prezo - Presentation Management
Experience a technical talk on this solution by attending DevNet Create 2021 Tech topic 2: Simplicity & Cloud-First, Do you have any slides …….?. The recording of the presentation is available for viewing on DevNet or by searching for the DevNet Youtube channel.
This project aims to enable sharing of PowerPoint presentations while using metadata to locate relevant content.
I began working on this solution to address my frustration with a lack of a suitable content management system enabling sharing presentations and their associated artifacts. vbrick enables a video content management system that includes storing the associated presentation files and tagging for internal versus external access and analytics.
For published webinars, this is an excellent solution; however, what I need is to share presentation material before and after the event.
Additional motivations include:
- developing a better understanding of object storage,
- understanding of the challenges of programatically extracting text from PowerPoint files,
- enable intelligent string matching to return relevant results.
What isn't addressed:
- advice or training on how to create and deliver compelling presentations,
- developing an enterprise-wide offering 2.
With this aside, let's look at the solution components.
I have worked for many years as a Technical Marketing Engineer at several technology companies and, more recently, as the organizer for a Meetup group focused on enabling programmability, automation, and Infrastructure as Code to develop NetDevOps skills.
These roles require technical knowledge of the solution components, marketing understanding, and communication skills.
Powerpoint is commonly used to foster communication in face-to-face customer meetings, webinars, and video conference meetings.
Presentations are strategic communications. 1 - Ontra, 2018, p. 24 Unfortunately, outside of a corporate overview deck, most are relegated to the hard drive of the author or scattered across collaboration app (MS Teams, Webex Teams, Slack) channels.
Object storage is popular for storing photos, audio files (MP3), and services like DropBox / Box, which are used to store massive amounts of unstructured data. Object storage associates the object with a globally unique ID and the inclusion of metadata and tags to enable searching for objects sharing similar characteristics.
Powerpoint files are primarily 3 - unstructured data. These files contain text and images and meta-data fields in the Summary / Properties. The meta-data files are typically ignored by most authors but can be used to document the Title, Subject, Author, Company, Category, and Keywords. Applying discipline to update the metadata is recommended.
In this project, we use the MinIO Python SDK to upload, search and retrieve objects stored in Amazon S3 (Amazon Simple Storage Service), the object storage service of AWS. This session demonstrates how the open-source Python library python-pptx and RAKE (Rapid Automatic Keyword Extraction) are used to extract and analyze keywords from PowerPoint files providing metadata to these objects stored in S3.
This solution includes the following tools.
Minio is an open-source object storage system that provides a consistent view of data regardless of where it resides in Google, Microsoft, or Amazon's cloud, in your private cloud, or in a co-location service. Data that resides in AWS today may be in a co-location tomorrow and in your private data center. The Minio Python SDK is used to upload PowerPoint presentations from a laptop to an Amazon S3 bucket
The Python library python-pptx extracts the text and tags from each PowerPoint presentation.
The Python library rake-nltk (Rapid Automatic Keyword Extraction algorithm) determines key phrases and loads them as metadata to the object. See 4 NLP keyword extraction tutorial with RAKE and Maui for a keyword extraction tutorial.
After the objects are loaded in their target bucket(s), we use the MinIO Python SDK to query the metadata of all the objects and use the FuzzyWuzzy Python library for string matching.
