below, you can explore a number of free, accessible data sets and begin to create your own analyses. Most movies have multiple genres assigned (e.g. The dataset consists of movies released on or before July 2017. Publication manual of the American Psychological Association (7th ed). To see if that is possible I downloaded the raw data from an FU-Berlin ftp- server. Standard Format Adapted from American Psychological Association. While sentiment classification is an interesting topic, I wanted to see if it is possible to identify a movie’s genre from its description. Keras provides access to some part of the cleaned dataset (e.g. Java is a registered trademark of Oracle and/or its affiliates.The Internet Movie Database (Imdb) is a great source to get information about movies.

We provide a set of 25,000 highly polar movie reviews for training,Īnd 25,000 for testing. The available datasets are as follows: Content - Contains the following information for titles: titleId (string) - a tconst, an alphanumeric unique identifier of the title. ![]() See the README file contained in the release for more details.
