When hearing the term beacon, people might think of flares or a lighthouse at first. It can certainly be a guide in the ocean of different authority files on the web. In this post, I will take a closer look at BEACON files, their implementation and why...
In the first post of this series, I looked at how to achieve parallel execution in Python using multiprocessing and discussed how this is unsuitable with WSGI-based web frameworks because WSGI only allows the web server to create new processes, not the...

During development of the new African Studies Library online portal, I was faced with the task to implement an authority based search system. Without a more detailed specification, I first had to figure out, what that could be and how to implement it.

The BIOfid Semantic Search Within the BIOfid-project, we create a semantic search portal (hereafter “BIOfid portal”) to help our users to access legacy biodiversity literature more easily. Hence, since the BIOfid portal has a deeper “understanding” of both the texts and the included species, it allows the users to get more relevant documents. Moreover, the BIOfid portal interprets the user query and transform it ad hoc into a graph database query, to learn more about their intention.
Strolling through library shelves on graphs' edges During development of the new African Studies Library online portal, I was faced with the task to implement an authority based search system. Without a more detailed specification, I first had to figure out, what that could be and how to implement it.
The authority data to be used were datasets provided by the German “Gemeinsame Normdatei”, GND for short. That is all fine and well, but nobody would enter GND-Identifiers like https://d-nb.
Python, popular though it is, has a few well-known weaknesses. One of the most well known among serious users of the language is the lack of multicore support for in-process threads. This is because CPython, Python’s standard implementation has a global interpreter lock (often referred to as the GIL). The GIL locks each instance of the interpreter to a single core—a common approach to avoid race conditions in the implementation of language interpreters.
